Parker Waichman LLP Responds to FDA Decision Requiring Vision Loss Warnings for Ozempic, Wegovy, Mounjaro, Zepbound, and Other GLP-1 Drugs

Landmark FDA Action Requires New Warnings About NAION, a Serious Eye Condition That Can Cause Sudden and Permanent Vision Loss

PORT WASHINGTON, N.Y., Nov. 10, 2026 /PRNewswire/ -- Parker Waichman LLP, a national law firm representing individuals who have suffered serious injuries associated with prescription medications, today welcomed the U.S. Food and Drug Administration's decision requiring manufacturers of GLP-1 medications to add warnings concerning the potential increased risk of non-arteritic anterior ischemic optic neuropathy (NAION), a serious eye condition that can cause sudden and permanent vision loss.

The FDA's announcement applies to the entire class of GLP-1 receptor agonist medications, including Novo Nordisk's Ozempic, Wegovy, and Rybelsus, as well as Eli Lilly's Mounjaro and Zepbound. The agency is requiring manufacturers to include information concerning the potential increased risk of NAION in the Warnings and Precautions section of their prescribing information.

"This is an important development for millions of Americans who rely on these medications and deserve to be fully informed about their potential risks," said Jason S. Goldstein, Senior Litigation Counsel at Parker Waichman LLP and Co-Chair of the Plaintiffs' Executive Committee in the federal GLP-1 NAION multidistrict litigation. "The FDA has now determined that the scientific evidence warrants an express warning about a condition that can cause permanent vision loss. Patients and their physicians should have this information when making decisions about treatment."

The FDA's decision represents a significant regulatory development concerning the safety of GLP-1 medications, which have become widely prescribed for diabetes and weight management. Unlike earlier international regulatory actions that focused primarily on semaglutide, the active ingredient in Ozempic and Wegovy, the FDA's announcement extends to the broader GLP-1 drug class, including medications manufactured by both Novo Nordisk and Eli Lilly.

NAION occurs when blood flow to the optic nerve is disrupted, potentially causing sudden, painless vision loss, typically in one eye. The resulting visual impairment can be permanent. For individuals who develop NAION, the consequences can be devastating, affecting their ability to work, drive, read, and perform ordinary activities of daily living.

Significance for Ongoing Federal Litigation

Parker Waichman LLP is actively involved in the federal multidistrict litigation involving GLP-1 medications and NAION, In re Glucagon-Like Peptide-1 Receptor Agonists (GLP-1 RAs) Non-Arteritic Anterior Ischemic Optic Neuropathy Products Liability Litigation, MDL No. 3163, pending before U.S. District Judge Karen S. Marston in the Eastern District of Pennsylvania.

The litigation involves allegations that certain GLP-1 medications can cause NAION and that manufacturers failed to adequately warn patients and healthcare providers about the potential risk of sudden and permanent vision loss.

The FDA's decision is particularly significant because the agency has now determined that the potential risk of NAION warrants an explicit warning in the prescribing information for these medications. The decision comes as litigation proceeds over whether manufacturers should have warned patients and healthcare providers about this risk earlier.

"For individuals who have already suffered permanent vision loss, today's announcement is especially meaningful," Goldstein added. "The central issue in these cases has always been whether patients and physicians were adequately warned about the risk of NAION. The FDA's decision underscores the importance of those warnings and raises serious questions about when manufacturers had sufficient information to alert the public to this potentially devastating injury."

The FDA's labeling action does not itself resolve the claims pending in the litigation, and the manufacturers dispute the allegations.
