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
$5.03 – $5.06 estimated
NADAC for the pack + 15% + $5.00 fee per fill
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 it is
PETROLATUM 42% OINTMENT is how the CMS NADAC file names this product. The FDA NDC Directory lists it as petrolatum, under the trade name “Rugby Petrolatum Hydrating Skin Protectant”.
FDA gives its dosage form as ointment and its route as topical.
The labeler, the company named on the label, is Rugby Laboratories.
FDA lists no Established Pharmacologic Class for it.
The NADAC file of 2026-10-14 prices it under 2 NDCs (National Drug Codes).
NADAC classes it as a generic drug (rate-setting class G), and marks it as sold over the counter.
What pharmacies pay
Pharmacies pay $0.03 – $0.05 for 1 g, depending on the NDC ($0.02623 to $0.04985 per GM), by the CMS NADAC file of 2026-10-14; that price took effect on 2026-09-23. That is what pharmacies pay their suppliers, not what they charge you.
NADAC’s explanation codes for it: 1, calculated from the most recently completed pharmacy survey; 5, calculated based on package size.

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 1 g? Is it lower than what I would pay through my insurance?
- Which NDC (the 11-digit number on the package) is this? Pharmacies pay $0.02623 to $0.04985 per GM for this product, depending on the NDC.
- 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 1 g; 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 1 g?
- The FDA package descriptions of this product’s NDCs give different amounts (100 g, 454 g). So the card starts at 1 GM; change it to match your prescription.
