I have not had a single episode of AF since I started taking 50mg Flecainide x 2 daily in October 2012. Now my blood tests show borderlline neutropenia (low white blood cell (WBC) count) and I see this is a known possible side effect of Flecainide. I tried twice stopping Flec. but each time my HR became irregular after about 4 days. I am wondering if taking Flec. every other day might allow my WBC to recover while keeping AF at bay. I'd appreciate any comments.
