Relenza (zanamivir)

Relenza (zanamivir) is an antiviral medication used to treat and prevent influenza (flu) infections. It works by blocking a protein on the flu virus, preventing the virus from spreading within your respiratory system. This helps reduce the severity and duration of symptoms if taken early in the infection. Relenza is inhaled through the mouth using a special device, making it easier to deliver directly to the respiratory tract. It’s most effective when started soon after flu symptoms appear or as directed for prevention during outbreaks.
