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.
Reduce the severity and duration of symptoms
caused by infection with influenza A or B virus.
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.
If medicines are not used, contact your doctor if symptoms
of a complication develop.
