How Does Adderall XR Work?
Adderall XR is a stimulant, although it has effects that are opposite from what would be expected of a stimulant. While stimulants (like caffeine) can cause hyperactivity, Adderall XR can have a calming effect. While the exact way Adderall XR produces a calming effect is not known, it is known that Adderall XR affects chemicals in the brain.
Adderall XR is a medication that is designed to dissolve slowly. Because the medication is released slowly, it can be taken just once a day, eliminating the need to take medication at school or work.
