Which doctor treats this

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

Back to school, work, or sports

  • Stay home until you've taken antibiotics for 5 days.

Children, pregnancy, and older adults

  • Pregnancy: Tdap shot in each pregnancy protects the baby.

Pregnancy and breastfeeding

  • If you're pregnant or planning to be, tell your prenatal provider about this condition.
  • 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.
