From my understanding it doesn't take too long. My husband and are thinking about starting a family and when we decide that we want to start trying I need to talk to my hematologist about coming off of Coumadin and getting switched to Lovenox. So, I am guessing here, but a couple of weeks.
I am going to guess about 5 days. The reason I came to this conclusion, is my dad was on it and started bleeding rectally. He was taken to the hospital and it was suspected he had divictulitus. The doctors waited 5 days before doing the colonscopy because they didnt want the coumadin in his system.
I would agree with the five days as when I go for INR each week if I have missed a dose it drops dramatically as thought I am not really on it. I am currently on 5mg and when I miss a day it drops to where it has no effect.
Also if you start eating things with Vitamin K it will get out of your system sooner as it counter reacts it.

Now that I think about it more, you are probably right, the person that I was speaking of was being treated with a lot of meds for blood clots. A lower dose would make sense that it would not take as long. FLFLOWERGIRL

Mel52--Maybe in your father's case it was more of an emergency situation. I think that it takes a little while to be completely out of your system. But I don't know that for sure either. FLFLOWERGIRL
FLFLOWERGIRL, they probably just wanted to get him out of the hospital..Actually he had very heavy bleeding and had to have a transfusion. The bleeding stopped actually very quickly but he had to wait until they said it was safe to do the test. He no longer is on coumadin because of the diviculitus. I was rather concerned but the drs put him back on one aspirin a day.
