How many times can I use emergency contraception – the morning-after pill?
In theory you can use emergency contraception pills as many times as you need to use them. However, in practice it is much better to use a regular contraceptive pill (either the combined pill or the mini-pill) as these are more likely to prevent a pregnancy. The emergency pill works well if taken as soon as possible after sex but it can be used any time up to 72 hours after sex.
