Amphetamine toxicity: experience with 127 cases.

We present a retrospective study of 127 cases of amphetamine toxicity in an emergency department (ED). The most common presenting symptoms seen were agitation, hallucinations, suicidal behavior, and chest pain. Toxicologic analysis showed amphetamines are generally not mixed with other stimulants. The vast majority of patients did not require pharmacologic treatment in the ED. Thirteen patients (10%) required admission to the hospital. Toxic medical effects of amphetamine-related compounds seen in our patients are discussed.
