MedDataToolRelenza is a medication used to treat and prevent influenza (the flu) in people aged 5 years and older. It works by stopping the flu virus from spreading in the body. The medication is taken as an inhaled powder, with a starting dose of 10 mg twice daily for 5 days for treatment, or 10 mg once daily for 10 to 28 days for prevention, depending on the situation. It's important to note that Relenza should not be used by individuals with breathing problems, as it can cause serious breathing issues. Additionally, if you are using an inhaled bronchodilator, you should take that medication before using Relenza.
