The Australian regulator warns that Ozempic and other GLP-1 drugs may cause a rare but severe eye disorder called NAION, potentially leading to blindness. The Therapeutic Goods Administration (TGA) updated product information after linking 36 cases in Australia to medications like Ozempic, Wegovy, and Mounjaro.
What Is NAION and How Does It Relate to Ozempic?
Non-arteritic anterior ischaemic optic neuropathy (NAION) is a condition that damages the optic nerve due to insufficient blood flow. The TGA states that NAION may result in permanent visual impairment, and no treatment has been shown to improve visual acuity outcomes once the condition develops.

Key Findings from the TGA Warning
The TGA first identified the potential link in 2024 after a peer-reviewed study, and continued monitoring confirmed the association. While the condition is rare, patients are urged to seek urgent medical attention if they experience sudden vision loss, including partial loss of vision.
| Drug | Indication | Reported NAION Cases (Australia) |
|---|---|---|
| Ozempic (semaglutide) | Type 2 diabetes | 12 |
| Wegovy (semaglutide) | Obesity | 8 |
| Mounjaro (tirzepatide) | Type 2 diabetes | 16 |
The table above summarizes reported cases, though the TGA emphasizes that the absolute risk remains low.
Should You Stop Taking Ozempic?
The TGA does not recommend stopping treatment without consulting a doctor. Prof Helen Danesh-Meyer from the Royal Australian and New Zealand College of Ophthalmologists stressed that NAION is very rare, while the conditions these drugs treat—such as heart attacks, stroke, and kidney disease—are common and life-threatening.
Risk-Benefit Perspective
For most patients, the benefits of managing diabetes or obesity with GLP-1 drugs outweigh the small risk of NAION. However, anyone experiencing vision changes should seek immediate medical attention.
Key Takeaways
- Ozempic, Wegovy, and Mounjaro are linked to NAION in rare cases.
- NAION can cause permanent vision loss; no effective treatment exists.
- Do not stop medication without consulting your doctor.
- Seek urgent care if you notice sudden vision loss or partial loss.
- Regulators continue to monitor the situation closely.
FAQ
What is NAION?
NAION stands for non-arteritic anterior ischaemic optic neuropathy. It is a rare condition where the optic nerve is damaged due to reduced blood flow, leading to sudden vision loss.
Which GLP-1 drugs are affected?
The TGA warning applies to all GLP-1 receptor agonists, including Ozempic, Wegovy, and Mounjaro, among others marketed in Australia.
How common is this eye disorder?
NAION is very rare. The TGA reported 36 cases in Australia among thousands of patients using these drugs. Prof Danesh-Meyer advises putting the risk in perspective against the common and serious diseases these medications prevent.
