Blurred vision from keppra

[mythreechildren]

I'm on 3000 mg of keppra every day. I had my vision checked 3 weeks ago, got new glasses, and my vision was good for a few days. Now my vision is horribly blurred to the point of real concern to me. I would like some reassurance that it will improve when my medication is changed or reduced. I just know I can't live with this.

Hi mtc,

You should let the opthalmologist and the neurologist know about the blurry vision. Sometimes it can be a reaction to a new eyeglasses prescription (even after two days of good vision). But it can definitely be a sign that you are on too high a dose, or that this just isn't the right med for you, or that something else is going on.

It's hard to predict whether or not any Keppra-related vision changes will go away if you lower your dose -- there isn't a lot of data out there. I have similar questions with Lamictal, which has caused me to have intermittent blurry vision. I haven't been able to turn any studies on whether the blurriness will persist if I change meds.

My eyes/vision is always the first thing to act up on me when I increase a medication dose but it will typically last no more than a week or so. Usually my eyes are sensitive, and my vision is blurry or on the verge of going double. This will usually hit about 1/2 hour after taking the dose and taper off after a couple of hours. Minimizing reading and computer work makes a big difference. On the other hand, I have developed prolonged nystagmus from a medication, and that will be my first warning that a dose is likely too high.
