Warning: Loss Of Bone Mineral Density
Women who use Medroxyprogesterone acetate Contraceptive Injection may lose significant bone mineral density. Bone loss is greater with increasing duration of use and may not be completely reversible.It is unknown if use of Medroxyprogesterone acetate Contraceptive Injection during adolescence or early adulthood, a critical period of bone accretion, will reduce peak bone mass and increase the risk for osteoporotic fracture in later life.Medroxyprogesterone acetate Contraceptive Injection should not be used as a long-term birth control method (i.e., longer than 2 years) unless other birth control methods are considered inadequate. [See Warnings and Precautions (5.1)].
1 Indications And Usage
Medroxyprogesterone acetate is indicated only for the prevention of pregnancy. The loss of bone mineral density (BMD) in women of all ages and the impact on peak bone mass in adolescents should be considered, along with the decrease in BMD that occurs during pregnancy and/or lactation, in the risk/benefit assessment for women who use Medroxyprogesterone acetate long-term [see Warnings and Precautions (5.1)].
2.1 Prevention Of Pregnancy
Both the 1 mL vial and the 1 mL prefilled syringe of Medroxyprogesterone acetate should be vigorously shaken just before use to ensure that the dose being administered represents a uniform suspension.The recommended dose is 150 mg of Medroxyprogesterone acetate every 3 months (13 weeks) administered by deep intramuscular (IM) injection using strict aseptic technique in the gluteal or deltoid muscle, rotating the sites with every injection. As with any IM injection, to avoid an inadvertent subcutaneous injection, body habitus should be assessed prior to each injection to determine if a longer needle is necessary particularly for gluteal IM injection.Medroxyprogesterone acetate should not be used as a long-term birth control method (i.e. longer than 2 years) unless other birth control methods are considered inadequate. Dosage does not need to be adjusted for body weight [See Clinical Studies (14.1)].To ensure the patient is not pregnant at the time of the first injection, the first injection should be given ONLYduring the first 5 days of a normal menstrual period; ONLY within the first 5-days postpartum if not breast-feeding; and if exclusively breast-feeding, ONLY at the sixth postpartum week. If the time interval between injections is greater than 13 weeks, the physician should determine that the patient is not pregnant before administering the drug. The efficacy of Medroxyprogesterone acetate depends on adherence to the dosage schedule of administration.
2.2 Switching From Other Methods Of Contraception
When switching from other contraceptive methods, Medroxyprogesterone acetate should be given in a manner that ensures continuous contraceptive coverage based upon the mechanism of action of both methods, (e.g., patients switching from oral contraceptives should have their first injection of Medroxyprogesterone acetate on the day after the last active tablet or at the latest, on the day following the final inactive tablet).
3 Dosage Forms And Strengths
Sterile Aqueous suspension: 150 mg/mlPrefilled syringes are available packaged with a 22-gauge × 1 1/2 inch Needle Pro® EDGE™ Safety Device.
- The use of Medroxyprogesterone acetate is contraindicated in the following conditions:Known or suspected pregnancy or as a diagnostic test for pregnancy.Active thrombophlebitis, or current or past history of thromboembolic disorders, or cerebral vascular disease [see Warnings and Precautions (5.2)].Known or suspected malignancy of breast [see Warnings and Precautions (5.3)].Known hypersensitivity to Medroxyprogesterone acetate or any of its other ingredients [see Warnings and Precautions (5.5)].Significant liver disease [see Warnings and Precautions (5.6)].Undiagnosed vaginal bleeding [see Warnings and Precautions (5.9)].
5.1 Loss Of Bone Mineral Density
Use of Medroxyprogesterone acetate reduces serum estrogen levels and is associated with significant loss of bone mineral density (BMD). This loss of BMD is of particular concern during adolescence and early adulthood, a critical period of bone accretion. It is unknown if use of Medroxyprogesterone acetate by younger women will reduce peak bone mass and increase the risk for osteoporotic fracture in later life.After discontinuing Medroxyprogesterone acetate in adolescents, mean BMD loss at total hip and femoral neck did not fully recover by 60 months (240 weeks) post-treatment [see Clinical Studies (14.3)]. Similarly, in adults, there was only partial recovery of mean BMD at total hip, femoral neck and lumbar spine towards baseline by 24 months post-treatment. [See Clinical Studies (14.2).]Medroxyprogesterone acetate should not be used as a long-term birth control method (i.e., longer than 2 years) unless other birth control methods are considered inadequate. BMD should be evaluated when a woman needs to continue to use Medroxyprogesterone acetate long-term. In adolescents, interpretation of BMD results should take into account patient age and skeletal maturity.Other birth control methods should be considered in the risk/benefit analysis for the use of Medroxyprogesterone acetate in women with osteoporosis risk factors. Medroxyprogesterone acetate can pose an additional risk in patients with risk factors for osteoporosis (e.g., metabolic bone disease, chronic alcohol and/or tobacco use, anorexia nervosa, strong family history of osteoporosis or chronic use of drugs that can reduce bone mass such as anticonvulsants or corticosteroids). Although there are no studies addressing whether calcium and Vitamin D may lessen BMD loss in women using Medroxyprogesterone acetate, all patients should have adequate calcium and Vitamin D intake.
