Efavirinz induced gynecomastia: a case report

Gynecomastia is swelling of the breast tissue in men, caused by an imbalance of the hormones, estrogen and testosterone. Drugs commonly implicated are spironolactone, cimetidine, ketoconazole, hGH, estrogens, hCG, anti-androgens, GnRH analogues and 5-α reductase inhibitors. Medications probably associated with gynecomastia include risperidone, verapamil, nifedipine, omeprazole, alkylating agents, HIV medications (efavirenz), anabolic steroids, alcohol and opioids. HIV infected patients who are treated with highly active antiretroviral therapy (HAART) can develop breast enlargement due to benign and malignant mammary diseases. We report here a case of gynecomastia due to efavirinz.
