I am hoping you can help clarify some questions. I have been taking warfarin/coumadin for at least 10 years and have always had it under control never a problem. Dec. 27, 2013 I was put on Glimepiride 2 mg for diabetes. Jan 21. 2014 my INR was tested at 3.5, today it tested at 4.2. My blood is too thin and The Dr. instructed me to stop the warfarin for 2 days, eat lots of spinach and come in Thurs. for another test. I have always been told that Greens - K vitamins, thicken the blood ...correct? Is this the right course of action? I take coumadin/warfarin because my blood clots..particular to me. I am allergic to penicillin, sulfa, niacin...I am aware that Glimepiride has a small amount, but hasn t bothered me...other drugs in this category are highly allergic for me. Thank you
