| 1 | Allergies | dry, sore throat; coughing; irritability. | My son was prescribed Zyrtec for "allergies", for one month he'd had a nighttime cough and his tonsils were enlarged. It did not help my son's sore throat and coughing, instead I believe it aggravated his throat further. His behavior changed for the worse, biting me and grinding his teeth in anger, which could be because he wasn't feeling well but after reading comments from other parents of young children, I wonder if the Zyrtec caused the change. I've taken him off the med, and he is sleeping much better and is acting better. | M | 3 | 1 months | 12/10/2006 | 1 | allergies | My child went immediately from a happy, sweet child to a wild raging monster. She has never been one to throw temper tantrums and she was nearly unrecognizable as the same child. She seemed distraught and unable to control her emotions. | I would not recommend this for anyone who has experienced sensitivity to antihistamines. | F | 3 | 4 days | 3/1/2005 | 1 | Daughter Eczema & Food Allergies | rash all over body, night terrors, relentless whining, hitting, stubborn fits, crying spells over small things, would not play well with others, circle around eyes, fear issues, and became very clingy | My daughter has extreme Eczema in the creases of her body (inner elbow, back of knees) which is the worse during the winter months. At first it did a great job of taking her itching away and I was relieved. Her skin went from scabs to normal. Then it came back with a vengeance. I gave her Zyrtec again but, this time it was as if she had become immune. I had to increase the amount given to her to work. She became a totally different little girl. The thing that was most concerning was the night terror which is as is half awake and someone was killing her. Screaming, kicking, crying but not really awake. Then she started hitting her little brother all the time and would not share at all. She use to adore him and pamper him. Instead of making it better she slowly got itchy bumps all over her body. The hard part is watching her itch all over now due the prolonged use of Zyrtec. I am taking her off immediately and looking at diet options instead like Gluten free diets. I am glad t | F | 3 | 6 months | 10/15/2008 | 1 | Allergies | My daughter was given this for her allergies and congestion. Her behavior was "off the charts" crazy. I became so afraid of the way she was acting last night that I almost called the after hours emergency line. She was very jittery and thirsty but mostly just very strange, agressive, angry behavior. She was throwing stuff, yelling, screaming, mumbling strange things to herself. It was like she suddenly became another child. It was very scary. I couldn't get her to go to sleep despite the fact that she had skipped her nap and she was exhausted. She is still in bed this morning after finally falling asleep around midnight. Hoping she will be back to herself when she gets up... we will certainly not be using this again for her allergies. That was horrifying. | I personally take Zyrtec for my allergies and it works great for me. Little or no side effects and really drys up my congestion. I cannot believe the difference in side effects for children taking this medication. I have two other friends who also give this to their children regulary (and have done so for years) and do not experience these same effects. So I personally think that it can vary quite a bit from child to child. I personally will not give it to my daughter again. | F | 3 | 1 days | 12/21/2006 | 1 | Extreme nightmares, stomach ache, tantrums and not sleeping. | My son was taking Zytec off and on since 6 months of age. He is 3 now. He is a wonderful child and sleeper. The last 2 weeks on Zyrtec - 1/2 dose has been hell. He saw a tv picture of a fire one day and hasn't been the same sense. He has been off of the poison for 5 days now and he is STILL having nighmares. This drug is terrible and we were not warned either. What to do next with his allergies???? | M | 3 | 14 days | 7/9/2006 | 1 | allergies | Allergy symtoms got better for awhile, then had to switch my son to singulair because he wasn't responding to zyrtec anymore. He took it from age 20 months until 3 years old. He is now diagnosed with PDD. A developmental delay - could it be related? | His problems started around the time we started the zyrtec. It makes me so angry that I wasn't informed about the potential side effects. My child is now delayed in speech and social skills. He is been off all allergy meds for 1 week and is much better, talking more and using his imagination.DON'T GIVE THIS TO YOUR KIDS! | M | 3 | 16 months | 6/6/2006 | 1 | seasonal allergies | Unusual irritability, sleeplessness, fatigue, moodiness, tantrums | My 3 year old son started taking zyrtec liquid two weeks ago. After 1 week he became incredibly moody, was having trouble paying attention in school, would not nap despite being very fatigued. He also became so disruptive in class that his teachers called a parent-teacher conference with us because they were so concerned about him being "not himself." This is a child who is even-tempered and easygoing 99% of the time. In the span of a week he would dissolve in tears and tantrums throughout the day at the drop of a hat! We stopped zyrtec 36 hours ago. My sweet little boy is back. His teachers said he had a "great day today", took a long nap, paid attention in circle time, and fell asleep easily (while singing happily) for the first time in a week. Zyretc should include a strong warning regarding possible marked physical and psychological effects in children! If anyone knows how/where to report this, please contact me. I am calling my son's doctor in the m | M | 3 | 14 days | 4/20/2006 | 1 | Allergies | Irritability, aggressive behavior, loss of appetite. After a couple of days on the drug, we had to take our son in for extreme drunk-like behavior. He walked around with a limp all day and was slurring his speech. At the time, I was thinking the worst, like a brain tumor or something. At the recommendation of his pediatrician, we took him off it for two days then started him back on it at half the original dose. He was walking and talking better, but we still definitely noticed increased irritability and moodiness, as well as having problems getting along with his friends, and he would cry at the drop of a hat. I felt like I was always disciplining him over his behavior, when all along it was the effects of this drug. Then we took him off it completely for about 3 days, and he got a rash all over his body, but his temperment was back to normal--we got our sweet, calm son back! | DO NOT PUT YOUR CHILDREN ON THIS DRUG!!! | M | 3 | 1 days | 3/5/2007 | 1 | seasonal allergies | My now 3 year old son has been on and off Zyrtec for over a year. He first began taking Zyrtec at age 2. At the time we thought that he was going through the terrible two's. Hitting, biting, temper-tantrums. Just an over all inability to control his emotions. We took him off for 2 months over the summer, we noticed how much more in control he was. We just attributed this to that fact that we was a year older and more mature. 