Dexamethasone Oral Dosing for Pediatric Patients

Standard Dosing by Indication

The standard dose of dexamethasone for most pediatric conditions, including bacterial meningitis and cerebellitis, is 0.15 mg/kg orally every 6 hours for 2-4 days, as recommended by the Infectious Diseases Society of America 1, 2

For bacterial meningitis, the dose is 0.15 mg/kg orally or IV every 6 hours for 2-4 days, and must be initiated 10-20 minutes prior to, or at least concomitant with, the first antimicrobial dose, as recommended by the Infectious Diseases Society of America 1, 2
For cerebellitis, the dose is 0.15 mg/kg orally every 6 hours for 2-4 days, and a single short course does not cause clinically significant adrenal suppression, according to the American Academy of Pediatrics 3

For neonates and preterm infants, high-dose dexamethasone (≥0.5 mg/kg/day) should be avoided due to risk of gastrointestinal perforation, hypertension, hyperglycemia, and impaired growth, as recommended by the American Academy of Pediatrics 5

The use of dexamethasone is not recommended for streptococcal pharyngitis, and acetaminophen or NSAIDs should be used for symptom management instead, as recommended by the Infectious Diseases Society of America 6
Dexamethasone is ineffective in bacterial meningitis if given after antimicrobial therapy has begun, as recommended by the Infectious Diseases Society of America 1, 2
Neurodevelopmental impairment can occur with high doses (≥0.5 mg/kg/day) of dexamethasone in neonates, as reported by the American Academy of Pediatrics 5
