I m taking 50mg (25mg twice day) metoprolol for hypertension and 150mg (75mg twice day) flecainide for afib. I ve been on flecainide for 2 months and have had no afib episodes apart from a couple during the first 2 weeks of taking flecainide. Prior to this, over the past 10 years, my afib episodes went from about a few times a year lasting 3 - 4 hours, to a few times a month, to a few times a week lasting about 12 hours each time. I had to take something because of the discomfort and danger of stroke. Both seem under control with meds. Why would I be prescribed a blood thinner (either Apixaban, Riveroxaban of Dabigatran (whichever my drug plan covers)) if I don t have any episodes of afib. I take low dose Aspirin daily but am very reluctant to progress to the new blood thinners.
