How Does Adderall Work?

Adderall is a stimulant, which means it stimulates activity of the central nervous system (CNS). Specifically, experts believe it works primarily by inhibiting the reuptake, or reabsorption, of the neurotransmitters norepinephrine, dopamine, and serotonin.

These neurotransmitters, or chemical messengers, have important functions, all of which may improve the symptoms of both ADHD and narcolepsy. For instance, norepinephrine (noradrenaline) can heighten alertness and focus. Dopamine is strongly involved with the capacity to think critically and plan. Serotonin, often called the “feel-good neurotransmitter,” impacts mood as well as learning, memory recall, and cognition.

How quickly this medication begins to work varies based on several factors, including the individual patient taking it and dosage. That said, someone taking an immediate-release formulation would likely begin to feel Adderall’s effects within an hour.
