Adderall is a prescription medication that contains a combination of amphetamine and dextroamphetamine. It is primarily used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. Adderall works by increasing the levels of certain neurotransmitters in the brain, which helps improve focus, attention, and impulse control. Adderall is commonly prescribed for ADHD and is also used to treat narcolepsy, a sleep disorder that causes excessive daytime sleepiness. Adderall works by stimulating the central nervous system (CNS), enhancing the activity of neurotransmitters like dopamine and norepinephrine.
