Pregabalin intoxication-induced Prolonged PR Interval on Electrocardiogram

Pregabalin is a lipophilic analogue of gamma-aminobutyric acid (GABA) and has a similar chemical structure to gabapentin and is more potent than gabapentin. This report documents the case of a 28-year-old male presenting with suicidal attempt by pregabalin intake. The patient had an abnormal PR interval (reversible AV-block). He was managed with general supportive care and symptomatic approach such as discontinuation of the drug, hydration with IV fluids, oxygenation, gastric lavage and activated charcoal administration.
