Prednisolone Dosing for Ulcerative Colitis Flares
For moderate to severe ulcerative colitis flares, prescribe prednisolone 40 mg orally once daily as a single morning dose, then taper gradually over 6-8 weeks. 1, 2
Standard Dosing Regimen
- Initial dose: 40 mg daily as a single morning dose for moderate to severe UC flares 1, 3
- Single daily dosing is preferred over split-dosing because it is equally effective and causes less adrenal suppression 1, 3
- Duration: Taper over 6-8 weeks after achieving clinical response 1, 2
Evidence Base for 40 mg Dose
- The 40 mg dose is based on Baron's studies demonstrating superiority over 20 mg/day 1
- No additional benefit exists with doses above 40-60 mg/day, and higher doses increase adverse effects 1
- This represents a strong recommendation with high-quality evidence from the British Society of Gastroenterology 1
Treatment Response Timeline
- Assess response within 2 weeks of initiating prednisolone 40 mg/day 1, 3
- Clinical and endoscopic improvements may be seen within 2 weeks 1
- If no response after 2 weeks, consider treatment escalation to biologics or hospital admission depending on systemic symptoms 1, 3
Alternative Corticosteroid Options
For patients wishing to avoid systemic corticosteroids:
- Budesonide MMX 9 mg/day for 8 weeks (topically-acting oral corticosteroid) 2, 3
- Beclomethasone dipropionate 5 mg/day for 4 weeks (shown to be non-inferior to prednisolone in mild-moderate UC) 2, 3
Critical Safety Considerations
Expected Adverse Effects
- Approximately 50% of patients experience short-term adverse events including acne, edema, sleep disturbance, mood changes, glucose intolerance, and dyspepsia 1, 2, 3
When to Escalate Therapy
Patients requiring treatment escalation (not maintenance corticosteroids):
- Two or more courses of corticosteroids in the past year 1, 2, 3
- Corticosteroid-dependent disease (unable to taper off) 1, 2, 3
- Corticosteroid-refractory disease (no response after 2 weeks) 1, 3
Escalation options include: thiopurines, anti-TNF therapy, vedolizumab, or tofacitinib 1, 2, 3
Common Pitfall to Avoid
Do not prolong high-dose oral corticosteroids beyond 2 weeks without response, as this has diminishing chance of achieving remission and increases risk of infective, metabolic, and surgical complications 1
Severe Disease Requiring Hospitalization
For patients with systemic symptoms (fever, severe pain, significant anemia, generally unwell):
