Key takeaways
Adderall XR (dextroamphetamine/amphetamine salts extended release) and Adderall (dextroamphetamine/amphetamine salts) are both stimulant medications used to treat ADHD, but they have some key differences. Adderall XR is an extended-release form that you take once a day, and its effects can last up to 12 hours. In contrast, Adderall is an immediate-release form that you might need to take multiple times a day, with each dose lasting about 4 to 6 hours. Adderall XR is not recommended for children under 6 years old, whereas Adderall can be used in children as young as 3 years old. Both medications can cause side effects like trouble sleeping and loss of appetite. Always talk to your healthcare provider to see which option is best for you.
