If it’s your first time talking with your doctor about something, then you’re not going to be prescribed anything that has the potential for abuse (ie: adderall, xanax, etc). The only thing you’ll be written for on the spot are things like SSRI’s and other meds that take weeks or months to even begin working.
A lot of doctors send their patients to GP’s or Psychiatrists in order to even be prescribed certain drugs in the first place.
Xanax is an anti-anxiety drug, not an anti-depressant. Where did you hear that from? That’s insane for any doctor or GP to prescribe something powerful like xanax, especially off-label, to a young kid.
