Mounjaro 5mg, Blurry eyes

Hopeing wise Mnetters can help. I started MJ in May 2.5mg. 5 weeks ago I upped to 5mg it was around then I noticed burry vision, this is not all the time but fairly frequently. Has anyone else experienced this.
Google says it can happen due to blood sugar changes ( I've gone from eating many chocolate bars and treats daily to seldomly having some ) or dehydration. Which could possibly explain the fact at specsavers last week they said my eyes were dry, I didn't tell them I was on MJ, as didn't think it would be relevant. It wasn't until I got home it crossed my mind that it could be linked.

So useful advice from me except that I love your username. And am jealous that you stopped craving chocolate and treats.
Perhaps see your GP about blurry vision and that you ate on mj and the two might be related?

There Is a possible slight increased risk of optic disc swelling when on these medications so somebody should be looking at the back of your eyes. I don’t mean to worry you; I think odds are it isn’t this, but do get it checked.

They did all that during my eye test last week and it was all OK.

Nothing to add on the blurry eyes, sorry, but has anyone noticed a runny nose?

You may have been pre-diabetic and didn't know it. Mounjaro reduces blood sugar levels. Lots of people who are diagnosed with Type 2 diabetes radically overhaul their diet, and with that, lower their blood sugar levels and get blurry eyesight.

I totally had blurry vision every day until quite recently. It was definitely linked to Mounjaro. My eye health is fine - my eyes have been checked by an optician and also at the hospital for something unrelated to MJ. The blurriness appears to have now gone but it lasted for a couple of months +
