The latest Cochrane Review reveals there is no solid evidence to support the effectiveness of Tamiflu and Relenza, commonly used medications to fight or prevent influenza symptoms. Dr. David Tovey, editor in chief at Cochrane, writes, “Initially thought to reduce hospitalizations and serious complications from influenza, the review highlights that Tamiflu is not proven to do this, and it also seems to lead to harmful effects that were not fully reported in the original publications. This shows the importance of ensuring that trial data are transparent and accessible.” Similar results were found regarding Relenza.
