            Warnings

            Black Box Warnings

            A sensitive test (eg, beta subunit test if available) capable of determining early pregnancy recommended immediately prior to start of therapy; non-hormonal method of contraception should be used during therapy

            If patient becomes pregnant while receiving therapy, administration of the drug should be discontinued and the patient should apprised of potential risk to fetus

            Experience with long-term therapy is limited; peliosis hepatis and benign hepatic adenoma observed with long-term use; peliosis hepatis and hepatic adenoma may be silent until complicated by acute, potentially life-threatening intraabdominal hemorrhage; the physician should be alert to this possibility

            Attempts should be made to determine the lowest dose that will provide adequate protection; if the drug was begun at a time of exacerbation of hereditary angioneurotic edema due to trauma, stress or other cause, periodic attempts to decrease or withdraw therapy should be considered

            Danazol has been associated with several cases of benign intracranial hypertension also known as pseudotumor cerebri; early signs and symptoms of benign intracranial hypertension include papilledema, headache, nausea, vomiting, and visual disturbances; patients with these symptoms should be screened for papilledema and, if present, the patients should be advised to discontinue danazol immediately and be referred to a neurologist for further diagnosis and care

            Contraindications

            Pregnancy, breastfeeding

            Porphyria

            Undiagnosed abnormal genital bleeding

            Severe liver/renal/cardiac disease

            Androgen-dependent tumor

            Active thrombosis or thromboembolic disease and history of such events

            Hypersensitivity

            Cautions

            A temporary alteration of lipoproteins in the form of decreased high-density lipoproteins and possibly increased low-density lipoproteins reported during therapy

            These alterations may be marked, and prescribers should consider potential impact on risk of atherosclerosis and coronary artery disease in accordance with potential benefit of therapy to the patient

            Before initiating therapy of fibrocystic breast disease, carcinoma of the breast should be excluded; however, nodularity, pain, tenderness due to fibrocystic breast disease may prevent recognition of underlying carcinoma before treatment is begun

            If any nodule persists or enlarges during treatment, carcinoma should be considered and ruled out; patients should be watched closely for signs of androgenic effects some of which may not be reversible even when drug administration is stopped

            Because this drug may cause some degree of fluid retention, conditions that might be influenced by this factor, such as epilepsy, migraine, cardiac, or renal dysfunction, polycythemia, and hypertension require careful observation

            Use with caution in patients with diabetes mellitus; since hepatic dysfunction manifested by modest increases in serum transaminases levels reported in patients receiving therapy, periodic liver function tests should be performed

            Administration of this drug has been reported to cause exacerbation of manifestations of acute intermittent porphyria; laboratory monitoring of hematologic state should be considered

            Drug interaction overview

            • Prolongation of prothrombin time occurs in patients stabilized on warfarin
            • Therapy may cause an increase in carbamazepine levels in patients taking both drugs
            • This drug can cause insulin resistance; use caution when using with antidiabetic drugs
            • This drug may raise plasma levels of cyclosporin and tacrolimus, leading to an increase of renal toxicity of these drugs; monitoring of systemic concentrations of these drugs and appropriate dose adjustments may be needed when used concomitantly with danazol
            • Danazol can increase the calcemic response to synthetic vitamin D analogs in primary hyperparathyroidism; the risk of myopathy and rhabdomyolysis is increased by concomitant administration of danazol with statins such as simvastatin, atorvastatin, and lovastatin; caution should be exercised if used concomitantly
            • Consult the product labeling for statin drugs for specific information on dose restrictions in presence of this drug

            Pregnancy & Lactation

            Pregnancy

            Exposure to drug in utero may result in androgenic effects on female fetus; clitoral hypertrophy, labial fusion, urogenital sinus defect, vaginal atresia, and ambiguous genitalia reported

            Administered orally to pregnant rats from the 6th through the 15th day of gestation at doses up to 250 mg/kg/day (7-15 times the human dose) did not result in drug-induced embryotoxicity or teratogenicity, nor difference in litter size, viability, or weight of offspring compared to controls

            In rabbits, the administration of this drug on days 6-18 of gestation at doses of 60 mg/kg/day and above (2-4 times the human dose) resulted in inhibition of fetal development

            Lactation

            Contraindicated in breastfeeding patients

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

If you become pregnant or think you may be pregnant, tell your doctor right away.Danazol has rarely caused very serious (possibly fatal) blood clots (such as stroke), liver disease, and increased pressure on the brain (benign intracranial hypertension). Get medical help right away if you have any symptoms of these side effects, including nausea/vomiting that doesn't stop, headache that is severe or doesn't go away, weakness on one side of the body, trouble speaking, vision changes, severe stomach/abdominal pain, dark urine, yellowing eyes/skin, mental/mood changes (such as confusion).

            USES: This medication is used in women to treat pelvic pain and infertility due to a certain disorder (endometriosis) and also to treat breast pain/tenderness/nodules due to a certain breast condition (fibrocystic breast disease). It is also used in both men and women to prevent swelling of the abdomen/arms/legs/face/airway due to a certain congenital disease (hereditary angioedema).Danazol is an androgen similar to testosterone. For the treatment of endometriosis and fibrocystic breast disease, it works by decreasing the amount of hormones made by the ovaries. These hormones usually make the conditions worse. For the treatment of angioedema, danazol helps to increase the amount of a certain protein in your body's defense system (immune system).

            HOW TO USE: Take this medication by mouth as directed by your doctor, usually twice daily.
