 5  Allergies,sinus pressure,itchiness No side effects. Zyrtec has provided better relief from allergies than Claritin. It has even reduced my allergic reactions to cats. The only time I had a problem was when I was taking benadryl, on occasions of visiting my girlfriend (who has a cat), in addition to the Zyrtec. That cocktail caused eustation tube dysfunction for some time. I avoid mixing my antihistamines nowadays. However, Zyrtec, by itself, never caused me any problems. M 39 2 years

 1  allergies My 7 year old daughter has been on this drug for about 3 years. It controls her allergies 100%. HOWEVER, lately, she has been extremely overly emotional - she cries at everything. Almost every day. After reading all these comments on the side effects of zyrtec on children, I am hopeful that this is the cause of her upsetting behavior. She will never have another one of these pills - we will gave to find some other way to control her allergies. F 7 3 years

 1  Seasonal Allergy Depression, lack of attention span, confusion, and overall ability to make rational decisions My son's grade dropped dramatically once on Zyrtec. His overall ability to function was impaired by Zyrtec. Now that he is no longer on the drug, he is feeling like his old (non zyrtec) self. M 12 20 days

 3  seasonal allergies my 4 year old daughter has been taking zyrtec for 3 weeks now and I have noticed that in that time her stuttering has gotten noticeably worse. She has also been complaining of frequent stomach aches and headaches. My daughter's preschool teacher said that her son who is 11 also had similar side effects. We have stopped this medicine and we will treat her allergies holistically as long as we can. the medication is working great on her allergies, but the side affects fall short of my satisfaction. This medication should not be OTC in my opinion. F 46 3 weeks

 1  allergies extreme drowsiness I took Zyrtec in the evening and woke up the next morning feeling refreshed and with no allergy symptoms. However, approximately 14 hours after taking it, while I was at work, I had the odd sensation that my hands and feet were not connected to my body. Thank god I had the sense to cancel all my appointments for the day and not get behind the wheel of a car, because about a half hour later I felt so tired that it was painful to even try to type. I remember I started crying when I had to reach for the number keys on my keyboard, they seemed so far away! I spent the next 4 hours at my desk, a complete zombie, unable to move. I'd advise anyone taking this product for the first time to avoid driving for at least 24 hours. F 42 1 days

 3  Seasonal Allergies Constipation, pimples on face/chest It is weird that since I started taking Zyrtec that I noticed acne on my face and chest and have become constipated. It did not help all that great with my allergies...needless to say that I will not be taking anymore Zyrtec--it is definitely not recommended! F 27 10 days

 3  Hay fever Sleep apnea! I had never experienced sleep apnea before. My wife reported that my breathing stopped periodically while I was sleeping. I woke up many times in the night, not knowing why. For me, poor sleep yields weight gain. It's a shame. It did a great job of controlling my allergies. If they made a 12-hour version of the drug, it would be perfect! M 33 40 days

 1  "possible" allergies nightmares, acting out, irritable, defiant Zyrtec was prescribed to my 2 1/2 year old. Seemed to work great until she came very defiant, irritable, couldn't sleep. She cried a lot and became very aggressive. We attributed it to the "terrible twos" because she is such a sweet and loving child. I am so glad she hasn't been on it long and we were able to narrow it down to this medication. She is already totally different after just one day off! F 32 2 weeks

 3  sinus headaches due to allergies weight gain, irritability, depression, apathy I quit taking zyrtec due to doctor advice when I had a severe sinus infection...the zyrtec was drying it out and keeping it from draining. Didn't start taking zyrtec again after the infection cleared...CRAZY ITCHING for WEEKS! I'm going nuts! How long does this last? I was always reminded when I ran out and missed for a few days because this itching would begin, but I never knew it would last THIS LONG!! The funny thing is that the allergy symptoms I had before zyrtec did NOT include itching at all. F 33 5 years

