I've been taking propafenone for a week now 150mg twice a day for constant extrasystole (18000 in 24 hours according to my holter results), it's been a nightmare. I was already taking 50 mg of Metoprolol due to the same issues during pregnancy (200mg while pregnant and lowered to 50mg as soon as baby was born 4 monts ago), everything was fine until last week when arrythmia restarted. Cardiologist increased dose today to 150mg 3 times a day, but every time I take it I feel weird and tired, side effects have given me anxiety and have gone to the ER 3 times in 5 days and instead of something going wrong, my EKG seems to be improving.
Has someone experienced uncomfortable side effects? Will they eventually fade out? Anxiety is making me crazy.

I took Propafenone 150mgs three a day for 2 months, with no side effects apart from the commonly reported metallic taste. That did not go away.
You must be having a tough time. It sounds like the Propafenone is helping with the ectopics, but you must be wondering about switching back to an increased dose of the Metoprolol.
Exactly, specially tonight, the arrythmia seems to be back even with the third dose.. he gave me an option to switch from propafenone to 200mg of Metoprolol since I already tolerated in the past, but I'm really scared.. don't know what is best for me.
Only you and your doctors know that. When you say arrhythmia, do you mean ectopics? I’m not a medic, but I thought atrial ectopics were uncomfortable but not dangerous, though some people have ectopics before going in to AF apparently.
I hope it is not inappropriate to ask, but are you nursing your infant? If so, is there a problem with Propafenone getting in to the milk?
I took much more than that (900mg a day) for many years with zero problems apart from the taste issue. I feel weird and tired when not taking any drugs. Thought that was life. lol

I just read the first discussions of this year and I'd like to ask Koll and others of propafenone 
Too much propafenone?
Anyone out there on Propafenone? 
Propafenone and Carvedilol
