If the flu is diagnosed within 48 hours of when symptoms begin, especially if you are high risk for complications, antiviral medications may help shorten the length of symptoms by approximately a day.
In the past, doctors commonly prescribed the antiviral medications amantadine and rimantadine to treat type A influenza. But in January 2006, the U.S. Centers for Disease Control and Prevention announced that neither drug should be used for such treatment because of growing resistance to the drugs. Instead, the agency recommended using oseltamivir (Tamiflu) or zanamivir (Relenza), which are active against both influenza A and B. Each of these medicines has different side effects and affects different viruses. Your doctor will determine which one is best for you.
Treatment is usually not necessary for children, but if the illness is diagnosed early and the patient is at risk of developing a severe case, it can be started. Oseltamivir is the best choice for children. It is available in a liquid formulation and may be easier to give to the child than zanamivir, which is given by inhaler and is not FDA-approved for children under age 12. Treatment will only help if started early and only if the illness is actually influenza. It will not help treat a regular cold.
