My then 8 year old was on the Strattera, it wasn't worth the side effects for us, but remember that everyone's system handles meds differently.
It takes a MONTH to work correctly, and it made an already anxious little boy TERRIFIED of things that were minor annoyances before. He was sure that our car was going to fly off the side of a parking deck and we were going to die when we parked above ground level. He cried out of terror in the elevator to get to the doctors office (normally he tells me which button to push and jumps up on the little railing to sit while we go up.) I had to half carry him off the elevator.
For the positives, um...? It might have made school work a little easier if he wasn't terrified that the school bell for lunch might be 20 seconds late and that he would miss eating and die of starvation...
It takes a MONTH to get in your system, but the nurse told me it would take 2 days to get it out. SOOOO, don't miss 2 doses in a row...

I think my cousin (early 20s) was also on this, it worked well for him but I think it made his nose bleed so they tried something else. (lots of things make his nose bleed though, it seems.)
