Adderall is a prescription medication that combines two central nervous system stimulants: amphetamine and dextroamphetamine. It is commonly prescribed to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. Adderall works by increasing the levels of certain neurotransmitters in the brain, such as dopamine and norepinephrine, which play a role in regulating attention, focus, and impulse control.

Adderall is available in immediate-release (IR) and extended-release (XR) formulations. The immediate-release version typically lasts for about four to six hours, while the extended-release version provides effects for up to 12 hours. The specific dosage and formulation prescribed depend on the individual's needs and response to the medication.

It's important to note that Adderall is a controlled substance due to its potential for misuse, addiction, and dependence. It should only be used under the guidance and supervision of a healthcare professional and taken exactly as prescribed. Regular monitoring by a doctor is important to ensure its effectiveness and to manage any potential side effects.
