tea and coffee during warfarin therapy..

Can aspirin increase INR?
An increased risk of bleeding is associated with both a more intense oral anticoagulation (i.e. a higher INR) and the use of aspirin [2–6]. It has also been demonstrated that a greater INR variability is an independent risk factor for major bleeding [7–9] in patients who are chronically anticoagulated.
What increases effects of warfarin?
John’s wort, and ginseng can decrease the effects of warfarin, thus increasing the risk of blood clots. Because high doses of vitamin A or vitamin E can increase the effect of anticoagulation, patients should only take the recommended daily doses based on instructions from their health care provider.
What causes INR to increase?
