Adderall is a prescription medication that contains a combination of amphetamine and dextroamphetamine. These are stimulant medications used primarily to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. Adderall works by increasing the levels of certain neurotransmitters in the brain, namely dopamine and norepinephrine. These chemicals play a crucial role in regulating attention, focus, and impulse control. Adderall helps increase attention and decrease impulsiveness and hyperactivity in people with ADHD. It helps people with narcolepsy stay awake during the day.
