Shingles during pregnancy

By trimester

Weeks 1–13

1st trimester

The reassurance holds from the start. Shingles is a reactivation of a virus your body already knows, which is why it behaves so differently from catching chickenpox for the first time in early pregnancy.

Weeks 14–27

2nd trimester

Nerve pain is often the hardest part, and it can start before the rash shows up. Pain management options in pregnancy are limited enough that this is worth a real conversation rather than toughing it out.

Weeks 28–birth

3rd trimester

The consideration shifts to the newborn. Anyone in the house without chickenpox immunity, including your baby after birth, can catch chickenpox from the rash, so keeping lesions covered matters most now.

What does the evidence show for shingles?

• Shingles comes from the varicella-zoster virus reactivating after a past chickenpox infection, usually showing up as a painful rash on one side of the face or body, sometimes with fever, headache, and nerve pain. 1
• Shingles has not been seen to increase the chance of birth defects, and studies looking at pregnancy outcomes suggest no intrauterine transmission to the fetus. 1
• Maternal herpes zoster does not cause congenital varicella syndrome, which is the syndrome tied specifically to a first chickenpox infection during pregnancy. 2
• The rash is contagious only to people without chickenpox immunity, and someone exposed develops chickenpox rather than shingles; the chance of spreading it is low while the rash stays covered and ends once lesions crust over, usually within 7 to 10 days. 1
• The virus has not been found in breast milk, but a baby should be kept from direct contact with the rash or blisters, and if lesions are on the areola the milk should be pumped and discarded until the rash has scabbed over. 1

When should I call my provider about shingles?

A rash that involves or sits near the eye needs immediate evaluation by an eye specialist, since it can lead to conjunctivitis, inflammation inside the eye, or vision loss if it goes unchecked. A rash that spreads beyond one area of the body, called disseminated zoster, can affect the liver, lungs, or brain and is a more serious pattern that needs urgent same-day evaluation rather than the usual course. Facial weakness or drooping alongside ear pain and a rash can point to Ramsay Hunt syndrome, which also needs prompt specialist evaluation. Consult your healthcare provider the same day for any of these patterns, or if your immune system is weakened. Trust your read on your own body. If something feels off beyond the list above, please consult your healthcare provider rather than waiting it out.
