When dry cough with phlegm occurs, the phlegm in this case is often sticky, so the symptoms of dry cough will occur and the phlegm will not be easily coughed up. First of all, it is necessary to use phlegm-thinning drugs for treatment. Clinically, it is more common to use Ambroxol hydrochloride and Ambroterol oral solution, which can promote the dilution of phlegm and make it easier to cough up. In addition, the reason for dry cough with phlegm is the occurrence of infection, and the most fundamental measure to treat dry cough with phlegm is to carry out anti-inflammatory measures against the infection. If it is a bacterial infection, you can take antibiotics to treat it, and if you are not allergic to cephalosporin, you can take cefadroxil to treat it. If it is a viral infection, you can take anti-viral Pudilan Anti-inflammatory Oral Liquid and Blue Scutellaria Oral Liquid for treatment. Another more common cause of dry cough with phlegm is the occurrence of mycoplasma infection, which often requires the use of macrolide antibiotics, such as azithromycin.
