Drug Class: Commonly Known As: Category:
Postinor-2

Levonorgestrel - What is it for

​There are 2 types of emergency contraception; the pill method and the insertion of a device called the copper intrauterine device (IUD). A copper IUD can prevent pregnancy because its presence is toxic to sperms. A woman might use emergency contraception if she forgot to take her birth control pills, if the condom broke or slipped off during sexual intercourse, or if no birth control methods were used.

Postinor-2, also known as “Morning-After Pill”, is one of the pill methods. It is a safe and effective way to prevent pregnancy after unprotected sexual intercourse.
