The phenomenon of cough, yellow phlegm and cold is due to the bacterial infection of the respiratory system, which requires the use of antibiotics for anti-inflammatory treatment. It is also necessary to observe whether it is an upper respiratory tract infection or a lower respiratory tract infection, and chest CT or plain film examination is required. If it is a simple bacterial infection of the upper respiratory tract, oral antibiotics are better for treatment. For example, if penicillin is not allergic, you can take amoxicillin and clavulanate potassium orally. If the cephalosporins are not allergic to drugs, you can take cefixime orally for anti-inflammatory treatment. If lower respiratory tract infection occurs, it needs to be hospitalized for infusion treatment. If the cephalosporins are not allergic to drugs, you can infusion ceftriaxone or cefoperazone. If penicillin is not allergic, penicillin can also be given intravenously for anti-inflammatory treatment. For the cough with yellow phlegm, it is necessary to use cough and expectorant drugs at the same time. For cough with yellow phlegm, compound fresh bamboo juice, fresh bamboo juice or Feili cough mixture are better.
