Depo-SubQ Provera

1 INDICATIONS AND USAGE Depo-subQ provera 104 is indicated in females of reproductive age for: • Prevention of pregnancy and • Management of endometriosis-associated pain. Depo-subQ provera 104 is a progestin that is indicated in females of reproductive age for: • Prevention of pregnancy. ( 1 ) • Management of endometriosis-associated pain. ( 1 ) Limitations of Use : Use of depo-subQ provera 104 is not recommended as a long-term (i.e., longer than 2 years) birth control method or medical therapy for endometriosis-associated pain unless other options are considered inadequate. ( 1 , 5.1 ) Limitations of Use : The use of depo-subQ provera 104 is not recommended as a long-term (i.e., longer than 2 years) birth control method or medical therapy for endometriosis-associated pain unless other options are considered inadequate [see Dosage and Administration (2.1) and Warnings and Precautions (5.1) ].

2 DOSAGE AND ADMINISTRATION • Only for healthcare professional administration. ( 2.1 ) • Prior to first injection, confirm the patient is not pregnant. ( 2.1 ) • Administer 104 mg of depo-subQ provera 104 by subcutaneous injection into the anterior thigh or abdomen, once every 12 to 14 weeks. ( 2.1 ) • See Full Prescribing Information for recommendations on switching from another contraceptive method to depo-subQ provera 104. ( 2.2 ) • See Full Prescribing Information for important preparation and administration instructions. ( 2.3 ) 2.1 Important Dosage and Administration Instructions Depo-subQ provera 104 is only for subcutaneous administration and is only to be administered by a healthcare professional. Use for longer than 2 years is not recommended (unless other birth control methods or medical therapies for endometriosis-associated pain are considered inadequate) due to the impact of long-term depo-subQ provera 104 treatment on bone mineral density (BMD) [see Warnings and Precautions (5.1) ] . Prior to the first injection confirm that the patient is not pregnant. For women who are sexually active and who have regular menses, administer the first injection only during the first 5 days of a normal menstrual period. For women who are breast-feeding, administer the first injection during or after the sixth post-partum week. The recommended dosage of depo-subQ provera 104 is 104 mg given subcutaneously every 12 to 14 weeks. If more than 14 weeks elapse between injections, confirm that the patient is not pregnant before the next injection. Instruct the patient that if they are unable to receive an injection within 12–14 weeks, another contraceptive method should be used until the next depo-subQ provera 104 injection. The dosage does not need to be adjusted for body weight. Inject the entire contents of the pre-filled syringe using strict aseptic technique into the upper anterior thigh or abdomen, rotating the sites with every injection [see Dosage and Administration (2.3) ] . 2.2 Switching from Another Method of Contraception When switching from another contraceptive method to depo-subQ provera 104, administer depo-subQ provera 104 in a manner that ensures continuous contraceptive coverage. Follow the respective recommendations when switching from the contraceptive methods listed below: • Combined hormonal contraceptives : administer the first injection of depo-subQ provera 104 within 7 days after the last day of using the combined hormonal contraceptive method (i.e., within 7 days after taking the last active pill). • An implant : administer the first injection of depo-subQ provera 104 on the day of implant removal. • A contraceptive vaginal ring or transdermal system : administer the first injection of depo-subQ provera 104 on the day the patient would have inserted the next ring or applied the next transdermal system. • An Intrauterine Device (IUD) or Intrauterine System (IUS) : administer the first injection of depo-subQ provera 104 on the day of IUD/IUS removal. If the IUD/IUS is not removed on the first day of the patient's menstrual cycle, instruct patients to use a non-hormonal back-up method of birth control for the first 7 days after administration of depo-subQ provera 104. • Depot medroxyprogesterone acetate injectable suspension for intramuscular use (DMPA-IM) : inject depo-subQ provera 104 12 to 14 weeks after the last dose of DMPA-IM. 2.3 Preparation and Administration Instructions Prior to injection: • Ensure all the components in Figure A are available and that depo-subQ provera 104 is at room temperature . • Shake the pre-filled syringe vigorously prior to injection to ensure appropriate viscosity of the suspension. • Inspect depo-subQ provera 104 visually for particulate matter and discoloration. Figure A. Components in the Package Step 1: Select & Prepare the Injection Area • Select a preferred injection area, i.e., the left or right upper thigh or the abdomen (see shaded areas , Figure B ). • Avoid selection…

