Prelone (Prednisolone) Dosing
Prednisolone dosing is highly condition-specific, ranging from 5-60 mg/day, with the FDA-approved range being 5-60 mg/day (1.67-20 mL of oral solution) depending on disease severity, and most conditions requiring initial doses of 0.5-1 mg/kg/day. 1
General Dosing Principles
Adult Dosing by Indication
Autoimmune Hepatitis:
- Initial dose: 30 mg/day, tapering to 10 mg/day over 4 weeks 2
- Higher initial doses up to 1 mg/kg/day may be used for more rapid normalization of transaminases 2
- Maintenance: 5-10 mg/day combined with azathioprine for at least 2 years 2
- For patients intolerant of azathioprine: 60 mg/day, reducing over 4 weeks to 20 mg/day 2
Tuberculous Pericarditis:
- 60 mg/day for 4 weeks 2, 3
- Then 30 mg/day for 4 weeks 2, 3
- Then 15 mg/day for 2 weeks 2, 3
- Then 5 mg/day for week 11 (final week) 2, 3
- This regimen significantly reduces mortality (3% vs 14%) 3
Multiple Sclerosis Acute Exacerbations:
General Inflammatory Conditions:
- Initial dose range: 5-60 mg/day depending on severity 1
- Weight-based dosing: 0.5-1 mg/kg/day for most conditions 3
- Maximum usual dose: 60 mg/day 3, 1
Pediatric Dosing
General Range:
Nephrotic Syndrome:
- 60 mg/m²/day in 3 divided doses for 4 weeks 1
- Followed by 40 mg/m²/day as single dose alternate-day therapy for 4 weeks 1
Asthma (Uncontrolled):
- 1-2 mg/kg/day in single or divided doses 1
- Continue "burst" therapy for 3-10 days until peak expiratory flow reaches 80% of personal best 1
- No evidence that tapering prevents relapse 1
Infantile Spasms:
- 8 mg/kg/day (maximum 60 mg/day) divided in 3 daily doses for 14 days 4
- Response rate of 59% in treatment-naive patients 4
Tapering Strategy
Standard Taper:
- Reduce by one-third to one-quarter until reaching 15 mg/day 3
- Then reduce by 2.5 mg steps until 10 mg/day 3
- Then reduce by 1 mg/month until minimum effective dose 3
- For autoimmune hepatitis: reduce by 2.5 mg/day each month with monitoring 2
Important Caveat: After long-term therapy, withdraw gradually rather than abruptly 1
Administration Timing
Standard Approach:
- Single morning dose for most conditions 3
- Divided doses may be necessary for severe diseases requiring continuous control 3
Alternative Regimen:
- Twice daily fractionated dosing (e.g., 2 x 1.25 mg/day) may allow lower total daily dose and appears less diabetogenic than once-daily dosing 5
Dose Equivalencies
5 mL of prednisolone oral solution (15 mg prednisolone base) equals: 1
- Prednisone: 15 mg
- Methylprednisolone: 12 mg
- Dexamethasone: 2.25 mg
- Hydrocortisone: 60 mg
- Cortisone: 75 mg
Critical Monitoring Requirements
Mandatory for All Long-Term Therapy:
- Calcium and vitamin D supplementation 2, 3
- DEXA scans every 1-2 years 2, 3
- Active treatment of osteopenia/osteoporosis 2
Signs of Overdose: 3
- Weight gain, insomnia, peripheral edema
Signs of Underdose: 3
- Lethargy, nausea, loss of appetite, weight loss, increased pigmentation
Important Clinical Pitfalls
Dose Ceiling Effect:
- Doses above 0.75 mg/kg/day (52.5 mg for 70 kg patient) provide no additional benefit 3
- Doses above 30 mg/day associated with significant mortality, particularly in elderly patients 3
Non-Response Management:
- If no response within 5-7 days, increase dose by 50-100% increments 3
- Consider IV pulsed corticosteroids if dose exceeds 1 mg/kg/day 3
Frail Elderly Patients:
- Use caution with standard dosing; consider lower initial doses 2
