Warfarin (Coumadin) price comparison 2026: cheapest pharmacy finder

Reviewed by RxGrab Editorial, RxGrab Editorial Team

Federal data puts the wholesale side of this in plain view: Warfarin Sodium costs a pharmacy a median of $0.0876 per tablet to acquire, across 3,441 weekly NADAC price rows for 93 national drug codes, January to 16 September 2026 (CMS NADAC). In the current release (14 October 2026) the median is $0.0961 across 93 national drug codes. Acquisition cost is not the pharmacy’s profit; the counter price also carries dispensing and overhead, which each pharmacy sets for itself. The prices below are what each discount program publishes, and they change, so confirm before you fill. Warfarin is prescribed for preventing blood clots, strokes, and pulmonary embolism and is one of the most commonly filled prescriptions in the United States.

If you are paying out of pocket, where you fill matters. RxGrab shows only prices a program publishes; it does not estimate what a chain pharmacy charges at the counter, because that varies by store.

Warfarin published discount program prices (13 October 2026)

Published program prices as listed on 13 October 2026; retail cash prices at chain pharmacies vary by store and are not shown. Every figure links to the program’s own listing. Walmart notes prices may be higher in some states including CA and MN, and the program is not available in North Dakota. For the full comparison by strength, use our Pharmacy Price Finder.

Costco and Kroger are not in the table because neither publishes a per-drug price list RxGrab can verify: Costco’s member prices sit behind a logged-in lookup at rx.costco.com, and no current official Kroger Rx Savings Club drug list could be found. Discount cards such as GoodRx and SingleCare price by pharmacy; see our discount card guide.

Why Warfarin prices vary so much

Pharmacy pricing is not standardized. Each chain negotiates its own wholesale rates, sets its own markup, and runs its own discount programs. Warehouse pharmacies like Costco operate on thin margins with high volume. Retail chains like CVS and Walgreens price higher but offer convenience and widespread locations.

For Warfarin specifically, the generic has been available since 1997, which means multiple manufacturers compete on price. This competition keeps generic costs low at pharmacies that pass savings through to customers.

How to get Warfarin even cheaper

Even the best pharmacy price might not be the lowest you can pay. Here are proven ways to reduce your cost further:

• 90-day supply: Most pharmacies offer a 15-20% discount when you fill 90 days at once. Ask your doctor to write the prescription for a 90-day supply with refills.
• Discount cards: Free cards from GoodRx, SingleCare, and RxSaver can cut retail prices by 40-80%. Always ask your pharmacist to compare the discount card price against your insurance copay.
• Mail order: Amazon Pharmacy and Cost Plus Drugs ship directly to your door, often at lower prices than brick-and-mortar stores.
• Patient assistance: If your income is below 400% of the federal poverty level ($62,400 for an individual in 2026), you may qualify for free medication through manufacturer programs.

Should you use insurance or pay cash for Warfarin?

This depends on your plan. If your insurance copay for generic Warfarin is $10-$15, that is competitive with the best cash prices. But if you have a high-deductible plan and have not met your deductible yet, you are paying full retail through your insurance, which is almost always more expensive than cash price at Costco or Walmart.

We break this decision down fully in our guide: insurance vs cash price for prescriptions.

If you are a freelancer or self-employed, you may be able to deduct prescription costs as a medical expense. The team at CeoCult covers this in detail for 1099 workers.
