Ingestion of chlorantraniliprole formulation may be associated with transient, reversible cardiac conduction abnormalities such as sinus bradycardia and first-degree AV block.

May warrant ECG monitoring in chlorantraniliprole ingestion; leaves open causal cardiotoxicity pending controlled data.
Chlorantraniliprole poisoning is rarely reported in humans. A 25-year-old man developed sinus bradycardia and first-degree atrioventricular block after ingesting a chlorantraniliprole 18.5% suspension concentrate formulation. Laboratory investigations were unremarkable, and ECG abnormalities resolved within 72 h with supportive care. ECG monitoring may be warranted in similar presentations.

Sharma et al. (2026) conducted a case report in Chlorantraniliprole formulation poisoning (n=1). Chlorantraniliprole 18.5% suspension concentrate formulation was evaluated on Cardiac conduction abnormalities (sinus bradycardia and first-degree AV block). Ingestion of a chlorantraniliprole 18.5% suspension concentrate formulation was associated with transient sinus bradycardia and first-degree AV block that resolved within 72 hours.