5.2 Thromboembolic Disorders
There have been reports of serious thrombotic events in women using Medroxyprogesterone acetate (150 mg). However, Medroxyprogesterone acetate has not been causally associated with the induction of thrombotic or thromboembolic disorders. Any patient who develops thrombosis while undergoing therapy with Medroxyprogesterone acetate should discontinue treatment unless she has no other acceptable options for birth control.Do not readminister Medroxyprogesterone acetate pending examination if there is a sudden partial or complete loss of vision or if there is a sudden onset of proptosis, diplopia, or migraine. Do not readminister if examination reveals papilledema or retinal vascular lesions.
Breast CancerWomen who have or have had a history of breast cancer should not use hormonal contraceptives, including Medroxyprogesterone acetate, because breast cancer may be hormonally sensitive [see Contraindications (4)]. Women with a strong family history of breast cancer should be monitored with particular care.The results of five large case-control studies1, 2, 3, 4, 5 assessing the association between depomedroxyprogesteroneacetate (DMPA) use and the risk of breast cancer are summarized in Figure 1. Three of the studies suggest a slightly increased risk of breast cancer in the overall population of users; these increased risks were statistically significant in one study. One recent US study1 evaluated the recency and duration of use and found a statistically significantly increased risk of breast cancer in recent users (defined as last use within the past five years) who used DMPA for 12 months or longer; this is consistent with results of a previous study4.Odds ratio estimates were adjusted for the following covariates:Lee et al. (1987): age, parity, and socioeconomic status.Paul et al. (1989): age, parity, ethnic group, and year of interview.WHO (1991): age, center, and age at first live birth.Shapiro et al. (2000): age, ethnic group, socioeconomic status, and any combined estrogen/progestogen oral contraceptive use.Li et al. (2012): age, year, BMI, duration of OC use, number of full-term pregnancies, family history of breast cancer, and history of screening mammography.Based on the published SEER-18 2011 incidence rate (age-adjusted to the 2000 US Standard Population) of breast cancer for US women, all races, age 20 to 49 years6, a doubling of risk would increase the incidence of breast cancer in women who use Medroxyprogesterone acetate from about 72 to about 144 cases per 100,000 women.
Cervical CancerA statistically nonsignificant increase in RR estimates of invasive squamous-cell cervical cancer has been associated with the use of Medroxyprogesterone acetate in women who were first exposed before the age of 35 years (RR 1.22 to 1.28 and 95% CI 0.93 to 1.70). The overall, nonsignificant relative rate of invasive squamous-cell cervical cancer in women who ever used Medroxyprogesterone acetate was estimated to be 1.11 (95% CI 0.96 to 1.29). No trends in risk with duration of use or times since initial or most recent exposure were observed.
Other CancersLong-term case-controlled surveillance of users of Medroxyprogesterone acetate found no overall increased risk of ovarian or liver cancer.
HIV protease inhibitors and non-nucleoside reverse transcriptase inhibitors: Significant changes (increase or decrease) in the plasma levels of progestin have been noted in some cases of co-administration of HIV protease inhibitors. Significant changes (increase or decrease) in the plasma levels of the progestin have been noted in some cases of co-administration with non-nucleoside reverse transcriptase inhibitors.
Antibiotics: There have been reports of pregnancy while taking hormonal contraceptives and antibiotics, but clinical pharmacokinetic studies have not shown consistent effects of antibiotics on plasma concentrations of synthetic steroids.Consult the labeling of all concurrently-used drugs to obtain further information about interactions with hormonal contraceptives or the potential for enzyme alterations.
AbsorptionFollowing a single 150 mg IM dose of Medroxyprogesterone acetate in eight women between the ages of 28 and 36 years old, medroxyprogesterone acetate concentrations, measured by an extracted radioimmunoassay procedure, increase for approximately 3 weeks to reach peak plasma concentrations of 1 to 7 ng/mL.
DistributionPlasma protein binding of MPA averages 86%. MPA binding occurs primarily to serum albumin. No binding of MPA occurs with sex-hormone-binding globulin (SHBG).
MetabolismMPA is extensively metabolized in the liver by P450 enzymes. Its metabolism primarily involves ring A and/or side-chain reduction, loss of the acetyl group, hydroxylation in the 2-, 6-, and 21-positions or a combination of these positions, resulting in more than 10 metabolites.
ExcretionThe concentrations of medroxyprogesterone acetate decrease exponentially until they become undetectable (<100 pg/mL) between 120 to 200 days following injection. Using an unextracted radioimmunoassay procedure for the assay of medroxyprogesterone acetate in serum, the apparent half-life for medroxyprogesterone acetate following IM administration of Medroxyprogesterone acetate is approximately 50 days. Most medroxyprogesterone acetate metabolites are excreted in the urine as glucuronide conjugates with only minor amounts excreted as sulfates.
Specific PopulationsThe effect of hepatic and/or renal impairment on the pharmacokinetics of Medroxyprogesterone acetate is unknown.
