From the Guidelines
Treatment for IBS with diarrhea should prioritize medications that address both the gastrointestinal symptoms and the potential psychological comorbidities, with a strong recommendation for tricyclic antidepressants like amitriptyline for global symptoms and abdominal pain, as supported by the British Society of Gastroenterology guidelines 1. When considering treatment options for IBS with diarrhea (IBS-D), it's essential to address both the physical symptoms and the psychological aspects that often accompany the condition.
- Lifestyle modifications are crucial and include dietary changes such as following a low-FODMAP diet, identifying and avoiding trigger foods, managing stress through techniques like meditation or cognitive behavioral therapy, and regular exercise.
- Medications play a significant role in managing symptoms. Loperamide can be used to slow intestinal transit and reduce diarrhea, while antispasmodics like dicyclomine or hyoscyamine can relieve abdominal cramping.
- For more severe cases, prescription medications such as eluxadoline, which reduces intestinal contractions, or bile acid sequestrants like cholestyramine for suspected bile acid malabsorption, can be considered.
- The use of tricyclic antidepressants like amitriptyline is supported by guidelines for their effectiveness in treating global symptoms and abdominal pain in IBS, as noted in the British Society of Gastroenterology guidelines 1.
- Psychological therapies, including IBS-specific cognitive behavioral therapy and gut-directed hypnotherapy, may also be efficacious for global symptoms in IBS, especially when symptoms persist despite drug treatment, as recommended in the guidelines 1.
- It's also important to consider the role of probiotics, though the specific strains and dosages that are beneficial can vary, and their use should be individualized based on patient response. The approach to treating IBS-D should be multidisciplinary, incorporating both medical and psychological interventions to address the complex interplay between gastrointestinal symptoms and mental health comorbidities, as outlined in the Nature Reviews Gastroenterology and Hepatology publication 1.

From the Research
Treatment Options for IBS Diarrhea
The treatment options for Irritable Bowel Syndrome (IBS) with diarrhea include both nonpharmacological and pharmacological interventions 4.
- Nonpharmacological interventions:
- Dietary and lifestyle modifications, such as adequate hydration, reducing caffeine and alcohol intake, and increasing soluble fiber intake 5
- Psychological therapies, including cognitive behavioral therapy and hypnotherapy 4
- Probiotics, which have demonstrated efficacy and safety in patients with IBS, although studies are inconsistent in strains examined, dosing, and treatment duration 4
- Pharmacological interventions:
- US Food and Drug Administration-approved agents: eluxadoline, rifaximin, and alosetron 4, 6, 5
- Loperamide, which can improve stool frequency and rectal urgency, but has mixed results for abdominal pain 5, 7
- Smooth muscle antispasmodics, bile acid sequestrants, and antidepressants, which can be used off-label for IBS-D management 4, 5, 7
FDA-Approved Medications
The FDA-approved medications for IBS-D include:
- Eluxadoline, which has been shown to improve abdominal pain and stool consistency in patients with IBS-D 4, 5, 8
- Rifaximin, which has been shown to improve abdominal pain and stool consistency in patients with IBS-D, and has a favorable safety profile 4, 6
- Alosetron, which improves IBS symptoms, but is approved only for women with severe IBS-D 4, 6, 5
Considerations for Treatment
When formulating a management plan for patients with IBS-D, it is essential to consider the most troublesome symptoms, quality of life, symptom intensity, and individual patient preferences 4. The risk-benefit ratio of each medication should also be taken into account, particularly for functional GI disorders such as IBS-D 4.
