There are two main types of morning after pill tablets on the market in the UK.

ellaOne

ellaOne is considered to be a highly effective form of emergency contraception. It’s 95% effective when used within 120 hours (5 days) of intercourse.

Levonelle

Levonelle diminishes in effectiveness over time. Taken up to 12 hours after unprotected sex, it is 95% effective, but only 58% effective after 48 to 72 hours (3 days).
