drospirenone and ethinyl estradiol

1 INDICATIONS AND USAGE Drospirenone and ethinyl estradiol tablets are a combination of drospirenone, a progestin, and ethinyl estradiol, an estrogen, indicated for use by females of reproductive potential to: • Prevent pregnancy. ( 1.1 ) • Treat symptoms of premenstrual dysphoric disorder (PMDD) for females of reproductive potential who choose to use an oral contraceptive for contraception. ( 1.2 ) • Treat moderate acne for women at least 14 years old only if the patient desires an oral contraceptive for birth control. ( 1.3 ) 1.1 Oral Contraceptive Drospirenone and ethinyl estradiol tablets are indicated for use by females of reproductive potential to prevent pregnancy. 1.2 Premenstrual Dysphoric Disorder (PMDD) Drospirenone and ethinyl estradiol tablets are also indicated for the treatment of symptoms of premenstrual dysphoric disorder (PMDD) in females of reproductive potential who choose to use an oral contraceptive as their method of contraception. The effectiveness of drospirenone and ethinyl estradiol tablets for PMDD when used for more than three menstrual cycles has not been evaluated. The essential features of PMDD according to the Diagnostic and Statistical Manual-4th edition (DSM-IV) include markedly depressed mood, anxiety or tension, affective lability, and persistent anger or irritability. Other features include decreased interest in usual activities, difficulty concentrating, lack of energy, change in appetite or sleep, and feeling out of control. Physical symptoms associated with PMDD include breast tenderness, headache, joint and muscle pain, bloating and weight gain. In this disorder, these symptoms occur regularly during the luteal phase and remit within a few days following onset of menses; the disturbance markedly interferes with work or school, or with usual social activities and relationships with others. Diagnosis is made by healthcare providers according to DSM-IV criteria, with symptomatology assessed prospectively over at least two menstrual cycles. In making the diagnosis, care should be taken to rule out other cyclical mood disorders. Drospirenone and ethinyl estradiol tablets has not been evaluated for the treatment of premenstrual syndrome (PMS). 1.3 Acne Drospirenone and ethinyl estradiol tablets are indicated for the treatment of moderate acne vulgaris in women at least 14 years of age, who have no known contraindications to oral contraceptive therapy and have achieved menarche. Drospirenone and ethinyl estradiol tablets should be used for the treatment of acne only if the patient desires an oral contraceptive for birth control.

2 DOSAGE AND ADMINISTRATION • Take one tablet daily by mouth at the same time every day. ( 2.1 ) • Tablets must be taken in the order directed on the blister pack. ( 2.1 ) 2.1 How to Take Drospirenone and Ethinyl Estradiol Tablets Take one tablet by mouth at the same time every day. The failure rate may increase when pills are missed or taken incorrectly. To achieve maximum contraceptive and PMDD effectiveness, drospirenone and ethinyl estradiol tablets must be taken exactly as directed, in the order directed on the blister pack. Single missed pills should be taken as soon as remembered. 2.2 How to Start Drospirenone and Ethinyl Estradiol Tablets Instruct the patient to begin taking drospirenone and ethinyl estradiol tablets either on the first day of her menstrual period (Day 1 Start) or on the first Sunday after the onset of her menstrual period (Sunday Start). Day 1 Start During the first cycle of drospirenone and ethinyl estradiol tablets use, instruct the patient to take one brown to reddish brown drospirenone and ethinyl estradiol tablet daily, beginning on Day 1 of her menstrual cycle. (The first day of menstruation is Day 1.) She should take one brown to reddish brown drospirenone and ethinyl estradiol tablet daily for 24 consecutive days, followed by one white to off-white inert tablet daily on Days 25 through 28. Drospirenone and ethinyl estradiol tablets should be taken in the order directed on the package at the same time each day, preferably after the evening meal or at bedtime with some liquid, as needed. Drospirenone and ethinyl estradiol tablets can be taken without regard to meals. If drospirenone and ethinyl estradiol tablets are first taken later than the first day of the menstrual cycle, drospirenone and ethinyl estradiol tablets should not be considered effective as a contraceptive until after the first 7 consecutive days of product administration. Instruct the patient to use a non-hormonal contraceptive as back-up during the first 7 days. The possibility of ovulation and conception prior to initiation of medication should be considered. Sunday Start During the first cycle of drospirenone and ethinyl estradiol tablet use, instruct the patient to take one brown to reddish brown drospirenone and ethinyl estradiol tablet daily, beginning on the first Sunday after the onset of her menstrual period. She should take one brown to reddish brown drospirenone and ethinyl estradiol tablet daily for 24 consecutive days, followed by one white to off-white inert tablet daily on Days 25 through 28. Drospirenone and ethinyl estradiol tablets should be taken in the order directed on the package at the same time each day, preferably after the evening meal or at bedtime with some liquid, as needed. Drospirenone and ethinyl estradiol tablets can be taken without regard to meals. Drospirenone and ethinyl estradiol tablets should not be considered effective as a contraceptive until after the first 7 consecutive days of product administration. Instruct the patient to use a non-hormonal contraceptive as back-up during the first 7 days. The possibility of ovulation and conception prior to initiation of medication should be considered. The patient should begin her next and all subsequent 28-day regimens of drospirenone and ethinyl estradiol tablets on the same day of the week that she began her first regimen, following the same schedule. She should begin taking her brown to reddish brown tablets on the next day after ingestion of the last white to off-white tablet, regardless of whether or not a menstrual period has occurred or is still in progress. Anytime a subsequent cycle of drospirenone and ethinyl estradiol tablets is started later than the day following administration of the last white to off-white tablet, the patient should use another method of contraception until she has taken a brown to reddish brown drospirenone and ethinyl estradiol tablet daily for seven consecutive days.

