In brief: For toxicity

If warfarin is well controlled and INR levels are therapeutic (2-3.
5, depending on the disease being treated), Vitamin K is NOT needed. It is only used when the effect of the warfarin needs to be reversed FAST as the patient is bleeding or about to bleed. That is why monitoring levels is so important.
