The answer is E, all of the above. Stimulants are typically first-line treatment for ADHD. However atomoxetine, a selective noradrenergic reuptake inhibitor; buproprion, an antidepressant; and clonidine or guanfacine, alpha-2 agonists should be considered in those who cannot tolerate stimulants or in cases where stimulants are contraindicated.
