To achieve maximum contraceptive effectiveness, Enskyce must be taken exactly as directed and at intervals not exceeding 24 hours. Enskyce is available in the blister which is preset for a Sunday Start. Day 1 Start is also provided.

Day 1 Start The dosage of Enskyce for the initial cycle of therapy is one light orange "active" tablet administered daily from the 1 st day through the 21 st day of the menstrual cycle, counting the first day of menstrual flow as "Day 1". Tablets are taken without interruption as follows: One light orange "active" tablet daily for 21 days, then one green "reminder" tablet daily for 7 days. After 28 tablets have been taken, a new course is started and a light orange "active" tablet is taken the next day. The use of Enskyce for contraception may be initiated 4 weeks postpartum in women who elect not to breastfeed.

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, Nursing Mothers). If the patient starts on Enskyce postpartum, and has not yet had a period, she should be instructed to use another method of contraception until a light orange "active" tablet has been taken daily for 7 days. The possibility of ovulation and conception prior to initiation of medication should be considered.

If the patient misses one light orange "active" tablet in Weeks 1, 2, or 3, the light orange "active" tablet should be taken as soon as she remembers. If the patient misses two light orange "active" tablets in Week 1 or Week 2, the patient should take two light orange "active" tablets the day she remembers and two light orange "active" tablets the next day; and then continue taking one light orange "active" tablet a day until she finishes the pack. The patient should be instructed to use a back-up method of birth control such as a condom or spermicide if she has sex in the seven days after missing pills.

If the patient misses two light orange "active" tablets in the third week or misses three or more light orange "active" tablets in a row, the patient should throw out the rest of the pack and start a new pack that same day. The patient should be instructed to use a back-up method of birth control if she has sex in the seven days after missing pills. Sunday Start When taking Enskyce, the first light orange "active" tablet should be taken on the first Sunday after menstruation begins.

If the period begins on Sunday, the first light orange "active" tablet is taken on that day. If switching directly from another oral contraceptive, the first light orange "active" tablet should be taken on the first Sunday after the last ACTIVE tablet of the previous product. Tablets are taken without interruption as follows: One light orange "active" tablet daily for 21 days, then one green "reminder" tablet daily for 7 days.

After 28 tablets have been taken, a new course is started and a light orange "active" tablet is taken the next day (Sunday). When initiating a Sunday start regimen, another method of contraception should be used until after the first 7 consecutive days of administration. The use of Enskyce for contraception may be initiated 4 weeks postpartum. 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.

The patient should be instructed to use a back-up method of birth control if she has sex in the seven days after missing pills. ADDITIONAL INSTRUCTIONS FOR ALL DOSING REGIMENS Breakthrough bleeding, spotting, and amenorrhea are frequent reasons for patients discontinuing oral contraceptives.

In breakthrough bleeding, as in all cases of irregular bleeding from the vagina, nonfunctional causes should be borne in mind. In undiagnosed persistent or recurrent abnormal bleeding from the vagina, adequate diagnostic measures are indicated to rule out pregnancy or malignancy. If pathology has been excluded, time or a change to another formulation may solve the problem.

Changing to an oral contraceptive with a higher estrogen content, while potentially useful in minimizing menstrual irregularity, should be done only if necessary since this may increase the risk of thromboembolic disease. Use of oral contraceptives in the event of a missed menstrual period: If the patient has not adhered to the prescribed schedule, the possibility of pregnancy should be considered at the time of the first missed period and oral contraceptive use should be discontinued if pregnancy is confirmed. If the patient has adhered to the prescribed regimen and misses two consecutive periods, pregnancy should be ruled out.

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 - 1.12 (Figure 2). Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 1). 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 - 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 8-10 years of COC use.

Figure 2: Risk of Breast Cancer with Combined Oral Contraceptive Use 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. An increased risk of the following serious adverse reactions has been associated with the use of oral contraceptives (see WARNINGS ). 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 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 Allergic reaction, including rash, urticaria, and angioedema 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 a causal 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 Figure 2: Risk of Breast Cancer with Combined Oral Contraceptive Use

Serious ill effects have not been reported following acute ingestion of large doses of oral contraceptives by young children. Overdosage may cause nausea, and withdrawal bleeding may occur in females. NON-CONTRACEPTIVE HEALTH BENEFITS The following non-contraceptive health benefits related to the use of oral contraceptives are supported by epidemiological studies which largely utilized oral contraceptive formulations containing estrogen doses exceeding 0.035 mg of ethinyl estradiol or 0.05 mg of mestranol. 73-78 Effects on menses: increased menstrual cycle regularity decreased blood loss and decreased incidence of iron deficiency anemia decreased incidence of dysmenorrhea Effects related to inhibition of ovulation: decreased incidence of functional ovarian cysts decreased incidence of ectopic pregnancies Effects from long-term use: decreased incidence of fibroadenomas and fibrocystic disease of the breast decreased incidence of acute pelvic inflammatory disease decreased incidence of endometrial cancer decreased incidence of ovarian cancer
