Emergency contraception

Providing pregnancy prevention after unprotected sex.

A short-term method of contraception.

Emergency contraception pills help to prevent a pregnancy when taken up to five days after unprotected sex.

They work by preventing or delaying the release of an egg from the ovaries. A very popular type of emergency contraception involves taking one or two tablets of a particular hormone. This is sometimes called ‘the morning after pill’ or ‘Plan B’.

An intrauterine device (IUD) can also be used as emergency contraception as it can prevent a fertilised egg from settling in the womb.
