For boys with severe gynecomastia that is causing substantial tenderness or embarrassment, a short course of a drug called tamoxifen (sample brand name: Nolvadex) or raloxifene (brand name: Evista) may be recommended. These drugs block the effects of estrogen in the body and can reduce the size of the breasts somewhat. However, neither of these drugs is approved in the United States for the treatment of gynecomastia. Drugs may be prescribed without US Food and Drug Administration (FDA) approval, although the risks and benefits have not been studied completely.
