Adderall XR is a prescription extended-release capsule containing a combination of amphetamine and dextroamphetamine, used to treat attention-deficit/hyperactivity disorder (ADHD) in patients aged 6 and older.
It belongs to a class of drugs called central nervous system (CNS) stimulants. The "XR" stands for extended-release, which means the medication is designed to release its active ingredients gradually throughout the day, so you only need to take it once in the morning.
Adderall XR is FDA-approved for one indication:
