What is ulipristal?
Ulipristal is an emergency contraceptive. It works by stopping or delaying the release of an egg from an ovary. Ulipristal may also make it harder for a fertilized egg to attach to the uterus.
Ulipristal is used to prevent pregnancy after having sex without using a condom or other effective birth control method. Ulipristal is also used to prevent pregnancy after a regular form of birth control has failed. Ulipristal is not to be used as a regular form of daily, weekly, or monthly birth control.
