There are many kinds of cough syrups for dry cough, the most effective ones are those containing codeine and those containing opium, such as cough syrup, strong lozenges, and some combinations. Although these are effective, they can cause phlegm deep in the lungs that cannot be discharged because of the coughing bouts. Although it is a dry cough, if the contents of the lungs cannot be discharged, it will have a great impact on the recovery of the disease, and even if the symptoms get better in the future, it may leave something bad in the lungs. Other than that, when you have a dry cough because you don’t know if there is phlegm, you can use phlegm medicine as a cough syrup. When coughing, drink a small sip, then cough again and drink a small sip, with this process phlegm gradually up can also stop the cough. There are also drugs for the throat, such as Golden Fruit Drink Oral Liquid and Niancian, which act on the throat to relieve the symptoms and give great relief to the cough caused by a dry, itchy throat.
