Warfarin is an anticoagulant used to prevent blood clots from forming or growing larger in your blood vessels. Often referred to by the misnomer “blood thinner,” anticoagulants, such as warfarin (or a brand of warfarin such as Coumadin®), help prevent clots from forming in the blood by decreasing the clotting ability of the blood.
Anticoagulants are prescribed for those at increased risk of developing harmful blood clots, including people who have experienced an irregular heartbeat or those with a mechanical heart valve. Your doctor may have also prescribed warfarin if you have experienced a stroke, heart attack, a clot that traveled to the lung, or a clot in the leg. People taking warfarin will need to test their blood on a regular schedule.
Most people on warfarin notice they bruise more easily than before they started the medication, or it takes longer for their blood to clot if they get cuts. Although such symptoms are common warfarin side effects, you should contact your healthcare provider if you experience them.
Contact your physician immediately if you experience any of the following:
INR stands for International Normalized Ratio, and it is a standardized number that measures the amount of time it takes for your blood to clot. People taking anti-clotting medicines or anticoagulants need to test their blood regularly to ensure their INR remains within the range deemed best for them by their physician. And the “best” testing frequency is the one your doctor prescribed for you.
Regular testing may not be easy if you have your blood drawn at a lab or doctor’s office. Monitoring your INR at home requires a prescription and the support of your doctor, but people who test their INR at home eliminate the need to travel to a lab or their healthcare provider for routine testing. And Medicare and many private insurance companies cover home INR Monitoring.
You should take warfarin EXACTLY as your doctor prescribes it to you. Most doctors ask people to take their warfarin at the same time every day, preferably in the evening. While you are on warfarin, it will be necessary to check your blood to see if the medication is doing its job and remains within your physician-prescribed range. Checking your blood will require a blood draw or a fingerstick to check your INR, the measurement that represents the time it takes for your blood to clot.
Your INR meter is designed to be portable and packable, no matter where you go. Whether you are traveling for the day or a month, you’ll never have to miss a test or try to find a local lab when you are part of Acelis Connected Health’s home testing service.

The INR (International Normalized Ratio) is a blood test measuring how long it takes for your blood to clot. It tells your doctor or nurse if your warfarin dose needs adjusting or is at the correct level for you. Being within your prescribed range one or two times in a row does not mean your next test will match your previous results. Many things, including the foods you eat and the medication you take, can affect warfarin’s effectiveness. The only way to know if you are in range is by performing an INR test.

While taking warfarin it is important to inform your doctor about the prescription and over-the-counter medications you take, including pain relievers, cold medicines, and herbal supplements.
Understanding how diet can affect your INR is essential to living a healthy life while on warfarin. Although there is no specific “warfarin diet,” it is important to pay attention to what you eat while taking warfarin, as some foods and beverages can alter its effectiveness.
The most important thing to remember is to remain consistent with your diet. Consistency in diet means being aware of the type of foods you choose every day, paying attention to your portion sizes, and being aware of how frequently you consume foods high in Vitamin K.
We will remind you! If you or your loved one doesn’t report their test results according to the testing schedule prescribed by the doctor, our Testing Services team will reach out to remind them.
