oseltamivir

Oseltamivir, commonly known as Tamiflu, is an antiviral medication used to treat and prevent influenza (flu). It works by inhibiting a viral enzyme called neuraminidase, which helps the flu virus spread within the body. When taken promptly, usually within the first couple of days of symptoms, oseltamivir can reduce the severity and duration of flu symptoms. It is also used to prevent flu in people who have been exposed to the virus. The medication is available by prescription and should be used under medical supervision for best results.
