The morning after pill, levonorgestrel, should be taken within 72 hours (3 days) of unprotected sex.
Levonorgestrel is a synthetic hormone and the active ingredient in this form of emergency contraception. It works in two ways to prevent pregnancy: either by preventing the ovaries from ovulating or by preventing sperm from fertilizing an egg that has already been released.
The earlier Levonorgestrel is administered after unprotected sex, the more effective it will be. It should be taken within 72 hours (3 days), but it is thought that taking it within 24 hours will prevent 95% of pregnancies, 48 hours will prevent 85% of pregnancies, and 72 hours will prevent 58 percent of pregnancies.
If you get sick within three hours of taking the first tablet, you’ll need to take another Levonorgestrel.
If you have unprotected sex again after taking Levonorgestrel, it will not prevent further pregnancies. Use condoms or your regular contraception between taking the tablet and your next period.
1.5 milligrams of Levonorgestrel is the usual dose. However, some women may require a double dose (3mg Levonorgestrel) to achieve the desired results. This could be due to your weight (if you weigh more than 70 kilograms) or the medications you’re taking.
When taking Levonorgestrel, like most medications, some people may experience side effects. Nausea, stomach pain, and headaches are the most common side effects of this type of emergency contraception.
If your period is late after taking Levonorgestrel and you have the symptoms listed above, you should get a pregnancy test.
See the patient information leaflet for a complete list of side effects and how to use it correctly. If you have any concerns about side effects, please contact us through your Patient Record.
It’s critical that you tell us about any other medications or recreational drugs you’re taking so that Levonorgestrel can be safely prescribed. Most medications can be taken with levonorgestrel, but some medications may interact with it.
