it is not a really big deal. Very common, lots of
data available, fairly few side effects
... There are other meds which you don't go into so lightly. Flecainide, sotolal, tikosyn, amiodarone... When I see some of
these on my pt list of
meds, it screams there is a problem- that simpler solutions couldn't fix. If you haven't tried the simpler ones yet, it is definitely a better place to start.
