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 2 mL? Is it lower than what I would pay through my insurance?
- How much is in the package I am getting? This page uses 2 mL; your package may hold a different amount.
- 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 GENTAMICIN 80 MG/2 ML 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 Gentamicin Sulfate* / Gentamicin Sulfate: all makers, strengths, forms and routes combined, claim-weighted; gross cost incl. dispensing fees and patient pay, before rebates. Unit taken as NADAC's ML. Joined on generic name. *: CMS says this average reflects multiple routes of administration, which may have different unit prices. All 4 NADAC NDCs the name join matched to it have an FDA route including INTRAMUSCULAR and INTRAVENOUS.
- Why does this page start at 2 mL?
- NADAC prices this product per ML. In the FDA NDC Directory, 5 of this product’s NDCs are wholesale packs of identical units, so OpenBill counts one unit of each; for example, NDC 00143-9128-25 (“25 VIAL in 1 CARTON (0143-9128-25) / 2 mL in 1 VIAL (0143-9128-01)”) is a carton of 25 vials, 50 mL in all. So the card starts at one unit: 2 ML. Change it to match your prescription.
