My husband had a triple bypass and valve replacement surgery last June. He is 80 years old. He takes a variety of drugs, one of which is Amiodarone. He is frail, his weight is down to 129 and he is 5'7" tall. He has a problem of falling on occasion and so far has only suffered minor scrapes and bruises. Could the falling be a side effect of the Amiodarone? Or possibly another cause?
