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 and Wegovy NAION Study 2026 Report: Two New Findings
A recent Ozempic and Wegovy NAION study made two new findings about people who used Ozempic or Wegovy and then were diagnosed with non-arteritic anterior ischemic optic neuropathy (NAION) as a drug side effect that caused vision loss. The first is that the Wegovy NAION rate is five times that of Ozempic. The second is that for users of Ozempic and Wegovy, NAION was diagnosed in men three times more than in women.
These findings from the Ozempic and Wegovy NAION study were presented in this March 2026 British Journal of Ophthalmology article, “Ischemic optic neuropathy with semaglutide: global observational analysis of sex- and formulation-specific risk“.

We have been following the vision side-effect drug safety issue that is the subject of this Ozempic and Wegovy NAION study report since July 2024. During that time, we have investigated possible drug injury lawsuits against Novo Nordisk for patients diagnosed with NAION and who suffered vision loss.
