This article does a good job of discussing some of the medications commonly prescribed for ADD. Medications covered are Adderall, Catapres, Cylert, Dexedrine, Dextrostat and Ritalin. Side effects, usage while pregnant or breastfeeding, contraindications, etc are all discussed here in fairly good detail.

I'm not sure what it is about this site, but I just don't feel very confident about it. I'm pretty sure the information is good, but I'm hoping there are sites that go into more depth.
