Olanzapine And Fluoxetine Capsule
FDA Label NDC 42291-652

Suicidal Thoughts and Behaviors — Antidepressants increased the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term studies. These studies did not show an increase in the risk of suicidal thoughts and behavior with antidepressant use in patients over age 24; there was a reduction in risk with antidepressant use in patients aged 65 and older.

In patients of all ages who are started on antidepressant therapy, monitor closely for worsening and emergence of suicidal thoughts and behaviors. Advise families and caregivers of the need for close observation and communication with the prescriber. Olanzapine and fluoxetine capsules are not approved for use in children less than 10 years of age [see Warnings and Precautions (5.1), Use in Specific Populations (8.4), and Patient Counseling Information (17.2)].

Increased Mortality in Elderly Patients with Dementia-Related Psychosis — Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Olanzapine and fluoxetine capsules are not approved for the treatment of patients with dementia-related psychosis [see Warnings and Precautions (5.2)].

Olanzapine and fluoxetine capsules are indicated for the treatment of:

• Acute depressive episodes in Bipolar I Disorder [see Clinical Studies (14.1)].
• Treatment resistant depression (Major Depressive Disorder in patient who do not respond to 2 separate trials of different antidepressants of adequate dose and duration in the current episode) [see Clinical Studies (14.2)].

Adults – Administer olanzapine and fluoxetine capsules once daily in the evening, generally beginning with the 6 mg/25 mg (mg olanzapine/mg equivalent fluoxetine) capsule. While food has no appreciable effect on the absorption of olanzapine and fluoxetine given individually, the effect of food on the absorption of olanzapine and fluoxetine capsules has not been studied. Make dosage adjustments, if indicated, according to efficacy and tolerability. Antidepressant efficacy was demonstrated with olanzapine and fluoxetine capsules in a dose range of olanzapine 6 mg to 12 mg and fluoxetine 25 mg to 50 mg [see Clinical Studies (14.1)]. The safety of doses above 18 mg of olanzapine and 75 mg of fluoxetine has not been evaluated in adult clinical studies. Periodically reexamine the need for continued pharmacotherapy.

Children and Adolescents (10 to 17 years of age) — Administer olanzapine and fluoxetine capsules once daily in the evening, generally beginning with the 3 mg/25 mg capsule, without regard to meals, with a recommended target dose within the approved dosing range (6/25; 6/50; 12/25; 12/50 mg) [see Clinical Studies ( (14.1)]. The safety of doses above 12 mg of olanzapine and 50 mg of fluoxetine has not been evaluated in pediatric clinical studies. Periodically reexamine the need for continued pharmacotherapy.

Administer olanzapine and fluoxetine capsules once daily in the evening, generally beginning with the 6 mg/25 mg capsule. While food has no appreciable effect on the absorption of olanzapine and fluoxetine given individually, the effect of food on the absorption of olanzapine and fluoxetine capsules has not been studied. Adjust dosage, if indicated, according to efficacy and tolerability. Antidepressant efficacy was demonstrated with olanzapine and fluoxetine capsules in a dose range of olanzapine 6 mg to 18 mg and fluoxetine 25 mg to 50 mg [see Clinical Studies (14.2)]. The safety of doses above 18 mg/75 mg has not been evaluated in clinical studies. Periodically reexamine the need for continued pharmacotherapy.

Start olanzapine and fluoxetine capsules at 3 mg/25 mg or 6 mg/25 mg in patients with a predisposition to hypotensive reactions, patients with hepatic impairment, or patients who exhibit a combination of factors that may slow the metabolism of olanzapine and fluoxetine capsules (female gender, geriatric age, nonsmoking status) or those patients who may be pharmacodynamically sensitive to olanzapine. Titrate slowly and adjust dosage as needed in patients who exhibit a combination of factors that may slow metabolism. Olanzapine and fluoxetine capsules have not been systematically studied in patients >65 years of age or in patients <10 years of age [see Warnings and Precautions (5.21), Use in Specific Populations (8.5), and Clinical Pharmacology (12.3, 12.4)].

Treatment of Pregnant Women — When treating pregnant women with fluoxetine, a component of olanzapine and fluoxetine capsules, the physician should carefully consider the potential risks and potential benefits of treatment. Neonates exposed to SSRIs or SNRIs late in the third trimester have developed complications requiring prolonged hospitalizations, respiratory support, and tube feeding [see Use in Specific Populations (8.1)].

At least 14 days should elapse between discontinuation of an MAOI intended to treat psychiatric disorders and initiation of therapy with olanzapine and fluoxetine capsules. Conversely, at least 5 weeks should be allowed after stopping olanzapine and fluoxetine capsules before starting an MAOI intended to treat psychiatric disorders [see Contraindications (4.1)].

Do not start olanzapine and fluoxetine capsules in a patient who is being treated with linezolid or intravenous methylene blue because there is an increased risk of serotonin syndrome. In a patient who requires more urgent treatment of a psychiatric condition, other interventions, including hospitalization, should be considered [see Contraindications (4.1)].

In some cases, a patient already receiving olanzapine and fluoxetine capsule therapy may require urgent treatment with linezolid or intravenous methylene blue. If acceptable alternatives to linezolid or intravenous methylene blue treatment are not available and the potential benefits of linezolid or intravenous methylene blue are judged to outweigh the risks of serotonin syndrome in a particular patient, olanzapine and fluoxetine capsules should be stopped promptly, and linezolid or intravenous methylene blue can be administered. The patient should be monitored for symptoms of serotonin syndrome for five weeks or until 24 hours after the last dose of linezolid or intravenous methylene blue, whichever comes first. Therapy with olanzapine and fluoxetine capsules may be resumed 24 hours after the last dose of linezolid or intravenous methylene blue [see Warnings and Precautions (5.6)].

The risk of administering methylene blue by non-intravenous routes (such as oral tablets or by local injection) or in intravenous doses much lower than 1 mg/kg with olanzapine and fluoxetine capsules is unclear. The clinician should, nevertheless, be aware of the possibility of emergent symptoms of serotonin syndrome with such use [see Warnings and Precautions (5.6)].

Symptoms associated with discontinuation of fluoxetine, a component of olanzapine and fluoxetine capsules, SNRIs, and SSRIs, have been reported [see Warnings and Precautions (5.25)].

Capsules (mg olanzapine, USP/mg equivalent fluoxetine):

• 3 mg/25 mg
• 6 mg/25 mg
• 6 mg/50 mg
• 12 mg/25 mg
• 12 mg/50 mg

The use of MAOIs intended to treat psychiatric disorders with olanzapine and fluoxetine capsules or within 5 weeks of stopping treatment with olanzapine and fluoxetine capsules is contraindicated because of an increased risk of serotonin syndrome. The use of olanzapine and fluoxetine capsules within 14 days of stopping an MAOI intended to treat psychiatric disorders is also contraindicated [see Dosage and Administration (2.4) and Warnings and Precautions (5.6)].

Starting olanzapine and fluoxetine capsules in a patient who is being treated with MAOIs such as linezolid or intravenous methylene blue is also contraindicated because of an increased risk of serotonin syndrome [see Dosage and Administration (2.5)and Warnings and Precautions (5.6)].

• Pimozide [see Warnings and Precautions (5.20) and Drug Interactions (7.7, 7.8)]
• Thioridazine [see Warnings and Precautions (5.20) and Drug Interactions (7.7, 7.8)]

Pimozide and thioridazine prolong the QT interval. Olanzapine and fluoxetine capsules can increase the levels of pimozide and thioridazine through inhibition of CYP2D6. Olanzapine and fluoxetine capsules can also prolong the QT interval.

Patients with Major Depressive Disorder (MDD), both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications, and this risk may persist until significant remission occurs. Suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide. There has been a long-standing concern, however, that antidepressants may have a role in inducing worsening of depression and the emergence of suicidality in certain patients during the early phases of treatment. Pooled analyses of short-term placebo-controlled trials of antidepressant drugs (SSRIs and others) showed that these drugs increase the risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults (ages 18 to 24) with Major Depressive Disorder (MDD) and other psychiatric disorders. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction with antidepressants compared to placebo in adults aged 65 and older.

The pooled analyses of placebo-controlled trials in children and adolescents with MDD, Obsessive Compulsive Disorder (OCD), or other psychiatric disorders included a total of 24 short-term trials of 9 antidepressant drugs in over 4400 patients. The pooled analyses of placebo-controlled trials in adults with MDD or other psychiatric disorders included a total of 295 short-term trials (median duration of 2 months) of 11 antidepressant drugs in over 77,000 patients. There was considerable variation in risk of suicidality among drugs, but a tendency toward an increase in the younger patients for almost all drugs studied. There were differences in absolute risk of suicidality across the different indications, with the highest incidence in MDD. The risk differences (drug versus placebo), however, were relatively stable within age strata and across indications. These risk differences (drug-placebo difference in the number of cases of suicidality per 1000 patients treated) are provided in Table 1.

No suicides occurred in any of the pediatric trials. There were suicides in the adult trials, but the number was not sufficient to reach any conclusion about drug effect on suicide.

It is unknown whether the suicidality risk extends to longer-term use, i.e., beyond several months. However, there is substantial evidence from placebo-controlled maintenance trials in adults with depression that the use of antidepressants can delay the recurrence of depression.

All patients being treated with antidepressants for any indication should be monitored appropriately and observed closely for clinical worsening, suicidality, and unusual changes in behavior, especially during the initial few months of a course of drug therapy, or at times of dose changes, either increases or decreases.

The following symptoms, anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia (psychomotor restlessness), hypomania, and mania, have been reported in adult and pediatric patients being treated with antidepressants for Major Depressive Disorder as well as for other indications, both psychiatric and nonpsychiatric. Although a causal link between the emergence of such symptoms and either the worsening of depression and/or the emergence of suicidal impulses has not been established, there is concern that such symptoms may represent precursors to emerging suicidality.

Consideration should be given to changing the therapeutic regimen, including possibly discontinuing the medication, in patients whose depression is persistently worse, or who are experiencing emergent suicidality or symptoms that might be precursors to worsening depression or suicidality, especially if these symptoms are severe, abrupt in onset, or were not part of the patient’s presenting symptoms.

If the decision has been made to discontinue treatment, medication should be tapered, as rapidly as is feasible, but with recognition that abrupt discontinuation can be associated with certain symptoms [ see Warnings and Precautions (5.25)].

Families and caregivers of patients being treated with antidepressants for Major Depressive Disorder or other indications, both psychiatric and nonpsychiatric, should be alerted about the need to monitor patients for the emergence of agitation, irritability, unusual changes in behavior, and the other symptoms described above, as well as the emergence of suicidality, and to report such symptoms immediately to health care providers. Such monitoring should include daily observation by families and caregivers. Prescriptions for olanzapine and fluoxetine capsules should be written for the smallest quantity of capsules consistent with good patient management, in order to reduce the risk of overdose.

It should be noted that olanzapine and fluoxetine capsules are not approved for use in treating any indications in patients less than 10 years of age [ see Use in Specific Populations ( 8.4) ].

Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Olanzapine and fluoxetine capsules are not approved for the treatment of patients with dementia-related psychosis [ see Boxed Warning, Warnings and Precautions ( 5.21), and Patient Counseling Information ( 17.3) ].

In olanzapine placebo-controlled clinical trials of elderly patients with dementia-related psychosis, the incidence of death in olanzapine-treated patients was significantly greater than placebo-treated patients (3.5% vs 1.5%, respectively).

Meta-Analysis of Antipsychotic Use in Dementia-Related Psychosis – Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of seventeen placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10 week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group. Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality. The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear. Olanzapine and fluoxetine capsules are not approved for the treatment of patients with dementia-related psychosis [ see Warnings and Precautions ( 5.21) and Patient Counseling Information ( 17.3) ].

Cerebrovascular Adverse Events (CVAE), Including Stroke — Cerebrovascular adverse events (e.g., stroke, transient ischemic attack), including fatalities, were reported in patients in trials of olanzapine in elderly patients with dementia-related psychosis. In placebo-controlled trials, there was a significantly higher incidence of cerebrovascular adverse events in patients treated with olanzapine compared to patients treated with placebo. Olanzapine and olanzapine and fluoxetine capsules are not approved for the treatment of patients with dementia-related psychosis [ see Boxed Warning and Patient Counseling Information ( 17.3) ].

A potentially fatal symptom complex sometimes referred to as NMS has been reported in association with administration of antipsychotic drugs, including olanzapine. Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmia). Additional signs may include elevated creatinine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure.

The diagnostic evaluation of patients with this syndrome is complicated. In arriving at a diagnosis, it is important to exclude cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system pathology.

The management of NMS should include: 1) immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy, 2) intensive symptomatic treatment and medical monitoring, and 3) treatment of any concomitant serious medical problems for which specific treatments are available. There is no general agreement about specific pharmacological treatment regimens for NMS.

If after recovering from NMS, a patient requires treatment with an antipsychotic, the patient should be carefully monitored, since recurrences of NMS have been reported [ see Warnings and Precautions ( 5.5) and Patient Counseling Information ( 17.4, 17.9) ].

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) has been reported with olanzapine exposure. DRESS may present with a cutaneous reaction (such as rash or exfoliative dermatitis), eosinophilia, fever, and/or lymphadenopathy with systemic complications such as hepatitis, nephritis, pneumonitis, myocarditis, and/or pericarditis. DRESS is sometimes fatal. Discontinue olanzapine and fluoxetine capsules if DRESS is suspected [see Patient Counseling Information ( 17.5)].

Atypical antipsychotic drugs have been associated with metabolic changes including hyperglycemia, dyslipidemia, and weight gain. Metabolic changes may be associated with increased cardiovascular/cerebrovascular risk. Olanzapine’s specific metabolic profile is presented below.

Hyperglycemia and Diabetes Mellitus

Adults — Physicians should consider the risks and benefits when prescribing olanzapine and fluoxetine capsules to patients with an established diagnosis of diabetes mellitus, or having borderline increased blood glucose level (fasting 100 to 126 mg/dL, nonfasting 140 to 200 mg/dL). Patients taking olanzapine and fluoxetine capsules should be monitored regularly for worsening of glucose control. Patients starting treatment with olanzapine and fluoxetine capsules should undergo fasting blood glucose testing at the beginning of treatment and periodically during treatment. Any patient treated with atypical antipsychotics should be monitored for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness. Patients who develop symptoms of hyperglycemia during treatment with atypical antipsychotics should undergo fasting blood glucose testing. In some cases, hyperglycemia has resolved when the atypical antipsychotic was discontinued; however, some patients required continuation of anti-diabetic treatment despite discontinuation of the suspect drug [see Patient Counseling Information (17.6)].

Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported in patients treated with atypical antipsychotics, including olanzapine alone, as well as olanzapine taken concomitantly with fluoxetine. Assessment of the relationship between atypical antipsychotic use and glucose abnormalities is complicated by the possibility of an increased background risk of diabetes mellitus in patients with schizophrenia and the increasing incidence of diabetes mellitus in the general population. Epidemiological studies suggest an increased risk of treatment-emergent hyperglycemia-related adverse reactions in patients treated with the atypical antipsychotics. While relative risk estimates are inconsistent, the association between atypical antipsychotics and increases in glucose levels appears to fall on a continuum and olanzapine appears to have a greater association than some other atypical antipsychotics.

Mean increases in blood glucose have been observed in patients treated (median exposure of 9.2 months) with olanzapine in phase 1 of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE). The mean increase of serum glucose (fasting and nonfasting samples) from baseline to the average of the 2 highest serum concentrations was 15.0 mg/dL.

In a study of healthy volunteers, subjects who received olanzapine (N=22) for 3 weeks had a mean increase compared to baseline in fasting blood glucose of 2.3 mg/dL. Placebo-treated subjects (N=19) had a mean increase in fasting blood glucose compared to baseline of 0.34 mg/dL.

In an analysis of 7 controlled clinical studies, 2 of which were placebo-controlled, with treatment duration up to 12 weeks, olanzapine and fluoxetine capsules were associated with a greater mean change in random glucose compared to placebo (+8.65 mg/dL vs -3.86 mg/dL). The difference in mean changes between olanzapine and fluoxetine capsules and placebo was greater in patients with evidence of glucose dysregulation at baseline (including those patients diagnosed with diabetes mellitus or related adverse reactions, patients treated with anti-diabetic agents, patients with a baseline random glucose level ≥200 mg/dL, or a baseline fasting glucose level ≥126 mg/dL). Olanzapine and fluoxetine capsule-treated patients had a greater mean HbA _1c increase from baseline of 0.15% (median exposure 63 days), compared to a mean HbA _1c decrease of 0.04% in fluoxetine-treated subjects (median exposure 57 days) and a mean HbA _1c increase of 0.12% in olanzapine-treated patients (median exposure 56 days).

In an analysis of 6 controlled clinical studies, a larger proportion of olanzapine and fluoxetine capsule-treated subjects had glycosuria (4.4%) compared to placebo-treated subjects (1.4%).

The mean change in nonfasting glucose in patients exposed at least 48 weeks was +5.9 mg/dL (N=425).

Table 2 shows short-term and long-term changes in random glucose levels from adult olanzapine and fluoxetine capsule studies.

In a 47 week olanzapine and fluoxetine capsule study, the mean change from baseline to endpoint in fasting glucose was +4.81 mg/dL (n=130). Table 3 shows the categorical changes in fasting glucose [see Clinical Studies ( 14.2)].

^a Not Applicable ^.

Controlled fasting glucose data is limited for olanzapine and fluoxetine capsules; however, in an analysis of 5 placebo-controlled olanzapine monotherapy studies with treatment duration up to 12 weeks, olanzapine was associated with a greater mean change in fasting glucose levels compared to placebo (+2.76 mg/dL vs +0.17 mg/dL).

The mean change in fasting glucose for olanzapine-treated patients exposed at least 48 weeks was +4.2 mg/dL (N=487). In analyses of patients who completed 9 to 12 months of olanzapine therapy, mean change in fasting and nonfasting glucose levels continued to increase over time.

Children and Adolescents — In a single, 8 week, randomized, placebo-controlled clinical trial investigating olanzapine and fluoxetine capsules for treatment of bipolar I depression in patients 10 to 17 years of age, there were no clinically meaningful differences observed between olanzapine and fluoxetine capsules and placebo for mean change in fasting glucose levels. Table 4 shows categorical changes in fasting blood glucose from the pediatric olanzapine and fluoxetine capsules study.

