Q. I am having trouble leveling out my Coumadin. Many foods are not included on the list the dietitian gave me. Cranberries are a puzzle, for instance. The nurse says eat them; the doctor says don’t. Can I eat cranberries or not?
A. Trying to maintain a steady anticoagulant effect from Coumadin (warfarin) can be a little like walking a tightrope. Too much medicine can lead to bleeding, while too little may permit blood clots to form. Coumadin interacts with many foods.
Several cases in Great Britain led the health authorities there to warn against combining cranberries or cranberry juice with the anticoagulant Coumadin (warfarin). Some people who had been on a stable dose of Coumadin had serious bleeding problems after drinking cranberry juice or eating cranberries.
Australian scientists have reported that cranberry significantly increases warfarin’s anticoagulant effect (British Journal of Pharmacology, Aug. 2008). We suggest you follow your doctor’s recommendation and avoid cranberries and cranberry juice while you are taking Coumadin.
I'm on coumadin for life (I had an almost fatal pulmonary embolism 7 yrs. ago). This is the first time I've ever heard of any interaction of cranberries vs. coumadin. I know that too much of anything is not good but I'd imagine it would be OK to have some cranberry products while on anticoagulants. Unless a person is on a high dose of warfarin (coumadin) for current treatment of heart or circulatory conditions, I believe that the healing and health benefits of cranberries would outweigh the risks of a serious drug interaction with blood thinners. I know there are other foods that one should monitor or avoid - like anything with a high amount of vitamin K, which decreases the effectiveness of anticoagulants. May the "experts" correct me if I am wrong! My advice - check with your personal physician, pharmacist or anticoagulation therapist, to find out what is good for you as a patient.
PEOPLE'S PHARMACY RESPONSE: THE CRANBERRY INTERACTION WAS REPORTED IN ENGLAND A FEW YEARS AGO. WE CERTAINLY ENDORSE CHECKING WITH YOUR OWN HEALTH CARE PROFESSIONALS BEFORE CHANGING YOUR DIET IF YOU ARE ON COUMADIN!
Ginger will also thin your blood if you're on coumadin.

My Mother in Law is on Coumadin for blood clots. What other foods does she need to stay away from?
My mom is also on Counadin for blood clots recently. She almost died Jan. 3rd due to a pe near her heart. She's doing good now! I would also like to know what food she should stay away from. Can you tell us? The Dr. didn't mention any but cranberries. Thank you.
