Patients with urinary tract infections can take cefprozil tablets, which are an oral cephalosporin preparation that has a certain bactericidal effect on common infections in the urinary tract and can therefore be used as an oral treatment for urinary tract infections. However, cephalexin tablets require cephalosporin skin testing and should not be taken by patients with cephalosporin allergy. Some patients with urinary tract infections may have drug-resistant bacteria, so in principle, it is best to do drug sensitivity tests and urine culture tests before selecting drugs, so as to achieve targeted drug selection. If the symptoms do not improve after more than 3 days of continuous medication, it is necessary to go to the hospital for further examination or to adjust the medication if necessary. Except for allergy, cephalosporin will not cause other types of side effects to patients. It is recommended to go to the hospital after taking a course of medication to review the urine routine to understand the recovery of infection and whether other medications still need to be adjusted for treatment at a later stage.