Olanzapine Monotherapy in Adolescents — In an analysis of 3 placebo-controlled olanzapine monotherapy studies of adolescent patients, including those with Schizophrenia (6 weeks) or Bipolar I Disorder (manic or mixed episodes) (3 weeks), olanzapine was associated with a greater mean change from baseline in fasting glucose levels compared to placebo (+2.68 mg/dL vs -2.59 mg/dL). The mean change in fasting glucose for adolescents exposed at least 24 weeks was +3.1 mg/dL (N=121). Table 5 shows short-term and long-term changes in fasting blood glucose from adolescent olanzapine monotherapy studies.

Dyslipidemia

Undesirable alterations in lipids have been observed with olanzapine and fluoxetine capsule use. Clinical monitoring, including baseline and periodic follow-up lipid evaluations in patients using olanzapine and fluoxetine capsules, is recommended [see Patient Counseling Information ( 17.7)].

Adults — Clinically meaningful, and sometimes very high (>500 mg/dL), elevations in triglyceride levels have been observed with olanzapine and fluoxetine capsule use. Clinically meaningful increases in total cholesterol have also been seen with olanzapine and fluoxetine capsule use.

In an analysis of 7 controlled clinical studies, 2 of which were placebo-controlled, with treatment duration up to 12 weeks, olanzapine and fluoxetine capsule-treated patients had an increase from baseline in mean random total cholesterol of 12.1 mg/dL compared to an increase from baseline in mean random total cholesterol of 4.8 mg/dL for olanzapine-treated patients and a decrease in mean random total cholesterol of 5.5 mg/dL for placebo-treated patients. Table 6 shows categorical changes in nonfasting lipid values.

In long-term olanzapine and fluoxetine in combination studies (at least 48 weeks), changes (at least once) in nonfasting total cholesterol from normal at baseline to high occurred in 12% (N=150) and changes from borderline to high occurred in 56.6% (N=143) of patients. The mean change in nonfasting total cholesterol was 11.3 mg/dL (N=426).

A 47 week olanzapine and fluoxetine capsule study demonstrated mean changes from baseline to endpoint in fasting total cholesterol (+1.24 mg/dL), LDL cholesterol (+0.29 mg/dL), direct HDL cholesterol (-2.13 mg/dL), and triglycerides (+11.33 mg/dL). Table 7 shows the categorical changes in fasting lipids [see Clinical Studies ( 14.2)].

^a Not Applicable.

Fasting lipid data is limited for olanzapine and fluoxetine capsules; however, in an analysis of 5 placebo-controlled olanzapine monotherapy studies with treatment duration up to 12 weeks, olanzapine-treated patients had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 5.3 mg/dL, 3.0 mg/dL, and 20.8 mg/dL respectively compared to decreases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 6.1 mg/dL, 4.3 mg/dL, and 10.7 mg/dL for placebo-treated patients. For fasting HDL cholesterol, no clinically meaningful differences were observed between olanzapine-treated patients and placebo-treated patients. Mean increases in fasting lipid values (total cholesterol, LDL cholesterol, and triglycerides) were greater in patients without evidence of lipid dysregulation at baseline, where lipid dysregulation was defined as patients diagnosed with dyslipidemia or related adverse reactions, patients treated with lipid lowering agents, patients with high baseline lipid levels.

In long-term olanzapine studies (at least 48 weeks), patients had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 5.6 mg/dL, 2.5 mg/dL, and 18.7 mg/dL, respectively, and a mean decrease in fasting HDL cholesterol of 0.16 mg/dL. In an analysis of patients who completed 12 months of therapy, the mean nonfasting total cholesterol did not increase further after approximately 4 to 6 months.

The proportion of olanzapine-treated patients who had changes (at least once) in total cholesterol, LDL cholesterol or triglycerides from normal or borderline to high, or changes in HDL cholesterol from normal or borderline to low, was greater in long-term studies (at least 48 weeks) as compared with short-term studies. Table 8 shows categorical changes in fasting lipids values.

^a Not Applicable.

In phase 1 of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE), over a median exposure of 9.2 months, the mean increase in triglycerides in patients taking olanzapine was 40.5 mg/dL. In phase 1 of CATIE, the median increase in total cholesterol was 9.4 mg/dL.

Children and Adolescents — In a single, 8 week, randomized, placebo-controlled clinical trial investigating olanzapine and fluoxetine capsules for treatment of bipolar I depression in patients 10 to 17 years of age, there were clinically meaningful and statistically significant differences observed between olanzapine and fluoxetine capsules and placebo for mean change in fasting total cholesterol (+16.3 mg/dL vs. -4.3 mg/dL, respectively), LDL cholesterol (+9.7 mg/dL vs -3.5 mg/dL, respectively), and triglycerides (+35.4 mg/dL vs. -3.5 mg/dL, respectively).

The magnitude and frequency of changes in lipids were greater in children and adolescents than previously observed in adults. Table 9 shows categorical changes in fasting lipids values from the pediatric olanzapine and fluoxetine capsules study.

Olanzapine Monotherapy in Adolescents — In an analysis of 3 placebo-controlled olanzapine monotherapy studies of adolescents, including those with Schizophrenia (6 weeks) or Bipolar I Disorder (manic or mixed episodes) (3 weeks), olanzapine-treated adolescents had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 12.9 mg/dL, 6.5 mg/dL, and 28.4 mg/dL, respectively, compared to increases from baseline in mean fasting total cholesterol and LDL cholesterol of 1.3 mg/dL and 1.0 mg/dL, and a decrease in triglycerides of 1.1 mg/dL for placebo-treated adolescents. For fasting HDL cholesterol, no clinically meaningful differences were observed between olanzapine-treated adolescents and placebo-treated adolescents.

In long-term olanzapine studies (at least 24 weeks), adolescents had increases from baseline in mean fasting total cholesterol, LDL cholesterol, and triglycerides of 5.5 mg/dL, 5.4 mg/dL, and 20.5 mg/dL, respectively, and a mean decrease in fasting HDL cholesterol of 4.5 mg/dL. Table 10 shows categorical changes in fasting lipids values in adolescents.

Weight Gain

Potential consequences of weight gain should be considered prior to starting olanzapine and fluoxetine capsules. Patients receiving olanzapine and fluoxetine capsules should receive regular monitoring of weight [ see Patient Counseling Information (17.8)].

Adults — In an analysis of 7 controlled clinical studies, 2 of which were placebo-controlled, the mean weight increase for olanzapine and fluoxetine capsule-treated patients was greater than placebo-treated patients [4 kg (8.8 lb) vs -0.3 kg (-0.7 lb)]. Twenty-two percent of olanzapine and fluoxetine capsule-treated patients gained at least 7% of their baseline weight, with a median exposure to event of 6 weeks. This was greater than in placebo-treated patients (1.8%). Approximately 3% of olanzapine and fluoxetine capsule-treated patients gained at least 15% of their baseline weight, with a median exposure to event of 8 weeks. This was greater than in placebo-treated patients (0%). Clinically significant weight gain was observed across all baseline Body Mass Index (BMI) categories. Discontinuation due to weight gain occurred in 2.5% of olanzapine and fluoxetine capsule-treated patients and 0% of placebo-treated patients.

In long-term olanzapine and fluoxetine in combination studies (at least 48 weeks), the mean weight gain was 6.7 kg (14.7 lb) (median exposure of 448 days, N=431). The percentages of patients who gained at least 7%, 15% or 25% of their baseline body weight with long-term exposure were 66%, 33%, and 10%, respectively. Discontinuation due to weight gain occurred in 1.2% of patients treated with olanzapine and fluoxetine in combination following at least 48 weeks of exposure.

Table 11 presents the distribution of weight gain in a single long-term relapse prevention study of patients treated for up to 47 weeks with olanzapine and fluoxetine [see Clinical Studies (14.2)].

In long-term olanzapine studies (at least 48 weeks), the mean weight gain was 5.6 kg (12.3 lb) (median exposure of 573 days, N=2021). The percentages of patients who gained at least 7%, 15%, or 25% of their baseline body weight with long-term exposure were 64%, 32%, and 12%, respectively. Discontinuation due to weight gain occurred in 0.4% of olanzapine-treated patients following at least 48 weeks of exposure.

Table 12 includes data on adult weight gain with olanzapine pooled from 86 clinical trials. The data in each column represent data for those patients who completed treatment periods of the durations specified.

Dose group differences with respect to weight gain have been observed. In a single 8 week randomized, double-blind, fixed-dose study comparing 10 (N=199), 20 (N=200) and 40 (N=200) mg/day of oral olanzapine in adult patients with schizophrenia or schizoaffective disorder, mean baseline to endpoint increase in weight (10 mg/day: 1.9 kg; 20 mg/day: 2.3 kg; 40 mg/day: 3 kg) was observed with significant differences between 10 vs 40 mg/day.

Children and Adolescents — In a single, 8 week, randomized, placebo-controlled clinical trial investigating olanzapine and fluoxetine capsules for the treatment of bipolar I depression in patients 10 to 17 years of age, olanzapine and fluoxetine capsules were associated with greater mean change in weight compared to placebo (+4.4 kg vs +0.5 kg, respectively). The percentages of children and adolescents who gained at least 7%, 15%, or 25% of their baseline body weight with 8 week exposure were 52%, 14%, and 1%, respectively. The proportion of patients who had clinically significant weight gain was greater in children and adolescent patients compared to short-term data in adults. Discontinuation due to weight gain occurred in 2.9% of olanzapine and fluoxetine capsule-treated patients and 0% of placebo-treated patients. Table 13 depicts weight gain observed in the pediatric olanzapine and fluoxetine capsule study.

Olanzapine Monotherapy in Adolescents — Mean increase in weight in adolescents was greater than in adults. In 4 placebo-controlled trials, discontinuation due to weight gain occurred in 1% of olanzapine-treated patients, compared to 0% of placebo-treated patients.

In long-term olanzapine studies (at least 24 weeks), the mean weight gain was 11.2 kg (24.6 lb) (median exposure of 201 days, N=179). The percentages of adolescents who gained at least 7%, 15%, or 25% of their baseline body weight with long-term exposure were 89%, 55%, and 29%, respectively. Among adolescent patients, mean weight gain by baseline BMI category was 11.5 kg (25.3 lb), 12.1 kg (26.6 lb), and 12.7 kg (27.9 lb), respectively, for normal (N=106), overweight (N=26) and obese (N=17). Discontinuation due to weight gain occurred in 2.2% of olanzapine-treated patients following at least 24 weeks of exposure.

Table 15 shows data on adolescent weight gain with olanzapine pooled from 6 clinical trials. The data in each column represent data for those patients who completed treatment periods of the durations specified. Little clinical trial data is available on weight gain in adolescents with olanzapine beyond 6 months of treatment.

The development of a potentially life-threatening serotonin syndrome has been reported with SNRIs and SSRIs, including olanzapine and fluoxetine capsules, alone but particularly with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, and St. John's Wort) and with drugs that impair metabolism of serotonin (in particular, MAOIs, both those intended to treat psychiatric disorders and also others, such as linezolid and intravenous methylene blue).

Serotonin syndrome symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). Patients should be monitored for the emergence of serotonin syndrome. Serotonin syndrome symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). Patients should be monitored for the emergence of serotonin syndrome.

The concomitant use of olanzapine and fluoxetine capsules with MAOIs intended to treat psychiatric disorders is contraindicated. Olanzapine and fluoxetine capsules should also not be started in a patient who is being treated with MAOIs such as linezolid or intravenous methylene blue. All reports with methylene blue that provided information on the route of administration involved intravenous administration in the dose range of 1 mg/kg to 8 mg/kg. No reports involved the administration of methylene blue by other routes (such as oral tablets or local tissue injection) or at lower doses. There may be circumstances when it is necessary to initiate treatment with an MAOI such as linezolid or intravenous methylene blue in a patient taking olanzapine and fluoxetine capsules. Olanzapine and fluoxetine capsules should be discontinued before initiating treatment with the MAOI [ ]. The concomitant use of olanzapine and fluoxetine capsules with MAOIs intended to treat psychiatric disorders is contraindicated. Olanzapine and fluoxetine capsules should also not be started in a patient who is being treated with MAOIs such as linezolid or intravenous methylene blue. All reports with methylene blue that provided information on the route of administration involved intravenous administration in the dose range of 1 mg/kg to 8 mg/kg.

There may be circumstances when it is necessary to initiate treatment with an MAOI such as linezolid or intravenous methylene blue in a patient taking olanzapine and fluoxetine capsules. Olanzapine and fluoxetine capsules should be discontinued before initiating treatment with the MAOI [ see Dosage and Administration ( 2.4, 2.5) and Contraindications ( 4.1) ].

If concomitant use of olanzapine and fluoxetine capsules with other serotonergic drugs including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, buspirone, tryptophan, amphetamines, and St. John's Wort is clinically warranted, patients should be made aware of a potential increased risk for serotonin syndrome, particularly during treatment initiation and dose increases.

Treatment with olanzapine and fluoxetine capsules and any concomitant serotonergic agents should be discontinued immediately if the above events occur and supportive symptomatic treatment should be initiated.Treatment with olanzapine and fluoxetine capsules and any concomitant serotonergic agents should be discontinued immediately if the above events occur and supportive symptomatic treatment should be initiated.

Angle-Closure Glaucoma — The pupillary dilation that occurs following use of many antidepressant drugs including olanzapine and fluoxetine capsules may trigger an angle-closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy.

In olanzapine and fluoxetine capsule premarketing controlled clinical studies, the overall incidence of rash or allergic reactions in olanzapine and fluoxetine capsule-treated patients [4.6% (26/571)] was similar to that of placebo [5.2% (25/477)]. The majority of the cases of rash and/or urticaria were mild; however, 3 patients discontinued (1 due to rash, which was moderate in severity and 2 due to allergic reactions, 1 of which included face edema).

In fluoxetine U.S. clinical studies, 7% of 10,782 fluoxetine-treated patients developed various types of rashes and/or urticaria. Among the cases of rash and/or urticaria reported in premarketing clinical studies, almost a third were withdrawn from treatment because of the rash and/or systemic signs or symptoms associated with the rash. Clinical findings reported in association with rash include fever, leukocytosis, arthralgias, edema, carpal tunnel syndrome, respiratory distress, lymphadenopathy, proteinuria, and mild transaminase elevation. Most patients improved promptly with discontinuation of fluoxetine and/or adjunctive treatment with antihistamines or steroids, and all patients experiencing these reactions were reported to recover completely.

In fluoxetine premarketing clinical studies, 2 patients are known to have developed a serious cutaneous systemic illness. In neither patient was there an unequivocal diagnosis, but 1 was considered to have a leukocytoclastic vasculitis, and the other, a severe desquamating syndrome that was considered variously to be a vasculitis or erythema multiforme. Other patients have had systemic syndromes suggestive of serum sickness.

Since the introduction of fluoxetine, systemic reactions, possibly related to vasculitis, have developed in patients with rash. Although these reactions are rare, they may be serious, involving the lung, kidney, or liver. Death has been reported to occur in association with these systemic reactions.

Anaphylactoid reactions, including bronchospasm, angioedema, and urticaria alone and in combination, have been reported.

Pulmonary reactions, including inflammatory processes of varying histopathology and/or fibrosis, have been reported rarely. These reactions have occurred with dyspnea as the only preceding symptom.

Whether these systemic reactions and rash have a common underlying cause or are due to different etiologies or pathogenic processes is not known. Furthermore, a specific underlying immunologic basis for these reactions has not been identified. Upon the appearance of rash or of other possible allergic phenomena for which an alternative etiology cannot be identified, olanzapine and fluoxetine capsules should be discontinued.

A major depressive episode may be the initial presentation of Bipolar Disorder. It is generally believed (though not established in controlled trials) that treating such an episode with an antidepressant alone may increase the likelihood of precipitation of a manic episode in patients at risk for Bipolar Disorder. Whether any of the symptoms described for clinical worsening and suicide risk represent such a conversion is unknown . However, prior to initiating treatment with an antidepressant, patients with depressive symptoms should be adequately screened to determine if they are at risk for Bipolar Disorder; such screening should include a detailed psychiatric history, including a family history of suicide, Bipolar Disorder, and depression. It should be noted that olanzapine and fluoxetine capsules are approved for the acute treatment of depressive episodes associated with Bipolar I Disorder.

In the 3 controlled bipolar depression studies (2 in adults and 1 in children and adolescents [10 to 17 years of age]) there was no statistically significant difference in the incidence of manic reactions (manic reaction or manic depressive reaction) between olanzapine and fluoxetine capsule- and placebo-treated patients. In 1 adult study, the incidence of manic reactions was (7% [3/43]) in olanzapine and fluoxetine capsule-treated patients compared to (3% [5/184]) in placebo-treated patients. In the other adult study, the incidence of manic reactions was (2% [1/43]) in olanzapine and fluoxetine capsule-treated patients compared to (8% [15/193]) in placebo-treated patients. In a single, 8 week, randomized, placebo-controlled clinical trial investigating olanzapine and fluoxetine capsules for the treatment of bipolar I depression in patients 10 to 17 years of age, the incidence of manic reactions was (1% [2/170]) in olanzapine and fluoxetine capsule-treated patients compared to (0% [0/84]) in placebo-treated patients. Because of the cyclical nature of Bipolar I Disorder, patients should be monitored closely for the development of symptoms of mania/hypomania during treatment with olanzapine and fluoxetine capsules.

A syndrome of potentially irreversible, involuntary, dyskinetic movements may develop in patients treated with antipsychotic drugs. Although the prevalence of the syndrome appears to be highest among the elderly, especially elderly women, it is impossible to rely upon prevalence estimates to predict, at the inception of antipsychotic treatment, which patients are likely to develop the syndrome. Whether antipsychotic drug products differ in their potential to cause tardive dyskinesia is unknown.

The risk of developing tardive dyskinesia and the likelihood that it will become irreversible are believed to increase as the duration of treatment and the total cumulative dose of antipsychotic drugs administered to the patient increase. However, the syndrome can develop, although much less commonly, after relatively brief treatment periods at low doses or may even arise after discontinuation of treatment.

There is no known treatment for established cases of tardive dyskinesia, although the syndrome may remit, partially or completely, if antipsychotic treatment is withdrawn. Antipsychotic treatment itself, however, may suppress (or partially suppress) the signs and symptoms of the syndrome and thereby may possibly mask the underlying process. The effect that symptomatic suppression has upon the long-term course of the syndrome is unknown.

