🩺 Clinical
Medroxyprogesterone injection is used to prevent pregnancy and to treat endometriosis (a condition in which the type of tissue that lines the uterus (womb) grows in other areas of the body and causes pain, heavy or irregular menstruation [periods], and other symptoms). Medroxyprogesterone is in a class of medications called progestins. It works to prevent pregnancy by preventing ovulation (the release of eggs from the ovaries). Medroxyprogesterone also thins the lining of the uterus which helps to prevent pregnancy in all women and slows the spread of tissue from the uterus to other parts of t...

🚨 Boxed Warning ▾
WARNING: LOSS OF BONE MINERAL DENSITY Women who use medroxyprogesterone acetate injectable suspension may lose significant bone mineral density. Bone loss is greater with increasing duration of use and may not be completely reversible [see Warnings and Precautions (5.1) ]. It is unknown if use of medroxyprogesterone acetate injectable suspension 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 [see Warnings and Precautions (5.1) ].
Medroxyprogesterone acetate injectable suspension is not recommended as a long-term (i.e., longer than 2 years) birth control method unless other options are considered inadequate [see Indications and Usage (1) and Warnings and Precautions (5.1) ]. WARNING: LOSS OF BONE MINERAL DENSITY See full prescribing information for complete boxed warning . Women who use medroxyprogesterone acetate injectable suspension may lose significant bone mineral density.

🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE Medroxyprogesterone acetate injectable suspension is indicated for use by females of reproductive potential to prevent pregnancy. Limitations of Use : The use of medroxyprogesterone acetate injectable suspension is not recommended as a long-term (i.e., longer than 2 years) birth control method unless other options are considered inadequate [see Dosage and Administration (2.1) and Warnings and Precautions (5.1) ]. Medroxyprogesterone acetate injectable suspension is a progestin indicated for use by females of reproductive potential to prevent pregnancy.
( 1 ) Limitations of Use : The use of medroxyprogesterone acetate injectable suspension is not recommended as a long-term (i.e., longer than 2 years) birth control method unless other options are considered inadequate. ( 1 , 5.1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION The recommended dose is 150 mg of medroxyprogesterone acetate injectable suspension every 3 months (13 weeks) administered by deep, intramuscular (IM) injection in the gluteal or deltoid muscle. ( 2.1 )
2.1Prevention of Pregnancy Both the 1 mL vial and the 1 mL prefilled syringe of medroxyprogesterone acetate injectable suspension 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 injectable suspension 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.
Use for longer than 2 years is not recommended (unless other birth control methods are considered inadequate) due to the impact of long-term medroxyprogesterone acetate injectable suspension treatment on bone mineral density (BMD) [see Warnings and Precautions (5.1) ] . 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 ONLY during the first 5 days of a normal menstrual period or within the first 5-days post-partum.
In post-partum mothers who exclusively breastfeed, administer medroxyprogesterone acetate injectable suspension during or after the sixth post-partum 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 injectable suspension depends on adherence to the dosage schedule of administration.
2.2Switching from Other Methods of Contraception When switching from other contraceptive methods, medroxyprogesterone acetate injectable suspension 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 injectable suspension on the day after the last active tablet or at the latest, on the day following the final inactive tablet).

5.1Loss of Bone Mineral Density Use of medroxyprogesterone acetate injectable suspension 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 injectable suspension by younger women will reduce peak bone mass and increase the risk for osteoporotic fracture in later life.
A study to assess the reversibility of loss of BMD in adolescents was conducted with medroxyprogesterone acetate injectable suspension. After discontinuing medroxyprogesterone acetate injectable suspension in these adolescents, mean BMD loss at the total hip and femoral neck did not fully recover by 5 years (60 months) post-treatment in the sub-group of adolescents who were treated for more than 2 years [see Clinical Studies (14.3) ] . Similarly, in adults, there was only partial recovery of mean BMD at the total hip, femoral neck, and lumbar spine towards baseline by 2 years post-treatment [see Clinical Studies (14.2) ] .
The use of medroxyprogesterone acetate injectable suspension is not recommended as a long-term (i.e., longer than 2 years) birth control method unless other options are considered inadequate. BMD should be evaluated when a woman needs to continue to use medroxyprogesterone acetate injectable suspension 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 injectable suspension in women with osteoporosis risk factors. Medroxyprogesterone acetate injectable suspension 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).
5.2Thromboembolic Disorders There have been reports of serious thrombotic events in women using medroxyprogesterone acetate injectable suspension (150 mg). However, medroxyprogesterone acetate injectable suspension has not been causally associated with the induction of thrombotic or thromboembolic disorders. Any patient who develops thrombosis while undergoing therapy with medroxyprogesterone acetate injectable suspension should discontinue treatment unless she has no other acceptable options for birth control.
Do not re-administer medroxyprogesterone acetate injectable suspension 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 re-administer if examination reveals papilledema or retinal vascular lesions.

