title: Sometimes You Do Get a Second Chance: Emergency Contraception for Adolescents.
abstract: Unplanned or unintended pregnancy remains a significant challenge for adolescents; many teens who plan ahead but opt not to choose long-acting reversible contraceptive methods have high failure rates with condom usage, oral contraceptives, and other less long-acting methods. Emergency contraception (EC) remains a necessity for those adolescents seeking a second chance to prevent the unintended consequences of unplanned sexual activity. At present, 5 postcoital methods remain available as EC globally: intrauterine devices, ulipristal acetate, a selective progesterone modulator, mifepristone; levonorgestrel, and ethinyl estradiol plus levonorgestrel or norgestrel (rarely used now that progestin only methods are more readily available).
