Both are CNS stimulant • Side-by-side comparison
Adderall vs Vyvanse: Overview
Adderall and Vyvanse are both central nervous system stimulants prescribed for ADHD (Attention-Deficit/Hyperactivity Disorder) and are among the most commonly prescribed medications for this condition. Adderall contains a mixture of amphetamine salts (75% dextroamphetamine and 25% levoamphetamine) and is available in both immediate-release (IR) and extended-release (XR) formulations. Vyvanse contains lisdexamfetamine, a prodrug that is converted to dextroamphetamine in the body, providing a smoother onset and longer duration of action lasting up to 14 hours. Vyvanse is also FDA-approved for binge eating disorder in adults, making it unique among ADHD stimulants. While both are Schedule II controlled substances, Vyvanse carries a lower potential for abuse due to its prodrug mechanism — it must be metabolized before becoming active.

Key Differences
Which Should You Choose?
For most adults seeking all-day coverage with smoother onset and offset, Vyvanse is often preferred. For children or patients who need flexible dosing or shorter duration, Adderall IR offers more control. Cost is a major factor — generic Adderall is significantly cheaper than brand-name Vyvanse, though Vyvanse generics are now available. Your doctor will consider your specific ADHD symptom pattern, lifestyle, and history of substance use when choosing between these medications.
