Which doctor treats this

  • Start with your primary care provider (family doctor or internist).
  • They may send you to a dermatologist (skin doctor).

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.
  • Breastfeeding: Most medicines are fine, but ask. The NIH LactMed database lists what's known about each one.
