Rain, my brother now has Parkinson's disease and is in assisted living. He was given amiodarone prior to having cardioversion. The only thing is, he slipped through the cracks and they never gave him the cardioversion! He was on this med for a yr and 4 mos. My nurse cousin and I kept telling the dr SOMETHING was wrong and he just said, when he gets better, we will look into his medicines!!! Well, DUH.............. When my brother begain having Parkinson symptoms, we even said so to the doctor (amiodarone can cause these side effects) and he ignored it. Finally after passing out all over town in stores, at home, etc., brother ended up yet again in local ER and the doctor here in town sent him to Pensacola instead of the hospital where he had been going to ER. A neurologist found the problem, took him off the medicine - and while in that hospital they did the cardioversion, by the way. Don't know if the amiodarone caused all of this Parkinson's or not, but it sure seemed to push it along and he is more or less helpless and must be taken care of by others. He is a lifelong bachelor, had a lovely bachelor pad home in deep woods, was enjoying his retirement and independence............
