Dear Dr. Gourmet,

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?

Dr. Gourmet Says...

I have had a few patients with burning mouth syndrome. No one is sure exactly what causes this and it can be very frustrating to treat. 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 with Coumadin, but I always ask my patients who are on any medication (especially Coumadin® / warfarin) to check with me about adding any type of supplement. Chat with your doctor about this.

Thanks for writing,

Dr. Gourmet
