I think there is an awful lot of time discussing how hard it is to maintain Coumadin and many tend to forget why it is that Coumadin has to be taken.
For mechanical heart patients, it is given to prevent clot formation on the mechanical valve. It is a very, very necessary medication, as Al has said many times, your life could be ruined by forgetting to take your Coumadin, the flip side of the coin is that if you do not get regular testing, your INR could get dangerously high or dangerously low.
Make this the most important pill of your day if you have a mechanical valve. Your heart valve will not do well without this protection, even for one day.
