Adderall XR

Adderall XR is a CNS stimulant made from a mixture of dextroamphetamine and amphetamine salts, taken once daily as an extended-release capsule. It's FDA-approved for ADHD in both adults and children 6 and older, but it has no other FDA-approved uses beyond ADHD.

Vyvanse vs. Adderall XR Indications

Vyvanse

Vyvanse treats ADHD in children, teens, and adults, and it's the only stimulant specifically approved for binge eating disorder. It won't work for weight loss on its own, even though appetite suppression is a side effect.

  • ADHD in patients 6 years and older

  • Moderate to severe binge eating disorder in adults

  • Not approved for weight loss or obesity treatment

Adderall XR

Adderall XR treats ADHD across the same age range as Vyvanse, from children 6 and up through adulthood, but it does not carry any other FDA-approved indications. It's not approved for weight loss, binge eating, or any use beyond ADHD.

  • ADHD in adults and children 6 years and older

  • Not approved for children under 6

  • Not approved for patients with end-stage renal disease

Vyvanse vs. Adderall XR Pros and Cons

Vyvanse

Vyvanse's prodrug design means it must be converted in the body before becoming active, which may make it harder to misuse by snorting or injecting. It's also the only stimulant FDA-approved for binge eating disorder, a use case Adderall XR doesn't cover, but it typically costs more out of pocket.

Pros

  • FDA-approved for binge eating disorder, unlike Adderall XR

  • Prodrug design may lower misuse potential via snorting or injecting

  • Available as a chewable tablet for those who dislike capsules

Cons

  • Typically costs more, roughly $380 to $462 per month before insurance

  • Takes longer to kick in since it must be converted to its active form

  • Only comes as a single fixed once-daily dose, less flexible titration

Adderall XR

Adderall XR contains active amphetamine salts directly, so it starts working faster but may carry more misuse risk through non-oral routes than a prodrug. It has a longer track record across the full ADHD age range since 2001, and it typically costs less than Vyvanse.

Pros

  • Typically costs less, roughly $200 to $350 per month before insurance

  • Faster onset of action since it doesn't require enzymatic conversion

  • Longer market history across children, teens, and adults since 2001

Cons

  • No FDA-approved use for binge eating disorder

  • Higher potential for misuse via non-oral routes since it's not a prodrug

  • More gastrointestinal side effects reported, like abdominal pain and vomiting