6 days ago we started him back on the Zyrtec and within 24 hours we saw a total deterioration of his mood and behavior. He was crying uncontrollably, throwing temper-tantrums, unable to nap, and back to hitting and biting. | M | 3 | 1 days | 9/24/2005 | 1 | allergies | severe stuttering | I am a Speech Pathologist working with young children. I have a student who had sudden onset of severe stuttering. I tried every method of therapy with no real change. I met with parents and they noted that they started Zyrtec around time of stuttering onset. They took him off it and stuttering was GONE, completely GONE. The family did a couple trials and we are all convinced it was the medication. | M | 3 | 6 months 1X day | 4/12/2012 | 1 | allergies | My 3 year old daughter had nightmares, stopped napping even though she hadn't slept well at night, and tantrums as soon as she started the Target-brand generic of Zyrtec. She is normally a very even-keeled child, and I can't believe it took me 4 days to figure this one out! Will never give her this again... | F | 3 | 4 days 2.5 mL 1X day | 4/9/2011 | 1 | ragweed allergies | Pediatrician recommended to give our 3 year old son for his allergies. Finally, he slept through the night without coughing fits and congestion. However, this medication took my sweet-natured boy and turned him in to something unrecognizeable. Very naughty behavior, total defiance, hitting, throwing, lack of appetite, infrequent urination... Within 3 days of his first dose I realized what the cause of his behavioral changes were and immediately removed him from this medicine (and tossed the remainder in the trash). Very shortly thereafter he was once again my loving son. I sure hope that the makers of this drug read these observations and determine a fix. It's a real shame when something that is supposed to help you can change you in to something completely unrecognizeable. ps: called the pedicatrician's office and they were aware of the possible reactions and noted in his file that my son can not have this medication. | F | 3 | 3 days 1 tsp 1X day | 10/5/2010 | 1 | allergies | Daughter 3 1/2-- really scarry to see my outgoing child turn into a non expressive sad child! She hasn't taken this for some time, but each time I give it this reaction occurs. Same with singular. | F | 3 | 1/2 tsp 2X day | 4/12/2010 | 1 | possible allergies, skin issues | extreme behavioral disorder (3 yr old) "possessed" | I have the world's sweetest 3 year old... until we had him on Zyrtec for four days. He woke up last night at midnight with uncontrollable energy. He fought with us, looking at us like he'd never seen us before, thrashing about, crying wildly and screaming. After about an hour, he finally went to sleep. This morning he was an angel again, and the Zyrtec is going in the trash. DON'T BUY OR USE. | M | 3 | 4 days | 5/28/2009 | 1 | Seasonal Allegries | Behavior problems, severe stuttering | My 3 year old son started taking over the counter Zyrtec for his seasonal allegies. Within a week his speech was terrible. He had never had problems with his speech. He literally woke up one day and had a severe stuttering problem. We took him to a speech pathologist and she recommened therpy. I would give him Zyrtec just as needed. I noticed that he would be better some days, but other days he could hardly speak. One day while wasting time away I looked up Zyrtec and found other comments about behavior changes. I took him off Zyrtec and his speech has become normal again. | M | 3 | 1 months | 9/7/2008 | 1 | seasonal allergies | My 3 yr old son exhibited hyperactivity and tantrums while taking the recommended dose. I am throwing it away! | M | 3 | 2 days | 8/11/2008 | 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 | 5/3/2009 | 1 | allergies | My 3 year old daughter became a different person | She has always been a sweet, attentive, loving little girl then about a year ago she started having some real problems. She was irritable, irrational, stopped talking, regressed in her potty training, complained daily of stomach pain, and seemed to be on a different planet most of the time. At one point it got so bad we almost had her tested for Autism. We finally made the connection that her bad phases coincided exactly with allergy season and realized it was Zyrtec. I was so relieved to find this web site and see that many others have come to the same conclusion. Now that she is not taking it we have our little girl back. It is wonderful. They really need to put stronger warnings on Zyrtec. | F | 3 | 1 years | 3/22/2009 | 1 | Seasonal Allergies | My daughter is 3 and has been having uncontrollable rages and tantrums. She is typically very sensitive so the occasional tantrum is typical but these tantrums last all day and are frightening; with her throwing herself off furniture and onto the floor, screaming and scratching at herself and others. She is inconsolable. She will never take this medicine again. | F | 3 | 5 days 2.5 mg 1X day | 3/18/2016 | 1 | pet allergy / seasonal congestion | Irritability, moodiness, anger, aggression, appetite changes, sleep problems, personality change | Our son was taking zyrtec on and off as needed for over a year. We thought he was just a high-maintenance strong-willed child. It wasn't until he started taking it daily for a couple weeks straight that he became completely unbearable. We would have honestly sworn the devil had possession over our child, that's the best way I can describe his behavior. It wasn't until I found this site that it made me think it was the medicine causing it. I stopped giving it to him, and within a couple days, he was a completely different child. Much easier to manage, more agreeable, and overall happy. I thank whoever created this site, and just wanted to post our story, so maybe someone else who experiences the same thing can learn from our misery! We have since tried Claritin, and it causes the same symptoms. Now we are on Allegra, time will tell how that fares... | M | 3 | 1 years | 8/13/2009 |
