Amiodarone lung toxicity

Amiodarone is an effective medication that was created for management of cardiac arrhythmias. It is sad to note though that it is also a potentially toxic antiarrhythmic drug and can be a challenge to use safely.

The usual side effects of amiodarone include corneal deposits, thyroid ailments, liver issues, photosensitivity and bluish discoloration of the skin.

Due to its potential to trigger various forms of toxicity, the doctor only prescribes amiodarone for individuals with dangerous or severely debilitating arrhythmias and there are no available treatment options. Remember that the most serious side effect is pulmonary toxicity.
