Seasonique (Levonorgestrel / Ethinyl Estradiol / Ethinyl Estradiol) - Summary



Cigarette smoking increases the risk of serious cardiovascular side effects from oral contraceptive use. This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years of age. Women who use oral contraceptives should be strongly advised not to smoke.



(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.
