| 1 | allergies | visual, auditory and tactile hallucinations | My 9 year old son was on Zyrtec for 7 months. When placed on Amoxicillan for two weeks for a sinus infection, he began to experience hallucinations. The doctor thought it might be the penicillan and never mentioned the zyrtec. Had an EEG which was normal. When I realized the side effects of zyrtec I took him off immediately (5 days ago). However, he just had an "episode" again tonight (lasts about 10 minutes). Has anyone had a child experience this??? How long before the side effects go away? | M | 9 | 7 months | 4/17/2007 | 1 | Eczema | My son just turned 9, he started taking Zyrtec when he was 7, his teacher kept complaining about his behavior, he can't remember anything, he looked so lost in the school. He can't sit still, he can't focus on the classwork. His teacher suggested me to talk to the doctor because his behavior just like ADD, I made a research and found this website,I was so shock that Zyrtec will affect the child's behavior so much. I decided to reduce the medicine week by week, now my kid was very good in the school, he remember everything, He completed every sigle classwork/homework. I really think all of the doctors should give the parents warming before the children starts taking ZYRTEC. I feel so sorry for my son. | So many parents has no idea what will happen when their child start s taking this medicine, Please consider not to let the kid take this medicine........... | M | 9 | 2 years | 1/27/2007 | 1 | post nasal drip, mucus, congestion | My 7 year old son was taking Zyrtec and developed very bad behaviors in school, threatening suicide and others, and was very physically aggressive to his teachers. Once I realized that the bahaviors started the same time as Zyrtec, I took him off. One year later, he still has behavior problems, but they are lessening. Last week, I gave him one dose because of terrible itching. He had 2 very bad episodes at school so far. Thereis no doubt that Zyrtec triggered something in his brain. Hopefully it is not permanent. | Since my son was mildly retarded, I don't think he could express how he felt. But when asked why he felt so angry, he always said, I don't know . Something got in my head. | M | 9 | 1 years | 11/5/2007 | 1 | Eczema | agressive behavior, can't focus, can't remember anything, can't sit still, can't pay attention and follow teacher's instruction. nose breeding. always tired | Teacher kept complaining about my 8-year-old son behavior, she even force me to put him as a ADD kid, after I found out this website, I did two things: 1. Reduced the medicine little by little (it took me two months to quit the whole medicine). 2. Transfer my son to another teacher's class. Now four months pass, I just got his report card, he got straight 'A' and citizenship marked as "Excellent".He is still in ADD status but he did not take any ADD medicine, I knew his behavior problem was caused by Zyrtec and Singular (he took two medicines everyday). My suggestion is: Quit those drugs as soon as possible, my son is under the treament of Chinese herb and there is no side effect. you may make a research and find another better way to treat your kid. Good Luck!! | M | 9 | 2 years | 5/26/2007 | 4 | Severe allergies | Facial and body tics | My 10 year old son had been taking Zyrtec for the better part of 5 years. He developed intermittent facial and body tics. If we were ever late on picking up his refill for Zyrtec, his tics would stop. Upon restarting the medication the tics would reappear. Although this medication worked wonderfully for his allergies, I don't think it's worth any risks. | M | 10 | 5 years | 3/3/2009 | 3 | Allergies | OMG. My 10 year old son has had a complete personality change after 4 weeks on Zyrtec. I just googled "Zyrtec irritabiity" and found this site. Thank you. I ordered child behavior books this afternoon because his anger is through the roof. He will never take another one! | M | 10 | 4 weeks | 9/23/2009 | 1 | Seasonal allergies | My 10 year old son. Has been having uncontrollable anger outburst. Also crying easily. I have been doing research to find a cause and help for my son. After reading this I am stopping Zyrtec TODAY notifying his MD. By the other post it seems zyrtec could very possibly be the cause. | M | 10 | 5 years 10 mg | 5/14/2015 | 1 | Seasonal allergies | Anxiety, night terrors, personality change, emotionality, tics | We gave our 10 year old daughter Zyrtec for approx 5 months ...it really affected her badly. We thought it was “tween hormones” at first but she became extremely moody, anxious, fearful, had spasms and just wasn’t herself..to the point where we consulted her pediatrician and took her to a therapist. We finally put two and two together and discovered that the only thing that changed in her life was the addition of Zyrtec. I started researching side effects and my mind was blown! Immediately took her off it and our happy, spunky little girl is steadily returning. It’s been a week and she’s a whole different child. We feel horrible that it took us so long to figure this out, our poor daughter was suffering for too long due to this supposedly “safe” OTC medication! | F | 10 | 5 months 10mg | 10/24/2017 | 1 | Allergies | Rash, irritability, agitation | Should not give to children. | F | 10 | 10 days 1X day | 6/30/2016 | 1 | daughters allergy | this drug is stupid and doesnt work | does not help allergies, and it full of crap, i dont like it, my daughter is still getting horrible allergies. | F | 10 | 1 years | 11/21/2008 | 1 | Severe Hay Fever,possible dust alle | Extreme drowsiness, irritability, slightly depressed/self doubt, thinking something more serious was wrong with her, (ONLY 10 YEARS OLD), UPPER GI (chest) burning/pain, diarreah, just not acting like my daughter when on the meds. | Wow, what a nightmare! CAUTION! Please parents do not give your child this medication! I am going to stick with mucinex for her congestion, and proceed with more natural remedies,ex.