• 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 ) • Do not skip or delay intake by more than 12 hours. ( 2.1 ) 2.1 How to Take Estradiol Valerate and Estradiol Valerate/Dienogest To achieve maximum contraceptive effectiveness, Estradiol Valerate and Estradiol Valerate/Dienogest must be taken exactly as directed. Take one tablet by mouth at the same time every day. Tablets must be taken in the order directed on the blister pack. Tablets should not be skipped or intake delayed by more than 12 hours. For patient instructions for missed pills, see FDA-Approved Patient Labeling. 2.2 How to Start Estradiol Valerate and Estradiol Valerate/Dienogest Instruct the patient to begin taking Estradiol Valerate and Estradiol Valerate/Dienogest on Day 1 of her menstrual cycle (that is, the first day of her menstrual bleeding). See FDA-Approved Patient Labeling . Instruct the patient to use a non-hormonal contraceptive as back-up during the first 9 days. For postpartum women who do not breastfeed or after a second trimester abortion, start Estradiol Valerate and Estradiol Valerate/Dienogest no earlier than 4 weeks postpartum due to the increased risk of thromboembolism. If the patient starts on Estradiol Valerate and Estradiol Valerate/Dienogest 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 Estradiol Valerate and Estradiol Valerate/Dienogest for 9 consecutive days. The possibility of ovulation and conception prior to initiation of medication should also be considered. If the patient is switching from a combination hormonal method such as a: • Another pill • Vaginal ring • Patch • Instruct her to take the first dark yellow pill on the first day of her withdrawal bleed. She should not continue taking the pills from her previous birth control pack. If she does not have a withdrawal bleed, rule out pregnancy before starting Estradiol Valerate and Estradiol Valerate/Dienogest. • If she previously used a vaginal ring or transdermal patch, she should start using Estradiol Valerate and Estradiol Valerate/Dienogest on the day the ring or patch is removed. • Instruct the patient to use a non-hormonal back-up method such as a condom or spermicide for the first 9 days. If the patient is switching from a progestin-only method such as a: • Progestin-only pill • Implant • Intrauterine system • Injection • Instruct her to take the first dark yellow pill on the day she would have taken her next progestin-only pill or on the day of removal of her implant or intrauterine system or on the day when she would have had her next injection. • Instruct the patient to use a non-hormonal back-up method such as a condom or spermicide for the first 9 days. 2.3 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 or diarrhea occurs within 3-4 hours after taking a colored tablet, this can be regarded as a missed tablet.

Contraception and Heavy Menstrual Bleeding Studies A total of 2,131 women, 18 to 54 years of age, who took at least one dose of Estradiol Valerate and Estradiol Valerate/Dienogest were enrolled in four clinical phase 3 trials. A total of 1,867 subjects were included in two clinical phase 3 studies with a treatment duration up to 28 cycles with Estradiol Valerate and Estradiol Valerate/Dienogest as an oral contraceptive and 264 subjects in the two phase 3 clinical trials with a treatment duration of 7 cycles evaluating Estradiol Valerate and Estradiol Valerate/Dienogest in the treatment of heavy, prolonged, and/or frequent menstrual bleeding in women without organic pathology. [See Clinical Studies ( 14.1 , 14.2 .)] Adverse Reactions Leading to Study Discontinuation : 11.4% of the women discontinued from the clinical trials due to an adverse reaction; the most frequent adverse reactions leading to discontinuation were menstrual disorder (metrorrhagia, menorrhagia, menstruation irregular, genital hemorrhage, vaginal hemorrhage, dysfunctional uterine bleeding) (2.3%); mood changes (depression, mood swings, mood altered, depressed mood, dysthymic disorder, crying) (1.2%); acne (1.1%), headache (including migraines) (1.1%), and weight increased (0.7 %). Common Adverse Reactions (≥ 2%): headache (including migraines) (12.7%), breast pain, discomfort or tenderness (7.0%), menstrual disorders (metrorrhagia, menstruation irregular, menorrhagia, vaginal hemorrhage, dysfunctional uterine bleeding, genital hemorrhage, abnormal withdrawal bleeding, uterine hemorrhage) (6.9%), nausea or vomiting (6.0%), acne (3.9%), mood changes (depression, mood swings, depressed mood, mood altered, affect lability, dysthymic disorder, crying) (3.0%) and increased weight (2.9%). Serious Adverse Reactions: myocardial infarction (2 cases), ruptured ovarian cyst (2 cases), deep vein thrombosis, focal nodular hyperplasia of the liver, uterine leiomyoma, acute cholecystitis, and chronic acalculous cholecystitis. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of Estradiol Valerate and Estradiol Valerate/Dienogest. 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. Vascular disorders: Venous and arterial thromboembolic events (including pulmonary emboli, deep vein thrombosis, cerebral thrombosis, myocardial infarction and stroke), hypertension Hepatobiliary disorders: Gallbladder disease, hepatitis Immune system disorders: Hypersensitivity Metabolism and nutrition disorders: Fluid retention, hypertriglyceridemia Nervous system disorders: Dizziness Skin and subcutaneous tissue disorders: Chloasma, angioedema, erythema nodosum, erythema multiforme Gastrointestinal disorders: Gastrointestinal symptoms (for example, abdominal pain) Infections and infestations: Vulvovaginal candidiasis

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 Interactions between oral contraceptives and other drugs may lead to breakthrough bleeding and/or contraceptive failure. The following interactions have been reported in the literature for COCs in general or were studied in clinical trials with Estradiol Valerate and Estradiol Valerate/Dienogest. CYP3A4 Inducers : Drugs or herbal products that induce certain enzymes, including 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 barbiturates, bosentan, felbamate, griseofulvin, oxcarbazepine, and topiramate. Counsel women to use an alternative method of contraception or a back-up method when moderate or weak enzyme inducers are used with COCs, and to continue back-up contraception for 28 days after discontinuing the enzyme inducer to ensure contraceptive reliability. Dienogest is a substrate of CYP3A4. Women who take medications that are strong CYP3A4 inducers (for example, carbamazepine, phenytoin, rifampicin, and St. John’s wort) should not choose Estradiol Valerate and Estradiol Valerate/Dienogest as their oral contraceptive while using these inducers and for at least 28 days after discontinuation of these inducers due to the possibility of decreased contraceptive efficacy. The effect of the CYP3A4 inducer rifampicin was studied in healthy postmenopausal women. Co-administration of rifampicin with estradiol valerate/dienogest tablets led to a 52 % and 83% decrease in the mean C max and AUC (0–24hr), respectively, for dienogest and a 25% and 44% decrease in C max and AUC (0–24hr), respectively, for estradiol at steady state. Strong CYP3A4 Inhibitors : Strong CYP3A4 inhibitors such as ketoconazole increased hormone serum concentrations. In a study investigating the effect of ketoconazole on dienogest and estradiol pharmacokinetics, co-administration with the strong CYP3A4 inhibitor ketoconazole resulted in a 186% increase of AUC (0–24hr) at steady state for dienogest and a 57% increase for estradiol. There was also a 94% and 65% increase of C max at steady state for dienogest and estradiol when co-administered with ketoconazole. Moderate CYP3A4 Inhibitors : The AUC (0–24hr) of dienogest and estradiol at steady state were increased by 62% and 33%, respectively, when co-administered with a moderate CYP3A4 inhibitor, erythromycin. There was also a 33% and 51% increase of Cmax at steady state for dienogest and estradiol, respectively, when co-administered with erythromycin. Other known CYP3A4 inhibitors like azole antifungals, cimetidine, verapamil, macrolides, diltiazem, antidepressants, and grapefruit juice may increase plasma concentrations of dienogest. Human Immunodeficiency Virus (HIV)/Hepatitis C Virus (HCV) Protease Inhibitors and Non-Nucleoside Reverse Transcriptase Inhibitors : Significant changes (increase and decrease) in plasma concentrations of estrogen and progestin have been noted in some cases of co-administration of 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 ethinyl estradiol 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. In vitro studies with human CYP enzymes did not indicate an inhibitory potential of dienogest at clinically relevant concentrations. Women on thyroid hormone replacement therapy may need increased doses of thyroid hormone because serum concentrations of thyroid-binding globulin increase with use of COCs. 7.3 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 [see Warnings and Precautions ( 5.11 ) and Drug Interactions ( 7.2 )].
