Key takeaways
Dextroamphetamine (Dexedrine) and Adderall (dextroamphetamine/amphetamine salts) are both stimulant medications used to treat ADHD and narcolepsy. The main difference between the two is their composition. Dextroamphetamine is a single-ingredient medication, while Adderall contains a mixture of dextroamphetamine and amphetamine salts. Both medications can cause similar side effects, such as trouble sleeping and loss of appetite. Dextroamphetamine is available in immediate-release tablets, extended-release capsules, and a liquid solution, whereas Adderall is available as an immediate-release tablet and an extended-release capsule. Both medications have a risk of misuse and dependence, so it's important to take them exactly as prescribed. If you have heart problems or a history of substance use disorder, talk to your healthcare provider before starting either medication.
