Adderall 20 mg is a prescription stimulant medication containing mixed amphetamine salts. It is commonly used to treat Attention Deficit Hyperactivity Disorder (ADHD) and narcolepsy by increasing the levels of dopamine and norepinephrine in the brain, which helps improve focus, attention, and impulse control. This dosage is typically part of a broader treatment plan including psychological, educational, and social components. Due to its potential for abuse and dependence, Adderall should be taken exactly as prescribed by a healthcare professional.
