Amiodarone is an antiarrhythmic medication used to treat and prevent a number of types of cardiac dysrhythmias.[4] This includes ventricular tachycardia, ventricular fibrillation, and wide complex tachycardia, atrial fibrillation, and paroxysmal supraventricular tachycardia.[4] Evidence in cardiac arrest, however, is poor.[5] It can be given by mouth, intravenously, or intraosseously.[4] When used by mouth, it can take a few weeks for effects to begin.[4][6]

Common side effects include feeling tired, tremor, nausea, and constipation.[4] As amiodarone can have serious side effects, it is mainly recommended only for significant ventricular arrhythmias.[4] Serious side effects include lung toxicity[7] such as interstitial pneumonitis, liver problems, heart arrhythmias, vision problems, thyroid problems, and death.[4] If taken during pregnancy or breastfeeding it can cause problems in the fetus or the infant.[4] It is a class III antiarrhythmic medication.[4] It works partly by increasing the time before a heart cell can contract again.[4][6]

Amiodarone was first made in 1961 and came into medical use in 1962 for chest pain believed to be related to the heart.[8] It was pulled from the market in 1967 due to side effects.[9] In 1974 it was found to be useful for arrhythmias and reintroduced.[9] It is on the World Health Organization's List of Essential Medicines.[10] It is available as a generic medication.[4] In 2021, it was the 235th most commonly prescribed medication in the United States, with more than 1 million prescriptions.[11][12][6]