 1  Chronic Allergy irrational escalation over small issues turning into rage and tantrum, followed by anger at self about not being able to stop the conflict. Inability to stop chewing lip, Periodic (negative) obsession with looks, "heads too big, face too long", low self esteem, depression "I have no friends". Rage/tantrums stopped within 24 hours of stopping medication, depression/obsession within days, lip licking - may be unrelated - took about 30 days to cease. The kids have been hapily OFF the prescription for about 90 days. Product does a good job of alleviating allergy, but in my opinion the manufacturer is criminally negligent in not disclosing the potential side-effects for smaller children. Does not seem to affect all kids the same, but when the side effects manifest themselves it's heart-breaking. Prescribed to both sons, 6 and 8. The 8 year old seemed to have no problem with the medication. The 6 year old went through a year of progressively more frequent and more irrational arguing and escalation. Then would feel angry at homself over not being able to control it. On an instinct we decided to stop medication to see if it helped. Impact was immediate. He is still a headstrong kid, but he is rational, feels good about himself, and feels in control of hios emotions. Kills me to think of how much confrontaion we could have avoided and the unneccessary emotional conflict it put on my 6 year old. I didn't find this site until after we had stopped the medication, was amazed at the fast impact, and was looking to see if this was a published side effect. Overnight, with cessation of the medication, the tantrum behavior that had built up to almost weekly clashes has been gone for the 90 days since we stopped the dosage. I can hardly find the words to describe my contempt for the manufacturer for not warning consumers to watch for this potential side effect. I hope someone sues them into bankruptcy. M 6 12 months

 1  seasonal allergies Pimples on chest, shoulders, and upper back. Periods of constipation followed by painful, large, and loose BMs. Decrease in energy and water retention/minor weight gain. I have taken Zyrtec off and on over the last few years for my season hay fever, and when I noticed the strange changes happening to my body, I wondered what it could be from. I stopped taking it 3 days ago and my acne and BMs are back to normal and I have lost 3 pounds in what I assume was water weight. Needless to say, I will not be taking Zyrtec again. F 23

 1  Allergies Extreme agitation, screaming, moody, hyper... I chalked his hyper and out of control behavior on just being 3, but when my normally content and well behaved son turned "demonic" I started searching online to see if the zyrtec I have been giving him for almost a week had anything to do with it...seemed kinda strange that almost immediately the same day he started acting out and just being almost impossible to deal with!! I came across this site and read of other little ones that have the SAME side effects! I haven't given him a dose today and plan on throwing this crap out! Back to benedryl at night! M 3 4 days

 4  spring allergies weight gain Very effective at controlling my allergies. I'm perhaps a little drowsy, but I counter that by taking it at night and drinking coffee in the day. In another month, allergy season will end, and hopefully I'll be able to lose the weight. M 33 30 days

 3  spring outdoor allergies irritability, anger issues, cranky, argumentative, rudeness, negative We've had horrible behavior issues that last long for the past few days for no reason at all. Finally tonight it dawned on my husband and I that we just started giving him the zyrtec this week. I'm taking him off tomorrow and hopefully he will be back to his old 7 year old jolly self. It was helping his spring allergies,but we'll have to find something else because I can't deal with those side effects. Also it contains parabens in the ingredients and those are not healthy for humans according to my most recent research. Alot of beauty items in fact are advertising paraben free on the packaging.

 2  seasonal allergies Depression, anxiety, Always irritated and lost pounds of hair becoming almost bald, appetite loss and very very sleepy!!!! Worked only if i took 2 tables a day. Man i had no clue my depression and anxiety were because of zyrtec, i took zyrtec last year for the allergies OTC i tried it for 3 months and i took it regularly for almost 3 months, though my nasal symptoms have subsided i started having eczema and irritated eyes. During that period i had the hardest time in my life i was always depressed not at all interested to speak with anybody and had anxiety related issues.... i seriously thought it was my job search making me that way but now after going through this site i have realized it is the medicine and i even went to the doctor who could not even make out why i had anxiety issues as i never had these problems in my entire life ..... the worst part was once you i stopped taking this medicine i starting scratching a lot and lost so so much hair i thought i was going bald, thought i have recovered all that hair now and as the season has just started i was considering some allergy medicines and came across this site. Thank you guys so much i would not have none ZYRTEC WAS CAUSING DEPRESSION!!! I will meet an allergist and find out if i can get some other medicine. M 24 4 months
