SEASONIQUE SUMMARY
SEASONIQUETM
(levonorgestrel / ethinyl estradiol tablets) 0.15 mg / 0.03 mg and
(ethinyl estradiol tablets) 0.01 mg
SeasoniqueTM (levonorgestrel/ethinyl estradiol combination tablets and ethinyl estradiol tablets) is an extended-cycle oral contraceptive consisting of 84 light blue-green tablets each containing 0.15 mg of levonorgestrel, a synthetic progestogen and 0.03 mg of ethinyl estradiol, and 7 yellow tablets containing 0.01 mg of ethinyl estradiol.
SeasoniqueTM tablets are indicated for the prevention of pregnancy in women who elect to use oral contraceptives as a method of contraception.
Clinical Studies
PSE-301 was a randomized, multicenter, open-label study designed to evaluate the safety and efficacy of SeasoniqueTM for approximately 1 year (four 91-day SeasoniqueTM extended cycles). A total of 1,006 sexually active adult women of childbearing potential, 18 to 40 years of age, were treated and completed 2,488 SeasoniqueTM 91-day cycles. The principal cohort for efficacy included only patients 18 to 35 years of age who completed at least one 91-day cycle treatment cycle. Cycles in which another form of birth control was used (including condoms) were excluded from the efficacy analysis. The overall Pearl Index was 1.77, based on 7 pregnancies in 1,578 completed 91-day treatment cycles.
Oral contraceptives are highly effective for pregnancy prevention. Table 2 lists the typical unintended pregnancy rates for users of combination oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization, the IUD, and Norplant® Implant System, depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates.
