If pneumonia is caused by a bacterial infection, oral cephalosporin antibiotics are likely to be effective. However, if the pneumonia is more pronounced, there are obvious symptoms such as chills, high fever, coughing, coughing, and even chest tightness and suffocating wheezing. This is when large swaths of pneumonia are treated purely by oral cephalosporin antibiotics, whose corresponding antibacterial strength is not sufficient, and most of these require intravenous application of antibiotics. Oral cephalosporin antibiotics, its bactericidal effect is weaker than intravenous application of antibiotics, even if the intravenous application of ordinary cephalosporin, it is likely to play a role in controlling the disease. Therefore, if the pneumonia is heavy, it is recommended to treat it by intravenous medication and to apply phlegm-reducing drugs along with intravenous medication. When you have pneumonia, you can try to take cephalosporin if the symptoms are relatively mild, but if the symptoms are slightly more severe, hospitalization is recommended.
