**RECOMMENDED DOSAGE:** In women of reproductive age, therapy should begin during menstruation. A sensitive test (eg. beta subunit test if available) capable of determining early pregnancy is recommended immediately prior to start of therapy. Additionally, a non-hormonal method of contraception should always be used during Danazol therapy (See Warnings – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). **Endometriosis**: 200–800 mg danazol daily in two to four divided doses. It is recommended that treatment be initiated with a dosage of 800 mg daily in 4 divided doses. In some patients, it may be possible to maintain improvement with a reduced dosage once a satisfactory response has been obtained. Treatment should continue uninterrupted for 3 to 6 months, but may be extended to 9 months if necessary. **Menorrhagia**: A course of 200–400 mg danazol daily in divided doses for up to 6 months. 200 mg is usually sufficient to reduce menstrual blood flow to acceptable limits. **Fibrocystic Breast Disease**: The minimum effective dose should be used. 200 mg daily is an effective dose in the majority of patients. In some instances, 400 mg/day may be warranted. **Hereditary Angioedema**: 200–600 mg danazol daily in divided doses. Dosage should be kept as low as possible with adjustment to meet individual patient requirements. Consideration should be given to interrupting treatment after an attack-free period.
