I took Spironolactone for months for Acne treatment. It worked my skin looked great and I did not notice that reduction in facial hair until I read your post. Now I remember I really did have a reduction. However, I gained about 30 pounds. I gained weight like crazy while taking Spironolactone. I work out several times a week and actually try to work out daily so lack of exercise was nto the issue. I have always ate pretty healthy and very much into eating right. When I got off the Spironolactone I loss most of the weight and the hair and Acne returned.....Have you heard of harmones causing weightgain?
