Can chronic urticaria affect my pregnancy at 28?

Question

Hello doctor,

I am a 28-year-old woman who has been experiencing chronic urticaria (hives) for the past six months. Despite trying multiple antihistamines, the itchy welts continue to appear almost daily, primarily on my arms, legs, and torso. My allergist has not been able to identify a specific trigger, and we have ruled out the most common food and environmental allergens.

What is particularly concerning is that I recently found out I am pregnant, about eight weeks along. I am very worried about continuing the antihistamines I have been taking (Cetirizine and Famotidine) because I am unsure if they are safe for my baby. The itching is so severe that it disrupts my sleep, and the stress of dealing with both the hives and the pregnancy is becoming overwhelming.

I have also noticed that the hives tend to flare up more intensely around my menstrual cycle. Now that I am pregnant, I am wondering if hormonal changes during pregnancy might make them better or worse.

Additionally, I have been experiencing more severe morning sickness than what my friends described during their pregnancies, and I am not sure if this could be related to my immune system being overactive. My dermatologist mentioned that pregnancy can sometimes trigger or worsen autoimmune conditions, which has increased my anxiety.

Are the antihistamines I have been taking safe to continue during pregnancy, or do I need to switch to different medications?
Could my chronic urticaria be related to hormonal changes, and will pregnancy make it better or worse?
Is there a connection between my severe morning sickness and urticaria? Could they both be immune-related?
What pregnancy-safe treatments are available for managing chronic hives and severe itching?
Could my urticaria be a sign of an underlying autoimmune condition that might affect my pregnancy?
Are there any risks to my baby from having chronic urticaria during pregnancy?
Should I see a high-risk obstetrician because of my chronic urticaria diagnosis?
Will I be able to breastfeed safely while taking antihistamines after delivery?

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I have gone through your query and understand your concern.

Antihistamine safety: Do not stop or change your current medication without consulting your doctor. Cetirizine is generally considered a safer option during pregnancy, but your doctor should confirm this and adjust the dose if necessary. Famotidine may also be used, but only under strict medical supervision.

Hormones and urticaria: Yes, hormonal changes can definitely influence chronic urticaria. Pregnancy can make the condition better, worse, or cause no change at all, it is unpredictable from person to person.

Morning sickness link: Severe morning sickness (hyperemesis gravidarum) and chronic urticaria can both have immune and hormonal components, but one does not necessarily cause the other. It is essential to report your severe nausea to your obstetrician or gynecologist.

Pregnancy-safe treatments: Second-generation antihistamines such as Loratadine or Cetirizine are typically first-line options during pregnancy. For severe or uncontrolled cases, your doctor may also consider pregnancy-safe medications like Omalizumab (Xolair).

Autoimmune condition: Chronic spontaneous urticaria is often autoimmune-related. While it should not directly harm the baby, it requires active management. It does not automatically mean you have another systemic autoimmune disease.

Risks to the baby: The condition itself poses little direct risk to the baby. The main concerns are uncontrolled symptoms leading to severe maternal stress, sleep deprivation, or the use of unsafe medications.

High-risk obstetrician: It is an excellent idea to consult with a maternal-fetal medicine (MFM) specialist, in addition to your obstetrician or gynecologist, to co-manage your care alongside your allergist and dermatologist.

Breastfeeding: Many antihistamines are considered compatible with breastfeeding, but you should discuss specific medications with your pediatrician and allergist before use.

Action plan:

Contact your obstetrician, gynecologist, and allergist today to discuss the safety of your medications during pregnancy.
Do not stop your current medications abruptly.
Request a referral to a maternal-fetal medicine (high-risk obstetrician) specialist.
