Revised: 07/2021

Glycopyrrolate oral solution is indicated to reduce chronic severe drooling in patients aged 3 to 16 years with neurologic conditions associated with problem drooling (e.g., cerebral palsy)

Glycopyrrolate oral solution must be measured and administered with an accurate measuring device [see Patient Counseling Information (17)].

Initiate dosing at 0.02 mg/kg orally three times daily and titrate in increments of 0.02 mg/kg every 5-7 days based on therapeutic response and adverse reactions. The maximum recommended dosage is 0.1 mg/kg three times daily not to exceed 1.5-3 mg per dose based upon weight. For greater detail, see Table 1.

During the four-week titration period, dosing can be increased with the recommended dose titration schedule while ensuring that the anticholinergic adverse events are tolerable. Prior to each increase in dose, review the tolerability of the current dose level with the patient’s caregiver.

Glycopyrrolate oral solution should be dosed at least one hour before or two hours after meals.

The presence of high fat food reduces the oral bioavailability of glycopyrrolate oral solution if taken shortly after a meal [see Clinical Pharmacology (12.3)].

Glycopyrrolate oral solution is available as a 1 mg/5 mL clear, cherry-flavored solution for oral administration in 16 ounce bottles.

Glycopyrrolate oral solution is contraindicated in:

• Patients with medical conditions that preclude anticholinergic therapy (e.g., glaucoma, paralytic ileus, unstable cardiovascular status in acute hemorrhage, severe ulcerative colitis, toxic megacolon complicating ulcerative colitis, myasthenia gravis).
• Patients taking solid oral dosage forms of potassium chloride. The passage of potassium chloride tablets through the gastrointestinal (GI) tract may be arrested or delayed with coadministration of glycopyrrolate oral solution.

5.1 Constipation or Intestinal Pseudo-obstruction

Constipation is a common dose-limiting adverse reaction which sometimes leads to glycopyrrolate discontinuation [see Adverse Reactions (6.1)]. Assess patients for constipation, particularly within 4-5 days of initial dosing or after a dose increase. Intestinal pseudo-obstruction has been reported and may present as abdominal distention, pain, nausea or vomiting.

5.2 Incomplete Mechanical Intestinal Obstruction

Diarrhea may be an early symptom of incomplete mechanical intestinal obstruction, especially in patients with ileostomy or colostomy. If incomplete mechanical intestinal obstruction is suspected, discontinue treatment with glycopyrrolate oral solution and evaluate for intestinal obstruction.

5.3 High Ambient Temperatures

In the presence of high ambient temperature, heat prostration (fever and heat stroke due to decreased sweating) can occur with the use of anticholinergic drugs such as glycopyrrolate oral solution. Advise patients/caregivers to avoid exposure of the patient to hot or very warm environmental temperatures.

5.4 Operating Machinery or an Automobile

Glycopyrrolate oral solution may produce drowsiness or blurred vision. As appropriate for a given age, warn the patient not to engage in activities requiring mental alertness such as operating a motor vehicle or other machinery, or performing hazardous work while taking glycopyrrolate oral solution.

5.5 Anticholinergic Drug Effects

Use glycopyrrolate oral solution with caution in patients with conditions that are exacerbated by anticholinergic drug effects including:

• Autonomic neuropathy
• Renal disease
• Ulcerative colitis – Large doses may suppress intestinal motility to the point of producing a paralytic ileus and for this reason may precipitate or aggravate “toxic megacolon”, a serious complication of the disease.
• Hyperthyroidism
• Coronary heart disease, congestive heart failure, cardiac tachyarrhythmias, tachycardia, and hypertension
• Hiatal hernia associated with reflux esophagitis, since anticholinergic drugs may aggravate this condition

The following serious adverse reactions are described elsewhere in the labeling:

• Constipation or intestinal pseudo-obstruction [see Warnings and Precautions (5.1)]
• Incomplete mechanical intestinal obstruction [see Warnings and Precautions (5.2)]

The most common adverse reactions reported with glycopyrrolate oral solution are dry mouth, vomiting, constipation, flushing, and nasal congestion

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 the rates observed in practice.

The data described below reflect exposure to glycopyrrolate oral solution in 151 subjects, including 20 subjects who participated in an 8-week placebo-controlled study (Study 1) and 137 subjects who participated in a 24-week open-label study (six subjects who received glycopyrrolate oral solution in the placebo-controlled study and 131 new subjects).

Table 2 presents adverse reactions reported by ≥ 15% of glycopyrrolate oral solution -treated subjects from the placebo-controlled clinical trial.

