From the Guidelines

Ceftriaxone is indicated for the treatment of complicated urinary tract infections (UTIs) in male patients, particularly when systemic symptoms are present, as stated in the 2024 European Association of Urology guidelines 1. When considering the treatment of a male patient with a UTI, it's essential to differentiate between uncomplicated and complicated infections. Complicated UTIs, which may involve structural or functional abnormalities of the urinary tract, require more aggressive treatment approaches.

  • The European Association of Urology guidelines from 2024 suggest using an intravenous third-generation cephalosporin, such as ceftriaxone, as empirical treatment for complicated UTI with systemic symptoms 1.
  • Ceftriaxone's broad-spectrum activity against gram-negative bacteria, including Escherichia coli, a common cause of UTIs, makes it a suitable option for complicated cases.
  • The dosage and duration of ceftriaxone treatment can vary depending on the severity of the infection and the patient's clinical response, but typical regimens involve 1-2 grams intravenously or intramuscularly once daily for 7-14 days.
  • It's crucial to perform urine culture and sensitivity testing before initiating treatment to guide appropriate antibiotic selection and adjust therapy as needed based on the results.
  • For uncomplicated UTIs in men, oral antibiotics like trimethoprim-sulfamethoxazole or fluoroquinolones might be preferred as first-line treatments, reserving ceftriaxone for more severe cases or when oral therapy is not suitable.

From the FDA Drug Label

Urinary Tract Infections (complicated and uncomplicated) caused by Escherichia coli, Proteus mirabilis, Proteus vulgaris, Morganella morganii or Klebsiella pneumoniae Ceftriaxone is indicated for the treatment of Urinary Tract Infections (UTIs) in males, but only when caused by susceptible organisms such as Escherichia coli, Proteus mirabilis, Proteus vulgaris, Morganella morganii, or Klebsiella pneumoniae 2.

  • Key points:
    • Ceftriaxone is effective against certain bacteria that cause UTIs
    • The drug should only be used to treat infections caused by susceptible bacteria
    • Culture and susceptibility information should be considered when selecting therapy 2

From the Research

Ceftriaxone Indication for Male UTI

  • Ceftriaxone, a third-generation cephalosporin, has been studied for the treatment of urinary tract infections (UTIs) in various patient populations, including men 3, 4, 5.
  • A study published in 2004 compared the efficacy of ertapenem and ceftriaxone for the treatment of complicated UTIs, including those in men, and found that both treatments had similar success rates 3.
  • However, a 2018 study suggested that ceftriaxone treatment of complicated UTIs may be associated with a higher risk of enterococcal re-infection and prolonged hospitalization 4.
  • Another study published in 2014 reviewed the diagnosis and management of UTIs in the outpatient setting and noted that fluoroquinolones, rather than ceftriaxone, are often reserved for more invasive infections 6.
  • A 1985 study compared single-dose ceftriaxone treatment with a standard five-day regimen of trimethoprim-sulfamethoxazole for UTIs and found no significant difference in cure rates between the two groups 5.

Key Findings

  • Ceftriaxone may be effective for the treatment of UTIs in men, but its use should be considered carefully due to the potential risk of enterococcal re-infection 4.
  • The choice of antibiotic therapy for UTIs should be individualized based on patient factors, such as the presence of underlying medical conditions or the risk of antibiotic resistance 6.
  • Ceftriaxone may be an option for the treatment of complicated UTIs, but its use should be guided by clinical judgment and consideration of the potential risks and benefits 3, 4, 5.
