The effectiveness of single- or multiple-agent antibiotic regimens for outpatient therapy are essentially the same when they provide both anaerobic and aerobic coverage. [6, 7]

Potential regimens include the following:

  • Ciprofloxacin plus metronidazole

  • Trimethoprim-sulfamethoxazole plus metronidazole

  • Amoxicillin-clavulanate

  • Moxifloxacin (for patients intolerant of both metronidazole and beta-lactam agents)
