Why have I been experiencing hives daily despite treatment?

Question

Hello doctor,

I have been experiencing hives almost every day for four months, and no one has been able to explain why. Allergy tests came back negative for everything, and blood work is reportedly normal. My dermatologist said it is chronic spontaneous urticaria, which feels like a way of saying the cause is unknown. Is this condition really as common as it is being described?

I am currently taking antihistamines (Cetirizine 10 mg), but they do not provide adequate relief on some days. The itching becomes severe at night, leading to scratching and disturbed sleep. Would it be appropriate to ask for a higher dose or a different antihistamine? It feels like there may be better treatment options available.

I would also like to know more about Omalizumab. My dermatologist mentioned it as a possible next step if antihistamines do not work, but it sounds intense and expensive, which causes concern. Does it work effectively for chronic hives, or does it vary significantly between individuals? The aim is to restore normal skin condition.

Kindly advise.

Hello,

Welcome to icliniq.com.

I have read the query and understand the concern.

The diagnosis of chronic spontaneous urticaria is a well-recognized clinical condition, and it is relatively common. In the majority of cases, no specific external trigger is identified despite appropriate testing. This does not indicate a missed diagnosis, but rather reflects a condition related to mast cell instability and immune system dysregulation.

The presence of daily hives for four months, along with severe itching and sleep disturbance, suggests inadequate symptom control rather than treatment failure.

Regarding antihistamine therapy, Cetirizine 10 mg once daily is considered a starting dose. According to standard dermatological practice, the dose can be increased up to two to four times the standard dose under medical supervision.

Alternatively, a switch to other second-generation antihistamines such as Fexofenadine or Levocetirizine may be considered. In some cases, combination therapy is required. Therefore, it is appropriate to discuss dose escalation or a change in medication with the treating doctor.

Regarding Omalizumab, it is a well-established and targeted treatment for chronic spontaneous urticaria. It works by blocking immunoglobulin E (IgE)-mediated activation of mast cells. It is administered as a monthly injection and has shown high response rates, with many patients experiencing significant or complete relief.

It is generally well tolerated and is typically recommended when high-dose antihistamines fail to adequately control symptoms. Overall, the condition is genuine and relatively common, but the current level of symptom control appears suboptimal.

There are effective step-up treatment options available, both within antihistamine therapy and beyond. If symptoms are significantly affecting sleep and quality of life, a follow-up consultation for treatment adjustment is strongly recommended rather than continuing with inadequate relief.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.
