Hi Dr.Rassman, what are your opinions regarding the safety and effectiveness of topical spironolactone? Is it a safe alternative to proprecia or does it pose harmful side effects?
It does work for the treatment of balding, but the side effects are significant and far more common than Propecia, including the scope of side effects.
Spironolactone causes an increased risk of bleeding from the stomach and duodenum, gynecomastia, and testicular atrophy (kills off the testicles or makes them smaller and less effective). Erectile dysfunction would be common and it can cause a serious rise in potassium in the body (hyperkalemia). The side effects and complications go on and on.
It should never be used to treat the benign condition of male pattern hair loss.
