Cipro and Diarrhea
Although most people do not have any problems while taking Cipro® (ciprofloxacin), this antibiotic is not free of dangerous risks. In clinical studies, one of the most common side effects of Cipro was diarrhea, occurring in up to 1.6 percent of people taking this drug. In most cases, this side effect tends to be minor and easily treated.
However, antibiotics like Cipro can disrupt the normal bacteria in the digestive tract, allowing undesirable bacteria to overgrow. This can potentially lead to a serious problem known as pseudomembranous colitis. This severe reaction can occur months after you stop taking Cipro and can lead to life-threatening complications. Make sure to let your healthcare provider know right away if you experience bloody or watery diarrhea.