6.1Clinical Trials Experience Clinical trials are conducted under widely varying conditions; therefore, 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 injectable suspension, 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 injectable suspension.
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 injectable suspension every 3-months (90 days). The median study duration was 13 months with a range of 1 to 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 Subjects * Body System represented from COSTART medical dictionary.
Body System* Adverse Reactions [Incidence (%)] Body as a Whole Headache (16.5%) Abdominal pain/discomfort (11.2%) Metabolic/Nutritional Increased weight >10 lb at 24 months (37.7%) Nervous Nervousness (10.8%) Dizziness (5.6%) Libido decreased (5.5%) Reproductive (Urogenital*) Menstrual irregularities: bleeding (57.3% at 12 months, 32.1% at 24 months) amenorrhea (55% at 12 months, 68% at 24 months) Table 2.

6.2Post-Marketing Experience The following adverse reactions have been identified during post approval use of medroxyprogesterone acetate injectable suspension. 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 injectable suspension.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Drugs or herbal products that induce certain enzymes, including CYP3A4, may decrease the effectiveness of contraceptive drug products. Counsel patients to use a back-up method or alternative method of contraception when enzyme inducers are used with medroxyprogesterone acetate injectable suspension. ( 7.1 )
7.1Changes 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: barbiturates bosentan carbamazepine felbamate griseofulvin oxcarbazepine phenytoin rifampin St.
John’s wort topiramate 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.
7.2Laboratory 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 injectable suspension: (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. T 3 -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.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: Discontinue if pregnancy occurs. ( 8.1 ) Lactation: Detectable amounts of drug have been identified in the milk of mothers receiving Medroxyprogesterone acetate injectable suspension. ( 8.2 ) Pediatric Patients: Medroxyprogesterone acetate injectable suspension is not indicated before menarche. ( 8.4 )
8.1Pregnancy Risk Summary There is no use for contraception in pregnancy; therefore, medroxyprogesterone acetate injectable suspension should be discontinued during pregnancy. Epidemiologic studies and meta-analyses have not found an increased risk of genital or non-genital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to progestins before conception or during early pregnancy. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
8.2Lactation Risk Summary Although medroxyprogesterone acetate is detectable in the milk of mothers receiving medroxyprogesterone acetate injectable suspension, milk composition, quality, and amount do not appear to be adversely affected. Effects on milk production and lactation initiation/duration remain unclear when administered before 6 weeks after delivery, therefore, in mothers who exclusively breastfeed, initiate medroxyprogesterone acetate injectable suspension during or after the sixth post-partum week [see Dosage and Administration (2.1) ].
No adverse effects in breastfed infants would be expected with maternal use of progestins. Neonates and infants exposed to medroxyprogesterone acetate from breast milk have been studied and no adverse effects have been noted. The developmental and health benefits of breast-feeding should be considered along with the mother’s clinical need for medroxyprogesterone acetate injectable suspension and any potential adverse effects on the breastfed child from medroxyprogesterone acetate injectable suspension or from the underlying maternal condition.
8.3Females and Males of Reproductive Potential Medroxyprogesterone acetate injectable suspension is indicated for the prevention of pregnancy and would therefore be expected to impair female fertility until cessation of treatment. Women may experience a delay in return to ovulation and fertility (conception) following discontinuation of medroxyprogesterone acetate injectable suspension [see Warnings and Precautions (5.15) ] .
8.4Pediatric Use Medroxyprogesterone acetate injectable suspension is not indicated before menarche. Use of medroxyprogesterone acetate injectable suspension 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 injectable suspension 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.

These actions contribute to its contraceptive effect.
12.2Pharmacodynamics No specific pharmacodynamic studies were conducted with medroxyprogesterone acetate injectable suspension.
12.3Pharmacokinetics Absorption Following a single 150 mg IM dose of medroxyprogesterone acetate injectable suspension 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. Distribution Plasma protein binding of MPA averages 86%. MPA binding occurs primarily to serum albumin.
No binding of MPA occurs with sex-hormone-binding globulin (SHBG). Elimination Metabolism MPA 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.
Excretion The 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 injectable suspension is approximately 50 days. Most medroxyprogesterone acetate metabolites are excreted in the urine as glucuronide conjugates with only minor amounts excreted as sulfates.
Specific Populations The effect of hepatic and/or renal impairment on the pharmacokinetics of medroxyprogesterone acetate injectable suspension is unknown.
