Since starting Guaifenesin, I often wake up with sticky deposits in my eyes. What is this?
Most often guaifenesin helps your body rid itself of protein-like material in the eyes (especially in the morning). It is what the group not-so-affectionately calls “morning gunk”. These symptoms also seem to cycle with the purging. You can use saline eye drops or other non-mediated eye drops to decrease the irritation and flush the eye.
