Adderall XR Dosing

The Adderall XR dosing guidelines for people with ADHD will vary depending on several factors, such as age, other medical conditions they may have, and other medications they may currently be taking. It is recommended that you start on a lower dosage of Adderall XR, with the dosage being increased slowly and only if necessary. Adderall XR is designed to be taken in the morning; if it is taken later in the day, it can cause problems sleeping.
