From the Guidelines
For a UTI requiring treatment equivalent to ceftriaxone, the recommended oral alternative is cefixime, with a typical adult dose of 400 mg once daily for 7-14 days, depending on the severity of the infection, as supported by the study 1.
Key Considerations
- Cefixime, like ceftriaxone, is a third-generation cephalosporin with good coverage against common UTI pathogens, including E. coli, achieving high urinary concentrations, making it effective for urinary tract infections 1.
- If cefixime is unavailable or not tolerated, alternatives such as ciprofloxacin (500 mg twice daily) or trimethoprim-sulfamethoxazole (160/800 mg twice daily) can be considered, but these should be based on local resistance patterns and individual patient factors, as suggested by 1 and 1.
- It's crucial to obtain a urine culture before starting antibiotics if possible, to ensure the chosen antibiotic is appropriate for the specific pathogen, as recommended by 1 and 1.
- Patients should be advised to complete the full course of antibiotics even if symptoms improve, and to increase fluid intake to help flush out the urinary system.
Additional Guidance
- The choice of antibiotic should consider local resistance patterns, with fluoroquinolones being a preferred option in areas with low resistance rates, as noted in 1 and 1.
- In regions with high fluoroquinolone resistance, an initial dose of a long-acting parenteral antimicrobial, such as ceftriaxone, may be necessary, as suggested by 1 and 1.
- The most recent guidance from 1 emphasizes the importance of short-course therapy for uncomplicated UTIs, which can include fluoroquinolones or trimethoprim-sulfamethoxazole, but always considering local resistance patterns and patient-specific factors.

- It is available as an oral suspension and capsule for adults and pediatric patients six months of age or older.
From the Research
Oral Equivalent of Ceftriaxone for Treating UTI
The oral equivalent of Ceftriaxone for treating Urinary Tract Infections (UTI) can be considered based on the following points:
- Cefpodoxime is mentioned as an empiric therapy option in the treatment protocol for UTIs, alongside ceftriaxone, in a study published in 2020 3.
- Cefixime is suggested as a suitable empiric agent for the treatment of UTI with oral antibiotics alone, even in young children with pyelonephritis, according to a study from 1999 4.
- The choice of empirical antibiotic therapy should be based on the stratification into complicated and uncomplicated, as well as upper and lower infections, and on specific risk factors, as stated in a 2020 review of current guidelines for the treatment of UTIs 5.
- A study from 2002 compared the efficacy and safety of ertapenem with ceftriaxone, followed by appropriate oral therapy, for the treatment of complicated UTIs in adults, and found that ertapenem was as effective as ceftriaxone, with a similar overall safety profile 6.
- The preferred oral antibiotics for the treatment of uncomplicated UTIs include nitrofurantoin, trimethoprim-sulfamethoxazole, fosfomycin trometamol, fluoroquinolones, and β-lactam agents, according to a 2017 article discussing the pharmacological properties of oral antibiotics for UTI treatment 7.
Key Points to Consider
- The choice of oral antibiotic should be based on the pharmacokinetic characteristics of the molecule to optimize clinical benefit and minimize the risk of antibacterial resistance.
- Cefpodoxime and cefixime are potential oral equivalents of ceftriaxone for treating UTIs, depending on the specific circumstances and patient factors.
- The treatment protocol should be guided by current guidelines and the stratification of UTIs into complicated and uncomplicated cases.
