From the Guidelines
For elderly patients with recurrent UTIs resistant to multiple antibiotics including Ceftin, Cefdinir, Augmentin, Levofloxacin, and Ciprofloxacin, empiric treatment should focus on alternative antibiotics with different mechanisms of action, such as nitrofurantoin or fosfomycin, considering the patient's renal function and potential drug interactions, as suggested by the most recent guidelines 1. Given the prevalence of comorbidities and polypharmacy among older people, treatment selection should take into account potential drug interactions and contraindications, such as impaired kidney function, making fluoroquinolones generally inappropriate for this population 1. Some key points to consider in the management of UTIs in elderly patients include:
- The use of nitrofurantoin (Macrobid) 100mg twice daily for 5-7 days as first-line therapy, provided the patient has adequate renal function (creatinine clearance >30 mL/min) 1.
- Fosfomycin (Monurol) 3g single-dose sachet as an effective alternative if nitrofurantoin is contraindicated 1.
- Intravenous options like ertapenem 1g daily or meropenem 1g every 8 hours for more severe infections or patients with impaired renal function 1.
- The importance of obtaining a urine culture to guide definitive therapy based on susceptibility results, given the extensive resistance pattern 1.
- Consultation with an infectious disease specialist is advisable due to the complexity of the case and the need for personalized treatment 1.
- Prevention strategies, including adequate hydration, proper hygiene, and consideration of vaginal estrogen therapy in postmenopausal women, should also be implemented to reduce the risk of recurrent UTIs 1.

Empiric Antibiotic Treatment for Elderly with Recurrent UTIs
The treatment of recurrent Urinary Tract Infections (UTIs) in the elderly, especially when resistant to commonly used antibiotics like Ceftin (Cefuroxime), Cefdinir, Augmentin (Amoxicillin-Clavulanate), Levofloxacin, and Ciprofloxacin, requires careful consideration of alternative antibiotic options.
Guidelines for Empiric Antibiotic Treatment
- For acute uncomplicated bacterial cystitis in otherwise healthy adult nonpregnant females, recommended first-line empiric antibiotic therapies include a 5-day course of nitrofurantoin or a 3-g single dose of fosfomycin tromethamine 2, 3.
- Fosfomycin and nitrofurantoin are also effective against UTIs caused by AmpC-β-lactamase-producing organisms and ESBLs-producing Enterobacteriaceae 2, 3.
- For patients with risk factors for antibiotic resistance, such as residence in nursing homes, male gender, recent hospitalization, or recurrent UTIs, Piperacillin/Tazobactam may be a better choice for empiric therapy compared to fluoroquinolones, cephalosporins, or gentamicin 4.
- In cases of carbapenem-resistant Enterobacteriaceae (CRE), treatment options include ceftazidime-avibactam, meropenem/vaborbactam, imipenem/cilastatin-relebactam, and fosfomycin 2, 3.
Considerations for Antibiotic Resistance
- The use of fluoroquinolones for empiric treatment of UTIs should be restricted due to increased rates of resistance 2, 3, 5.
- Local susceptibility patterns and risk factors for antibiotic resistance should be considered when selecting empiric antibiotic therapy 4.
- Monitoring local resistance rates and adjusting empiric therapy accordingly is crucial to combat antibiotic resistance 4.
