Easy-to-use powder to treat and prevent the flu.
Relenza inhalation powder is a flu medication. It’s used to treat the flu if you’ve already caught it or prevent it if you’re at increased risk of getting it.
Answer a few questions about your health, and our clinical team will recommend treatments tailored to you. Order Relenza inhalation powder online and we’ll send it to your doorstep with next-day delivery from our licensed pharmacy.
Relenza is a powder that can treat and prevent flu (or an influenza virus infection to give it it’s proper name). It’s effective at reducing flu symptoms and speeding up your recovery. You can also take it to lower your chances of catching flu if someone in your household or close community has the virus. Relenza inhalation powder can be used in adults and children older than 5.
Relenza is an inhalation powder (that you need to breathe in) specifically designed to target the flu virus inside your lungs. Swallowing the powder won't work as well, as it won't be properly absorbed by your body.
While Relenza is effective for flu, it won't help with colds or other viral infections like coronavirus. Also, it's not a replacement for the flu vaccination. If you’re not sure if Relenza is the best option for you, speak to our clinical team and ask for their advice.
Relenza inhalation powder contains zanamivir as the active ingredient. It’s an antiviral and works by inhibiting the neuraminidase enzyme found in both influenza type A and B viruses.
Zanamivir is a type of medicine called a neuraminidase inhibitor, which works by blocking the release of new flu viruses from infected cells. This stops the virus from infecting more cells in your body and helps to stop the spread of the infection in your respiratory tract. It gives your immune system the chance to fight off the virus that’s still present in your body.
There’s only one dose of Relenza inhalation powder, which contains 5mg zanamivir per dose.
It’s a powdered medicine that comes in blisters on a foil disk (called a Rotadisk). Each blister contains one dose, which you need to load into the Diskhaler device, which comes together with the powder.

Relenza is a powdered medicine that you breathe into your lungs through your mouth, using the Diskhaler device. The powder is found in small pockets or blisters on a foil disk (called a Rotadisk) that you load into the Diskhaler, which is included in the package as well.
Here are the steps you need to follow to use Relenza inhalation powder correctly:
The amount of Relenza you use depends on whether you already have the flu or you want to prevent it.
Relenza is intended to be used for adults and children aged 5 years or older. If your child is younger than 5, reach out to our clinical team, and they'll suggest a suitable alternative for you.
Make sure to use this medicine exactly as your clinician instructed you. Always check with them how to use it if you’re not sure.
If you have the flu, start using Relenza as soon as you notice symptoms. For adults, that's within 48 hours after the first symptoms, and for children within 36 hours.
To prevent getting the flu from someone in your household, begin using Relenza within 36 hours of contact with them, both for adults and children.
If there's a flu outbreak near you, start taking Relenza as soon as possible. Get in touch with our clinical team for further advice.
If you accidentally take too much Relenza inhalation powder, it’s best to seek medical advice. If you forget to take a dose, take it as soon as you remember, unless it's close to your next scheduled dose. Avoid taking a double dose to make up for the skipped one.
