Gonadotropin – releasing hormone (GnRH) agonists can stop the menstrual cycle and shrink fibroids. For this reason they are sometimes used prior to surgery.
GnRH agonists act by causing a temporary and reversible menopause like state. This can cause flow on effects which can be problematic. For this reason, they are only used for short periods of time (for up to six months). Once the medication is discontinued, fibroids normally return to their previous size.
Other medications such as the combined oral contraceptive pill or progestogen releasing intrauterine device (IUD) are often trialed to control heavy bleeding and painful periods, prior to trialing GnRH agonists. They do not, however, shrink the size of the fibroid itself.
