Strattera - Why are so many doctors against it?

My doctor is on the preferred providers list and I trust him. He’s a good, solid, responsible family practitioner who has a large, healthy practice. My brother was diagnosed and treated for 2 years with Strattera by a psychiatrist who specialized in ADHD and was referred back to our family doctor after the firm diagnosis and medication stabilization process. Our doctor was against Strattera. Why are so many doctors against Strattera?

I guess that so many doctors are against Strattera because there are too many reports of the possibility that there may be long-term issues that haven’t been studied long enough. We have tried generic medications, cheaper medications, Ritalin does not work and kills his appetite and Concerta isn’t even on the “prior authorization” list — it’s denied outright. So, in the end we switched to Adderall in the hopes of getting some sort of co-coverage.
