Do not increase your consumption of foods containing vitamin K without discussing your diet with your doctor.

Interactions of Coumadin with food:

• Vitamin K affects how Coumadin works on the clotting factors and is found in many foods and multi-vitamin supplements. Vitamin K rich foods do not need to be avoided, but should be eaten in the same amounts. For instance if you eat broccoli 3 times a week, then stops eating it, the Coumadin level could rise. The opposite will happen if you do not eat broccoli, and then decides to eat it 3 times a week; the Coumadin level may drop.
• Foods rich in vitamin K:
  Broccoli
  Brussel sprouts
  Liver (beef or pork)
  Chick peas
  Cucumber peels
  Greens
  Cauliflower
  Spinach
  Lettuce
  Green tea
• Excessive use or abuse of alcohol is to be avoided as this will lead to major fluctuation in the PT/INR and may lead to excessive bleeding or clot formation. An occasional drink (1-2) may be consumed without problems.

Other things that may affect how Coumadin works:

• Fever (greater than 101 for 24 hours)
• Diarrhea, vomiting
• Use of antibiotics

Notify your doctor if these occur. They may cause your Coumadin level to be too high.
