Medicare

We don’t know yet

No Medicare reference price. Part D: OpenBill did not match this NDC to a usable Medicare Part D spending row. Either Part D has none for it, or the rows that share its name could not safely be tied to it (for example, they mix units, routes or release forms, or the drug is sold over the counter, which Part D does not cover). Part B: This NDC is not in the current quarter’s Medicare Part B NDC-HCPCS crosswalk, so it has no Part B payment limit.

The spread

We don’t know yet

There is no Medicare figure to compare with, so there is no spread.

Cost-plus estimate

$5.14 – $5.23 estimated

NADAC for the pack + 15% + $5.00 fee per fill

This is a model, not a price any pharmacy quoted. Shipping is not included. For a pack this cheap, the $5.00 fee is most of the estimate. How it is worked out

What it is

NAPROXEN 125 MG/5 ML SUSPEN is how the CMS NADAC file names this product. The FDA NDC Directory lists it as “naproxen” and “naproxen oral”, as its NDCs’ listings variously write the nonproprietary name, under the trade name “Naproxen Oral Suspension”.

FDA gives its dosage form as suspension and its route as oral.

FDA lists 5 labelers (the companies named on the label) for its NDCs, among them Hikma Pharmaceuticals USA Inc., Camber Pharmaceuticals, Inc. and Acella Pharmaceuticals, LLC.

The NADAC file of 2026-10-14 prices it under 5 NDCs (National Drug Codes).

What pharmacies pay

Pharmacies pay $0.12 – $0.20 for 1 mL, depending on the NDC ($0.12157 to $0.20183 per ML), by the CMS NADAC file of 2026-10-14; that price took effect on 2026-09-23. That is what pharmacies pay their suppliers, not what they charge you.

NADAC’s explanation codes for it: 1, calculated from the most recently completed pharmacy survey; 5, calculated based on package size; 6, the CMS Covered Outpatient Drug Product File S/I/N drug category was not applied when grouping drugs for the calculation.

Which NDC (the 11-digit number on the package) is this? Pharmacies pay $0.12157 to $0.20183 per ML for this product, depending on the NDC.
How much is in the package I am getting? This page uses 1 mL; your package may hold a different amount.
