The use of metronidazole (Flagyl) in Crohn's disease
1Gastroenterology Division, Palo Alto Medical Clinic, California 94301.
Abstract:
The efficacy of metronidazole in the treatment of Crohn's disease remains unproven. It has not been superior to a placebo in three small studies. Uncontrolled reports suggest it may be of benefit in selected patients who have not responded to previous medical or surgical therapy. Metronidazole therapy can lead to complete healing of perineal fistulas. Persistent concerns over side-effects, carcinogenicity, and bacterial resistance suggest that drug should be prescribed with caution for long-term use.
Insights
Metronidazole
Area of Science:
- Gastroenterology and Inflammatory Bowel Disease Research
Background:
- Crohn's disease is a chronic inflammatory bowel condition.
- Treatment options for Crohn's disease are continuously being evaluated.
Purpose of the Study:
- To evaluate the efficacy of metronidazole in treating Crohn's disease.
- To assess metronidazole's effectiveness in specific patient subgroups and for particular complications.
Main Methods:
- Review of existing clinical studies and uncontrolled reports on metronidazole use in Crohn's disease.
- Analysis of treatment outcomes, including comparisons with placebo and assessment of effects on perineal fistulas.
Main Results:
- Three small studies found metronidazole not superior to placebo for general Crohn's disease treatment.
- Uncontrolled data suggest potential benefits in select patients refractory to other therapies.
- Metronidazole demonstrated efficacy in achieving complete healing of perineal fistulas.
Conclusions:
- The overall efficacy of metronidazole for Crohn's disease is not definitively proven.
- While potentially beneficial for perineal fistulas and refractory cases, caution is advised due to side effects, carcinogenicity concerns, and bacterial resistance.
- Long-term metronidazole use in Crohn's disease requires careful consideration of risks and benefits.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
