Nafarelin is a gonadotropin-releasing hormone agonist (GnRH agonist). By causing constant stimulation of the pituitary gland, it decreases pituitary secretion of the gonadotropins luteinizing hormone (LH) and follicle stimulating hormone (FSH). Nafarelin may be used in the treatment of estrogen-dependent conditions (such as endometriosis or uterine fibroids), to treat central precocious puberty, or to control ovarian stimulation in IVF.
Side effects of nafarelin are related to the low estrogen state. Side effects include hot flashes, vaginal dryness, headaches, mood changes, and decreased interest in sex. Some patients may experience acne, muscle pain, reduced breast size, and irritation of the tissue inside the nose. These side effects are reversible and should resolve after stopping the medication.
