What is Relenza used for?
Relenza is used to treat illness due to flu virus in people 7 years and older who show flu symptoms for no more than 2 days. Relenza is also used to reduce the chance of getting influenza illness, in people 5 years and older.

Special Warnings with Relenza:

• Some patients have had wheezing or serious breathing problems when they used Relenza. Many but not all of these patients had previous asthma or chronic obstructive pulmonary disease.
