For Atrial Fibrillation "Coming up on 1 year of Tambocor Metoprolol for treatment of atrial fibrillation. It works very well, no attacks at all since starting Tambocor, hence, my life is better in that respect. However, there is a trade-off, my energy level is lower, and I feel exactly the same when I get up at 7:30 in the morning, whether I go to bed at 9:00 PM or stay up until after midnight. I am chronically tired. Also, I notice strange things with my peripheral vision occasionally since on the Tambocor. That's not to scare anyone off, I can still function normally, from yard work, to splitting wood, to playing golf, on the outside, I doubt anyone who knows me has a clue that I am on medication. It is a 'feeling' to me. I can tell I am a little 'off,' but it's worth it."

For Atrial Fibrillation "Initially, it worked with minimal side effects. But after one year, I have virtually all known side effects for this medicine, including severe fatigue and shortness of breath - or inability to get a full breath. I attributed these to mold in our soil due to construction and did not look at side effects until my EP's total lack of concern made me wonder if he was hiding something. I am shocked by what I now read and have no idea what to do - obviously, reporting to my EP is not the answer. My GP says she knows nothing about cardiology."

For Atrial Fibrillation "I’ve been on flecainide for about a year and a half. For 30 years, I tried all manner of other medications, including Toprol XL and other beta blockers, in an attempt to control my pre-ventricular contractions and pre-atrium contractions. The other medications did little to control the arrhythmias, and the doctor put me on flecainide once my arrhythmias started to be trigeminy. Within a day of taking flecainide, I experienced no irregular heartbeats. Flecainide has controlled my arrhythmias very well over the last year and a half, and there are often times when I go days without any skips. I continue to take meta-Toprol along with the flecainide. The only side effect I’ve experienced is slight fatigue."
