M.V.I. Adult contains Vitamin K which may decrease the anticoagulant effect of warfarin. In patients who are on warfarin anticoagulant therapy receiving M.V.I. Adult, prothrombin time/INR should be periodically monitored to determine if the dose of warfarin needs to be adjusted. 5.2 Aluminum ...
Vitamin K deficiency is a common problem in the intensive care unit and a frequent cause of coagulopathy. Causes of vitamin K deficiency in the intensive care unit include prior deficiency, antibiotics, malabsorption, warfarin, and poor oral or enteral nutrition intake for prolonged periods of time...

Warfarin is widely used, but its dominance is being challenged by novel non-vitamin-K antagonist oral anticoagulants such as dabigatran, rivaroxaban, apixaban, and edoxaban.201 Individual response to warfarin is highly variable and is monitored by INR (see Box 11.1).202 A 10% increase in time ...
We compared the effect of withholding acenocoumarol and administering 1 mg oral vitamin K with simply withholding acenocoumarol in asymptomatic patients presenting with INR values between 4.5 and 10.0. The primary end-point of the study was the INR value on......

PURPOSE: Vitamin K (vitK) dose and route of administration prescribing practices for supratherapeutic INR varies among physicians. To standardize our practice and optimize patient care, we propose a study evaluating the relationship between vitK dose, route of administration, and reversal time. METHODS...
Close monitoring and quantified supplementation of vitamin K may be warranted during this period. However, this should not be guided by INR alone, as it is a poor indicator of vitamin K status.doi:10.1002/jpen.1677Dao DTAnez-Bustillos L...
