Although chronic cough in adults can be caused by many etiologies, four conditions account for most cases: upper airway cough syndrome, gastro-esophageal reflux disease, also known as laryngo- pharyngeal reflux disease, bronchial asthma, and non-asthmatic eosinophilic bronchitis. All patients should be evaluated clinically with spirometry, and empiric treatment should be initiated. Other potential causes include angiotensin-converting enzyme inhibitor use, environmental triggers, tobacco use, chronic obstructive pulmonary disease, and obstructive sleep apnea. Chest radiography can rule out concerning infectious, inflammatory, and malignant thoracic conditions. Patients with refractory chronic cough should be referred to a pulmonologist or otolaryngologist in addition to a therapeutic trial of gabapentin, pregabalin, and psychotherapy.
