RT Journal Article SR Electronic T1 Loperamide dependence and abuse JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr2015209705 DO 10.1136/bcr-2015-209705 VO 2015 A1 MacDonald, Ryan A1 Heiner, Jason A1 Villarreal, Joshua A1 Strote, Jared YR 2015 UL http://casereports.bmj.com/content/2015/bcr-2015-209705.abstract AB Loperamide is a common over-the-counter antidiarrheal considered safe in a broad range of dosages and thought devoid of abuse potential. We describe the first case of a patient with loperamide dependence due to misuse of its opiate-like effects achieved by chronic massive oral ingestions. A 26-year-old man who was taking 800 mg of loperamide per day presented requesting detoxification referral. Loperamide has potential for euphoric effects and information on how to facilitate such effects is easily available. It is important for physicians to be aware of the potential for misuse of and dependence on loperamide, with symptoms mimicking opiate use.
