Relenza is a prescription medication used to treat influenza, commonly known as the flu. It belongs to a class of drugs called neuraminidase inhibitors, which work by blocking the action of the neuraminidase enzyme in the influenza virus. By doing so, Relenza helps to reduce the severity and duration of flu symptoms, as well as decrease the risk of complications such as pneumonia.

It is important to note that Relenza is not a substitute for the flu vaccine, but rather a treatment option for those who have already contracted the virus. It is most effective when taken within 48 hours of the onset of symptoms, so it is important to seek medical attention promptly if you suspect you have the flu.

Relenza is available as a powder that is inhaled through the mouth using a special device called a Diskhaler. This method of delivery allows the medication to reach the lungs directly, where it can be most effective in combating the virus.

As with any medication, Relenza may cause side effects in some individuals. Common side effects include nausea, vomiting, diarrhea, and cough. If you experience any severe or persistent side effects, it is important to contact your healthcare provider.

Overall, Relenza is a valuable tool in the treatment of influenza and can help to alleviate symptoms and reduce the risk of complications. If you have any questions or concerns about this medication, do not hesitate to speak with your healthcare provider.
