Recurrent urinary tract infections in the elderly can be cured by using drugs such as Ofloxacin, Norfloxacin, Cefaclor, Serodosin and so on under the guidance of the doctor, but there is still a possibility of recurrence, and it is necessary to pay attention to daily care. The common cause of recurrent urinary tract infections in the elderly is suffering from non-specific pyelonephritis, cystitis and other diseases, and it may also be caused by prostate hyperplasia and hypertrophy in male elderly, and it may also be caused by the decrease of hormone level in female elderly. Patients need to actively treat the primary disease, and commonly used drugs include quinolones such as Ofloxacin, Norfloxacin, Ciprofloxacin, and cephalosporins such as Cefaclor, Cefuroxime, and other cephalosporins. If male seniors are caused by an enlarged and hypertrophied prostate, they can be treated with medications such as Serodosin. Female seniors with decreased hormone levels can be treated with estrogen supplements. As the patient will still have the possibility of recurrence, daily attention should also be paid to appropriate physical exercise to improve their immunity. Diet should be light, rich and easy to digest, and also pay attention to drink more water.
