Why is the comparison with Medicare for ACETIC ACID 2% EAR 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 Acetic Acid* / Acetic Acid: 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 2 NADAC NDCs the name join matched to it have an FDA route including AURICULAR (OTIC).

Why does this page start at 15 mL?

NADAC prices this product per ML. The FDA NDC Directory’s package description gives 15 mL in one package for all 2 NDCs of this product (“1 BOTTLE in 1 CARTON (52817-816-15) / 15 mL in 1 BOTTLE”), so the card starts at one package: 15 ML. Change it to match your prescription.

Medicare paid 50% less than pharmacies pay.

Part D averages every strength and form sold under “Acetic Acid*” / “Acetic Acid” 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 15 mL? Is it lower than what I would pay through my insurance?
How much is in the package I am getting? This page uses 15 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.
