Is amphetamine or lisdexamfetamine better?

No honest page can answer that in one line. Head-to-head differences between comparable psychiatric medications are usually smaller than rankings suggest, and which fits you depends on your history, other medications, and side-effect trade-offs. What CAN be compared is the public record — usage, payers, label warnings, approval history, litigation — which is what this page does, with sources.

Which is prescribed more, amphetamine or lisdexamfetamine?

The page shows the latest federal survey estimates (ClinCalc DrugStats from MEPS) for both — patients and prescriptions per year, with the ten-year trend. Prescription volume reflects habits, prices, and marketing as much as evidence, so it is context, not a verdict.

the public record, side by side

amphetamine vs lisdexamfetamine

Adderall and Vyvanse, compared on what the public record actually supports: who takes each one, who pays, what the labels warn, and what the litigation record holds. Sources on every number.

What this page will not do is rank them. These drugs are in different classes and were tested for partly different things, so a single-axis ranking would be a category error. Which one fits you turns on your history, your other medications, and side-effect trade-offs — a prescriber conversation. This page arms that conversation; here are the questions worth taking into it →

amphetamine (Adderall)

stimulant (ADHD)

FDA approval: year not stated in our verified record · full approval journey →
Who takes it (US, —): no survey estimate in our record
Who pays (2024): no public payer series in our record
Boxed warning: None on the current FDA label in our record.
Adverse-event reports (FAERS): Caveat first: FAERS counts unverified REPORTS, not patients or rates — no denominator, and attention inflates reporting. Never compare these counts head-to-head; a longer-marketed, more-prescribed drug accumulates more reports by exposure alone. how to read FAERS →not in our record
Legal & safety record: no dedicated record page yet; the journey page carries label history

Where these numbers come from

Patients and prescriptions: ClinCalc DrugStats (federal MEPS survey), latest published year — counts of people filling prescriptions, not outcomes.
Medicare/Medicaid: CMS public datasets; commercial insurance publishes no per-drug series, so it renders as an absence, never a synthesized number.
Label facts: the drugs' current FDA labels via DailyMed — quoted in context on each drug's approval-journey page.
FAERS: openFDA — reports, never rates; the caveat travels above every count.
Litigation: court records and regulator documents only, on the linked record pages; settled is never adjudicated.