The incidence of dyskinetic movement in olanzapine and fluoxetine capsule-treated patients was infrequent. The mean score on the Abnormal Involuntary Movement Scale (AIMS) in the olanzapine and fluoxetine capsule-controlled database across clinical studies involving olanzapine and fluoxetine capsule-treated patients decreased from baseline. Nonetheless, olanzapine and fluoxetine capsules should be prescribed in a manner that is most likely to minimize the risk of tardive dyskinesia. If signs and symptoms of tardive dyskinesia appear in a patient on olanzapine and fluoxetine capsules, drug discontinuation should be considered. However, some patients may require treatment with olanzapine and fluoxetine capsules despite the presence of the syndrome. The need for continued treatment should be reassessed periodically.

Olanzapine and fluoxetine capsules may induce orthostatic hypotension associated with dizziness, tachycardia, bradycardia and, in some patients, syncope, especially during the initial dose-titration period [ see Patient Counseling Information (17.12)].

In the olanzapine and fluoxetine capsule-controlled clinical trials across all indications, there were no significant differences between olanzapine and fluoxetine capsule-treated patients and olanzapine, fluoxetine- or placebo-treated patients in exposure-adjusted rates of orthostatic systolic blood pressure decreases of at least 30 mm Hg. Orthostatic systolic blood pressure decreases of at least 30 mm Hg occurred in 4.0% (28/705), 2.3% (19/831), 4.5% (18/399), and 1.8% (8/442) of the olanzapine and fluoxetine capsules, olanzapine, fluoxetine, and placebo groups, respectively. In this group of studies, the incidence of syncope-related adverse reactions (i.e., syncope and/or loss of consciousness) in olanzapine and fluoxetine capsule-treated patients was 0.4% (3/771) compared to placebo 0.2% (1/477).

In a clinical pharmacology study of olanzapine and fluoxetine capsules, 3 healthy subjects were discontinued from the trial after experiencing severe, but self-limited, hypotension and bradycardia that occurred 2 to 9 hours following a single 12 mg/50 mg dose of olanzapine and fluoxetine capsules. Reactions consisting of this combination of hypotension and bradycardia (and also accompanied by sinus pause) have been observed in at least 3 other healthy subjects treated with various formulations of olanzapine (1 oral, 2 intramuscular). In controlled clinical studies, the incidence of patients with a ≥20 bpm decrease in orthostatic pulse concomitantly with a ≥20 mm Hg decrease in orthostatic systolic blood pressure was 0.3% (2/706) in the olanzapine and fluoxetine capsule group, 0.2% (1/445) in the placebo group, 0.7% (6/837) in the olanzapine group, and 0% (0/404) in the fluoxetine group.

Olanzapine and fluoxetine capsules should be used with particular caution in patients with known cardiovascular disease (history of myocardial infarction or ischemia, heart failure, or conduction abnormalities), cerebrovascular disease, or conditions that would predispose patients to hypotension (dehydration, hypovolemia, and treatment with antihypertensive medications).

Olanzapine and fluoxetine capsules may cause somnolence, postural hypotension, motor and sensory instability, which may lead to falls and, consequently, fractures or other injuries. For patients with diseases, conditions, or medications that could exacerbate these effects, complete fall risk assessments when initiating antipsychotic treatment and recurrently for patients on long-term antipsychotic therapy.

Class Effect — In clinical trial and/or postmarketing experience, events of leukopenia/neutropenia have been reported temporally related to antipsychotic agents, including olanzapine and fluoxetine capsules. Agranulocytosis has also been reported.

Possible risk factors for leukopenia/neutropenia include preexisting low white blood cell count (WBC) and history of drug induced leukopenia/neutropenia. Patients with a history of a clinically significant low WBC or drug induced leukopenia/neutropenia should have their complete blood count (CBC) monitored frequently during the first few months of therapy and discontinuation of olanzapine and fluoxetine capsules should be considered at the first sign of a clinically significant decline in WBC in the absence of other causative factors.

Patients with clinically significant neutropenia should be carefully monitored for fever or other symptoms or signs of infection and treated promptly if such symptoms or signs occur. Patients with severe neutropenia (absolute neutrophil count <1000/mm ³) should discontinue olanzapine and fluoxetine capsules and have their WBC followed until recovery.

Esophageal dysmotility and aspiration have been associated with antipsychotic drug use. Aspiration pneumonia is a common cause of morbidity and mortality in patients with advanced Alzheimer’s disease. Olanzapine and fluoxetine capsules are not approved for the treatment of patients with Alzheimer’s disease.

Seizures occurred in 0.2% (4/2547) of olanzapine and fluoxetine capsule-treated patients during open-label clinical studies. No seizures occurred in the controlled olanzapine and fluoxetine capsule studies. Seizures have also been reported with both olanzapine and fluoxetine monotherapy. Olanzapine and fluoxetine capsules should be used cautiously in patients with a history of seizures or with conditions that potentially lower the seizure threshold, e.g., Alzheimer’s dementia. Olanzapine and fluoxetine capsules are not approved for the treatment of patients with Alzheimer’s disease. Conditions that lower the seizure threshold may be more prevalent in a population of ≥65 years of age.

SNRIs and SSRIs, including fluoxetine, may increase the risk of bleeding reactions. Concomitant use of aspirin, non-steroidal anti-inflammatory drugs, warfarin, and other anti-coagulants may add to this risk. Case reports and epidemiological studies (case-control and cohort design) have demonstrated an association between use of drugs that interfere with serotonin reuptake and the occurrence of gastrointestinal bleeding. Bleeding reactions related to SNRIs and SSRIs use have ranged from ecchymoses, hematomas, epistaxis, and petechiae to life-threatening hemorrhages.

Patients should be cautioned about the risk of bleeding associated with the concomitant use of olanzapine and fluoxetine capsules and NSAIDs, aspirin, or other drugs that affect coagulation [ see Drug Interactions ( 7.4) and Patient Counseling Information ( 17.13)].

Hyponatremia has been reported during treatment with SNRIs and SSRIs, including fluoxetine and olanzapine and fluoxetine capsules. In many cases, this hyponatremia appears to be the result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH). Cases with serum sodium lower than 110 mmol/L have been reported and appeared to be reversible when [ see Use in Specific Populations ( 8.5) ] olanzapine and fluoxetine capsules were discontinued. Elderly patients may be at greater risk of developing hyponatremia with SNRIs and SSRIs. Also, patients taking diuretics or who are otherwise volume depleted may be at greater risk. Discontinuation of olanzapine and fluoxetine capsules should be considered in patients with symptomatic hyponatremia and appropriate medical intervention should be instituted.

Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which may lead to falls. More severe and/or acute cases have been associated with hallucination, syncope, seizure, coma, respiratory arrest, and death [ see Patient Counseling Information (17.14)].

Olanzapine and fluoxetine capsules have the potential to impair judgment, thinking, or motor skills. Patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that olanzapine and fluoxetine capsule therapy does not affect them adversely [ see Patient Counseling Information (17.15)].

Adults — Sedation-related adverse reactions were commonly reported with olanzapine and fluoxetine capsule treatment occurring at an incidence of 26.6% in olanzapine and fluoxetine capsule-treated patients compared with 10.9% in placebo-treated patients. Sedation-related adverse reactions (sedation, somnolence, hypersomnia, and lethargy) led to discontinuation in 2% (15/771) of patients in the controlled clinical studies.

Children and Adolescents — In a single, 8 week, randomized, placebo-controlled clinical trial investigating olanzapine and fluoxetine capsules for the treatment of bipolar I depression in patients 10 to 17 years of age, somnolence-related adverse events were commonly reported with olanzapine and fluoxetine capsule treatment occurring at an incidence of 23.5% in olanzapine and fluoxetine capsule-treated patients compared with 2.4% in placebo-treated patients. Somnolence-related adverse events led to discontinuation in 1.2% (2/170) of patients.

Disruption of the body’s ability to reduce core body temperature has been attributed to antipsychotic drugs. Appropriate care is advised when prescribing olanzapine and fluoxetine capsules for patients who will be experiencing conditions which may contribute to an elevation in core body temperature (e.g., exercising strenuously, exposure to extreme heat, receiving concomitant medication with anticholinergic activity, or being subject to dehydration) [ see Patient Counseling Information (17.16)].

Post-marketing cases of QT interval prolongation and ventricular arrhythmia including Torsade de Pointes have been reported in patients treated with fluoxetine. Olanzapine and fluoxetine capsules should be used with caution in patients with congenital long QT syndrome; a previous history of QT prolongation; a family history of long QT syndrome or sudden cardiac death; and other conditions that predispose to QT prolongation and ventricular arrhythmia. Such conditions include concomitant use of drugs that prolong the QT interval; hypokalemia or hypomagnesemia; recent myocardial infarction, uncompensated heart failure, bradyarrhythmias, and other significant arrhythmias; and conditions that predispose to increased fluoxetine exposure (overdose, hepatic impairment, use of CYP2D6 inhibitors, CYP2D6 poor metabolizer status, or use of other highly protein-bound drugs). Fluoxetine is primarily metabolized by CYP2D6 [ see Contraindications ( 4.2), Adverse Reactions ( 6), Drug Interactions ( 7.7, 7.8), Overdose ( 10.1), and Clinical Pharmacology ( 12.3) ].

Pimozide and thioridazine are contraindicated for use with olanzapine and fluoxetine capsules. Avoid the concomitant use of drugs known to prolong the QT interval. These include specific antipsychotics (e.g., ziprasidone, iloperidone, chlorpromazine, mesoridazine, droperidol); specific antibiotics (e.g., erythromycin, gatifloxacin, moxifloxacin, sparfloxacin); Class 1A antiarrhythmic medications (e.g., quinidine, procainamide); Class III antiarrhythmics (e.g., amiodarone, sotalol); and others (e.g., pentamidine, levomethadyl acetate, methadone, halofantrine, mefloquine, dolasetron mesylate, probucol or tacrolimus) [ see Drug Interactions ( 7.7, 7.8) and Clinical Pharmacology ( 12.3) ].

Consider ECG assessment and periodic ECG monitoring if initiating treatment with olanzapine and fluoxetine capsules in patients with risk factors for QT prolongation and ventricular arrhythmia. Consider discontinuing olanzapine and fluoxetine capsules and obtaining a cardiac evaluation if patients develop signs or symptoms consistent with ventricular arrhythmia.

In a single, 8 week, randomized, placebo-controlled clinical trial investigating olanzapine and fluoxetine capsules for the treatment of bipolar I depression in patients 10 to 17 years of age, there was a statistically significant difference in QT _c interval for patients treated with olanzapine and fluoxetine capsules compared with patients on placebo: mean change in QT _cF (Fridericia correction factor) from baseline to endpoint in patients treated with olanzapine and fluoxetine capsules was 8.2 msec (95% CI 6.2, 10.2). No patient developed QT _c increases ≥60 msec or QT _c ≥480 msec. Clinicians should use olanzapine and fluoxetine capsules with caution in those children or adolescents who are known to be particularly at risk for QT prolongation [ see Adverse Reactions ( 6.2) ].

The following precautions for the individual components may be applicable to olanzapine and fluoxetine capsules.
Olanzapine exhibits in vitro muscarinic receptor affinity. In premarketing clinical studies, olanzapine and fluoxetine capsules were associated with constipation, dry mouth, and tachycardia, all adverse reactions possibly related to cholinergic antagonism. Such adverse reactions were not often the basis for study discontinuations; olanzapine and fluoxetine capsules should be used with caution
in patients with a current diagnosis or prior history of urinary retention, clinically significant

As with other drugs that antagonize dopamine D receptors, olanzapine and fluoxetine capsules elevate prolactin levels, and the elevation persists during administration. Hyperprolactinemia may suppress hypothalamic GnRH, resulting in reduced pituitary gonadotropin secretion. This, in turn, may inhibit reproductive function by impairing gonadal steroidogenesis in both female and male patients. Galactorrhea, amenorrhea, gynecomastia, and erectile dysfunction have been reported in patients receiving prolactin-elevating compounds. Long-standing hyperprolactinemia when associated with hypogonadism may lead to decreased bone density in both female and male subjects.

Tissue culture experiments indicate that approximately one-third of human breast cancers are prolactin dependent , a factor of potential importance if the prescription of these drugs is contemplated in a patient with previously detected breast cancer. As is common with compounds that increase prolactin release, an increase in mammary gland neoplasia was observed in the olanzapine carcinogenicity studies conducted in mice and rats [ ]. Neither clinical studies nor epidemiologic studies conducted to date have shown an association between chronic administration of this class of drugs and tumorigenesis in humans; the available evidence is considered too limited to be conclusive at this time.

— In controlled clinical studies of olanzapine and fluoxetine capsules (up to 12 weeks), changes from normal to high in prolactin concentrations were observed in 28% of adults treated with olanzapine and fluoxetine capsules as compared to 5% of placebo-treated patients. The elevations persisted throughout administration of olanzapine and fluoxetine capsules. In a pooled analysis from clinical studies including 2929 adults treated with olanzapine and fluoxetine capsules, potentially associated clinical manifestations included menstrual-related events (1% [20/1946] of females), sexual function-related events (7% [192/2929] of females and males), and breast-related events (0.8% [16/1946] of females, 0.2% [2/983] of males).

In a pooled analysis from clinical studies including 2929 adults treated with olanzapine and fluoxetine capsules, potentially associated clinical manifestations included menstrual-related events ¹ (1% [20/1946] of females), sexual function-related events ² (7% [192/2929] of females and males), and breast-related events ³ (0.8% [16/1946] of females, 0.2% [2/983] of males).

— In a single, 8 week, randomized, placebo-controlled clinical trial investigating olanzapine and fluoxetine capsules for the treatment of bipolar I depression in patients 10 to 17 years of age, olanzapine and fluoxetine capsules were associated with a statistically significant greater mean change from baseline in prolactin levels compared to placebo (8.7 mcg/L vs 0.7 mcg/L, respectively). Although prolactin concentrations were very commonly (>10%) elevated above normal in both the olanzapine and fluoxetine capsules and placebo groups, more than twice as many olanzapine and fluoxetine capsule-treated patients were seen with these elevations compared to placebo-treated patients. Five patients experienced an adverse event potentially associated with elevated prolactin; these events included dysmenorrhoea, galactorrhoea, and ovulation disorder. Children and Adolescents — In a single, 8 week, randomized, placebo-controlled clinical trial investigating olanzapine and fluoxetine capsules for the treatment of bipolar I depression in patients 10 to 17 years of age, olanzapine and fluoxetine capsules were associated with a statistically significant greater mean change from baseline in prolactin levels compared to placebo (8.7 mcg/L vs 0.7 mcg/L, respectively).

The magnitude and frequency of change in prolactin in children and adolescents was larger than observed in adult patients treated with olanzapine and fluoxetine capsules, but was similar to that observed in adolescents treated with olanzapine monotherapy.The magnitude and frequency of change in prolactin in children and adolescents was larger than observed in adult patients treated with olanzapine and fluoxetine capsules, but was similar to that observed in adolescents treated with olanzapine monotherapy.

Olanzapine Monotherapy

In placebo-controlled olanzapine clinical studies (up to 12 weeks), changes from normal to high in prolactin concentrations were observed in 30% of adults treated with olanzapine as compared to 10.5% of adults treated with placebo. In a pooled analysis from clinical studies including 8136 adults treated with olanzapine, potentially associated clinical manifestations included menstrual-related events (2% [49/3240] of females), sexual function-related events (2% [150/8136] of females and males), and breast-related events (0.7% [23/3240] of females, 0.2% [9/4896] of males).

In placebo-controlled olanzapine monotherapy studies in adolescent patients (up to 6 weeks) with schizophrenia or bipolar I disorder (manic or mixed episodes), changes from normal to high in prolactin concentrations were observed in 47% of olanzapine-treated patients compared to 7% of placebo-treated patients. In a pooled analysis from clinical trials including 454 adolescents treated with olanzapine, potentially associated clinical manifestations included menstrual-related events (1% [2/168] of females), sexual function-related events (0.7% [3/454] of females and males), and breast-related events (2% [3/168] of females, 2% [7/286] of males) [ ].

Dose group differences with respect to prolactin elevation have been observed. In a single 8 week randomized, double-blind, fixed-dose study comparing 10 (n=199), 20 (n=200) and 40 (n=200) mg/day of oral olanzapine in adult patients with schizophrenia or schizoaffective disorder, incidence of prolactin elevation >24.2 ng/mL (female) or >18.77 ng/mL (male) at any time during the trial (10 mg/day: 31.2%; 20 mg/day: 42.7%; 40 mg/day: 61.1%) indicated significant differences between 10 vs 40 mg/day and 20 vs 40 mg/day Dose group differences with respect to prolactin elevation have been observed.

Olanzapine and fluoxetine capsules contain the same active ingredients that are in Zyprexa ^®, Zyprexa ^® Zydis ^®, Zyprexa ^® Relprevv ^TM (olanzapine), and in Prozac ^®, Prozac ^® Weekly ^™, and Sarafem ^® (fluoxetine HCl). Caution should be exercised when prescribing these medications concomitantly with olanzapine and fluoxetine capsules [ see Overdosage ( 10) ].

Because of the long elimination half-lives of fluoxetine and its major active metabolite, changes in dose will not be fully reflected in plasma for several weeks, affecting both strategies for titration to final dose and withdrawal from treatment. This is of potential consequence when drug discontinuation is required or when drugs are prescribed that might interact with fluoxetine and norfluoxetine following the discontinuation of fluoxetine [ see Clinical Pharmacology ( 12.3) ].

During marketing of fluoxetine, a component of olanzapine and fluoxetine capsules, SNRIs, and SSRIs, there have been spontaneous reports of adverse reactions occurring upon discontinuation of these drugs, particularly when abrupt, including the following: dysphoric mood, irritability, agitation, dizziness, sensory disturbances (e.g., paresthesias such as electric shock sensations), anxiety, confusion, headache, lethargy, emotional lability, insomnia, and hypomania. While these reactions are generally self-limiting, there have been reports of serious discontinuation symptoms. Patients should be monitored for these symptoms when discontinuing treatment with fluoxetine. A gradual reduction in the dose rather than abrupt cessation is recommended whenever possible. If intolerable symptoms occur following a decrease in the dose or upon discontinuation of treatment, then resuming the previously prescribed dose may be considered. Subsequently, the physician may continue decreasing the dose but at a more gradual rate. Plasma fluoxetine and norfluoxetine concentration decrease gradually at the conclusion of therapy, which may minimize the risk of discontinuation symptoms with this drug [ see Dosage and Administration ( 2.4) and Patient Counseling Information ( 17.18)].

