Upper-airway cough syndrome (postnasal drip)?,”A patient’s cough that started after a recent URI, that occurs primarily at night, and is without expectoration is most consistent with upper-airway cough syndrome (postnasal drip). In some patients, postnasal drip can be “”silent”” without the classic presentation (eg, liquid dripping into the back of the throat, frequent throat clearing). The best diagnostic approach is to treat empirically with an oral first-generation antihistamine (eg, chlorpheniramine) or combined antihistamine-decongestant (eg, brompheniramine and pseudoephedrine). Patients who do not respond after 2-3 weeks may require further investigation (eg, PFTs, Chest x-ray, CT of the chest) or empirical sequential therapy for GERD, cough-variant asthma, chronic sinusitis
