Adderall XR
A healthcare provider may prescribe Adderall XR to help treat attention deficit hyperactivity disorder (ADHD). Although the medication is a stimulant, it can cause a calming effect when used in certain doses to treat ADHD. It comes in capsule form and is designed to dissolve slowly. Possible side effects include loss of appetite, insomnia, and weight loss.
Adderall XR® (amphetamine-dextroamphetamine extended release) is a prescription medication that is used to treat attention deficit hyperactivity disorder (ADHD). Because it is an amphetamine and is commonly abused, there are special rules for prescribing it (see Adderall: A Controlled Substance).

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 it produces a calming effect is not known, it is known that the medication 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.
There have been several studies looking at using Adderall XR for ADHD symptoms. Some of the results of these ADHD research studies are highlighted below.
