Although many people are recommended to take medication for Attention Deficit Hyperactivity Disorder (ADHD), or Attention Deficit Disorder (ADD), the costs of the medication can be too high for some people to take advantage of their benefits.
I found a resource online which shows you the US costs for all of the ADHD medication.
In general, the older ADHD medications are much cheaper. These include: Ritalin, Ritalin SR, Dexedrine, Dexedrine Spansule, and any medication which is old enough to be a generic ADHD medication.
You can find the chart listing the costs of ADHD medication here. This chart is updated as of November 2006.
At the time of writing this report, Vyvanse is not yet released, and thus its cost is not listed.
I have taken some images of the chart, just to preview it for you here:
