Adderall is a prescription medication that contains a combination of amphetamine and dextroamphetamine. It belongs to a class of drugs called stimulants, and it is primarily used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy.

Adderall works by affecting certain chemicals in the brain that contribute to hyperactivity and impulse control. It helps to increase attention span, reduce impulsiveness, and improve cognitive function in individuals with ADHD. The medication is available in both immediate-release (IR) and extended-release (XR) formulations.