BMD recovery post-treatment in adolescent womenLonger duration of treatment and smoking were associated with less recovery of BMD following the last injection of Medroxyprogesterone acetate. Table 6 shows the extent of recovery of BMD up to 60 months post-treatment for adolescent women who received Medroxyprogesterone acetate for two years or less compared to more than two years. Post-treatment follow-up showed that, in women treated for more than two years, only lumbar spine BMD recovered to baseline levels after treatment was discontinued. Subjects treated with Medroxyprogesterone acetate for more than two years did not recover to their baseline BMD level at femoral neck and total hip even up to 60 months post-treatment. Adolescent women in the untreated cohort gained BMD throughout the trial period (data not shown).Table 6: Extent of BMD Recovery (Months Post-Treatment) in Adolescents by Years of Medroxyprogesterone acetate Use (2 Years or Less vs. More than 2 Years)Duration of Treatment2 years or lessMore than 2 yearsNMean % Change from baselineNMean % Change from baselineTotal Hip BMDEnd of Treatment49-1.5%49-6.2% 12 M post-treatment33-1.4%24-4.6% 24 M post-treatment180.3%17-3.6% 36 M post-treatment122.1%11-4.6% 48 M post-treatment101.3%9-2.5% 60 M post-treatment30.2%2-1.0%Femoral Neck BMDEnd of Treatment49-1.6%49-5.8% 12 M post-treatment33-1.4%24-4.3% 24 M post-treatment180.5%17-3.8% 36 M post-treatment121.2%11-3.8% 48 M post-treatment102.0%9-1.7% 60 M post-treatment31.0%2-1.9%Lumbar Spine BMDEnd of Treatment49-0.9%49-3.5% 12 M post-treatment330.4%23-1.1% 24 M post-treatment182.6%171.9% 36 M post-treatment122.4%110.6% 48 M post-treatment106.5%93.5% 60 M post-treatment36.2%25.7%

5.4 Ectopic Pregnancy
Be alert to the possibility of an ectopic pregnancy among women using Medroxyprogesterone acetate who become pregnant or complain of severe abdominal pain.
5.5 Anaphylaxis And Anaphylactoid Reaction
Anaphylaxis and anaphylactoid reaction have been reported with the use of Medroxyprogesterone acetate. Institute emergency medical treatment if an anaphylactic reaction occurs.
5.6 Injection Site Reactions
Injection site reactions have been reported with use of Medroxyprogesterone acetate [see Adverse Reactions (6.2)]. Persistent injection site reactions may occur after administration of Medroxyprogesterone acetate due to inadvertent subcutaneous administration or release of the drug into the subcutaneous space while removing the needle [see Dosage and Administration (2.1)].
5.7 Liver Function
Discontinue Medroxyprogesterone acetate use if jaundice or acute or chronic disturbances of liver function develop. Do not resume use until markers of liver function return to normal and Medroxyprogesterone acetate causation has been excluded.
There have been a few reported cases of convulsions in patients who were treated with Medroxyprogesterone acetate. Association with drug use or pre-existing conditions is not clear.
Monitor patients who have a history of depression and do not readminister Medroxyprogesterone acetate if depression recurs.
5.10 Bleeding Irregularities
Most women using Medroxyprogesterone acetate experience disruption of menstrual bleeding patterns. Altered menstrual bleeding patterns include amenorrhea, irregular or unpredictable bleeding or spotting, prolonged spotting or bleeding, and heavy bleeding. Rule out the possibility of organic pathology if abnormal bleeding persists or is severe, and institute appropriate treatment.As women continue using Medroxyprogesterone acetate, fewer experience irregular bleeding and more experience amenorrhea. In clinical studies of Medroxyprogesterone acetate, by month 12 amenorrhea was reported by 55% of women, and by month 24, amenorrhea was reported by 68% of women using Medroxyprogesterone acetate.
5.11 Weight Gain
Women tend to gain weight while on therapy with Medroxyprogesterone acetate. From an initial average body weight of 136 lb, women who completed 1 year of therapy with Medroxyprogesterone acetate gained an average of 5.4 lb. Women who completed 2 years of therapy gained an average of 8.1 lb. Women who completed 4 years gained an average of 13.8 lb. Women who completed 6 years gained an average of 16.5 lb. Two percent of women withdrew from a large-scale clinical trial because of excessive weight gain.
5.12 Carbohydrate Metabolism
A decrease in glucose tolerance has been observed in some patients on Medroxyprogesterone acetate treatment. Monitor diabetic patients carefully while receiving Medroxyprogesterone acetate.
Detectable amounts of drug have been identified in the milk of mothers receiving Medroxyprogesterone acetate. In nursing mothers treated with Medroxyprogesterone acetate, milk composition, quality, and amount are not adversely affected. Neonates and infants exposed to medroxyprogesterone from breast milk have been studied for developmental and behavioral effects through puberty. No adverse effects have been noted.
5.14 Fluid Retention
Because progestational drugs including Medroxyprogesterone acetate may cause some degree of fluid retention, monitor patients with conditions that might be influenced by this condition, such as epilepsy, migraine, asthma, and cardiac or renal dysfunction.
