Why is this medication prescribed?

Zanamivir is primarily available as an inhaled medication and is not administered orally. Zanamivir is an antiviral medication used to treat influenza (the flu) caused by influenza A and B viruses. It is a neuraminidase inhibitor, which means it works by blocking the activity of the neuraminidase enzyme on the surface of the influenza virus.

How should this medicine be used?

• Administration: Zanamivir is administered through oral inhalation using a device called a Diskhaler.
• Timing of Use: It is important to start zanamivir treatment as soon as possible after the onset of influenza symptoms, typically within 48 hours.
