I'm 59, have had unusually bad allergy symptoms this past 5 months. i started taking zyrtec (cetirizine) a few x a week. now my eyelids are perspiring.

More info ?: I presume that you have hay fever but uncertain as to whether the "perspiration" comes actually from the eyelids or the eyes. In allergic reaction, the eyes often tear and itch. If so an eye drop containing an antihistamine may be helpful especially if Zyrtec (cetirizine) failed. Consult an allergist if the tearing come from the eyes, a dermatologist if from the eyelids.
