Discontinuing Antibiotics for Possible UTI with Negative Urine Culture

Evidence-Based Recommendations for Antibiotic Discontinuation

Antibiotics should be discontinued when urine culture results are negative in patients started on empiric therapy for possible UTI, provided the patient is clinically improving and there is no other infection requiring treatment, as recommended by the American Academy of Pediatrics 1
Discontinue antimicrobial agents when all bacterial cultures are negative at 24-36 hours, the patient is clinically well or improving, and there is no other infection requiring treatment, as recommended by the American Academy of Pediatrics 1
Continuing antibiotics despite negative cultures contributes to antimicrobial resistance, disrupts the patient's microbiome, and increases the risk of adverse drug reactions without providing clinical benefit, according to the American Academy of Pediatrics and the American Urological Association 1, 2

Clinicians should not treat asymptomatic bacteriuria in patients, as recommended by the American Urological Association 2
Treating asymptomatic bacteriuria has been shown to foster antimicrobial resistance and increase the number of recurrent UTI episodes, according to the American Urological Association 3

For well-appearing febrile infants, strong evidence supports discontinuing antibiotics when cultures are negative at 24-36 hours and the infant is clinically well or improving, as recommended by the American Academy of Pediatrics 1, 4

For patients with persistent urinary symptoms despite negative cultures, consider re-evaluation for other causes of symptoms, as recommended by the American Academy of Pediatrics 1
Avoiding classification of patients with recurrent UTI as "complicated" can help prevent the use of broad-spectrum antibiotics with long durations of treatment, according to the American Urological Association 3
