Why is the comparison with Medicare for CROTAN 10% LOTION 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 Crotan / Crotamiton: 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 454 g?

NADAC prices this product per GM. The FDA NDC Directory’s package description gives 454 g in one package for this product’s NDC (“454 g in 1 BOTTLE, PLASTIC (0682-0051-30)”), so the card starts at one package: 454 GM. Change it to match your prescription.

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 454 g? Is it lower than what I would pay through my insurance?
How much is in the package I am getting? This page uses 454 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.
