Ciprofloxacin for Traveler's Diarrhea

Treatment Recommendations

For moderate to severe traveler's diarrhea, ciprofloxacin 500 mg twice daily for 3-7 days is an appropriate treatment regimen, as recommended by the Centers for Disease Control and Prevention 2, 3
Ciprofloxacin should not be administered to children or pregnant women; alternative antibiotics such as trimethoprim-sulfamethoxazole (TMP-SMZ) should be considered for these populations, according to the Centers for Disease Control and Prevention and the American College of Obstetricians and Gynecologists 2, 4

Fluoroquinolone resistance exceeds 85% for Campylobacter in Southeast Asia, making azithromycin clearly superior in this region, as noted by the World Health Organization 1
Increasing fluoroquinolone resistance is being reported globally, not just in Southeast Asia, which may limit ciprofloxacin's effectiveness in certain regions, according to the World Health Organization 1

Routine antimicrobial prophylaxis with ciprofloxacin is not recommended due to potential adverse effects, risk of promoting drug-resistant organisms, and association with acquisition of multidrug-resistant bacteria, as stated by the Centers for Disease Control and Prevention and the Infectious Diseases Society of America 1, 2, 4
Seek medical attention if diarrhea is severe and does not respond to empirical therapy, stools contain blood, fever is accompanied by shaking chills, or dehydration develops, as advised by the Centers for Disease Control and Prevention 2, 3

Food and water precautions remain the cornerstone of prevention, and safe items include steaming hot foods, peeled fruits, bottled beverages, hot coffee/tea, beer, wine, and water boiled for >1 minute, as recommended by the Centers for Disease Control and Prevention and the World Health Organization 2, 4
