NAFARELIN treats the symptoms of
endometriosis. It works by decreasing the amount of
estrogen your body makes, which reduces
heavy bleeding and
pain. It may also be used to treat a condition that causes
early puberty. It works by decreasing levels of the hormones estrogen and
testosterone in the body. This slows or stops signs of puberty while you are taking this medication. With the Patient Assistance Program from Pfizer, you can receive your medication at no cost.
