Medications That May Trigger Gynecomastia in Men
An article lists 10 medicines linked to gynecomastia in men, explaining how hormone balance shifts—lower testosterone, higher estrogen, or raised prolactin—can enlarge breast tissue. Drugs highlighted include spironolactone, finasteride, anabolic steroids, antipsychotics, nonsteroidal antiandrogens, diazepam, cimetidine, ketoconazole, and metronidazole. In many cases the condition resolves after stopping the drug, but it can linger and may require treatment or surgery in some men.
