Chronic Spontaneous Urticaria (Hives)
Description
A condition in which hives (itchy, red welts) appear for six weeks or more with no known cause. The hives can appear anywhere on the body and can change in size and shape. It is often a frustrating and uncomfortable condition.
Common Symptoms
- Batches of red or skin-colored welts (wheals) that can appear anywhere on the body
- Intense itching (pruritus)
- Painful swelling (angioedema) around the eyes, cheeks or lips
Common Causes
- The cause is unknown in most cases (spontaneous), but it is thought to be an autoimmune reaction. It is not caused by an allergy to an external substance.
Treatment Information
Long-acting, non-drowsy antihistamines are the first-line treatment. For those who do not respond, treatments like omalizumab (a biologic drug) or cyclosporine may be used.
