Danazol — Uses, Dosage, Side Effects & Safety

Drug class: Androgen; Antigonadotropin

Overview

Danazol is a synthetic hormone used to treat a variety of conditions related to hormone imbalances, such as endometriosis, fibrocystic breast disease, and hereditary angioedema. It works by decreasing the amount of certain hormones in the body, which helps reduce symptoms like pain, swelling, and abnormal tissue growth. Danazol acts by suppressing the pituitary gland's release of hormones that stimulate the ovaries and testes. This leads to a reduction in estrogen and progesterone levels, making it effective for hormone-sensitive conditions. Patients should know that Danazol can cause side effects related to its androgenic (male hormone-like) activity, such as weight gain, acne, and changes in menstrual cycles. It is important to use Danazol exactly as prescribed and to attend regular follow-up appointments to monitor for side effects and effectiveness.
