Adderall is a prescription medication combining amphetamine and dextroamphetamine, commonly used to treat Attention Deficit Hyperactivity Disorder (ADHD) and narcolepsy. It helps improve concentration, alertness, and impulse control by balancing key brain chemicals. Available in both immediate-release (IR) and extended-release (XR) forms, Adderall should only be taken under a doctor’s supervision due to possible side effects and risk of dependence.
