Cardiac rhythms and yellow petals: A rare case report on yellow oleander poisoning presenting with hypomagnaesemia

This case report presents a 29-year-old female who intentionally ingested three yellow oleander ( Thevetia peruviana ) seeds, resulting in acute cardiac glycoside toxicity. The patient presented with gastrointestinal and cardiovascular symptoms, including persistent vomiting, chest discomfort and bradycardia. Notably, the patient also exhibited hypomagnaesemia, an electrolyte disturbance not commonly highlighted in oleander poisoning cases. Through prompt supportive care, careful monitoring and electrolyte management, the patient recovered without the need for digoxin-specific antibody fragments. This case highlights the importance of recognising and managing oleander poisoning, a potentially life-threatening condition that mimics digitalis toxicity, while also emphasising the role of magnesium in cardiac function.
