QuickFacts on Antivirals
People in high risk groups should talk to their health care provider as soon as possible if they think they may have the flu because they have a greater chance of getting serious flu complications than other persons. Flu antiviral drugs can make you feel better, shorten the time you are sick, and prevent serious flu complications, especially if treatment is begun within 2 days of getting sick. Flu antiviral drugs must be prescribed by a physician.
