Hi, I have PAF, diagnosed 5 years ago.I am now 64, I have a Chads of 1, being female.My father now 86 has AF, so possibly a genetic link. I had pneumonia twice last winter and due to Warfarin contraindications had a long course of antibiotics.I have allergies to Penicillin, sulphur and Ciprobay. So I was considering a NOAC, Dr suggested Pradaxa .I hate the prospect but stopped Warfarin 3 days ago, waiting for INR to drop to 1.5 before starting the Pradaxa. Today I read the research on Pradaxa and liver issues. A warning issued this year in Canada and Japan. I was so anxious and have started the Warfarin again.I self monitor and will hope that in 3 days INR should be back between 2-3. Any advice anyone?
