The Centers for Disease Control and Prevention (CDC) has issued a notice regarding increased influenza A(H3N2) activity and its clinical implications, a summary of influenza antiviral drug treatment recommendations, an update about approved treatment drugs and supply for the 2017-2018 season, and background information for patients about influenza treatment. Recommendations include:
- CDC recommends antiviral medications for the treatment of influenza as an important adjunct to annual influenza vaccination.
- All hospitalized, severely ill, and high-risk patients with suspected confirmed influenza should be treated with antivirals.
- Antiviral treatment should be started as soon as possible after illness onset and should not be delayed even for a few hours to wait for the results of testing.
- The most accurate influenza tests are molecular assays.
- Neuraminidase inhibitors can benefit other individuals with influenza. 3 prescription neuraminidase inhibitor antiviral medications are recommended for use the US during the 2017-2018 season: iseltamivir (Tamiflu), zanamivir (Relenza), and peramivir (Rapivab).
- Additional considerations for clinicians include bacterial infections and adverse events with antiviral use.
