Adderall is a prescription stimulant commonly used to treat ADHD (Attention Deficit Hyperactivity Disorder) and narcolepsy. It improves concentration, attention span, and impulse control by increasing levels of dopamine and norepinephrine in the brain. Adderall is available in immediate-release (IR) and extended-release (XR) forms, making it suitable for short-term or all-day symptom management.
