Loperamide Abuse and Dependence: Clinical Features and Treatment Considerations.

Abstract

: Opioid use disorder and its associated mortality have become national epidemic problems. Different measures and regulations have been implemented to curb this trend, including stricter opioid prescribing practice. With the decreased access to prescription opioids, individuals with opioid use disorder have explored alternatives including loperamide, a peripheral opioid mu-receptor agonist. There are reports of increased loperamide misuse, dependence, and mortality rate in the past few years from poison control centers, medical examiners' offices, and clinical settings. Here, we report a case of loperamide use disorder, which led to the death of the patient. Associated clinical features and treatment of loperamide use disorder, including management of intoxication and withdrawal, and long-term maintenance therapy are discussed along with potential prescribing and sale regulations to manage this newly emerging substance use disorder.
