Hi guys, I am new here. I had been diagnosed with AF 3 weeks ago and I am still in a state of shock. I am 32 yo, active and very fit, not really sure where it came from. My cardiologist put me on 2X100mg Flecainide and 1x2.5 Bisoprolol daily and I think Flecainide is giving me terrible side effects. I either feel very dizzy or very short of breath. It is really annoying and negatively affecting my life. My cardiologist is on holiday until mid-April and I can't ask him to review it. How do you guys find Flecainide? Are there any ways to reduce the side effects?
