What is levonorgestrel emergency contraceptive (Next Choice, Plan B, Plan B One-Step)?
Levonorgestrel is a female hormone that prevents ovulation (the release of an egg from an ovary). This medication also causes changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.
Levonorgestrel emergency contraceptive is used to prevent pregnancy after unprotected sex or failure of other forms of birth control (such as condom breakage, or missing 2 or more birth control pills).
Levonorgestrel emergency contraceptive may also be used for other purposes not listed in this medication guide.
