Hi binx,
eons ago I was given Paxil, when I was having daily hives, to try to calm me or them. 10 mg sample I was given. After one month my eyes dilated, like I was an illegal drug addict or something.

When I showed my eyes to my then Neuro, he said you can't take that drug stop immediately. SSRI class of drug.

Fast forward to a new Neuro, 15 years later, I was given Cymbalta for pain. In one week my eyes dilated complete again. I was taken off the drug and that was the lowest dose in her sample pack too.

So my question to you is:

Do you take a selective serotonin and/or norepinephrine reuptake inhibitor (SSNRI) or SSRI? I never had depression or have used anything fro depression, but these were for off-label use.

I thought my eyes looked pretty, all black with a tint of green around the edge. This was an adverse drug reaction not listed on the print out. Something in my brain did not like those drug.

Some are used for depression or anxiety. Are you on any meds for this? The eye dilation might be a drug you take, not part of the disorder you have. JMO

Maybe this is helpful to you
