Coughing with phlegm that cannot be spit out is in most cases due to sticky phlegm. In this case, you can choose medication according to your own situation, or use phlegm-reducing drugs to solve the problem, as follows: 1) Chinese medicine, such as Chuanbei Loquat Paste, Fresh Bamboo Li Oral Liquid, Lung Power Cough Capsules; 2) Western medicine, such as Ambroxol Hydrochloride Tablets, N-Acetyl Cysteine, Eucalyptus Pinellia Enteric Soft Capsules; 3) Nebulized inhalation drugs, such as Acetyl Cysteine. In addition, you can also choose to take western medicine and Chinese medicine at the same time, or with nebulization, to play a dual role in treating the symptoms and the root cause, so that the phlegm can be more easily diluted out of the body.
