What are amphetamines?

Amphetamines are stimulant drugs that speed up how your body functions. Healthcare providers may prescribe amphetamines to people with ADHD or narcolepsy. Providers may also use amphetamines to treat obesity, though this is less common.

How do amphetamines work?

Neurotransmitters send messages between cells in your body to tell the cells how to do their job. Amphetamines make your central nervous system (the hard drive to your brain and spinal cord) work faster by increasing the number of neurotransmitters, specifically:

• Dopamine.
• Norepinephrine.
• Serotonin.

When you take an amphetamine, neurotransmitters put your cells on speed dial to send messages quickly. This causes people to feel:

• Alert.
• Attentive.
• Calm.
• Energetic.
• Focused.
• Happy (joy or euphoria).

Are amphetamines a stimulant?

Yes, amphetamines are a stimulant. Stimulants increase the activity of your central nervous system or the part of your brain that sends messages to nerves to tell them how to complete their jobs.

What are the brand names of amphetamines?

Common brand names for amphetamines include:

• Adderall®.
• Concerta®.
• Dexedrine®.
• Focalin®.

• Vyvanse ®.

What are amphetamines approved for?

The U.S. Food and Drug Administration approved certain amphetamines to manage and treat ADHD, obesity and narcolepsy, specifically dextroamphetamine and levoamphetamine.

Can amphetamines treat ADHD in children?

Yes, your healthcare provider might offer low-dose amphetamines to treat attention deficit hyperactivity disorder (ADHD) in your child, like Adderall ® or Ritalin ®. Amphetamines create a calming effect for children diagnosed with ADHD by targeting the chemicals in their brain that transmit signals between nerves in the central nervous system.

Amphetamines have shown improvement in children diagnosed with ADHD by:

• Decreasing impulsive behavior.
• Improving attention span.
• Improving focus.
• Improving task completion.
• Lessening hyperactive symptoms.
• Reducing fidgeting.

There is no evidence that amphetamines given to children diagnosed with ADHD cause addiction or drug abuse, but there is a potential for addiction or abuse if the person taking the stimulant has a history of substance abuse. Research shows that people with ADHD had a lower rate of substance use disorder if they were medically treated versus not receiving treatment.

If you experience withdrawal symptoms while you’re following your prescribed schedule, talk with your healthcare provider.

What’s known about amphetamines and overdose?
