Also, remember that although warfarin (coumadin) is cheaper for the pills, it also requires huge amounts of
monitoring. During the start of
warfarin your wife will have to go to the anti-coagulation clinic every 4-7 days for them to stabilize her dose. After that every month and only after she is stable for a long time could it be every 3 months. These visits come with their co-pays and deductibles too! Not to mention that warfarin has significant risks, drug interactions, food restrictions etc.
