What if hives persist with swelling despite treatment?

Question

Hello doctor,

I am 26 and have been experiencing daily hives that appear and disappear without any apparent trigger. My IgE levels were elevated last month. I have tried higher doses of antihistamines like Cetirizine and Fexofenadine, but I still experience frequent flare-ups. Occasionally, I also get lip swelling and mild chest tightness.

Could this be chronic spontaneous urticaria? If antihistamines are not effective, would Omalizumab be the next step in treatment? Should I consider further allergy testing, or could this be autoimmune-related?

Kindly suggest.

Hello,

Welcome to icliniq.com.

I understand your concern. It sounds like you are dealing with chronic spontaneous urticaria, especially given the daily hives without a clear trigger and elevated immunoglobulin E (IgE) levels. While high IgE can suggest an allergic or immune-related process, it is not always definitive. Since you have already tried higher doses of antihistamines such as Cetirizine and Fexofenadine without much relief, your condition may be resistant to standard antihistamine therapy.

In such cases, Omalizumab (brand name Xolair) is often considered the next step in treatment. It is an injectable medication approved for use in chronic spontaneous urticaria that does not respond to antihistamines. Omalizumab targets and neutralizes immunoglobulin E, which plays a key role in allergic reactions. After starting this treatment, many patients experience significant improvement in both hives and swelling.

Regarding further evaluation, if common allergens have already been ruled out, additional allergy testing may not be necessary. However, because chronic spontaneous urticaria can sometimes be related to autoimmune disorders, it would be worthwhile to discuss further testing for autoimmune markers with your doctor. Consult your healthcare provider to explore Omalizumab as a treatment option, and feel free to share updates on your progress.

I hope this information helps you.

Thank you.
