CLINICAL RATIONALE
Guidelines |
Influenza Antiviral treatment is recommended by the Centers for Disease Control and Prevention (CDC) as early as possible for any patient with confirmed or suspected influenza who: is hospitalized, has severe, complicated, or progressive illness, or is at higher risk for influenza complications. Antiviral treatment also can be considered for any previously healthy, symptomatic outpatient not at high risk for influenza complications, who is diagnosed with confirmed or suspected influenza, on the basis of clinical judgement, if treatment can be initiated within 48 hours of illness onset. Recommended duration for antiviral treatment is 5 days for oral oseltamivir or inhaled zanamivir. For the treatment of uncomplicated influenza with intravenous peramivir or oral baloxavir, a single dose is recommended. Longer daily dosing (oral oseltamivir or intravenous peramivir) can be considered for patients who remain severely ill after 5 days of treatment.(5) The CDC does not recommend widespread or routine use of antiviral medications for chemoprophylaxis except as one of multiple interventions to control institutional influenza outbreaks. Routine use of post-exposure chemoprophylaxis is not recommended; one reason for this is to avoid sub-therapeutic treatment dosing if infection is already established, although the possibility of whether antiviral resistant viruses could emerge is unknown. Antiviral medications can be considered for chemoprophylaxis to prevent influenza in certain situations, such as: prevention in people at high risk to influenza complications during the first two weeks following vaccination after exposure to a person with influenza, prevention for people at high risk for complications from influenza who cannot receive influenza vaccine due to a contraindication after exposure to a person with influenza, and prevention for people with severe immune deficiencies or others who might not respond to influenza vaccination, such as people receiving immunosuppressive medications, after exposure to a person with influenza. To be effective as chemoprophylaxis, an antiviral medication must be taken each day for the duration of potential exposure to a person with influenza and continued for 7 days after the last known exposure. For persons taking antiviral chemoprophylaxis after inactivated influenza vaccination, the recommended duration is until immunity after vaccination develops (antibody development after vaccination takes about two weeks in adults and can take longer in children depending on age and vaccination history). For control of outbreaks in institutional settings (e.g., long-term care facilities for elderly people and children) and hospitals, CDC recommends antiviral chemoprophylaxis with oral oseltamivir or inhaled zanamivir for a minimum of 2 weeks and continuing up to 1 week after the last known case was identified. Antiviral chemoprophylaxis is recommended for all residents, including those who have received influenza vaccination. Baloxavir is approved for post-exposure prophylaxis (single-dose) of influenza in persons aged 5 years and older.(3) COVID-19 (SARS-CoV-2) and Influenza During periods of community co-circulation of influenza viruses and SARS-CoV-2, empiric antiviral treatment of influenza is recommended as soon as possible for the following priority groups: hospitalized patients with respiratory illness, outpatients with severe, complicated, or progressive respiratory illness, and outpatients at higher risk for influenza complications who present with any acute respiratory illness symptoms (with or without fever). Patients who require hospitalization and are suspected of having either or both viral infections should receive influenza antiviral treatment with oseltamivir as soon as possible without waiting for influenza testing results. Treatment for influenza is the same for all patients regardless of SARS-CoV-2 coinfection. Clinicians can consider starting early (less than or equal to 48 hours after illness onset) empiric antiviral treatment of non-high-risk outpatients with suspected influenza based upon clinical judgement. SARS-CoV-2 and other etiologies of influenza-like illness should also be considered.(5) |
Safety |
Zanamivir is contraindicated in patients with history of allergic reaction to any ingredient of Relenza, including milk proteins.(1) |