The following adverse reactions occurred at a rate of <2% of patients receiving glycopyrrolate oral solution in the open-label study.

Gastrointestinal: Abdominal distention, abdominal pain, stomach discomfort, chapped lips, flatulence, retching, dry tongue General Disorders: Irritability, pain

Infections: Pneumonia, sinusitis, tracheostomy infection, upper respiratory tract infection, urinary tract infection Investigations: Heart rate increase

Metabolism and Nutrition: Dehydration

Nervous System: Headache, convulsion, dysgeusia, nystagmus

Psychiatric: Agitation, restlessness, abnormal behavior, aggression, crying, impulse control disorder, moaning, mood altered Respiratory: Increased viscosity of bronchial secretion, nasal congestion, nasal dryness

Skin: Dry skin, pruritus, rash

Vascular: Pallor

The following adverse reactions have been identified during postapproval use of other formulations of glycopyrrolate for other indications. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Additional adverse reactions identified during postapproval use of glycopyrrolate tablets include: loss of taste and suppression of lactation.

Drugs Affected by Reduced GI Transit Time

Glycopyrrolate reduces GI transit time, which may result in altered release of certain drugs when formulated in delayed- or controlled-release dosage forms.

• The passage of potassium chloride tablets through the GI tract may be arrested or delayed with coadministration of glycopyrrolate. Solid dosage forms of potassium chloride are contraindicated [see Contraindications (4)].
• Digoxin administered as slow dissolution oral tablets may have increased serum levels and enhanced action when administered with glycopyrrolate. Monitor patients receiving slow dissolution digoxin for increased action if glycopyrrolate oral solution is coadministered regularly. Consider the use of other oral dosage forms of digoxin (e.g., elixir or capsules).

Amantadine

The anticholinergic effects of glycopyrrolate may be increased with concomitant administration of amantadine. Consider decreasing the dose of glycopyrrolate during coadministration of amantadine.

Drugs Whose Plasma Levels May be Increased by Glycopyrrolate

Coadministration of glycopyrrolate may result in increased levels of certain drugs.

• Atenolol’s bioavailability may be increased with coadministration of glycopyrrolate. A reduction in the atenolol dose may be needed.
• Metformin plasma levels may be elevated with coadministration of glycopyrrolate, increasing metformin’s pharmacologic and toxic effects. Monitor clinical response to metformin with concomitant glycopyrrolate administration; consider a dose reduction of metformin if warranted.

Drugs Whose Plasma Levels May be Decreased by Glycopyrrolate

Coadministration of glycopyrrolate may result in decreased levels of certain drugs.

• Haloperidol’s serum level may be decreased when coadministered with glycopyrrolate, resulting in worsening of schizophrenic symptoms, and development of tardive dyskinesia. Closely monitor patients if coadministration cannot be avoided.
• Levodopa’s therapeutic effect may be reduced with glycopyrrolate administration. Consider increasing the dose of levodopa.

Risk Summary

There are no available data in pregnant women for glycopyrrolate oral solution to inform decisions concerning any drug-associated risks. In pregnant rats, daily oral administration of glycopyrrolate during organogenesis at dose exposures 2.5 to 113 times the exposure at the maximum recommended human dose (MRHD) did not result in an increased incidence of gross external or visceral defects [ see Data]. When glycopyrrolate was administered intravenously to pregnant rabbits during organogenesis at dose exposures equivalent to up to approximately 7.8 times the exposure at the MRHD, no adverse effects on embryo-fetal development were seen. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

Animal Data

Glycopyrrolate was orally administered to pregnant rats at dosages of 50, 200, and 400 mg/kg/day during the period of organogenesis. These dosages resulted in systemic exposures (estimated AUC _0-inf values) approximately 2.5, 23, and 113 times, respectively, the estimated systemic exposure in humans at the MRHD (9 mg per day, administered in three divided doses). Glycopyrrolate had no effect on maternal survival, but significantly reduced mean maternal body weight gain over the period of dosing at all dosages evaluated. Mean fetal weight was significantly reduced in the 200 and 400 mg/kg/day dose groups. There were two litters with all resorbed fetuses in the 400 mg/kg/day dose group. There were no effects of treatment on the incidence of gross external or visceral defects. Minor treatment-related skeletal effects included reduced ossification of various bones in the 200 and 400 mg/kg/day dose groups; these skeletal effects were likely secondary to maternal toxicity.

