Coumadin and Colonscopy11/30/2011 |
Can one have colonscopy while on coumadin? I am on coumadin and need a screening colonscopy in a few months. I have atrial fibrillation as well. If coumdain must be removed what is the maxinum INR to consider for the colonscopy? Any information is appreciated.
You should check with your doctor who prescribed the coumadin as to whether it can be safely be discontinued, switch you to a shorter acting blood thinner such as Lovenox, or you need to stay on the coumadin. We often do colonoscopies on coumadin with the caveat that if a large polyp is found, we cannot safely remove it. The specific INR threshold depends on the physician's practice.
