When are antiviral drugs appropriate?
Antiviral drugs may be recommended for both the treatment and prevention of influenza. They work best if taken within 48 hours of the start of your flu symptoms, but they can offer benefits when taken later as well.

Who should take antivirals?
The CDC recommends that everyone at risk for flu, like pregnant women, those with asthma, diabetes, or heart disease start antiviral treatment as soon as they experience flu symptoms. Keep in mind, the CDC also advises those individuals to get vaccinated first, as it is the most effective way to prevent the flu.
