I myself have taken Strattera for my ADHD back in 2004, I took it why attending Nursing school, and was eventually increased to the maximum dosage of 100mg. It did NOT help me at all. It's a non-stimulant inhibitor, so it works differently from Adderall, Ritilan etc... It's not for everyone. My Dr. herself takes it and says it's wonderful for her. But for me, it did nothing, I still drove my best friends nuts in school cause I couldn't sit still and concentrate! I've never taken the other two drugs, I have other ways of coping with the ADHD in everyday life. I'm about to start school again in Spring, so will be looking for something else to use so I can focus better etc... I think if your daughter's Dr reccomends it for her, it's worth a try. If it doesn't work, you can try other things. I wish my parents had me diagnosed as a child, it would of helped me so much! I wasn't diagnosed till I was an adult. Anyhow, good luck, and best wishes for your daughter!
