Relenza (zanamivir) in an inhalation powder that is effective in both treating and possibly preventing the flu virus. Just like with Tamiflu, it can only be prescribed by a physician and you have to take it early on in the course of the disease for it to be effective. I would recommend reading through both of the websites of relenza and tamiflu to familiarize yourself with the possible treatments of the flu virus and then discussing them with your physician should you or a family member get the flu.
One of the main differences of Relenza is the delivery method and I would encourage readers to watch these videos.
