The FDA specifically on-label approved ritalin for kids, hormone replacement therapy, and statins for people with high cholesterol but no signs of heart disease. Your faith in regulation is misplaced. If you take FDA approval and a doctor's recommendation as proof a prescription is safe you are misguided. (The AMA is a lobbying organization to which about 15% of doctors belong and is irrelevant here.)

There is no reliable government organization out there stopping harmful medical treatments. I just want to acknowledge that as fact rather than pretend otherwise and deny people choices.
