Seasonique is manufactured by Duramed Pharmaceuticals, a wholly owned subsidiary of Teva Pharmaceutical Industries.
Seasonique is a 91-day regimen, taken daily as 84 days of combination 0.15mg levonorgestrel/ 0.03mg ethinyl estradiol followed by 7 days of ultra low dose (0.01mg) unopposed ethinyl estradiol, during which time a woman would have her period.
Paladin Labs president and CEO Jonathan Ross Goodman said they believe that this oral contraceptive option will be the preferred choice of many Canadian women who need contraception and are interested in the lifestyle benefits of fewer periods per year.
