Short answer
Both are stimulant medications used for ADHD when clinically appropriate. Adderall (mixed amphetamine salts) has multiple formulations with varied onset/duration; Vyvanse (lisdexamfetamine) is a prodrug with smoother onset for many patients. Only a licensed prescriber should choose based on history, comorbidities, and response.
| Adderall (mixed salts) | Vyvanse (lisdexamfetamine) | |
|---|---|---|
| Form | IR & XR | Prodrug — activated in body |
| Duration | Shorter IR; XR ~hours | Often longer daytime coverage |
| Prescribing | Clinician choice—history & comorbidities | Not interchangeable DIY |
Detailed answer
Side effects, cardiovascular risk, substance-use history, and sleep impact all influence selection.
