Adderall is a prescription medication that contains two active ingredients: amphetamine and dextroamphetamine. It belongs to a class of drugs called central nervous system stimulants. Adderall is primarily used in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy. Adderall is commonly prescribed to individuals with ADHD to help improve focus, attention, and impulse control. It works by increasing the levels of certain neurotransmitters, such as dopamine and norepinephrine, in the brain. Adderall may also be prescribed to individuals with narcolepsy, a sleep disorder characterized by excessive daytime sleepiness and sudden episodes of sleep.
