Ulipristal is used to treat fibroids in the uterus by women of child-bearing age who are eligible for surgery. This medication is different from the hormone (such as progestin) that your body normally makes. Ulipristal works by acting like a type of progestin (such as progesterone). Ulipristal belongs to a class of drugs known as selective progesterone receptor modulators or SPRMs. It helps to reduce pain/discomfort and heavy menstrual bleeding caused by uterine fibroids.
