FDA Seeks Patient Input on Loperamide Restrictions

Share

FDA commissioner Scott Gottlieb says the agency is seeking input from the patient community on how best to strike a balance between restricting loperamide availability to deter its abuse to produce an opioid high and the legitimate need for the drug for patients suffering from chronic diarrhea associated with inflammatory bowel disease, including Crohn’s disease. Loperamide is sold in branded and generic prescription forms and over-the-counter as Immodium A-D.

Writing in an FDA Voice blog post, Gottlieb says FDA doesn’t want to create access issues for patients with chronic diarrhea, and is proceeding in a step-wise, deliberative fashion “to ensure that the actions we take in relation to OTC loperamide use are reasonable and scientifically sound, and that these actions are necessary to achieve safe use of the drug and to address the issue of abuse and misuse.”

One of the steps FDA has announced is to ask manufacturers to change packaging of the OTC product, such as using blister packs, to help deter abuse. “OTC loperamide is currently approved in packages of eight to 200 tablets, which are often sold in multipacks of more than 1,000 tablets at a time,” Gottlieb says. “This is more than a three-year supply if the drug is taken according to the product label. Evidence suggests that reasonable packaging limitations and unit-of-dose packaging may reduce medication overdose and death.”
