Prednisone & Prednisolone Pediatric Dose — Steroids
Prednisone and prednisolone are corticosteroids that exert anti-inflammatory and immunosuppressive effects by binding glucocorticoid receptors and suppressing cytokine-mediated inflammatory cascades. Prednisolone is the active form and is often preferred in younger children due to better oral bioavailability and available liquid formulations. These agents are widely used in pediatrics for conditions including asthma exacerbations, croup, allergic reactions, and inflammatory disorders.
Pediatric Dosing
- Dose: 1–2 mg/kg/day PO, divided every 12–24 hours
- Usual adult maximum: 60 mg/day
The appropriate dose within the 1–2 mg/kg/day range depends on the severity of the condition and the specific indication. Consult institutional protocol for indication-specific dosing durations and taper schedules.
Worked example: For a 15 kg child at 1 mg/kg/day: 15 × 1 mg/kg = 15 mg/day (may be given as a single daily dose or divided every 12 hours as 7.5 mg per dose). At 2 mg/kg/day: 15 × 2 mg/kg = 30 mg/day.
Indications and Clinical Context
Prednisone and prednisolone are used across a broad range of pediatric inflammatory and immune-mediated conditions. Common acute indications include moderate-to-severe asthma exacerbations, croup with moderate-to-severe stridor, and anaphylaxis as an adjunct to epinephrine. Chronic and subacute indications include nephrotic syndrome, inflammatory bowel disease, and rheumatologic conditions. In the setting of asthma exacerbations, systemic corticosteroids are recommended by GINA and PALS-aligned guidelines to reduce airway inflammation and decrease the risk of relapse.
The choice between prednisone and prednisolone is primarily one of formulation and patient factors; prednisolone requires no hepatic conversion and is preferred in patients with hepatic impairment or very young children who benefit from a liquid preparation.
Administration and Monitoring
Both agents are administered orally. Prednisolone is available as a solution and orally disintegrating tablet, which may improve adherence in younger children. Doses may be given once daily or divided every 12 hours depending on indication and tolerability. Administration with food can reduce gastrointestinal upset.
- Route: Oral (PO) only per this dosing description
- Max dose: Usual adult maximum of 60 mg/day; consult institutional protocol for weight-based caps in children
- Adverse effects to monitor: Hyperglycemia, hypertension, mood changes, insomnia, and gastrointestinal irritation with short courses; growth suppression, adrenal suppression, and immunosuppression with prolonged use
- Contraindications: Systemic fungal infections; use with caution in patients with active infections, uncontrolled diabetes, or peptic ulcer disease
- Taper may be required for courses exceeding 7–10 days to avoid adrenal suppression; consult institutional protocol
