Postinor-2 is an emergency contraceptive pill that is used to prevent pregnancy when taken within 72 hours of unprotected intercourse

. It is not intended as a regular method of contraception and should only be used as an emergency measure

. The active ingredient in Postinor-2 is levonorgestrel, which is thought to work mainly by preventing ovulation and fertilization if intercourse has taken place in the current menstrual cycle

. It is not known exactly how this medication works, but it is thought to reduce the chance of pregnancy in two ways: if taken before ovulation, it may delay the release of the egg, and if taken after ovulation, it may interfere with the transport of eggs and sperm

. It is important to note that Postinor-2 will not prevent sexually transmitted infections (STIs)
