I investigated medication for children with ADD/ADHD on the internet.  Most sites were talking about a new medication that was just recently out called Concerta.  The FDA just decided to approve this medication for these types of disorders. One of the reasons it was developed was to get rid of the stigma some students felt when they needed to go to the office to receive their meds, just like Joey Pigza!
This new medication comes in 18 and 36 ml. tablets.  And the reports have all come back very good.  Another promising thing for ADD/ADHD.  Other sites discussed the most common medication, Ridalin, and even in some cases, Adderol.
