Methamphetamine

What is methamphetamine?

Methamphetamine is a stimulant and an appetite suppressant. It stimulates the central nervous system (nerves and brain) by increasing the amount of certain chemicals in your body. This increases your heart rate and blood pressure and decreases your appetite, among other effects.

Methamphetamine is used to treat attention deficit disorder with hyperactivity (ADHD).

Methamphetamine may also be used for purposes other than those listed in this medication guide.

Methamphetamine is habit forming. You can become physically and psychologically dependent on this medication, and withdrawal effects may occur if you stop taking it suddenly after several weeks of continuous use. Talk to your doctor about stopping this medication gradually.
