Flecainide toxicity

Arch Dis Child. 1989 Jun;64(6):860-2. doi: 10.1136/adc.64.6.860.


Flecainide toxicity occurred in an infant being treated for refractory atrioventricular re-entry tachycardia. Ventricular tachycardia developed when dextrose was substituted for milk feeds. We believe that milk was interfering with the absorption of flecainide, and so a high serum concentration developed when milk feeds were stopped.
