Issues in emergency contraception for the adolescent
AbstractBefore prescribing emergency contraception, it is important to establish that unprotected coital intercourse has indeed taken place. Young naive adolescents sometimes think that heavy petting, touching, kissing or oral sex can lead to pregnancy. Conversely, sexual encounter without penetration but with ejaculation around the female genitalia can occasionally result in pregnancy. Next, it is important to ensure that she is not already pregnant because emergency contraception will not be effective then. Following that, it is important to determine the duration lapsed since the unprotected coitus. This is to determine whether emergency contraception is still possible and the appropriate emergency contraceptive method to recommend. Emergency contraception with high-dose combined (oestrogen & progestogen) contraceptive pills or progestin-only pills are effective up to 72 hours after unprotected coitus with effectiveness highest if used as soon as possible after coitus.1-3 Emergency contraceptive pills (ECP) should not be given to women who are already pregnant as the pills would no longer be effective. Otherwise, there are no other contraindications unlike regular hormonal contraception.1,3,4 Levonorgestrel (LNG) pills can still be prescribed up to 120 hours after coitus,1,3,4 but its effectiveness falls rapidly after 72 hours (copied from article)
