Will Vitamin B have an effect on my INRs?

I am on Coumadin for life, and have recently developed "Burning Mouth Syndrome." I have tried to help the problem with Vitamin B Complex. My INRs have dramatically dropped. (I home test.) Question: Would Vitamin B Complex have any effect on the Coumadin/INR?

The Health meets Food Team Says...

I'm sorry to hear that you are experiencing burning mouth syndrome. I have had a few patients with this, and because no one is sure exactly what causes this, it can be very frustrating to treat. Unfortunately, there is no evidence that any of the B vitamins is helpful. We often will try using Vitamin B12 injections to treat burning mouth syndrome, but the results are disappointing.

There should not be any interaction of the Vitamin B supplements with Coumadin, but I always ask my patients who are on any medication (especially Coumadin® / warfarin) to check with me about taking any type of supplement, whether those are plain vitamins or other supplements. Talk with your doctor about this and be sure to take all of the medications and supplements you use regularly with you when you do so that he or she can check for any interactions.

Thanks for writing.
