Seasonique is "the next generation" of Seasonale, an extended-cycle
birth control pill launched in 2003, states a news release from Barr
Pharmaceuticals, the parent company of Duramed Pharmaceuticals, which makes
Seasonique and Seasonale.
Seasonique will be available by prescription in July, states a Barr
Pharmaceuticals news release announcing the drug's approval. Seasonique is more
than 99% effective at preventing pregnancy when taken as
directed, states Barr Pharmaceuticals' news release.
Seasonique was tested in a study of about 2,500 U.S. women aged 18-40 who
took the drug for 12 months (four cycles, each lasting 91 days), the news
release states. Side effects were similar to those seen in trials of other oral
contraceptives, according to Barr Pharmaceuticals.
Seasonique vs. Seasonale
What's the difference between Seasonique and Seasonale? Both drugs are
designed to give women four periods per year instead of 12. With Seasonale,
women take inactive pills during their four yearly periods. With Seasonique,
they get a low dose of estrogen during their period, which may provide benefits
including less breakthrough bleeding, Barr Pharmaceuticals spokeswoman Carol
Cox tells WebMD.
Users of extended-cycle birth control pills may be more likely to experience
bleeding or spotting between periods; such bleeding and spotting tends to
decrease during later cycles as women keep taking the drug.
"Oral contraceptives are not for every woman," states Barr
Pharmaceuticals' news release.
"Serious as well as minor side effects have been reported with the use
of hormonal contraceptives," the release continues. "Serious risks
include blood clots, strokestroke, and heart attackheart attack. Cigarette smoking increases the risk
of serious cardiovascular side effects, especially in women over 35
Oral contraceptives don't protect against HIV -- the virus that causes AIDS
-- or other sexually transmitted diseases, the news release also notes.
