Chronic spontaneous urticaria (CSU) — also known as chronic hives — refers to raised, itchy welts or patches on the skin that appear without a clear trigger and last longer than 6 weeks. When hives persist beyond 24 hours, they are more likely linked to lupus itself rather than an outside cause like an allergy.

Chronic spontaneous urticaria (CSU) — also known as chronic hives — refers to raised, itchy welts or patches on the skin that appear without a clear trigger and last longer than 6 weeks. When hives persist beyond 24 hours, they are more likely linked to lupus itself rather than an outside cause like an allergy.
About 10% of people with lupus develop hives. One theory is that lupus can cause the immune system to react against the body's own cells — a kind of internal allergic reaction. As for treatment, the best approach really depends on the individual, so working closely with a rheumatologist and/or dermatologist is key. General management options may include:
- Antihistamines to reduce the histamine response causing the hives
- Immunosuppressive medications already used for lupus management
- Avoiding known triggers like sun exposure and UV light
- Topical creams or ointments recommended by a dermatologist
- Compression — a MyLupusTeam member noted that compression sleeves helped stop itching
Always flag new or worsening skin symptoms to your doctor promptly, as some related conditions can lead to complications if left untreated.
