Management of Povidone-Iodine Ingestion

Initial Assessment and Management

For a 5-year-old child who has ingested 5 ml of povidone-iodine, observation without specific interventions is recommended as this small amount is unlikely to cause systemic toxicity, according to the American Academy of Pediatrics 1
The initial assessment should include confirmation of the amount ingested and the substance, as well as vital signs and a focused physical examination looking for signs of toxicity such as oral mucosa irritation, abdominal pain, signs of thyroid dysfunction, and mental status changes 1
Abdominal pain or tenderness, signs of thyroid dysfunction, and mental status changes are potential signs of toxicity that should be monitored 2

The child should be monitored for 2-4 hours in the emergency department for development of symptoms of iodine toxicity, including abdominal pain, loss of appetite, metallic taste, coughing, fever, diarrhea, and vomiting 1, 2
Laboratory tests such as thyroid function tests, serum electrolytes, and renal function may be considered for larger ingestions or symptomatic patients, as recommended by the Clinical Nutrition society 2, 3
Urinary iodine excretion measurement may also be considered if available 3

The child can be safely discharged if remaining asymptomatic after 2-4 hours of observation, and parents should be advised to return if any symptoms develop, particularly persistent vomiting, diarrhea, lethargy, or altered mental status 1, 2
Parents should be counseled on proper storage of household chemicals and medications out of children's reach, and childproof safety caps and locked cabinets should be recommended for all potentially harmful substances, as advised by the American Academy of Pediatrics 1
