Oleander poisoning: Two cases with contrasting cardiac presentations

Oleander is an imported ornamental shrub occurring across the majority Australia with two main species Nerium oleander (common or pink oleander) and Cascabela thevetia (yellow oleander) seen. Oleander is a highly toxic plant containing cardiac glycosides that can lead to life-threatening cardiac and gastrointestinal complications. All parts of the plant are toxic. Accidental and intentional ingestion of the plant is reported throughout the world involving both humans and animals. Published case reports from Australia are historical and do not reflect current conventional management. This case report details the intentional ingestion of oleander leaves as a food source and the differing presentations of two family members. The report describes the presentation, diagnosis, and successful management of both patients. This report aims to enhance awareness among healthcare professionals regarding the clinical features, diagnosis, and current treatment of oleander toxicity especially in the pre-hospital and emergency settings.
