How they work
Adderall is a mix of four amphetamine salts. It raises the levels of dopamine and norepinephrine in the brain, which improves focus and impulse control. Vyvanse contains lisdexamfetamine, an inactive prodrug that the body slowly converts to active dextroamphetamine. Because of this activation step, Vyvanse releases more gradually.
Many people describe Vyvanse as "smoother" — less of a sudden peak and less of an evening crash — while Adderall tends to act faster and wear off sooner.
Which lasts longer?
Vyvanse typically lasts 10–14 hours, which makes it a common choice when a single daily dose needs to cover the whole school or work day. Standard (immediate-release) Adderall lasts about 4–6 hours and is often taken twice a day. Extended-release Adderall XR lasts 10–12 hours.
Side effects to be aware of
Both medications share similar side effects, including reduced appetite, dry mouth, trouble sleeping, headache and a slightly raised heart rate. With Adderall the effects can feel more pronounced, especially around the "peak." Vyvanse's slower release often translates to a gentler side-effect profile, though you may still notice appetite suppression late into the day.
Neither medication should be used without a doctor's guidance, and both are Schedule II controlled substances in the United States.
Cost and generic availability
Generic amphetamine salts (the same active drugs as Adderall) are widely available and usually the least expensive option. The generic for Vyvanse, lisdexamfetamine, is also available and costs less than the brand. Price varies with your insurance, pharmacy and country, so compare with your usual provider.
How to choose
There is no single "best" ADHD medication — the right choice depends on how long you need coverage, how your body reacts, whether you have struggled with substance use, and cost. A clinician uses your history and symptoms to decide, and sometimes people try both before settling on one.
Always discuss dosing, interactions and monitoring with a licensed healthcare provider before starting or changing any stimulant.
Frequently asked questions

Not necessarily — they use different active ingredients with different release patterns. Adderall peaks faster; Vyvanse lasts longer. "Strength" is individual and depends on dose and how your body processes each drug.

Switching is common but should only be done with your doctor, who will calculate an equivalent dose and monitor you.
