Benzonatate is a commonly prescribed antitussive with rapid and deadly effects in overdose. We report a 14-year-old female who ingested 14 capsules containing 200 mg benzonatate. Her case represents the only reported benzonatate overdose with torsades de pointes, as well as the only reported pediatric benzonatate ingestion complicated by cardiac arrest with full recovery.
