Just 3 companies supply this market — thin enough that a single exit would be felt immediately. The price has held steady around $0.4385 per unit over the past year. Put together: this looks like a healthy supply — the boring kind, which is exactly what you want.
The numbers behind every sentence are on this page below — and the Watch button emails you when any of them move.
Matched to CMS's representative package for this drug (NDC 00781-2145-01) — same generic, strength, and dosage form. CMS prices one NDC per drug concept, not every package.
Negotiated 30-day point-of-sale unit prices and formulary terms aggregated across every unsuppressed Part D and MA-PD plan for the quarter shown. Point of sale means gross of confidential rebates. CMS publishes one representative NDC per drug concept (RxCUI) rather than every package, so these figures come from CMS's representative package for the same drug — matched on generic name, strength, and dosage form. Estimated from MedPAC's program-wide rebate aggregates (June 2023: DIR = 29% of gross Part D spending; brand rebates ≈ 25–40% of gross, generics minimal). Actual rebates are confidential and vary widely by drug — this is a range, not a fact about this drug.

Estimates: latest NADAC unit price × quantity. Pharmacy acquisition cost only — excludes dispensing fees, markup, and insurance terms.
