From the Guidelines
Augmentin should not be the first-line treatment for a UTI due to its inferior efficacy and higher propensity for adverse effects compared to other recommended agents. According to the 2010 update by the Infectious Diseases Society of America and the European Society for Microology and Infectious Diseases 1, beta-lactam agents, including amoxicillin-clavulanate (Augmentin), are appropriate choices for therapy when other recommended agents cannot be used, but they generally have inferior efficacy and more adverse effects compared to other UTI antimicrobials.
Some key points to consider when treating a UTI include:
- Nitrofurantoin monohydrate/macrocrystals and trimethoprim-sulfamethoxazole are recommended as first-line treatments due to their efficacy and minimal resistance 1
- Fosfomycin trometamol and pivmecillinam are also appropriate choices for therapy in certain regions, but may have inferior efficacy compared to standard short-course regimens 1
- Fluoroquinolones, such as ofloxacin, ciprofloxacin, and levofloxacin, are highly efficacious but should be reserved for important uses other than acute cystitis due to their propensity for collateral damage 1
If Augmentin is prescribed for a UTI, a typical regimen is 500 mg (of the amoxicillin component) taken orally every 12 hours, or 250 mg every 8 hours, usually for 3-7 days depending on symptom severity. It's essential to complete the full course of antibiotics, drink plenty of water to help flush bacteria from the urinary tract, and take the medication with food to reduce stomach upset. However, it's crucial to note that Augmentin is not the preferred agent for empirical treatment of acute cystitis, and other recommended agents should be considered first 1.
From the Research
Treatment of UTIs with Augmentin
- Augmentin, also known as amoxicillin-clavulanate, is a potential treatment option for urinary tract infections (UTIs) 2, 3.
- According to a study published in 1987, Augmentin was found to be effective in treating UTIs, including uncomplicated and complicated, recurrent, and nosocomial infections 2.
- Another study from 1982 reported a success rate of about 70% for amoxycillin-resistant organisms when treated with Augmentin 3.
- However, a network meta-analysis published in 2012 ranked amoxicillin-clavulanate as the least effective treatment for UTIs compared to other antibiotics, such as ciprofloxacin and gatifloxacin 4.
- It is essential to note that the effectiveness of Augmentin for UTIs may depend on the specific type of bacteria causing the infection and local susceptibility patterns 5.
Considerations for UTI Treatment
- The recommended first-line empiric antibiotic therapy for acute uncomplicated bacterial cystitis in otherwise healthy adult nonpregnant females includes nitrofurantoin, fosfomycin tromethamine, or pivmecillinam 5.
- Second-line options for UTI treatment include oral cephalosporins, such as cephalexin or cefixime, fluoroquinolones, and β-lactams, such as amoxicillin-clavulanate 5.
- The choice of antibiotic should be guided by knowledge of common uropathogens and local susceptibility patterns to ensure effective treatment and minimize the risk of resistance development 5.
