How Long Does Tamiflu Take to Work? - Genericcures

An antiviral medicine called Tamiflu (oseltamivir) is frequently used to treat influenza (flu) infections. Taken as soon as flu symptoms appear, Tamiflu usually becomes effective in 24 to 48 hours. It functions by preventing the influenza virus from becoming active, which lessens the intensity and duration of symptoms including fever, coughing, sore throats, and body aches. Tamiflu is best taken early, particularly during the first 48 hours after symptom onset, even though it can help reduce symptoms and decrease the illness's duration. Nonetheless, if initiated later in the course of the illness, it can still be somewhat beneficial. Even if symptoms subside before taking the entire term of Tamiflu as directed by a doctor, it's still crucial to follow up on the prescription. To successfully treat flu symptoms, additional supportive measures including rest, fluids, and over-the-counter medications may also be suggested.
