Relenza. Is it for you?

Relenza is an oral inhalent medicine to treat flu (infection caused by influenza virus) in adults and children aged 7 years and older, where the symptoms started within the last two days.

Similar to Tamiflu, it belongs to a group of medicines called neuraminidase inhibitors, this means that the virus is unable to reproduce itself. These medications attack the influenza virus and prevent it from spreading inside your body. Relenza actually treats the flu at its source by attacking the virus that causes the flu, rather than masking symptoms until the virus subsides. Although it is impossible to know if you have flu without having lab tests, the general symptoms of flu include sudden onset of fever and chills, cough, muscle pain, headache, fatigue and weakness. You may also get a stuffy nose and sore throat.

How does Relenza work?

Relenza prevents the virus from reproducing itself and thus stops it spreading inside the body. You may already have the flu, but this medicine attacks the flu virus in your body.

Relenza Dosage

Relenza is a powder that is inhaled two times a day for a five day treatment period. It is inhaled through a Diskhaler. Should you be unsure of how to use a diskhaler, any healthcare professional or pharmacy should be able to show you.
