It's everyone's least favorite drug because of its nasty side effect profile, and yet it still gets widely used, particularly in elderly patients because nothing else works nearly as well for many types of arrhythmias. Regularly kills patients via pulmonary toxicity. That just happened to the elderly mother of a doctor I know.
On a sad note, a leading cardiac surgeon at a Boston hospital recently got shot and killed by a nut who was convinced his mother died because of amiodarone the surgeon had prescribed.
Likely not a significant overlap with the treated HCV population.