Use of SSRIs, including fluoxetine a component of olanzapine and fluoxetine capsules, may cause symptoms of sexual dysfunction [see Adverse Reactions (6.1)]. In male patients, olanzapine and fluoxetine capsules use may result in ejaculatory delay or
failure, decreased libido, and erectile dysfunction. In female patients, olanzapine and fluoxetine capsules use may result in decreased libido and delayed or absent orgasm. It is important for prescribers to inquire about sexual function prior to initiation of
olanzapine and fluoxetine capsules and to inquire specifically about changes in sexual function during treatment, because sexual function may not be spontaneously reported. When evaluating changes in sexual function, obtaining a detailed history (including timing of symptom onset) is important because sexual symptoms may have other causes, including the underlying psychiatric disorder. Discuss potential management strategies to support patients in making informed decisions about treatment.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect or predict the rates observed in practice.

The data in the tables represent the proportion of individuals who experienced, at least once, a treatment-emergent adverse reaction of the type listed. A reaction was considered treatment-emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation.

Adults — The information below is derived from a clinical study database for olanzapine and fluoxetine capsules consisting of 2547 patients with treatment resistant depression, depressive episodes associated with Bipolar I Disorder, Major Depressive Disorder with psychosis, or sexual dysfunction with approximately 1085 patient-years of exposure. The conditions and duration of treatment with olanzapine and fluoxetine capsules varied greatly and included (in overlapping categories) open-label and double-blind phases of studies, inpatients and outpatients, fixed-dose and dose-titration studies, and short-term or long-term exposure.

Adverse Reactions Associated with Discontinuation of Treatment in Short-Term, Controlled Studies Including Depressive Episodes Associated with Bipolar I Disorder and Treatment Resistant Depression — Overall, 11.3% of the 771 patients in the olanzapine and fluoxetine capsule group discontinued due to adverse reactions compared with 4.4% of the 477 patients for placebo. Adverse reactions leading to discontinuation associated with the use of olanzapine and fluoxetine capsules (incidence of at least 1% for olanzapine and fluoxetine capsules and greater than that for placebo) using MedDRA Dictionary coding were weight increased (2%) and sedation (1%) versus placebo patients which had 0% incidence of weight increased and sedation.

Commonly Observed Adverse Reactions in Controlled Studies Including Depressive Episodes Associated with Bipolar I Disorder and Treatment Resistant Depression — In short-term studies, the most commonly observed adverse reactions associated with the use of olanzapine and fluoxetine capsules (incidence ≥5% and at least twice that for placebo in the olanzapine and fluoxetine capsule-controlled database) using MedDRA Dictionary coding were: disturbance in attention, dry mouth, fatigue, hypersomnia, increased appetite, peripheral edema, sedation, somnolence, tremor, vision blurred, and weight increased. Adverse reactions reported in clinical trials of olanzapine and fluoxetine in combination are generally consistent with treatment-emergent adverse reactions during olanzapine or fluoxetine monotherapy.

In a 47 week maintenance study in adults with treatment resistant depression, adverse reactions associated with olanzapine and fluoxetine capsule use were generally similar to those seen in short-term studies. Weight gain, hyperlipidemia, and hyperglycemia were observed in olanzapine and fluoxetine capsule -treated patients throughout the study.

Adverse Reactions Occurring at an Incidence of 2% or More in Short-Term Controlled Studies Including Depressive Episodes Associated with Bipolar I Disorder and Treatment Resistant Depression — Table 16 enumerates the treatment-emergent adverse reactions associated with the use of olanzapine and fluoxetine capsules (incidence of at least 2% for olanzapine and fluoxetine capsules and twice or more than for placebo). The olanzapine and fluoxetine capsule-controlled column includes patients with various diagnoses while the placebo column includes only patients with bipolar depression and major depression with psychotic features.

^a  Includes edema, edema peripheral, pitting edema, generalized edema, eyelid edema, face edema, gravitational edema,
   localized edema, periorbital edema, swelling,  joint swelling, swelling face, and eye swelling.

^b Includes somnolence, sedation, hypersomnia, and lethargy.

Extrapyramidal Symptoms

Dystonia, Class Effect for Antipsychotics — Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. Dystonic symptoms include: spasm of the neck muscles, sometimes progressing to tightness of the throat, swallowing difficulty, difficulty breathing, and/or protrusion of the tongue. While these symptoms can occur at low doses, the frequency and severity are greater with high potency and at higher doses of first generation antipsychotic drugs. In general, an elevated risk of acute dystonia may be observed in males and younger age groups receiving antipsychotics; however, events of dystonia have been reported infrequently (<1%) with the olanzapine and fluoxetine combination.

Additional Findings Observed in Clinical Studies

Sexual Dysfunction — In the pool of controlled olanzapine and fluoxetine capsule studies in patients with bipolar depression, there were higher rates of the treatment-emergent adverse reactions decreased libido, anorgasmia, erectile dysfunction and abnormal ejaculation in the olanzapine and fluoxetine capsule group than in the placebo group. One case of decreased libido led to discontinuation in the olanzapine and fluoxetine capsule group. In the controlled studies that contained a fluoxetine arm, the rates of decreased libido and abnormal ejaculation in the olanzapine and fluoxetine capsule group were less than the rates in the fluoxetine group. None of the differences were statistically significant.

Sexual dysfunction, including priapism, has been reported with all SSRIs. While it is difficult to know the precise risk of sexual dysfunction associated with the use of SSRIs, physicians should routinely inquire about such possible side effects.

There are no adequate and well-controlled studies examining sexual dysfunction with olanzapine and fluoxetine capsule or fluoxetine treatment. Symptoms of sexual dysfunction occasionally persist after discontinuation of fluoxetine treatment.

Difference Among Dose Levels Observed in Other Olanzapine Clinical Trials

In a single 8 week randomized, double-blind, fixed-dose study comparing 10 (N=199), 20 (N=200), and 40 (N=200) mg/day of olanzapine in patients with Schizophrenia or Schizoaffective Disorder, statistically significant differences among 3 dose groups were observed for the following safety outcomes: weight gain, prolactin elevation, fatigue, and dizziness. Mean baseline to endpoint increase in weight (10 mg/day: 1.9 kg; 20 mg/day: 2.3 kg; 40 mg/day: 3 kg) was observed with significant differences between 10 vs 40 mg/day. Incidence of treatment-emergent prolactin elevation >24.2 ng/mL (female) or >18.77 ng/mL (male) at any time during the trial (10 mg/day: 31.2%; 20 mg/day: 42.7%; 40 mg/day: 61.1%) with significant differences between 10 vs 40 mg/day and 20 vs 40 mg/day; fatigue (10 mg/day: 1.5%; 20 mg/day: 2.1%; 40 mg/day: 6.6%) with significant differences between 10 vs 40 and 20 vs 40 mg/day; and dizziness (10 mg/day: 2.6%; 20 mg/day: 1.6%; 40 mg/day: 6.6%) with significant differences between 20 vs 40 mg, was observed.

Other Adverse Reactions Observed in Clinical Studies

Following is a list of treatment-emergent adverse reactions reported by patients treated with olanzapine and fluoxetine capsules in clinical trials. This listing is not intended to include reactions (1) already listed in previous tables or elsewhere in labeling, (2) for which a drug cause was remote, (3) which were so general as to be uninformative, (4) which were not considered to have significant clinical implications, or (5) which occurred at a rate equal to or less than placebo.

² Adjusted for gender.

Other Adverse Reactions Observed with Olanzapine or Fluoxetine Monotherapy

The following adverse reactions were not observed in olanzapine and fluoxetine capsule-treated patients during premarketing clinical studies but have been reported with olanzapine or fluoxetine monotherapy: aplastic anemia, bruxism, cholestatic jaundice, diabetic coma, dysuria, eosinophilic pneumonia ³, erythema multiforme, esophageal ulcer, gynecological bleeding, headache, hypotension, jaundice, neutropenia, restless legs syndrome, stuttering ³, sudden unexpected death ⁴, sweating, and violent behaviors ³. Random triglyceride levels of ≥1000 mg/dL have been reported.

³ Stuttering was only studied in oral and long acting injection (LAI) olanzapine formulations

⁴ These terms represent serious adverse events but do not meet the definition for adverse drug reactions. They are included here because of their seriousness.

Children and Adolescent Patients (aged 10 to 17 years) with a Diagnosis of Bipolar Depression

The information below is derived from a single, 8 week, randomized, placebo-controlled clinical trial investigating olanzapine and fluoxetine capsules for the treatment of bipolar I depression in patients 10 to 17 years of age.

Adverse Reactions Associated with Discontinuation of Treatment in the single pediatric study — Overall, 14.1% of the 170 patients in the olanzapine and fluoxetine capsule group discontinued due to adverse reactions compared with 5.9% of the 85 patients for placebo. Adverse reactions leading to discontinuation associated with the use of olanzapine and fluoxetine capsules (incidence of at least 1% for olanzapine and fluoxetine capsules and greater than that for placebo) using MedDRA Dictionary coding were weight increased (2.9%), suicidal ideation (1.8%), bipolar disorder (1.2%), and somnolence (1.2%) versus placebo patients which had 0% incidence of weight increased, bipolar disorder, and somnolence, and a 1.2% incidence of suicidal ideation.

Adverse Reactions Occurring at an Incidence of 2% or more and greater than placebo — Table 17 enumerates the treatment-emergent adverse reactions associated with the use of olanzapine and fluoxetine capsules (incidence of at least 2% for olanzapine and fluoxetine capsules and twice or more than for placebo).

^a Includes somnolence, sedation, and hypersomnia. No lethargy was reported.

^b Includes alanine aminotransferase increased, aspartate aminotransferase increased, hepatic enzyme increased, liver function test
  abnormal, gamma-glutamyltransferase increased, and transaminases increased.

Adults:

Vital Signs — Tachycardia, bradycardia, and orthostatic hypotension have occurred in olanzapine and fluoxetine capsule-treated patients [ see Warnings and Precautions (5.11)]. The mean standing pulse rate of olanzapine and fluoxetine capsule-treated patients was reduced by 0.7 beats/min.

Laboratory Changes — In olanzapine and fluoxetine capsule clinical studies (including treatment resistant depression, depressive episodes associated with Bipolar I Disorder, Major Depressive Disorder with psychosis, or sexual dysfunction), olanzapine and fluoxetine capsules were associated with statistically significantly greater frequencies for the following treatment-emergent findings in laboratory analytes (normal at baseline to abnormal at any time during the trial) compared to placebo: elevated prolactin (28% vs 5%); elevated urea nitrogen (3% vs 0.8%); elevated uric acid (3% vs 0.5%); low albumin (3% vs 0.3%); low bicarbonate (14% vs 9%); low hemoglobin (3% vs 0%); low inorganic phosphorus (2% vs 0.3%); low lymphocytes (2% vs 0%); and low total bilirubin (15% vs 4%).

As with olanzapine, asymptomatic elevations of hepatic aminotransferases [ALT, AST, and GGT] and alkaline phosphatase have been observed with olanzapine and fluoxetine capsules. In the olanzapine and fluoxetine capsule-controlled database, clinically significant ALT elevations (change from <3 times the upper limit of normal [ULN] at baseline to ≥3 times ULN) were observed in 5% (38/698) of patients exposed to olanzapine and fluoxetine capsules compared with 0.5% (2/378) of placebo-treated patients and 4% (33/751) of olanzapine-treated patients. ALT elevations ≥5 times ULN were observed in 2% (11/701) of olanzapine and fluoxetine capsule-treated patients, compared to 0.3% (1/379) of placebo-treated patients and 1% (11/760) of olanzapine-treated patients. No patient with elevated ALT values experienced jaundice or liver failure, or met the criteria for Hy's Rule. ALT values returned to normal, or were decreasing, at last follow-up in the majority of patients who either continued treatment with olanzapine and fluoxetine capsules or discontinued olanzapine and fluoxetine capsules.

Rare postmarketing reports of hepatitis have been received in patients treated with olanzapine. Very rare cases of cholestatic or mixed liver injury have also been reported in the postmarketing period in patients treated with olanzapine.

Caution should be exercised in patients with signs and symptoms of hepatic impairment, in patients with pre-existing conditions associated with limited hepatic functional reserve, and in patients who are being treated with potentially hepatotoxic drugs.

An increase in creatine phosphokinase has been reported very rarely in olanzapine and fluoxetine capsule-treated patients and infrequently in clinical trials of olanzapine-treated patients.

QT Interval Prolongation — In patients treated with olanzapine and fluoxetine capsules QT _cF≥450 msec for males and QT _cF≥470 msec for females has been reported frequently (≥1%). The incidence of QT _cF>500 msec associated with olanzapine and fluoxetine capsule treatment in clinical trials has been rare and was not significantly different from the incidence associated with placebo. The mean increase in QT _c interval for olanzapine and fluoxetine capsule-treated patients (5.17 msec) in the one clinical study directly comparing olanzapine and fluoxetine capsules to placebo in adult patients was significantly greater than that for placebo-treated patients (-1.66 msec).

Children and Adolescents (aged 10 to 17 years):

In a single 8 week randomized, placebo-controlled clinical trial investigating olanzapine and fluoxetine capsules for treatment of bipolar I depression in patients 10 to 17 years of age, the following was observed:

Vital Signs — In the olanzapine and fluoxetine capsule-treated patients compared with placebo-treated patients, the mean orthostatic blood pressure and standing pulse rate were not significantly different between treatment groups.

Body Weight: An increase in weight greater than or equal to 7% occurred in 52.4% of the olanzapine and fluoxetine capsule group and 3.6% of the placebo group. Weight gain greater than or equal to 15% occurred in 14.1% of the olanzapine and fluoxetine capsule group and none of the placebo group.

Laboratory Changes — Olanzapine and fluoxetine capsules were associated with statistically significantly greater frequencies for the following treatment-emergent findings in laboratory analytes (normal or low at baseline to abnormal at any time during the trial) compared to placebo: elevated ALT (45.9% vs 2.5%); elevated AST (33.7% vs 7.6%); high fasting total cholesterol (28.9% vs 8.2%); high fasting LDL cholesterol (19.7% vs 6.5%); high fasting triglycerides (52.3% vs 27.3%), and elevated prolactin (85% vs 36%). No patient with elevated hepatic enzyme values experienced jaundice or liver failure, or met the criteria for Hy’s Rule. Five patients experienced an adverse event potentially associated with elevated prolactin; these events included dysmenorrhoea, galactorrhoea, and ovulation disorder.

QT Interval Prolongation — Olanzapine and fluoxetine capsules were associated with a statistically significantly greater mean increase in QT _cF interval (8.2 msec [95% CI 6.2, 10.2]) compared with placebo. No patients developed QT _c increases ≥60 msec or QT _c ≥480 msec [ see Warnings and Precautions (5.20)].

The following adverse reactions have been identified during post-approval use of olanzapine and fluoxetine capsules. Because these reactions are reported voluntarily from a population of uncertain size, it is difficult to reliably estimate their frequency or evaluate a causal relationship to drug exposure.

Adverse reactions reported since market introduction that were temporally (but not necessarily causally) related to olanzapine and fluoxetine capsule therapy include the following: rhabdomyolysis and venous thromboembolic events (including pulmonary embolism and deep venous thrombosis).

The risks of using olanzapine and fluoxetine capsules in combination with other drugs have not been extensively evaluated in systematic studies. The drug-drug interactions sections of fluoxetine and olanzapine are applicable to olanzapine and fluoxetine capsules. As with all drugs, the potential for interaction by a variety of mechanisms (e.g., pharmacodynamic, pharmacokinetic drug inhibition or enhancement, etc.) is a possibility. In evaluating individual cases, consideration should be given to using lower initial doses of the concomitantly administered drugs, using conservative titration schedules, and monitoring of clinical status [see Clinical Pharmacology (12.3)].

[ See Dosage and Administration ( 2.4, 2.5), Contraindications ( 4.1), and Warnings and Precautions ( 5.6) ].

Caution is advised if the concomitant administration of olanzapine and fluoxetine capsules and other CNS-active drugs is required. In evaluating individual cases, consideration should be given to using lower initial doses of the concomitantly administered drugs, using conservative titration schedules, and monitoring of clinical status [ see Clinical Pharmacology ( 12.3) ].

[ See Dosage and Administration ( 2.4, 2.5), Contraindications ( 4.1), and Warnings and Precautions ( 5.6) ].

Serotonin release by platelets plays an important role in hemostasis. Epidemiological studies of the case-control and cohort design that have demonstrated an association between use of psychotropic drugs that interfere with serotonin reuptake and the occurrence of upper gastrointestinal bleeding have also shown that concurrent use of an NSAID or aspirin may potentiate this risk of bleeding. Altered anticoagulant effects, including increased bleeding, have been reported when SNRIs or SSRIs are coadministered with warfarin [ see Warnings and Precautions (5.16)]. Warfarin (20 mg single dose) did not affect olanzapine pharmacokinetics. Single doses of olanzapine did not affect the pharmacokinetics of warfarin. Patients receiving warfarin therapy should be carefully monitored when olanzapine and fluoxetine capsules are initiated or discontinued.

There are no clinical studies establishing the benefit of the combined use of ECT and fluoxetine. There have been rare reports of prolonged seizures in patients on fluoxetine receiving ECT treatment [ see Warnings and Precautions (5.15)].

Benzodiazepines — Coadministration of diazepam with olanzapine potentiated the orthostatic hypotension observed with olanzapine [ see Drug Interactions ( 7.7) ].

Inducers of 1A2 — Carbamazepine therapy (200 mg BID) causes an approximate 50% increase in the clearance of olanzapine. This increase is likely due to the fact that carbamazepine is a potent inducer of CYP1A2 activity. Higher daily doses of carbamazepine may cause an even greater increase in olanzapine clearance [ see Drug Interactions ( 7.7) ].

Alcohol — Ethanol (45 mg/70 kg single dose) did not have an effect on olanzapine pharmacokinetics [ see Drug Interactions ( 7.7) ].

Inhibitors of CYP1A2 — Fluvoxamine decreases the clearance of olanzapine. This results in a mean increase in olanzapine C _max following fluvoxamine administration of 54% in female nonsmokers and 77% in male smokers. The mean increase in olanzapine AUC is 52% and 108%, respectively. Lower doses of the olanzapine component of olanzapine and fluoxetine capsules should be considered in patients receiving concomitant treatment with fluvoxamine.

