Both amoxicillin and cephalosporin can be used to treat bacterial pneumonia, but the specific choice should be made in conjunction with bacterial culture and drug sensitivity tests. Ineffective for viral, fungal, and Mycoplasma pneumonia. 1. Amoxicillin: It is suitable for patients with pneumonia caused by Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus, hemolytic streptococcus and other sensitive bacteria, and its common adverse reactions are nausea, vomiting, abdominal pain, rash, etc. Penicillin allergic patients should be cautious of using amoxicillin, and it is easy to produce drug resistance with long-term use. 2. Cephalosporin: common cefuroxime, cefradine, ceftriaxone and so on. Generally for Pseudomonas aeruginosa, Haemophilus influenzae, Klebsiella, Escherichia coli, pneumococcus, staphylococcus and other sensitive strains of infection caused by pneumonia patients can choose cephalosporins. The common adverse reactions of cephalosporins are allergic reactions, gastrointestinal reactions, renal impairment, coagulation abnormalities, etc. The use of cephalosporins must have a clear indication, and alcohol consumption is prohibited during the use of the drug. When you have pneumonia, do not judge the use of drugs on your own, improper selection of drugs is not only easy to cause antibiotic resistance, but also allergic reactions to drugs may occur and cause adverse consequences. The above drugs should be used under the guidance of a physician.
