The Basics: Flu Medicine
Is there medicine that can treat the flu?
Yes. If you get sick with the flu, your doctor may prescribe medicines called antiviral drugs. Antiviral drugs can help you feel less sick and shorten the time that you’re sick. They can also help prevent serious flu complications.
If you’re at high risk for serious flu complications and you get flu symptoms, tell your doctor about your symptoms right away.
Antiviral drugs work best if you start taking them in the first 2 days after you get sick. But they may still help if you take them later on, especially if you’re very sick.
