I am a 26 year old white male, and when I was 10, I was put on a drug called Concerta to treat A.D.D. I was on the drug for 2 years, and after coming off of it, I noticed i had developed a minor to moderate case of Gynocomastia. Even after diet and exercise, and doing natural bodybuilding, the problem has never gone away, and has scarred me mentally to this day. I have heard other reports of the same thing involving the use of Concerta. Could this drug be the culprit? If so could the company who made Concerta be looking at some lawsuits?
Dear patient Concert contains methylphenidate which is prescribed for ADHD and has known side effect of gynecomastia.  This is benign non-cancerous enlargement of male breast. Best way to get rid of this condition is surgical reduction of breast size. Medication are not found effective in reducing gynecomastia. You need to consult expert surgeon nearby area and get yourself examined and opined.  All the best.
