First of all, it is recommended to go to the hospital to check to confirm whether there is an infection, do a culture to see what kind of bacteria and what drugs they are sensitive to before using the medication. Although most UTIs can be treated by cephalosporin antibiotics to fight the infection, really do not want to go to the hospital, choose carefully, according to the severity of the UTI to choose different levels of cephalosporin antibiotics. For example, the white blood cells in the urine routine is less than or equal to a plus sign proves that it is a mild UTI and can be treated with a generation of cephalosporin antibiotics. If the white blood cell count in the urine routine is equal to two plus signs, which proves that the UTI is moderate, you can use second generation cephalosporin antibiotics such as cefuroxime for anti-infection treatment. If the white blood cell count in the urine routine is greater than or equal to three plus signs, which proves that the UTI is severe, you can use third generation cephalosporin antibiotics such as cefdinir and ceftriaxone for anti-infection treatment.
