Hello, my 6 yr boy's been diagnosed with adah-pi, treatment is with metilphenidate which's supposed being a drug, is the treatment safe for him?

Maybe: This is a common treatment for hyperactivity or focus disorders. The safety of any med depends on individual factors, dose/weight/ actual effect on the child. You should see benefit from the therapy within a few days and few or no side effects before deciding to continue.If no benefit, a different dose or med may be needed. Close followup with the doc is important.
