From the Guidelines

Azithromycin is the recommended treatment for Campylobacter infections, particularly for severe cases, immunocompromised patients, pregnant women, or those with high fever, bloody diarrhea, or symptoms lasting longer than a week, due to its efficacy and lower resistance rates compared to fluoroquinolones like ciprofloxacin 1. The treatment of Campylobacter infections should be guided by the severity of symptoms and the patient's overall health status.

  • For uncomplicated cases in otherwise healthy individuals, supportive care, including rest and adequate fluid intake, is usually sufficient.
  • Antibiotic therapy may be warranted for severe infections, immunocompromised patients, pregnant women, or those with high fever, bloody diarrhea, or symptoms lasting longer than a week.
  • The preferred antibiotic is azithromycin (500 mg once daily for 3 days) due to its efficacy and lower resistance rates compared to fluoroquinolones like ciprofloxacin 1.
  • Ciprofloxacin (500 mg twice daily for 3-5 days) is an alternative option, though increasing resistance to fluoroquinolones has been reported 1.
  • Antimotility agents like loperamide should be avoided in cases of bloody diarrhea as they may prolong bacterial exposure in the intestines.
  • Patients should maintain good hygiene practices during infection to prevent transmission to others, including thorough handwashing after using the bathroom and before handling food. The rationale for limited antibiotic use is to avoid unnecessary treatment that might contribute to antibiotic resistance while recognizing that targeted therapy can reduce symptom duration and bacterial shedding in appropriate cases 1.

From the FDA Drug Label

Infectious Diarrhea caused by Escherichia coli (enterotoxigenic strains), Campylobacter jejuni, Shigella boydii†, Shigella dysenteriae, Shigella flexneri or Shigella sonnei† when antibacterial therapy is indicated.

The recommended treatment for Campylobacter infections is ciprofloxacin (PO), as it is indicated for the treatment of infectious diarrhea caused by Campylobacter jejuni 2.

From the Research

Campylobacter Treatment

The recommended treatment for Campylobacter infections is typically focused on managing symptoms and, in some cases, using antibiotics to shorten the duration of the illness.

  • Azithromycin has been shown to be effective in treating Campylobacter infections, particularly in areas where ciprofloxacin resistance is prevalent 3.
  • A study comparing azithromycin to placebo for the treatment of Campylobacter concisus diarrhea in adults found no significant difference in clinical outcomes between the two groups, although the study was limited by a small sample size 4.
  • Antibiotic susceptibility profiles among Campylobacter isolates have shown high rates of resistance to ciprofloxacin, with varying rates of resistance to other antibiotics such as erythromycin and tetracycline 5.

Antibiotic Resistance

  • Campylobacter species have developed significant resistance to various antibiotics, making treatment challenging 5, 6.
  • Amoxicillin-clavulanic acid has been proposed as a potential treatment for campylobacteriosis due to its high susceptibility rates 6.
  • The use of antibiotics such as azithromycin and ciprofloxacin should be guided by antibiotic susceptibility testing to ensure effective treatment and minimize the development of resistance 3, 5, 6.

Treatment Considerations

  • The choice of antibiotic treatment for Campylobacter infections should be based on the severity of symptoms, the presence of antibiotic resistance, and the specific species of Campylobacter involved 3, 7, 6.
  • In some cases, supportive care such as hydration and rest may be sufficient to manage mild symptoms, while antibiotic treatment may be necessary for more severe cases or in individuals with underlying health conditions 7.
