Influenza, commonly called the "flu," is a contagious viral infection that affects the respiratory system—your nose, throat and lungs. Symptoms of the flu can include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue. Some people may also have vomiting and diarrhea.

Sick with Flu? Early Antiviral Treatment is Important

If you have a high risk condition (see below) and you get the flu, early treatment with flu antiviral medications is important. Antiviral drugs are prescription medicines that can be used to treat the flu. Rapid treatment with antiviral drugs in someone with a high risk condition can mean the difference between experiencing mild symptoms at home instead of suffering a very severe illness that could result in a hospital stay. Studies show that these drugs work best when they are started within 2 days of getting sick. However, starting them later can still be helpful, especially if the sick person has a high risk health condition or is very sick from the flu.

Antiviral medicines are not a substitute for vaccination. Annual flu vaccination is the first and best way to prevent the flu, but if you do get sick with the flu, antiviral medicines are a second line of defense to treat the flu. Antiviral medicines can be prescribed by a doctor to help make flu illness milder and shorten the time you are sick. Data also show that antiviral drugs may prevent serious flu complications. If you have a high risk medical condition and develop flu symptoms, check with your doctor promptly.

High Risk
