The generic form of Warfarin (Warfarin Na) contains the same active ingredient and is bioequivalent to the brand. Ask your pharmacist to dispense the generic — it works the same way at a fraction of the cost.

Warfarin is prescribed to prevent blood clots, stroke, and other cardiovascular events. It is sold under the brand name Coumadin and is available as the generic Warfarin Na. A standard supply is 30 5mg.
Pharmacy pricing is not regulated in the United States, so retailers set their own cash prices. Large retailers like Walmart and Costco typically offer lower prices on generics because they use prescriptions as a traffic driver. Chain pharmacies like CVS and Walgreens tend to charge significantly more.
Anticoagulants vary dramatically in price. Older drugs like warfarin have cheap generics, while newer DOACs (Eliquis, Xarelto) remain expensive without insurance.
Shop around. The cheapest pharmacy (Costco at $3.80) charges significantly less than the most expensive option ($15.50). A quick call can save you real money.
Ask for the generic. If your doctor prescribed the brand-name Coumadin, ask your pharmacist whether the generic Warfarin Na is available. In most states, pharmacists can substitute a generic unless the prescriber writes 'dispense as written.'
Use a discount card. Services like GoodRx, SingleCare, and WellRx can sometimes negotiate prices lower than retail cash. The estimated GoodRx low for Warfarin is around $3.30.
Coverage depends on your specific plan and formulary. Most blood thinners medications are covered under standard health insurance, typically in Tier 1 or Tier 2. If your copay is higher than the cash price above, it may be cheaper to pay out of pocket — ask your pharmacist to compare.
