For Atrial Fibrillation: "This medication literally killed my mom. They increased it from 50mg to 150 mg twice a day after pacemaker and she slowly declined. Shortness of breath, severe weakness, nausea, no appetite. After 3 months she became toxic from the flecaenide and collapsed at my house. Called the ambulance and she passed away within 21 hours. Total organ shutdown. Her death certificate said flecaenide toxicity. PLEASE BE CAREFUL WITH THIS MED AND INSIST THEY CHANGE IT IF YOU GET ANY OF THESE SYMPTOMS. I had Mom to the cardiologist on Monday with Doppler, blood work, echo, EKG, and pacer check but NO flecainide level was done. All tests were perfect. Called Dr on Tues because she could not even walk. They said she had fluid overload and increased diuretic. She was gone by Thursday. She went from a fit, beautiful, energetic lady in Sept to gone in December. "

For Atrial Fibrillation: "After years of severe AF and trials of sotalol and beta blockers - which didn't control the symptoms and left me with no quality of life - memory loss, muscle aches and tiredness. Flecainide has changed it all. I still get a little bit of AF but not as severe or lasting as long. More like a wee flutter. I take 100mg CR per day at night with food. I have stopped taking sotalol in the morning - I am 59 years old female."

For Atrial Fibrillation: "I am extremely sensative to my AFib. Tried many meds and combination thereof when first diagnosed but they didn't work. In desperation went to a specialist and he put me on Flecainide. This is the only drug that works for me. My AFib ceased immediately and rarely have I had breakthroughs. I have had no ill affects from the medicine and have been on it for over 8 years. I could not function without it."

For Atrial Flutter: "I started taking Flecainide Acetate , it was prescribed for two 100 mg tablets twice a day. I took one the first day and no ill affects. Took the second one the next day and during the night had a bad attack of diarrhea for over twenty minutes in the bathroom. After that it hit again about two hours later the same thing. I won't do into details about what happen then, but I had a bad problem with it. I never had anything like that in my entire life. will talk to the doctor tomorrow about it , or his nurse. Last time I had a bad reaction from a medicine I told the doctor and she said ( it might of been a virus) I had viruses all my life including the flu, and none every acted like this one did."

Tambocor (flecainide) for Supraventricular Tachycardia: "I have been on Tambacor for 7 years now and in the past 2 years I have been having dizzy spells, almost blackout, panic attacks for no reason, breathing problems out of the blue, eyes are blurring up more and more each year, no energy, weak muscles and not for lack of trying I just can't get them to tone up so I consider myself weak. My tummy gets upset ringing in the ears and the most annoying other than the dizziness is the low blood pressure it just drops so times! These are all symptoms for this drug. I was in denial for a long time as these side effects were minimal and just became worse . I'm not on any other drug. I'll have to go off it but what's next??"

For Paroxysmal Supraventricular Tachycardia: "I have been on Flecainide for 3 months. It has totally eliminated my PSVT. I am on 100 mg twice a day. I have not noticed any side effects. I wonder if I should go through with the planned ablation."

For Atrial Fibrillation: "After ER episode for atrial fib (which I believe was one-time stress-induced issue) I was bullied into taking this med by hospital upon discharge. My job as a knowledge worker requires me to *think* for a living. I'm considered an expert in my field. This damn drug put me in a mental fog to the point that I stared at the computer screen wondering what I was looking at. My mood became aggressive, depressed and I felt increasingly isolated, listless, tired, but hard to sleep. I gained about 15 lb with no change in diet, in fact I probably ate less. I lost desire for my usual workout routine. After weaning off after 6 months, and now taking only daily aspirin, I'm back to my happy self, focussed and motivated. This is a bad drug, IMO."

For Atrial Fibrillation: "Life long history of slight double vision (1 diopter). Within 4 days of usage, developed severe increase of double vision (estimate 10-15 diopters). Ceased usage and symptoms decreased by half within 1 day. Now, 3 days later and recover continues but not fully back to ordinary."

For Atrial Fibrillation: "2008 A Fib diagnoses after 2 years of dizziness and feeling "odd"otherwise fit and healthy. 4 Cardio versions and 2 catheter ablations under my belt now. First Doc prescribed cardio version and Amiodorone , horrible side effects. Went to a Cardiologist that specializes in A Fib. Tried two ablations. Effective for a awhile but after last cardio version prescribed Flecainide. Still get breakthroughs for short durations but the strange feelings and emotional drain after incidences are the most debilitating. I just take a Klonopin and a nap. 100mg twice a day every 12 hours. 73 year old Female"

For Atrial Fibrillation: "Benign artrial fibrillation. Cardiologist tried everything -- next step was surgery. Was having from 10-15 six hour episodes per month and ruining quality of life. Have been on flecainide for 2 years and it is now completely under control. Only episodes I've had were a year ago during a bronchitis episode but as soon as antibiotics kicked in the a-fib was gone again. Absolutely no side effects and this medicine has changed my life."

