Uses

1. Endometriosis

Danazol is used to treat endometriosis that is appropriate for hormonal management. It suppresses ovarian hormone activity and reduces stimulation of endometrial tissue outside the uterus.

Danazol may be used for symptomatic fibrocystic breast disease, particularly when breast pain, tenderness, or nodularity requires medical treatment and other measures have not provided sufficient control.

3. Prevention of Hereditary Angioedema Attacks

Danazol is used to help prevent recurrent attacks of hereditary angioedema, an inherited condition that can cause episodic swelling of areas such as the skin, abdomen, hands, feet, face, or airway.

4. Hormonal Suppression in Endometriosis

By suppressing ovarian hormonal activity, Danazol can reduce the hormonal stimulation associated with endometriosis symptoms.
