Some adolescents use progestin only contraceptive products because of an underlying medical condition; others simply prefer them. Current options include pills, a long -acting intramuscular injection, an implant, and a progestin-releasing intrauterine device. Also available is Plan B, a progestin only emergency contraceptive option. Although these products vary in efficacy, they are generally safe and well tolerated by adolescents. The implants and intramuscular injections are particularly well suited for adolescent use because of their need for little compliance, well-tolerated adverse effect profile, and excellent efficacy rates.
