Cetirizine
"Good for my runny nose, sneezing and watery eyes and itchy eyes due to the allergy with dust, pollen or any other thing like dog and cat's fur, even chemicals and food especially nuts. But doctor's give 10 mg a day and its been good since; although I am taking it less and less as and when I catch those allergies. Causes me some drowsiness and constant yawning!"
