Adderall is a prescription medication that combines two stimulant drugs, amphetamine and dextroamphetamine. It is primarily used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. By increasing the levels of certain neurotransmitters like dopamine and norepinephrine in the brain, Adderall helps improve focus, attention span, and impulse control in individuals with ADHD. It comes in immediate-release and extended-release (Adderall XR) forms and is typically taken once or twice a day under medical supervision.
