Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Dicyclomine (Bentyl) and Librax (chlordiazepoxide/clidinium) are both used to treat irritable bowel syndrome (IBS), but they work differently and belong to different medication classes. Dicyclomine is an anticholinergic that helps by relaxing the muscles in your stomach and intestines, and it is available in generic form. You typically take it four times a day. Common side effects include dizziness, dry mouth, and blurry vision. On the other hand, Librax combines a benzodiazepine (chlordiazepoxide) and an anticholinergic (clidinium) to address both the emotional and physical aspects of stomach conditions. It is also available in generic form and is usually taken three to four times a day. Librax can cause drowsiness, confusion, and has a risk of dependence and withdrawal if used long-term. While both medications can cause dry mouth and blurry vision, Librax has additional risks related to its benzodiazepine component, such as potential misuse and addiction.
