Prednisone & Prednisolone Pediatric Dose — Asthma
Prednisone and prednisolone are synthetic corticosteroids that exert potent anti-inflammatory effects by suppressing cytokine release, reducing airway edema, and restoring beta-agonist responsiveness. They are cornerstone agents in the management of acute asthma exacerbations and short-course “burst” therapy in pediatric patients. Prednisolone is generally preferred in younger children due to availability of liquid formulations and does not require hepatic conversion, unlike prednisone.
Pediatric Dosing
- Dose: 1–2 mg/kg/day PO, divided every 12–24 hours
- Maximum dose: 60 mg/day for asthma
- Route: Oral (PO)
The dose range of 1–2 mg/kg/day allows titration based on exacerbation severity. Once-daily dosing (every 24 hours) is often used for mild-to-moderate exacerbations, while twice-daily (every 12 hours) may be appropriate for more severe presentations. Course duration is typically 3–5 days; consult institutional protocol for specific course length.
Worked example: For a 20 kg child at 1 mg/kg/day: 20 × 1 mg/kg = 20 mg/day once daily. At 2 mg/kg/day: 20 × 2 mg/kg = 40 mg/day, given as 20 mg every 12 hours. The daily maximum of 60 mg/day would cap dosing for children ≥30 kg at the higher end of the range.
Indications and Clinical Context
Oral corticosteroids are indicated for moderate-to-severe acute asthma exacerbations and may be used as early step-up therapy in mild exacerbations not responding adequately to short-acting bronchodilators. Per PALS and NAEPP guidelines, systemic corticosteroids accelerate resolution of airway inflammation, reduce hospitalization rates, and decrease the risk of relapse following an acute episode. Early administration — ideally within the first hour of emergency presentation — is associated with improved outcomes.
Prednisone/prednisolone burst therapy is also employed in step-up management of recurrent wheezing or poorly controlled persistent asthma. Both agents are considered therapeutically equivalent at equipotent doses in the oral route.
Administration and Monitoring
Both agents are administered orally. Prednisolone liquid formulations (e.g., 15 mg/5 mL) are well-suited for infants and young children who cannot swallow tablets. Prednisone tablets may be used in older children and adolescents. Short courses of 3–5 days generally do not require a taper; consult institutional protocol for courses exceeding 5–7 days.
- Monitor: Blood glucose (especially in diabetic patients or those on concurrent medications), blood pressure, and behavioral changes
- Adverse effects: Short courses are generally well tolerated; may cause hyperglycemia, mood changes, increased appetite, and GI upset
- Administer with food to reduce GI irritation
- Maximum daily dose: 60 mg/day for asthma — do not exceed regardless of weight
- Use with caution in patients with active varicella or known immunosuppression; consult institutional protocol
