I am happily on lifetime Warfarin because of an artificial Mitral valve, use a Coaguchek meter, and have been self dosing for over 20 years. Recently had AF, which led to Amiodarone + electrical Cardioversion. I successfully managed the INR change when I started Amiodarone. I figured a dosage change would be needed within a week, and I was right. I recently stopped Amiodarone. Q1. Roughly when can I expect to start increasing my Warfarin? Q2. Will the change happen gradually, or could it happen suddenly?
I have searched far and wide for information, and I have some access to medical journals etc, but have only found advice on starting Amiodarone, not stopping it.
Meantime, I am running my INR high, so that when the change happens, there is margin, and testing weekly.