5.15 Return Of Fertility
Return to ovulation and fertility is likely to be delayed after stopping Medroxyprogesterone acetate. In a large US study of women who discontinued use of Medroxyprogesterone acetate to become pregnant, data are available for 61% of them. Of the 188 women who discontinued the study to become pregnant, 114 became pregnant. Based on Life-Table analysis of these data, it is expected that 68% of women who do become pregnant may conceive within 12 months, 83% may conceive within 15 months, and 93% may conceive within 18 months from the last injection. The median time to conception for those who do conceive is 10 months following the last injection with a range of 4 to 31 months, and is unrelated to the duration of use. No data are available for 39% of the patients who discontinued Medroxyprogesterone acetate to become pregnant and who were lost to follow-up or changed their mind.
5.16 Sexually Transmitted Diseases
Patients should be counseled that Medroxyprogesterone acetate does not protect against HIV infection (AIDS) and other sexually transmitted diseases.
Although Medroxyprogesterone acetate should not be used during pregnancy, there appears to be little or no increased risk of birth defects in women who have inadvertently been exposed to medroxyprogesterone acetate injections in early pregnancy. Neonates exposed to medroxyprogesterone acetate in-utero and followed to adolescence showed no evidence of any adverse effects on their health including their physical, intellectual, sexual or social development.
A woman who is taking hormonal contraceptive should have a yearly visit with her healthcare provider for a blood pressure check and for other indicated healthcare.
5.19 Interference With Laboratory Tests
The use of Medroxyprogesterone acetate may change the results of some laboratory tests, such as coagulation factors, lipids, glucose tolerance, and binding proteins. [See Drug Interactions (7.2)].
6 Adverse Reactions
- The following important adverse reactions observed with the use of Medroxyprogesterone acetate are discussed in greater detail in the Warnings and Precautions section (5):Loss of Bone Mineral Density [see Warnings and Precautions (5.1)]Thromboembolic disease [see Warnings and Precautions (5.2)]Breast Cancer [see Warnings and Precautions (5.3)]Anaphylaxis and Anaphylactoid Reactions [see Warnings and Precautions (5.5)]Bleeding Irregularities [see Warnings and Precautions (5.10)]Weight Gain [see Warnings and Precautions (5.11)]
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies 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.In the two clinical trials with Medroxyprogesterone acetate, over 3,900 women, who were treated for up to 7 years, reported the following adverse reactions, which may or may not be related to the use of Medroxyprogesterone acetate. The population studied ranges in age from 15 to 51 years, of which 46% were White, 50% Non-White, and 4.9% Unknown race. The patients received 150 mg Medroxyprogesterone acetate every 3-months (90 days). The median study duration was 13 months with a range of 1–84 months. Fifty eight percent of patients remained in the study after 13 months and 34% after 24 months.Table 1 Adverse Reactions that Were Reported by More than 5% of SubjectsBody System Body System represented from COSTART medical dictionary.Adverse Reactions [Incidence (%)]Body as a WholeHeadache (16.5%)Abdominal pain/discomfort (11.2%)Metabolic/NutritionalIncreased weight > 10 lbs at 24 months (37.7%)NervousNervousness (10.8%)Dizziness (5.6%)Libido decreased (5.5%)UrogenitalMenstrual irregularities:bleeding (57.3% at 12 months, 32.1% at 24 months)amenorrhea (55% at 12 months, 68% at 24 months)Table 2 Adverse Reactions that Were Reported by between 1 and 5% of SubjectsBody System Body System represented from COSTART medical dictionary.Adverse Reactions [Incidence (%)]Body as a WholeAsthenia/fatigue (4.2%)Backache (2.2%)Dysmenorrhea (1.7%)Hot flashes (1.0%)DigestiveNausea (3.3%)Bloating (2.3%)Metabolic/NutritionalEdema (2.2%)MusculoskeletalLeg cramps (3.7%)Arthralgia (1.0%)NervousDepression (1.5%)Insomnia (1.0%)Skin and AppendagesAcne (1.2%)No hair growth/alopecia (1.1%)Rash (1.1%)UrogenitalLeukorrhea (2.9%)Breast pain (2.8%)Vaginitis (1.2%)Adverse reactions leading to study discontinuation in ≥ 2% of subjects: bleeding (8.2%), amenorrhea (2.1%), weight gain (2.0%)
6.2 Post-Marketing Experience
The following adverse reactions have been identified during post approval use of Medroxyprogesterone acetate. 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.There have been cases of osteoporosis including osteoporotic fractures reported post-marketing in patients taking Medroxyprogesterone acetate.Table 3 Adverse Reactions Reported during Post-Marketing ExperienceBody System Body System represented from COSTART medical dictionary.Adverse ReactionsBody as a WholeChest pain, Allergic reactions including angioedema, Fever, Injection site abscess†, Injection site infection†, Injection site nodule/lump, Injection site pain/tenderness, Injection site persistent atrophy/indentation/dimpling, Injection-site reaction, Lipodystrophy acquired, Chills, Axillary swellingCardiovascularSyncope, Tachycardia, Thrombophlebitis, Deep vein thrombosis, Pulmonary embolus, Varicose veinsDigestiveChanges in appetite, Gastrointestinal disturbances, Jaundice, Excessive thirst, Rectal bleedingHematologic and LymphaticAnemia, Blood dyscrasiaMusculoskeletalOsteoporosisNeoplasms Cervical cancer, Breast cancerNervousParalysis, Facial palsy, Paresthesia, DrowsinessRespiratoryDyspnea and asthma, HoarsenessSkin and AppendagesHirsutism, Excessive sweating and body odor, Dry skin, SclerodermaUrogenitalLack of return to fertility, Unexpected pregnancy, Prevention of lactation, Changes in breast size, Breast lumps or nipple bleeding, Galactorrhea, Melasma, Chloasma, Increased libido, Uterine hyperplasia, Genitourinary infections, Vaginal cysts, Dyspareunia
