| 1 | For nasal allergiesand sinusitis | Started giving myson zyrtec in the mornings which made him groggy- so switched to night.After 2 weeks , I forgot a dose.He woke up at 1.30 a.m. with violent shaking and visual hallucinations.I thought he had a bad nightmare-it did not help that he also had a viral fever at the point. Next two days I gave zyrtec he slept through the fever. Then I missed a dose again and pronto he was up at 1.35 am with the exact same symptoms of seeing lights and monsters.He has never had such episodes before and reading all this definitely points to Zyrtec interefering with the mental state. He is definitely coming off Zyrtec. | To top it all it did not relieve his sinus sysmptoms either. | M | 4 | 14 days | 11/22/2005 | 1 | allergies | Severe rage, insomnia | 4 yr old DD would have bouts of SEVERE RAGE, couldn't sleep - not worth it... it only slightly helped her allergies | F | 4 | 3 weeks 1X day | 3/15/2011 | 1 | allergies | I was in tears today with my 4 yr old daughter; she was soo negative and moody, throwing tantrums and being defiant. She usually is the sweetest child, caring and helpful. She was soo rude, saying no and actually pushed her little sister today in frustration/anger. Thank u sooo much for this site, i am no longer giving her this medicine. thank god i didnt keep her on it longer!!!! | F | 4 | 5 days 1.5 ml 1X day | 1/2/2011 | 1 | pet allergies/allergic rhinitis | aggressiveness, irritability, drowsiness, extreme anger and mood swings, very emotional, excessive crying | My 4 year old son has taken Zyrtec and Nasonex on and off for the past year after his dr. prescribed it. While it worked great for his allergies, I feel it completely changed his personality. Like many other parents on here have said, my once sweet loving son turned into a demon child. Hitting other kids, throwing toys, becoming very angry over mild situations with other children, very defiant, just a real nightmare. We stopped giving him the medication because we were just scared of the way his behavior had changed and we saw improvement for the most part. Of course we were still giving it to him on and off as needed when his allergies would really act up so I think that's why his behavior never really improved fully. I decided to give it to him last night because his allergies were really bad and today was the worst day I've ever had with his behavior. I googled zyrtec and irritability and this site popped up. It didn't pop up a year ago when I researched zyrtec side effects. | M | 4 | 1 years | 8/21/2008 | 1 | allergies | my 4 year old has been taking Zyrtec for 5 days and over the past couple days he's been tantruming much more than anytime in the past many months. I did a web search on zyrtec and behavioral problems in kids because he's increasingly not been able to deal with situations that he usually would be able to handle -- finding this website and the many, many comments about similar reactions to zyrtec quickly convinced me to stop giving zyrtec to my son. | M | 4 | 5 days | 5/3/2008 | 1 | Seasonal | My 4 year old daughter took it and immediately became a different child. Crying over everything, irrational behavior, loss of interest in things she normally enjoys. | Kicking this med to the curb... | F | 4 | 2 days | 3/18/2009 | 1 | Eczema, allergies | Out of character temper tantrums, throwing his body on the ground, inconsolability, severe frustration and crying attacks, fatigue, and difficulty waking in the morning. | We will stop use of this drug immediately and go back to Benadryl. | M | 4 | 4 days | 5/23/2008 | 1 | Severe allergies | My 4 year old daughter has severe food and environmental allergies. She was prescribed Singulair and Zytrec at the same time. She had only been on the medication one week and she started to act like she was possessed. She went from a sweet little angel to a child with sever behavorial outbreaks and was extremely emotional. After finding this site I called her allergist and they told me to stop the medications immediately. My question is.... Why wasn't I told this was a possible side effect in the first place????? | Do not give this drug to your child. | F | 4 | 1 weeks | 6/11/2008 | 1 | possible allergies/asthma | This drug affected my 4 year old son's sleeping and waking hours. He had five or six night terrors that he could not wake from every night. His behavior changed during the day, from a sweet mild mannered boy to a hyper, manic, agressive and angry preschooler. I came here and read all of the same side effects that other children were having and I stopped giving him Zyrtec. This upset our family so much that I wrote a blog about it: http://raisingcalifornia.blogspot.com/2009/10/zyrtec-is-evil.html | Don't give this to your children! | M | 4 | 6 weeks | 10/21/2009 | 1 | Dust mite allergy/allergic rhinitus | The allergy doctor prescribed Zyrtec for my 4 yr old son to help alleviate the symptoms leading to his wheezing cough/respiratory conditions. Pretty soon I noticed that our normally easy-going, sweet boy turned aggressive, and completely over-reacted to things which frustrated him. His heart seemed to be racing faster than normal also. I realised this started the first day he was on Zyrtec. | This one has been tipped down the sink! I'll be looking for more natural alternatives. Should have known better than to trust a pharmaceutical drug! | M | 4 | 5 days 2.5mls 1X day | 6/7/2014 | 1 | Seasonal allergies | My son was put on Zyrtec from his pediatrician. The first week he was good then the next week my son started breathing deep and said his heart was beeping fast took him to the ER twice his oxygen was good but they said keep a eye on him . He did not sleep well at night and took him forever to get to sleep. I took him off the Zyrtec to see what would happen and all of his symptoms went away. Then 2 weeks later I tried it again because his allergys were acting up . Guess what same thing deep breathes and his heart racing again. I will never give him Zyrtec again. Have to find something different! | 4 | 1 months | 1/18/2016 | 1 | My daughter's allergies | Anger, aggressiveness, tantrums, no empathy, anxous | My daughter has seasonal allergies. She has been having uncontrolled rage at home & school. Her school has just started & my husband & I were getting phone calls from the principal's office for disruptive outburst, defiance & destructive