If you often have a dry cough, no phlegm and an itchy throat, first consider whether it is caused by acute and chronic pharyngitis. Patients with acute and chronic pharyngitis can take throat clearing drops and use medications such as Golden Throat Health Spray for treatment. Long-term dry cough, no phlegm and itchy throat should also be alerted to cough variant asthma, which is an airway hyperresponsiveness disease and can be treated with drugs such as Shunyerin. If you have frequent attacks, you can also use a spray to relieve airway hyperresponsiveness for treatment. Dry cough, no phlegm, and itchy throat also include postnasal drip or reflux esophagitis. Postnasal drip is most often seen in patients with chronic rhinitis and should be treated for rhinitis. The acid reflux caused by reflux esophagitis can burn the throat, causing irritation and dry cough.