5 WARNINGS AND PRECAUTIONS • Vascular risks : Stop drospirenone and ethinyl estradiol tablets if a thrombotic event occurs. Stop at least 4 weeks before and through 2 weeks after major surgery. Start no earlier than 4 weeks after delivery, in women who are not breastfeeding. ( 5.1 ) COCs containing DRSP may be associated with a higher risk of venous thromboembolism (VTE) than COCs containing levonorgestrel or some other progestins. Before initiating drospirenone and ethinyl estradiol tablets in a new COC user or a woman who is switching from a contraceptive that does not contain DRSP, consider the risks and benefits of a DRSP-containing COC in light of her risk of a VTE. ( 5.1 ) • Hyperkalemia : DRSP has anti-mineralocorticoid activity. Do not use in patients predisposed to hyperkalemia. Check serum potassium concentration during the first treatment cycle in women on long-term treatment with medications that may increase serum potassium concentration. ( 5.2 , 7.1 , 7.2 ) • Liver disease : Discontinue drospirenone and ethinyl estradiol tablets if jaundice occurs. ( 5.4 ) • High blood pressure : Do not prescribe drospirenone and ethinyl estradiol tablets for women with uncontrolled hypertension or hypertension with vascular disease. ( 5.6 ) • Carbohydrate and lipid metabolic effects : Monitor prediabetic and diabetic women taking drospirenone and ethinyl estradiol tablets. Consider an alternate contraceptive method for women with uncontrolled dyslipidemia. ( 5.8 ) • Headache : Evaluate significant change in headaches and discontinue drospirenone and ethinyl estradiol tablets if indicated. ( 5.9 ) • Uterine bleeding : Evaluate irregular bleeding or amenorrhea. ( 5.10 ) 5.1 Thromboembolic Disorders and Other Vascular Problems Stop drospirenone and ethinyl estradiol tablets if an arterial or venous thrombotic (VTE) event occurs. Based on presently available information on DRSP-containing COCs with 0.03 mg ethinyl estradiol (that is, Yasmin), DRSP-containing COCs may be associated with a higher risk of venous thromboembolism (VTE) than COCs containing the progestin levonorgestrel or some other progestins. Epidemiologic studies that compared the risk of VTE reported that the risk ranged from no increase to a three-fold increase. Before initiating use of drospirenone and ethinyl estradiol tablets in a new COC user or a woman who is switching from a contraceptive that does not contain DRSP, consider the risks and benefits of a DRSP-containing COC in light of her risk of a VTE. Known risk factors for VTE include smoking, obesity, and family history of VTE, in addition to other factors that contraindicate use of COCs [see Contraindications ( 4 )] . A number of studies have compared the risk of VTE for users of Yasmin (which contains 0.03 mg of EE and 3 mg of DRSP) to the risk for users of other COCs, including COCs containing levonorgestrel. Those that were required or sponsored by regulatory agencies are summarized in Table 2.

