Danocrine (danazol) is a steroid used to treat endometriosis and fibrocystic breast disease. It is also used to prevent attacks of angioedema in people with an inherited form of this disorder. The brand name of this medication is discontinued, but generic versions may be available. Common side effects include acne or other skin problems; increased hair growth or hair loss; weight gain; breast changes; deepened voice; nervousness; increased sweating, warmth or tingly feeling under your skin; changes in your menstrual periods; or vaginal dryness, discomfort, or itching.

In moderate to severe disease, or in patients infertile due to endometriosis, a starting dose of 800 mg Danocrine given in two divided doses is recommended. The total daily dosage of Danocrine for fibrocystic breast disease ranges from 100 mg to 400 mg given in two divided doses depending upon patient response. Danocrine may interact with blood thinners, or carbamazepine. Tell your doctor all medications and supplements you use. Danocrine can cause birth defects. Do not use Danocrine if you are pregnant. Tell your doctor if you become pregnant during treatment. Before you start taking Danocrine, you may need to have a pregnancy test to make sure you are not pregnant. Use an effective barrier form of birth control (such as a condom or diaphragm with spermicide gel or inserts). Hormonal contraception (such as birth control pills, injections, implants, skin patches, and vaginal rings) may not be effective to prevent pregnancy during treatment. Breastfeeding is not recommended while using this drug.

SIDE EFFECTS

The following events have been reported in association with the use of DANOCRINE:

Androgen like effects include weight gain, acne and seborrhea. Mild hirsutism, edema, hair loss, voice change, which may take the form of hoarseness, sore throat or of instability or deepening of pitch, may occur and may persist after cessation of therapy. Hypertrophy of the clitoris is rare.

Other possible endocrine effects are menstrual disturbances including spotting, alteration of the timing of the cycle and amenorrhea. Although cyclical bleeding and ovulation usually return within 60-90 days after discontinuation of therapy with DANOCRINE, persistent amenorrhea has occasionally been reported.

Flushing, sweating, vaginal dryness and irritation and reduction in breast size, may reflect lowering of estrogen. Nervousness and emotional lability have been reported. In the male a modest reduction in spermatogenesis may be evident during treatment. Abnormalities in semen volume, viscosity, sperm count, and motility may occur in patients receiving long-term therapy.

Hepatic dysfunction, as evidenced by reversible elevated serum enzymes and/or jaundice, has been reported in patients receiving a daily dosage of DANOCRINE of 400 mg or more. It is recommended that patients receiving DANOCRINE be monitored for hepatic dysfunction by laboratory tests and clinical observation. Serious hepatic toxicity including cholestatic jaundice, peliosis hepatis, and hepatic adenoma have been reported. (See WARNINGS and PRECAUTIONS.)
