Recommended Dose of Wysolone (Prednisolone) for Urticaria
For acute severe urticaria in adults, prednisolone 50 mg daily for 3 days is the guideline-recommended regimen, though lower doses are frequently effective and should be considered to minimize corticosteroid exposure. 1, 2
Treatment Algorithm for Urticaria
First-Line Therapy (Always Start Here)
- Begin with second-generation H1 antihistamines (cetirizine, loratadine, desloratadine, fexofenadine, levocetirizine) at standard doses for 2-4 weeks 1
- More than 40% of patients respond to antihistamines alone 1
Second-Line: Dose Escalation
- If inadequate response after 2-4 weeks, increase antihistamine dose up to 4 times the standard dose before considering corticosteroids 1, 3
- Approximately 75% of patients respond to antihistamine dose escalation 1
Third-Line: Short-Course Corticosteroids (Only for Severe Acute Cases)
Adult Dosing:
- Prednisolone 50 mg daily for 3 days for severe acute urticaria or angioedema affecting the mouth 4, 1, 2
- Lower doses (25 mg daily for 3 days) are frequently effective and should be considered first to minimize exposure 1, 2, 5
- Maximum duration: 3-10 days for severe acute exacerbations 1, 2, 3
Pediatric Dosing:
- Prednisolone 1-2 mg/kg/day in divided doses for short courses (3-10 days maximum) 6
- For children with asthma-related urticaria: 1-2 mg/kg/day until symptoms resolve, typically 3-10 days 6
Critical Contraindications and Warnings
Absolute Contraindication
- Long-term oral corticosteroids should NOT be used in chronic spontaneous urticaria (Strength of recommendation A) 4, 1, 2
- This is a firm contraindication due to cumulative toxicity and unfavorable risk-benefit ratio 1, 2
- Chronic corticosteroid use is associated with dose- and time-dependent toxicity 3
When Corticosteroids Should Be Avoided
- Never use corticosteroids as first-line treatment when antihistamines are sufficient 1
- Never continue corticosteroids beyond 3-10 days 1, 2
- A recent 2021 randomized controlled trial found that adding IV dexamethasone to antihistamines did not improve pruritus scores at 60 minutes, and oral corticosteroids for 5 days were associated with more persistent urticaria activity at 1-week and 1-month follow-up 7
Common Pitfalls to Avoid
Using corticosteroids too early: Always optimize antihistamine therapy first (standard dose, then up to 4x dose) before adding corticosteroids 1, 3
Prolonged corticosteroid courses: The evidence for benefit beyond 3-10 days is questionable, while cumulative toxicity is well-established 1, 3
Chronic corticosteroids for chronic urticaria: This is the most critical error—instead, escalate to omalizumab (300 mg subcutaneously every 4 weeks) or cyclosporine (4 mg/kg daily) for antihistamine-refractory chronic urticaria 1, 2, 3
Ignoring lower effective doses: Starting with 25 mg prednisolone daily instead of 50 mg can be equally effective while minimizing exposure 5
Refractory Cases (After Failed Antihistamine Escalation)
For chronic urticaria unresponsive to high-dose antihistamines:
- Omalizumab 300 mg subcutaneously every 4 weeks is effective in 70% of antihistamine-refractory patients 3, 8
- Cyclosporine 4 mg/kg daily for up to 2 months is effective in approximately two-thirds of severe autoimmune urticaria cases 4, 2, 3
- H2 antihistamines and leukotriene antagonists add minimal benefit and are no longer strongly recommended 3, 8
Special Considerations
Emergency Situations
- For anaphylaxis or severe laryngeal angioedema: Epinephrine 0.5 mL of 1:1000 (500 µg) intramuscularly immediately 1
- Corticosteroids are adjunctive only and do not replace epinephrine in true emergencies 1
