Oseltamivir (Tamiflu)

Oseltamivir, commonly known by its brand name Tamiflu, is an antiviral medication used to treat and prevent influenza (the flu). It works by inhibiting the flu virus's ability to spread in the body, helping to reduce the severity and duration of symptoms. Typically prescribed for those at high risk of flu complications, it is most effective when taken within the first few days of symptom onset. While it can alleviate suffering from the flu, it is not a substitute for vaccination, which is the best way to prevent flu infection.
