Why is the comparison with Medicare for PREDNISOLONE SOD 1% EYE DROP 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 Prednisolone Sodium Phosphate* / Prednisolone Sodium Phosphate: 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 1 NADAC NDCs the name join matched to it have an FDA route including OPHTHALMIC.

Why does this page start at 10 mL?

NADAC prices this product per ML. The FDA NDC Directory’s package description gives 10 mL in one package for this product’s NDC (“1 BOTTLE, DROPPER in 1 CARTON (24208-715-10) / 10 mL in 1 BOTTLE, DROPPER”), so the card starts at one package: 10 ML. Change it to match your prescription.

The spread

0.16× estimated

These two figures may not measure the same thing

At 0.16×, the Medicare figure is 0.2 times what pharmacies pay or less. A gap that large means the two figures may not describe the same unit or product, or the price may have changed between their dates; check what each one covers before relying on the multiple.

Part D averages every strength and form sold under “Prednisolone Sodium Phosphate*” / “Prednisolone Sodium Phosphate” 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 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.
