propafenone dose

after 18 months amiodarone a cardio has put me on propafenone (Rytmomorm) at 150mg a day. Is anyone  taking so low a dose and is still keeping his/her heart steady?

No, and after the heavy duty Amiodarone.  

I have taken Propafenone at 225 mg three times a day and twice a day when I was in sinus following a couple of electrocardioversion.  If you're following me, the cardioversions were not purminate...one time I was in sinus for about 18 months the other time for two years.

As far as I know a dose of Propafenone once a day will not do much, as the medication will "wear off" quickly.  That's why I've taken as much as every 8 hours.

Rythmol does come in a slow release (SR), that my be fine once a day.  I've taken that too at the 425 mg level, but even then I took twice a day.  None of the medication on their own have stopped my arrhythmia problem.  My ER suggest a few months bak trying Amiodarone.  I said no.  

As it stands I am in AFig and living with it, taking warfarin and Toprol XL to keep HR down.

I took 200 amiodarone for six months before I stabilized at a pulse of 60. That was 14 months ago. In that time my heart beat  has never varied, no flips or tachys. I have now been on Propafenone 150/day for six weeks and so far  my pulse remains stable

The question remains: was it the amio that put my TSH up to 38? No way of verifying, I guess

Good to read you are in NSR.  I agree 150 mg Propafenone isn't much mediation, and its half-life is something like 8 hours I think.  Rhythmol SR (a 24 hour capsule) would seem to me to be better, but if it works great.

Propafenone has help hold me in NSR following electro-cardioversion, but then I was taking 225 mg Propafenone every 8 hours.  Did it work?  Who knows, I was in NSR for 18 months or so, then back to AFib.  See my bio, I had other problems aggravating my AFib.

I may try a stronger drug, such as you had.  

Your "TSH" lost me, I don't understand the abbreviation.