The Effect of Other Drugs on Olanzapine — Fluoxetine, an inhibitor of CYP2D6, decreases olanzapine clearance a small amount [ see Clinical Pharmacology ( 12.3) ]. Agents that induce CYP1A2 or glucuronyl transferase enzymes, such as omeprazole and rifampin, may cause an increase in olanzapine clearance. The effect of CYP1A2 inhibitors, such as fluvoxamine and some fluoroquinolone antibiotics, on olanzapine and fluoxetine capsules has not been evaluated. Although olanzapine is metabolized by multiple enzyme systems, induction or inhibition of a single enzyme may appreciably alter olanzapine clearance. Therefore, a dosage increase (for induction) or a dosage decrease (for inhibition) may need to be considered with specific drugs.

Pimozide — Concomitant use of olanzapine and fluoxetine capsules and pimozide is contraindicated. Pimozide can prolong the QT interval. Olanzapine and fluoxetine capsules can increase the level of pimozide through inhibition of CYP2D6. Olanzapine and fluoxetine capsules can also prolong the QT interval. Clinical studies of pimozide with other antidepressants demonstrate an increase in drug interaction or QT _c prolongation. While a specific study with pimozide and olanzapine and fluoxetine capsules has not been conducted, the potential for drug interactions or QT _c prolongation warrants restricting the concurrent use of pimozide and olanzapine and fluoxetine capsules [ see Contraindications ( 4.2), Warnings and Precautions ( 5.20), and Drug Interactions ( 7.8) ].

Carbamazepine — Patients on stable doses of carbamazepine have developed elevated plasma anticonvulsant concentrations and clinical anticonvulsant toxicity following initiation of concomitant fluoxetine treatment.

Alcohol — The coadministration of ethanol with olanzapine and fluoxetine capsules may potentiate sedation and orthostatic hypotension [ see Drug Interactions ( 7.6) ].

Thioridazine — Thioridazine should not be administered with olanzapine and fluoxetine capsules or administered within a minimum of 5 weeks after discontinuation of olanzapine and fluoxetine capsules because of the risk of QT prolongation [ see Contraindications ( 4.2), Warnings and Precautions ( 5.20), and Drug Interactions ( 7.8) ].

In a study of 19 healthy male subjects, which included 6 slow and 13 rapid hydroxylators of debrisoquin, a single 25 mg oral dose of thioridazine produced a 2.4-fold higher C _max and a 4.5-fold higher AUC for thioridazine in the slow hydroxylators compared with the rapid hydroxylators. The rate of debrisoquin hydroxylation is felt to depend on the level of CYP2D6 isozyme activity. Thus, this study suggests that drugs that inhibit CYP2D6, such as certain SSRIs, including fluoxetine, will produce elevated plasma levels of thioridazine [ see Contraindications ( 4.2) ].

Thioridazine administration produces a dose-related prolongation of the QT _c interval, which is associated with serious ventricular arrhythmias, such as torsade de pointes-type arrhythmias and sudden death. This risk is expected to increase with fluoxetine-induced inhibition of thioridazine metabolism [ see Contraindications ( 4.2) ].

Due to the risk of serious ventricular arrhythmias and sudden death potentially associated with elevated thioridazine plasma levels, thioridazine should not be administered with fluoxetine or within a minimum of 5 weeks after fluoxetine has been discontinued [ see Contraindications ( 4.2) ].

Tricyclic Antidepressants (TCAs) — Single doses of olanzapine did not affect the pharmacokinetics of imipramine or its active metabolite desipramine.

In 2 fluoxetine studies, previously stable plasma levels of imipramine and desipramine have increased >2- to 10-fold when fluoxetine has been administered in combination. This influence may persist for 3 weeks or longer after fluoxetine is discontinued. Thus, the dose of TCA may need to be reduced and plasma TCA concentrations may need to be monitored temporarily when olanzapine and fluoxetine capsules are coadministered or has been recently discontinued [ see Warnings and Precautions ( 5.6) and Clinical Pharmacology ( 12.3) ].

Antihypertensive Agents — Because of the potential for olanzapine to induce hypotension, olanzapine and fluoxetine capsules may enhance the effects of certain antihypertensive agents [ see Warnings and Precautions (5.11)].

Levodopa and Dopamine Agonists — The olanzapine component of olanzapine and fluoxetine capsules may antagonize the effects of levodopa and dopamine agonists.

Benzodiazepines — Multiple doses of olanzapine did not influence the pharmacokinetics of diazepam and its active metabolite N-desmethyldiazepam.

When concurrently administered with fluoxetine, the half-life of diazepam may be prolonged in some patients [ see Clinical Pharmacology ( 12.3) ]. Coadministration of alprazolam and fluoxetine has resulted in increased alprazolam plasma concentrations and in further psychomotor performance decrement due to increased alprazolam levels.

Clozapine — Elevation of blood levels of clozapine has been observed in patients receiving concomitant fluoxetine.

Haloperidol — Elevation of blood levels of haloperidol has been observed in patients receiving concomitant fluoxetine.

Phenytoin — Patients on stable doses of phenytoin have developed elevated plasma levels of phenytoin with clinical phenytoin toxicity following initiation of concomitant fluoxetine.

Drugs Metabolized by CYP2D6 — In vitro studies utilizing human liver microsomes suggest that olanzapine has little potential to inhibit CYP2D6. Thus, olanzapine is unlikely to cause clinically important drug interactions mediated by this enzyme.

Fluoxetine inhibits the activity of CYP2D6 and may make individuals with normal CYP2D6 metabolic activity resemble a poor metabolizer. Coadministration of fluoxetine with other drugs that are metabolized by CYP2D6, including certain antidepressants (e.g., TCAs), antipsychotics (e.g., phenothiazines and most atypicals), and antiarrhythmics (e.g., propafenone, flecainide, and others) should be approached with caution. Therapy with medications that are predominantly metabolized by the CYP2D6 system and that have a relatively narrow therapeutic index should be initiated at the low end of the dose range if a patient is receiving fluoxetine concurrently or has taken it in the previous 5 weeks. If fluoxetine is added to the treatment regimen of a patient already receiving a drug metabolized by CYP2D6, the need for a decreased dose of the original medication should be considered. Drugs with a narrow therapeutic index represent the greatest concern (including but not limited to, flecainide, propafenone, vinblastine, and TCAs).

Drugs Metabolized by CYP3A — In vitro studies utilizing human liver microsomes suggest that olanzapine has little potential to inhibit CYP3A. Thus, olanzapine is unlikely to cause clinically important drug interactions mediated by these enzymes.

In an in vivo interaction study involving the coadministration of fluoxetine with single doses of terfenadine (a CYP3A substrate), no increase in plasma terfenadine concentrations occurred with concomitant fluoxetine. In addition, in vitro studies have shown ketoconazole, a potent inhibitor of CYP3A activity, to be at least 100 times more potent than fluoxetine or norfluoxetine as an inhibitor of the metabolism of several substrates for this enzyme, including astemizole, cisapride, and midazolam. These data indicate that fluoxetine’s extent of inhibition of CYP3A activity is not likely to be of clinical significance.

Effect of Olanzapine on Drugs Metabolized by Other CYP Enzymes — In vitro studies utilizing human liver microsomes suggest that olanzapine has little potential to inhibit CYP1A2, CYP2C9, and CYP2C19. Thus, olanzapine is unlikely to cause clinically important drug interactions mediated by these enzymes.

Lithium — Multiple doses of olanzapine did not influence the pharmacokinetics of lithium.

There have been reports of both increased and decreased lithium levels when lithium was used concomitantly with fluoxetine. Cases of lithium toxicity and increased serotonergic effects have been reported. Lithium levels should be monitored in patients taking olanzapine and fluoxetine capsules concomitantly with lithium [ see Warnings and Precautions ( 5.5) ].

Drugs Tightly Bound to Plasma Proteins — The in vitro binding of olanzapine and fluoxetine capsules to human plasma proteins is similar to the individual components. The interaction between olanzapine and fluoxetine capsules and other highly protein-bound drugs has not been fully evaluated. Because fluoxetine is tightly bound to plasma protein, the administration of fluoxetine to a patient taking another drug that is tightly bound to protein (e.g., warfarin, digitoxin) may cause a shift in plasma concentrations potentially resulting in an adverse effect. Conversely, adverse effects may result from displacement of protein-bound fluoxetine by other tightly bound drugs [ see Clinical Pharmacology ( 12.3) ].

Valproate — In vitro studies using human liver microsomes determined that olanzapine has little potential to inhibit the major metabolic pathway, glucuronidation, of valproate. Further, valproate has little effect on the metabolism of olanzapine in vitro. Thus, a clinically significant pharmacokinetic interaction between olanzapine and valproate is unlikely.

Biperiden — Multiple doses of olanzapine did not influence the pharmacokinetics of biperiden.

Theophylline — Multiple doses of olanzapine did not affect the pharmacokinetics of theophylline or its metabolites.

Do not use olanzapine and fluoxetine capsules in combination with thioridazine or pimozide. Use olanzapine and fluoxetine capsules with caution in combination with other drugs that cause QT prolongation. These include: specific antipsychotics (e.g., ziprasidone, iloperidone, chlorpromazine, mesoridazine, droperidol); specific antibiotics (e.g., erythromycin, gatifloxacin, moxifloxacin, sparfloxacin); Class 1A antiarrhythmic medications (e.g., quinidine, procainamide); Class III antiarrhythmics (e.g., amiodarone, sotalol); and others (e.g., pentamidine, levomethadyl acetate, methadone, halofantrine, mefloquine, dolasetron mesylate, probucol or tacrolimus). Fluoxetine is primarily metabolized by CYP2D6. Concomitant treatment with CYP2D6 inhibitors can increase the concentration of fluoxetine. Concomitant use of other highly protein-bound drugs can increase the concentration of fluoxetine [ see Contraindications ( 4.2), Warnings and Precautions ( 5.20), Drug Interactions ( 7.7), and Clinical Pharmacology ( 12.3) ].

There are no adequate and well-controlled clinical studies with olanzapine and fluoxetine capsules or their components (olanzapine and fluoxetine) in pregnant women.

A number of published epidemiological studies assessing the risk of fluoxetine exposure during the first trimester of pregnancy have demonstrated inconsistent results.

Neonates exposed to fluoxetine, a component of olanzapine and fluoxetine capsules, and other SSRIs and SNRIs late in the third trimester have developed complications arising immediately upon delivery (respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying) requiring prolonged hospitalization, respiratory support, and tube feeding. These features are consistent with either a direct toxic effect of SSRIs and SNRIs or, possibly, a drug discontinuation syndrome. In some cases, the clinical picture is consistent with serotonin syndrome. Neonates exposed to olanzapine, a component of olanzapine and fluoxetine capsules, during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and feeding disorder. These complications have varied in severity; while in some cases symptoms have been self-limited, in other cases neonates have required intensive care unit support and prolonged hospitalization.

Infants exposed to SSRIs in pregnancy may have an increased risk for persistent pulmonary hypertension of the newborn (PPHN).

Olanzapine and fluoxetine capsules should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus, taking into account the risk of untreated Bipolar I Depression or Treatment Resistant Depression.

There are no adequate and well-controlled clinical studies with olanzapine and fluoxetine capsules, olanzapine or fluoxetine in pregnant women. Seven pregnancies were observed during premarketing clinical studies with olanzapine, including 2 resulting in normal births, 1 resulting in neonatal death due to a cardiovascular defect, 3 therapeutic abortions, and 1 spontaneous abortion. Results of a number of published epidemiological studies assessing the risk of fluoxetine exposure during the first trimester of pregnancy have demonstrated inconsistent results. More than 10 cohort studies and case-control studies failed to demonstrate an increased risk for congenital malformations overall. However, one prospective cohort study conducted by the European Network of Teratology Information Services reported an increased risk of cardiovascular malformations in infants born to women (N = 253) exposed to fluoxetine during the first trimester of pregnancy compared to infants of women (N = 1359) who were not exposed to fluoxetine. There was no specific pattern of cardiovascular malformations. Overall, however, a causal relationship has not been established.

Neonates exposed to fluoxetine, a component of olanzapine and fluoxetine capsules, and other SSRIs or serotonin and norepinephrine reuptake inhibitors (SNRIs), late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding. Such complications can arise immediately upon delivery. Reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying. These features are consistent with either a direct toxic effect of SSRIs and SNRIs or, possibly, a drug discontinuation syndrome. It should be noted that, in some cases, the clinical picture is consistent with serotonin syndrome [ see Dosage and Administration ( 2.3) and Warnings and Precautions ( 5.6) ].

Infants exposed to SSRIs in pregnancy may have an increased risk for persistent pulmonary hypertension of the newborn (PPHN). PPHN occurs in 1 to 2 per 1,000 live births in the general population and is associated with substantial neonatal morbidity and mortality. Several recent epidemiologic studies suggest a positive statistical association between SSRI (including fluoxetine) use in pregnancy and PPHN. Other studies do not show a significant statistical association.

Neonates exposed to antipsychotic drugs (including olanzapine, a component of olanzapine and fluoxetine capsules), during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery. There have been reports of agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and feeding disorder in these neonates. These complications have varied in severity; while in some cases symptoms have been self-limited, in other cases neonates have required intensive care unit support and prolonged hospitalization.

Physicians should also note the results of a prospective longitudinal study of 201 pregnant women with a history of major depression, who were either on antidepressants or had received antidepressants less than 12 weeks prior to their last menstrual period, and were in remission. Women who discontinued antidepressant medication during pregnancy showed a significant increase in relapse of their major depression compared to those women who remained on antidepressant medication throughout pregnancy.

When treating a pregnant woman with olanzapine and fluoxetine capsules, the physician should carefully consider both the potential risks of taking an SSRI, along with the established benefits of treating depression with an antidepressant. This decision can only be made on a case by case basis [ see Dosage and Administration ( 2.3) ].

Olanzapine and fluoxetine capsules should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Olanzapine and fluoxetine capsules — Embryo fetal development studies were conducted in rats and rabbits with olanzapine and fluoxetine in low-dose and high-dose combinations. In rats, the doses were: 2 and 4 mg/kg/day (low-dose) [1 and 0.5 times the maximum recommended human dose (MRHD) for olanzapine (20 mg) and fluoxetine (80 mg), respectively on a mg/m ² body surface area], and 4 and 8 mg/kg/day (high-dose) [2 and 1 times the MRHD on a mg/m ² body surface area, respectively]. In rabbits, the doses were 4 and 4 mg/kg/day (low-dose) [4 and 1 times the MRHD on a mg/m ² basis, respectively], and 8 and 8 mg/kg/day (high-dose) [9 and 2 times the MRHD on a mg/m ² basis, respectively]. In these studies, olanzapine and fluoxetine were also administered alone at the high-doses (4 and 8 mg/kg/day, respectively, in the rat; 8 and 8 mg/kg/day, respectively, in the rabbit). In the rabbit, there was no evidence of teratogenicity; however, the high-dose combination produced decreases in fetal weight and retarded skeletal ossification in conjunction with maternal toxicity. Similarly, in the rat there was no evidence of teratogenicity; however, a decrease in fetal weight was observed with the high-dose combination.

In a pre- and postnatal study conducted in rats, olanzapine and fluoxetine were orally administered during pregnancy and throughout lactation in combination at dose levels up to 2 (olanzapine) plus 4 (fluoxetine) mg/kg/day (1 and 0.5 times the MRHD on a mg/m ² body surface area. An elevation of early postnatal mortality (survival through postnatal day 4 was 69% per litter) and reduced bodyweight (approximately 8% in female) occurred among offspring at the highest dose: the no-effect dose was 0.5 (olanzapine) plus 1 (fluoxetine) mg/kg/day (0.25 and 0.13 times the MRHD on a mg/m ² body surface area). Among the surviving progeny, there were no adverse effects on physical or neurobehavioral development and reproductive performance at any dose.

Olanzapine — In oral embryo-fetal studies in rats and rabbits, there was no evidence of teratogenicity following administration of olanzapine at doses up to 18 and 30 mg/kg/day, respectively (9 and 30 times the MRHD on a mg/m ² basis, respectively). In a rat teratology study, early resorptions and increased numbers of dead fetuses were observed at a dose of 18 mg/kg/day (9 times the MRHD on a mg/m ² basis). Gestation was prolonged at 10 mg/kg/day (5 times the MRHD on a mg/m ² basis). In a rabbit teratology study, fetal toxicity (manifested as increased resorptions and decreased fetal weight) occurred at a maternally toxic dose of 30 mg/kg/day (30 times the MRHD on a mg/m ² basis). Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Placental transfer of olanzapine occurs in rat pups.

Fluoxetine — In oral embryo-fetal development studies in rats and rabbits, there was no evidence of teratogenicity following administration of fluoxetine at doses up to 12.5 and 15 mg/kg/day, respectively (1.5 and 3.6 times, respectively, the MRHD of 80 mg/day on a mg/m ² basis) throughout organogenesis. However, in rat reproduction studies, an increase in stillborn pups, a decrease in pup weight, and an increase in pup deaths during the first 7 days postpartum occurred following maternal exposure to 12 mg/kg/day (1.5 times the MRHD on a mg/m ² basis) during gestation or 7.5 mg/kg/day (0.9 times the MRHD on a mg/m ² basis) during gestation and lactation. There was no evidence of developmental neurotoxicity in the surviving offspring of rats treated with 12 mg/kg/day during gestation. The no-effect dose for rat pup mortality was 5 mg/kg/day (0.6 times the MRHD on a mg/m ² basis).

Olanzapine and fluoxetine capsules — The effect of olanzapine and fluoxetine capsules on labor and delivery in humans is unknown. Parturition in rats was not affected by olanzapine and fluoxetine capsules. Olanzapine and fluoxetine capsules should be used during labor and delivery only if the potential benefit justifies the potential risk.

Olanzapine — The effect of olanzapine on labor and delivery in humans is unknown. Parturition in rats was not affected by olanzapine.

Fluoxetine — The effect of fluoxetine on labor and delivery in humans is unknown. Fluoxetine crosses the placenta; therefore, there is a possibility that fluoxetine may be associated with adverse effects on the newborn.

Olanzapine and fluoxetine capsules — Studies evaluating the individual components of olanzapine and fluoxetine capsules (olanzapine and fluoxetine) in nursing mothers are described below. Because of the potential for serious adverse reactions in nursing infants from olanzapine and fluoxetine capsules, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother. It is recommended that women not breast-feed when receiving olanzapine and fluoxetine capsules.

Olanzapine — In a study in lactating, healthy women, olanzapine was excreted in breast milk. Mean infant dose at steady state was estimated to be 1.8% of the maternal olanzapine dose. It is recommended that women receiving olanzapine should not breast-feed.

