At what age can prednisolone be started in pediatric patients?

Starting Age for Prednisolone in Pediatric Patients

Prednisolone can be started in infants as young as 1 month of age for specific conditions like aggressive lymphomas and leukemias, though the typical starting age varies by indication: >1 month for hematologic malignancies, >1 year for nephrotic syndrome, and any age for acute asthma exacerbations. 1

Age-Specific Guidelines by Condition

Hematologic Malignancies

• Prednisolone is approved for use in children >1 month of age for aggressive lymphomas and leukemias, representing the youngest age for which safety and efficacy are established 1

Nephrotic Syndrome

• For children >1 year presenting with idiopathic nephrotic syndrome, corticosteroid therapy should be initiated without requiring kidney biopsy first 2, 3
• Children <1 year with nephrotic syndrome require specialized evaluation before starting prednisolone, as they are more likely to have genetically definable causes rather than idiopathic disease and should be managed differently 2
• Standard dosing for nephrotic syndrome is 60 mg/m²/day or 2 mg/kg/day (maximum 60 mg/day) for 4-6 weeks 4, 3

Asthma and Respiratory Conditions

• Prednisolone can be used at any pediatric age for acute asthma exacerbations at 1-2 mg/kg/day (maximum 60 mg/day) 5, 3
• For children 0-4 years: short-course burst of 1-2 mg/kg/day (maximum 30 mg/day) for 3-10 days 5
• For children 5-11 years: 1-2 mg/kg/day (maximum 60 mg/day) for 3-10 days 5
• Important caveat: Prednisolone should NOT be used for virus-induced wheezing in children <5 years presenting to hospital 3

Duchenne Muscular Dystrophy

• Glucocorticoid initiation is NOT recommended for children <2 years of age who are still gaining motor skills 3
• Typical age for initiating prednisolone is 4-8 years, with standard starting at age 6 years (±2 years) at 0.75 mg/kg/day 3

Infantile Hemangiomas

• Prednisolone at 2-3 mg/kg/day can be used as alternative therapy when propranolol cannot be used, with no specific minimum age restriction mentioned 3

Critical Pre-Treatment Requirements

Immunization Status

• Complete immunization schedule, including varicella vaccination, should be completed before starting steroids in infants and very young children 3
• Live vaccines are contraindicated during immunosuppression with prednisolone ≥20 mg/day for ≥2 weeks 2
• Infants exposed to biologics in utero should not receive live vaccines for 6 months after birth 2

Dosing Considerations for Young Children

Administration Timing

• A single morning dose should be administered to minimize adrenocortical suppression 2, 4
• Recent evidence suggests split dosing (2/3 morning, 1/3 evening) achieves faster remission in nephrotic syndrome relapses (8.02 vs 9.74 days), though this contradicts traditional single-dose recommendations 6

Weight-Based Adjustments

• For significantly overweight children, dosing should be based on ideal body weight to avoid unnecessary steroid exposure 4, 3
• Maximum daily dose typically should not exceed 60 mg, though up to 80 mg may be considered for specific conditions 2, 4

Essential Monitoring Requirements

Growth and Development

• Growth velocity is the most sensitive indicator of systemic corticosteroid exposure and should be monitored closely 3, 1
• Linear growth should be monitored in all children treated with corticosteroids by any route 1
• Children should be titrated to the lowest effective dose to minimize growth effects 3, 1

Other Monitoring Parameters

• Blood pressure at each visit using age and height-specific percentiles 3
• Annual screening for cataracts with long-term use 3
• Annual DEXA scans and vitamin D monitoring for prolonged therapy 3
• Urine glucose screening and blood glucose if positive 3

Common Pitfalls to Avoid

• Do NOT use prednisolone for non-specific cough in children without clear asthma features 3
• Do NOT initiate in children <2 years with Duchenne muscular dystrophy who are still making motor progress 3
• Do NOT delay steroid administration in true asthma exacerbations, as underuse is associated with increased mortality 3
• Courses <10 days do not require tapering, but never stop abruptly after prolonged courses—ensure gradual taper 3
