Ozempic (GLP-1) Lawsuit — Free Case Review

Sudden Vision Loss Deserves Answers

If NAION was diagnosed during or after brand-name GLP-1 use and some vision loss is permanent, you may qualify — spouses and family welcome to call.

No Ozempic or other GLP-1 lawsuit has been settled, and no court or jury has found that these medications caused anyone's injury — the litigation is ongoing, with major expert-evidence rulings still ahead. Whether any individual has a claim depends on their own medical records and the law of their state.

Sudden, painless vision loss in one eye — noticed on waking, often as a gray curtain across the lower half of the visual field — is the way NAION usually begins. NAION is an injury to the optic nerve caused by interrupted blood flow. Anyone experiencing sudden vision loss needs to be seen by a doctor urgently, because several causes are medical emergencies. Once a NAION diagnosis is made, and where a GLP-1 medication was being taken, there is now a federal litigation: MDL 3163, with 247 cases pending as of October 2026.

If this is happening right now, stop reading and get medical care. Sudden vision loss can have several causes, and some of them — including giant cell arteritis — need treatment within hours to protect the other eye. A law firm is not the first call. An emergency room or an eye specialist is.

Reports submitted to FDA are not verified and do not establish causation; they are voluntary, can duplicate one another, and rise and fall with prescribing volume and news coverage.

How people describe it

The descriptions are remarkably consistent, and if any of them sound like your morning, that is worth knowing:

• Noticing it on waking — sudden, overnight, with no warning the day before.
• A gray shadow or curtain across the top or the bottom of the field of vision.
• Central vision still working while the lower half is missing — some people describe the remaining field as shaped like a C.
• Faint images fading in and out; colors looking washed out or flat.
• Worse on waking, then settling somewhat as the day goes on.
• The eye itself feeling puffy, heavy, or tired — but no pain.
• Realizing only by chance — covering one eye, taking out a contact lens — that the other eye had been doing all the work.

The absence of pain is a big part of why people wait. It does not feel like an emergency. It is one.

What causes this pattern

The optic nerve carries visual signal from the eye to the brain. When blood flow to the front of that nerve is interrupted, the tissue is injured, and the part of the visual field it served goes with it. That is NAION — non-arteritic anterior ischemic optic neuropathy. “Non-arteritic” distinguishes it from giant cell arteritis, an inflammatory condition that damages the nerve a different way and requires immediate treatment. Ruling that out is one of the first things a specialist does.

Most people are told there is no known cause. Contributing factors named are usually circulation and the shape of the optic disc — a small, crowded disc sometimes called a “disc at risk.” The typical age at onset is around 66. There is no treatment shown to reverse it once it has happened, which is a hard thing to be told on the same day you are told what it is.

Why a medication comes into it

Since 2024, semaglutide — the medicine in Ozempic, Wegovy and Rybelsus — has been studied as a possible contributing factor.

In June 2025 the European Medicines Agency’s safety committee concluded that NAION is a “very rare” side effect of these medicines, meaning it may affect up to 1 in 10,000 people, and required NAION to be added to the European product information. The committee described roughly a two-fold increase in risk and about one additional case per 10,000 person-years. Regulators in the UK and Australia have since taken similar steps. As of September 23, 2026, verified against the FDA-posted prescribing information (Ozempic PI, NDA 209637 s038, revision 05/2026), the US label still carries no NAION warning.

That is the honest shape of it: a real, replicated association with a small absolute risk, acted on by several regulators abroad and not yet reflected in what American patients are told. The full science and litigation picture is here.

If you are the one doing the reading

Often the person searching is not the person it happened to. If you are a spouse or an adult child piecing this together — noticing that nothing else in their life changed except this medication, and wondering whether that means anything — that instinct is why several of these cases exist. You are allowed to look into it, and you do not need to have it figured out before you call.

Who may qualify today

• Use of brand-name Ozempic, Wegovy, Rybelsus, Trulicity, Mounjaro, or Zepbound — not compounded or generic versions.
• An actual NAION diagnosis from a physician. Symptoms alone, without a diagnosis, are not enough — and if you have symptoms and no diagnosis yet, the next step is a doctor, not a lawyer.
• Diagnosed while taking the medication or after stopping it.
• Some degree of permanent vision impairment.
• Not already represented by another lawyer for this issue.
• No age limit, no hospital requirement, and no diagnosis-date cutoff applies to this track.

You are not suing the doctors

This is a claim against the companies that made and labeled the medication — Novo Nordisk and Eli Lilly. It is not a claim against the prescriber, the optometrist who caught it, or the ophthalmologist who made the diagnosis. Those records are usually what a claim rests on.
