It is a selective progesterone receptor modulator (SPRM) that affects the progesterone receptors in the body. It can be used as an emergency contraceptive pill when taken within 120 hours (5 days) of unprotected sexual intercourse or contraceptive failure. This medication is also used to treat moderate to severe symptoms of uterine fibroids in adult women.

It helps to shrink the fibroids and reduce these symptoms. Deereg Tablet is available by prescription only.
