We recruited adolescents to study oral contraceptives versus placebo for dysmenorrhea. We anticipated high discontinuation and concerns about safety, side effects, and sexual behavior. Treatment discontinuation (11%) and loss to follow-up (1%) were lower than expected. The most common reason for nonenrollment was logistical issues (63%). Most participants remained abstinent.
