Coughing is the body's way of removing
foreign material or mucus from the
lungs and upper airway passages or of reacting to an irritated airway. Coughs
have distinctive traits you can learn to recognize. A cough is only a symptom,
not a disease, and often the importance of your cough can be determined only
when other symptoms are evaluated.

children, see the topic

A productive cough produces phlegm
or mucus (sputum). The mucus may have drained down the back of the throat from
the nose or sinuses or may have come up
from the lungs. A productive cough generally should not be suppressed—it
clears mucus from the lungs. There are many causes of a productive cough, such
A nonproductive cough is dry and
does not produce sputum. A dry, hacking cough may develop toward the end of a
cold or after exposure to an irritant, such as dust or smoke. There are many

Many coughs are caused by a viral illness. Antibiotics
are not used to treat viral illnesses and do not alter the course of viral
infections. Unnecessary use of an antibiotic exposes you to the risks of an
allergic reaction and antibiotic side effects, such as
nausea, vomiting, diarrhea, rashes, and yeast infections. Antibiotics also may
kill beneficial bacteria and encourage the development of dangerous

cough is only a symptom, not a disease, and often the importance of your cough
can only be determined when other symptoms are evaluated. Coughs occur with
bacterial and viral respiratory infections. If you
have other symptoms, such as a sore throat, sinus pressure, or ear pain, see
the Related Topics section.

Coughing is your body's way of
removing foreign substances and
mucus from your
lungs and upper airway passages. Productive coughs are often useful, and you
should not try to eliminate them. Sometimes, though, coughs are severe enough
to impair breathing or prevent rest. Home treatment can help you feel more
comfortable when you have a cough.
