What is the difference between Adderall XR and Adderall?

Adderall XR and Adderall contain the same ingredients that treat attention deficit hyperactivity disorder (ADHD), but the dosing is different. Adderall XR is an extended-release capsule taken in the morning that contains a whole day’s worth of medication, whereas Adderall is a tablet that may be taken two to three times every day. Talking to your doctor will help you decide which form of Adderall is better fit for you.
