Vestura is 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 Vestura ® (drospirenone and ethinyl estradiol) tablets are indicated for use by females of reproductive potential to prevent pregnancy. 1.2 Premenstrual Dysphoric Disorder (PMDD) Vestura is 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 Vestura 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. Vestura has not been evaluated for the treatment of premenstrual syndrome (PMS). 1.3 Acne Vestura is 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. Vestura should be used for the treatment of acne only if the patient desires an oral contraceptive for birth control.

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 Vestura 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, Vestura 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 Vestura Instruct the patient to begin taking Vestura 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 Vestura use, instruct the patient to take one pink Vestura daily, beginning on Day 1 of her menstrual cycle. (The first day of menstruation is Day 1.) She should take one pink Vestura daily for 24 consecutive days, followed by one white inert tablet daily on Days 25 through 28. Vestura 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. Vestura can be taken without regard to meals. If Vestura is first taken later than the first day of the menstrual cycle, Vestura 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 Vestura use, instruct the patient to take one pink Vestura daily, beginning on the first Sunday after the onset of her menstrual period. She should take one pink Vestura daily for 24 consecutive days, followed by one white inert tablet daily on Days 25 through 28. Vestura 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. Vestura can be taken without regard to meals. Vestura 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 Vestura on the same day of the week that she began her first regimen, following the same schedule. She should begin taking her pink tablets on the next day after ingestion of the last white tablet, regardless of whether or not a menstrual period has occurred or is still in progress. Anytime a subsequent cycle of Vestura is started later than the day following administration of the last white tablet, the patient should use another method of contraception until she has taken a pink Vestura daily for seven consecutive days. When switching from a different birth control pill When switching from another birth control pill, Vestura should be started on the same day that a new pack of the previous oral contraceptive would have been started. When switching from a method other than a birth control pill When switching from a transdermal patch or vaginal ring, Vestura should be started when the next application would have been due. When switching from an injection, Vestura should be started when the next dose would have been due. When switching from an intrauterine contraceptive or an implant, Vestura should be started on the day of removal. Withdrawal bleeding usually occurs within 3 days following the last pink tablet. If spotting or breakthrough bleeding occurs while taking Vestura, instruct the patient to continue taking Vestura by the regimen described above. Counsel her that this type of bleeding is usually transient and without significance; however, advise her that if the bleeding is persistent or prolonged, she should consult her healthcare provider. Although the occurrence of pregnancy is low if Vestura is taken according to directions, if withdrawal bleeding does not occur, consider the possibility of pregnancy. If the patient has not adhered to the prescribed dosing schedule (missed one or more active tablets or started taking them on a day later than she should have), consider the possibility of pregnancy at the time of the first missed period and take appropriate diagnostic measures. If the patient has adhered to the prescribed regimen and misses two consecutive periods, rule out pregnancy. Discontinue Vestura if pregnancy is confirmed. The risk of pregnancy increases with each active pink tablet missed. If breakthrough bleeding occurs following missed tablets, it will usually be transient and of no consequence. If the patient misses one or more white tablets, she should still be protected against pregnancy provided she begins taking a new cycle of pink tablets on the proper day. For postpartum women who do not breastfeed or after a second trimester abortion, start Vestura no earlier than 4 weeks postpartum due to the increased risk of thromboembolism. If the patient starts on Vestura postpartum and has not yet had a period, evaluate for possible pregnancy, and instruct her to use an additional method of contraception until she has taken Vestura for 7 consecutive days. 2.3 Missed Doses Table 1: Instructions for Vestura Missed Doses If one pink active tablet is missed Take the missed active tablet as soon as possible. Take the next tablet at the regular time. This means two tablets may be taken in one day. A back-up birth control method is not required if the patient has sex. If two pink active tablets in a row are missed in Week 1 or Week 2 Take two active tablets as soon as possible and two tablets the next day. Then take one tablet a day until the pack is finished. Additional nonhormonal contraception (such as condoms and spermicide) should be used as back-up if the patient has sex within 7 days after missing tablets. If two pink active tablets in a row are missed in Week 3 or Week 4 Day 1 Start: Throw out the rest of the tablet pack and start a new pack that same day. Sunday Start: Keep taking one tablet every day until Sunday. On Sunday, throw out the rest of the pack and start a new pack of tablets that same day. Additional nonhormonal contraception (such as condoms and spermicide) should be used as back-up if the patient has sex within 7 days after missing tablets. The patient may not have their period this month but this is expected. However, if they miss their period two months in a row, they should call their healthcare provider because they might be pregnant. If three or more pink active tablets in a row are missed during any week Day 1 Start: Throw out the rest of the tablet pack and start a new pack that same day. Sunday Start: Keep taking one tablet every day until Sunday. On Sunday, throw out the rest of the pack and start a new pack of tablets that same day. The patient could become pregnant if they have sex in the 7 days after they restart their tablets. They must use another birth control method (such as condoms and spermicides) as a back-up for those 7 days. They should call their healthcare provider if they miss their period, because they might be pregnant. If any of the four white inactive tablets are missed in Week 4 Throw away the tablets that were missed. Keep taking one tablet each day until the pack is empty. They do not need a back-up method. Finally, if they are still not sure what to do about the tablets they have missed: Use nonhormonal contraception (such as condoms and spermicides) anytime they have sex. Contact their healthcare provider and continue taking one active pink tablet each day until otherwise directed. 2.4 Advice in Case of Gastrointestinal Disturbances In case of severe vomiting or diarrhea, absorption may not be complete and additional contraceptive measures should be taken. If vomiting occurs within 3 to 4 hours after tablet-taking, this can be regarded as a missed tablet.

