Emergency contraception (“the morning-after pill”) prevents unintended pregnancy after unprotected sex or contraceptive failure. The most-used method worldwide is single-dose levonorgestrel — most effective within 12 hours of unprotected sex, less effective beyond 72 hours but still licensed up to 72 hours. Ulipristal acetate is an alternative effective up to 120 hours but requires prescription in most jurisdictions. The most effective emergency contraception is the copper IUD inserted within 5 days (over 99% effective vs ~85% for oral options).
Op voorraad optie. Levonorgestrel 1.5 mg single-dose tablet. Stocked as i-pill. Take as soon as possible after unprotected sex — efficacy decreases over time. If vomiting occurs within 2 hours of taking, repeat the dose. Resume regular contraception (or start a new method) after the emergency dose. See also Postpone 72 in our Alternative Contraceptives catalogue.
How it works. Levonorgestrel emergency contraception primarily works by delaying ovulation — therefore most effective when taken before ovulation has occurred. It does NOT terminate an established pregnancy (unlike misoprostol/mifepristone). Higher BMI may reduce efficacy — ulipristal or copper IUD preferred where BMI > 26 and same-day access is feasible.
Belangrijk. Take the next regular pill at the usual time after using emergency contraception; use additional barrier protection until next period or for 7 days (depends on contraceptive method). Period may be a few days early or late after using emergency contraception. If period is more than 7 days late, do a pregnancy test. Recurrent need for emergency contraception suggests need for more reliable ongoing contraception — see our Anticonceptiepil en Alternatieve anticonceptiemiddelen categories. Emergency contraception does not protect against STIs — use barrier protection or get tested.
