Product warnings across the GLP-1 RA class of medicines have been updated due to the potential for these products to cause a rare, but severe, form of eye disorder.

What consumers should do
If you or someone you care for is using one of the GLP-1 RA medicines listed above, you should be alert to any sign of vision loss.
If any changes are noted, stop using the medicine and seek prompt medical attention.
What health professionals should do
Be alert to the new class-wide warnings in the Product Information (PI) documents for GLP1-RAs.
Advise patients to seek urgent medical attention if they experience sudden vision loss, including partial loss of vision.
The Consumer Medicine Information leaflets for each product will be aligned with the PI document updates and these should be provided to patients, if deemed clinically appropriate, as part of the counselling process.
