Description and Brand Names | Before Using | Proper Use | Precautions | Side Effects

  • Stimulant, central nervous system - Amphetamine; Dextroamphetamine; Methamphetamine

Amphetamines (am-FET-a-meens) belong to the group of medicines called central nervous system (CNS) stimulants. They are used to treat attention-deficit hyperactivity disorder (ADHD). Amphetamines increase attention and decrease restlessness in patients who are overactive, unable to concentrate for very long or are easily distracted, and have unstable emotions. These medicines are used as part of a total treatment program that also includes social, educational, and psychological treatment.

Amphetamine and dextroamphetamine are also used in the treatment of narcolepsy (uncontrollable desire for sleep or sudden attacks of deep sleep).

Amphetamines should not be used for weight loss or weight control or to combat unusual tiredness or weakness or replace rest. When used for these purposes, they may be dangerous to your health.
