This one is my favorite of the allergy medicines it has worked with me and my kids as well hey doctor told me years ago to try it because my oldest son had allergies really bad it always worked really good just wish there would be some sales on it and the price is a little high

Zyrtec works better than anything else I have tried. Dries up my watery eyes and stops the itching. Only con is I cannot stay awake once I get home from work every day. Knocks me out. I do get a great sleep but have a hard time waking in the morning.

As soon as it starts getting warmer in the spring, I immediately start taking Zrytec every night before bed and it's a day saver! If I don't take this every night before bed, the next day I will be stuffy and my head will feel full and cloudy! I can't tell you how many times I have had to call out of work because my allergies are so bad but this pill stops that! Sometimes when it's really bad out I will also use a nasal spray, but this pill is always the number thing I need to make it through the day! Highly recommend!

My doctor suggested these as a way to help the symptoms of my seasonal allergies without a feeling of drowsiness. The first time I took one I thought “is this how normal people breath?!” The relief was SO welcome and the results were immediate. The more I took it however the more I noticed complete exhaustion on my end. I know my dr said they didn’t cause drowsiness but if I take one for any reason at this point I’m tired to a point of nonfunctional. It may just be me, I do tend to be sensitive to medications, so take that with a grain of salt. For the price and the results if you a person who doesn’t experience issues with side effects this is 100% worth it.

I have both seasonal and mild pet dander allergies, and taking Zyrtec every night has made them manageable. It significantly cuts back on my sneezing and my reddened, dry eyes. It's super affordable, too, especially in larger quantities. It doesn't make me drowsy either, which is very helpful!

This is my go to allergy relief if I still have to work that day. I don’t think it lasts 24 hours, for me probably 8-12 hours. I think Benadryl Allergy Ultratab Tablets are better for total relief but, the Zyrtec 24 Hour Allergy Relief Tablets Cetirizine Hcl 14Ct don’t put me to sleep and I can still function while getting relief!

I have taken this each fall for years. I usually begin it when I have a 2-week window to adjust to it. It causes me to sleep hard at night, and have a hungover feeling for almost 2 weeks. After that, I have no side effects. I tried Claritin before trying this medication, with no improvement.

With the allergy season upon us, Zyrtec has really been good to me this year. Every year it’s different medication that works but Zyrtec has kept me sane for two years now during allergy season. You just have to consistently take this medication for it to work.

unfortunately PEG's have been added to this product - after 7 years, I can no longer tolerate this med. Allergy to PEG/petroleum etc -caused bad reaction. Switching to another brand without the long list of additives. Guess cost effectiveness overrides good medicine.

First, I want to say that I'm sure, as with all drugs, not everyone experiences negative side effects. I'm sorry those that have are suffering. I took Zyrtec for 20+ years, stopped for a year and the only result was a runny nose from sinus drainage. I have recently started it again with the same great results as before.