7.1 Changes In Contraceptive Effectiveness Associated With Co-Administration Of Other Products
- If a woman on hormonal contraceptives takes a drug or herbal product that induces enzymes, including CYP3A4, that metabolize contraceptive hormones, counsel her to use additional contraception or a different method of contraception. Drugs or herbal products that induce such enzymes may decrease the plasma concentrations of contraceptive hormones, and may decrease the effectiveness of hormonal contraceptives. Some drugs or herbal products that may decrease the effectiveness of hormonal contraceptives include:barbituratesbosentancarbamazepinefelbamategriseofulvinoxcarbazepinephenytoinrifampinSt. John's worttopiramate
7.2 Laboratory Test Interactions
- The pathologist should be advised of progestin therapy when relevant specimens are submitted.The following laboratory tests may be affected by progestins including Medroxyprogesterone acetate:(a)Plasma and urinary steroid levels are decreased (e.g., progesterone, estradiol, pregnanediol, testosterone, cortisol).(b)Gonadotropin levels are decreased.(c)Sex-hormone-binding-globulin concentrations are decreased.(d)Protein-bound iodine and butanol extractable protein-bound iodine may increase. T3-uptake values may decrease.(e)Coagulation test values for prothrombin (Factor II), and Factors VII, VIII, IX, and X may increase.(f)Sulfobromophthalein and other liver function test values may be increased.(g)The effects of medroxyprogesterone acetate on lipid metabolism are inconsistent. Both increases and decreases in total cholesterol, triglycerides, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol have been observed in studies.
Medroxyprogesterone acetate should not be administered during pregnancy. [See Contraindications and Warnings and Precautions (5.17).]
8.3 Nursing Mothers
Detectable amounts of drug have been identified in the milk of mothers receiving Medroxyprogesterone acetate. [See Warnings and Precautions (5.13).]
8.4 Pediatric Use
Medroxyprogesterone acetate is not indicated before menarche. Use of Medroxyprogesterone acetate is associated with significant loss of BMD. This loss of BMD is of particular concern during adolescence and early adulthood, a critical period of bone accretion. In adolescents, interpretation of BMD results should take into account patient age and skeletal maturity. It is unknown if use of Medroxyprogesterone acetate by younger women will reduce peak bone mass and increase the risk of osteoporotic fractures in later life. Other than concerns about loss of BMD, the safety and effectiveness are expected to be the same for postmenarchal adolescents and adult women.
8.5 Geriatric Use
This product has not been studied in post-menopausal women and is not indicated in this population.
8.6 Renal Impairment
The effect of renal impairment on Medroxyprogesterone acetate pharmacokinetics has not been studied.
8.7 Hepatic Impairment
The effect of hepatic impairment on Medroxyprogesterone acetate pharmacokinetics has not been studied. Medroxyprogesterone acetate should not be used by women with significant liver disease and should be discontinued if jaundice or disturbances of liver function occur. [See Contraindications (4) and Warnings and Precautions (5.7).]
Medroxyprogesterone acetate contains medroxyprogesterone acetate, a derivative of progesterone, as its active ingredient. Medroxyprogesterone acetate is active by the parenteral and oral routes of administration. It is a white to off-white; odorless crystalline powder that is stable in air and that melts between 200°C and 210°C. It is freely soluble in chloroform, soluble in acetone and dioxane, sparingly soluble in alcohol and methanol, slightly soluble in ether, and insoluble in water.The chemical name for medroxyprogesterone acetate is pregn-4-ene-3,20-dione, 17-(acetyloxy)-6-methyl-, (6α-). The structural formula is as follows:Medroxyprogesterone acetate for intramuscular (IM) injection is available in vials and prefilled syringes, each containing 1 mL of medroxyprogesterone acetate sterile aqueous suspension 150 mg/mL.Each mL contains:Medroxyprogesterone acetate150 mgPolyethylene glycol 335028.9 mgPolysorbate 802.41 mgSodium chloride8.68 mgMethylparaben1.37 mgPropylparaben0.150 mgWater for injectionquantity sufficientWhen necessary, pH is adjusted with sodium hydroxide or hydrochloric acid, or both.
12.1 Mechanism Of Action
Medroxyprogesterone acetate (MPA), when administered at the recommended dose to women every 3 months, inhibits the secretion of gonadotropins which, in turn, prevents follicular maturation and ovulation and results in endometrial thinning. These actions produce its contraceptive effect.
