Adderall is a prescription medication primarily used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. It contains a combination of amphetamine and dextroamphetamine, both of which are central nervous system stimulants. When taken as prescribed, Adderall can help improve focus, attention span, and impulse control in individuals with ADHD. Additionally, it can help those with narcolepsy manage excessive daytime sleepiness and sudden episodes of sleep.
