They are different drugs with different mechanisms of action. One notable difference from my experience is that Ritalin has a stimulant effect, whereas Strattera actually made me tired.

Had a similar experience. Was on this for a bit when I had a GP who seemed hesitant to prescribe stimulants even though I had historically taken ritalin and it was fine (all side effects were manageable).

You better search it, but I believe the difference is Ritalin is an amphetamine.

Ritalin is not a form of amphetamine. Ritalin's active ingredient is methylphenidate.

Ritalin is not "an amphetamine" but rather a psychostimulant. It's a DEA schedule II regulated drug.

Strattera works via a different mechanism and (supposedly) is likely not to be habit-forming. Ritalin definitely can be habit-forming.
