Episode 905: Oseltamivir (Tamiflu) for Influenza

Contributor: Aaron Lessem MD

Educational Pearls:

  • Oseltamivir (Tamiflu) is an antiviral medication used commonly to treat influenza

  • Trials show that the medication reduces the duration of illness by less than 1 day (~16 hours in one systematic review)

    • Benefit only occurs if taken within 48 hours of symptom onset

    • Must be taken for 5 days

  • A 2024 meta-analysis reviewed 15 randomized-controlled trials for the risk of hospitalization

    • No reduction in hospitalizations with oseltamivir in patients over the age of 12

    • No difference in high-risk patients over the age of 65 or those with comorbidities

      • The authors note that the confidence interval in these populations is wide, indicating a need for subsequent studies in high-risk populations

  • Oseltamivir is associated with adverse effects including nausea, vomiting, and neurologic symptoms

    • The risk of adverse effects may outweigh the benefits of a small reduction in the duration of illness
