Medicare
We don’t know yet
No Medicare reference price. Part D: OpenBill did not match this NDC to a usable Medicare Part D spending row. Either Part D has none for it, or the rows that share its name could not safely be tied to it (for example, they mix units, routes or release forms, or the drug is sold over the counter, which Part D does not cover). Part B: This NDC is not in the current quarter’s Medicare Part B NDC-HCPCS crosswalk, so it has no Part B payment limit.
The spread
We don’t know yet
There is no Medicare figure to compare with, so there is no spread.
Cost-plus estimate
$7.53 estimated
$2.20 + $0.33 (15%) + $5.00 fee per fill = $7.53
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 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 251 mL? Is it lower than what I would pay through my insurance?
- It is sold over the counter, so shelf prices vary from store to store: what does it cost per unit here?
- How much is in the package I am getting? This page uses 251 mL; your package may hold a different amount.
- These are questions about price, not medical advice. Do not change or stop a medicine without talking to your prescriber or pharmacist.
Questions
- Why does this page start at 251 mL?
- NADAC prices this product per ML. The FDA NDC Directory’s package description gives 251 mL in one package for this product’s NDC (“251 mL in 1 BOTTLE, PLASTIC (0904-5259-44)”), so the card starts at one package: 251 ML. Change it to match your prescription.