Glycopyrrolate was intravenously administered to pregnant rabbits at dosages of 0.1, 0.5, and 1.0 mg/kg/day during the period of organogenesis. These dosages resulted in systemic exposures (estimated AUC _0-inf values) approximately 0.8, 4.6, and 7.8 times, respectively, the estimated systemic exposure in humans at the MRHD. Glycopyrrolate did not affect maternal survival under the conditions of this study. Mean maternal body weight gain and mean food consumption over the period of dosing were lower than the corresponding control value in the 0.5 and 1.0 mg/kg/day treatment groups. There were no effects of treatment on fetal parameters, including fetal survival, mean fetal weight, and the incidence of external, visceral, or skeletal defects.

Female rats that were pregnant or nursing were orally dosed with glycopyrrolate daily at dosages of 0, 50, 200, or 400 mg/kg/day, beginning on day 7 of gestation, and continuing until day 20 of lactation. These dosages resulted in systemic exposures (estimated AUC _0-inf values) approximately 2.5, 23, and 113 times, respectively, the estimated systemic exposure in humans at the MRHD (9 mg per day, administered in three divided doses). Mean body weight of pups in all treatment groups was reduced compared to the control group during the period of nursing, but eventually recovered to be comparable to the control group, post-weaning. No other notable delivery or litter parameters were affected by treatment in any group, including no effects on mean duration of gestation or mean numbers of live pups per litter. No treatment-related effects on survival or adverse clinical signs were observed in pups. There were no effects of maternal treatment on behavior, learning, memory, or reproductive function of pups.

Risk Summary

There are no data on the presence of glycopyrrolate or its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for glycopyrrolate oral solution and any potential adverse effects on the breastfed infant from glycopyrrolate oral solution or from the underlying maternal condition.

Glycopyrrolate oral solution was evaluated for chronic severe drooling in patients aged 3-16 years with neurologic conditions associated with problem drooling. Glycopyrrolate oral solution has not been studied in subjects under the age of 3 years.

Clinical studies of glycopyrrolate oral solution did not include subjects aged 65 and over.

Because glycopyrrolate is largely renally eliminated, glycopyrrolate oral solution should be used with caution in patients with renal impairment [see Clinical Pharmacology (12.3)].

Because glycopyrrolate is a quaternary amine which does not easily cross the blood-brain barrier, symptoms of glycopyrrolate over dosage are generally more peripheral in nature rather than central compared to other anticholinergic agents. In case of accidental overdose, therapy may include:

• Maintain an open airway, providing ventilation as necessary.
• Managing any acute conditions such as hyperthermia, coma and or seizures as applicable, and managing any jerky myoclonic movements or choreoathetosis which may lead to rhabdomyolysis in some cases of anticholinergic over dosage.
• Administering a quaternary ammonium anticholinesterase such as neostigmine to help alleviate-peripheral anticholinergic effects such as anticholinergic induced ileus.
• Administering activated charcoal orally as appropriate.

Glycopyrrolate oral solution is an anticholinergic drug available as an oral solution containing 1 mg glycopyrrolate per 5 mL. The chemical name for glycopyrrolate is pyrrolidinium, 3-[(cyclopentylhydroxyphenylacetyl) oxy]-1,1-dimethyl-bromide. The chemical structure is:

Structure (Structure)

The empirical formula for glycopyrrolate oral solution is C ₁₉H ₂₈BrNO ₃ and the molecular weight is 398.33. The inactive ingredients in glycopyrrolate oral solution are: citric acid, glycerin, sour cherry flavor, ethyl paraben, propylene glycol, propyl paraben, saccharin sodium, sodium citrate, sorbitol solution, and purified water

Glycopyrrolate is a competitive inhibitor of acetylcholine receptors that are located on certain peripheral tissues, including salivary glands. Glycopyrrolate indirectly reduces the rate of salivation by preventing the stimulation of these receptors.

Glycopyrrolate inhibits the action of acetylcholine on salivary glands thereby reducing the extent of salivation.

Absorption

In a parallel study of children (n=6 per group) aged 7-14 years undergoing intraocular surgery, subjects received either intravenous (IV) or oral glycopyrrolate as a premedication. The mean absolute bioavailability of oral glycopyrrolate tablets was low (approximately 3%) and highly variable among subjects (range 1.3 to 13.3%). A similar pattern of low and variable relative bioavailability is seen in adults.

