Reviews for Cetirizine to treat Hay Fever
Review by Nicfing (taken for less than 1 month):
Zyrtec (cetirizine): Took Zyrtec on the advice of my ENT for chronic sinusitis from hay fever. It worked wonders on my sinuses but I can not function on it due to extreme drowsiness and fatigue. I am going to have to stop taking it!
Zyrtec (cetirizine): Zyrtec relieved me of my allergies (except for my worst days), but the side effects were horrible--drowsiness being the worst. I took it at night, however, it still made me so drowsy during the day that in school I fell asleep in every class. Eventually my friends convinced me to stop taking it because they had experienced the same thing.
Zyrtec (cetirizine): Zyrtec works well in combating allergies as well as allergic rhinitis. The best I've found.I take at night about an hour before bedtime and sleep like a baby all night. Love it. First time in years I can say I feel great and not congested from allergies.
Review by Ragweed sufferer (taken for 2 to 5 years):
Zyrtec (cetirizine): Zyrtec works incredibly well for my severe ragweed allergy. However, each fall I've noticed it's making me more and more drowsy, to the point that I don't want to do anything and I'm needing naps in the afternoon. I think I'm going to have to discontinue it, which is frustrating because it works much better than the other meds I've tried.

cetirizine: I have taken cetirizine daily for a few months and have noticed my allergies are now much more under control. Unfortunately it hasn't been a complete package: I also use azelastine nasal spray for allergy prophylaxis. Though it is a common side effect, I never experienced drowsiness, even when taking it early in the day.
cetirizine: It worked great on my seasonal allergies. I've had a real problem with insomnia. Decided to check for causes and here I am. I've been extremely sleepy during the day, but chalk that up to the lack of sleep. I can't sleep more than 2 hours nightly. It's killing me! After reading all these reviews, I'm going to skip it today. I hope I don't begin to itch like so many of you did. It's a shame. It made a world of difference to my head and sinuses.
cetirizine: I have been on cetirizine for about 2 years now. I am now off it now. This medicine can cause severe itching when you come off of it. A full body itch that is completely distracting and makes you want to tear all of your skin off. I have tried to ween myself off of it, lowering my dose from 20mg to 10mg per day gradually over time, but this has had little effect. After about 48 hours of not having the medicine my body goes into full itch. I have to wear winter boots and oven mitts and jean clothing to prevent myself from itching.
Zyrtec (cetirizine): It really did not work for me. My eyes itched a bit less, but my nose just kept itching and running. Also sneezed multiple time after 1st dose. Tried a 2nd tablet 4 hours later with no noticeable results. This may work for some people but I get better relief from Benadryl, which works well but causes drowsiness.

Zyrtec (cetirizine): I just took Zyrtec for the first time yesterday. It did make me drowsy but I also didn't get much sleep the night before. I took it because my eye was so itchy and watery it had become swollen and I was having trouble breathing. I have had allergies for over 15 years but never took anything before this. Well I don't know if this is an unlisted side effect but I woke up in my sleep cracking up and could not stop laughing for a few minutes even after my husband woke me. I wonder if anyone else had intense dreams while on this medication. I don't take anything else that would cause this.

Zyrtec (cetirizine): Zyrtec worked well for my nasal allergies, but when I tried to stop taking it after several years, I got the skin itch/rash that many have reported. It was worst for the first few days, but now even a year later I still frequently get a skin rash when I get warm (cholinergic urticaria). I can't say for sure that the cholinergic urticaria was a side effect of stopping Zyrtec, but skin rashes were never a symptom of mine until I stopped.

Zyrtec (cetirizine): It works better than any other medicine I have tried. Down side is the itching, which is caused by its negative effect on the liver. Therefore, I do not take it everyday. I have to wait a day or so in between.
Zyrtec (cetirizine): I thought Zyrtec (cetirizine) was great at first because it worked so well on my allergies. I have gained 15 pounds over 1-1/2 years. I didn't think it was related to Zyrtec, but recently figured out that it is. I am an extremely healthy eater (no processed foods or white flours/sugars), a runner and triathlete without weight issues before Zyrtec. I attributed the weight gain to age, hormones and finally my thyroid. Blood tests ruled out the hormone and thyroid issues. I only take HRT & Zyrtec. I stopped Zyrtec 3 days ago and have lost 2 pounds without any changes in diet. I am willing to suffer with allergy symptoms if I can lose this weight.

Zyrtec (cetirizine): All day I have had runny nose, itchy watery eyes, sneezing, throat closing. I finally could not take it anymore I did some research online to determine the best OTC medication to use, Zyrtec stood out the most. I figured that it must be pretty strong due to the fact that at one time you needed a script to get it. I took my first tab at 3:00pm its now 3:18. I am starting to feel the effects of Zyrtec I have not sneezed as of yet my watery nose and eye's are starting to clear up. I'm beginning to breathe easier.
Zyrtec (cetirizine): I have been taking Zyrtec for about 2 years for hayfever. I have noticed that it doesn't seem to be working as well for my symptoms as it did at first. I stopped taking it 3 days ago and now I am experiencing severe itching on my hands and feet.

cetirizine: I have severe seasonal allergies, along with allergies to dust and molds. I used Zyrtec or its generic equivalent for a few months, and it never could keep the severe symptoms under control, like other second generation antihistamines. I stopped after about 4 months of use. Zyrtec seems like a viable option for those with average seasonal allergies.
Zyrtec (cetirizine): This is the only medication that has worked for me so far (besides Benadryl), but it gives me horrible dry mouth and eyes after using it for a few days, and if I take it for longer than that my tongue starts to hurt because of the dryness. I would give it a 10 if it weren't for those symptoms.
cetirizine: Cured my persistent cough, made me drowsy, but also suffered from insomnia and made me feel depressed, wanted to cry at the slightest negative thought or comment, most unlike me.
When I stopped taking pills cough recurred, depression subsided.
Zyrtec (cetirizine): Make the itching stop. I took this for Hayfever and it worked. BUT, it then caused me to have head to toe bumps and itchiness even after stopping taking it. The itching is keeping me up at night. I am hoping to wait it out and never take it again. Also while I was taking it my eyes and face got really, really swollen. I am still not sure if this was from an unusually bad allergy season or the Zyrtec, but I am going to guess it is the Zyrtec because my allergies have never caused this before (usually I just have sinus and itchy eyes).

Zyrtec (cetirizine): I have just decided to stop taking Zyrtec. It worked well on my allergies. However I have had increase in back and joint pain i.e. knee and hip the past two weeks. Not sure it's Zyrtec but felt I'd eliminate it to see if symptoms resolve.
