Abstract
Within hours of accidental instillation of a popular diaper rash protector spray, a 23 day old male developed severe chemical pneumonitis, acute respiratory failure and pneumomediastinum. Despite optimal ventilatory management, the unconventional use of frequent bronchial saline lavages was necessary to maintain oxygenation and ventilation. The only listed active ingredient, 10% dimethicone was a non-toxic inhalant, but the undisclosed inactive ingredients included mineral oil and balsam of peru which may cause chemical pneumonitis and allergic reactions. This case serves as a warning on OTC product designs and formulations, and cautions us to search beyond the listed active ingredients for potential toxicity.
