Drospirenone

1 INDICATIONS AND USAGE Yaz 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 Yaz ® is indicated for use by females of reproductive potential to prevent pregnancy. 1.2 Premenstrual Dysphoric Disorder (PMDD) Yaz 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 Yaz 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. Yaz has not been evaluated for the treatment of premenstrual syndrome (PMS). 1.3 Acne Yaz 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. Yaz should be used for the treatment of acne only if the patient desires an oral contraceptive for birth control.

12.1 Mechanism of Action COCs lower the risk of becoming pregnant primarily by suppressing ovulation.

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 Yaz 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, Yaz 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 Yaz Instruct the patient to begin taking Yaz 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 Yaz use, instruct the patient to take one light pink Yaz daily, beginning on Day 1 of her menstrual cycle. (The first day of menstruation is Day 1.) She should take one light pink Yaz daily for 24 consecutive days, followed by one white inert tablet daily on Days 25 through 28. Yaz 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. Yaz can be taken without regard to meals. If Yaz is first taken later than the first day of the menstrual cycle, Yaz 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 Yaz use, instruct the patient to take one light pink Yaz daily, beginning on the first Sunday after the onset of her menstrual period. She should take one light pink Yaz daily for 24 consecutive days, followed by one white inert tablet daily on Days 25 through 28. Yaz 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. Yaz can be taken without regard to meals. Yaz 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 Yaz on the same day of the week that she began her first regimen, following the same schedule. She should begin taking her light 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 Yaz 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 light pink Yaz daily for seven consecutive days. When switching from a different birth control pill When switching from another birth control pill, Yaz 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, Yaz should be started when the next application would have been due. When switching from an injection, Yaz should be started when the next dose would have been due. When switching from an intrauterine contraceptive or an implant, Yaz should be started on the day of removal. Withdrawal bleeding usually occurs within 3 days following the last light pink tablet. If spotting or breakthrough bleeding occurs while taking Yaz, instruct the patient to continue taking Yaz by the regimen described above. Counsel her that this type of bleeding is usually transient and without significance; however, advise her that if

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%).

Contraception and Acne Clinical Trials The data provided reflect the experience with the use of Yaz 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 – 36 who took at least one dose of Yaz. A second Phase 3 study was a single center, open-label, active-controlled study to evaluate the effect of 7 28-day cycles of Yaz on carbohydrate metabolism, lipids and hemostasis in 29 women aged 18–35. For acne, two multicenter, double-blind, randomized, placebo-controlled studies, in 536 women aged 14–45 with moderate acne vulgaris who took at least one dose of Yaz, 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 Yaz during up to 3 cycles among 285 women aged 18–42, diagnosed with PMDD and who took at least one dose of Yaz. 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, menorrha

5 WARNINGS AND PRECAUTIONS • Vascular risks : Stop Yaz 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 Yaz 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 Yaz if jaundice occurs. ( 5.4 ) • High blood pressure : Do not prescribe Yaz for women with uncontrolled hypertension or hypertension with vascular disease. ( 5.6 ) • Carbohydrate and lipid metabolic effects : Monitor prediabetic and diabetic women taking Yaz. Consider an alternate contraceptive method for women with uncontrolled dyslipidemia. ( 5.8 ) • Headache : Evaluate significant change in headaches and discontinue Yaz if indicated. ( 5.9 ) • Uterine bleeding : Evaluate irregular bleeding or amenorrhea. ( 5.10 ) 5.1 Thromboembolic Disorders and Other Vascular Problems Stop Yaz 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 Yaz 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.
