Adderall is a prescription medication that contains a combination of amphetamine and dextroamphetamine salts. It is primarily prescribed to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy.

Adderall belongs to the class of drugs known as stimulants. It works by increasing the levels of certain chemicals in the brain, including dopamine and norepinephrine, which play a role in regulating attention, focus, and impulse control.

The medication is available in immediate-release and extended-release formulations. Immediate-release Adderall typically lasts for about 4 to 6 hours, while the extended-release version can last up to 12 hours. The dosage and dosing schedule are determined by a healthcare professional based on the individual's needs and response to the medication.

Adderall should only be used under the supervision of a healthcare professional, as it carries the risk of misuse, abuse, and dependence. It is a Schedule II controlled substance in the United States due to its high potential for abuse.
