What is the difference between antiviral flu medicines and antibiotics?

Antiviral medicines for flu (pills, liquid, or an inhaled powder) reduce the ability of the flu viruses to make more flu viruses in the body.  Antibiotics kill or stop the growth of bacteria. Most women with the flu will be prescribed an antiviral medicine (Tamiflu® or Relenza®).  But, if the doctor is concerned that a woman also has a bacterial infection, in addition to the flu, an antibiotic may also be prescribed.
