Adderall is a prescription suggested for treating attention deficit hyperactivity disorders and narcolepsy. It refers to a class of medications called stimulants. Adderall 30 mg contains amphetamine and dextroamphetamine, which are nervous system stimulants that affect brain cells that contribute to hyperactivity and impulse control. It is a standard prescription to treat attention-deficit hyperactivity disorders; therefore, it also effectively increases daytime alertness in people with narcolepsy, although there is likely related research available.
