Key takeaways
Dextroamphetamine (Dexedrine Spansule, ProCentra, Zenzedi) and Adderall XR (dextroamphetamine/amphetamine salts extended release) are both stimulant medications used to treat attention deficit-hyperactivity disorder (ADHD). They also share the off-label use of treating narcolepsy. However, they differ in several ways. Dextroamphetamine is a single-ingredient medication available in immediate-release tablets, extended-release capsules, and a liquid solution, while Adderall XR is a combination of dextroamphetamine and amphetamine salts available only in extended-release capsules. Dextroamphetamine can be used in children as young as 3 years old, whereas Adderall XR is typically used for children 6 years and older. Both medications have a risk of misuse and dependency, but Adderall XR is often considered a first-choice medication for ADHD. Common side effects for both include trouble sleeping and loss of appetite, headaches, and nervousness. Both medications can interact with other drugs, especially those affecting serotonin levels, and should not be taken with monoamine oxidase inhibitors (MAOIs).