Fluoxetine — Fluoxetine is excreted in human breast milk. In 1 breast milk sample, the concentration of fluoxetine plus norfluoxetine was 70.4 ng/mL. The concentration in the mother’s plasma was 295.0 ng/mL. No adverse effects on the infant were reported. In another case, an infant nursed by a mother on fluoxetine developed crying, sleep disturbance, vomiting, and watery stools. The infant’s plasma drug levels were 340 ng/mL of fluoxetine and 208 ng/mL of norfluoxetine on the 2nd day of feeding.

Olanzapine and fluoxetine capsules — The safety and efficacy of olanzapine and fluoxetine capsules in patients 10 to 17 years of age has been established for the acute treatment of Depressive Episodes Associated with Bipolar I Disorder in a single 8 week randomized, placebo-controlled clinical trial (N = 255) [ see Clinical Studies ( 14.1) ]. Patients were initiated at a dose of 3/25 mg/day and force-titrated to the maximum dose of 12/50 mg/day over two weeks. After Week 2, there was flexible dosing of olanzapine and fluoxetine capsules in the range of 6/25, 6/50, 12/25, or 12/50 mg/day. The average dose was olanzapine 7.7 mg and fluoxetine 37.6 mg. The recommended starting dose for children and adolescents is 3/25 mg per day (lower than that for adults). Flexible dosing is recommended, rather than the forced titration used in the study [ see Dosage and Administration ( 2.1) ].

The types of adverse events observed with olanzapine and fluoxetine capsules in children and adolescents were generally similar to those observed in adults. However, the magnitude and frequency of some changes were greater in children and adolescents than adults. These included increases in lipids, hepatic enzymes, and prolactin, as well as increases in the QT interval [ see Warnings and Precautions ( 5.5, 5.20, 5.22), and Vital Signs and Laboratory Studies ( 6.2) ]. The frequency of weight gain ≥7%, and the magnitude and frequency of increases in lipids, hepatic analytes, and prolactin in children and adolescents treated with olanzapine and fluoxetine capsules were similar to those observed in adolescents treated with olanzapine monotherapy.

The safety and efficacy of olanzapine and fluoxetine in combination for the treatment of bipolar I depression in patients under the age of 10 years have not been established. The safety and effectiveness of olanzapine and fluoxetine in combination for treatment resistant depression in patients less than 18 years of age have not been established.

Anyone considering the use of olanzapine and fluoxetine capsules in a child or adolescent must balance the potential risks with the clinical need [ see Boxed Warning and Warnings and Precautions ( 5.1) ].

Olanzapine — Safety and effectiveness of olanzapine in children <13 years of age have not been established.

Compared to patients from adult clinical trials, adolescents treated with oral olanzapine were likely to gain more weight, experience increased sedation, and have greater increases in total cholesterol, triglycerides, LDL cholesterol, prolactin and hepatic aminotransferase levels.

Animal Data

Fluoxetine — Juvenile animal toxicity studies were performed for fluoxetine alone. Significant toxicity on muscle tissue, neurobehavior, reproductive organs, and bone development has been observed following exposure of juvenile rats to fluoxetine from weaning through maturity. Oral administration of fluoxetine to rats from weaning postnatal day 21 through adulthood day 90 at 3, 10, or 30 mg/kg/day was associated with testicular degeneration and necrosis, epididymal vacuolation and hypospermia (at 30 mg/kg/day corresponding to plasma exposures [AUC] approximately 5 to 10 times the average AUC in pediatric patients at the MRHD of 20 mg/day), increased serum levels of creatine kinase (at AUC as low as 1 to 2 times the average AUC in pediatric patients at the MRHD of 20 mg/day), skeletal muscle degeneration and necrosis, decreased femur length/growth and body weight gain (at AUC 5 to 10 times the average AUC in pediatric patients at the MRHD of 20 mg/day). The high dose of 30 mg/kg/day exceeded a maximum tolerated dose. When animals were evaluated after a drug-free period (up to 11 weeks after cessation of dosing), fluoxetine was associated with neurobehavioral abnormalities (decreased reactivity at AUC as low as approximately 0.1 to 0.2 times the average AUC in pediatric patients at the MRHD and learning deficit at the high dose), and reproductive functional impairment (decreased mating at all doses and impaired fertility at the high dose). In addition, the testicular and epididymal microscopic lesions and decreased sperm concentrations found in high dose group were also observed, indicating that the drug effects on reproductive organs are irreversible. The reversibility of fluoxetine-induced muscle damage was not assessed.

These fluoxetine toxicities in juvenile rats have not been observed in adult animals. Plasma exposures (AUC) to fluoxetine in juvenile rats receiving 3, 10, or 30 mg/kg/day doses in this study are approximately 0.1 to 0.2, 1 to 2, and 5 to 10 times, respectively, the average exposure in pediatric patients receiving the MRHD of 20 mg/day. Rat exposures to the major metabolite, norfluoxetine, are approximately 0.3 to 0.8, 1 to 8, and 3 to 20 times, respectively, the pediatric exposure at the MRHD.

A specific effect on bone development was reported in juvenile mice administered fluoxetine by the intraperitoneal route to 4 week old mice for 4 weeks at doses 0.5 and 2 times the oral MRHD of 20 mg/day on mg/m ² basis. There was a decrease in bone mineralization and density at both doses, but the overall growth (body weight gain or femur length) was not affected.

Olanzapine and fluoxetine capsules — Clinical studies of olanzapine and fluoxetine capsules did not include sufficient numbers of patients ≥65 years of age to determine whether they respond differently from younger patients. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy [ see Dosage and Administration ( 2.3) ].

Olanzapine — Of the 2500 patients in premarketing clinical studies with olanzapine, 11% (263 patients) were ≥65 years of age. In patients with Schizophrenia, there was no indication of any different tolerability of olanzapine in the elderly compared with younger patients. Studies in patients with dementia-related psychosis have suggested that there may be a different tolerability profile in this population compared with younger patients with Schizophrenia. Elderly patients with dementia-related psychosis treated with olanzapine are at an increased risk of death compared to placebo. In placebo-controlled studies of olanzapine in elderly patients with dementia-related psychosis, there was a higher incidence of cerebrovascular adverse reactions (e.g., stroke, transient ischemic attack) in patients treated with olanzapine compared to patients treated with placebo. Olanzapine is not approved for the treatment of patients with dementia-related psychosis [ see Boxed Warning, Dosage and Administration ( 2.3), and Warnings and Precautions ( 5.2) ].

Also, the presence of factors that might decrease pharmacokinetic clearance or increase the pharmacodynamic response to olanzapine should lead to consideration of a lower starting dose for any geriatric patient.

Fluoxetine — U.S. fluoxetine clinical studies included 687 patients ≥65 years of age and 93 patients ≥75 years of age. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. SNRIs and SSRIs, including olanzapine and fluoxetine capsules, have been associated with cases of clinically significant hyponatremia in elderly patients, who may be at greater risk for this adverse reaction [ see Warnings and Precautions (5.17)].

In subjects with cirrhosis of the liver, the clearances of fluoxetine and its active metabolite, norfluoxetine, were decreased, thus increasing the elimination half-lives of these substances. A lower or less frequent dose of the fluoxetine-component of olanzapine and fluoxetine capsules should be used in patients with cirrhosis. Caution is advised when using olanzapine and fluoxetine capsules in patients with diseases or conditions that could affect its metabolism [ see Dosage and Administration ( 2.3) and Clinical Pharmacology ( 12.4) ].

Olanzapine and fluoxetine capsules, as with fluoxetine and olanzapine, have not been systematically studied in humans for their potential for abuse, tolerance, or physical dependence. While the clinical studies did not reveal any tendency for any drug-seeking behavior, these observations were not systematic, and it is not possible to predict on the basis of this limited experience the extent to which a CNS-active drug will be misused, diverted, and/or abused once marketed. Consequently, physicians should carefully evaluate patients for history of drug abuse and follow such patients closely, observing them for signs of misuse or abuse of olanzapine and fluoxetine capsules (e.g., development of tolerance, incrementation of dose, drug-seeking behavior).

In studies in rats and rhesus monkeys designed to assess abuse and dependence potential, olanzapine alone was shown to have acute depressive CNS effects but little or no potential of abuse or physical dependence at oral doses up to 15 (rat) and 8 (monkey) times the MRHD (20 mg) on a mg/m ² basis.

Olanzapine and fluoxetine capsules — During premarketing clinical studies of olanzapine and fluoxetine in combination, overdose of both fluoxetine and olanzapine were reported in 5 study subjects. Four of the 5 subjects experienced loss of consciousness (3) or coma (1). No fatalities occurred.

Adverse reactions involving overdose of fluoxetine and olanzapine in combination, and olanzapine and fluoxetine capsules, have been reported. An overdose of combination therapy is defined as confirmed or suspected ingestion of a dose of >20 mg olanzapine in combination with a dose of >80 mg fluoxetine. Adverse reactions associated with these reports included somnolence (sedation), impaired consciousness (coma), impaired neurologic function (ataxia, confusion, convulsions, dysarthria), arrhythmias, lethargy, essential tremor, agitation, acute psychosis, hypotension, hypertension, and aggression. Fatalities have been confounded by exposure to additional substances including alcohol, thioridazine, oxycodone, and propoxyphene.

Olanzapine — In postmarketing reports of overdose with olanzapine alone, symptoms have been reported in the majority of cases. In symptomatic patients, symptoms with ≥10% incidence included agitation/aggressiveness, dysarthria, tachycardia, various extrapyramidal symptoms, and reduced level of consciousness ranging from sedation to coma. Among less commonly reported symptoms were the following potentially medically serious reactions: aspiration, cardiopulmonary arrest, cardiac arrhythmias (such as supraventricular tachycardia as well as a patient that experienced sinus pause with spontaneous resumption of normal rhythm), delirium, possible neuroleptic malignant syndrome, respiratory depression/arrest, convulsion, hypertension, and hypotension. Reports of fatality in association with overdose of olanzapine alone have been received. In 1 case of death, the amount of acutely ingested olanzapine was reported to be possibly as low as 450 mg of oral olanzapine; however, in another case, a patient was reported to survive an acute olanzapine ingestion of approximately 2 g of oral olanzapine.

Fluoxetine — Worldwide exposure to fluoxetine is estimated to be over 38 million patients (circa 1999). Of the 1578 cases of overdose involving fluoxetine, alone or with other drugs, reported from this population, there were 195 deaths.

Among 633 adult patients who overdosed on fluoxetine alone, 34 resulted in a fatal outcome, 378 completely recovered, and 15 patients experienced sequelae after overdose, including abnormal accommodation, abnormal gait, confusion, unresponsiveness, nervousness, pulmonary dysfunction, vertigo, tremor, elevated blood pressure, erectile dysfunction, movement disorder, and hypomania. The remaining 206 patients had an unknown outcome. The most common signs and symptoms associated with non-fatal overdose were seizures, somnolence, nausea, tachycardia, and vomiting. The largest known ingestion of fluoxetine in adult patients was 8 grams in a patient who took fluoxetine alone and who subsequently recovered. However, in an adult patient who took fluoxetine alone, an ingestion as low as 520 mg has been associated with lethal outcome, but causality has not been established.

Among pediatric patients (ages 3 months to 17 years), there were 156 cases of overdose involving fluoxetine alone or in combination with other drugs. Six patients died, 127 patients completely recovered, 1 patient experienced renal failure, and 22 patients had an unknown outcome. One of the 6 fatalities was a 9-year-old boy who had a history of OCD, Tourette’s Syndrome with tics, attention deficit disorder, and fetal alcohol syndrome. He had been receiving 100 mg of fluoxetine daily for 6 months in addition to clonidine, methylphenidate, and promethazine. Mixed-drug ingestion or other methods of suicide complicated all 6 overdoses in children that resulted in fatalities. The largest ingestion in pediatric patients was 3 grams, which was non-lethal.

Other important adverse reactions reported with fluoxetine overdose (single or multiple drugs) included coma, delirium, ECG abnormalities (such as nodal rhythm, QT-interval prolongation and ventricular arrhythmias, including torsade de pointes-type arrhythmias), hypotension, mania, neuroleptic malignant syndrome-like reactions, pyrexia, stupor, and syncope.

For current information on the management of olanzapine and fluoxetine capsules (olanzapine and fluoxetine) overdose, contact a certified poison control center (1-800-222-1222 or www.poison.org). In managing overdose, consider the possibility of multiple drug involvement. In case of acute overdose, establish and maintain an airway and ensure adequate ventilation, which may include intubation. Induction of emesis is not recommended as the possibility of obtundation, seizures, or dystonic reactions of the head and neck following overdose may create a risk for aspiration. Commence cardiovascular monitoring immediately and include continuous electrocardiographic monitoring to detect possible arrhythmias.

A specific precaution involves patients who are taking or have recently taken olanzapine and fluoxetine capsules and may have ingested excessive quantities of a TCA (tricyclic antidepressant). In such cases, accumulation of the parent TCA and/or an active metabolite increases the possibility of serious sequelae and extends the time needed for close medical observation.

Due to the large volume of distribution of olanzapine and fluoxetine, forced diuresis, dialysis, hemoperfusion, and exchange transfusion are unlikely to be of benefit. No specific antidote for either fluoxetine or olanzapine overdose is known. Treat hypotension and circulatory collapse with appropriate measures such as intravenous fluids and/or sympathomimetic agents. Do not use epinephrine, dopamine, or other sympathomimetics with β-agonist activity, since beta stimulation may worsen hypotension in the setting of olanzapine-induced alpha blockade.

Although the exact mechanism of olanzapine and fluoxetine capsules is unknown, it has been proposed that the activation of 3 monoaminergic neural systems (serotonin, norepinephrine, and dopamine) is responsible for its enhanced antidepressant effect. In animal studies, olanzapine and fluoxetine in combination has been shown to produce synergistic increases in norepinephrine and dopamine release in the prefrontal cortex compared with either component alone, as well as increases in serotonin.

Olanzapine binds with high affinity to the following receptors: serotonin 5HT _2A/2C, 5HT ₆ (K _i=4, 11, and 5 nM, respectively), dopamine D _1-4 (K _i=11 to 31 nM), histamine H ₁ (K _i=7 nM), and adrenergic α ₁ receptors (K _i=19 nM). Olanzapine is an antagonist with moderate affinity binding for serotonin 5HT ₃ (K _i=57 nM) and muscarinic M _1-5 (K _i=73, 96, 132, 32, and 48 nM, respectively). Olanzapine binds weakly to GABA _A, BZD, and β-adrenergic receptors (K _i >10 μM). Fluoxetine is an inhibitor of the serotonin transporter and is a weak inhibitor of the norepinephrine and dopamine transporters.

Antagonism at receptors other than dopamine and 5HT ₂ may explain some of the other therapeutic and side effects of olanzapine. Olanzapine’s antagonism of muscarinic M _1-5 receptors may explain its anticholinergic-like effects. The antagonism of histamine H ₁ receptors by olanzapine may explain the somnolence observed with this drug. The antagonism of α ₁-adrenergic receptors by olanzapine may explain the orthostatic hypotension observed with this drug. Fluoxetine has relatively low affinity for muscarinic, α ₁-adrenergic, and histamine H ₁ receptors.

Olanzapine and fluoxetine capsules — Fluoxetine (administered as a 60 mg single dose or 60 mg daily for 8 days) caused a small increase in the mean maximum concentration of olanzapine (16%) following a 5 mg dose, an increase in the mean area under the curve (17%) and a small decrease in mean apparent clearance of olanzapine (16%). In another study, a similar decrease in apparent clearance of olanzapine of 14% was observed following olanzapine doses of 6 or 12 mg with concomitant fluoxetine doses of 25 mg or more. The decrease in clearance reflects an increase in bioavailability. The terminal half-life is not affected, and therefore the time to reach steady state should not be altered. The overall steady-state plasma concentrations of olanzapine and fluoxetine when given as the combination in the therapeutic dose ranges were comparable with those typically attained with each of the monotherapies. The small change in olanzapine clearance, observed in both studies, likely reflects the inhibition of a minor metabolic pathway for olanzapine via CYP2D6 by fluoxetine, a potent CYP2D6 inhibitor, and was not deemed clinically significant. Therefore, the pharmacokinetics of the individual components is expected to reasonably characterize the overall pharmacokinetics of the combination.

Absorption and Bioavailability

Olanzapine and fluoxetine capsules — Following a single oral 12 mg/50 mg dose of olanzapine and fluoxetine capsules, peak plasma concentrations of olanzapine and fluoxetine occur at approximately 4 and 6 hours, respectively. The effect of food on the absorption and bioavailability of olanzapine and fluoxetine capsules has not been evaluated. The bioavailability of olanzapine given as Zyprexa ^®, and the bioavailability of fluoxetine given as Prozac ^® were not affected by food. It is unlikely that there would be a significant food effect on the bioavailability of olanzapine and fluoxetine capsules.

Olanzapine — Olanzapine is well absorbed and reaches peak concentration approximately 6 hours following an oral dose. Food does not affect the rate or extent of olanzapine absorption when olanzapine is given as Zyprexa ^®. It is eliminated extensively by first pass metabolism, with approximately 40% of the dose metabolized before reaching the systemic circulation.

Fluoxetine — Following a single oral 40 mg dose, peak plasma concentrations of fluoxetine from 15 to 55 ng/mL are observed after 6 to 8 hours. Food does not appear to affect the systemic bioavailability of fluoxetine given as Prozac ^®, although it may delay its absorption by 1 to 2 hours, which is probably not clinically significant.

Distribution

Olanzapine and fluoxetine capsules — The in vitro binding to human plasma proteins of olanzapine and fluoxetine in combination is similar to the binding of the individual components.

Olanzapine — Olanzapine is extensively distributed throughout the body, with a volume of distribution of approximately 1000 L. It is 93% bound to plasma proteins over the concentration range of 7 to 1100 ng/mL, binding primarily to albumin and α ₁-acid glycoprotein.

Fluoxetine — Over the concentration range from 200 to 1000 ng/mL, approximately 94.5% of fluoxetine is bound in vitro to human serum proteins, including albumin and α ₁-glycoprotein. The interaction between fluoxetine and other highly protein-bound drugs has not been fully evaluated [ see Drug Interactions ( 7.7) ].

Metabolism and Elimination

Olanzapine and fluoxetine capsules — Olanzapine and fluoxetine capsule therapy yielded steady-state concentrations of norfluoxetine similar to those seen with fluoxetine in the therapeutic dose range.

