Tesfaw 1  \nAbstract  \nBackground Amitriptyline, a classic tricyclic antidepressant, can produce toxic effects ranging from mild antimuscarinic symptoms to severe cardiotoxicity due to sodium channel blockade. In severe cases, toxicity may rapidly progress to cardiac arrest if not promptly recognized and managed.  \nCase presentation We present a 25-year-old man who attempted suicide by ingesting 3.25 g of amitriptyline. He developed two episodes of cardiac arrest and recurrent life-threatening arrhythmias but was resuscitated and later discharged without neurological deficits. Management included aggressive supportive care, administration of sodium bicarbonate as the main antidotal therapy, and prolonged resuscitative efforts in the intensive care unit.  \nConclusion This case highlights that survival with good neurological outcome is possible even after multiple toxin-induced cardiac arrests when timely and persistent resuscitative measures are undertaken. It emphasizes the importance of early recognition of tricyclic antidepressant toxicity, prompt initiation of specific therapy, and preparedness for cardiac complications—particularly in low-resource settings. In addition, this report draws attention to the public health concern related to the accessibility and misuse of tricyclic antidepressants.  \nKeywords Severe amitriptyline toxicity, Multiple cardiac arrest, ACLS, Refractory arrhythmias, Sodium bicarbonate  \n*Correspondence:  \nAmanuel Dagabas Wakoya  \n[amanidag1246@gmail.com](amanidag1246@gmail.com)  \n1Department of Emergency and Critical Care Medicine, Haramaya university, Harar, Ethiopia  \n2School of Nursing, Haramaya university, Harar, Ethiopia  \n3Department of Emergency Medicine and Critical Care, Worabe Comprehensive Specialized Hospital, Werabe University, Central Ethiopia, Ethiopia  \nIntroduction  \nAmitriptyline is a tricyclic antidepressant (TCA) belonging to the class of tertiary amine compounds. Introduced in the 1950s, tricyclic antidepressants were among the first generation of drugs developed for the treatment of depression. However, their use has markedly declined over the years with the advent of safer and more selective antidepressants. Despite this, TCAs remain clinically relevant, both for depression and certain chronic pain syndromes. Tricyclic antidepressants are associated with a high risk of toxicity, exhibiting the highest ratio of deaths to exposures among antidepressant overdoses reported to U.S. Poison Control Centers [1].
