Pruritic urticarial papules and plaques of pregnancy

Updated: 2023-04-11

Description

An itchy rash that can happen during the last three months of pregnancy, usually in the last several weeks and sometimes right after a baby is born.

Overview

Pruritic urticarial papules and plaques of pregnancy (PUPPP) also is called polymorphic eruption of pregnancy. The cause of this itchy rash isn't clear. It's more common in people whose skin stretches a great deal during pregnancy, especially those who are pregnant with more than one baby.

Symptoms

PUPPP appears as red bumps. They usually start on stretch marks across the belly. The rash often spreads to the legs and buttocks. In some cases, it may appear on the arms and back too. The rash usually is widespread and very itchy.

Treatments

The goal of treatment is to ease itching. A cream with corticosteroid medicine usually is the first treatment option. Sometimes, an antihistamine medicine may be used too. In severe cases, a pill that has corticosteroids, such as prednisone, may be recommended. The rash usually goes away about two weeks after the baby is born.
