Hey everyone. Just thought I'd pass along this bit of info. I have been on Warfarin since Sept. 14, 2007. Recently, I went to my immunologist/allergist, who also was an internal medicine doctor but her background is in LAB/PHARMACEUTICALS. She was telling me that coumadin is one of those drugs that it pays to get the real brand coumadin instead of generic (warfarin). Apparently, the binders and/or whatever else goes into the generic form can affect your INR levels b/c the drug is not as "pure" as coumadin. So, I decided to switch from the warfarin and see what happened. Lo and behold, she was right. As soon as I switched to the brand name coumadin, my INR shot up through the roof (over 6.0) even though my dosage was the same as the warfarin dosage (5 mg daily). This doctor told me that getting on coumadin and staying on coumadin and not warfarin should help get the INR where it should be and stay that way. This should eliminate all the fluctuations on a weekly basis, assuming you don't vary your diet and eat the foods from the no-no list. I've kept my diet the same the whole time and switching to brand name was the only thing I changed, so there has to be some truth to this. Now my coumadin dosage is smaller and it seems to be working like it should. My hematologist (and even a vascular surgeon that I saw for a consultation) said there was no difference between the generic and brand name, but obviously the doctor with the lab background knew what she was talking about.
