Standard Dose

DOSAGE AND ADMINISTRATION 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 (1) 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 (2) light orange "active" tablets in Week 1 or Week 2, the patient should take two (2) light orange "active" tablets the day she remembers and two (2) light orange "active" tablets the next day; and then continue taking one (1) 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 (7) days after missing pills. If the patient misses two (2) light orange "active" tablets in the third week or misses three (3) 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 (7) 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.

On Sunday 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 (7) 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.

Clinical summary

Indications and usage INDICATIONS AND USAGE Enskyce Tablets are indicated for the prevention of pregnancy in women who elect to use oral contraceptives as a method of contraception. Oral contraceptives are highly effective. Table 1 lists the typical accidental pregnancy rates for users of combined oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization, the IUD, and the Norplant System depends upon the reliability with which they are used. Correct and consistent use of these methods can result in lower failure rates. In a clinical trial with Enskyce, 1,195 subjects completed 11,656 cycles and a total of 10 pregnancies were reported. This represents an overall user-efficacy (typical user-efficacy) pregnancy rate of 1.12 per 100 women-years. This rate includes patients who did not take the drug correctly. TABLE 1: PERCENTAGE OF WOMEN EXPERIENCING AN UNINTENDED PREGNANCY DURING THE FIRST YEAR OF TYPICAL USE AND THE FIRST YEAR OF PERFECT USE OF CONTRACEPTION AND THE PERCENTAGE CONTINUING USE AT THE END OF THE FIRST YEAR. UNITED STATES. % of Women Experiencing an Unintended Pregnancy within the First Year of Use % of Women Continuing Use at One Year 1 Emergency Contraceptive Pills: Treatment initiated within 72 hours after unprotected intercourse reduces the risk of pregnancy by at least 75%. 4 Lactation Amenorrhea Method: LAM is a highly effective, temporary method of contraception. 5 Source: Trussell J. Contraceptive efficacy. In Hatcher RA, Trussell J, Stewart F, Cates W, Stewart GK, Kowel D, Guest F, Contraceptive Technology: Seventeenth Revised Edition. New York, NY; Irvington Publishers, 1998. 1 Among couples attempting to avoid pregnancy, the percentage who continue to use a method for one year. 2 Among typical couples who initiate use of a method (not necessarily for the first time), the percentage who experience an accidental pregnancy during the first year if they do not stop use for any other reason. 3 Among couples who initiate use of a method (not necessarily for the first time) and who use it perfectly (both consistently and correctly), the percentage who experience an accidental pregnancy during the first year if they do not stop use for any other reason. 4 The treatment schedule is one dose within 72 hours after unprotected intercourse, and a second dose 12 hours after the first dose. The FDA has declared the following brands of oral contraceptives to be safe and effective for emergency contraception: Ovral ® (1 dose is 2 white pills), Alesse ® (1 dose is 5 pink pills), Nordette ® or Levlen ® (1 dose is 4 yellow pills). 5 However, to maintain effective protection against pregnancy, another method of contraception must be used as soon as menstruation resumes, the frequency of duration of breastfeeds is reduced, bottle feeds are introduced, or the baby reaches 6 months of age. 6 The percents becoming pregnant in columns (2) and (3) are based on data from populations where contraception is not used and from women who cease using contraception in order to become pregnant. Among such populations, about 89% become pregnant within one year. This estimate was lowered slightly (to 85%) to represent the percent who would become pregnant within one year among women now relying on reversible methods of contraception if they abandoned contraception altogether. 7 Foams, creams, gels, vaginal suppositories, and vaginal film. 8 Cervical mucus (ovulation) method supplemented by calendar in the pre-ovulatory and basal body temperature in the post-ovulatory phases. 9 With spermicidal cream or jelly. 1 0 Without spermicides.
