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.
ULIPRISTAL SHOULD NOT BE USED TO TERMINATE AN EXISTING PREGNANCY.
Ulipristal may also be used for purposes not listed in this medication guide.
Ulipristal is not to be used as a regular form of daily, weekly, or monthly birth control.
Ulipristal can harm an unborn baby or cause birth defects. Do not use if you are already pregnant or think you might be pregnant.

How should I take ulipristal?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Ulipristal is usually given as soon as possible after unprotected sex or failed birth control method (such as a condom that broke during sex). Follow your doctor's dosing instructions very carefully. Ulipristal can be taken any time during your menstrual cycle, but you must use the medicine within 5 days (120 hours) after unprotected sex.
If you vomit within 3 hours after taking ulipristal, your medication may not be as effective. Call your doctor to discuss the need for taking another ulipristal tablet.
You may take ulipristal with or without food.
You should wait at least 5 days after taking ulipristal before you start using hormonal birth control (birth control pills, injections, implants, skin patches, vaginal rings). Both ulipristal and hormonal birth control may be less effective when used at the same time. You may need to use a barrier form of birth control until your hormonal birth control takes effect.
Store ulipristal in the original container at room temperature, away from moisture, heat, and light.
Contact your doctor if your next menstrual period is more than 1 week late. You will need a pregnancy test to make sure you are not pregnant. Do not take a second course of ulipristal.

Since ulipristal is used only once when needed, it does not have a daily dosing schedule.
