Of the antidepressants used to treat ADD, Strattera, Wellbutrin, and Norpramin are the most commonly used. Strattera is the newest of this group and has achieved much popularity, though it often has the uncomfortable side effects of nausea and fatigue. Although they are completely different substances, chemically, than the stimulants, they often have a similar effect upon the target symptoms of ADD. Sometimes, when a stimulant does not work, this group will, and vice versa.
