VIORELE

DOSAGE AND ADMINISTRATION To achieve maximum contraceptive effectiveness, VIORELE ® (desogestrel and ethinyl estradiol tablets, USP and ethinyl estradiol tablets, USP) must be taken exactly as directed and at intervals not exceeding 24 hours. VIORELE ® may be initiated using either a Sunday start or a Day 1 start. NOTE: Each cycle pack blister is preprinted with the days of the week, starting with Sunday, to facilitate a Sunday start regimen. Six different “day label strips” are provided with each cycle pack blister in order to accommodate a Day 1 start regimen. In this case, the patient should place the self-adhesive “day label strip” that corresponds to her starting day over the preprinted days. IMPORTANT: The possibility of ovulation and conception prior to initiation of use of VIORELE ® should be considered. The use of VIORELE ® for contraception may be initiated 4 weeks postpartum in women who elect not to breast-feed. When the tablets are administered during the postpartum period, the increased risk of thromboembolic disease associated with the postpartum period must be considered (see CONTRAINDICATIONS and WARNINGS concerning thromboembolic disease. See also PRECAUTIONS for Nursing mothers). If the patient starts on VIORELE ® postpartum, and has not yet had a period, she should be instructed to use another method of contraception until a white to off-white tablet has been taken daily for 7 days. SUNDAY START When initiating a Sunday start regimen, another method of contraception should be used until after the first 7 consecutive days of administration. Using a Sunday start, tablets are taken daily without interruption as follows: The first white to off-white tablet should be taken on the first Sunday after menstruation begins (if menstruation begins on Sunday, the first white to off-white tablet is taken on that day). One white to off-white tablet is taken daily for 21 days, followed by 1 pale green to yellowish green (inert) tablet daily for 2 days and 1 light yellow to yellow (active) tablet daily for 5 days. For all subsequent cycles, the patient then begins a new 28-tablet regimen on the next day (Sunday) after taking the last light yellow to yellow tablet. [If switching from a Sunday start oral contraceptive, the first VIORELE ® tablet should be taken on the second Sunday after the last tablet of a 21-day regimen or should be taken on the first Sunday after the last inactive tablet of a 28 day regimen.] If a patient misses 1 white to off-white tablet, she should take the missed tablet as soon as she remembers. If the patient misses 2 consecutive white to off-white tablets in Week 1 or Week 2, the patient should take 2 tablets the day she remembers and 2 tablets the next day; thereafter, the patient should resume taking 1 tablet daily until she finishes the cycle pack. The patient should be instructed to use a back-up method of birth control if she has intercourse in the 7 days after missing pills. If the patient misses 2 consecutive white to off-white tablets in the third week or misses 3 or more white to off-white tablets in a row at any time during the cycle, the patient should keep taking 1 white to off-white tablet daily until the next Sunday. On Sunday the patient should throw out the rest of that cycle pack and start a new cycle pack that same day. The patient should be instructed to use a back-up method of birth control if she has intercourse in the 7 days after missing pills. DAY 1 START Counting the first day of menstruation as “Day 1”, tablets are taken without interruption as follows: One white to off-white tablet daily for 21 days, one pale green to yellowish green (inert) tablet daily for 2 days followed by 1 light yellow to yellow (ethinyl estradiol) tablet daily for 5 days. For all subsequent cycles, the patient then begins a new 28-tablet regimen on the next day after taking the last light yellow to yellow tablet. [If switching directly from another oral contraceptive, the first white to off-white t …

CONTRAINDICATIONS Oral contraceptives should not be used in women who currently have the following conditions: • Thrombophlebitis or thromboembolic disorders • A past history of deep vein thrombophlebitis or thromboembolic disorders • Cerebral vascular or coronary artery disease • Current diagnosis of, or history of, breast cancer, which may be hormone-sensitive • Undiagnosed abnormal genital bleeding • Cholestatic jaundice of pregnancy or jaundice with prior pill use • Hepatic adenomas or carcinomas • Are receiving Hepatitis C drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, due to the potential for ALT elevations (see WARNINGS, RISK OF LIVER ENZYME ELEVATIONS WITH CONCOMITANT HEPATITIS C TREATMENT ).

ADVERSE REACTIONS An increased risk of the following serious adverse reactions has been associated with the use of oral contraceptives (see WARNINGS section): • Thrombophlebitis and venous thrombosis with or without embolism • Arterial thromboembolism • Pulmonary embolism • Myocardial infarction • Cerebral hemorrhage • Cerebral thrombosis • Hypertension • Gallbladder disease • Hepatic adenomas or benign liver tumors Post Marketing 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 2). (64 to 68). Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 2). (64, 67, 69) 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 2: RELEVANT 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. There is evidence of an association between the following conditions and the use of oral contraceptives: • Mesenteric thrombosis • Retinal thrombosis The following adverse reactions have been reported in patients receiving oral contraceptives and are believed to be drug-related: • Nausea • Vomiting • Gastrointestinal symptoms (such as abdominal cramps and bloating) • Breakthrough bleeding • Spotting • Change in menstrual flow • Amenorrhea • Temporary infertility after discontinuation of treatment • Edema • Melasma which may persist • Breast changes: tenderness, enlargement, secretion • Change in weight (increase or decrease) • Change in cervical erosion and secretion • Diminution in lactation when given immediately postpartum • Cholestatic jaundice • Migraine • Rash (allergic) • Mental depression • Reduced tolerance to carbohydrates • Vaginal candidiasis • Change in corneal curvature (steepening) • Intolerance to contact lenses The following adverse reactions have been reported in users of oral contraceptives and the association has been neither confirmed nor refuted: • Pre-menstrual syndrome • Cataracts • Changes in appetite • Cystitis-like syndrome • Headache • Nervousness • Dizziness • Hirsutism • Loss of scalp hair • Erythema multiforme • Erythema nodosum • Hemorrhagic eruption • Vaginitis • Porphyria • Impaired renal function • Hemolytic uremic syndrome • Acne • Changes in libido • Colitis • Budd-Chiari Syndrome figure2

7. Drug interactions Reduced efficacy and increased incidence of breakthrough bleeding and menstrual irregularities have been associated with concomitant use of rifampin. A similar association, though less marked, has been suggested with barbiturates, phenylbutazone, phenytoin sodium, carbamazepine and possibly with griseofulvin, ampicillin, and tetracyclines (72). Combined hormonal contraceptives have been shown to significantly decrease plasma concentrations of lamotrigine when co-administered, likely due to induction of lamotrigine glucuronidation. This may reduce seizure control; therefore, dosage adjustments of lamotrigine may be necessary. Concomitant Use with Hepatitis C Virus (HCV) Combination Therapy - Liver Enzyme Elevation Co-administration of VIORELE ® with HCV drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir is contraindicated, due to potential for ALT elevations (see CONTRAINDICATION S, WARNINGS, RISK OF LIVER ENZYME ELEVATIONS WITH CONCOMITANT HEPATITIS C TREATMENT). Co-administration of VIORELE ® and glecaprevir/pibrentasvir is not recommended due to potential for ALT elevations. Consult the labeling of the concurrently-used drug to obtain further information about interactions with hormonal contraceptives or the potential for enzyme alterations.
