Adderall is a prescription medication that contains two active ingredients: amphetamine and dextroamphetamine. It belongs to a class of drugs known as stimulants, and it is primarily used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. The primary effects of Adderall involve increasing the levels of certain neurotransmitters, such as dopamine and norepinephrine, in the brain. This can lead to improved focus, attention, and impulse control in individuals with ADHD. For those with narcolepsy, Adderall can help reduce excessive daytime sleepiness.
