    Influenza (Seasonal Flu)



    Treatment Overview

    In most healthy people, influenza (flu) will go away in 5 to 7 days. The worst symptoms usually last 3 to 4 days. Home treatment to ease symptoms and prevent complications is usually all that is needed.

    Antiviral medicines may help:

    • Reduce the severity and duration of symptoms caused by infection with influenza A or B virus.
    • Shorten the length of the illness.
    • Control outbreaks of the flu in nursing homes.
    • Reduce the spread of the virus to people at high risk for severe Reference complications of the flu (Reference high-risk groups).
    • Reduce complications from the flu.

    People at high risk of complications are encouraged to contact a doctor within 48 hours of their first symptoms to find out whether they need medicine to shorten the illness. They also should call a doctor to receive medicine if they have been exposed to the flu.
