[|AI|]  Hi, dairy have gone through your question. I can understand your concern.  You should stop citron before surgery. INR should be around 1 at the time of surgery. After surgery, you should start your anticoagulant.  INR should be maintained between 2 and 3 afterwards. Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
