watch for blurred eye vision from levothyroxine

[sue2005]

Has any one ever experienced blured eye vision due to too strong of Levothyroxine. My pharmacist put a warning on my last refil and sure enough blurred vision may be a side affect. It came on gradually but got bad enough I went to see my doctor and got the dosage reduced back. My TSH was very low so they increased the thyroid medication and blurred vision started and kept getting worse. As I said they reduced it back. Hopefully it will get better soon. Be sure you have a very good pharmacist as I do where he put the warning on the medication so I could report it to my doctor when I seen him about the blurred vision.

Welcome.

Wow. That's a scary experience.  I can't say I've ever heard of it but with side-effects, you never know.  My close-up vision has changed since being on the med but that came a bit later.  I did see an opthamologist who gave me a recommendation for reading glasses.  He said my issues couldn't not have been from the med because if it were both aspects of the vision, close-up and far, would have been affected.

Good luck.

OMG, I have very blurred vision and I never made the connection.  I've taken the same dose for many years without problem but since my thyroidectomy one year ago I take a much larger dose. Over the past 6 months my vision has gotten so bad that just yesterday I was looking for an opthomologist in my area to call on Monday. I don't think anything can be done though as I have to take the higher dose for cancer suppression. Oh well, guess I'll get some glasses. Just add that to list of one more thing on my body that's falling apart.

I have had blurry vision ever since taking levo, armour and cortef. I am not sure which medication did it, but it is definitely medication related. My eyes come in and out of focus, almost like an auto-focus on a camera. My levo dose is low, so it may be the cortef. I wonder if all of this stuff which changes the thyroid/adrenal patterns can make the vision blurry

yes I have blurry ey vision when I was hypo and again when I lost weight and I was on too much synthroid.

I went to my annual eye appointment today (I mentioned my blurred vision), and he told me that I have a condition that causes "blind spots" on the cornea and that many people on Levothyroxine get this as a side effect.  HOWEVER, it doesn't necessarily mean that your dosage needs to be reduced (get the levels checked first to make sure, rather than just asking that the dosage be reduced).  The reason I'm saying this is that my eye doctor gave me some eye drops (the regular kid that prevent dry eyes) and told me that this ought to take care of it.  So it may not be as big of a deal as we think.

I have had blurred vision prior to RAI (while on Carbimazole) and after RAI (on T4 med) ...sometimes my eyes stream with water ....which is usually when my TSH is too high.
It comes and goes but I did buy an OTC eyedrop for the tearing and found it fixed it.
So if it was allergies or not, I dont really know.

Lol at Liz94...QUOTE " Oh well, guess I'll get some glasses. Just add that to list of one more thing on my body that's falling apart. "
I'm 50 at the end of the year and BOY do things really start to fall apart once you hit 47! lol
I even tell my Doctor now that if something is wrong...'I dont want to know! lol'
I even delayed my pap smear as I felt I couldnt handle it coming back 'suspicious'......but eventually went for it and all was fineWhen my Doc asks if there is anything else I want ....I always say...Well Doc, I need a grease and oil change! But its now getting where I may have to ask for a 'trade-in' lol.

I do need another checkup though on my eyes as the 27th of this month is one year post RAI and also will be having a full body scan done.
