Is it okay to take nasacort or flonase occasionally if I take xyzal daily? I was prescribed the xyzal for hives I was getting from chemicals and additives I work with at a chemical plant where liquid and powder polyesters are made. I an a lab tech and a make samples of powder coatings using the powder polyesters. But I still suffer from allergies like mold and pollen. My eyes wil get blood red and feel like they have sand in them and i ll sneeze and cough sometimes. I wear a mask when I cut grass and that helps. I just need something that will help me with these allergy symptoms. I am 54 years old and I did not have allergy problems until i hit my forties.
