Last Monday, at the doctors surgery, when I had my INR taken it was 6.5 and the way my blood flowed out after the finger prick was very worrying. It had been just over a week since I'd had my previous one. I had to stop taking my warfarin and go back next day where it was then 4.5 - no warfarin again. The following day Wednesday it was down to 2.3 and I was told to restart warfarin at a slightly lower dose and go for another test in a weeks time. I guessed my INR was high because I'd been taking massive doses of amiodarone 1 week 3 tablets per day, 2nd week 2 tablets per day and third week and henceforth 1 tablet per day. Those of you who take amiodarone will know that it builds up in your body and affects INR results. I've been worried about waiting a week for another test as I'm booked for a cardioversion on 20th November. Today when I went to see my arrithyma nurse, at my main hospital, she did a blood test and I will get the result tomorrow. My question is 'How on earth was my INR allowed to get that high'?
