What kinds of foods can a person eat who is on coumadin for the rest of their life?

There is no specific warfarin (Coumadin) diet. However, certain foods and beverages can make it so warfarin doesn't effectively prevent blood clots. It's important to pay attention to what you eat while taking warfarin.

One nutrient that can lessen warfarin's effectiveness is vitamin K. It's important to be consistent in how much vitamin K you get daily. The average daily allowance of vitamin K for adult men is 120 micrograms (mcg). For adult women, it's 90 mcg. While eating small amounts of foods that are rich in vitamin K shouldn't cause a problem, avoid eating or drinking large amounts of:

  • Kale
  • Spinach
  • Brussels sprouts
  • Parsley
  • Collard greens
  • Mustard greens
  • Chard
  • Green tea

Certain drinks can increase the effect of warfarin, leading to bleeding problems. Avoid or drink only small amounts of these drinks when taking warfarin:

  • Cranberry juice
  • Alcohol

Talk to your doctor before making any major changes in your diet and before starting any over-the-counter medications, vitamins or herbal supplements. If you are unable to eat for several days or have ongoing stomach upset, diarrhea or fever, consult your doctor. These signs and symptoms may mean you need a different dose of warfarin.