Analysis of population pharmacokinetic data from normal adults and children with cerebral palsy associated chronic moderate to severe drooling failed to demonstrate linear pharmacokinetics across the dose range. In the same analysis, population estimates of the apparent oral clearance (scaled by weight in children and adults) ranged from 5.28 - 38.95 L/hr/kg for healthy adults and 8.07 - 25.65 L/hr/kg for patients with cerebral palsy, a reflection of the low and highly variable oral bioavailability of glycopyrrolate.

Absorption of glycopyrrolate oral solution (fasting) was compared to that of a marketed glycopyrrolate oral tablet. The Cmax after oral solution administration was 23% lower compared to tablet administration and AUC0-inf was 28% lower after oral solution administration. Mean Cmax after oral solution administration in the fasting state was 0.318 ng/mL, and mean AUC _0-24 was 1.74 ng.hr/mL. Mean time to maximum plasma concentration for glycopyrrolate oral solution was 3.1 hours, and mean plasma half-life was 3.0 hours.

In healthy adults, a high fat meal was shown to significantly affect the absorption of glycopyrrolate oral solution (10 mL, 1 mg/5 mL). The mean Cmax under fed high fat meal conditions was approximately 74% lower than the Cmax observed under fasting conditions. Similarly, mean AUC _0-T was reduced by about 78% by the high fat meal compared with the fasting AUC _0-T. A high fat meal markedly reduces the oral bioavailability of glycopyrrolate oral solution. Therefore, glycopyrrolate oral solution should be dosed at least one hour before or two hours after meals. Pharmacokinetic results (mean ± SD) are described in Table 3.

Distribution

After IV administration, glycopyrrolate has a mean volume of distribution in children aged 1 to 14 years of approximately 1.3 to 1.8 L/kg, with a range from 0.7 to 3.9 L/kg. In adults aged 60-75 years, the volume of distribution was lower (0.42 L/kg +/- 0.22).

Metabolism

In adult patients who underwent surgery for cholelithiasis and were given a single IV dose of tritiated glycopyrrolate, approximately 85% of total radioactivity was excreted in urine and <5% was present in T-tube drainage of bile. In both urine and bile, >80% of the radioactivity corresponded to unchanged drug. These data suggest a small proportion of IV glycopyrrolate is excreted as one or more metabolites.

Elimination

Approximately 65-80% of an IV glycopyrrolate dose was eliminated unchanged in urine in adults. In two studies, after IV administration to pediatric patients ages 1-14 years, mean clearance values ranged from 1.01- 1.41 L/kg/hr (range 0.32 -2.22 L/kg/hr). In adults, IV clearance values were 0.54 ± 0.14 L/kg/hr.

Pediatrics

The estimated apparent clearance of glycopyrrolate from a population pharmacokinetic analysis (scaled by weight in children and adults) of oral and IV data was found to be 13.2 L/hr/kg or 92.7 L/hr for a typical 70 kg subject. In the same population based analysis, gender was not identified as having an effect on either glycopyrrolate clearance or systemic exposure.

Gender

Population pharmacokinetic evaluation of adults and children administered IV or oral glycopyrrolate identified no effect of gender on glycopyrrolate clearance or systemic exposure.

Race

The pharmacokinetics of glycopyrrolate by race has not been characterized.

Elderly

Glycopyrrolate pharmacokinetics have not been characterized in the elderly.

Renal Impairment

In one study, glycopyrrolate 4 mcg/kg was administered intravenously in uremic patients undergoing renal transplantation surgery. Mean AUC (10.6 mcg·h/L), mean plasma clearance (0.43 L/hr/kg) and mean 3-hour urinary excretion (0.7%) for glycopyrrolate were significantly different than those of control patients (3.73 µg·h/L, 1.14 L/hr/kg, and 50%, respectively). These results suggest that elimination of glycopyrrolate is severely impaired in patients with renal failure.

Hepatic Impairment

Glycopyrrolate is largely renally eliminated. The pharmacokinetics of glycopyrrolate have not been evaluated in patients with hepatic impairment

When glycopyrrolate was administered via oral gavage to mice for up to 24 months at dosages of 2.5, 7, and 20 mg/kg/day in both genders, resulting in systemic exposures (estimated AUC _0-inf values) approximately 0.1, 0.3, and 0.8 times, respectively, the estimated systemic exposure in humans at the MRHD (9 mg per day, administered in three divided doses), no significant changes in tumor incidence were observed when compared to control.

When glycopyrrolate was administered via oral gavage to rats for up to 24 months at dosages of 5, 15, and 40 mg/kg/day in both genders, resulting in systemic exposures approximately 0.2, 0.8, and 2 times, respectively, the estimated systemic exposure in humans at the MRHD, no significant changes in tumor incidence were observed when compared to control.

