Postinor 2 is an emergency contraception pill that you can take up to 72 hours after unprotected sex. The pill contains the hormone progesterone, which is a natural hormone your ovaries produce.
Progesterone is responsible for preparing the womb for pregnancy.

When taken as emergency contraception, progesterone works by delaying or preventing ovulation. It is about 85% effective in preventing pregnancy when taken as directed. Other progesterone-containing emergency birth control pills similar to Postinor 2 are:
- Postinor 1
- Levonelle
- Plan B
- Take Action
Postinor 2 is a well-known and effective emergency contraceptive pill. We often call it the ‘morning-after pill’. Postinor 2 contains the active ingredient levonorgestrel, which is a synthetic progestogen hormone. Levonorgestrel is similar to the natural progesterone hormone that your ovaries make.

Do I need a Doctor’s Consultation before I can get Postinor 2?
You can buy Postinor 2 over the counter from pharmacies. We consider it a safe and effective way to prevent pregnancy. However, it is not 100% effective.
It contains only progesterone and works by delaying ovulation, preventing the egg from release into the fallopian tube, where sperm can fertilise it.
Postinor 2 is more effective the sooner it is taken after unprotected sex. It is most effective if taken within 12 hours but can be taken up to 72 hours after unprotected sex.
Most women can use progesterone-only containing medicines like Postinor 2 without a doctor’s assessment or prescription. However, if you have the following medical problems, you should consult your doctor to be sure it is safe to use Postinor 2:
