Concludes “Chemoprophylaxis with antiviral drugs is not recommended for healthy persons exposed to influenza. A neuraminidase inhibitor, either oseltamivir (Tamiflu) or zanamivir (Relenza), remains the drug of choice for treatment of patients with influenza. Oseltamivir is preferred for use in pregnant women and in patients with underlying airway disease.” Evidence from the the Cochrane review is not cited.
