Danazol: Uses, Dosage, Side Effects and More

Danazol is a synthetic hormone that belongs to a class of medications known as androgenic steroids. It is primarily used to treat various medical conditions related to hormonal imbalances, particularly in women. Danazol is effective in managing endometriosis, fibrocystic breast disease, and certain types of hereditary angioedema. By mimicking the effects of male hormones, it helps to regulate the hormonal environment in the body, providing relief from symptoms associated with these conditions.

Uses of Danazol

Danazol has several approved medical uses, including:

1. Endometriosis: Danazol is commonly prescribed to alleviate the pain and symptoms associated with endometriosis, a condition where tissue similar to the lining of the uterus grows outside it.
2. Fibrocystic Breast Disease: It helps reduce breast pain and tenderness in women suffering from fibrocystic changes in breast tissue.
3. Hereditary Angioedema: Danazol is used to prevent and treat episodes of swelling in patients with hereditary angioedema, a genetic condition that causes severe swelling in various body parts.
4. Other Conditions: It may also be used off-label for conditions like menorrhagia (heavy menstrual bleeding) and certain types of breast cancer.

How It Works

Danazol works by altering the hormonal balance in the body. It suppresses the production of certain hormones, including estrogen and progesterone, which are involved in the menstrual cycle and the growth of endometrial tissue. By reducing estrogen levels, Danazol helps to shrink endometrial tissue and alleviate symptoms. Additionally, it has anti-inflammatory properties that can further help in managing pain and swelling associated with various conditions.

Dosage and Administration

The dosage of Danazol varies based on the condition being treated:

• Endometriosis: The typical starting dose is 800 mg per day, divided into two or four doses. This may be adjusted based on response and tolerance.
• Fibrocystic Breast Disease: A common dosage is 100-400 mg per day, taken in divided doses.
• Hereditary Angioedema: The usual dose ranges from 600 to 1200 mg per day, depending on the severity of the condition.

Danazol is available in oral tablet form and should be taken with food to minimize gastrointestinal side effects. It is important to follow the prescribing physician's instructions regarding dosage and duration of treatment.
