What is this Varenicline nasal spray?

Simply put, this is a medicine that treats a condition called Dry Eye Disease. It can be found in the market under the name (Tyrvaya). The surprising thing about this is that it is not a medicine that is applied to the eyes, but a nasal spray. Imagine how dry eyes can be cured by spraying a medicine into the nose.

Here's how it works: There's a nerve inside our nose that's directly connected to the glands that produce tears in our eyes. When you spray this medicine called Varenicline into the nose, it stimulates that nerve. That stimulation causes our body to produce more tears naturally. This way, instead of using artificial tears, the medicine works by moistening your eyes with the natural tears your body produces, reducing dryness.
