When are antibiotics not needed?
Antibiotics are not needed for and won’t work against viral infections, such as cold, the flu or mono (mononucleosis). Every time you take antibiotics when you don’t need them, you increase the chance you someday will get an illness caused by resistant bacteria. You should not ask your doctor to give you or your children antibiotics for a viral illness. Instead, ask your doctor what you can do to feel better while your body fights the infection.