For Supraventricular Tachycardia: "Following a knee replacement over two years ago I developed SVT...a runner for 35 years, I couldn't believe I had any issue with my heart. Hypertension, mainly due to heredity, but that is about all I can complain about. I lived with the problem for a year until 1/2016 when my doctor put me on metoprolol...this stuff was terrible. My heart rate would drop to below 50..or go higher than 90. Again I lived with this medication for a year until I thought about cardiac ablation. Before considering this method, my NEW Doctor prescribed flecainide. This was a game changer for me. Though I still have a "skip", I am functional and have much more energy and overall better wellness than I had not had for years."

For Atrial Fibrillation: "Flecainide has controlled the a-fib, but I have a constantly cold nose and my mouth feels like I've had lidocaine sprayed like before dental work. Some days it's worse than other days. I take 100 mg twice a day with 25mg metropolol. After two cardioversions, I'm willing to give flecainide a chance. I've been taking it for six months and hope the side effects don't get worse with time."

For Ventricular Tachycardia: "I was put on Flecainide several months ago. Side effects were fatigue, and dizziness. Effects were interfering with my life (had to pull over if driving and my commute to work is at least and hour each way). Fatigue was robbing me of being able to enjoy activities. I have stopped taking and am looking into other treatment options."

For Atrial Fibrillation: "I've been taking 50mg of flecainide twice a day for 2 years now and still love it. I have had no incidences of afib and no side effects. I do like my alcohol and have 1-2 drinks daily. I believe the flecainide keeps me from having an alcohol related episode which my doctor believes is my trigger. I agree with him but also think dehydration, dieting and stress have been contributing factors as well, and again, the flecainide overrides them all. I'm sure it's not perfect for everyone, but for me it's been a godsend."

For Atrial Fibrillation: "I've been on Flecainide for about 3 months. Before, I was having Afib everyday, usually at night for over a year. And even after taking other medications prior to Flecainide , it would take several hours before the Afib would go away. It was a terrible existence. Since taking Flecainide, I have had NO Afib. This to me has been remarkable. The side effects for me are mainly tiredness for a couple of hours after taking it. It might give me constipation but I really think that diet plays a greater role. Eating more fiber and veggies, and less meat is better for me. I have been taking Flecainide once in the early afternoon and then once usually an hour before bedtime, each time with 100 mg. I wonder if I can stop taking it in the future?"

For Atrial Fibrillation: "Three months ago, because of paroxysmal afib and after wearing an event monitor, I was put on both Flecainide (50 mg twice per day) and Metoprolol (50mg at night). The original dose was Flecainide 100 mg twice per day, but when I told the cardiologist that I didn't like the way it made me feel, he immediately said "Well OK, just take half the amount each time", as though the difference wasn't a big deal! The Flecainide seems to be working, but instead of feeling better I am feeling progressively worse by the day. Not sure whether Flecainide is to blame or the Metoprolol. Feel I'm in a dream most of the time, excessive daytime sleepiness, slight dizziness, memory problems, depression. Hard to get hold of cardiologist."

For Atrial Fibrillation: "Beware of this drug. My mother was put on this drug in addition to diltiazem. It sucked all the life out of her. She got tremors; couldn't walk 100 meters without catching a breath. Major fatigue and weight gain. If you're sensitive to meds, do not use this drug. She will stop this drug today."

For Atrial Fibrillation: "I had the first afib experience in 2004 (age 63)while playing senior softball, took shock paddles to convert. Kept playing sports and had second episode in 2007, converted with Amiodarone. Stayed on that until new doctor (insurance changed), took me off without a replacement, re-ocurrence couple months later, restarted on Amiodarone for conversion. Back with original doctor, kept up Amiodarone and all the blood work, x-rays, pulmonary function tests, etc. required semi-annual till 2014. Finally (after more tests) was switched to 100 mg. Flecanide & 12.5 mg. Metoprolol twice daily, with no semi-annual tests. So far-so good, except for some arthritis ? issues, still active in sports (senior). Hopefully this will stay with me."

For Supraventricular Tachycardia: "I am a reasonably well controlled insulin dependant diabetic. I was put onto flecainide as I was unable to have an atrial ablation and had reacted badly to both beta blockers and calcium blockers. Within 24 hrs of taking a dosage of 30 g , twice, I lost all control of my blood sugars. I stopped taking flecainide within 48 hrs of the start due to out of control blood reads ie excessively high. 2 days further down the line I still have no control of my blood sugars and have so trebled the amount of insulin I would normally take, eg 14 at breakfast to 8( plus an additional 8 units mid morning). 18 at lunch compared to a usual 8 units as examples. My diet has currently very little carbs in it as I attempt to get things back under control."

For Atrial Fibrillation: "After a number of inconvenient and stressful visits to ER where I had an injected dose of flecainide ( which put me back into sinus rhythm) my cardiologist prescribed me 200 mg of Flec tabs plus 50 mg of metropolol on going into AF. It works a treat reversing me in 1 to 3 hours but I'm hoping doesn't lead to some of the side effects described in other articles on the net."
