I notice when I stop using! Works great and doesn't make me tired!

This product did not help me at all. But it was the best for my son.

This is the only over the counter that helps me! It is a must have!

Only thing that helps me and my son with our severe year-round allergies.

great product. i have been using for several years.

I use this product all year for allergy relief works well for itchy eyes and runny nose.

I have tried a variety of products but none have worked for me like Zyrtec!

My whole family of 5 takes Zyrtec year round and it works great.

Best allgery for nose and eyes watering stops sneezing

Zyrtec does the job for me, 95% of the time, and I have terrible allergies!
