No: This is not a side effect of this particular medicine. Get an eye exam.

No, it does NOT: There can be many reasons for a focally enlarged pupil, some benign such as splashed eyedrops, an Adie's pupil,
but others perhaps associated with neurological disorders.
See an ophthalmologist, and start getting this evaluated.

Anisocoria: I have a reference that does not list anisocoria as a side effect. However, Lexapro (escitalopram) can cause tachycardia, sweating and other sympathetic symptoms. It is sympathetic tone that causes this. Any drops, visine etc.
I would talk to your eye provider o.

Yes, although this: is a rare side effect. Here's a beginning reference, but if you did not have this condition prior to taking Lexapro, (escitalopram) then go to your MD right away.
