What are danazol capsules?
DANAZOL (Danocrine®) slows production of the female hormone estrogen. Danazol is a man-made steroid that has similar actions to androgens, or male sex hormones. Danazol relieves the symptoms of endometriosis by shrinking the abnormal tissue, which forms a lining to the womb. Danazol can reduce the growth of abnormal breast tissue and is helpful in the treatment of fibrocystic breast disease. Danazol also treats a disorder that affects both men and women called hereditary angioedema, which causes swelling and pain in the arms, legs, face, throat, colon, or reproductive (sex) organs. Generic danazol capsules are available.
