From the Guidelines
Treatment for Irritable Bowel Syndrome with Diarrhea (IBS-D) should prioritize a multifaceted approach including dietary modifications, soluble fiber supplements, and pharmacological interventions such as loperamide, with consideration of rifaximin for recurrent symptoms and stress management techniques. The management of IBS-D involves a combination of non-pharmacological and pharmacological strategies.
Non-Pharmacological Approaches
- Dietary modifications are first-line treatments, including following a low-FODMAP diet that restricts fermentable carbohydrates for 4-6 weeks, followed by systematic reintroduction to identify triggers 1.
- Soluble fiber supplements like ispaghula (starting at 3-4g daily and gradually increasing) can help regulate bowel movements and reduce symptoms 1.
- Regular exercise and stress management techniques such as cognitive behavioral therapy and gut-directed hypnotherapy are also crucial components of treatment, as they address the brain-gut connection that plays a central role in IBS pathophysiology 1.
Pharmacological Interventions
- Loperamide is recommended for the treatment of diarrhea in IBS-D, given its ability to slow intestinal transit and reduce symptoms 1.
- Antispasmodics may be considered for abdominal pain and cramping, although their use should be balanced with potential side effects 1.
- For patients with more severe symptoms, prescription medications like rifaximin, which targets potential bacterial overgrowth, can be considered, with the option for retreatment in cases of recurrent symptoms 1.
Key Considerations
- The choice of treatment should be individualized based on the patient's specific symptoms, medical history, and response to initial therapies.
- A step-wise approach, starting with dietary and lifestyle modifications and progressing to pharmacological interventions as needed, is often the most effective strategy for managing IBS-D symptoms and improving quality of life.

From the Research
Treatment Options for IBS-D
The treatment options for Irritable Bowel Syndrome with Diarrhea (IBS-D) include:
- Dietary and lifestyle modifications, such as adequate hydration, reducing caffeine and alcohol intake, and increasing soluble fiber intake 4
- Over-the-counter medications, including loperamide, which may improve stool frequency and rectal urgency 4, 5
- Prescription medications, such as:
- Rifaximin, a nonabsorbable antibiotic, which has been shown to provide mild to moderate efficacy in managing IBS-D 6, 7, 5
- Eluxadoline, a gut-targeting μ and κ opioid receptor agonist and a δ opioid receptor antagonist, which has been shown to provide relief to patients with IBS-D 6, 4, 7, 5
- Alosetron, a 5-HT3 receptor antagonist, which is approved for the treatment of IBS-D 4, 8, 7
- Alternative treatments, including probiotics, acupuncture, and exercise, which may be useful adjuncts to other therapies 8
- Psychotherapy, which has been shown to be effective in the treatment of IBS 8
Pharmacological Treatment
Pharmacological treatment options for IBS-D include:
- Antidiarrheal medications, such as loperamide 4, 5
