I have been on warfarin 6.5 mg for over two years, but my last two INR test were above 3.9 and 5.8. I have not changed my normal eating habits or foods. I have not added any new drugs and I have not drank any alcohol. I would like to have a list of food that INCREASES INR, I can find info on food that decrease in INR but not those that Increase INR time?
