Cough is an essential component for lung health maintenance, but persistent or excessive cough ceases to be protective, is bothersome, and adversely affects quality of life. Although cough is associated with a variety of diseases, the duration of cough helps narrow the potential etiologies for cough symptoms. The presence of dyspnea, red flag symptoms, and/or symptoms suggestive of acute bacterial rhinosinusitis indicates the need for referral to the patient’s primary care physician. Treatment trials (eg, intranasal corticosteroids, first-generation antihistamines, treatments for gastroesophageal reflux disease) can help rule out common causes of chronic cough.
