You are eating more calories than u r burning. That is why you are gaining weight. Get the app Cronometer and track your exercise. You can do it. It is not the allergies Ortega Zyrtec. Simple in concept difficult in execution.

All Antihistamines have been found to cause weight gain primarily in women over 40, but especially over 60. It is a function of reduced histamine in the system that causes increased hunger. A better approach to allergies would be taking the antihistamine for several months only during the allergic period, with long periods of no histamine use in between.