(local honey daily,etc.) I'll probably never trust another allergy med with my kids after this! | F | 10 | 8 days | 7/2/2008 | 1 | allergies | So many they will not all fit. The worst is that now my 10 yr old has seizures. And we now have to take her to a specialest. also was told she was ADD and she isnt..... | want to warn all parents,dont give this drug to your child.. Also We the parents want to sue the company who has made this drug.... | F | 10 | 6 years | 5/24/2008 | 1 | Allergies and eczema | My child's behaviour changed when she was on this horrible medication!i swear to God it was a nightmare for me to see how she react with her moody angry mode and keep getting in daze! I need a safer replacement for this stupid medication! | F | 10 | 7 days 10mg | 11/21/2019 | 1 | Pet allergies | Rage, hate , crazy thoughts, strange erratic behavior. | M | 10 | 0 days Children’s | 1/4/2020 | 1 | allergies | Nasty, nasty, nasty! Gave this to my 10 year-old son for allergies (chronic sinus infections). I just started Clarinex myself 2 weeks ago, but before that nobody in our family or extended families have ever been on allergy medicine, so it's very new to me. I don't like the idea of my child being on medication like this every day. Anyway, we started the Zyrtec and within a couple days, our son turned into a nasty, combative, argumentative child. My ordinarily calm husband and myself were at our wits' ends with him and were ready to consider therapy. My husband wondered if it was the Zyrtec. Then I remembered that when my son was little (and his older sister also), I could not give them cold medicine because it would turn them into little monsters. I figured it was because they were sick. Anyway, I stopped the Zyrtec several days ago and WHAT A DIFFERENCE! Overnight, he changed back into the son I know and love. The doctor called in a prescription for a nasal spray this afternoon | I notice that a large percentage of children with this same reaction are male. I wonder what the correlation is, if there is one. | M | 10 | 1 weeks | 4/15/2006 | 1 | seasonal allergies | My son was given both zyrtec and flonase for seasonal allergies. It seemed to work ok when we first began them. I was not faithful in giving them all the times and usually gave them only when seasonal allergies were bad. We have finally figured out that both of these medications were effecting him negatively so we took him off them immediately. Symptoms were: stomach pain, headache, times of panic, heavy headedness, severe anxiety, insomnia, loss of appetite, weight loss and probably more that I am forgetting to list. Think carefully before giving this medication to your child. My son has been off the meds for 5 days and is feeling SO MUCH BETTER! | M | 10 | 11 months 10mg 1X day | 10/3/2011 | 1 | My 10 yr old son, for allergies | My son is on a number of meds to start with, including Prozac and Lithium, however, it is far too coincidental that 10 days into using Zyrtec daily, he went from stable and happy, to a wreck...depressed, anxious, panicky, angry, tantrums, nightmares, stomachaches...and the last two days, hearing voices. I remembered this time last year when Clartitin also had a bad effect in him, so my first thought this morning was to search...and found this forum (thank goodness!) No more Zyrtec for him! I think some kids are just especially vulnerable to chemically triggered mood changes, but a kid with a mood disorder already diagnosed might be even more at risk. I would urge all parents to monitor their kids behavior if starting this med, previous disorder or not. | M | 10 | 10 days 10 mg 1X day | 4/7/2011 | 1 | allergies | My daughter (almost 10) has been taking since March. She has become very depressed, irritable, goes into rages that last up to 2 hours. Her pupils become dilated and its like she is not even there. So bad we had to call police on her! | F | 10 | 1X day | 5/4/2011 | 5 | year round allergies, pet allergies | none | Wow...what a great website! I've been reading others comments and simply can't believe what I'm reading!! My son has been taking zytec for about 3 years now, and we have never, never experienced any of the horrible side effects some have described. At the risk of sounding like "one of those parents", my son is a great student, straight A's, no behavioral problems, just an all around well-adjusted kid who is a good friend and leader in his class. Good luck to all you parents who've had bad experiences, but we love and will continue to use zyrtec when it goes OTC. | M | 11 | 3 years | 1/23/2008 | 5 | Asthma, respiratory issues | My 11 year old takes this medication. No side effects at all when she takes it at night. Some slight drowsiness when she takes it in the morning. | This medication has been a blessing. My daughter used to miss school all the time becuase of respiratory issues. Her asthma was getting worse and lasted longer. Our doctor first suggested inhaled steroids but we tried zyrtec first and it has been a miracle for her. NO asthma for 6 months so far. This is unheard of for us. I have seen no negative behavior changes. If anything her behavior, mood, and concentration have improved significantly. I can only attribute that to the better health this drug has given her. | F | 11 | 6 months | 12/17/2009 |
