PY - 2014 T2 - Strange and Schafermeyer's Pediatric Emergency Medicine, 4e AB - Acute ingestions are generally benign but may be delayed in onset (2–4 days).Ingestions of greater than 5 mg warrant measurement of T4 concentration at about 4 hours after ingestion. A T4 level of greater than 75 mcg/dL warrants close follow-up such as daily assessment for signs and symptoms of thyroid hormone excess.Symptoms are usually mild and consist of adrenergic excess: tachycardia, hypertension, fever.Treatment is symptomatic and may include beta-blocking agents and antipyretics.
