Bentyl (Dicyclomine Hydrochloride): Clinical Monograph for the Management of Irritable Bowel Syndrome and Functional Bowel Disorders

What Bentyl Actually Is and Why It Still Matters Look, I’ve been prescribing this compound for over twenty years now, and I still remember my first real encounter with it during residency. We had this gentleman, Mr. Caruso, 47, who came in doubled over with what we thought was an acute abdomen. Turned out to be severe IBS-D with a psychogenic overlay—his wife had just left him. The attending threw 20mg of Bentyl IM and within twenty minutes, the guy was sitting up, asking for coffee.
