Abstract
INTRODUCTION: The purpose of this study is to evaluate the clinical presentation of accidental dextromethorphan (DXM) ingestions in children or =23 months). All cases co-ingested other products of over-the-counter cough and cold medications (i.e., acetaminophen, pseudoephedrine, guaifenesin, ibuprofen, various H1 receptor antagonists, and very infrequently ethanol). The mean DXM dose ingested was 35.0 mg (2.64 mg/kg). Of the patients, 62 (20.4%) experienced lethargy as the sole neurological sign and no patient had any cardiovascular abnormalities. Only 1 (13-monthold) patient, who ingested 3.2 mg/kg and presented with lethargy, was hospitalized and subsequently discharged 14 hours later. No deaths were recorded. CONCLUSION: As demonstrated in our patient population, accidental ingestions of DXM in the pediatric patient did well with supportive care alone and rarely required inpatient treatment.
