How the class comparison works

What Medicare paid

Medicare Part D paid $8.33 for 10 mL, at an average of $0.8335 per ML in 2024 (2024-01-01 to 2024-12-31) for “Polymyxin B Sul-Trimethoprim” and “Polymyxin B Sulf/Trimethoprim”, every strength and form sold under that name together (Medicare Part D Spending by Drug, file of 2026-06-25).

That average covers 417,816 Part D claims (fills, including refills) for 2024-01-01 to 2024-12-31, across every maker, strength and form under the name.

Medicare's price is not your price.

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 10 mL? Is it lower than what I would pay through my insurance?
• How much is in the package I am getting? This page uses 10 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.
