My dog takes one tablet every day and it has kept her allergies controlled for years now with no side effects. We tried Benadryl first, but it upset her stomach. Zyrtec never has, and her vet says she can take it for life.

I have always had seasonal allergies..having tried other medications (Claritin, alegra)..this is the only product that works for me, I take every day, 1st thing in morning, to.avoid histamine, I am 58 yrs old male and I highly recommend.

Boy I really have to take this all day all year long because without that I can’t breathe I have allergies to cats dogs and pollen so my allergies are all your round the very bad and I do love my animals so I have to take them every day.

Definitely a lifesaver for spring allergies. I like that it kicks in quickly, is only once a day, and does not make me sleepy. I take it daily when all the flowers and trees start blooming.

Back in 2001, I became extremely allergic to mold. Zyrtec was recommended for me to take at that time. The effectiveness has not worn out yet. It is the best for my allergies.

Pollen has been very very bad this year, all year. Without Zyrtec I would not be able to go outside. It relieves my stuffy nose, watery eyes, and sinus pressure and pain.

My 12 year old daughter just tried Zyrtec because Claritin doesn't work for her at all. She tried the 24-hour 10mg dose, but it only worked for 6 hours and now she's all congested again. Very disappointed, as it was recommended by her pediatrician.

Zyrtec has helped me in my transition into an area that has high winds and lots of agriculture activity which is very hard on allergies. Definitely will use each allergy season.

Besides my allergies I get hives daily from everything and my dr prescribed me zyrtec daily. It keeps the hives away without any problems! No seasonal allergies no hives I’m forever grateful. Slight downfall is that it does make me a little drowsy.

Of all the allergy medications available, these give me the most relief without making me drowsy. They work for a wide spectrum of allergies, from dust, pollen, grass, and pet dander.
