Adderall is the brand name for a prescription medication containing a combination of amphetamine and dextroamphetamine salts. Adderall 10 mg is classified as a central nervous system (CNS) stimulant and is most commonly prescribed for the treatment of attention-deficit/hyperactivity disorder (ADHD) and narcolepsy. Adderall 30 mg dosage represents one of the higher-strength formulations available, and it is typically prescribed to patients who require a substantial therapeutic effect, either due to the severity of their symptoms or after titration from lower doses.
