Leuprolide is used to treat disorders of the uterus (e.g., endometriosis, fibroids) in women. It helps to reduce symptoms such as pelvic pain, painful/heavy menstrual periods, and abdominal bloating. It also shrinks the abnormal uterine tissue that causes these symptoms. For the treatment of fibroids, leuprolide is usually given with iron to help improve anemia that is caused by too much vaginal bleeding. Uterine tissue needs the female hormone estrogen to grow and spread. Leuprolide works by decreasing the amount of estrogen that is made in the female body.

Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

Leuprolide may also be used to stop early puberty (precocious puberty) in children. It helps to delay sexual development (e.g., growth of the breasts/testicles) and the start of menstrual periods. It also helps slow down the rate of early bone growth so that the chances for reaching normal adult height are increased. The doctor should consider stopping treatment before age 11 for girls and age 12 for boys. Leuprolide works by decreasing the amount of sex hormones that a child's body makes (estrogen in girls, testosterone in boys).
