What should I know before taking Tamiflu?
Tamiflu’s safety and effectiveness have not yet been assessed in people with chronic heart or lung disease, kidney failure, or in people with underlying high-risk medical conditions. Tamiflu has not been shown to treat flu-like illnesses caused by any viruses other than influenza A and B. Other kinds of infections similar to influenza (or that occur along with influenza) need different types of treatment. Tamiflu is not recommended for treatment or prevention of the flu in pediatric patients less than 1 year of age.