4 CONTRAINDICATIONS Drospirenone and ethinyl estradiol tablets are contraindicated in females who are known to have or develop the following conditions: • Renal impairment • Adrenal insufficiency • A high risk of arterial or venous thrombotic diseases. Examples include women who are known to: o Smoke, if over age 35 [see Boxed Warning and Warnings and Precautions ( 5.1 )] o Have deep vein thrombosis or pulmonary embolism, now or in the past [see Warnings and Precautions ( 5.1 )] o Have cerebrovascular disease [see Warnings and Precautions ( 5.1 )] o Have coronary artery disease [see Warnings and Precautions ( 5.1 )] o Have thrombogenic valvular or thrombogenic rhythm diseases of the heart (for example, subacute bacterial endocarditis with valvular disease, or atrial fibrillation) [see Warnings and Precautions ( 5.1 )] o Have inherited or acquired hypercoagulopathies [see Warnings and Precautions ( 5.1 )] o Have uncontrolled hypertension [see Warnings and Precautions ( 5.6 )] o Have diabetes mellitus with vascular disease [see Warnings and Precautions ( 5.8 )] o Have headaches with focal neurological symptoms or have migraine headaches with or without aura if over age 35 [see Warnings and Precautions ( 5.9 )] • Undiagnosed abnormal uterine bleeding [see Warnings and Precautions ( 5.10 )] • Current diagnosis of, or history of, breast cancer, which may be hormone-sensitive [see Warnings and Precautions ( 5.3 )] • Liver tumors, benign or malignant, or liver disease [see Warnings and Precautions ( 5.4 ) and Use in Specific Populations ( 8.7 )] • Use of Hepatitis C drug combinations containing ombitasvir, paritaprevir/ritonavir, with or without dasabuvir due to the potential for ALT elevations [see Warnings and Precautions ( 5.5 ) and Drug Interactions ( 7.3 )]. • Renal impairment ( 4 ) • Adrenal insufficiency ( 4 ) • A high risk of arterial or venous thrombotic diseases ( 4 ) • Undiagnosed abnormal uterine bleeding ( 4 ) • Breast cancer ( 4 ) • Liver tumors or liver disease ( 4 ) • Co-administration with Hepatitis C drug combinations containing ombitasvir, paritaprevir/ritonavir, with or without dasabuvir ( 4 )

7 DRUG INTERACTIONS Consult the labeling of all concurrently-used drugs to obtain further information about interactions with hormonal contraceptives or the potential for enzyme alterations. Drugs or herbal products that induce certain enzymes (for example, CYP3A4) may decrease the effectiveness of COCs or increase breakthrough bleeding. Counsel patients to use a back-up or alternative method of contraception when enzyme inducers are used with COCs. ( 7.1 ) 7.1 Effects of Other Drugs on Combined Oral Contraceptives Substances diminishing the efficacy of COCs: Drugs or herbal products that induce certain enzymes, including cytochrome P450 3A4 (CYP3A4), may decrease the effectiveness of COCs or increase breakthrough bleeding. Some drugs or herbal products that may decrease the effectiveness of hormonal contraceptives include phenytoin, barbiturates, carbamazepine, bosentan, felbamate, griseofulvin, oxcarbazepine, rifampin, topiramate and products containing St. John’s wort. Interactions between oral contraceptives and other drugs may lead to breakthrough bleeding and/or contraceptive failure. Counsel women to use an alternative method of contraception or a back-up method when enzyme inducers are used with COCs, and to continue back-up contraception for 28 days after discontinuing the enzyme inducer to ensure contraceptive reliability. Substances increasing the plasma concentrations of COCs: Co-administration of atorvastatin and certain COCs containing EE increase AUC values for EE by approximately 20%. Ascorbic acid and acetaminophen may increase plasma EE concentrations, possibly by inhibition of conjugation. Concomitant administration of moderate or strong CYP3A4 inhibitors such as azole antifungals (e.g., ketoconazole, itraconazole, voriconazole, fluconazole), verapamil, macrolides (e.g., clarithromycin, erythromycin), diltiazem, and grapefruit juice can increase the plasma concentrations of the estrogen or the progestin or both. In a clinical drug-drug interaction study conducted in premenopausal women, once daily co-administration of DRSP 3 mg/EE 0.02 mg containing tablets with strong CYP3A4 inhibitor, ketoconazole 200 mg twice daily for 10 days resulted in a moderate increase of DRSP systemic exposure. The exposure of EE was increased mildly [see Warnings and Precautions ( 5.2 ) and Clinical Pharmacology ( 12.3 )] . Human immunodeficiency virus (HIV)/ Hepatitis C virus (HCV) protease inhibitors and non-nucleoside reverse transcriptase inhibitors: Significant changes (increase or decrease) in the plasma concentrations of estrogen and progestin have been noted in some cases of co-administration with HIV/HCV protease inhibitors or 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. 7.2 Effects of Combined Oral Contraceptives on Other Drugs COCs containing EE may inhibit the metabolism of other compounds. COCs have been shown to significantly decrease plasma concentrations of lamotrigine, likely due to induction of lamotrigine glucuronidation. This may reduce seizure control; therefore, dosage adjustments of lamotrigine may be necessary. Consult the labeling of the concurrently-used drug to obtain further information about interactions with COCs or the potential for enzyme alterations. COCs Increasing the Plasma Concentrations of CYP450 Enzymes : In clinical studies, administration of a hormonal contraceptive containing EE did not lead to any increase or only to a weak increase in plasma concentrations of CYP3A4 substrates (e.g., midazolam) while plasma concentrations of CYP2C19 substrates (e.g., omeprazole and voriconazole) and CYP1A2 substrates (e.g., theophylline and tizanidine) can have a weak or moderate increase. Clinical studies did not indicate an inhibitory potential of DRSP toward…

