Cefixime can be applied in the treatment of UTIs. The oral antimicrobial agent of cephalosporin III has good therapeutic effects on Gram-negative bacilli and Gram-positive cocci, such as Escherichia coli and Klebsiella, which are common infections of the urinary tract. It is also effective against β-lactamase-resistant bacteria and can be used as the first choice for empirical use. To use cefixime capsules, patients must have no history of allergy to cephalosporins. If never taken orally, a test for cephalosporin needs to be done at a hospital before taking it, otherwise an allergic reaction may occur. Cefixime capsule is less effective in treating specific pathogenic bacteria, such as UTI due to mycoplasma or chlamydia infection, or UTI due to fungal infection, Cefixime cannot be chosen for treatment, and other antimicrobial agents need to be adjusted for treatment. During the medication period, you need to drink more water and urinate more often. If you have the conditions, it is best to go to the hospital for urine routine or smear culture of secretions and other examinations to clarify the pathogenic bacteria and then select the medication for treatment. If there is no condition to do the above examination, empirical medicine can choose cefixime for treatment.
