European Active Surveillance Study Comparing Regimens of Administration in Combined Hormonal Contraception

This study compares the risks of short- and long-term use of FC Patch Low with levonorgestrel-containing combined oral contraceptives (COC-LNG) in a study population representative of the actual users of the individual preparations. FC Patch Low is a transdermal contraceptive patch applied once a week for three consecutive weeks followed by a break of one week (21/7). One patch contains 2.1mg gestodene and 0.55mg ethinyl estradiol, which is equivalent of releasing 0.06mg gestodene and 0.013mg ethinyl estradiol per 24 hours.
