​Adderall XR 30 mg is a prescription medication used to treat ADHD (Attention Deficit Hyperactivity Disorder). The “XR” stands for Extended Release, which means the medicine is released slowly over time, usually lasting up to 12 hours with just one dose in the morning. The “30 mg” refers to the amount of medicine in each capsule. Adderall XR contains a mix of two stimulant medications: amphetamine and dextroamphetamine. These help improve focus, attention, and impulse control.
