Amiodarone is classified as a class III antiarrhythmic agent for both atrial and ventricular arrhythmias. Amiodarone has been found to be associated with variety of adverse effects in some case report. The most serious of those is pulmonary toxicity, which may even cause acute respiratory distress syndrome (ARDS), and ensued fatality rate is close to 50 percent. We presented a case had pulmonary toxicity and dyspnea symptoms whom received long-term low dose amiodarone (200mg per day). The literature reviews offer the theorized pathophysiology, therapeutics and monitor recommendations of amiodarone induced pulmonary toxicity to find adverse reaction earlier
