Zanamivir, marketed under the brand name Relenza, is an FDA- and EMA-approved antiviral drug used for the treatment and prevention of Influenza A and B.

It is administered via oral inhalation using a Diskhaler, with each dose delivering 10 mg (two 5 mg blisters). Zanamivir is approved for use in adults and children (≥7 years for treatment, ≥5 for prevention). Relenza offers a localized delivery option with minimal systemic side effects.
