Which doctor treats this

Children, pregnancy, and older adults
- Pregnancy: Tell your doctor about rash exposures.
Pregnancy and breastfeeding
- If you're pregnant or planning to be, tell your prenatal provider about this condition.
- Some skin medicines, like isotretinoin and retinoid creams, aren't safe in pregnancy.
- Some infections can pass to the baby during pregnancy or birth. Tell your provider if you've been exposed.
- Don't start or stop any medicine on your own. Some are safe in pregnancy and some need to be changed.
- Ask before taking any pain reliever. The FDA advises avoiding ibuprofen and naproxen after 20 weeks unless your doctor says to.
