Abstract:
: Loperamide hydrochloride is an over-the-counter anti-diarrheal agent, acting via mu-opioid receptor agonist effects in the intestinal myenteric plexus. Although preclinical investigations suggested that abuse liability associated with loperamide use is low, there are increasing numbers of cases reported to the US Food and Drug Administration, of abuse, dependence, and withdrawal associated with loperamide use. A case of a patient with opioid use disorder, that is, in the form of protracted loperamide excess use, requiring management of withdrawal with methadone is presented. Management of withdrawal from abrupt loperamide discontinuation has not been discussed in the literature. Long-term treatment issues are also described.
