Zyrtec works almost immediately not matter what time of day i take it . Other allergy meds worked because they knocked me out... Unlike Zyrtec which is non drowsy. Its (Zyrtec) is the best thing that ever happened to me!!!

I take this every night. It can make me a little drowsy if I take it in the mornings. This is the only allergy company that helped ease my allergy symptoms. It is worth the price.

Purchased this product for my daughter who recently moved in with a room-mate with 2 cats. So far she's had no issues with the usual cat allergies. Thanks!

This product is the product I use. It's easy to take. It lasts long and is very effective. It's non - drowsy too and no side effects. I even use the children's zyrtec for my daughter

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.

Zyrtec is my number one always recommendation. It is the best allergy medication. It works and doesn’t make you sleepy. One a day since I was 12 - over 20 years. And it still works like a charm.

My allergies have been terrible this year. This little guy has been a life savor for me. This is the only OTC medication that I can buy that actually works.

After I took Zyrtec for a few days my feet and ankles swelled to horrible sizes. After I looked online I found that this has happened to many people. I stopped taking Zyrtec and within a few days the swelling went down.

I take this year round for my allergies. It does work for twenty-four hours straight, which is really nice! It doesn't make me drowsy or sleepy. That's a huge plus.

I have the worst allergies! Zyertec is a must in our household. My son is one and he is also on liquid zyertec. We both swell up and sneeze nonstop! Zyertec helps us both so much!! I love that it's nondrowsy but still kicks allergies in the butt!
