Drug-induced colitis

Last edited: 4/15/2026

Overview

Drug-induced colitis refers to inflammation of the colon caused by medications, often presenting with symptoms like diarrhea, abdominal pain, and sometimes bloody stools. It can result from various drug classes including nonsteroidal anti-inflammatory drugs (NSAIDs), antibiotics, and others 1.

Diagnosis

  • Clinical Presentation: Diarrhea, abdominal pain, hematochezia 1.
  • Recommended Tests: Stool cultures, endoscopy with biopsy to rule out infectious causes and confirm colitis 1.
  • Differential Diagnosis: Important to exclude infectious colitis, inflammatory bowel disease, and ischemic colitis 1.

    • Management

  • Discontinue Triggering Agent: Immediate cessation of the suspected drug 1.
  • Supportive Care: Fluid resuscitation, electrolyte management 1.
  • Antidiarrheal Agents: Loperamide for symptomatic relief in non-bloody diarrhea 1.
  • Antibiotics: Reserved for specific cases, such as suspected Clostridioides difficile infection 1.

    • Special Populations

  • No Specific Guidance Provided: The abstracts do not cover special populations including pregnancy, pediatrics, elderly, or comorbidities 1.

    • Key Recommendations

  • Implement electronic prescribing systems to potentially reduce adverse drug events and improve patient safety, leading to cost savings and efficiency gains (Evidence: Moderate) 1.
  • Promptly discontinue the suspected drug upon diagnosis of drug-induced colitis (Evidence: Expert opinion) 1.
  • Utilize supportive care measures including fluid and electrolyte management for symptomatic relief (Evidence: Expert opinion) 1.
