The best prevention during flu season is following the standard advice: Get a flu shot and wash your hands before eating or touching your face.
But if you do get the flu, certain antiviral medications like Tamiflu (oseltamivir) and Relenza (zanamivir) are still available as a treatment, according to the Harvard Health Letter.
These antivirals must be taken within two days of the onset of symptoms to be effective and might speed recovery by one or two days.
In June, the World Health Organization removed oseltamivir from its list of essential medicines, citing low effectiveness in clinical trials.
However, this drug and others in the antiviral category do help some people if taken early enough. Older people and those with chronic lung, heart or kidney disease or compromised immune systems would be a candidate for the flu drugs.
