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.
You may still get pregnant if there is sexual intercourse after taking the pill. Use a condom or any other type of birth control method if you have sexual intercourse after taking the emergency contraceptive pill.
The tablet works best the sooner you take it after having unprotected sex. It can only reduce the likelihood of becoming pregnant, if you take it within 72 hours of unprotected sex. Please contact your healthcare professional if it is more than 72 hours since unprotected sex.
