Drugs With Semaglutide Linked to Nonarteritic Anterior Ischemic Optic Neuropathy (NAION)
In a rush? You can use our Quick Contact Form to tell us the basic information about your case.
Two large medical studies from Denmark presented in December 2024 provide more evidence of a link between Ozempic and an eye condition called NAION (non-arteritic anterior ischemic optic neuropathy), finding that people who used Ozempic have more than a two-times increased risk of developing this serious eye side effect, which can cause vision loss and blindness.
These two Danish medical studies serve to confirm what was first reported in a July 2024 medical journal article, that Wegovy, Rybelsus, and Ozempic are linked to eye problems because semaglutide, which is the active ingredient for each of these three drugs, is associated with NAION.
Eye-related side effects of Ozempic, Wegovy, and Rybelsus with possible vision loss is a drug safety issue for these semaglutide-containing medications from Novo Nordisk that is generally unknown to many.
Here is what you need to know:
- Ozempic, Wegovy, and Rybelsus are drugs with semaglutide as their active ingredient.
- Semaglutide has been linked to nonarteritic anterior ischemic optic neuropathy (NAION).
- NAION is sometimes referred to as an “eye stroke,” and it occurs when there is a lack of sufficient blood flow to the optic nerve.
- NAION typically causes sudden vision loss and, in severe cases, can lead to blindness.
- There are currently no proven treatments for NAION.
The current drug labels for Ozempic, Wegovy, and Rybelsus do not warn about eye-related side effects, such as possible vision loss.
We are looking into possible drug injury lawsuits for patients who developed eye-related side effects of Ozempic, Wegovy, and Rybelsus from Novo Nordisk.
Drug injury lawsuits involving Ozempic, Wegovy, and Rybelsus for patients with vision loss due to nonarteritic anterior ischemic optic neuropathy (NAION) would be filed against Novo Nordisk for its failure to warn about any eye problems such as vision loss.
And because there are no warnings in the current drug labels about an increased risk of eye-related side effects for Ozempic, Wegovy, and Rybelsus, those drug injury cases would not be filed against patients’ doctors.

Mounjaro and Ozempic NAION Vision Loss Lawsuits: Federal Court MDL No. 3163
As seen elsewhere on this Drug Injury Law website, we have been investigating Mounjaro and Ozempic NAION vision loss lawsuits seeking legal compensation for the person suffering from this serious eye side effect injury:
- Zepbound and Mounjaro Eye Side Effect NAION Information Page
- Eye-related Side Effects of Ozempic, Wegovy, and Rybelsus With Vision Loss
As indicated on those two webpages, Mounjaro NAION vision loss lawsuits would be filed against Eli Lilly, and Ozempic NAION vision loss lawsuits would be filed against Novo Nordisk.

Because there are no warnings about NAION vision loss for Ozempic or Mounjaro in their current drug labels, those drug injury cases would only be filed against these responsible pharmaceutical companies — and not against patients’ doctors.
As regards the Mounjaro and Ozempic NAION vision loss lawsuits that are filed in federal courts, the U.S. Judicial Panel on Multidistrict Litigation (JPML) issued a December 2025 ruling that keeps these NAION lawsuits separate and apart from hundreds of earlier-filed Mounjaro and Ozempic cases involving gastrointestinal side effects.
The new federal court MDL case for the consolidation of Mounjaro and Ozempic NAION vision loss lawsuits is IN RE: Glucagon-like Peptide-1 Receptor Agonists (GLP-1 RAs) Non-Arteritic Anterior Ischemic Optic Neuropathy [NAION] Products Liability Litigation, MDL No. 3163.
In addition to Mounjaro and Ozempic, this relatively new MDL No. 3163 lawsuits “consolidation” — which is not the same as a “class action”, but often confused with such — includes NAION cases involving a few other injectable GLP-1 agonist medicines from Eli Lilly (Zepbound) and Novo Nordisk (Wegovy and Rybelsus).
For these NAION vision loss lawsuits, we offer an online case evaluation service that is free and confidential, and without obligation:
