Endometriosis is a condition that may involve the ovaries, fallopian tubes, or tissue around the pelvis. With this condition, the tissue that usually lines the inside of the uterus grows outside of the uterus. It may be caused by the flow of menstrual blood through the fallopian tubes and pelvis instead of out of the body. Endometriosis may also be caused by an immune system disorder that keeps the body from destroying the tissue outside of the uterus. Symptoms of endometriosis may include painful periods and diarrhea.
Medications that can decrease pain or slow endometrial tissue growth may be used to manage this condition. Naproxen (Aleve) may be used to ease the pain of menstrual cramps. Side effects may include nausea. To block the growth of endometrial tissue, danazol (Danocrine) may also be used. Danazol may also prevent menstruation and the symptoms of endometriosis. Side effects of danazol include flushing.
