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.

Ozempic Eye Side Effect NAION Warnings Update July 2026
Non-arteritic anterior ischemic optic neuropathy (NAION) is an eye side effect associated with Ozempic in numerous medical reports over the past couple of years. This article provides an Ozempic eye side effect NAION warnings update as of late July 2026 covering the US and some other countries around the world.
On July 23, 2026, the Australian drug regulatory agency Therapeutic Goods Administration (TGA) issued a Medicines Safety Update titled “GLP-1 RAs and rare vision disorder”, which pointed out that the Ozempic eye side NAION warnings would be added in Australia.

Further, in that July 2026 TGA Medicines Safety Update where the Ozempic NAION risk is highlighted, one finds a list of earlier actions taken by some other international drug regulators:
-
- United Kingdom: MHRA drug safety update: Semaglutide (Wegovy, Ozempic and Rybelsus): risk of Non-arteritic Anterior Ischemic Optic Neuropathy (NAION)
-
- European Union nations: EMA News: PRAC concludes eye condition NAION is a very rare side effect of semaglutide medicines Ozempic, Rybelsus and Wegovy
-
- World Health Organization member countries: WHO News: The use of semaglutide medicines and risk of non-arteritic anterior ischemic optic neuropathy (NAION)
However, the current (Revised: 5/2026 version) Ozempic Prescribing Information, or drug label, in the United States still does not include warnings about Ozempic-related eye side effects, such as NAION.
Drug injury lawsuits involving Ozempic for patients with vision loss due to NAION are being filed in the US against Novo Nordisk for its failure to include Ozempic eye side effect NAION warnings.
We emphasize that because there are no warnings in the current Ozempic drug label about an increased risk of NAION, those Ozempic lawsuits are not being filed against the doctors who prescribed Ozempic to the people who have suffered vision loss due to this serious eye-related side effect.
People diagnosed with NAION can submit an Ozempic Vision Loss Case Evaluation Form online. Or, if you prefer, call 910-256-2971 to talk with drug injury lawyer Tom Lamb about a possible Ozempic NAION lawsuit.