No specific pharmacodynamic studies were conducted with Medroxyprogesterone acetate.
13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility
[See Warnings and Precautions, (5.3, 5.14, and 5.16).]
In five clinical studies using Medroxyprogesterone acetate, the 12-month failure rate for the group of women treated with Medroxyprogesterone acetate was zero (no pregnancies reported) to 0.7 by Life-Table method. The effectiveness of Medroxyprogesterone acetate is dependent on the patient returning every 3 months (13 weeks) for reinjection.
14.2 Bone Mineral Density (Bmd) Changes In Adult Women
In a controlled, clinical study, adult women using Medroxyprogesterone acetate for up to 5 years showed spine and hip BMD mean decreases of 5–6%, compared to no significant change in BMD in the control group. The decline in BMD was more pronounced during the first two years of use, with smaller declines in subsequent years. Mean changes in lumbar spine BMD of -2.86%, -4.11%, -4.89%, -4.93% and -5.38% after 1, 2, 3, 4, and 5 years, respectively, were observed. Mean decreases in BMD of the total hip and femoral neck were similar.After stopping use of Medroxyprogesterone acetate (150 mg), there was partial recovery of BMD toward baseline values during the 2-year post-therapy period. Longer duration of treatment was associated with less complete recovery during this 2-year period following the last injection. Table 4 shows the change in BMD in women after 5 years of treatment with Medroxyprogesterone acetate and in women in a control group, as well as the extent of recovery of BMD for the subset of the women for whom 2-year post treatment data were available.Table 4.

The impact of Medroxyprogesterone acetate (150 mg) use for up to 240 weeks (4.6 years) was evaluated in an open-label non-randomized clinical study in 389 adolescent females (12–18 years). Use of Medroxyprogesterone acetate was associated with a significant decline from baseline in BMD.Partway through the trial, drug administration was stopped (at 120 weeks). The mean number of injections per Medroxyprogesterone acetate user was 9.3. The decline in BMD at total hip and femoral neck was greater with longer duration of use (see Table 5). The mean decrease in BMD at 240 weeks was more pronounced at total hip (-6.4%) and femoral neck (-5.4%) compared to lumbar spine (-2.1%).In general, adolescents increase bone density during the period of growth following menarche, as seen in the untreated cohort. However, the two cohorts were not matched at baseline for age, gynecologic age, race, BMD and other factors that influence the rate of acquisition of bone mineral density.Table 5.

14.4 Relationship Of Fracture Incidence To Use Of Dmpa 150 Mg Im Or Non-Use By Women Of Reproductive Age
A retrospective cohort study to assess the association between DMPA injection and the incidence of bone fractures was conducted in 312,395 female contraceptive users in the UK. The incidence rates of fracture were compared between DMPA users and contraceptive users who had no recorded use of DMPA. The Incident Rate Ratio (IRR) for any fracture during the follow-up period (mean = 5.5 years) was 1.41 (95% CI 1.35, 1.47). It is not known if this is due to DMPA use or to other related lifestyle factors that have a bearing on fracture rate.In the study, when cumulative exposure to DMPA was calculated, the fracture rate in users who received fewer than 8 injections was higher than that in women who received 8 or more injections. However, it is not clear that cumulative exposure, which may include periods of intermittent use separated by periods of non-use, is a useful measure of risk, as compared to exposure measures based on continuous use.There were very few osteoporotic fractures (fracture sites known to be related to low BMD) in the study overall, and the incidence of osteoporotic fractures was not found to be higher in DMPA users compared to non-users. Importantly, this study could not determine whether use of DMPA has an effect on fracture rate later in life.

Patient InformationMedroxyprogesterone acetate(medroxyprogesterone acetate injectable suspension)Contraceptive InjectionRead this Patient Information carefully before you decide if Medroxyprogesterone acetate is right for you. This information does not take the place of talking with your gynecologist or other healthcare provider who specializes in women’s health. If you have any questions about Medroxyprogesterone acetate, ask your healthcare provider. You should also learn about other birth control methods to choose the one that is best for you.What is the most important information I should know about Medroxyprogesterone acetate?Medroxyprogesterone acetate can cause serious side effects, including:• Use of Medroxyprogesterone acetate may cause you to lose calcium stored in your bone and decrease your bone mass. The longer you use Medroxyprogesterone acetate, the greater your loss of calcium from your bones. Your bones may not recover completely when you stop using Medroxyprogesterone acetate.• If you use Medroxyprogesterone acetate continuously for a long time (for more than 2 years), it may increase the risk of weak, porous bones (osteoporosis) that could increase the risk of broken bones, especially after menopause.• You should not use Medroxyprogesterone acetate for more than two years unless you cannot use other birth control methods.• It is not known if your risk of developing osteoporosis is greater if you are a teenager or young adult when you start to use Medroxyprogesterone acetate (see “What are the possible side effects of Medroxyprogesterone acetate?”).Medroxyprogesterone acetate is intended to prevent pregnancy. Medroxyprogesterone acetate does not protect against HIV infection (AIDS) and other sexually transmitted diseases (STDs).What is Medroxyprogesterone acetate?Medroxyprogesterone acetate is a progestin hormone birth control method that is given by injection (a shot) to prevent pregnancy.How well does Medroxyprogesterone acetate work?Your chance of getting pregnant depends on how well you follow the directions for taking your Medroxyprogesterone acetate. The more carefully you follow the directions (such as returning every 3 months for your next injection), the less chance you have of getting pregnant.In clinical studies, about 1 out of 100 women got pregnant during the first year that they used Medroxyprogesterone acetate.The following chart shows the chance of getting pregnant for women who use different methods of birth control. Each box on the chart contains a list of birth control methods that are similar in effectiveness. The most effective methods are at the top of the chart. The box on the bottom of the chart shows the chance of getting pregnant for women who do not use birth control and are trying to get pregnant.How should I take Medroxyprogesterone acetate?Medroxyprogesterone acetate is given by your healthcare provider as a shot into your muscle (intramuscular injection). The shot is given in your buttock or upper arm 1 time every 3 months. At the end of the 3 months, you will need to return to your healthcare provider for your next injection in order to continue your protection against pregnancy.•To make sure that you are not pregnant before you take Medroxyprogesterone acetate,the first injection should be given only: o during the first 5 days of a normal menstrual period, or o within the first 5 days after giving birth, if you are not breastfeeding, or o at the 6th week after giving birth, if you are feeding your baby only breastmilk.•Medroxyprogesterone acetate may be given at other times than those listed above, but you will likely need to have a pregnancy test first to show that you are not pregnant•During treatment with Medroxyprogesterone acetate, you should see your healthcare provider every year for a blood pressure check and other healthcare needs.Who Should Not Use Medroxyprogesterone acetate?Do not use Medroxyprogesterone acetate if you:• are pregnant or think you might be pregnant• have bleeding from your vagina that has not been explained• have breast cancer now or in the past, or think you have breast cancer• have had a stroke• ever had blood clots in your arms, legs or lungs• have problems with your liver or liver disease• are allergic to medroxyprogesterone acetate or any of the other ingredients in Medroxyprogesterone acetate. See the end of this leaflet for a complete list of ingredients in Medroxyprogesterone acetate.What should I tell my healthcare provider before taking Medroxyprogesterone acetate?Before taking Medroxyprogesterone acetate, tell your healthcare provider if you have:• risk factors for weak bones (osteoporosis) such as bone disease, use alcohol or smoke regularly, anorexia nervosa, or a strong family history of osteoporosis• irregular or lighter than usual menstrual periods• breast cancer now or in the past, or think you have breast cancer• a family history of breast cancer• an abnormal mammogram (breast X-ray), lumps in your breasts, or bleeding from your nipples• kidney problems• high blood pressure• had a stroke• had blood clots in your arms, legs or lungs• migraine headaches• asthma• epilepsy (convulsions or seizures)• diabetes• depression or a history of depression• any other medical conditionsIf you are breastfeeding or plan to breastfeed, Medroxyprogesterone acetate can pass into your breast milk. Talk to your healthcare provider about the best way to feed your baby if you take Medroxyprogesterone acetate.Tell your healthcare provider about all of the medicines you take, including prescription and nonprescription medicines, vitamins, and herbal supplements.Medroxyprogesterone acetate and certain other medicines may affect each other, causing serious side effects. Sometimes the doses of other medicines may need to be changed while you are taking Medroxyprogesterone acetate.Some medicines may make Medroxyprogesterone acetate less effective at preventing pregnancy, including those listed below.Especially tell your healthcare provider if you take:• medicine to help you sleep• bosentan• medicine for seizures• griseofulvin• an antibiotic• medicine for HIV (AIDS)• St. John’s wortKnow the medicines you take. Keep a list of your medicines with you to show your healthcare provider or pharmacist before you first start taking Medroxyprogesterone acetate or when you get a new medicine.Follow your healthcare provider’s instructions about using a back-up method of birth control if you are taking medicines that may make Medroxyprogesterone acetate less effective.What are the possible side effects of Medroxyprogesterone acetate?Medroxyprogesterone acetate can cause serious side effects, including: • Effect on the bones: See “What is the most important information I should know aboutMedroxyprogesterone acetate?”.Teenage years are the most important years to gain bone strength. The decrease in calcium inyour bones is of most concern if you are a teenager or have the following problems: • bone disease • an eating disorder (anorexia nervosa) • a strong family history of osteoporosis • you take a drug that can lower the amount of calcium in your bones (drugs for epilepsy or steroid drugs) • you drink a lot of alcohol (more than 2 drinks a day) • you smokeIf you need a birth control method for more than 2 years, your healthcare provider may switch you to another birth control method instead of using Medroxyprogesterone acetate. If you continue using Medroxyprogesterone acetate, your healthcare provider may ask you to have a bone test, especially if you have other risks for weak bones.When Medroxyprogesterone acetate is stopped, your bones may start to regain calcium. However, in a study of teenage girls who used Medroxyprogesterone acetate for more than 2 years, their hip bones did not completely recover by 5 years after they stopped using Medroxyprogesterone acetate. Taking calcium and Vitamin D and exercising daily may lessen the loss of calcium from your bones.