Olanzapine — Olanzapine displays linear pharmacokinetics over the clinical dosing range. Its half-life ranges from 21 to 54 hours (5th to 95th percentile; mean of 30 hr), and apparent plasma clearance ranges from 12 to 47 L/hr (5th to 95th percentile; mean of 25 L/hr). Administration of olanzapine once daily leads to steady-state concentrations in about 1 week that are approximately twice the concentrations after single doses. Plasma concentrations, half-life, and clearance of olanzapine may vary between individuals on the basis of smoking status, gender, and age [ see Dosage and Administration ( 2.3) and Clinical Pharmacology ( 12.4) ].

Following a single oral dose of ¹⁴C-labeled olanzapine, 7% of the dose of olanzapine was recovered in the urine as unchanged drug, indicating that olanzapine is highly metabolized. Approximately 57% and 30% of the dose was recovered in the urine and feces, respectively. In the plasma, olanzapine accounted for only 12% of the AUC for total radioactivity, indicating significant exposure to metabolites. After multiple dosing, the major circulating metabolites were the 10-N-glucuronide, present at steady state at 44% of the concentration of olanzapine, and 4´-N-desmethyl olanzapine, present at steady state at 31% of the concentration of olanzapine. Both metabolites lack pharmacological activity at the concentrations observed.

Direct glucuronidation and CYP450-mediated oxidation are the primary metabolic pathways for olanzapine. In vitro studies suggest that CYP1A2, CYP2D6, and the flavin-containing monooxygenase system are involved in olanzapine oxidation. CYP2D6-mediated oxidation appears to be a minor metabolic pathway in vivo, because the clearance of olanzapine is not reduced in subjects who are deficient in this enzyme.

Fluoxetine — Fluoxetine is a racemic mixture (50/50) of R-fluoxetine and S-fluoxetine enantiomers. In animal models, both enantiomers are specific and potent serotonin uptake inhibitors with essentially equivalent pharmacologic activity. The S-fluoxetine enantiomer is eliminated more slowly and is the predominant enantiomer present in plasma at steady state.

Fluoxetine is extensively metabolized in the liver to its only identified active metabolite, norfluoxetine, via the CYP2D6 pathway. A number of unidentified metabolites exist.

In animal models, S-norfluoxetine is a potent and selective inhibitor of serotonin uptake and has activity essentially equivalent to R- or S-fluoxetine. R-norfluoxetine is significantly less potent than the parent drug in the inhibition of serotonin uptake. The primary route of elimination appears to be hepatic metabolism to inactive metabolites excreted by the kidney.

Clinical Issues Related to Metabolism and Elimination

The complexity of the metabolism of fluoxetine has several consequences that may potentially affect the clinical use of olanzapine and fluoxetine capsules.

Variability in Metabolism — A subset (about 7%) of the population has reduced activity of the drug metabolizing enzyme CYP2D6. Such individuals are referred to as “poor metabolizers” of drugs such as debrisoquin, dextromethorphan, and the tricyclic antidepressants (TCAs). In a study involving labeled and unlabeled enantiomers administered as a racemate, these individuals metabolized S-fluoxetine at a slower rate and thus achieved higher concentrations of S-fluoxetine. Consequently, concentrations of S-norfluoxetine at steady state were lower. The metabolism of R-fluoxetine in these poor metabolizers appears normal. When compared with normal metabolizers, the total sum at steady state of the plasma concentrations of the 4 enantiomers was not significantly greater among poor metabolizers. Thus, the net pharmacodynamic activities were essentially the same. Alternative nonsaturable pathways (non-CYP2D6) also contribute to the metabolism of fluoxetine. This explains how fluoxetine achieves a steady-state concentration rather than increasing without limit.

Because the metabolism of fluoxetine, like that of a number of other compounds including TCAs and other selective serotonin antidepressants, involves the CYP2D6 system, concomitant therapy with drugs also metabolized by this enzyme system (such as the TCAs) may lead to drug interactions [ see Drug Interactions ( 7.7) ].

Accumulation and Slow Elimination — The relatively slow elimination of fluoxetine (elimination half-life of 1 to 3 days after acute administration and 4 to 6 days after chronic administration) and its active metabolite, norfluoxetine (elimination half-life of 4 to 16 days after acute and chronic administration), leads to significant accumulation of these active species in chronic use and delayed attainment of steady state, even when a fixed dose is used. After 30 days of dosing at 40 mg/day, plasma concentrations of fluoxetine in the range of 91 to 302 ng/mL and norfluoxetine in the range of 72 to 258 ng/mL have been observed. Plasma concentrations of fluoxetine were higher than those predicted by single-dose studies, because the metabolism of fluoxetine is not proportional to dose. However, norfluoxetine appears to have linear pharmacokinetics. Its mean terminal half-life after a single dose was 8.6 days and after multiple dosing was 9.3 days. Steady-state levels after prolonged dosing are similar to levels seen at 4 to 5 weeks.

The long elimination half-lives of fluoxetine and norfluoxetine assure that, even when dosing is stopped, active drug substance will persist in the body for weeks (primarily depending on individual patient characteristics, previous dosing regimen, and length of previous therapy at discontinuation). This is of potential consequence when drug discontinuation is required or when drugs are prescribed that might interact with fluoxetine and norfluoxetine following the discontinuation of fluoxetine.

Geriatric — Based on the individual pharmacokinetic profiles of olanzapine and fluoxetine, the pharmacokinetics of olanzapine and fluoxetine capsules may be altered in geriatric patients. Caution should be used in dosing the elderly, especially if there are other factors that might additively influence drug metabolism and/or pharmacodynamic sensitivity.

In a study involving 24 healthy subjects, the mean elimination half-life of olanzapine was about 1.5 times greater in elderly subjects (≥65 years of age) than in non-elderly subjects (<65 years of age).

The disposition of single doses of fluoxetine in healthy elderly subjects (≥65 years of age) did not differ significantly from that in younger normal subjects. However, given the long half-life and nonlinear disposition of the drug, a single-dose study is not adequate to rule out the possibility of altered pharmacokinetics in the elderly, particularly if they have systemic illness or are receiving multiple drugs for concomitant diseases. The effects of age upon the metabolism of fluoxetine have been investigated in 260 elderly but otherwise healthy depressed patients (≥60 years of age) who received 20 mg fluoxetine for 6 weeks. Combined fluoxetine plus norfluoxetine plasma concentrations were 209.3 ± 85.7 ng/mL at the end of 6 weeks. No unusual age-associated pattern of adverse reactions was observed in those elderly patients.

Renal Impairment — The pharmacokinetics of olanzapine and fluoxetine capsules has not been studied in patients with renal impairment. However, olanzapine and fluoxetine individual pharmacokinetics do not differ significantly in patients with renal impairment. Olanzapine and fluoxetine capsule dosing adjustment based upon renal impairment is not routinely required.

Because olanzapine is highly metabolized before excretion and only 7% of the drug is excreted unchanged, renal dysfunction alone is unlikely to have a major impact on the pharmacokinetics of olanzapine. The pharmacokinetic characteristics of olanzapine were similar in patients with severe renal impairment and normal subjects, indicating that dosage adjustment based upon the degree of renal impairment is not required. In addition, olanzapine is not removed by dialysis. The effect of renal impairment on olanzapine metabolite elimination has not been studied.

In depressed patients on dialysis (N=12), fluoxetine administered as 20 mg once daily for 2 months produced steady-state fluoxetine and norfluoxetine plasma concentrations comparable with those seen in patients with normal renal function. While the possibility exists that renally excreted metabolites of fluoxetine may accumulate to higher levels in patients with severe renal dysfunction, use of a lower or less frequent dose is not routinely necessary in renally impaired patients.

Hepatic Impairment — Based on the individual pharmacokinetic profiles of olanzapine and fluoxetine, the pharmacokinetics of olanzapine and fluoxetine capsules may be altered in patients with hepatic impairment. The lowest starting dose should be considered for patients with hepatic impairment [ see Dosage and Administration ( 2.3) and Warnings and Precautions ( 5.20)].

Although the presence of hepatic impairment may be expected to reduce the clearance of olanzapine, a study of the effect of impaired liver function in subjects (N=6) with clinically significant cirrhosis (Child-Pugh Classification A and B) revealed little effect on the pharmacokinetics of olanzapine.

As might be predicted from its primary site of metabolism, liver impairment can affect the elimination of fluoxetine. The elimination half-life of fluoxetine was prolonged in a study of cirrhotic patients, with a mean of 7.6 days compared with the range of 2 to 3 days seen in subjects without liver disease; norfluoxetine elimination was also delayed, with a mean duration of 12 days for cirrhotic patients compared with the range of 7 to 9 days in normal subjects.

Gender — Clearance of olanzapine is approximately 30% lower in women than in men. There were, however, no apparent differences between men and women in effectiveness or adverse effects. Dosage modifications based on gender should not be needed.

Smoking Status — Olanzapine clearance is about 40% higher in smokers than in nonsmokers, although dosage modifications are not routinely required.

Race — No olanzapine and fluoxetine capsule pharmacokinetic study was conducted to investigate the effects of race. In vivo studies have shown that exposures to olanzapine are similar among Japanese, Chinese and Caucasians, especially after normalization for body weight differences. Dosage modifications for race, therefore, are not routinely required.

Combined Effects — The combined effects of age, smoking, and gender could lead to substantial pharmacokinetic differences in populations. The clearance of olanzapine in young smoking males, for example, may be 3 times higher than that in elderly nonsmoking females. Olanzapine and fluoxetine capsule dosing modification may be necessary in patients who exhibit a combination of factors that may result in slower metabolism of the olanzapine component [ see Dosage and Administration ( 2.3) ].

Children and Adolescents (ages 10 to 17 years) — Based on the pediatric olanzapine and fluoxetine capsule study, steady-state olanzapine, fluoxetine, and norfluoxetine plasma concentrations were about 31%, 76%, and 38% higher, respectively, in pediatric patients with lower body weights (less than 50 kg) than in pediatric patients with high body weight (greater than or equal to 50 kg). Exposures in pediatric patients with high body weight were similar to those previously observed in adults. Dose modifications based on body weight are not required.

No carcinogenicity, mutagenicity, or fertility studies were conducted with olanzapine and fluoxetine capsules. The following data are based on findings in studies performed with the individual components, therefore all dose multiples (based on body surface area) reflect the maximum recommended human dose (MRHD) of 20 mg olanzapine, or 80 mg fluoxetine, when each drug is administered separately.

Carcinogenesis

Olanzapine — Oral carcinogenicity studies were conducted in mice and rats. Olanzapine was administered to mice in two 78 week studies at doses of 3, 10, and 30/20 mg/kg/day [equivalent to 0.8 to 5 times the maximum recommended human daily dose (MRHD) on a mg/m ² basis] and 0.25, 2, and 8 mg/kg/day (equivalent to 0.06 to 2 times the MRHD on a mg/m ² basis). Rats were dosed for 2 years at doses of 0.25, 1, 2.5, and 4 mg/kg/day (males) and 0.25, 1, 4, and 8 mg/kg/day (females) (equivalent to 0.1 to 2 and 0.1 to 4 times the MRHD on a mg/m ² basis, respectively). The incidence of liver hemangiomas and hemangiosarcomas was significantly increased in 1 mouse study in females dosed at 8 mg/kg/day (2 times the MRHD on a mg/m ² basis). These tumors were not increased in another mouse study in females dosed at 10 or 30/20 mg/kg/day (2 to 5 times the MRHD on a mg/m ² basis); in this study, there was a high incidence of early mortalities in males of the 30/20 mg/kg/day group. The incidence of mammary gland adenomas and adenocarcinomas was significantly increased in female mice dosed at ≥2 mg/kg/day and in female rats dosed at ≥4 mg/kg/day (0.5 and 2 times the MRHD on a mg/m ² basis, respectively). Antipsychotic drugs have been shown to chronically elevate prolactin levels in rodents. Serum prolactin levels were not measured during the olanzapine carcinogenicity studies; however, measurements during subchronic toxicity studies showed that olanzapine elevated serum prolactin levels up to 4-fold in rats at the same doses used in the carcinogenicity study. An increase in mammary gland neoplasms has been found in rodents after chronic administration of other antipsychotic drugs and is considered to be prolactin-mediated. The relevance for human risk of the finding of prolactin-mediated endocrine tumors in rodents is unknown [ see Warnings and Precautions (5.22)].

Fluoxetine — The dietary administration of fluoxetine to rats and mice for 2 years at doses of up to 10 and 12 mg/kg/day, respectively (approximately 1.2 and 0.7 times, respectively, the MRHD on a mg/m ² basis), produced no evidence of carcinogenicity.

Mutagenesis

Olanzapine — No evidence of genotoxic potential for olanzapine was found in the Ames reverse mutation test, in vivo micronucleus test in mice, the chromosomal aberration test in Chinese hamster ovary cells, unscheduled DNA synthesis test in rat hepatocytes, induction of forward mutation test in mouse lymphoma cells, or in vivo sister chromatid exchange test in bone marrow of Chinese hamsters.

Fluoxetine — Fluoxetine and norfluoxetine have been shown to have no genotoxic effects based on the following assays: bacterial mutation assay, DNA repair assay in cultured rat hepatocytes, mouse lymphoma assay, and in vivo sister chromatid exchange assay in Chinese hamster bone marrow cells.

Impairment of Fertility

Olanzapine and fluoxetine capsules — Fertility studies were not conducted with olanzapine and fluoxetine capsules. However, in a repeat-dose rat toxicology study of 3 months duration, ovary weight was decreased in females treated with the low-dose [2 and 4 mg/kg/day (1 and 0.5 times the MRHD on a mg/m ² basis), respectively] and high-dose [4 and 8 mg/kg/day (2 and 1 times the MRHD on a mg/m ² basis), respectively] combinations of olanzapine and fluoxetine. Decreased ovary weight, and corpora luteal depletion and uterine atrophy were observed to a greater extent in the females receiving the high-dose combination than in females receiving either olanzapine or fluoxetine alone. In a 3 month repeat-dose dog toxicology study, reduced epididymal sperm and reduced testicular and prostate weights were observed with the high-dose combination of olanzapine and fluoxetine [5 and 5 mg/kg/day (9 and 2 times the MRHD on a mg/m ² basis), respectively] and with olanzapine alone (5 mg/kg/day or 9 times the MRHD on a mg/m ² basis).

Olanzapine — In an oral fertility and reproductive performance study in rats, male mating performance, but not fertility, was impaired at a dose of 22.4 mg/kg/day and female fertility was decreased at a dose of 3 mg/kg/day (11 and 1.5 times the MRHD on a mg/m ² basis, respectively). Discontinuance of olanzapine treatment reversed the effects on male-mating performance. In female rats, the precoital period was increased and the mating index reduced at 5 mg/kg/day (2.5 times the MRHD on a mg/m ² basis). Diestrous was prolonged and estrous was delayed at 1.1 mg/kg/day (0.6 times the MRHD on a mg/m ² basis); therefore, olanzapine may produce a delay in ovulation.

Fluoxetine — Two fertility studies conducted in adult rats at doses of up to 7.5 and 12.5 mg/kg/day (approximately 0.9 and 1.5 times the MRHD on a mg/m ² basis) indicated that fluoxetine had no adverse effects on fertility. However, adverse effects on fertility were seen when juvenile rats were treated with fluoxetine at a high dose (30 mg/kg) associated with significant toxicity [ see Use in Specific Populations ( 8.4) ].

Efficacy for olanzapine and fluoxetine capsules was established for the:

• Acute treatment of depressive episodes in Bipolar I Disorder in adults, and children and adolescents (10 to 17 years) in 3 short-term, placebo-controlled trials (Studies 1, 2, 3) [ see Clinical Studies ( 14.1) ].
• Acute and maintenance treatment of treatment resistant depression in adults (18 to 85 years) in 3 short-term, placebo-controlled trials (Studies 4, 5, 6) and 1 randomized withdrawal study with an active control (Study 7) [ see Clinical Studies ( 14.2) ].

Adults — The efficacy of olanzapine and fluoxetine capsules for the acute treatment of depressive episodes associated with Bipolar I Disorder was established in 2 identically designed, 8 week, randomized, double-blind, controlled studies of patients who met Diagnostic and Statistical Manual 4th edition (DSM-IV) criteria for Bipolar I Disorder, Depressed utilizing flexible dosing of olanzapine and fluoxetine capsules (6/25, 6/50, or 12/50 mg/day), olanzapine (5 to 20 mg/day), and placebo. These studies included patients (≥18 years of age [n=788]) with or without psychotic symptoms and with or without a rapid cycling course.

The primary rating instrument used to assess depressive symptoms in these studies was the Montgomery-Asberg Depression Rating Scale (MADRS), a 10 item clinician-rated scale with total scores ranging from 0 to 60. The primary outcome measure of these studies was the change from baseline to endpoint in the MADRS total score. In both studies, olanzapine and fluoxetine capsules were statistically significantly superior to both olanzapine monotherapy and placebo in reduction of the MADRS total score. Refer to Table 18 (Studies 1 and 2).

Children and Adolescents — The efficacy of olanzapine and fluoxetine capsules for the acute treatment of depressive episodes associated with Bipolar I Disorder was established in a single 8 week, randomized, double-blind, placebo-controlled study of patients, 10 to 17 years of age [N=255], who met Diagnostic and Statistical Manual 4th edition-Text Revision (DSM-IV-TR) criteria for Bipolar I Disorder, Depressed. Patients were initiated at a dose of 3/25 mg/day and force-titrated to the maximum dose of 12/50 mg/day over two weeks. After Week 2, there was flexible dosing of olanzapine and fluoxetine capsules in the range of 6/25, 6/50, 12/25, or 12/50 mg/day. The average daily dose was olanzapine 7.7 mg and fluoxetine 37.6 mg. The recommended starting dose for children and adolescents is 3/25 mg per day. Flexible dosing is recommended, rather than the forced titration used in the study [ see Dosage and Administration ( 2.1) ]. This study included patients with or without psychotic symptoms.

The primary rating instrument used to assess depressive symptoms in these studies was the Children’s Depressive Rating Scale-Revised (CDRS-R), a 17-item clinician-rated scale with total scores ranging from 17 to 113. The primary outcome measure of this study was the change from baseline to Week 8 in the CDRS-R total score. In this study, olanzapine and fluoxetine capsules were statistically significantly superior to placebo in reduction of the CDRS-R total score. Refer to Table 18 (Study 3).

The efficacy of olanzapine and fluoxetine capsules in acute treatment resistant depression was demonstrated with data from 3 clinical studies (n=579) in adults (18 to 85 years). Doses evaluated in these studies ranged from 6 to 18 mg for olanzapine and 25 to 50 mg for fluoxetine.

