allergic rhinitis
"I have used Zyrtec for a couple years to reduce my allergy symptoms and avoid asthma flares. I have a dog that causes symptoms if I play too much, or if I touch my eyes. We got a cat about 1 year ago! Zyrtec met the challenge, the cat sometimes sleeps on my pillow. I am still careful about touching my eyes, but Zyrtec has done a great job.  Now that Z is OTC, my doctor switched me to Clarinex, but after a few days I am experiencing symptoms again, swollen lips, eyes, etc.I'm going back to Z!"
