It works every time I use it. 100% effective now it is the only medicine I use gor relief from allery symptoms

This is probably the best product on the market for allergies as far as pills are concerned. Fast acting relief!

Really does work fast! I can even skip a day or two & still feel great. Won't go back to the others.

Zyrtec helps me maintain my sinuses daily & keeps me on top of the weather daily. Go Zyrtec! Quick relief!

I have tried a lot of products including precerptions. Zyrtec works better for me then any thing else.

I've tried many different over the counter allergy meds and so far this one works the best for my allergies.

I can always count on Zyrtec to help with my allergies and not make me drowsy. I would not recommend any other brand, but Zyrtec.

This is the only product that I have found to help relieve my allergies without having to go to the doctor.

I use this product seasonal--it always works! I can cut it in half when the pollen count is down and I still get the relief I need.

The only allergy medication I use every single day. Starts to work after about 15 minutes and last all day (24+ hours). Couldn’t live without this.
