The clinical considerations differed depending on the medication. I picked up a clearer copy of the report from our doctor's office today. Even the medication he takes, Guanfacine, has a clinical consideration 4 (see below) but it has worked pretty well for him in the past. The only medication that lists a risk of more side effects is Strattera. If I'm putting much faith in this report, Adderall, Dexedrine, or Vyvanse may be worth at least a try at a low dose. I've also done some reading today and there is one study that lends some support to the strategy of using Guanfacine along with a stimulant.

Clinical Considerations:
1. Serum level may be too high, lower dose may be required.
3. Genotype is associated with reduced therapeutic response to this drug.
4. Genotype suggests a reduced response to this medication.
5. Genotype indicated patient may experience increased side effects, but also increased efficacy.

Adderal: 1,3
Dexedrine: 1,3
Vyvanse: 1,3
Kapvay: 1,4
Strattera: 1,5
Focalin: 3,4
Ritalin, Concerta: 3,4
