Levonorgestrel is used by women to prevent pregnancy after birth control failure (such as a broken condom) or unprotected sex. This medication is an emergency contraceptive and should not be used as a regular form of birth control. It is a progestin hormone that works mainly by preventing the release of an egg (ovulation) during your menstrual cycle.
