Warfarin Price Guide – What You Need to Know

If you take warfarin or are about to start it, the first question is usually, "How much will it cost?" In Canada the price can vary a lot depending on where you shop, whether you use the brand name or a generic, and if you have insurance. This guide breaks down the numbers, shows what drives the cost, and gives you simple steps to save money.

What Determines the Price of Warfarin?

Warfarin comes in two forms: the brand name Coumadin and several generic versions (5 mg, 2.5 mg, etc.). The generic is far cheaper because it doesn’t carry the brand‑name premium. On average, a 30‑day supply of generic warfarin 5 mg tablets runs between $15 and $30 at most brick‑and‑mortar pharmacies. The brand name can be $70‑$100 for the same supply.

Other factors that push the price up or down include:

• Pharmacy type: Large chains often have discount programs, while small independent stores may charge a bit more.
• Provincial drug plans: If you’re covered by a provincial formulary, the out‑of‑pocket cost can drop to under $5.
• Insurance coverage: Private plans usually cover a percentage of the cost. Check your policy for the exact co‑pay.
• Quantity discounts: Buying a 90‑day supply can shave $5‑$10 off the per‑day price.

Where to Find the Best Warfarin Deals

Here are three practical ways to keep the cost low:

1. Use a reputable online Canadian pharmacy. Many licensed sites list generic warfarin for $12‑$18 per 30‑day pack. Look for a pharmacy that displays a valid Canadian pharmacy license and a pharmacist’s contact info.

2. Check your provincial drug benefit program. Ontario’s OHIP+, BC’s Fair Pharma Service, and similar programs often list warfarin as a covered drug. Register online, upload your prescription, and you’ll receive a card that reduces the price at participating pharmacies.

3. Ask your doctor about dose adjustments. If you’re on a high dose, a small reduction can mean fewer tablets and lower cost. Your doctor can safely calculate a new dose based on your INR results.

Don’t forget to compare prices before you buy. A quick phone call to three local pharmacies can reveal a $5‑$10 gap. Some chains also have loyalty cards that give you an extra discount after a few purchases.

Finally, keep an eye on special promotions. Pharmacies often run “discount days” where generic anticoagulants are offered at a reduced price. Signing up for their newsletters or loyalty apps can alert you when those deals happen.

Saving on warfarin isn’t a mystery. By choosing the generic version, checking provincial coverage, and shopping around—online or in‑store—you can keep your out‑of‑pocket cost well under $20 per month. Stay on top of your INR, follow your doctor’s advice, and enjoy peace of mind knowing you’re getting the best price.