• possible increased risk of breast cancer. Women who use Medroxyprogesterone acetate may have a slightly increased risk of breast cancer compared to non-users.• blood clots in your arms, legs, lungs, and eyes• stroke• a pregnancy outside of the uterus (ectopic pregnancy). Ectopic pregnancy is a medical emergency that often requires surgery. Ectopic pregnancy can cause internal bleeding, infertility, and even death.• allergic reactions. Severe allergic reactions have been reported in some women using Medroxyprogesterone acetate.• loss of vision or other eye problems• migraine headaches• depression• convulsions or seizures• liver problemsCall your healthcare provider right away if you have:• sharp chest pain, coughing up blood, or sudden shortness of breath (indicating a possible clot in the lung)• sudden severe headache or vomiting, dizziness or fainting, problems with your eyesight or speech, weakness, or numbness in an arm or leg (indicating a possible stroke)• severe pain or swelling in the calf (indicating a possible clot in the leg)• sudden blindness, partial or complete (indicating a possible clot in the blood vessels of the eye)• unusually heavy vaginal bleeding• severe pain or tenderness in the lower abdominal area• persistent pain, pus, or bleeding at the injection site• yellowing of the eyes or skin• hives• difficulty breathing• swelling of the face, mouth, tongue or neckThe most common side effects of Medroxyprogesterone acetate include:• irregular vaginal bleeding, such as lighter or heavier menstrual bleeding, or continued spotting• weight gain. You may experience weight gain while you are using Medroxyprogesterone acetate. About two-thirds of the women who used Medroxyprogesterone acetate in the clinical trials reported a weight gain of about 5 pounds during the first year of use. You may continue to gainweight after the first year. Women who used Medroxyprogesterone acetate for 2 years gained an average of 8 pounds over those 2 years.• abdominal pain• headache• weakness• tiredness• nervousness• dizzinessTell your healthcare provider if you have any side effect that bothers you or does not go away.These are not all the possible side effects of Medroxyprogesterone acetate. For more information, ask your healthcare provider or pharmacist.Call your healthcare provider for medical advice about side effects. You may report side effects to FDA at 1- 800-FDA-1088.What other information should I consider before choosing Medroxyprogesterone acetate?• Pregnancy. When you take Medroxyprogesterone acetate every 3 months, your chance of getting pregnant is very low. You could miss a period or have a light period and not be pregnant. If you miss 1 or 2 periods and think you might be pregnant, see your healthcare provider as soon aspossible. You should not use Medroxyprogesterone acetate if you are pregnant. However, Medroxyprogesterone acetate taken by accident during pregnancy does not seem to cause birth defects.• Nursing Mothers. Although Medroxyprogesterone acetate can be passed to the nursing baby in the breast milk, no harmful effects on babies have been found. Medroxyprogesterone acetate does not stop the breasts from producing milk, so it can be used by nursing mothers. However,to minimize the amount of Medroxyprogesterone acetate that is passed to the baby in the first weeks after birth, you should wait until your baby is 6 weeks old before you start using Medroxyprogesterone acetate for birth control.How will Medroxyprogesterone acetate change my periods?• Change in normal menstrual cycle. The side effect reported most frequently by women who use Medroxyprogesterone acetate for birth controls is a change in their normal menstrual cycle. During the first year of using Medroxyprogesterone acetate, you might have one or more of the following changes: o irregular or unpredictable bleeding or spotting, o an increase or decrease in menstrual bleeding o no bleeding at all. In clinical studies of Medroxyprogesterone acetate, 55% of women reported no menstrual bleeding (amenorrhea) after one year of use and 68% of women reported no menstrual bleeding after two years of use.• Missed period: During the time you are using Medroxyprogesterone acetate for birth controls, you may skip a period, or your periods may stop completely. If you have been receiving your shot of Medroxyprogesterone acetate regularly every 3 months, then you are probably not pregnant.However, if you think that you may be pregnant, see your healthcare provider.Unusually heavy or continuous bleeding is not a usual effect of Medroxyprogesterone acetate and if this happens you should see your healthcare provider right away.With continued use of Medroxyprogesterone acetate, bleeding usually decreases and many women stop having periods completely. When you stop using Medroxyprogesterone acetate your menstrual period will usually, in time, return to its normal cycle.What if I want to become pregnant?Because Medroxyprogesterone acetate is a long-acting birth control method, it takes some time after your last shot for its effect to wear off. Most women who try to get pregnant after using Medroxyprogesterone acetate get pregnant within 18 months after their last shot. The length of time you use Medroxyprogesterone acetate has no effect on how long it takes you to become pregnant after you stop using it.General Information about Medroxyprogesterone acetateMedicines are sometimes prescribed for conditions that are not mentioned in patient information leaflets. This leaflet summarizes the most important information about Medroxyprogesterone acetate. If you would like more information, talk with your healthcare provider. You can ask your healthcare provider for information about Medroxyprogesterone acetate that is written for healthcare providers.What are the ingredients in Medroxyprogesterone acetate?Active ingredient: medroxyprogesterone acetateInactive ingredients: polyethylene glycol 3350, polysorbate 80, sodium chloride, methylparaben, propylparaben, and water for injection.