8.1 Pregnancy Risk Summary There is no use for contraception in pregnancy; therefore, drospirenone and ethinyl estradiol tablets 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 CHCs before conception or during early pregnancy. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4 percent and 15 to 20 percent, respectively. Data Human Data A retrospective database study of women in Norway, that included 44,734 pregnancies of which 368 were women who inadvertently took DRSP/EE during the first trimester of a pregnancy, found there were no adverse effects on pre-term birth, small for gestational age, or birth weight Z-scores. Post-marketing adverse event data on the use of drospirenone and ethinyl estradiol tablets in pregnant women suggest that frequencies of miscarriage and congenital anomalies were not higher than the estimated background risk in the general population.

6 ADVERSE REACTIONS The following serious adverse reactions with the use of COCs are discussed elsewhere in the labeling: • Serious cardiovascular events and stroke [see Boxed Warning and Warnings and Precautions ( 5.1 )] • Vascular events [see Warnings and Precautions ( 5.1 )] • Liver disease [see Warnings and Precautions ( 5.4 )] • The most frequent adverse reactions (≥ 2%) in contraception and acne clinical trials were: headache/migraine (6.7%), menstrual irregularities (4.7%), nausea/vomiting (4.2%), breast pain/tenderness (4.0%) and mood changes (2.2%). ( 6.1 ) • The most frequent adverse reactions (≥ 2%) in PMDD clinical trials were: menstrual irregularities (24.9%), nausea (15.8%), headache (13.0%), breast tenderness (10.5%), fatigue (4.2%), irritability (2.8%), decreased libido (2.8%), increased weight (2.5%), and affect lability (2.1%). ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Glenmark Pharmaceuticals Inc., USA at 1 (888) 721-7115 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.1 Clinical Trials Experience 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. Contraception and Acne Clinical Trials The data provided reflect the experience with the use of drospirenone and ethinyl estradiol tablets in the adequate and well-controlled studies for contraception (N=1,056) and for moderate acne vulgaris (N=536). For contraception, a Phase 3, multicenter, multinational, open-label study was conducted to evaluate safety and efficacy up to one year in 1,027 women aged 17 to 36 who took at least one dose of drospirenone and ethinyl estradiol tablets. A second Phase 3 study was a single center, open-label, active-controlled study to evaluate the effect of 7 28-day cycles of drospirenone and ethinyl estradiol tablets on carbohydrate metabolism, lipids and hemostasis in 29 women aged 18 to 35. For acne, two multicenter, double-blind, randomized, placebo-controlled studies, in 536 women aged 14 to 45 with moderate acne vulgaris who took at least one dose of drospirenone and ethinyl estradiol tablets, evaluated the safety and efficacy during up to 6 cycles. The adverse reactions seen across the 2 indications overlapped, and are reported using the frequencies from the pooled dataset. The most common adverse reactions (≥ 2% of users) were: headache/migraine (6.7%), menstrual irregularities (including vaginal hemorrhage [primarily spotting] and metrorrhagia (4.7%), nausea/vomiting (4.2%), breast pain/tenderness (4%) and mood changes (mood swings, depression, depressed mood and affect lability) (2.2%). PMDD Clinical Trials Safety data from trials for the indication of PMDD are reported separately due to differences in study design and setting in the Contraception and Acne studies as compared to the PMDD clinical program. Two (one parallel and one crossover designed) multicenter, double-blind, randomized, placebo-controlled trials for the secondary indication of treating the symptoms of PMDD evaluated safety and efficacy of drospirenone and ethinyl estradiol tablets during up to 3 cycles among 285 women aged 18–42, diagnosed with PMDD and who took at least one dose of drospirenone and ethinyl estradiol tablets. Common adverse reactions (≥ 2% of users) were: menstrual irregularities (including vaginal hemorrhage [primarily spotting] and metrorrhagia) (24.9%), nausea (15.8%), headache (13.0%), breast tenderness (10.5%), fatigue (4.2%), irritability (2.8%), decreased libido (2.8%), increased weight (2.5%), and affect lability (2.1%). Adverse Reactions (≥1%) Leading to Study Discontinuation: Contraception Clinical Trials Of 1,056 women, 6.6% discontinued from the clinical trials due to an adverse reaction; the most frequent adverse reactions leading to discontinuation were headache/migraine (1.6%) and nausea/vomiting (1…
