Loperamide-Induced Ventricular Arrhythmia and Seizures.
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLoperamide-induced cardiotoxicity can occur when taken at high doses. CASE SUMMARY: A 42-year-old man presented with polymorphic ventricular tachycardia after taking 100 to 200 mg of loperamide daily to self-treat opioid withdrawal. The presenting electrocardiogram showed a wide complex rhythm which spontaneously converted to sinus rhythm with a prolonged QT interval. Implantable cardiac-defibrillator therapies treated polymorphic ventricular tachycardia and ventricular fibrillation. Loperamide was discontinued, and he was treated for opioid use disorder. DISCUSSION: Loperamide can cause cardiotoxic manifestations such as acquired long QT syndrome with associated ventricular arrhythmias and neurologic manifestations such as seizures. TAKE-HOME MESSAGE: Although loperamide is an over-the-counter medication, life threatening cardiotoxicity and neurotoxicity can occur with high doses.
