At times, these anti-viral medications will be prescribed within 48 hours of getting the flu, in the hope of decreasing the severity and duration of flu symptoms. Effective against both major strains of the flu, influenza A and B, the medication is inhaled through the mouth as a powder spray. A similar medicine in pill form is expected to be approved soon. The one drawback to the medications is that they have to be taken within the first day or two of the onset of symptoms to be effective. Contrary to popular belief, antibiotics will not cure colds and flu.
Antibiotics are only effective against bacteria, which are very different from viruses.

Prevention remains the best way to avoid colds and flu. Check out these other articles in the HealthAtoZ Cold and Flu Condition Forum. And Flu Home Page.
