What is Relenza?

Relenza is an FDA (U.S. Food and Drug Administration) approved antiviral drug manufactured by GlaxoSmithKline. Relenza (zanamivir) inhalation powder is an influenza neuraminidase inhibitor used for the treatment of influenza virus (flu virus) due to influenza A and influenza B virus in adults and pediatric patients 7 years of age and older who have had symptoms for no longer than 2 days.

Relenza is not recommended for the treatment or prophylaxis of influenza in people with any breathing problems or for the treatment of people in nursing homes. It is not an alternative to yearly influenza vaccinations (also known as the flu vaccine and flu shot).

What doses of Relenza are available?

Relenza is available in blisters containing oral inhalation powder on a Rotadisk for inhalation via a Diskhaler, in the following doses: 5 mg.

Relenza should be initiated as soon as possible after flu symptoms appear. Use 2 inhalations twice per day for 5 days. On day 1, space your doses at least 2 hours apart. On subsequent days, space doses are at least 12 hours apart. For the prevention of flu symptoms use 2 inhalations every 24 hours for 10 to 28 days. If you miss a dose use the medicine as soon as you can but skip the missed dose if your next dose is due in less than 2 hours.

Do not use a nebulizer or ventilator to give this medicine. If you are using a bronchodilator at the same time as Relenza, use the bronchodilator first. Store at room temperature away from moisture and heat.

Always speak with a healthcare professional about any changes to your dose so they can monitor and evaluate your condition.
