Medicare paid about 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 56.7 g? Is it lower than what I would pay through my insurance?
- How much is in the package I am getting? This page uses 56.7 g; 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 SULFAMYLON 8.5% CREAM 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 Sulfamylon / Mafenide Acetate: all makers, strengths, forms and routes combined, claim-weighted; gross cost incl. dispensing fees and patient pay, before rebates. Unit taken as NADAC's GM. Joined on brand name.
- Why does this page start at 56.7 g?
- NADAC prices this product per GM. The FDA NDC Directory’s package description gives 56.7 g in one package for this product’s NDC (“1 TUBE in 1 CARTON (16571-723-60) / 56.7 g in 1 TUBE”), so the card starts at one package: 56.7 GM. Change it to match your prescription.
