Short answer

Oseltamivir is commonly recommended as the preferred flu antiviral during pregnancy when flu is suspected or confirmed, because pregnancy raises the risk of severe flu illness.

Prompt clinician-guided treatment

What is the safest way to think about this?

CDC guidance says pregnant and postpartum people are at higher risk for severe flu complications and recommends prompt antiviral treatment. CDC clinician guidance identifies oral oseltamivir as the preferred treatment during pregnancy.

What is generally okay?

  • Call your clinician promptly for fever, cough, sore throat, body aches, or known flu exposure.
  • Use antiviral medicine only as prescribed, especially if you have asthma, diabetes, heart disease, or high-risk pregnancy.
  • Ask about fever control and hydration along with antiviral treatment.

What should you avoid or double-check?

  • Avoid delaying care while waiting for a flu test if your clinician advises treatment.
  • Avoid borrowing leftover antivirals.
  • Avoid assuming antibiotics treat flu; flu is viral.
