My husband was having pretty bad allergies so his doctor recommended this. My allergies were bothering me a bit so I decided to try it too. We both had the same experience. The first night you take this, you sleep well. The second night you take it, its soporific effect is magnified and you feel massively hung over the next day. I didn't take it again after the second night but I had weird dreams for 3 - 4 nights after that second dose. I might take again if I am having severe springtime allergies and can't sleep but will likely stick to Allegra.

I have had 2 cats and never been allergic to them. We just adopted a cat and I seem to be allergic to her. I bought Zyrtec and have taken as directed for 5 days. It has not helped at all. I have itchy eyes, runny nose and the top of my mouth itches. Can I take 2 tablets?

Being from and living in Alabama, this stuff is a must for spring pollen season. I can get up and my entire car will be covered in a 1 inch layer of yellow pollen. It's unbearable without any meds. This gives me relief within 30 mins and lasts all day.

Suffered for three days hacking away ! Tried Claritin and musinex... still hacking - no sleep ! Last night decided to throw a Zyrtec into the mix( had already discontinued Claritin) and boy am I glad I did ! Within five minutes( I’m not kidding ) I could feel improvement and within fifteen minutes post nasal drip cough and non stop drip down my throat had stopped !!!

Zyrtec or Cetrizine HCL is an allergy medication by Johnson and Johnson, It is a highly recommend second generation antihistamine. Unlike the older first generation antihistamines Zyrtec causes less drowsiness. It's not as cheap as some antihistamines but the quality makes up for the price. Zyrtec Allergy 24 Hour Tablets 70Ct

My whole family takes this 10mg pill everyday. It has been extremely helpful with our allergies. The price is a little expensive, so sometimes I need to get the off brand that is compared to the name brand. It does seem to help all day with just one pill.

I live in Texas. I have suffered with a winter allergy for years. I have used everything but nothing helped. Finally my doctor gave me a nasal spray prescription and said to get some Zyrtec while I was waiting on the prescription. I did what he said. Within the hour I felt better than I had in months. Now I have my Zyrtec on hand and from mid September through late January I take one in the morning and I go all day.

This product is great! I have been taking a prescription nasal spray for about ten years, but this year, my allergies went into overdrive. Even after using my prescription, my nose was constantly running and my eyes were always watery. I even had raw spots from wiping my eyes and nose constantly! My Doctor told me I could add one of two OTC medications, so I tried Zyrtec instead of the other one he recommended, and I couldn't be happier! I've been taking them for about six months, and the results are amazing. It has cleared up all of my symptoms, but it doesn't leave me feeling wired or sleepy. This product has been a lifesaver to me, especially since our 'seasonal allergy' season has become an all year event. I highly recommend this product, especially if other products leave you wired or sleepy, because Zyrtec doesn't.

I've always taken Claritin, so when allergies hit this year that's what I took. But it didn't work, and I almost had to cancel my vacation. My friend gave me Zyrtec; my allergies were relieved; and I was able to go to the Grand Canyon with all my friends.

I’ve tried this but for some reason it makes me tired. It’s supposed to 24 hours. But if I take it at night then I’m not so tired the next day. But it does help with allergy’s. It’s very expensive. Yes I recommend it if you can afford it. I found an off brand that works just as well
