Amiodarone-Induced Immune Thrombocytopenia: A Rare Hematologic Side Effect of a Common Cardiac Drug

Thrombocytopenia is a rare immune-mediated hematologic complication of amiodarone. We describe a case of delayed-onset amiodarone-induced thrombocytopenia in a 72-year-old male and highlight the process of working it up. A timely diagnosis of drug-induced immune thrombocytopenia is crucial in order to minimize unnecessary testing, avoid treatments with potential harm, and prevent life-threatening hemorrhagic complications.