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 to 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 (1.0%). Acne Clinical Trials Of 536 women, 5.4% discontinued from the clinical trials due to an adverse reaction; the most frequent adverse reaction leading to discontinuation was menstrual irregularities (including menometrorrhagia, menorrhagia, metrorrhagia and vaginal hemorrhage) (2.2%). PMDD Clinical Trials Of 285 women, 11.6% discontinued from the clinical trials due to an adverse reaction; the most frequent adverse reactions leading to discontinuation were: nausea/vomiting (4.6%), menstrual irregularity (including vaginal hemorrhage, menorrhagia, menstrual disorder, menstruation irregular and metrorrhagia) (4.2%), fatigue (1.8%), breast tenderness (1.4%), depression (1.4%), headache (1.1%), and irritability (1.1%). Serious Adverse Reactions Contraception Clinical Trials : migraine and cervical dysplasia Acne Clinical Trials: none reported in the clinical trials PMDD Clinical Trials: cervical dysplasia 6.2 Postmarketing Experience Five studies that compared breast cancer risk between ever-users (current or past use) of COCs and never-users of COCs reported no association between ever use of COCs and breast cancer risk, with effect estimates ranging from 0.90 to 1.12 (Figure 3). Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 3). One of these studies reported no association between breast cancer risk and COC use. The other two studies found an increased relative risk of 1.19 to 1.33 with current or recent use. Both of these studies found an increased risk of breast cancer with current use of longer duration, with relative risks ranging from 1.03 with less than one year of COC use to approximately 1.4 with more than 8 to 10 years of COC use. Figure 3: Relative Studies of Risk of Breast Cancer with Combined Oral Contraceptives RR = relative risk; OR = odds ratio; HR = hazard ratio. “ever COC” are females with current or past COC use; “never COC use” are females that never used COCs. The following adverse reactions have been identified during post approval use of Vestura. 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. Adverse reactions are grouped into System Organ Classes, and ordered by frequency. Vascular disorders: Venous and arterial thromboembolic events (including pulmonary emboli, deep vein thrombosis, cerebral thrombosis, retinal thrombosis, myocardial infarction and stroke), hypertension (including hypertensive crisis) Hepatobiliary disorders: Gallbladder disease, liver function disturbances, liver tumors Immune system disorders: Hypersensitivity (including anaphylactic reaction) Metabolism and nutrition disorders: Hyperkalemia, hypertriglyceridemia, changes in glucose tolerance or effect on peripheral insulin resistance (including diabetes mellitus) Skin and subcutaneous tissue disorders: Chloasma, angioedema, erythema nodosum, erythema multiforme Gastrointestinal disorders: Inflammatory bowel disease Musculoskeletal and connective tissue disorders: Systemic lupus erythematosus 3

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: Coadministration 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 coadministration 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 coadministration 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 towards human CYP enzymes at clinically relevant concentrations [see Clinical Pharmacology ( 12.3 ) ] . Women on thyroid hormone replacement therapy may need increased doses of thyroid hormone because serum concentration of thyroid-binding globulin increases with use of COCs. Potential to Increase Serum Potassium Concentration : There is a potential for an increase in serum potassium concentration in women taking Vestura with other drugs that may increase serum potassium concentration [see Warnings and Precautions ( 5.2 ) and Clinical Pharmacology ( 12.3 )] . 7.3 Concomitant Use with HCV Combination Therapy – Liver Enzyme Elevation Do not coadminister Vestura with HCV drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, due to potential for ALT elevations [see Warnings and Precautions ( 5.5 )] . 7.4 Interference with Laboratory Tests The use of contraceptive steroids may influence the results of certain laboratory tests, such as coagulation factors, lipids, glucose tolerance, and binding proteins. DRSP causes an increase in plasma renin activity and plasma aldosterone induced by its mild anti-mineralocorticoid activity [see Warnings and Precautions ( 5.12 ) and Drug Interactions ( 7.2 )].
