the public record, side by side

buspirone vs hydroxyzine

BuSpar and Vistaril / Atarax, 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 →

buspirone (BuSpar)

non-benzodiazepine anxiolytic

FDA approval
1986 · full approval journey →
Who takes it (US, 2024)
3,719,958 patients · 16,706,971 prescriptions (ClinCalc/MEPS)2014 → 2024: up 121% (7,560,250 → 16,706,971 prescriptions)
Who pays (2024)
Medicare: 7,844,181 claims · 1,553,798 beneficiariesMedicaid: ≥5,245,157 prescriptionsCommercial claims: not published in any public dataset — a real absence, not a zero.
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 →10,969 all-time reports; most-reported terms: fatigue, nausea, headache

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.
