Drug Information
7 reviews for Danazol
Danazol is a hormone medicine used for endometriosis, some painful breast conditions, and hereditary angioedema (repeated attacks of swelling).
It is used less often today because of its side effects.
What is it used for?
- Endometriosis
- Fibrocystic breast disease (painful, lumpy breasts)
- Preventing attacks of hereditary angioedema
How does it work?
Danazol lowers the hormones that stimulate the ovaries, which reduces oestrogen and shrinks endometriosis tissue. It also raises a protein that prevents swelling attacks in hereditary angioedema.
