I was started on Amiodarone to convert me out of AF. 800 mg/day for three days converted me. Was given a green light to halve it but began waking up at 4 am with a bad headache and other side effects. Was told to stop for a day or so and then halve it again, but I took another day off. Today, went back into AF. Will call my EP tomorrow to see what they recommend. Has anyone upped their dosage again to convert back? Is that an option?
