I'm waiting for an ablation atm tried a number of different drugs to control my af this is the only successful one's, I've been shocked bk to rhythm 3 times so far and if I come off flecainide I don't want it to happen again its a catch 22, well that's if it is the flacanide causing the problems

Hi! No, you don’t sound crazy, but have you spoken to your Dr about this? Flecainide has a looong list of potential side effects! I get weird peripheral distortion (like a migraine aura) and I sometimes see a strange spider unlike any species in existence, which then disappears. Very unnerving! I’d love to get off this drug (on 50mg twice daily) as the other side effects are so debilitating. Good luck!
