The spread
0.57× – 1.0× estimated
Medicare paid between 0.57× and 1.0× what pharmacies pay, depending on the NDC.
Part D averages every strength and form sold under “Ertapenem” / “Ertapenem Sodium” into one figure, so it is not specific to this NDC.

What to ask at the counter
None of these figures is your price: what you pay depends on your pharmacy, your insurance, coupons and discounts.
- What is your cash price for 1 unit (EA)? Is it lower than what I would pay through my insurance?
- Which NDC (the 11-digit number on the package) is this? Pharmacies pay $26.62948 to $47.2056 per EA for this product, depending on the NDC.
- If you have Medicare Part D: what is my plan’s copay or coinsurance for it? The Part D average on this page is not what you pay.
- These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
Questions
- Why is the comparison with Medicare for ERTAPENEM 1 GRAM VIAL labelled estimated?
- Beyond what the card shows, the records give these reasons: The Part D figure covers 2024-01-01 to 2024-12-31; the NADAC price is from the file of 2026-10-14. Part D spending basis, as the Part D record states it: Part D 2024 average spend per dosage unit for Ertapenem / Ertapenem Sodium: all makers, strengths, forms and routes combined, claim-weighted; gross cost incl. dispensing fees and patient pay, before rebates. Unit taken as NADAC's EA. Joined on generic name.
- Why does this page start at 1 unit (EA)?
- NADAC prices this product per EA, and the FDA NDC Directory lists its 14 NDCs as dosage forms “INJECTION”, “INJECTION, POWDER, LYOPHILIZED, FOR SOLUTION” with route “INTRAMUSCULAR; INTRAVENOUS”. Only a tablet, capsule, lozenge or troche with route “ORAL”, or a tablet or film with route “SUBLINGUAL” or “BUCCAL”, starts at 30, and none of these is one. NADAC’s EA for it may be a whole package (such as a kit, pen, syringe, vial or inhaler) or one dose inside it, and the files do not say which. So the card starts at 1 unit (EA) rather than guess how many make up a fill; change it to match your prescription.
