I think it works great for allergy symptoms, however, it makes me extremely tired and hungry. It doesn't effect my children this way, just me. It's every time I have taken this brand.

I have never experienced such severe drowsiness as i have with this medication. I thought i would kick my allergies but i am so out of it i do not think i can drive home! Perhaps only take this at night!

I just starting taking Zyrtec and the product contains lactose as an inert ingredient. I am quite lactose intolerant and it upsets my digestive track. Do you have a formulation that does not include lactose as an ingredient?

Zyrtec is the only medicine that helps my allergy symptoms. I've even tried taking a generic and it is not effective for me - I always go back to the original!

I keep these in The medicine box because everyone in our house has an allergy to something. It works well. It’s taken in the morning and won’t need another until the next t morning.

I really like the single doze packaging, so i can put a couple everywhere and dont have to worry about having to many bottles. The drug kicks in fast, but I got really tired after taking it. so it's best to take it before bed.

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

Tried and true allergy medication. I’m allergic to cat/dog hair so on days when I know I’ll be around someone’s pets, I take this and am fine for the entire day. And compared to Benadryl, it’s nice to not feel so tired throughout the day.

Ths is the brand of antihistamine that was recommended by my family doctor for seasonal allergy and I have been using this product for several years. I am very satisfied that this product works for me and took care of my allergy with no side effcts

I have been using Zyrtec for years, it does a fabulous job with my year round allergies, I have been taking it since it was a prescription medication. I love it, and have & will continue to recommend it:)
