When can I take Levonorgestrel?
Levonorgestrel is a morning after pill that should be taken within 72 hours (3 days) of unprotected sex.
How does Levonorgestrel work?
Levonorgestrel is a synthetic (man-made) hormone and the active ingredient in this emergency contraception pill. It works to prevent pregnancy in two different ways. Either by stopping the ovaries releasing an egg (ovulating) or if an egg has already been released it stops sperm reaching an egg and fertilising it.
How effective is the morning after pill Levonorgestrel?
The earlier Levonorgestrel is taken after unprotected sex, the more likely it is to be effective. It should be taken within 72 hours (3 days), but it is thought that if taken:
- within 24 hours it will prevent 95% of pregnancies
- within 48 hours it will prevent 85% of pregnancies
- within 72 hours prevent 58% of pregnancies
If you are sick within three hours of taking the initial tablet you will need to take another Levonorgestrel pill. You should also speak to a medical professional.
Once you have taken Levonorgestrel it will not prevent further pregnancies if you have unprotected sex again. Between taking the tablet and your next period you should use condoms or your regular contraception.
