How effective is Omalizumab for urticaria in adults?

Question

Hello doctor,

I am 38 and have had hives on and off for over six months. They appear mostly at night or after stress and last for hours, leaving red welts and swelling. My IgE was 224, and ANA was borderline positive. I have been on antihistamines but need multiple doses daily for relief.

So, I would like to ask you the following questions -

Could this be autoimmune urticaria or something more serious? Are blood tests enough to confirm it?
My doctor mentioned Omalizumab if symptoms persist. How effective is it for chronic cases?
Should I see an allergist or rheumatologist?
Also, what daily precautions can reduce flare frequency or severity naturally?

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Based on your history of hives persisting for more than six months, this is likely chronic spontaneous urticaria (CSU). The fact that symptoms worsen with stress and at night is not uncommon.

Your elevated IgE (immunoglobulin E) and borderline ANA (antinuclear antibody) may point toward an autoimmune component, especially if antihistamines are not fully controlling symptoms. While there is no single definitive test to confirm autoimmune urticaria, we sometimes check for anti-thyroid antibodies and consider an autologous serum skin test if autoimmune involvement is suspected.

For now, it is important to stay on a daily non-sedating antihistamine, and in some cases, we increase the dose up to four times the standard under guidance. If that is still ineffective, Omalizumab (Xolair), a monoclonal antibody, is a great next-line option and has shown excellent results in many patients with chronic urticaria. It is usually well-tolerated and can bring significant relief within a few weeks.

If systemic symptoms (fever, joint pains, angioedema, or other autoimmune signs) ever show up, a referral to a rheumatologist would be helpful. Otherwise, an allergist or immunologist can manage most CSU cases.

In terms of lifestyle, reducing stress, avoiding known triggers (tight clothing, certain foods, NSAIDs (non-steroidal anti-inflammatory drugs)), and using gentle, fragrance-free skin products can help reduce flare frequency.

I hope I have answered your question. Let me know if I can assist you further.
