Ibogaine

Cardiac arrest after ibogaine intoxication

A 61‑year‑old man developed massive QT prolongation after ingesting a very large ibogaine dose (65–70 mg/kg), progressing to ventricular flutter at 270 bpm and near‑fatal cardiac arrest requiring defibrillation. This represents the highest survived ibogaine dose reported, with the QT interval taking seven days to normalise due to the drug’s long half‑life.

Abstract

Ibogaine is a psychoactive herbal medication with alleged antiaddiction properties. We report a case of ibogaine intoxication mimicking Long‐QT syndrome resulting in ventricular flutter and nearby cardiac arrest. A 61‐year‐old man experienced massive QT prolongation and ventricular flutter at a rate of 270 beats per minute requiring defibrillation after ingestion of a large dose of Ibogaine. The ingested dose of 65‐70 mg/kg represents the highest survived ibogaine dose reported to date. As a result of the long plasma half‐life of ibogaine, it took 7 days for the patient's QT interval to normalize.

Research Summary of 'Cardiac arrest after ibogaine intoxication'

Introduction

Drug-induced prolongation of the QT interval on the electrocardiogram can precipitate life‑threatening ventricular arrhythmias and is an important consideration when evaluating unexplained torsades de pointes or ventricular fibrillation. The introduction frames ibogaine, a psychoactive plant alkaloid used informally for its alleged antiaddiction effects, as a potential cause of such cardiotoxicity. Steinberg and colleagues present a single case that illustrates severe QT prolongation after ibogaine ingestion leading to malignant ventricular arrhythmia and near cardiac arrest. The report aims to document the clinical course, emphasise the delayed recovery of QT interval related to the drug's pharmacology, and highlight safety concerns around unsupervised use.
