What’s New in Rashes in Pregnancy (PUPPP, acne, rosacea)

Pregnancy is a time of joy, hope, and bliss. Well, maybe not all the time…and definitely not when a rash develops. Historically, many physician and patients have decided to forego medication that could help the numerous itchy rashes that can develop (including PUPPP, pruritic urticarial papules and plaques of pregnancy, pictured above). Recently, a study was completed comparing thousands of pregnant women who decided to utilize corticosteroid medication to those who did not. There was no association found between topical corticosteroid usage and the birth outcomes analyzed (orofacial cleft, low birth weight, preterm delivery, fetal death, low Apgar score, or mode of delivery) as long as the amount of potent/superpotent topical corticosteroid usage was less than 300 grams (~5 large tubes) during the entire pregnancy.

Thus, I wanted to let our pregnant patients know that they do not have to suffer for the sake of their baby. This also applies to acne and rosacea as there are multiple medications that have not demonstrated a risk to the fetus in studies performed either in pregnant women or laboratory animals.

If you or your significant other is pregnant and has itching, acne, or rosacea, I look forward to seeing you. Please make an appointment for a consultation at (626) 331-6411.
