The flu is a respiratory infection that can cause symptoms such as fever, chills, aches and pains, cough, and sore throat. The flu can range from mild common cold symptoms, to the typical flu symptoms described above, to life-threatening pneumonia and other complications, including secondary bacterial infections.
The antiviral medicines oseltamivir and zanamivir are used to prevent and treat influenza A and B infections. They can reduce the severity and shorten the duration of flu symptoms. Amantadine and rimantadine have been used to help prevent and treat the flu caused by influenza A (but not influenza B) infection. But for the past few years the U.S. Centers for Disease Control and Prevention (CDC) has advised doctors not to use amantadine or rimantadine to treat or prevent the flu. 5 These medicines have not worked against most types of the flu virus.
