Why is the comparison with Medicare for FIRVANQ 50 MG/ML SOLUTION 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 Firvanq / Vancomycin HCl: 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 brand name.

Why does this page start at 1 mL?

The FDA package description of NDC 65628-0206-05 (“1 KIT in 1 CARTON (65628-206-05) * 7.5 g in 1 BOTTLE * 145 mL in 1 BOTTLE”) does not give one amount in mL, NADAC’s unit for this product. So the card starts at 1 ML; change it to match your prescription.

What it is

FIRVANQ 50 MG/ML SOLUTION is how the CMS NADAC file names this product. The FDA NDC Directory lists it as vancomycin hydrochloride, under the trade name “FIRVANQ”.

FDA gives its dosage form as kit.

The labeler, the company named on the label, is Azurity Pharmaceuticals, Inc.

What pharmacies pay

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 mL? Is it lower than what I would pay through my insurance?
How much is in the package I am getting? This page uses 1 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.
