The length of treatment for Klebsiella pneumoniae infection is approximately 1 to 4 weeks. The duration of treatment for Klebsiella pneumoniae infection is closely related to the severity of the infection, the location of the infection, the formation of drug-resistant organisms, and the presence or absence of complications. 1. For pneumonia formed after infection, it is usually necessary to use third-generation cephalosporins (e.g. ceftazidime, etc.) antibiotics, or combined use of fluoroquinolones (e.g. levofloxacin, etc.), aminoglycoside antibiotics (e.g. streptomycin, etc.), etc., to carry out anti-infective treatment, and the treatment cycle of antibiotics is mostly about two weeks. 2. For patients with serious infections or the formation of drug-resistant bacteria, the anti-infection time needs to be increased appropriately. 3. For patients with septicemia after Klebsiella pneumoniae infection, the anti-infection time usually needs to be more than three weeks. 4. If a lung abscess is formed after Klebsiella pneumoniae lung infection, the anti-infection time should be further extended at this time, generally need to exceed four weeks. Therefore, the treatment time after the infection of Klebsiella pneumoniae, according to the specific situation of the development of the disease to determine the time needed for treatment, the above drugs need to follow the doctor’s instructions.
