Too Little, Too Late: A Case of a Swift Fatal Culmination of Amiodarone Induced Pulmonary Toxicity in an Adult Male

Abstract

Amiodarone is a commonly prescribed antiarrhythmic drug. It can cause a myriad of complications associated with its long-term use, with amiodarone induced pulmonary toxicity being the worst. Amiodarone does this through its destructive properties and its’ ability to accumulate if taken for extended periods of time or in high cumulative doses. Albeit uncommon, the management of amiodarone induced pulmonary toxicity can be straightforward if recognized early. Otherwise, it can lead to severe respiratory failure causing death. In this case report, we aim to highlight the importance of vigilance with clinicians prescribing amiodarone and to spark interests into research for alternative management options of amiodarone induced pulmonary toxicity. This will be done through the description of a case of a 64-year-old male presenting with cough and dyspnoea, who has been on a large dose of amiodarone daily for the past 11 months. He was diagnosed too little, too late, which unfortunately culminated in his rapid fatality. This case is unique for two reasons. The diagnosis of amiodarone induced pulmonary toxicity was through the clinical picture – without the use of invasive investigations. In addition, the futile cessation of amiodarone and use of high dose systemic corticosteroids as a management – which to our knowledge is uncommon in literature.
