What are common side effects of Danazol?

Danazol is a synthetic steroid that is primarily used to treat endometriosis and certain types of breast disease. Its mechanisms mimic testosterone, leading to a variety of hormonal side effects. Common side effects associated with Danazol include edema (fluid retention), hirsutism (excess hair growth), hair loss, and vocal changes (voice deepening or hoarseness).

These side effects stem from Danazol's androgenic effects, which can alter hair follicle sensitivity and affect fluid balance in the body, contributing to edema. Additionally, Danazol can stimulate hair growth in androgen-sensitive areas while causing thinning of hair on the scalp. Changes in voice can occur due to the drug's action on vocal cord structure and function.

Other options list side effects but do not encompass the most characteristic effects associated with Danazol. While gastrointestinal upset, dizziness, fatigue, skin rash, fever, and headache can be side effects of various medications, they are not typically associated with Danazol usage in the same prevalent manner as the side effects mentioned in the correct choice. The focus on the specific hormonal and androgenic effects is what makes the second option the most accurate representation of Danazol's common side effects.
