7.3.5 Emergency contraception

Ulipristal is more effective than levonorgestrel at preventing pregnancy between 72 and 120 hours after unprotected sex.

Women who do not experience a normal period within 3 weeks of using EHC should be followed up so that pregnancy can be excluded.

A copper IUCD is more effective than levonorgestrel but its effectiveness compared to ulipristal is unknown. It can be inserted up to 5 days after unprotected sexual intercourse or up to 5 days after the earliest likely day of ovulation (i.e. before implantation). The IUCD can then be removed with the next period or left in situ for long-term contraception.
