I have been on Flecainide for a couple of months. Began with 100mg twice a day. Afib would awaken me at about 2:30 or 3 in the morning. I would have to get up and sit in my chair and a while after taking meds at 5 A.M. The AF would correct itself. Dr. increased dose to 150 mg twice a day and I slept through the night, but after a week I could hardly carry my 20 lb. grandson to the car and I was so tired I avoided regular activities. I would also get an odd, brief feeling that I was going to lose consciousness.
Now I take 100 mg in the a.m. and 150mg in the evening. I sleep fine but now the tiredness and odd feeling have returned. Does anyone take a larger dose on a different schedule like taking the 150 mg every other day? I am not scheduled to see my cardiologist for a couple of months. Thanks.
