From the Guidelines
Diarrhea associated with Revlimid (lenalidomide) should be managed with loperamide as the first-line treatment, starting at 4mg initially, followed by 2mg after each loose stool, not exceeding 16mg daily, as recommended by the most recent guidelines 1.
Management of Diarrhea
The management of diarrhea associated with Revlimid involves a combination of dietary modifications, hydration, and medications. Patients should maintain adequate hydration by drinking 8-10 glasses of water daily and follow a BRAT diet (bananas, rice, applesauce, toast) while avoiding spicy foods, dairy products, and high-fiber foods during episodes.
Medications
- Loperamide (Imodium) is the recommended first-line treatment, with a starting dose of 4mg, followed by 2mg after each loose stool, not exceeding 16mg daily 1.
- For persistent diarrhea, prescription medications such as diphenoxylate/atropine (Lomotil) at 2.5-5mg four times daily or octreotide 100-150mcg subcutaneously three times daily may be needed 1.
- Severe cases might require Revlimid dose reduction or temporary discontinuation.
Monitoring and Follow-up
Patients should contact their healthcare provider if diarrhea persists beyond 24 hours, contains blood, is accompanied by fever above 100.4°F, or causes signs of dehydration. Diarrhea occurs because lenalidomide affects the intestinal mucosa and alters gut flora, disrupting normal water absorption in the intestines. Prompt management is essential as severe diarrhea can lead to dehydration, electrolyte imbalances, and may necessitate treatment interruptions that could compromise cancer therapy outcomes.
Key Considerations
- The most recent guidelines recommend loperamide as the first-line treatment for diarrhea associated with Revlimid 1.
- Patients with severe diarrhea may require hospitalization and aggressive management with intravenous fluids and antibiotics 1.
- Probiotics, such as Lactobacillus, Bifidobacterium, and cocci, may be considered as a preventive measure, but further safety analysis is needed in immunocompromised patients 1.

From the Research
Management of Diarrhea Associated with Revlimid (Lenalidomide)
- Diarrhea is a common side effect of lenalidomide (Revlimid), particularly in patients with multiple myeloma, and can be severe enough to require dose reduction or discontinuation of treatment 2.
- Late-onset diarrhea from lenalidomide can occur 17-24 months after the start of therapy, and treatment is often by dose reduction and discontinuation of the offending drug 2.
- However, best practices for diarrhea management in multiple myeloma are poorly understood, and diarrhea symptoms can impede patient adherence and undermine quality of life 2.
Treatment Options for Diarrhea
- Octreotide has been shown to be effective in controlling diarrhea caused by various chemotherapy agents, including fluorouracil, irinotecan, and lenalidomide 3, 4.
- In a randomized trial, octreotide was found to be more effective than loperamide in controlling diarrhea and eliminating the need for replenishment of fluids and electrolytes 3.
- Octreotide has also been used to treat refractory diarrhea following bone marrow transplantation, with complete responses observed in patients with regimen-related toxicity 5.
Specific Treatment Regimens
- A dosage of 0.1 mg of octreotide subcutaneously twice per day for 3 days has been shown to be effective in controlling diarrhea 3.
- In patients with irinotecan-induced diarrhea, octreotide has been administered at a dosage of 50 μg subcutaneously every 8 hours, with a high response rate (92%) 4.
- In a case report, octreotide 50 μg subcutaneously every 8 hours was used to treat a patient with cytomegalovirus colitis-associated diarrhea that was unresponsive to loperamide, with significant improvement in symptoms 6.
