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. An IUD can only be provided to those who have at least one child.

You may wish to consider having a supply of emergency contraceptive pill or pills at home so you have them easily available should you need them as they only work within five days of unprotected sex.



Emergency contraception works well at preventing a pregnancy after unprotected sex. In general the sooner an emergency contraceptive is used the more effective it is at stopping a pregnancy.


Emergency contraception pills are available at all our centres, as well as pharmacies across Bangladesh.
