Are daily antihistamines safe for women with urticaria?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am a 34-year-old woman and keep getting itchy red patches on my arms and legs. They appear and disappear randomly, sometimes worsening before my period. I have not changed my soap or diet. Could this be chronic urticaria?

I would like to know:

  • Are daily antihistamines safe for women trying to conceive?

  • Do I need allergy testing?

  • What triggers should I watch for to prevent flare-ups?

Please help.

Thank you in advance.

Hi,

Welcome to icliniq.com.

I read your query and can understand your concern.

Considering your history and symptoms, it seems like you may have chronic urticaria. This is a condition where itchy, red, raised patches appear on the skin repeatedly over time. Since you are planning a pregnancy, many medications are restricted, so it is important to consult a dermatologist before starting any treatment.

Here are some suggestions for you:

1. Identify triggers: Common triggers include harsh soaps, rough clothing, certain foods, or environmental factors. Avoiding these can help prevent flare-ups.

2. Medication options: Some antihistamines, like Levocetirizine, are generally considered safe during pregnancy, but should only be started after your doctor’s advice. Other antihistamines, such as Fexofenadine, can also be considered under supervision.

3. Investigations: Your doctor may recommend tests like:

  • CBC (complete blood count) checks overall blood health.

  • ESR (erythrocyte sedimentation rate) and CRP (C-reactive protein) are the markers of inflammation.

  • Thyroid function tests to rule out thyroid issues.

  • The ANA (antinuclear antibody) test checks for autoimmune causes.

4. Advanced treatment: If symptoms persist for more than three months despite medications, Omalizumab (an anti-IgE (immunoglobulin E injection that reduces allergic reactions) may be considered by your doctor.

5. Lifestyle measures: Stress management, good skin hygiene, and regular physical activity can help reduce flare-ups.

You should see a dermatologist in person whenever you have an acute rash, so it can be properly examined. You can discuss the above treatment options with your doctor to choose the safest plan for you.

I hope this helps.

Kindly revert so I can assist you further.

Thank you.
