Overdose in Infant Caused by Over-the-Counter Cough Medicine

Each year consumers purchase about 95 million units of over-the-counter medications for pediatric use, an unsafe application that can cause life-threatening effects. Despite a warning from the Food and Drug Administration, many parents or caregivers continue to administer these remedies to children. This report describes the case of a 4-month-old infant presenting to the emergency department with acute life-threatening intoxication including altered mental Status, impaired coordination of movements, as well as a positive urine drug test for phencyclidine and an elevated serum ethanol level. Further evaluation uncovered that the actual reason for all clinical symptoms and laboratory test results was over-the-counter cough syrup.