Glycopyrrolate did not elicit any genotoxic effects in the Ames mutagenicity assay, the human lymphocyte chromosome aberration assay, or the micronucleus assay.

Glycopyrrolate was assessed for effects on fertility or general reproductive function in rats. Rats of both genders received glycopyrrolate at dosages up to 100 mg/kg/day via oral gavage, resulting in systemic exposures (estimated AUC0-inf values) in males and females up to approximately 11 and 15 times, respectively, the estimated systemic exposure in humans at the MRHD. No treatment-related effects on fertility or reproductive parameters were observed in either gender in this study.

Glycopyrrolate oral solution was evaluated in a multi-center, randomized, double-blind, placebo-controlled, parallel, eight-week study for the control of pathologic drooling in children (Study 1). The study enrolled 38 subjects aged 3-23 years; thirty-six subjects were aged 3-16 years and two patients were greater than 16 years. The subjects were male or female, weighed at least 13 kg (27 lbs), and had cerebral palsy, mental retardation, or another neurologic condition associated with problem drooling defined as drooling in the absence of treatment so that clothing became damp on most days (approximately five to seven days per week). Subjects were randomized in a 1:1 fashion to receive glycopyrrolate oral solution or placebo. Doses of study medication were titrated over a 4-week period to optimal response beginning at 0.02 mg/kg three times a day increasing doses in increments of approximately 0.02 mg/kg three times per day every 5-7 days, not to exceed the lesser of approximately 0.1 mg/kg three times per day or 3 mg three times per day.

Subjects were evaluated on the 9-point modified Teacher’s Drooling Scale (mTDS), which is presented below. The mTDS evaluations were recorded by parents/caregivers 3 times daily approximately two hours post-dose on evaluation days during pre-treatment baseline and at Weeks 2, 4, 6 and 8 of therapy.

Modified Teacher’s Drooling Scale

1= Dry: never drools

2= Mild: only the lips are wet; occasionally

3= Mild: only the lips are wet; frequently

4= Moderate: wet on the lips and chin; occasionally 5= Moderate: wet on the lips and chin; frequently

6= Severe: drools to the extent that clothing becomes damp; occasionally

7= Severe: drools to the extent that clothing becomes damp; frequently

8= Profuse: clothing, hands, tray, and objects become wet; occasionally

9= Profuse: clothing, hands, tray, and objects become wet; frequently

Responders were defined as subjects with at least a 3-point reduction in mean daily m TDS scores from baseline to Week 8. Table 4 presents the proportion of responders at Week 8 and Figure 1 presents the mean m TDS values from baseline through Week 8.

• Advise patients/caregivers to measure glycopyrrolate oral solution with an accurate measuring device. A household teaspoon is not an accurate measuring device. Patients/caregivers should use a dosing cup available in pharmacies to accurately measure the correct milliliter dose. An oral syringe, also available in pharmacies, should be used to dispense glycopyrrolate oral solution into the child’s mouth from the cup. A pharmacist can recommend an appropriate measuring device and can provide instructions for measuring the correct dose.
• Administering glycopyrrolate oral solution with a high fat meal substantially reduces the amount of glycopyrrolate absorbed. Administer glycopyrrolate oral solution at least one hour before or two hours after meals.
• Glycopyrrolate oral solution is started at a low dose and gradually titrated over a period of weeks based on therapeutic response and adverse reactions. Patients/caregivers should not increase the dose without the physician’s permission.
• Common adverse reactions from glycopyrrolate oral solution include overly dry mouth, constipation, vomiting, flushing of the skin or face, and urinary retention. Side effects can sometimes be difficult to detect in some patients with neurologic problems who cannot adequately communicate how they feel. If side effects become troublesome after increasing a dose, decrease the dose to the prior one and contact your physician.
• Constipation is the most common side effect of glycopyrrolate, and if constipation occurs, stop administering glycopyrrolate to the patient and call their healthcare practitioner.
• Inability of the patient to urinate, dry diapers or undergarments, irritability or crying may be signs of urinary retention, and if urinary retention occurs, patients/caregivers should stop administering glycopyrrolate and call their healthcare practitioner.
• If the patient develops a skin rash, hives or an allergic reaction, parents/caregivers should stop administering glycopyrrolate and call their healthcare practitioner as this could be a sign of hypersensitivity to this product.
• Drugs like glycopyrrolate can reduce sweating, and if the patient is in a hot environment and flushing of the skin occurs this may be due to overheating. Avoid exposure of the patient to hot or very warm environmental temperatures to avoid overheating and the possibility of heat exhaustion or heat stroke.

