vic46, yes they (the VA) will retest me weekly if my level gets out of range. I've had two surgeries and both times they have cut off the coumadin and gave me a self injecting anticoagulant called Lovenox. Then when in the hospital I had a heparin drip. I didn't know about the ability to reverse the heparins affect. When I was released I was back on the coumadin and had to do the Lovenox injections for a week. I have inquired about Pradaxa (sp) or another thinner and The Veterans Administration has just started to allow them to be prescribed. I may stick with the rat poison, at least I know the disadvantages of it.
I have learned some new things today and at my age that makes for a good day. Thanks everyone.
