Good to find people on this forum who are taking Flecainide as a PIP. Two years ago, following two failed ablations for AF I went into serious tachycardia and flutter for almost three days on the ward, despite all the drugs they could throw at it. So I had an AV node ablation and was fitted with a dual chamber pacemaker. At that stage, I elected to come off all the drugs, including Bisoprolol which I hated because of the fatigue it caused, and now take just take dabigatran daily which will be a lifetime drug. I also came off Flecainide which I had been taking regularly up to this point. Although this rather drastic procedure doesn't cure the AF, it certainly mitigated the symptoms to a point where I was able to forget all about it.
However, sometimes I now rarely get what I would call palpitations on exertion and my pulse becomes irregular. Understanding that a pacemaker will speed up a slow heartbeat but not slow a racing one, I took a dose of Flecainide by instinct and it settled within an hour. So I now carry it as a PIP. My GP says he has no objection to this, but he is no cardiologist and I wonder what attitude others have to taking Flecainide on an as and when required basis.
