Active ingredients: zanamivir
What it is used for
Treatment: Relenza (zanamivir) is indicated for the treatment of infections due to Influenza A and B viruses in adults and children aged 5 years and older. Treatment should commence as soon as possible but no later than forty-eight hours after the onset of the initial symptoms of infection (see Precautions). Prophylaxis: Vaccination remains the primary method of preventing and controlling influenza. Relenza is indicated for prophylaxis of Influenza A and B in adults and children (5 years and older) to reduce transmission among individuals in households with an infected person. Relenza is indicated for prophylaxis of influenza A and B during community outbreaks only in circumstances where such prophylaxis is justified (such as when vaccine that antigenically matches circulating influenza is not available or there is a pandemic). It is not recommended for routine prophylaxis against influenza infection.
