What is chronic cough?

For adult patients, chronic cough is a cough that lasts for >8 weeks and is estimated to impact ~5% of the US population.*1,2

When cough persists >8 weeks, consider further evaluation.1

Cough as a medical problem can be evaluated by its duration, characteristics, severity, etiology, pathophysiology, or treatment response.3

Investigation of cough seeks to identify and treat underlying conditions.1

*Based on a cross-sectional study of 74,977 adults in the United States who completed a 2018 National Health and Wellness Survey, 4.9% of respondents self-reported experiencing chronic cough in the prior 12 months.2


Common underlying conditions

Chronic cough is often associated with asthma, GERD, UACS (postnasal drip), and/or NAEB.1,4

In some cases, cough persists even after underlying conditions have been treated, or an underlying condition cannot be identified.5

GERD, gastroesophageal reflux disease; UACS, upper airway cough syndrome; NAEB, nonasthmatic eosinophilic bronchitis.


If chronic cough persists, consider refractory or unexplained chronic cough

Refractory or unexplained chronic cough is a chronic cough that persists despite appropriate treatment of an underlying condition or for which no underlying condition has been identified despite a thorough clinical evaluation.1,5

In patients with refractory or unexplained chronic cough,
cough could be considered as a medical condition rather than a symptom.6
