Buy Coumadin (Warfarin) Online

Are you looking to buy Coumadin and other prescription medications for a fraction of what you usually pay? Buying medications with Canada Pharmacy Depot can save you up to 90% on the cost of Coumadin. It’s safe, convenient and quick from our reputable Canadian pharmacy and you can order online or call us 7 days a week.

What is Coumadin?

Coumadin contains warfarin and is used to treat blood clots, often caused by deep vein thrombosis (DVT) or pulmonary embolism (PE). Warfarin is an anticoagulant (or “blood thinner” medication”) and helps to treat blood clots by decreasing the amount of clotting proteins within your blood. Preventing blood clots can help to reduce the risk of heart attack or stroke.

Always read the patient information and instructions carefully before using this medication. Follow your doctor’s directions.

  • Coumadin should be taken at the same time each day.
  • You should never take a double dose of warfarin.
  • You may need frequent tests to measure blood clots while taking this medication.

  • If you have any drug or other allergies.
  • Which other prescription and non-prescription medications you currently take.
  • Your medical history especially of high blood pressure, blood cell disorders, ulcers, internal bleeding, heart infections, aneurysms, heart disease, kidney disease, cancer, low blood cell counts, stroke, diabetes, congestive heart failure, liver disease, hereditary clotting deficiency or low blood platelets.
  • If you are sick with fever, flu, diarrhea or chills or if your body weight changes.
  • If you are planning on changing your diet. Some foods can make Coumadin less effective.

Real Customers, Trustworthy Reviews

Read what others have to say before you buy — honest reviews from real people.

We have had very good service from the Canada Pharmacy Depot, obtaining a very expensive medication (in the USA) for the very same medication from India for a fraction of the US cost ($488/3mo supply vs $1400/1mo supply). This has been a godsend bc my husband has Parkinson's Disease and takes many medications to manage his condition. It does take longer to get the medication, but you just have to plan ahead for significant savings.
