I too am on lifetime coumadin and aware of the necessity
to juggle Vit K intake to maintain a proper INR.
A drawback of Coumadin is that it creates a deficiency
of Vit K in order to anticoagulate.
There is research coming in on the effects of Vitamin
K deficiency and increased osteoporosis. Although the anticoagulation
needs take priority here, is there any hopes that the new
oral anticoagulant, EXANTA (Ximelagatron) may, in the
future, be a reasonable substitute for coumadin for those
under treatment for osteoporosis? Might it too have a
side effect worse than Coumadin? Liver?
I realize that this is early on,but looking down the
road to a possible bone fractures that may be
exacerbated by low Vit K, causes me concern.
Thank you,

From one a-fib coumadin patient to another ,when I eat a lot of green vegetables high in VitaminK in the summer my blood levels go a little wacky and my coumadin dose has to be adjusted to the appropriate dosage.My doc and some studies I've read say no to vitamins IF you are eating a balanced diet containing all necessary food groups and amounts.If you maintain the same diet usually INR will remain the same and not flucuate much from month to month. As far as the A-fib is concerned my info says not usually for disappearing.If the a-fib is the result of valve problems and the ventricle enlarging then if the valve is repaired it sometimes goes away.Unfortunately, most of us are stuck with it for life,as we age the incidence of atrial fib increases.
Dear terk,
Vitamin K counteracts the effects of coumadin. You should not take any multi-vitamin which may contain vitamin K while you are on coumadin. Vitamin C is not known to interact with coumadin as severely as vitamin K.
If are continuing to experience severe symptoms associated with your atrial fibrillation, I would recommend seeing a specialist in electrophysiology. This is a doctor who specializes in rhythm disturbances such as atrial fibrillation. You may be candidate for more aggressive medical therapy or for an atrial fibrillation ablation. I would recommend contacting the Cleveland Clinic's web site (www.ccf.org) for more information or calling to schedule an appointment at 1-800-CCF-CARE.
Thanks for your question,
