I imagine a lot of the push is from doctors or gps who are so harassed and pushed by patients/ the parents that , as with the devastating over prescription of antibiotics in the past, they succumb to the pressure.
I can’t believe that any doctor actually believes that prescribing powerful drugs that they know are very likely to damage growth, brain development, fertility, bone density, heart function and other vital physical processes to patients who are simultaneously presenting with issues such as depression, anorexia , bulimia, anxiety and autism can be a good idea and in the best interests of their patients. What happened to “first do no harm”?
