Metadata[+] Show full item record
Lybrel(TM) (levonorgestrel and ethinyl estradiol) is currently marketed as the first FDA-approved oral contraceptive taken every day for 365 days without menstruation. However in clinical trials, more than 50% of women did not complete a year of treatment due to adverse effects, primarily spotting, bleeding, headache, and dysmenorrhea.
