Warfarin is an anticoagulant Anticoagulants help reduce the number of clots forming in blood. Warfarin is referred to as a “blood thinner,” however; it does not affect the thickness of your blood.

4 What is the difference between warfarin and Coumadin®/ Jantoven®?
Coumadin®/Jantoven® are the brand names for warfarin They are all the same drug and will work the same way To avoid confusion, always get your warfarin refilled at the same pharmacy

5 Why do I need to take warfarin?
There are many reasons people need to take warfarin. The most common reasons are: Previous heart attacks Atrial Fibrillation Previous clots in your legs or lung Heart valve replacement

6 How do I know it is working?
The effect of warfarin is shown in blood tests The blood tests measure the INR (international normalized ratio), which tells how long it takes for your blood to clot The INR goal is usually between 2-3 or 2.5 – 3.5, however, your healthcare provider will determine your exact goal

7 How often do I need to get bloodwork?
When you start warfarin your INR will be monitored at least once a week The healthcare provider that manages your warfarin will determine when you need to come in for blood work For your safety it is important not to miss these appointments

8 What affects my bloodwork (INR)?
Illness, diet, beverages, supplements, medications (prescription and over-the-counter), and certain disease states may affect your INR Notify the healthcare provider managing your warfarin about any changes in your lifestyle, health, medications (including herbals and dietary supplements) at each visit. 

9 How do I take warfarin? Take warfarin at the same time each day, preferably later in the evening Take it exactly as prescribed If you miss a dose, skip the missed dose. Do NOT double up! Inform the healthcare provider managing your warfarin when a dose was missed as this may affect your blood levels

11 Should I only eat certain foods while I am on warfarin?
The main thing to remember is keep your diet consistent!! Warfarin is balanced against the vitamin K in your diet (typically found in green, leafy vegetables). Varying the amount of foods high in Vitamin K may cause fluctuations in your INR. Keep your intake of alcoholic beverages consistent (ie: avoid binge drinking).
