This MomJunction post tells you about the causes of hives during pregnancy, their treatments, and possible complications.
Is It Normal To Have An Outbreak Of Hives During Pregnancy?
There is no research to suggest that there is an increased risk of having hives during pregnancy. Your possibility of developing hives during pregnancy is the same as the risk during non-pregnancy times.
What Causes Hives During Pregnancy?
As your body undergoes changes during pregnancy, the immune system may perceive these changes as foreign. Thus, it releases histamine into the bloodstream, and this histamine could cause hives on your body and face (1).
Hives may be triggered by factors including (2):
- Animal dander
- Insect bites
- Fish, shellfish, eggs, nuts, milk, or other foods
- Exposure to sun, cold, or water
- Emotional stress
A severe kind of hives called pruritic urticarial papules and plaques of pregnancy (PUPPP) could develop in the third trimester. It appears in the stretch marks of the belly and spreads towards the chest and legs (3).
Symptoms Of Hives During Pregnancy
Hives mostly appear as tiny grouped welts on the arms, legs, and back. They may keep changing places too.
Pregnancy hives may be associated with any of the following signs and symptoms.
- Raised red welts on the skin
- Severe pain
- Localized swelling (angioedema)
- Itching sensation

Treatment For Hives During Pregnancy
Do not self-medicate by taking over-the-counter medications. Consult your doctor and follow their prescription. For pregnancy hives, your doctor may prescribe over-the-counter antihistamines such as Benadryl, Allegra, Claritin, Chlor-Trimeton, and Zyrtec (4).
For a severe rash, such as PUPPP, they may suggest oral medications and anti-itch creams.
Natural Remedies For Hives During Pregnancy
Some natural remedies have been found to provide relief from itching and rashes. Some of them are:
- An oatmeal bath is found to relieve itching that is caused by hives (5). It is anti-inflammatory and has skin-protecting properties.
- Aloe vera is known for its cooling effect. Extract fresh aloe vera gel and apply it to the affected area (6). Leave it for some time and wash with cold water.
- Take a bath in lukewarm water as hot water may trigger excessive blood flow, aggravating the itch. Coldwater is a better choice as it could reduce the itch.

- It is believed that a clean cloth dipped in milk dabbed on the affected area may ease inflammation.
