Ulipristal is used by women to prevent pregnancy after birth control failure (such as a broken condom) or unprotected sex. This medication is an emergency contraceptive and should not be used as a regular form of birth control. It works mainly by preventing the release of an egg (ovulation) during your menstrual cycle. It also makes vaginal fluid thicker to help prevent sperm from reaching an egg (fertilization) and changes the lining of the uterus (womb) to prevent attachment of a fertilized egg.
This medication may not work well in women who are overweight (for example, body mass index greater than 30). Talk to your doctor for more details and to see if this medication is right for you.
Read the Patient Information Leaflet if available from your pharmacist before you start taking ulipristal. If you have any questions, ask your doctor or pharmacist.
Take 1 tablet by mouth with or without food as directed by your doctor as soon as possible after unprotected sex. This medication works best when it is taken within 120 hours (5 days) after unprotected sex.
If you vomit within 3 hours of taking this medication, contact your doctor to ask if you need to repeat the dose.
After you take this medication, the time when your period comes and how much you bleed may change. Tell your doctor right away if your period is more than 7 days late. You may need to take a pregnancy test.
After using this medication, you should use a barrier-type birth control (such as condoms, diaphragm) every time you have sex until you have your period. If you use or wish to use hormonal birth control, wait at least 5 days after using this medication before starting hormonal birth control (since these medications may interact and make both drugs work less well). Continue using a barrier-type birth control until your hormonal birth control takes effect. If needed, talk to your doctor about reliable forms of birth control.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
