Source & what this means

Figures are from the CMS Medicare Part D Spending by Drug dataset (data year 2023, US public domain). "Total spending" is the gross drug cost — Medicare, plan and beneficiary payments combined — for Part D claims; it is not a list price, a negotiated price, or what any individual pays. Spending per dosage unit is volume-weighted across formulations. This is general public-spending information, not medical or pricing advice. Your own cost depends on your plan, deductible and coverage phase — verify with your Part D plan and a pharmacist. Data as of June 2026. See our methodology and disclaimer.
