My son is on 40 mg of Strattera with 10 mg of Ritalin/day. When school starts he will either add a second dose of Ritalin or use a low dose of Concerta with the Strattera. He's never been on Adderall, that's why he isn't using Adderall with the Strattera. As the other person said, the Strattera seems to eliminate the rebound effect when the Ritalin wears off. Also, the Strattera helps my son's eating, sleeping, and anxiety. And once the Ritalin wears off, he's fine just having the Strattera still in him. The Strattera doesn't seem to help his focusing; that's why he also takes the stimulant.
