Don’t Move Imodium from OTC to Rx: CHPA

Share

The Consumer Healthcare Products Association (CHPA) says FDA should deny a citizen petition filed by a Sajoy Varghese of the Jesse Brown VA Medical Center, Chicago, seeking an amendment of the marketing status of Imodium (loperamide) from nonprescription (over-the-counter) to prescription. “Based on the available evidence demonstrating a long history of safe and effective use of loperamide when used according to labeled directions as well as a low rate of abuse/misuse of loperamide, we do not believe that changing the marketing status of loperamide from OTC to prescription is warranted,” a CHPA petition response says. “While published literature reports of serious cardiac adverse events and deaths in association with massive overdose of loperamide have increased in recent years, the number of such events is still extremely low.”

The association says it is working with its member companies and FDA to further assess reports of loperamide misuse/abuse and to develop additional strategies to mitigate such occurrences. Its letter notes a 6/2016 FDA drug safety communication addressing serious heart problems reported in association with loperamide taken in doses higher than recommended, often to avoid opiate withdrawal or as an opiate substitute. “The majority of these cases involved individuals who were intentionally misusing/abusing high doses of loperamide,” it says. CHPA says that issues raised by the agency in its safety communication were addressed in an 8/2016 product labeling update when FDA issued a supplement request to update labeling for loperamide NDA products. The changes included addition of a Heart Alert warning and revised pediatric dosing instructions, it says.

The association says it and its member companies are considering a broad range of actions intended to develop a better understanding of the misuse and/or abuse of loperamide, including monitoring and assessing cases of loperamide abuse reported in social media or reported to databases. “Such efforts may contribute to the understanding of trends and aid the development of effective interventions,” the letter says. “We are also discussing ways to effectively communicate with a broad range of stakeholders in this effort as a means of enhancing understanding and awareness of this issue. Through cooperative efforts such as these, and ongoing monitoring, CHPA believes that loperamide can safely remain an over-the-counter product.”
