Ulipristal is a prescription medication used to treat certain types of uterine fibroids in women. It is a type of selective progesterone receptor modulator (SPRM). Ulipristal works by blocking the action of progesterone, a hormone that helps to regulate the menstrual cycle and fibroid growth. This medicine helps to reduce the size of fibroids, and can also reduce heavy bleeding and pain associated with the condition. Common side effects of Ulipristal include headache, nausea, breast tenderness, abdominal pain, and diarrhea.
Ulipristal is a medication with two main applications:
- Emergency Contraception: It is used to prevent pregnancy after unprotected sexual intercourse (sex without any birth control or with a birth control method that failed or wasn't used properly).
- Treatment of Uterine Fibroids: Ulipristal is also used under the brand name Fibristal to manage uterine fibroids, which are noncancerous growths in the uterus.
Here's a breakdown of its key functionalities:
Emergency Contraception:
- Works by delaying or preventing ovulation (the release of an egg from the ovary).
- Effective for up to 5 days (120 hours) after unprotected intercourse, but the sooner it's taken, the better the chance of preventing pregnancy.
- Sold under the brand name Ella (in the US) as a single-dose tablet.
Treatment of Uterine Fibroids:
- Helps to shrink fibroids and reduce bleeding associated with them.
- Typically taken for up to 3 months, but a doctor will determine the appropriate treatment course.
