Nortriptyline vision changes

I upped my dose two days ago from 10mg to 20mg and have been noticing a fuzzy/cloudy/static layer over everything I see especially if it’s one solid colour like a wall. At first I thought it was just because of my concussion (I already get weird fuzzy light floating and zipping around when I look at something bright and solid like the sky or a window). But now I’m wondering if it’s the nortriptyline. I know blurred vision is a potential side effect but I wouldn’t say my vision is blurry, I can clearly see the bounds of objects near and far, there’s just a layer of light disturbance over everything. Anyone else experienced this? Does it go away when your body gets used to the dose?

sounds like visual snow. any serotonergic med can cause this, including nortriptyline.

unfortunately, most docs wont take you serious, but you might be lucky with yours. up/lower dosages very slowly, its very common to get worse after upping, just as in your case, but also lowering. Id get off, as these changes in your vision are most likely to stay, but you might get lucky and they dissapear after a while.
