I have been taking Flecainide for 2 years and am now having frequent runs of tachycardia which my cardiologist says is Atrial Flutter caused by Flecainide changing AF signals into AFlutter. I have no AF - just short runs of rapid, regular beats of 130bpm now coming almost daily.
My EP is aware of these runs which happened only a couple of times in 18 months to start with and described them as not a separate arrhythmia but the result of taking Flecainide. I am now waiting to see my EP again and really fear that anti-arrhythmic drugs all may have the same effect - so I'm feeling a bit long in the face today.
Has anyone had this side effect from Flecainide and how was it resolved?

I was prescribed Propafenone and took it for several years very successfully but eventually I had an attack (not exaggerating!) of AF which morphed into tachycardia. Then Diltiazem was added but I began to have a very slow HB and long pauses so I was given an ablation for AF and Flutter. I'm not on any meds now though I still have some funny blips and runs which I am ignoring.....💜
Good news in the end - long may it continue. Can hardly get a breath today as heart thinks it is in the Rio gymnastic team - thank you for sharing your experience.
I have had a few minor incidents ( pulse never over 110) of this. When I had two runs of this on the same day , I saw a GP( not mine but very good) who added in 1.25mg Bisoprolol as 2.5 had dropped my pulse too much when I first had AF and was stopped. He also suggested I might be able to reduce flecainide dose which I discussed with my own GP a couple of weeks later and am now on 50mg flecainide in the morning and 100mg at night. So far so good.
That's good news Bagrat - I hope it works well for you. The runs of tach became more frequent when I reduced from 200mg to 150mg daily over a period of 6 weeks. Then they progressed to 3 a week, so I was advised to go back up to 200mg daily and since then, they are even more frequent. No logic or sense to it but at least it's not coming through as AF.
Last summer after being on flecanide for five years, it was discovered that I had flutter as well as AF (thanks to my GP). I presumed this was down to flecanide although no one said so. I saw a EP which was the first time I had seen a Dr apart from my GP and he suggested an ablation. My GP had sent me back to the hospital about three years previously, but i was told by the nurse that there was nothing that could be done for me. I know that I was no where as bad as some people , but feel that I was allowed to get worse over the years.
I had hybrid ablation at the end of last year and so far so good. Came off flecanide five weeks ago.
Thank you robin - a nurse deciding that no treatment could be offered was not very helpful for you and I'm glad that things have now worked out so well.
It's really useful to have other people's experiences to compare in trying to decide where to go from here.
Doctor just switched me off of flecainide . Second ablation was last December and no AF and no meds other than my xarelto since Feb. however after a trip to the dentist having a tooth pulled and them using a product with epinephrine in July I was having AF episodes...flecainide isn't working and in my opinion I think I am getting flutters from it. Yesterday of course they didn't catch anything on the EKG but I explained I know the feeling...
He gave me propafenone , will see how that works.took first pill last nite, I slept wonderfully.
