OMEPRAZOLE: what pharmacies pay, and what that tells you
OMEPRAZOLE costs a pharmacy a median of $0.0504 per unit. That is what the pharmacy pays to acquire it. It is not your price: a dispensing fee and margin sit between this number and your receipt.
The same name covers two different products here
OMEPRAZOLE appears in the federal pricing data as 2 distinct products, and they are not the same purchase. At least one is sold over the counter and at least one is prescription-strength, which is why their acquisition costs differ even though the name on the box does not. A single headline price for OMEPRAZOLE would be averaging two different transactions, so the table below keeps them apart and marks which is which.
Where it sits against every other priced drug
Acquisition cost percentile, 3,439 priced products
This is among the cheapest products in the corpus. At this level the pharmacy’s dispensing fee is usually the larger half of your bill.
The other forms of OMEPRAZOLE
CMS prices 2 distinct OMEPRAZOLE products. They are not interchangeable and their costs are not comparable to each other, which is exactly why a single headline price for a drug name is usually meaningless.
The Sold as column is usually the reason two rows differ: an over-the-counter product and a prescription-strength one carry the same drug name and are priced as different products entirely. Unit matters as much: a price per tablet and a price per millilitre are not the same measurement.
| Product | Unit | Class | Sold as | Per unit | Listings |
|---|---|---|---|---|---|
| OMEPRAZOLE DR (shown above) | EA | Generic | Rx | $0.0504 | 2,715 |
| OMEPRAZOLE DR | EA | Generic | OTC | $0.3997 | 639 |
What the spread tells you about shopping around
Between the cheapest tenth of listings and the dearest tenth, OMEPRAZOLE varies by 2.6 times. That is a wide band, and it means the same product genuinely costs different pharmacies different amounts. It is one of the cases where calling around can change the number.
The drug is cheap. The route is what costs you.
OMEPRAZOLE costs a pharmacy $0.0504 a unit. Almost none of what you pay is that number. A dispensing fee and a margin sit on top, and both are set by where you fill it and under what programme. These are the routes worth checking, and what each one is actually for.
- Cost Plus Drugs sells at a stated markup over its own acquisition cost, so the pharmacy margin is visible rather than inferred. What we found
- Honeybee Health a mail-order pharmacy that posts cash prices publicly, which makes it a useful sanity check on any card quote. What we found
- Amazon Pharmacy mail order, so it competes on the dispensing fee rather than on the drug. What we found
- GoodRx a discount card negotiated per pharmacy, so the same drug can differ between two shops on one street. What we found
- SingleCare the same mechanism as a rival card, and worth checking against it rather than instead of it. What we found
- RxSaver another card on the same model; cards are cheap to compare and routinely disagree with each other. What we found
- WellRx a fourth card, listed because checking one card and stopping is the most common way to overpay. What we found
- Blink Health prepay-then-collect, which prices the drug before you reach the counter. What we found
- Costco membership pharmacy pricing, which US federal law makes available without a membership. What we found
- Walmart a flat-price generic list, which beats a card on some drugs and loses badly on others. What we found
- CVS and Walgreens, the default retail route, and usually the one every other option is measured against. What we found
We do not quote a per-pharmacy price for OMEPRAZOLE, because that varies by pharmacy, by ZIP code and by week, and we have not measured it for this drug. What is measured here is the acquisition cost above, from CMS NADAC. The order of these routes is editorial and fixed; it is not for sale, and no placement here implies a medical recommendation.

What this page is, and is not
Every figure here is CMS NADAC, the federal survey of what retail pharmacies pay to acquire a drug. It is public-domain federal data and it is the cleanest available floor. It excludes your dispensing fee, your pharmacy's margin, your insurance design and any discount-card pricing, all of which sit between this number and what you hand over. Nothing here is medical advice.
