Postinor-2 is an emergency contraceptive, also known as the ‘morning-after pill’. It is a form of contraceptive that is used after sex, and helps prevent pregnancy when no other forms of pregnancy-prevention techniques were used prior to having sex.

​Postinor-2 ( levonorgestrel), is a safe and effective way to prevent pregnancy after unprotected sexual intercourse. It comes in two pills that are taken within 72 hours after sex. However, because of its easy use, accessibility, and the belief that it prevents pregnancy, a lot of females take this drug regularly in so as not to get pregnant. Although, it's very important you note that Postinor-2 as an emergency contraceptive only and it's not meant to be taken regularly. 

The medication is meant to serve as an emergency for those very rare times such as; if she forgot to take her birth control pills, if the condom broke or slipped off during sexual intercourse, if no birth control methods were used, or you are not certain about the effectiveness of some other form of contraceptive you are using. 

What Postinor-2 is used for

Postinor-2 is an emergency contraceptive only. Postinor-2 is not intended as a regular method of contraception. It is used to prevent pregnancy when taken within 72 hours of unprotected intercourse. It is estimated that Postinor-2 will prevent 85% of expected pregnancies. 95% of expected pregnancies will be prevented if taken within the first 24 hours, declining to 58% if taken between 48 hours and 72 hours after unprotected intercourse. 

It is not known whether Postinor-2 is effective if taken more than 72 hours after unprotected intercourse.
