Watchful Waiting
In most healthy people, the flu will go away in 5 to 7 days, although fatigue can last much longer. Although you may feel very sick, home treatment is usually all that is needed. If it is flu season, you may just want to treat your symptoms at home. Watch closely for symptoms of a bacterial infection, such as nasal drainage that changes from clear to colored after 5 to 7 days and symptoms that return or get worse.
Early treatment (within 48 hours of your first symptoms) with antiviral medications may reduce the severity of influenza. However, it is not certain whether antiviral medications can prevent serious flu-related complications.3 Babies, older adults, and people who have chronic health problems are more likely to have complications from the flu, and they may need to see a doctor for care beyond home treatment. Also, not all antiviral medicines work against all strains of the flu. Talk to your doctor if you think you may need an antiviral medicine.4
Call your doctor if you think your symptoms are caused by something other than the flu.
