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.
For information about coughs in children, see the topic Coughs, Age 11 and Younger.
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 as:
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 causes of a nonproductive cough, such as:
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 antibiotic-resistant bacteria.
A careful evaluation of your health may help you identify other symptoms. Remember, a 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.
Cough preparations may help your cough. Avoid cold remedies that combine medicines to treat many symptoms. It is generally better to treat each symptom separately. There are two kinds of cough medicines: expectorants and suppressants.
