Zanamivir, sold under the brand name Relenza among others, is a medication used to treat and prevent influenza due to influenza A or B viruses. It is used by breathing in the powder or by injection into a vein.

Common side effects include headache, dizziness, bronchitis, and cough. Use is not recommended in those with asthma or COPD. While it does not appear to cause harm in pregnancy or breastfeeding, it has not been well studied in this population. It is a neuraminidase inhibitor and works by stopping viral replication.

Zanamivir was approved for medical use in the United States in 1999. One course of treatment in the United States costs about 68 USD as of 2021. This amount in the United Kingdom costs the NHS about £16. The injectable form is available in Europe.
