I just thought I would add my personal experience to the thread. After surgery, my surgeon made it very clear to me that I should never get the generic brand for Coumadin. So, I have been sticking with the name brand Coumadin ever since. I have also read many stories on this and other medical related sites that have tried to use the generic and have had problems stabilizing their INR.
As for generic versus name brand products, the quality specs for the generic have a wider tolerence for the amount of the drug used in each pill. What this means is that the name brand for a drug may call for 5 mg. The manufacturing process may allow for a "+" or "-" factor of lets say "0.1" mg. But, the specifications for the genieric brand may have a wider tolerence factor of let's say "+" or "-" 0.5 mg. This means that the generic brand could cause more or less doasage than prescribed.
While it is true that both brands have the same quality, they may not have the exact same amount of the drug.
Now, all that being said, let's not forget the possibility of "Name Brand" loyalty. Afterall, the drug companies are the ones that wine and dine the doctors! So, who's name brand loyalty is it? Ours, or the doctor who told us to take it. Just another thought.
Personally, I stay for the most part within my recommended INR range on Coumadin, so that is my prefered drug of choice. Medically speaking that is!
Wishing everyone good health and safe holidays,,
