Is acid reflux or Indigestion linked to Flecainide?

[AfibExpat]

Hi, everyone.  I have been taking Flecainide 2x per day for A-fib, for over 1 year now.

I have had acid reflux for about 20 years, but it has been under control for years and years thanks to a daily does of Prevacid.  But, about 4 months ago, my acid reflux suddenly got much, much worse.

Because I drink very little, exercise regularly and eat well, I began to wonder if the sudden worsening of my acid reflux were somehow connected to my Flecainide intake.  Has anyone heard of a linkk between Flecainide and acid reflux, indigestion or heartburn?

I have been taking flecainide 50 mg twice a day for only four days now for atrial fib.  I had been taking Multaq, but had an episode of AF and my doctor and I decided to try flecainide.  I have had heartburn for two days now, about 3:30 pm after having had the lunch I have had for a very long time....spinach salad, pbutter on whole wheat, brownie and yogurt.
I don't fine heartburn llisted as a side effect on any flecainide website.

I am wondering the exact same thing. I have also been on flecainide for about a year and am now experiencing terrible heartburn.

I have to eat something when I take my Flecainide or I get bad acid reflux. I take 150 mgs 2 x a day for V-Tach.