PATIENT and CAREGIVER INFORMATION

Glycopyrrolate oral solution

Please read the Patient and Caregiver Information that comes with glycopyrrolate oral solution before you start giving it to your child, and each time you get a refill. This leaflet does not take the place of talking with your doctor about your child’s medical condition or treatment.

What is glycopyrrolate oral solution?

Glycopyrrolate oral solution is a prescription medicine used in children with medical conditions that cause too much (abnormal) drooling.

Who should not take glycopyrrolate oral solution?

Do not give glycopyrrolate oral solution to anyone who:

• has problems urinating
• has a bowel problem called paralytic ileus
• lacks normal bowel tone or tension
• has severe ulcerative colitis or certain other serious bowel problems with severe ulcerative colitis
• has myasthenia gravis

What should I tell my doctor before giving glycopyrrolate oral solution to my child?

Tell your doctor if your child:

• has any allergies
• has any stomach or bowel problems, including ulcerative colitis
• has any problems with constipation
• has thyroid problems
• has high blood pressure
• has heart problems or abnormal heart beats
• has a hiatal hernia with gastroesophageal reflux disease (GERD)
• has any eye problems
• has any problems urinating
• has any other medical conditions
• is pregnant or plans to become pregnant. It is not known if glycopyrrolate oral solution can harm an unborn baby.
• is breastfeeding or plans to breastfeed. It is not known if glycopyrrolate oral solution passes into breast milk and if it can harm the baby.

Tell your doctor about all of the medicines that your child takes, including prescription and non-prescription medicines, vitamins, and herbal supplements. Some medicine may affect the way glycopyrrolate oral solution works, and glycopyrrolate oral solution may affect how some other medicines work.

How should I give glycopyrrolate oral solution?

• Give glycopyrrolate oral solution exactly as prescribed by your child’s doctor.
• Give glycopyrrolate oral solution 1 hour before or 2 hours after meals.
• Your doctor will tell you how much (milliliters or mLs) of glycopyrrolate oral solution to give your child.
• Do not change the dose of glycopyrrolate oral solution unless your doctor tells you to.
• You must measure the dose of glycopyrrolate oral solution before giving it to your child. Use a special marked dose measuring cup (available at most pharmacies) to measure the right dose of glycopyrrolate oral solution.
• To help make sure that your child swallows the dose, you should use an oral syringe to give the child each dose of glycopyrrolate oral solution, after you measure the dose needed with a dose measuring cup. Oral syringes are also available at most pharmacies.
• If you have questions about how to measure the dose or how to use an oral syringe, ask your pharmacist or doctor.
• The dose of glycopyrrolate oral solution that is needed to control drooling may be different for each child. Glycopyrrolate oral solution is usually started at a low dose, and slowly increased as directed by your doctor. This slow increase in dose continues until the best dose for your child is reached, to control drooling.
• During this time it is important to stay in close contact with your child’s doctor, and tell the doctor about any side effects that your child has. See “What are the possible side effects of glycopyrrolate oral solution?"

What should I avoid while taking glycopyrrolate oral solution?

• Glycopyrrolate oral solution may cause sleepiness or blurred vision. Do not drive a car, operate heavy machinery, or do other dangerous activities while taking glycopyrrolate oral solution.
• Avoid overheating. See “What are the possible side effects of glycopyrrolate oral solution?”

What are the possible side effects of glycopyrrolate oral solution?

Glycopyrrolate oral solution can cause serious side effects including:

• Constipation. Constipation is common with glycopyrrolate oral solution. Tell your doctor if your child strains with bowel movements, goes longer between bowel movements, cannot have a bowel movement, or their stomach is firm and large. The dose of glycopyrrolate oral solution may need to be decreased or stopped.
• Diarrhea and intestinal blockage. Diarrhea can be an early symptom of a blockage in the intestine. This is especially true if your child has a colostomy or ileostomy. Tell your doctor if your child has any diarrhea while taking glycopyrrolate oral solution.
• Problems with control of body temperature (overheating or heat stroke). Glycopyrrolate oral solution can cause your child to sweat less. Your child can become overheated, and develop heat stroke if they are in an area that is very hot. Avoid overheating. Call your doctor right away if your child becomes sick and has any of these symptoms of heatstroke:
• hot, red skin
• decreased alertness or passing out (unconsciousness)
• fast, weak pulse
• fast, shallow breathing
