Can someone consume alcohol while taking flecainide?

Possibly: Alcohol can depress heart function (lead to congestive heart failure) and that combined with Flecainide makes for a dangerous situation. In general, as alcohol affects the liver and Flecainide is cleared through the liver, it is not a good idea to combine heavy alcohol use with flecainide. However, combining low amounts of alcohol and Flecainide may not be a problem.

Should not: Flecainide is used for heart rhythm disturbances, many of which can be caused by alcohol. Alcohol, especially when taken regularly in even moderate doses (2-3 drinks/day) can actually damage the heart muscle in predisposed people. It also has numerous drug interactions, and can lower therapeutic levels of many drugs. You need to talk with your doctor about your alcohol use.
