Great fast working allergy medicine. I normally have to switch in between. Effective and relief is long lasting. Have been taking this brand of allergy medicine since was younger. Will definitely keep using it

Certainly my experience is different than many people I know, but Zyrtec did nothing to relieve my allergy symptoms. This is an expensive otc medication that, based on my own experience, I will not purchase again.

I have severe allergies so this only works for about an hour for me. I have to use prescription allergy medicine. When I was a kid I used Zyrtec and it worked just fine.

I just took one because I couldn't breath. Bad allergies in June still here in Texas. Worked very fast I just hope they stay true to not causing drowsiness I have to work.

Before using Zyrtec, I did hot want to go outside during allergy season. Before Zyrtec, myy red, itchy eyes and runny nose kept me from golfing and just enjoying the outdoors.

I normally use Claritin. My friend gave me Zyrtec to try snd I'm a believer. I suffer from pollen nearly 5 months out of the year and voila, your product works! Thanks Zyrtec.

I love it I use it all the time all your round and I have no problems I've tried everything else or doesn't work as good as this thank you for making it

Works great for seasonal allergies. I like that it is a 24 hr. Tablet. I did not find that it made me drowsy. It costs more than store brands that are just as effective. Still recommend. 

Zrytec is the best 24 hour allergy medicine I have ever used. It not only stops the runny nose but does not dry out the sinus cavities that cause a "face" ache that some allergy medicines cause Mary

I have been using this product for a number of years. When I stop using it for any length of time, I notice the difference immediately. My favorite anti-allergy medicines!
