Cephalosporin and azithromycin are not recommended for viral colds because the pathogens that cause viral colds are viruses, and cephalosporin and azithromycin do not fight viruses. Cephalosporin is a beta-lactam antibiotic that kills pathogenic bacteria such as Streptococcus pneumoniae, while azithromycin is a macrolide antibiotic that kills pathogenic bacteria such as Mycoplasma. Both are commonly used in the treatment of pneumonia, urethritis, skin infections and other diseases caused by the above sensitive bacterial infections, but neither has antiviral efficacy. In addition, the abuse of cephalosporin has rashes, drug rashes, dizziness, neutropenia and other adverse reactions, and penicillin allergy is prohibited, can not drink alcohol after taking; abuse of azithromycin has liver damage, Q-T interval prolongation, dizziness, nausea, and other adverse reactions, and allergic to the drug components are prohibited, liver insufficiency should be used with caution. Abuse of drugs not only can not treat colds, but will increase the toxic side effects, so it is not recommended. Viral cold is a self-limiting disease, even without treatment, most patients can rely on their own immune function to gradually recover. Patients are advised to drink more water, take more rest, and open the windows for ventilation. When symptoms such as fever, nasal congestion and cough are severe, it is recommended to go to the hospital.
