Chronic cough or a cough that lasts longer than three weeks may be caused by the following:
A chronic cough may be an unusual symptom of asthma. The cough may first appear after a cold or an upper respiratory tract infection. The cough may also start as a "tickle" in the throat. In some people with asthma, laughing or exercise triggers coughing. Other people cough at night while others cough at any time of day without a trigger.
Coughing due to asthma usually does not respond to cough suppressants, antibiotics, or cough drops but will respond to asthma medications. If you have a cough that does not get better on its own within 3 to 6 weeks, see your health care provider.
