View full FDA label ↗Tamiflu is a medication used to treat and prevent influenza, commonly known as the flu, in people aged 2 weeks and older. It works by stopping the flu virus from spreading in the body, helping to reduce the severity and duration of symptoms. For treatment, adults and adolescents typically take 75 mg twice a day for 5 days, while younger children may have a dose based on their weight. It's important to note that Tamiflu is not suitable for individuals with severe kidney problems who are not on dialysis. Additionally, if you are taking probenecid, it may increase the levels of Tamiflu in your body, so your doctor may need to adjust your dose.
