reproductive system and the development of the male characteristics, such as facial hair and a deep voice. The ovaries also produce small amounts of androgens.

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Danazol may cause male-like changes in female children and cause premature sexual development in male children. It may also slow or stop growth in any child.
Geriatric
Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. Although there is no specific information comparing use of danazol in the elderly with use in other age groups, danazol has effects similar to androgens (male hormones). Androgens used in older males may increase the risk of developing prostate enlargement or cancer.
