here is your answer.....

Antibiotics are medicines used to treat infections caused by bacteria. Antibiotics don't workagainst infections caused by viruses, such as colds and flu. So there's no point taking antibioticsto treat a cold or flu, and no point asking your doctor to prescribe them for a cold or flu.
