Learn About Ozempic Vision Loss Side Effects

Over the past few years, drugs like Ozempic and Wegovy have exploded in popularity. Marketed for blood sugar control and dramatic weight loss, respectively, these medications have been prescribed to millions of people across the United States. Alarming research has linked Wegovy and Ozempic to vision loss side effects and blindness.

Reports suggest that some patients who took either Ozempic or Wegovy have experienced sudden vision problems.

  • Partial vision loss
  • Blindness

Lawsuits are being filed by individuals who claim they were not adequately warned about these potential risks.

If you or a loved one experienced vision loss after using Ozempic or Wegovy, you may qualify to file an Ozempic Lawsuit. The Yost Legal Group is actively investigating these cases and assisting patients in pursuing claims against the drug manufacturers.

Ozempic and Wegovy Linked to “Non-Arteritic Anterior Ischemic Optic Neuropathy” (NAION)

What are Ozempic and Wegovy?

Both Ozempic and Wegovy contain the same active ingredient: semaglutide. Semaglutide belongs to a class of medications known as GLP-1 receptor agonists. GLP 1 drugs mimic a natural hormone in the body that helps regulate blood sugar and appetite.

Although they share the same ingredient, Ozempic and Wegovy are approved for different uses:

Ozempic is FDA‑approved for adults with type 2 diabetes. It is used to improve blood sugar control and reduce the risk of major cardiovascular events such as heart attack and stroke.

Wegovy is FDA‑approved for chronic weight management in adults and adolescents aged 12 and older with obesity, or in overweight adults who have at least one weight‑related condition. It is also approved to reduce the risk of cardiovascular death, heart attack, and stroke in certain adults.

Wegovy is not specifically approved to treat diabetes. Still, some healthcare providers prescribe it as an “off‑label” use for patients with type 2 diabetes who could benefit from its weight‑loss effects.

As prescriptions for these weight loss drugs have surged, so have reports of unexpected and serious side effects – including vision problems.

Vision loss linked to NAION can happen suddenly and without pain. People taking Ozempic or Wegovy should be alert for any changes in their eyesight,

Ozempic and Wegovy Linked to “Non-Arteritic Anterior Ischemic Optic Neuropathy” (NAION)

Recent medical research has raised concerns about a possible connection between semaglutide and a serious eye condition called non-arteritic anterior ischemic optic neuropathy (NAION).

NAION occurs when blood flow to the optic nerve is suddenly reduced, damaging the nerve and causing rapid loss of vision. This damage can be permanent.

A 2024 study published in JAMA Ophthalmology examined patients who were prescribed semaglutide. The study found an increased risk of NAION compared with patients taking other medications for diabetes or weight loss without semaglutide.

The authors reported that the use of semaglutide was associated with a higher incidence of this vision‑threatening condition (NAION) in certain groups of patients.

In addition, a 2025 safety review by European regulators concluded that NAION should be listed as a “very rare” side effect of semaglutide‑containing medicines, including Ozempic and Wegovy.

Regulators advised that patients who experience sudden vision loss or rapidly worsening eyesight while taking semaglutide should seek urgent medical attention.

Other reviews and safety databases have also noted increased reports of visual impairment and optic nerve problems in patients using semaglutide compared with some other medications in the same class.

Researchers are still studying exactly how semaglutide might contribute to NAION or other eye conditions.

The pattern of reports is serious enough that many patients and doctors are now asking whether they were adequately warned about these risks.

What NAION Symptoms Should Patients Watch For?

Vision loss linked to NAION can happen suddenly and without pain. People taking Ozempic or Wegovy should be alert for any changes in their eyesight, including the following:

–             Sudden blurring or dimming of vision in one or both eyes

–             A dark or empty area in the center of vision

–             Loss of vision on one side or in a specific field of view

–             Difficulty seeing in low light or upon waking up

–             Sudden changes in color vision

These symptoms may appear shortly after starting the medication, after a dose increase, or even months after starting. Because NAION damages the optic nerve, time is critical.

Anyone experiencing sudden vision changes should seek emergency medical care and tell the doctor about all medications they are taking, including Ozempic or Wegovy.

Why Are Ozempic Lawsuits Being Filed?

Patients filing lawsuits against the manufacturers of Ozempic and Wegovy allege the following:

–             The companies failed to adequately warn patients and doctors about the risk of serious eye injuries, including NAION, vision loss, and potential blindness.

–             Important safety information was not clearly communicated in the prescribing information, marketing materials, or patient education resources.

–           If patients and their healthcare providers had been adequately warned, they might have chosen different treatments, monitored vision more closely, or stopped the medication sooner.

–           Drug manufacturers have a legal duty to design reasonably safe products and to provide clear, complete warnings about known or reasonably foreseeable risks.

–          When a company fails to do so, and patients are harmed as a result, those patients may be entitled to compensation through a lawsuit.

People who have suffered vision loss after taking Ozempic or Wegovy may face:

–             Medical bills

–             Loss of independence

–             Inability to work

–             Emotional distress

–             Long‑term disability

A medication lawsuit can help hold the manufacturers accountable and provide financial support for ongoing care and future needs.

