How semaglutide-related NAION can cause harm

NAION can cause sudden vision loss that is often permanent. The extent of vision loss varies, but the effects can create lasting challenges for people diagnosed with the condition.

• Vision loss: NAION typically affects one eye and can cause partial vision loss, including changes to central or peripheral vision. Some people may later develop NAION in the other eye.
• Changes to daily activities: Depending on the extent of their vision loss, people with NAION may need to adjust how they drive, read, use computers or perform other everyday activities.
• Impact on work: These changes in vision may also make certain job duties more difficult or prevent some people from continuing work that requires particular levels of visual acuity.
• Financial costs: A NAION diagnosis may lead to expenses related to specialist appointments, testing and ongoing medical care. People whose vision loss affects their work may also experience lost income.

The effects of NAION can extend beyond the initial vision loss, particularly when they affect a person’s work or daily activities. People who developed NAION after taking Ozempic, Wegovy, Rybelsus, Trulicity, Mounjaro or Zepbound may have legal options, and attorneys are currently reviewing these claims.

Frequently asked questions about the Ozempic vision loss lawsuit

Is there an Ozempic vision loss lawsuit?

Yes. People who developed NAION after taking Ozempic and other GLP-1 medications have filed lawsuits alleging the drugs caused their vision loss and that manufacturers failed to adequately warn about the risk. 

Is there an Ozempic class action lawsuit?

The Ozempic vision loss lawsuits are not currently proceeding as a class action. Instead, individual lawsuits are being coordinated in a federal multidistrict litigation (MDL), which allows similar cases to move through parts of the legal process together while each person maintains their own claim.

What is NAION?

Non-arteritic anterior ischemic optic neuropathy (NAION) is an eye condition that occurs when blood flow to the optic nerve is reduced, causing sudden vision loss. There is currently no proven treatment to reverse NAION, so vision changes are typically permanent.

NAION usually affects one eye, although the condition can later develop in the other eye.

What are the symptoms of NAION? 

NAION typically causes sudden, painless vision loss in one eye, often noticed upon waking. Some people experience blurred or dimmed vision, loss of part of their visual field or difficulty seeing contrast. NAION requires an eye examination to diagnose, as vision changes can have many possible causes.

Can I file a lawsuit for blurry vision after taking Ozempic? 

Blurry vision alone does not meet the criteria for this Ozempic lawsuit investigation. Attorneys are currently reviewing claims from people who were formally diagnosed with NAION after taking Ozempic, Wegovy, Rybelsus, Trulicity, Mounjaro or Zepbound. If you have a NAION diagnosis and are unsure whether you qualify, please submit the form for a free case review.

How long do I have to file an Ozempic lawsuit?

The deadline to file an Ozempic lawsuit depends on factors such as where you live and the circumstances of your claim. Speaking with an attorney sooner can help you understand which deadline may apply to your claim.

Is there an Ozempic vision loss settlement?

No Ozempic vision loss settlement has been announced as of August 2026. The federal NAION litigation is still ongoing, and there have not yet been any publicly announced settlements resolving these claims.

How much could an Ozempic vision loss lawsuitbe worth?

It is too early to know how much an Ozempic vision loss lawsuit could be worth because no settlement amounts have been established for NAION claims. It is important to know that no outcome or amount of compensation is guaranteed. The value of an individual claim may depend on factors such as the extent of vision loss, medical expenses, lost income and how the injury has affected the person’s life.
