"I have been taking flecainide for 23 days. I have feelings in my middle chest and a feeling of fluttering sometimes and a thumping middle chest, foggy head. For 18 days, I have felt awful, dizzy, sick, chest aching, just awful. At 18 days, I began to feel better with on/off dizziness and sickness, these have been decreasing over the past 5 days and today so far nothing, I feel alert, bright, and wonderful. I was about to give up, I spoke to a doctor, a cardiac nurse, and they both said hang on for a while. Now I feel great, hope it works and keeps the atrial fibrillation (AF) away for good. I am so glad I waited, fingers crossed this is it now, feeling good."

"My doctor put me on diltiazem and warfarin three years ago for AFib. This past summer, the AFib got worse, and they put me in a thirty-day event monitor. Followed by a stress test, the event monitor showed many episodes with a heart rate of 150 plus and irregular. I've been on 100 mg flecainide twice a day, along with the diltiazem, for two months, and not one AFib episode and hardly even a skipped beat. I feel great!"

"I'm a male, 72, who works out with weights 2 times/wk and walks golf courses 2-3 times/wk, as well as hits range balls and practices. My resting HR is normally 50. I had my first afib for 8 hours on Valentine's Day 2021 before ER was able to fix the heart with Diltiazem and saline IV. Then I had a second episode 8 months later after hitting 2 buckets of balls in high heat and humidity. 100 mg of Flecainide at ER worked 1 hour after administration. Now I take 100 mg 2/day to keep me out of AFIB. I have taken it for 3 weeks with no side effects yet."

"I have paroxysmal AFIB, which showed up several times a week for a few minutes to several hours in duration. My cardiologist put me on 50 mgs flecainide twice a day last November (2021). It has been a wonderful relief. Except for a few PACs every now and again, I have been free of AFIB since November. I haven't experienced any side effects that I am aware of."

"I was started on Flecainide for multiple episodes of A-fib on my Holter monitor 7-day test. Within 24 hours of starting Flecainide, I started feeling terrible. I was having a rapid heart rate (feeling) more frequently, flutter sensations, general weakness, and just feeling unwell. I didn't feel it was safe for me to drive because I was feeling so poorly and weak. After 48 hours, I went into the cardiologist's office for a previously scheduled EKG. They took me off Flecainide because of my side effects, and after a 'wash-out' period, I start another drug."

"I found flecainide increased my A.F. episodes. I had 12 episodes in 10 months, then put on flecainide. I then had 32 episodes in a month. It felt awful. Certainly not for me."

"After years of Sotalol and many AF attacks, flecainide has been a wonder drug for me. I get tired, but don't blame flecainide, that's too easy. Many things cause tiredness!"

"I didn’t think I needed another medication for my A-fib, but my doctor prescribed flecainide in addition to metoprolol. My biggest complaint with the flecainide is the taste. It is disgusting!!"
