A member asked:

I'm on flecainide 50mg bid. my symptoms seem worse since i started the med 5 days ago. my doc wants me to increase dose 100mg bid. what do you think?

A doctor has provided 1 answer

Flecainide: We don't know enough about you out here to make a judgment. Without knowing more about you, why you're on flecainide and lots of other factors, about all we can say is. Flecainide 50mg BID is a low dose and 100mg BID is usually a lot more effective.....but dosing has to be judged by knowing the patient specific information.
