Adderall XR 30 mg is a prescription medication primarily used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. It's a combination of two stimulant drugs, amphetamine and dextroamphetamine, which work by increasing the levels of certain chemicals in the brain that contribute to impulse control and hyperactivity. When used as prescribed, Adderall can help improve focus, attention, and impulse control in individuals with ADHD, and it can also help manage symptoms of narcolepsy, such as excessive daytime sleepiness and sudden episodes of sleep.
