For patients with phlegm due to fire, it is recommended to take oral cough relieving and expectorant drugs, such as Mylian Chuanbei Pipa Ointment, Xianzhuli Oral Liquid, Shedan Chuanbei Oral Liquid, Jizhi Syrup, Eucalyptus Linpin Capsules, Fudosteine Capsules, Ambroxol Hydrochloride Oral Liquid. None of these drugs can effectively dilute sputum and promote sputum excretion. The effect is better for the patients with upper fire and phlegm. When the patient has fire and phlegm, it is necessary to pay attention to whether the patient has inflammation. In addition to the use of antitussive and expectorant drugs, anti-inflammatory treatment is also needed. Only by doing both, can the symptoms of patients be effectively improved and the pain of patients be alleviated. The effect of drug use for patients is not ideal, and they need to go to the hospital in time for chest CT examination to exclude some malignant diseases.
