Desogestrel

INDICATIONS AND USAGE Volnea™ (desogestrel and ethinyl estradiol and ethinyl estradiol) tablets are indicated for the prevention of pregnancy in women who elect to use this product as a method of contraception. Oral contraceptives are highly effective. Table 2 lists the typical accidental pregnancy rates for users of combination oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization, depends upon the reliability with which they are used. Correct and consistent use of these methods can result in lower failure rates. TABLE 2 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 Among couples attempting to avoid pregnancy, the percentage who continue to use a method for one year. Method (1) Typical Use 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. (2) Perfect Use 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. (3) (4) Chance 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

DOSAGE AND ADMINISTRATION To achieve maximum contraceptive effectiveness, Volnea™ (desogestrel and ethinyl estradiol and ethinyl estradiol) tablets must be taken exactly as directed and at intervals not exceeding 24 hours Volnea ™ may be initiated using either a Sunday start or a Day 1 start. NOTE: Each blister card 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 blister card 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 Volnea ™ should be considered. The use of Volnea™ 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 Volnea™ postpartum, and has not yet had a period, she should be instructed to use another method of contraception until a 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 tablet should be taken on the first Sunday after menstruation begins (if menstruation begins on Sunday, the first white tablet is taken on that day). One white tablet is taken daily for 21 days, followed by 1 green (inert) tablet daily for 2 days and 1 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 yellow tablet. [If switching from a Sunday Start oral contraceptive, the first Volnea™ (desogestrel/ethinyl estradiol and ethinyl estradiol) 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 tablet, she should take the missed tablet as soon as she remembers. If the patient misses 2 consecutive 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 tablets in the third week or misses 3 or more white tablets in a row at any time during the cycle, the patient should keep taking 1 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 tablet daily for 21 days, one green (inert) tablet daily for 2 days followed by 1 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 yellow tablet. [If switching directly from another oral contraceptive, the first white tablet should be taken on the first day of menstruation which begins after the last ACTIVE tablet of the previous product.] If a patient misses 1 white tablet, she should take the missed tablet as soon as she remembers. If the patient misses 2 consecutive 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 tablets in the third week or if the patient misses 3 or more white tablets in a row at any time during the cycle, 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. ALL ORAL CONTRACEPTIVES 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, non-functional causes should be

ADVERSE REACTIONS 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 1). 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 1: 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.
