I have been taking 75mg Pradaxa twice a day since I was diagnosed with A Fib 2 years ago and at my yearly check up with my EP he said I should be on 150mg instead. He said I should have been on 150 and that 75 was not enough. I questioned this as I don't like being on NOAC anyway and now on double the does. Just wondered if anyone else was on the 75mg dose for A Fib. When I first was diagnosed I was on just aspirin and Coreg but since I am female and 68 doc says I need anticoagulant. Just wish he hadn't upped me to the 150 as am afraid the risk of bleeding will be much worse.
