How fast can I make my the flu go away?

Mild Med Effect. If you have true influenza, antiviral drugs such as tamiflu (oseltamivir) may, if taken in the first day or two of the onset may shorten the course a few days at best. Talk to your doctor.
Patience. Flu viruses require time for your immune system to clear. It can take several weeks - often another virus gets established before you clear the first one, making it seem to take over a month to clear up the "flu".
