It is commonly used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. The medication works by increasing the levels of certain chemicals in the brain that help with attention and focus. Adderall is typically prescribed to improve attention span, focus, and control behavior in people with ADHD. It is also used to help with the sleep disorder narcolepsy to help maintain wakefulness.
