The first thing that I would like to talk about is the difference between cefradine and levofloxacin, the two antibiotics that are used for UTIs. Cefradine belongs to the cephalosporin class of antibiotics also belongs to the generation of cephalosporin, relatively speaking, the effect will be a little bit worse, while levofloxacin belongs to the second generation of quinolone antibiotics, relatively speaking, the treatment of urinary tract infection more effective. If the number of white blood cells in the urine routine is less than one plus is a mild urinary tract infection, you can take cefradine for anti-infection treatment, if the white blood cells in the urine routine is greater than or equal to two plus proves that it is a moderate to severe urinary tract infection, you need to use levofloxacin for anti-infection treatment.
