Contemporary management of chronic persistent cough

A chronic persistent cough is one that lasts longer than eight weeks in a patient without known chronic pulmonary disease. These patients may experience prolonged frustration, guilt and self-imposed social isolation, besides risking the medical and surgical complications of recurrent coughing episodes, if the cause of their cough is not quickly established and treated. A comprehensive discussion of the management approach to this problem with reference to the recent literature is presented.