behavior. We were beside ourselves. My husband said it must be the zyrtec. He said while he was on it he felt anxious and irritable. We've decided to take her off of it immediately. A 4 year-old should never act out like she did. It broke my heart to watch her anger consuming her and her thoughts of herself. She would tell us we did not love her anymore & wants to runaway. Looking back on the times she was not on it she was calm & very pleasant. I feel so terrible that she had been on this drug on & off for a couple of years and never linked it until now. Get rid of the bottle if you are giving this to your own child. Stuffy noses are easier to cope with than an enraged child. | F | 4 | 2 months 5mg 1X day | 8/18/2016 | 1 | Clearing of throat | After starting Zyrtec my daughter the next day began to strug her shoulders, constantly. I stopped the Zyrtec 3 or 4 days after. She's still doing the shoulder shrug when will this end :( | F | 4 | 4 days 5ml 1X day | 8/23/2020 | 2 | Seasonal Allergies | My 4 yr old experienced severe depression (as I call it considering she is 4). She withdrew from her favorite activities, like singing and dancing, stopped eating her favorite foods, would constantly say she felt like crying or she was sad. Did not want to go to school, would wake up ALL night long with nightmares, said her sheets were bumpy, it was crazy and my family was going crazy. She was extremely clingy and weepy, she also would have outbursts of crying or whining for no apparent reason. Took her off the zyrtec and within two weeks, I had my joyful, loving, playful, full of life daughter back. | Never taking zyrtec again, especially for extended periods of time for children....NEVER! | F | 4.5 | 2 months 5 - 7.5mg 1X day | 6/15/2010 Patient History | 1 | Allergy | Our daughter started taking Zyrtec at 2.5 years of age. We thought her terrible two's had kicked in, and so we waited and waited as our little girl went from sweetness to an utter nightmare. She would fly into violent rages at the slightest disappointment, most disturbingly, slamming her head into the floor/wall/anything as part of her tantrum. She is severely speach delayed, her speech was normal until about two then she stopped developing. She rarely to never slept through the night, we even resorted to putting her on Trazadone because we couldn't handle her staying up forever and then waking all night long. It worked for a bit, then she was back to her old pattern. We got her into a therapist who said she had never seen anything so violent or strange. She also would wake in the night and have tantrums and act as though she didn't know where she was. She would go from normal to pyschotic in an instant and back again. | Reading the comments on this website about the pediatric effects of this drug and the apparent lack of information given to parents makes me want to vomit. If this drug is responsible for the 2.5 years of hell we've had to go through as parents I am interested in bringing a lawsuit against the manufacturers. Anyone else? I don't even know how that is done, but something has to happen. We stopped almost by mistake (we ran out and I noticed a change in my daughters behavior and on a hunch, just let the meds go for a bit). A week and a half later she is now beginning to do imaginary play....something she never ever does. I WILL NEVER GIVE HER ZYRTEC AGAIN. I AM FURIOUS THAT I HAD TO GOOGLE THIS MEDICINE IN ORDER TO GET THIS INFORMATION. The bottle should have a skull and cross bones on it as far as I am concerned. I am looking forward to finally meeting the wonderful child I always suppected was inside my miserable child. I feel like a horrible person because it was me giving | F | 4.5 | 2.5 years | 12/27/2005 | 1 | chronic sinus infections | sleeplessness, stomach pain, mood changes: defiant, aggressive, crying, nightmares, hyper | Last spring my son took Zyrtec for the first time. For two weeks he was out of control. Totally disrespectful, not listening or following directions, hitting and kicking at daycare. Took him off after 2 weeks and symptoms went away. A month ago, Dr. suggested back on it as Claritin was not working. Tried it again (thinking that maybe last years issues were caused by something else). Same thing happened. He cannot concentrate, refuses to do activities, hitting screaming kicking etc. He will stop taking it tonight after reading 105 pages of negative side effects of this drug. | M | 4.5 | 1 months | 4/17/2008 | 5 | Allergies | Dear Families with children experiencing side effects from Zyrtec, I am seeking legal action. Please contact me if you are interested! NEW EMAIL ADDRESS. | CLASS ACTION POSSIBILITY! | F | 5 | 2.5 years | 7/20/2006 | 4 | pet and tree pollen allergies | None we are aware of yet | The Zyrtec has helped my daughter reduce red- ringed eyes. Before, people were constantly asking us what was wrong with her eyes. Also it has helped reduce her reactions around animals. I am worried about long term effects. The comments on this site about emotional reactions many have seen in their children cause me concern; I am going to monitor her behavior closely. | F | 5 | 1.5 months | 12/20/2009 | 3 | Alergy | My son is on both zyrtec and singular. He was checked by a ped. phyc., speech theripst, and attends occupational therapy. We adopted him and he had hypothyiriodism and a deformity of the throat. After a toncil and adnoidectomy he began the meds to help with bad allergy and asthma symtoms. This child has become more and more valcanic in his behaviors. He has such a sweet character yet finds himself explosive and trigger happy with the responces that show extreme irritability. I Prayed last night in utter dispare as to how to address his needs. I saw myself doing a web search on the meds. Not only does this zyrtec show these effects but singular is no less a culpret. | Now I stand very concerned about withdrawl. I will print out this and the singular search I did. Why did all my conserns about these drugs fall on deaf ears all this time? I was asured that these drugs were o.k. over and over. | M | 5 | 3 years | 11/16/2006 | 3 | allergies | although it did help my daughter's allergy symptoms, it was not worth the emotional side effects she seemed to experience -- sadness, irritability, fatigue, depressed. I took her off Zyrtec, and she is back to her happy, normal self. | F | 5 | 2 months | 1/12/2005 |
