Hydrocortisone Pediatric Dose — Steroids & Stress Dosing
Hydrocortisone is a short-acting glucocorticoid with both glucocorticoid and mineralocorticoid activity, acting primarily by binding intracellular steroid receptors to modulate gene transcription and suppress inflammatory pathways. In pediatric practice, it is most commonly used to provide physiologic corticosteroid replacement during periods of acute physiologic stress in patients with known or suspected adrenal insufficiency. It is considered the preferred corticosteroid for stress dosing in children due to its balanced receptor activity profile.
Pediatric Dosing
Stress Dose (IV)
- BSA-based: 50 mg/m²/day IV divided every 6 hours
- Weight-based: 1 mg/kg/dose IV every 6 hours
- Patients on chronic corticosteroids: May use 2–4 times the home corticosteroid dose for stress dosing (consult institutional protocol for equivalent conversion).
Adult stress dose reference: 100 mg IV.
Worked example (weight-based): For a 10 kg child: 10 kg × 1 mg/kg/dose = 10 mg IV every 6 hours. For a 20 kg child: 20 kg × 1 mg/kg/dose = 20 mg IV every 6 hours.
Indications and Clinical Context
Stress-dose hydrocortisone is indicated in pediatric patients with known or suspected primary or secondary adrenal insufficiency who are experiencing significant physiologic stress, such as acute illness, surgery, trauma, or hemodynamic instability. In these patients, endogenous cortisol production may be insufficient to mount an appropriate stress response, placing them at risk for adrenal crisis. Common underlying conditions include congenital adrenal hyperplasia (CAH), hypopituitarism, and chronic exogenous steroid use with hypothalamic-pituitary-adrenal (HPA) axis suppression.
Stress dosing is a well-established practice supported by endocrinology and critical care guidelines. In the PICU setting, hydrocortisone may additionally be used for vasopressor-refractory septic shock in the context of relative adrenal insufficiency, though dosing for that indication should follow current institutional and Surviving Sepsis Campaign guidance, which may differ from the stress doses described here.
Administration and Monitoring
Hydrocortisone stress doses are administered intravenously (IV) as intermittent boluses every 6 hours. In emergent settings where IV access is unavailable, consult institutional protocol for IM administration options. The duration of stress dosing is typically guided by the clinical course; doses are generally tapered back to baseline maintenance or home doses as the stressor resolves. For patients on chronic steroid regimens, the 2–4× home-dose approach should account for the corticosteroid equivalency of the existing agent.
- Route: IV preferred; IM may be considered if IV access is unavailable (consult institutional protocol)
- Monitoring: Blood glucose (risk of hyperglycemia), blood pressure, electrolytes (sodium, potassium), and signs of fluid retention
- Contraindications/Cautions: Systemic fungal infections without concurrent antifungal therapy; use with caution in patients with diabetes or known immunocompromise
- Max single dose: Not explicitly defined in source; adult reference dose is 100 mg — consult institutional protocol for pediatric weight-based upper limits
