I fainted recently. my Dr. said it was due to hyponatremia (low salt in my blood). I've read since then that Flecainide can cause this: "Hyponatremia is a previously unrecognized entity as an adverse effect of flecainide...
By this rationale, hyponatraemia would lead to Flecainide toxicity. Flecainide has been shown to reduce salt absorption in animal bowel."
has anyone else experienced this as a side effect?
I was doing 100mg twice a day as directed by my original DR who performed an ablation on me three years ago. recently, I've cut it down to 50mg x 2 with no recurrence of afib symptoms. they did return when I tried to quit completely.
I also read: "Excessive mortality or nonfatal cardiac arrest rate was seen in patients with asymptomatic nonlife-threatening ventricular arrhythmias and myocardial infarction more than six days but less than two years previously who received flecainide compared with patients assigned to a carefully matched placebo in the Cardiac Arrhythmia Suppression Trial (CAST). It is prudent to consider the risks of Class IC agents (including flecainide), coupled with the lack of any evidence of improved survival, generally unacceptable in a patient without life-threatening ventricular arrhythmias, even if the patient is experiencing unpleasant, but not life-threatening, symptoms or signs. Flecainide is not recommended for use in patients with chronic atrial fibrillation. Case reports of ventricular proarrhythmic effects in patients treated with flecainide for atrial fibrillation/flutter have included increased PVCs, VT, ventricular fibrillation (VF), and death."
can anyone recommend a drug they've been on that's considered safer and that works? THANKS!
