What is Oseltamivir?

  • Oseltamivir is an antiviral drug that is used to treat and prevent the flu. It works in a similar way to zanamivir (Relenza). The influenza A and B viruses, which cause the flu, are suppressed and spread less by oseltamivir. It accomplishes this by inhibiting the action of neuraminidase, a virus-produced enzyme that allows viruses to spread from infected to healthy cells. The symptoms and duration of influenza infection are decreased by preventing the virus from spreading from cell to cell. If treatment is begun within 48 hours of the onset of symptoms, oseltamivir reduces the duration of symptoms by one and a half days on average.
