The National Institute of Mental Health (NIMH) has a concise entry on Attention Deficit and Hyperactivity Disorder in Adults.

Medication Management for Adults with AD/HD – 16 pages, published March 2004 by The National Resource Center for AD/HD (a program of CHADD).

Why didn’t my doctors give me this paper on our very first meeting?

It would have answered half the questions I tried to get answered
during our too-brief sessions, and a lot of questions I never got to
ask like, “has anyone taken a good look at how these meds will affect
my cardiovascular health?” and “can you tell me again why Adderall
might be better for me than Prozac (or vice versa)?”

I like how this piece is both readable and technically
comprehensive.  Among the contents: comparisons of different meds,
dosing considerations and effects, side effects, and cautions on
addiction risk.

Excerpt:

“This information and resource sheet will:

• provide a basic understanding of how stimulants can be used safely and effectively to treat AD/HD in adults.
• discuss nonstimulant medications for AD/HD in adults, including
  those approved by the Food and Drug Administration for the treatment of
  AD/HD in adults
• discuss the effect of coexisting psychiatric disorders on the medical treatment of adults with AD/HD.”