An 8 week randomized, double-blind controlled study was conducted to evaluate the efficacy of olanzapine and fluoxetine capsules in patients (n=300) who met DSM-IV criteria for Major Depressive Disorder and did not respond to 2 different antidepressants after at least 6 weeks at or above the minimally effective labeled dosage in their current episode. Patients who were not responding to an antidepressant in their current episode entered an 8-week open-label fluoxetine lead-in; non-responders were randomized (1:1:1) to receive olanzapine and fluoxetine capsules, olanzapine, or fluoxetine, and were treated for 8 weeks. Olanzapine and fluoxetine capsules were flexibly dosed between 6/50 mg, 12/50 mg, and 18/50 mg. Results from this study yielded statistically significant greater reduction in mean total MADRS scores from baseline to endpoint for olanzapine and fluoxetine capsules versus fluoxetine and olanzapine. See Table 19 (Study 4). A second study with the same treatment-resistant patient population (n=28), when analyzed with change in MADRS as the outcome measure, demonstrated statistically significantly greater reduction in MADRS scores for olanzapine and fluoxetine capsules versus fluoxetine and olanzapine. See Table 19 (Study 5). A third study demonstrated statistically significantly greater reduction in total MADRS scores for olanzapine and fluoxetine capsules versus fluoxetine or olanzapine alone, when analyzed in a subpopulation of depressed patients (n=251) who met the definition of treatment resistance (patients who had not responded to 2 antidepressants of adequate dose and duration in the current episode). See Table 19 (Study 6).

^a SD – standard deviation; SE – standard error; LS mean – least-squares mean estimate; CI – unadjusted confidence interval; NA – not available.

^b Difference (olanzapine and fluoxetine capsules minus active comparator or placebo) in least squares estimates.

The efficacy of olanzapine and fluoxetine capsules in the maintenance therapy of treatment-resistant depression was demonstrated in a 47 week study (Study 7) in adults (18 to 65 years). Olanzapine and fluoxetine capsules was dosed between 6/25 mg, 12/25 mg, 6/50 mg, 12/50 mg, and 18/50 mg.

Patients (N=892) met DSM-IV criteria for Major Depressive Disorder and for treatment-resistant depression (a lack of response to 2 antidepressants after at least 6 weeks at or above the minimally effective labeled dose in their current episode of major depressive disorder). Patients were initially treated with open-label olanzapine and fluoxetine capsules; those who responded to and were stabilized on treatment over approximately 20 weeks were randomized to continue receiving treatment with olanzapine and fluoxetine capsules (n=221) or to receive treatment with fluoxetine (n=223) for another 27 weeks. Relapse was assessed using 3 criteria: a 50% increase in Montgomery-Åsberg Depression Rating Scale score from randomization with concomitant Clinical Global Impressions–Severity of Depression score increase to 4 or more; hospitalization due to depression or suicidality; or discontinuation due to lack of efficacy/worsening of depression/suicidality. A total of 15.8% of patients on olanzapine and fluoxetine capsules and 31.8% of patients on fluoxetine relapsed; this difference was statistically significant. Patients receiving continued olanzapine and fluoxetine capsules experienced statistically significantly longer time to relapse over the 27 weeks compared with those receiving fluoxetine ( Figure 1).

Patients should be advised of the following issues and asked to alert their prescriber if these occur while taking olanzapine and fluoxetine capsules.

Prescribers or other health professionals should inform patients, their families, and their caregivers about the potential benefits and potential risks associated with treatment with olanzapine and fluoxetine capsules and should counsel them in their appropriate use. A patient Medication Guide is available for olanzapine and fluoxetine capsules. The prescribers or other health professionals should instruct patients, their families, and their caregivers to read the Medication Guide and should assist them in understanding its contents. Patients should be given the opportunity to discuss the contents of the Medication Guide and to obtain answers to any questions they may have.

Patients, their families, and their caregivers should be encouraged to be alert to the emergence of anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia (psychomotor restlessness), hypomania, mania, other unusual changes in behavior, worsening of depression, and suicidal ideation, especially early during antidepressant treatment and when the dose is adjusted up or down. Families and caregivers of patients should be advised to look for the emergence of such symptoms on a day-to-day basis, since changes may be abrupt. Such symptoms should be reported to the patient's prescriber or health professional, especially if they are severe, abrupt in onset, or were not part of the patient's presenting symptoms. Symptoms such as these may be associated with an increased risk for suicidal thinking and behavior and indicate a need for very close monitoring and possibly changes in the medication [ see Boxed Warning and Warnings and Precautions ( 5.1) ].

Patients and caregivers should be advised that elderly patients with dementia-related psychosis treated with antipsychotic drugs are at increased risk of death. Patients and caregivers should be advised that elderly patients with dementia-related psychosis treated with olanzapine had a significantly higher incidence of cerebrovascular adverse events (e.g., stroke, transient ischemic attack) compared with placebo. Olanzapine and fluoxetine capsules are not approved for elderly patients with dementia-related psychosis [ see Boxed Warning and Warnings and Precautions ( 5.2) ].

Patients and caregivers should be counseled that a potentially fatal symptom complex sometimes referred to as NMS has been reported in association with administration of antipsychotic drugs, including olanzapine, a component of olanzapine and fluoxetine capsules. Signs and symptoms of NMS include hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmia) [ see Warnings and Precautions ( 5.3) ].

Patients should be advised to report to their health care provider at the earliest onset of any signs and symptoms that may be associated with Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) [ see Warnings and Precautions ( 5.4) ].

Patients should be advised of the potential risk of hyperglycemia-related adverse reactions. Patients should be monitored regularly for worsening of glucose control. Patients and caregivers should be counseled that metabolic changes have occurred during treatment with olanzapine and fluoxetine capsules. Patients who have diabetes should follow their doctor's instructions about how often to check their blood sugar while taking olanzapine and fluoxetine capsules [ see Warnings and Precautions ( 5.5) ].

Patients should be counseled that dyslipidemia has occurred during treatment with olanzapine and fluoxetine capsules. Patients should have their lipid profile monitored regularly [ see Warnings and Precautions ( 5.5) ].

Patients should be counseled that weight gain has occurred during treatment with olanzapine and fluoxetine capsules. Patients should have their weight monitored regularly [ see Warnings and Precautions ( 5.5) ].

Patients should be cautioned about the risk of serotonin syndrome with the concomitant use of olanzapine and fluoxetine capsules and other serotonergic agents including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, and St. John’s Wort [ see Contraindications ( 4.1) and Warnings and Precautions ( 5.6), and Drug Interactions ( 7.3) ]. Patients should be advised of the signs and symptoms associated with serotonin syndrome that may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular changes (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). Patients should be cautioned to seek medical care immediately if they experience these symptoms.

Patients should be advised that taking olanzapine and fluoxetine capsules can cause mild pupillary dilation, which in susceptible individuals, can lead to an episode of angle-closure glaucoma. Pre-existing glaucoma is almost always open-angle glaucoma because angle-closure glaucoma, when diagnosed, can be treated definitively with iridectomy. Open-angle glaucoma is not a risk factor for angle-closure glaucoma. Patients may wish to be examined to determine whether they are susceptible to angle-closure, and have a prophylactic procedure (e.g., iridectomy), if they are susceptible [ see Warnings and Precautions ( 5.7) ].

Patients should be advised to notify their physician if they develop a rash or hives [ see Warnings and Precautions ( 5.8) ]. Patients should also be advised of the signs and symptoms associated with a severe allergic reaction, including swelling of the face, eyes, or mouth, or have trouble breathing. Patients should be cautioned to seek medical care immediately if they experience these symptoms.

Patients should be advised of the risk of orthostatic hypotension, especially during the period of initial dose titration and in association with the use of concomitant drugs that may potentiate the orthostatic effect of olanzapine, e.g., diazepam or alcohol [ see Warnings and Precautions (5.11) and Drug Interactions ( 7.6, 7.7) ]. Patients should be advised to change positions carefully to help prevent orthostatic hypotension, and to lie down if they feel dizzy or faint, until they feel better. Patients should be advised to call their doctor if they experience any of the following signs and symptoms associated with orthostatic hypotension: dizziness, fast or slow heart beat, or fainting.

Patients should be cautioned about the concomitant use of olanzapine and fluoxetine capsules and NSAIDs, aspirin, warfarin, or other drugs that affect coagulation since the combined use of psychotropic drugs that interfere with serotonin reuptake and these agents have been associated with an increased risk of bleeding [ see Warnings and Precautions (5.16)]. Patients should be advised to call their doctor if they experience any increased or unusual bruising or bleeding while taking olanzapine and fluoxetine capsules.

Patients should be advised that hyponatremia has been reported during treatment with SNRIs and SSRIs, including olanzapine and fluoxetine capsules. Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which may lead to falls. More severe and/or acute cases have been associated with hallucination, syncope, seizure, coma, respiratory arrest, and death [ see Warnings and Precautions (5.17)].

Olanzapine and fluoxetine capsules have the potential to impair judgment, thinking, or motor skills. Patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that olanzapine and fluoxetine capsule therapy does not affect them adversely [ see Warnings and Precautions (5.18)].

Patients should be advised regarding appropriate care in avoiding overheating and dehydration. Patients should be advised to call their doctor right away if they become severely ill and have some or all of these symptoms of dehydration: sweating too much or not at all, dry mouth, feeling very hot, feeling thirsty, not able to produce urine [ see Warnings and Precautions (5.19)].

Patients should be advised to inform their physician if they are taking Prozac ^®, Prozac ^® Weekly ^™, Sarafem ^®, fluoxetine, Zyprexa ^®, Zyprexa ^® Zydis ^® or Zyprexa ^® Relprevv. Patients should be advised to inform their physicians if they are taking, plan to take, or have stopped taking any prescription or over-the-counter drugs, including herbal supplements, since there is a potential for interactions. Patients should also be advised to inform their physicians if they plan to discontinue any medications they are taking while taking olanzapine and fluoxetine capsules, as stopping a medication may also impact the overall blood level of olanzapine and fluoxetine capsules [ see Warnings and Precautions (5.23)].

Patients should be advised to take olanzapine and fluoxetine capsules exactly as prescribed, and to continue taking olanzapine and fluoxetine capsules as prescribed even after their mood symptoms improve. Patients should be advised that they should not alter their dosing regimen, or stop taking olanzapine and fluoxetine capsules, without consulting their physician [ see Warnings and Precautions (5.25)].

Patients should be advised to avoid alcohol while taking olanzapine and fluoxetine capsules [ see Drug Interactions ( 7.6, 7.7) ].

Pregnancy — Patients should be advised to notify their physician if they become pregnant or intend to become pregnant during olanzapine and fluoxetine capsule therapy. Olanzapine and fluoxetine capsules should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus [ see Use in Specific Populations ( 8.1) ].

Nursing Mothers — Patients, if taking olanzapine and fluoxetine capsules, should be advised not to breast-feed [ see Use in Specific Populations ( 8.3) ].

Pediatric Use ― Safety and efficacy of olanzapine and fluoxetine capsules in patients 10 to 17 years of age have been established for the acute treatment of Depressive Episodes Associated with Bipolar I Disorder. The types of adverse reactions observed with olanzapine and fluoxetine capsules in children and adolescents were generally similar to those observed in adults. However, the magnitude and frequency of some changes were greater in children and adolescents than adults. These included increases in lipids, hepatic enzymes, and prolactin, as well as increases in the QT interval. Educate patients, families, and caregivers about these risks [ see Warnings and Precautions ( 5.5, 5.18, 5.20), Adverse Reactions ( 6.2), and Use in Specific Populations ( 8.4) ].

The frequency of weight gain ≥7%, and the magnitude and frequency of increases in lipids, hepatic analytes, and prolactin in children and adolescents treated with olanzapine and fluoxetine capsules were similar to those observed in adolescents treated with olanzapine monotherapy [ see Warnings and Precautions ( 5.5, 5.20), Adverse Reactions ( 6.2), and Use in Specific Populations ( 8.4) ].

The safety and effectiveness of olanzapine and fluoxetine capsules for the treatment of bipolar I depression in patients under 10 years of age have not been established. The safety and effectiveness of olanzapine and fluoxetine capsules for treatment resistant depression in patients under 18 years of age have not been established.

Patients should be advised that QT interval prolongation and ventricular arrhythmia including Torsade de Pointes have been reported in patients treated with fluoxetine. Signs and symptoms of ventricular arrhythmia include fast, slow, or irregular heart rate, dyspnea, syncope, or dizziness, which may indicate serious cardiac arrhythmia [see Warnings and Precautions ( 5.20)].

Olanzapine (oh-LAN-zah-peen) and Fluoxetine (floo-OX-eh-teen) Capsules

Read the Medication Guide that comes with olanzapine and fluoxetine capsules before you start taking them and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking to your doctor about your medical condition or treatment. Talk with your doctor or pharmacist if there is something you do not understand or you want to learn more about olanzapine and fluoxetine capsules.

What is the most important information I should know about olanzapine and fluoxetine capsules?

Olanzapine and fluoxetine capsules may cause serious side effects, including:

• Suicidal thoughts or actions.
• Increased risk of death in elderly people who are confused, have memory loss and have lost touch with reality (dementia-related psychosis).
• High blood sugar (hyperglycemia).
• High fat levels in your blood (increased cholesterol and triglycerides), especially in children and adolescents age 10 to 17.
• Weight gain, especially in children and adolescents age 10 to 17.

These serious side effects are described below.

1. Suicidal thoughts or actions.

Antidepressant medicines, depression and other serious mental illnesses, and suicidal thoughts or actions:

Talk to your, or your family member's, healthcare provider about:

• all risks and benefits of treatment with antidepressant medicines.
• all treatment choices for depression or other serious mental illness.
• Antidepressant medicines may increase suicidal thoughts or actions in some children, teenagers, and young adults within the first few months of treatment.
• Depression and other serious mental illnesses are the most important causes of suicidal thoughts and actions. Some people may have a particularly high risk of having suicidal thoughts or actions. These include people who have (or have a family history of) bipolar illness (also called manic-depressive illness) or suicidal thoughts or actions.
• How can I watch for and try to prevent suicidal thoughts and actions in myself or a family member?
  • Pay close attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings. This is very important when an antidepressant medicine is started or when the dose is changed.
  • Call the healthcare provider right away to report new or sudden changes in mood, behavior, thoughts, or feelings.
  • Keep all follow-up visits with the healthcare provider as scheduled. Call the healthcare provider between visits as needed, especially if you have concerns about symptoms.

  Call a healthcare provider right away if you or your family member has any of the following symptoms, especially if they are new, worse, or worry you:

  • thoughts about suicide or dying
  • attempts to commit suicide
  • new or worse depression
  • new or worse anxiety
  • feeling very agitated or restless
  • panic attacks
  • trouble sleeping (insomnia)
  • new or worse irritability
  • acting aggressive, being angry, or violent
  • acting on dangerous impulses
  • an extreme increase in activity and talking (mania)
  • or other unusual changes in behavior or mood.

  What else do I need to know about antidepressant medicines?

  • Never stop an antidepressant medicine without first talking to a healthcare provider. Stopping an antidepressant medicine suddenly can cause other symptoms.
  • Antidepressants are medicines used to treat depression and other illnesses. It is important to discuss all the risks of treating depression and also the risks of not treating it. Patients and their families or other caregivers should discuss all treatment choices with the healthcare provider, not just the use of antidepressants.
  • Antidepressant medicines have other side effects. Talk to the healthcare provider about the side effects of the medicine prescribed for you or your family member.
  • Antidepressant medicines can interact with other medicines. Know all of the medicines that you or your family member takes. Keep a list of all medicines to show the healthcare provider. Do not start new medicines without first checking with your healthcare provider.
  • Not all antidepressant medicines prescribed for children are FDA approved for use in children. Talk to your child's healthcare provider for more information.

  2. Increased risk of death in elderly people who are confused, have memory loss and have lost touch with reality (dementia-related psychosis). Olanzapine and fluoxetine capsules are not approved for treating psychosis in elderly people with dementia.

  3. High blood sugar (hyperglycemia): High blood sugar can happen if you have diabetes already or if you have never had diabetes. High blood sugar could lead to:

  • build up of acid in your blood due to ketones (ketoacidosis)
  • coma
  • death

  Your doctor should do tests to check your blood sugar before you start taking olanzapine and fluoxetine capsules and during treatment. In people who do not have diabetes, sometimes high blood sugar goes away when olanzapine and fluoxetine capsules are stopped. People with diabetes and some people who did not have diabetes before taking olanzapine and fluoxetine capsules need to take medicine for high blood sugar even after they stop taking olanzapine and fluoxetine capsules.

  If you have diabetes, follow your doctor's instructions about how often to check your blood sugar while taking olanzapine and fluoxetine capsules.

  Call your doctor if you have any of these symptoms of high blood sugar (hyperglycemia) while taking olanzapine and fluoxetine capsules:

  • feel very thirsty
  • need to urinate more than usual
  • feel very hungry
  • feel weak or tired
  • feel sick to your stomach
  • feel confused, or your breath smells fruity.

  4. High fat levels in your blood (increased cholesterol and triglycerides). High fat levels may happen in people treated with olanzapine and fluoxetine capsules, especially in children and adolescents (10 to 17 years old). You may not have any symptoms, so your doctor should do blood tests to check your cholesterol and triglyceride levels before you start taking olanzapine and fluoxetine capsules and during treatment.

  5. Increase in weight (weight gain): Weight gain is common in people who take olanzapine and fluoxetine capsules. Children and adolescents (10 to 17 years old) who received olanzapine and fluoxetine capsules, were more likely to gain weight and to gain more weight than adults. Some people may gain a lot of weight while taking olanzapine and fluoxetine capsules, so you and your doctor should check your weight regularly. Talk to your doctor about ways to control weight gain, such as eating a healthy, balanced diet, and exercising.

  What are olanzapine and fluoxetine capsules?

  Olanzapine and fluoxetine capsules are a prescription medicine used for:

  • short-term treatment of episodes of depression that happen with Bipolar I Disorder in people age 10 or older.

  Olanzapine and fluoxetine capsules contain two medicines, olanzapine and fluoxetine hydrochloride.

  It is not known if olanzapine and fluoxetine capsules are safe and effective in children under the age of 10.

  The symptoms of Bipolar I Disorder include alternating periods of depression and high or irritable mood, increased activity and restlessness, racing thoughts, talking fast, impulsive behavior, and a decreased need for sleep. With treatment, some of your symptoms of Bipolar I Disorder may improve.
