The 2009 American College of Gastroenterologists (ACG) position statement on the management of irritable bowel syndrome noted that the antidiarrheal agent loperamide effectively reduced stool frequency and improved stool consistency, but it did not relieve pain, bloating, or other global irritable bowel syndrome symptoms. [3] As noted earlier, the 2014 ACG monograph on the management of irritable bowel syndrome and chronic idiopathic constipation found insufficient evidence to recommend prebiotics or synbiotics, or loperamide, in irritable bowel syndrome, and no evidence that polyethylene glycol improved overall symptoms and pain in affected patients. [32] The most recent 2018 ACG monograph on the management of IBS has upheld these aforementioned recommendations. [51]
