Levonorgestrel is an emergency contraceptive available without age restrictions in over-the-counter (OTC) medicines that help prevent pregnancy after unprotected sex or birth control failure. Levonorgestrel can be found in single-ingredient emergency contraceptive medicines.

Levonorgestrel is approved by the U.S. Food and Drug Administration (FDA) and is safe. It reduces the chance of pregnancy when taken as directed up to 72 hours after unprotected sex or birth control failure.

Levonorgestrel is not the abortion pill. Emergency contraceptives containing levonorgestrel should only be used in emergency situations. These medicines are not intended to be used in place of routine birth control methods because they are not as effective.