Do You Qualify to Join an Ozempic Vision Loss Lawsuit?

Learn if you qualify to pursue a claim against the manufacturers of Ozempic or Wegovy if:

–             You used Ozempic or Wegovy (semaglutide) as prescribed by your healthcare provider; and

–             You were later diagnosed with a serious eye condition, such as non-arteritic anterior ischemic optic neuropathy (NAION), optic neuropathy, or other unexplained vision loss; and

–             Your vision loss occurred after starting the medication, even if you also had diabetes, high blood pressure, or other risk factors.

Every case is unique. The timing of your symptoms, your medical history, and the specific drug you were prescribed all matter.

That is why it is essential to consult with an experienced law firm that understands both the medical and legal aspects involved.

The Legal Basis for the Wegovy & Ozempic NAION Lawsuits

Novo Nordisk (Novo) is currently embroiled in a highly publicized and significant legal battle regarding the adequacy of its warning labels for its medications, Ozempic and Wegovy.

Over 1,500 product liability lawsuits against Novo Nordisk allege that the company failed to sufficiently warn of the potentially dangerous risks associated with Ozempic and Wegovy—specifically, vision loss or blindness from Non-arteritic anterior ischemic optic neuropathy (NAION).

This litigation is likely to gain momentum over time. It could become one of the costliest litigations in the history of product liability and pharmaceutical litigation.

About Ozempic and Wegovy

Ozempic and Wegovy are incretin mimetic medications that contain the active ingredient semaglutide. Incretin mimetics stimulate the pancreas to increase the production of insulin by imitating the incretin hormone that is naturally produced in the human body, glucagon-like peptide-1 (GLP-1).

Thus, they are part of a class of drugs called GLP-1. The increase in insulin lowers glucose levels in patients with type 2 diabetes, effectively controlling their metabolic condition.

The use of incretin mimetics has also been found to suppress appetite by increasing feelings of satiety, resulting in weight loss among its users.

Ozempic and Wegovy are once-weekly injectable medications approved by the United States Food and Drug Administration (FDA) in December 2017 to lower blood glucose levels in adults with type 2 diabetes and to aid in weight loss, respectively.

A licensed medical clinician must prescribe them to ensure that the patient receives the correct therapeutic dose.

After receiving the proper dose, the medication can be self-administered. Along with a balanced diet and regular exercise, Ozempic and Wegovy are intended for long-term use.

Novo Failed to Warn Patients of Risk of Vision Loss and Blindness

A “failure to warn” product liability lawsuit is based on the premise that a manufacturer or other company in the chain of distribution knew that its product could be harmful to consumers and failed to provide timely or adequate warnings to the public of these potential risks, causing harm to consumers.

In a failure to warn lawsuit based on strict liability, Plaintiffs must allege the following:

  1. The manufacturer knew of the danger posed by the product
  2. The manufacturer had a duty to warn its consumers of this product-related danger
  3. The manufacturer failed to warn
  4. The manufacturer’s failure to warn caused the plaintiff’s injury

What is NAION?

Non-arteritic anterior ischemic optic neuropathy (NAION) is a rare condition of the eye that can cause irreversible vision loss or complete blindness due to injury to the optic nerve.

NAION is a medical condition where there is a sudden loss of blood flow to the optic nerve, which connects your eyes to your brain. This lack of blood flow can damage the optic nerve, resulting in sudden vision loss, typically in one eye.

NAION is not caused by inflammation or blocked arteries (that’s what “non-arteritic” means), but rather by poor circulation or other risk factors like high blood pressure, diabetes, or sleep apnea.

The vision loss from NAION often happens quickly and can be permanent. There is currently no proven treatment to restore vision once it has been lost due to this condition. That is why it is so vital for people to be aware of any possible risks, especially when taking medications that may increase the chance of developing NAION.

What are NAION Symptoms?

The main symptoms of NAION (Non-arteritic anterior ischemic optic neuropathy) usually include:

–      Sudden, painless vision loss in one eye—often noticed upon waking up

–      Blurry or dim vision, sometimes described as a shadow or dark area in the upper or lower part of the visual field

–      Colors may appear less bright or washed out

–      Some people notice trouble seeing out of the corner of their eye or a loss of side vision

NAION does not usually cause pain or redness in the eye. If you notice any sudden changes in your vision, it’s important to contact an eye doctor right away.

Failure to Warn Patients of NAION Risk.

Novo knew or should have known of the elevated risk of this condition for consumers of its product based on emerging scientific evidence indicating the connection.

Manufacturers have a corporate responsibility and legal duty to provide clear and comprehensive warnings about the risks associated with their products. Then, consumers can make an informed decision with their healthcare provider about whether a medication is best suited for their needs.

Novo failed to fulfill its duty to warn of this risk factor in a timely manner. Based on the failure to warn, the blindness lawsuits allege that the lack of adequate warnings created a lack of informed consent and ultimately caused harm to consumers.
