Children, pregnancy, and older adults

  • Adults 30 to 60: Most common.

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.
