> The treatment for ADD is one of two medications, methylphenidate or dexamphetamine. You can try other things in addition to these, but not instead of these, and you should try both - there really is just no substitute.

No, not quite - there's a variety of different ADHD medications and I'd argue there's more popular ones like Vyvanse (lisdexamfetamine). Non-stimulants like Strattera or Intuniv absolutely can and are prescribed on their own, which are really useful for people that respond poorly to stimulants.

Perhaps you meant to say there's two main classes of stimulants (amphetamines, methylphenidates) that are worth investigating and shouldn't be skipped over?

Vyvanse is dexamphetamine. I suppose you can say “amphetamines” instead, I imagine the subtleties of the terminology differ quite a bit in different places.

Strattera can help (I mentioned bupropion, another SDNRI). Of course if you try stimulants and don’t respond well, it’s totally fine to just use e.g. Strattera. What I’m advocating against is e.g. “try Strattera first, if it seems to help, don’t bother with stimulants”. (Some places, cultures, or medical systems do have surprisingly strong biases against stimulants!)
