TRENTON, N.J. (AP) — U.S. regulators have approved a new treatment for pain caused by endometriosis.
The common condition involves abnormal tissue growth from the uterus that can cause pain and infertility.
Drugmaker Abbvie said Tuesday that the Food and Drug Administration approved its drug, Orilissa (oh-RAH’-liss-ah), for pain during menstruation and at other times. The company says it’s the first new pill for endometriosis in a decade.
In testing, it significantly reduced menstrual pain in about 45 percent of women given a low dose and 75 percent given a high dose, compared to about 20 percent of women given dummy pills.
The drug works by reducing production of the hormone estrogen. That caused side effects in some participants, including hot flashes and bone thinning.
Orilissa will cost every four weeks without insurance.
