Hi Ruth
What you are on is a loading dose which then decreases - when I was in AF after my op I was on IV Amiodorone for 48 hours, then onto oral. 2 x 200mg three times a day for one week, gradually decreasing over the month that I was on it.
While I agree with what others in this thread have said about it not being a very nice drug to be on (what drug ever is

??) I think that you have to just go with your cardio's recommendation and put up with it for the short time you will be on it. Every doctor I have discussed it with has said that they believe that it is well documented that it is probably the most effective drug available to convert AF back to sinus rhythm.
I myself have been on Amiodarone for short periods in the past, then back to Sotalol once back in sinus.....the doctors over here never leave people on it for prolonged periods because of the potential side effects (remember also that not everyone has the side effects).
Some doctors over here actually prefer Flecainide - anyone have any thoughts on that drug?
Also Ruth, direct current cardioversion is not as bad as it sounds - I was rapt to be back in sinus, and was asleep throughout the procedure anyway - woke up feeling like a new woman
Those are just a few thoughts of mine - you will get through this hiccup for sure. All the best.
