From the Research

You should consult with your healthcare provider before taking Imodium (loperamide) with mesalamine and colestipol, as combining these medications requires professional guidance. While these medications can potentially be taken together, they each work differently in treating gastrointestinal conditions. Imodium slows intestinal movement to reduce diarrhea, mesalamine reduces inflammation in the colon, and colestipol binds bile acids to treat diarrhea and lower cholesterol. Some key points to consider when taking these medications together include:

  • Timing may be important, particularly with colestipol, which can bind to other medications and reduce their effectiveness if taken simultaneously 1, 2.
  • Take colestipol at least 1 hour before or 4-6 hours after other medications.
  • Potential side effects from this combination could include constipation, especially since both Imodium and colestipol can slow bowel movements.
  • Mesalamine has been associated with diarrhea as a side effect in some patients 2, which could be exacerbated by the use of Imodium.
  • There is also a potential for drug-drug interactions between mesalamine and other medications, such as tricyclic antidepressants, through CYP2D6 metabolism 3.
  • Additionally, mesalamine has been associated with severe symptomatic sinus bradycardia in some patients 4. Your doctor needs to evaluate your specific condition, medication dosages, and treatment goals to ensure this combination is appropriate and safe for your situation, as once-daily dosing of delayed-release oral mesalamine has been shown to be as effective as twice-daily dosing for maintenance of remission of ulcerative colitis 5.
