Ulipristal Acetate Overview

  • Ulipristal is used to prevent pregnancy after unprotected sexual intercourse (sex without any method of birth control or with a birth control method that failed or was not used properly [e.g., a condom that slipped or broke or birth control pills that were not taken as scheduled]). Ulipristal should not be used to prevent pregnancy on a regular basis. This medication is to be used as an emergency contraceptive or backup in case regular birth control fails or is used incorrectly. Ulipristal is in a class of medications called progestins. It works by preventing or delaying the release of an egg from the ovary. It also may work by changing the lining of the uterus (womb) to prevent development of a pregnancy. Ulipristal may prevent pregnancy, but it will not prevent the spread of human immunodeficiency virus (HIV, the virus that causes acquired immunodeficiency syndrome [AIDS]) and other sexually transmitted diseases.
