Triptorelin belongs to a class of medications called gonadotropin-releasing hormone (GnRH) agonists. It works by balancing your hormones and treating conditions related to hormone levels in your body. It is used alone or together with surgery or radiation therapy to treat prostate cancer. It is also used in the treatment of early-stage breast cancer with other medications. Endometriosis (a condition in which the tissue that normally lines the inside of the uterus grows in other places), uterine fibroids (abnormal non-cancerous growths in the uterus) and central precocious puberty (premature puberty in children) may also be treated using Triptorelin.
Triptorelin is injected into a muscle or the fatty layer under the skin via a needle as directed by your doctor. Triptorelin is available in two chemical forms, triptorelin acetate and triptorelin embonate, which require different dosages in treating different conditions. Your doctor will advise you on the dosage and frequency depending on your condition.
