Key takeaways
Dicyclomine (Bentyl) and loperamide (Imodium A-D) are both medications used to treat gastrointestinal issues, but they belong to different drug classes and have different uses. Dicyclomine is an anticholinergic medication primarily used to treat irritable bowel syndrome (IBS) by relaxing the muscles in the stomach and intestines to reduce cramping. Loperamide, on the other hand, is an antidiarrheal medication used to control symptoms of diarrhea, including those related to chronic gut conditions. While dicyclomine is available only by prescription, loperamide can be purchased over-the-counter or by prescription. Dicyclomine is typically taken four times a day, whereas loperamide is taken after each loose stool, with specific dosing limits. Common side effects of dicyclomine include dizziness, dry mouth, and blurred vision, while loperamide may cause dizziness, drowsiness, and constipation. Additionally, dicyclomine can interact with anticholinergic medications, while loperamide should be used cautiously with medications affecting heart rhythm.
