Hi Thanks for choosing HCM for your query. I appreciate your concern towards the safety of Amiodarone. Since Amiodarone is most commonly used in the treatment of life threatening heart arrhythmias and the fact that you have developed some of its important side effects like lung fibrosis, thyroid disease, skin pigmentation, etc hence an alternate drug is needed. There are other options but you are advised to discuss this with your treating doctor as he is aware of your medical history and diagnosis. Dronaderone is very much like Amiodarone in its efficacy but with less side effects. The drug is also non-iodinated and thus causes little anti-thyroid effect. Hence the drug may provide the benefits of Amiodarone without the toxicity profile. Hope the suggestion given above could be useful to in getting the alternate drug to Amiodarone. A feed back is appreciated.
