You take 1 a day and they don't make you tired. They are very effective they help alot I have 2 cats and a dog and before taking these I was sneezing and my eyes were itchy but not any more. They have no taste or smell.

My Dr. told me take this and I couldn't tolerate it. Side effects were too bad. I let my husband try them because he has really bad allergies and he didn't like them either. And he can take most medications.

I love these there a must have for me great quality and price is awesome I have bad allergies and these allow me to be outside and enjoy the outdoors !!!!

I love taking Zyrtec during my allergy seasons. It keeps me feeling healthy and stops my sneezing and itchiness. They are very effective if you take one each day. I will always recommend Zyrtec!

I'm grateful for Zyrtec, it really has worked well for me. It works relatively quick and 1 pill lasts for 24 hours, which is great. I did not experience any drowsiness or any side effects, and for that it is worth the price to me.

My husband takes these cause we have 2 dogs and a cat and they can tend to make him have a hard time breathing. Zyrtec is the only brand that seems to help.

Non drowsy, Effective to relief those recurring allergy symptoms. Is a standard go to in our house for chronic allergy suffers, it work's well. Cost's little more than other's but much more effective

I started using Zyrtec just a few months ago and it is hands down the best allergy medicine I've ever tried. Really effective and fast - workd really well to keep my allergies under control

This is a great allergy medication to be taken at night or even during the day.. Great if you have the sniffles from allergies to pollen or dust, etc.

Zyrtec is great for seasonal allergies. Use to have this prescribed to me as a kid but then it became over the counter which is great because you do not need a prescription. Starts working very fast and last for a while
