Coughing up blood when coughing requires timely identification of the cause and the use of symptomatic treatment. If the coughing and coughing up blood is caused by infection, azithromycin tablets can be taken to treat it. Azithromycin tablets belong to the macrolide class of antibiotics and are mainly used to treat coughs caused by mycoplasma infections, together with proprietary Chinese medicines that have a clearing effect on the throat, such as Yi Qing granules and Er Ding granules. Active cough suppression is also needed. Commonly used cough suppressants include Chuanbei Loquat Paste, Ambroxol Hydrochloride Syrup, and Orange Red Granules. If the cough and blood cough are caused by lung cancer or bronchial cancer, you need to take hemostatic drugs immediately, such as methotrexate tablets, and at the same time, you also need to take hemostatic drugs to clear heat and cool blood, such as Fuxiang Qing Dai Wan, etc., so that the comprehensive treatment can have better effect.
