Can drugs other than steroids cause gyno?
Sure. One of the questions I ask my gynecomastia patients who don’t use steroids is if they smoke marijuana. And I bet that lots of steroid users have confessed marijuana use before they’d admit to steroid use at the doctor’s office. Other prescription drugs which are associated with the condition include the anti-ulcer drug, cimetidine or “Tagamet”, and Spironolactone, which is a diuretic used for high blood pressure. Another agent that we tend to forget about is alcohol, which can affect metabolism in the liver, enhancing the effect of other drugs as well as contributing to development of gynecomastia itself.
