Norgestrel

Generic name: Norgestrel
Drug class: Progestins

Usage of Norgestrel

Norgestrel is used to prevent pregnancy. It works by stopping a woman's egg from fully developing each month. The egg can no longer accept a sperm and fertilization (pregnancy) is prevented.

No contraceptive method is 100 percent effective. Birth control methods such as having surgery to become sterile or not having sex are more effective than birth control pills. Discuss your options for birth control with your doctor.

This medicine does not protect against HIV infection or other sexually transmitted diseases. It will not help as emergency contraception, such as after unprotected sexual contact.

This medicine is available over-the-counter.
