Abstract:
To clarify whether vitamin E enhances the pharmacologic effect of warfarin, we completed a double-blind clinical trial in which 21 subjects taking chronic warfarin therapy were randomized to receive either vitamin E or placebo. None of the subjects who received vitamin E had a significant change in the international normalized ratio, and thus it appears that vitamin E can safely be given to patients who require chronic warfarin therapy.