5 WARNINGS AND PRECAUTIONS • Thromboembolic disorders: Discontinue depo-subQ provera 104 in patients who develop arterial or venous thrombosis. ( 5.2 ) • Breast cancer risks: Monitor women with a family history of breast cancer or a significant risk of breast cancer carefully. ( 5.3 ) • Meningioma: Discontinue depo-subQ provera 104 if meningioma is diagnosed. Monitor patients for signs and symptoms of meningioma. ( 5.4 ) • Ectopic pregnancy: Consider ectopic pregnancy if a woman becomes pregnant or complains of severe abdominal pain. ( 5.5 ) • Anaphylaxis: Provide emergency medical treatment. ( 5.6 ) • Injection site reactions (e.g., persistent atrophy, dimpling/indentation, lump/nodule and discoloration) have been reported. ( 5.11 ) • Diabetics may be at greater risk of hyperglycemia. ( 5.13 ) • Jaundice and elevated transaminase: Discontinue depo-subQ provera 104 if jaundice or elevated transaminase levels develop. ( 5.14 ) 5.1 Loss of Bone Mineral Density Use of depo-subQ provera 104 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 depo-subQ provera 104 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 DMPA-IM. After discontinuing DMPA-IM 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 (14.4) ] . 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 (14.3) ] . The use of depo-subQ provera 104 is not recommended as a long-term (i.e., longer than 2 years) birth control method or medical therapy for endometriosis-associated pain unless other options are considered inadequate. BMD should be evaluated when a woman needs to continue to use depo-subQ provera 104 long-term. In adolescents, interpretation of BMD results should take into account patient age and skeletal maturity. Other birth control methods or therapies for endometriosis-associated pain should be considered in the risk/benefit analysis for the use of depo-subQ provera 104 in women with osteoporosis risk factors. Depo-subQ provera 104 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). 5.2 Arterial and Venous Thromboembolic Disorders There have been reports of serious arterial and venous thrombotic events in women treated with DMPA-IM. Women with a history of thromboembolic disorders were not studied in clinical trials of depo-subQ provera 104. Although no causal relationship between the use of depo-subQ provera 104 and thrombotic events has been clearly established, patients who develop arterial or venous thrombosis while taking depo-subQ provera 104 should discontinue treatment. Do not re-administer depo-subQ provera 104 pending examination if there is a sudden onset of a suspected vascular ocular event (e.g., partial or complete loss of vision, proptosis, or diplopia) or migraine. Do not re-administer depo-subQ provera 104 if examination reveals papilledema or retinal vascular lesions. 5.3 Cancer Risks Breast Cancer The use of hormonal contraceptives, including depo sub-Q provera 104, is contraindicated in women who have or have had breast cancer because breast cancer may be sensitive to hormones [see Contraindications (4) ] . Women who have a family history of breast cancer or a significant risk of br…

4 CONTRAINDICATIONS The use of depo-subQ provera 104 is contraindicated in the following conditions: • Active thrombophlebitis, or current or history of thromboembolic disorders, or cerebral vascular disease [see Warnings and Precautions (5.2) ] . • Known, suspected, or past malignancy of the breast [see Warnings and Precautions (5.3) ] . • Significant liver disease [see Warnings and Precautions (5.14) ] . • Known hypersensitivity to medroxyprogesterone acetate or any of the ingredients in depo-subQ provera 104 [see Warnings and Precautions (5.6) ] . • Undiagnosed vaginal bleeding [see Warnings and Precautions (5.12) ] . • Active thrombophlebitis, or current or history of thromboembolic disorders, or cerebral vascular disease. ( 4 ) • Known, suspected, or past malignancy of the breast. ( 4 ) • Significant liver disease. ( 4 ) • Known hypersensitivity to medroxyprogesterone acetate or any of the ingredients of depo-subQ provera 104. ( 4 ) • Undiagnosed vaginal bleeding. ( 4 )

