The spread

0.83× estimated

Medicare paid 17% less than pharmacies pay.

Part D averages every strength and form sold under “Ery” / “Erythromycin Base In Ethanol” into one figure, so it is not specific to this NDC.

Cost-plus estimate

$6.41 estimated

$1.23 + $0.18 (15%) + $5.00 fee per fill = $6.41

This is a model, not a price any pharmacy quoted. Shipping is not included. For a pack this cheap, the $5.00 fee is most of the estimate. How it is worked out

What Medicare paid

Medicare Part D paid $1.03 for 1 unit (EA), at an average of $1.02817 per EA in 2024 (2024-01-01 to 2024-12-31) for “Ery” and “Erythromycin Base In Ethanol”, every strength and form sold under that name together (Medicare Part D Spending by Drug, file of 2026-06-25).

That average covers 1,345 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.

Questions

Why is the comparison with Medicare for ERY 2% PADS 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 Ery / Erythromycin Base In Ethanol: all makers, strengths, forms and routes combined, claim-weighted; gross cost incl. dispensing fees and patient pay, before rebates. Unit taken as NADAC's EA. Joined on brand name.
Why does this page start at 1 unit (EA)?
NADAC prices this product per EA, and the FDA NDC Directory lists its NDC as dosage form “SWAB” with route “TOPICAL”. Only a tablet, capsule, lozenge or troche with route “ORAL”, or a tablet or film with route “SUBLINGUAL” or “BUCCAL”, starts at 30, and this is not one. NADAC’s EA for it may be a whole package (such as a kit, pen, syringe, vial or inhaler) or one dose inside it, and the files do not say which. So the card starts at 1 unit (EA) rather than guess how many make up a fill; change it to match your prescription.
