In simple terms
Chronic spontaneous urticaria persists more than 6 weeks. It is usually not allergic — and is highly treatable.
What you need to remember
- Triage — Most cases are autoimmune or idiopathic.
- Treatment — Second-generation H1 antihistamines first-line, up to 4x standard dose
- Course — Most cases resolve within 1-5 years.
Itchy wheals appearing and disappearing within 24 hours, sometimes with angioedema. Usually not triggered by a specific allergen.
Triage
Most cases are autoimmune or idiopathic. Extensive allergy testing is rarely useful.
Treatment
- Second-generation H1 antihistamines first-line, up to 4x standard dose
- Add omalizumab for refractory disease
- Avoid known triggers: pressure, heat, NSAIDs in some patients
Course
Most cases resolve within 1-5 years. Symptom control rather than cure is the realistic short-term goal.
Daytime sedation from antihistamines is uncommon with modern agents at standard doses.
