The morning-after pill should be taken as soon as possible after unprotected sex for the best effectiveness. The specific timing depends on the type of pill used:
- Pills containing levonorgestrel should be taken within 72 hours (3 days) after unprotected intercourse. They work best if taken within the first 24 hours but can still be effective up to 3 days.
- Pills containing ulipristal acetate can be taken up to 120 hours (5 days) after unprotected sex and are effective for a longer window than levonorgestrel pills.
It is crucial to take the pill promptly as delaying reduces its effectiveness, and if vomiting occurs within a few hours of taking the pill, a repeat dose may be necessary. The morning-after pill is an emergency contraceptive and is most effective the sooner it is taken after unprotected sex.
