Mounjaro & Eye Health: What You Need to Know

1. Mechanism of Action

• Mounjaro is a medication that mimics the hormones GLP-1 and GIP to help control blood sugar and support weight loss.

• It does not directly target the eyes or vision pathways, but it can affect blood vessels throughout the body, including those in the eyes.

2. Warnings in the Prescribing Information

• The official FDA label for Mounjaro mentions a risk of worsening diabetic retinopathy (a type of eye disease caused by diabetes), especially in people who already have eye problems.

• As of June 2024, there are no warnings about other specific eye diseases (like NAION or glaucoma).

• The FDA recommends regular eye exams for patients with diabetes who are starting Mounjaro or similar medicines.

3. Expert Opinions & Guidelines

• Leading organizations (such as the American Diabetes Association and EASD) recommend an eye exam before starting Mounjaro if you already have diabetic eye disease.

• Experts urge caution when starting Mounjaro in people with severe diabetic retinopathy.

4. Eye Risks vs. Other Medicines

• Like other GLP-1 receptor agonists (such as semaglutide/Ozempic), there may be a risk of worsening existing diabetic retinopathy if blood sugar improves very rapidly.

• No evidence at this time links Mounjaro to other serious eye conditions unrelated to diabetes.

5. Patient Monitoring Advice

• If you notice changes in your vision (blurry vision, floaters, sudden loss of vision), contact your healthcare provider right away.

• Regular comprehensive eye exams are important—especially if you have a history of diabetic retinopathy.

6. Real-World Use

• Since its approval, thousands have used Mounjaro; reports of new or worsening diabetic retinopathy are rare but possible—mainly in those with pre-existing severe disease.

• Ongoing research is monitoring long-term safety related to vision.

Get a Baseline Eye Exam and Regular Eye Examinations

• Baseline Exam: Before starting Mounjaro, it’s important for people with diabetes—especially those with a history of diabetic eye disease—to have a thorough, baseline eye exam performed by an eye care professional. This exam helps determine if there are any signs of diabetic retinopathy or other vision problems before treatment begins. Knowing your starting point allows your healthcare team to better assess any changes that might occur after beginning the medication.

• Follow-up Eye Examinations: While using Mounjaro, regular follow-up eye exams are recommended, particularly for those who already have some degree of diabetic retinopathy. These checkups help detect any early signs of worsening vision so that action can be taken quickly if needed. If you notice new symptoms such as blurred vision, floaters, or sudden changes in sight at any time while on Mounjaro, you should contact your doctor immediately. Keeping your healthcare providers informed about changes in your vision and attending scheduled appointments can help ensure that any potential issues are caught early and managed effectively.

• Routine Monitoring: Is especially important because rapid improvements in blood sugar—while generally beneficial—can sometimes cause existing diabetic retinopathy to worsen temporarily. Your healthcare team may adjust the pace of glucose lowering or coordinate closely with your eye doctor to minimize risks. By taking these precautions, you can help protect your eyesight while benefiting from Mounjaro’s effects on blood sugar and weight.

Quick Tips:

Mounjaro Vision Loss Lawsuit Update

Key updates on the Mounjaro vision loss lawsuits include:

• Separate Proceedings: The vision loss cases are currently separate from the main Mounjaro multidistrict litigation (MDL) which focuses on gastrointestinal issues like gastroparesis (stomach paralysis).

• Motion to Consolidate Eli Lilly and Company and Novo Nordisk have requested that the vision loss lawsuits be consolidated into a new, separate MDL to streamline the legal process.

• Upcoming Hearing: A Judicial Panel on Multidistrict Litigation (JPML) is scheduled to hear oral arguments on December 4, 2025, to decide whether to centralize these vision loss claims in federal court.

• State Court Actions: In New Jersey, the state Supreme Court has already approved the consolidation of vision loss lawsuits into a multicounty litigation (MCL), separate from the state’s gastrointestinal claims, and assigned both to the same judge for management.

• Manufacturer Stance: The manufacturers, Eli Lilly and Novo Nordisk, maintain that their medications are safe and effective, arguing that current studies are insufficient to establish a causal link between the drugs and NAION.

• Ongoing Research: Medical literature and studies have noted a potential association between GLP-1 drugs and vision issues, prompting calls for more research to confirm the findings.

• No Mounjaro Class Action Lawsuit: The cases are being pursued as individual personal injury lawsuits within an MDL structure (or MCL in state court), not as a class action lawsuit. This allows for individual damages to be sought based on each person’s specific injuries.
