I’m new to this forum, I found it while looking for information about side affects when stopping flecainide. I am having an ablation on the 10th of this month so in preparation have stopped the flecainide I’ve been taking for 13 yrs. Within 24hrs of stopping I’ve experienced nausea and lightheaded ness, probably just a coincidence. I am also in constant afib, which seems very normal to me and not a problem.
I’d be interested to hear from anyone who has experienced symptoms other than afib when stopping flecainide.

Hello Getoutside and welcome to the forum. Just want to clarify a couple of things if I may, are you stopping the Flecainide under guidance from your Doctor and did it keep you in sinus rhythm prior to stopping. In my case, I was taking a daily maintenance dose of 2 x 50 mg right up to the evening before my cryoablation and was asked by my EP to continue the dose for 6 months after the ablation. We are not medically trained therefore we will not make suggestions on medication but I just thought we should establish that these changes are as advised by your doctor.
My dose was the minimum used and I did not experience any side effects but ironically, I did have a short run of AF a couple of days after stopping the Flecainide.
Below are a couple of links to AF Association factsheets which you should find helpful. Hope all goes well and please let us know how you get on....
Yes I am making changes at the advice of my EP. I was on Flecainide 100mg 2x/day up until 18mos ago. Prior to that time flecainide completely controlled my afib. The dose was increased to 150mg 2x/day and since that time I average episodes on average 3hrs/ day, thus the decision to do the ablation.
Getoutside, I have a couple of questions on your post here. 1.) How long were you on the Flecainide 100 mg. 2 x day while the drug controlled your afib? 2.) Why was your dose increased to the 150 mg. 2 x day? Did the afib return 18 months ago? 3.) You say your episodes average 3 hours per day. How often do you now have those episodes? Thanks. I'm wondering because I just started having afib last summer and have had episodes maybe on the average of every 18 days and I have always converted on the next or the second day. Thanks and best of luck with your ablation.
Yes I have had 7 ablations. I am however, the the exception to the rule.
I had PAF every few weeks from about 1990 to 2017. Many episodes lasted more than a day and needed electrical cardioversion but I also was able to revert the majority to NSR with Flecainide “pill in a pocket”. I had my last ablation in August 2017.
In the time since August 2017 I have had only 3 episodes, each lasting about 3 - 5 hours.
The majority of ablations are successful first or second time and those patients either don’t look for this forum nor they don’t hang around in this forum.
Hi there.. I tried stopping flecainide after 5 years as advised by my EP 3 months post ablation, I had thumping headaches about 3 days on the bounce. I started taking a lower dose as the headaches were so bad and the headaches went so now I am just reducing the dosage every 2 weeks until it is zero. On 25mg x 1 now from 50mg x 2 originally.
I took 150mgs of flecainide twice daily and was told to reduce to 100mgs x 2 on the day of my ablation, then reduce to 50mgs x 2 after 6 weeks. I stopped completely on the day of the follow up appointment which was about 4 months after the ablation. I didn't notice any problem.
Two weeks and a day since I was told to stop taking the 2 X 100 mgs of Flecainide having been on it for two and half months. As far as I can tell the only noticeable possible effect is I am getting regular ectopics but anticipate that may well diminish over the next few months
I just stopped taking Flecainide after having taken it for twelve years. I was taking 100mg 2x daily. I did taper off, as I wanted to see what the lowest dosage was, that would keep me out of afib. I stopped at 50mg twice daily. The only side effects I have noticed since I stopped, are the Ectopics are back and the last three nights I have had short episodes of Afib. It has been a week since I stopped. I had been told to switch to PIP 200mg if I had an episode. Since these happened three nights in a row, I decided to sit them out, and see how long they lasted. Last night it was an hour, and then it tapered off. So have not yet used PIP. Doctor told me it is more important how I feel, than what he tells me to do. I do not want to be doing PIP every time I feel a little flip flop. The only real side affect I have noticed is, that the weird off balance feeling I have had for some time, stopped with the Flecainide.
