ADA Advises Against Using Compounded GLP-1 RA Medications

In a new statement, the American Diabetes Association (ADA) has advised against the use of compounded glucagon-like peptide 1 receptor agonist (GLP-1 RA) and dual glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 RA medication classes.

The ADA recommends GLP-1 RA and GIP/GLP-1 RA medications approved by the US Food and Drug Administration (FDA) for the treatment of type 2 diabetes, cardiovascular and kidney disease risk reduction, and weight management. The new ADA statement pertains to the unapproved, unregulated versions that have emerged as the demand for these medications for weight loss increases. These are often marketed directly to consumers.

“Compounded GLP-1 RA and dual GIP/GLP-1 RA products have been associated with clinically important dosing errors and adverse events. More concerning to individuals’ safety are counterfeit products that have made their way into the US drug supply chain and those advertised online and by unregulated sources,” the ADA said in the statement, published online on December 2, 2024, in Diabetes Care.

The statement, authored by Joshua J. Neumiller, PharmD, CDCES, of the Department of Pharmacotherapy, Washington State University, Spokane, Washington, and colleagues, states the following:

• Non-FDA–approved compounded incretin products are not recommended for use due to uncertainty about their content and resulting concerns about safety, quality, and effectiveness.
• If an incretin medication is unavailable (eg, in shortage), switching to a different FDA-approved medication is recommended as clinically appropriate to achieve and maintain individualized glucose-lowering, weight management, and/or cardiovascular and kidney risk reduction goals.
• Upon resolution of incretin product unavailability, reassess the appropriateness of resuming the original FDA-approved incretin medication.

The document points out that compounded products are not identical to the FDA-approved versions, may be distributed in nonstandard dosing devices, and may not provide sufficient user instructions.

However, “the ADA also recognizes that individuals and clinicians may still elect to use or recommend compounded products for financial or other reasons,” and therefore offers additional advice for the public, including the following:

• Discuss product use with their usual healthcare providers.
• Only use products that include dosing guidance.
• Verify that the compounding pharmacy is registered with FDA.
• Report any adverse events or medication errors to the FDA’s Medwatch.