7 DRUG INTERACTIONS Strong CYP3A inhibitors and inducers: Avoid concomitant use. ( 7 ) 7.1 Effect of Other Drugs on depo-SubQ provera 104 Moderate or Strong CYP3A Inducers Concomitant use with moderate or strong CYP3A inducers may decrease concentrations of medroxyprogesterone acetate which may reduce depo-subQ provera 104 efficacy. This effect is based upon the primary metabolism of medroxyprogesterone acetate by CYP3A and was not confirmed by a clinical study. Avoid coadministration of depo-subQ provera 104 with moderate or strong CYP3A inducers. Some examples of moderate CYP3A inducers are bosentan, efavirenz, etravirine, and modafinil. Some examples of strong CYP3A inducers are rifampin, carbamazepine, phenytoin, phenobarbital, mitotane, and St. John's wort (the CYP3A4 induction effect of St. John's wort varies widely and is preparation dependent). These examples are a guide and do not represent a comprehensive list of all possible drugs that may fit these categories. The use of CYP3A inducers may require using a back-up or alternate contraceptive method.

8.1 Pregnancy Risk Summary There is no use for contraception in pregnancy; therefore, depo-subQ provera 104 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 2-4% and 15‑20%, respectively.

6 ADVERSE REACTIONS The following important adverse reactions are described in more detail in other sections of the prescribing information: • Loss of bone mineral density [see Warnings and Precautions (5.1) ] • Arterial and venous thromboembolic disorders [see Warnings and Precautions (5.2) ] • Anaphylaxis [see Warnings and Precautions (5.6) ] • Fluid retention [see Warnings and Precautions (5.7) ] • Delayed return of ovulation or fertility [see Warnings and Precautions (5.9) ] • Depression [see Warnings and Precautions (5.10) ] • Injection site reactions [see Warnings and Precautions (5.11) ] • Bleeding irregularities [see Warnings and Precautions (5.12) ] Most common adverse reactions (incidence >5%) are dysfunctional uterine bleeding, headache, increased weight, amenorrhea, and injection site reactions. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Pfizer Inc. at 1-800-438-1985 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Clinical trials are conducted under widely varying conditions, therefore 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 depo-subQ provera 104 in five clinical trials involving 2325 women including 2043 women who received treatment for contraception (1780 treated up to 1 year and 263 treated for up to 2 years) and 282 women for endometriosis for up to 6 months. In these pooled trials, 9% of women discontinued treatment due to an adverse reaction and the most common reason for discontinuation was dysfunctional uterine bleeding (3%). Adverse Reactions in the Contraception Adult Studies Table 1 presents frequently reported adverse reactions (>1%) in the contraception pooled studies. In these studies, the most frequently reported adverse reactions (>5%) were dysfunctional uterine bleeding (e.g., irregular, increased, decreased, or spotting), headache, increased weight, amenorrhea, and injection site reactions (e.g., pain/tenderness, nodule/lump, persistent atrophy/indentation/dimpling or lipodystrophy). The frequency reported is based on the all-causality incidence in the pooled results of the three contraception studies. Closely related "Adverse Reaction" terms were grouped but individual patients reporting two or more grouped events were only counted once. Table 1. Frequently Reported Adverse Reactions in the Contraception Studies (>1%) Adverse Reaction Frequency Dysfunctional uterine bleeding (irregular, increase, decrease, spotting) 18% Headache 9% Increased weight (see below) 7% Amenorrhea 6% Injection site reactions (such as pain/tenderness, nodule/lump, persistent atrophy/indentation/dimpling, lipodystrophy, discoloration) 6% Vaginitis, including candidiasis and bacterial 5% Abdominal pain 4% Urinary tract infections 4% Acne 4% Depression 3% Decreased libido 3% Nausea 3% Back pain 3% Breast pain/tenderness 2% Fatigue 2% Anxiety 1% Irritability 1% Dizziness 1% Dysfunctional Uterine Bleeding The extent of bleeding and spotting in the three contraception trials is presented in Figure N; data from the endometriosis trials are presented in Figure O [see Warnings and Precautions (5.1) ].
