8, my cardiologist tells me to take an extra 1/2
warfarin does for one or even two nights. My regular is 5
mg at bedtime. Then, given my history of being stable they do not ask me for a followup check until my regular every 4 weeks. I still go to the hospital for blood tests.
Now for me I can also say when I am over, say 3.2, I don't have any bleeding problems that I can detect, thus my fear of going over 3.0 is minimal. I believe people with a mechanical valve are normally in the 3.
