 1  sinusitis My 8-year-old daughter was given zyrtec for 2 weeks to treat sinusitis first and then sinus infection. She became moody, started displaying extreme anger and irritability. It culminated into a terrible, violent temper tantrum on day 12, in which she was screaming, scratching her face and kicking everything around her. This is totally uncharacteristic for her. As a toddler she threw a few tantrums, but never as violent as this. It didn't occur to me it was the medication until then. She's now off of it for 3 days. Lingering effects on her mood continue but to a lesser degree. I had been reading on this site about similar effects on adults and children who took Claritin and other loratadine brands. She had taken Claritin for a week two months back, for similar sinus-related complains. After the violent tantrum, I checked for Zyrtec effects, and was surprised to find the same. Our pediatrician never warned us of such side effects. All my research on the web didn't bring up anything like that, until I FOUND THIS SITE. It's the only place where this information is available. THANKS. F 9 12 days

 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

 3  asthma Not exactly sure as my 11 month old is taking this. I think he has become more aggressive, but this could be attributed to him becoming a toddler. M 1 4 days

 1  allergies/asthma My son who is 2 1/2 had MAJOR TEMPER TANTRUMS and VIOLENT OUTBURSTS where he would hit and kick...not only hurting people but himself...he would throw things and kick and SCREAM!!! Almost like he had no control of his impulses and exaggerated temper. This was not like him at all. Stopped the medication and my nice son returned. Sure he had a tantrum here and there but they were normal toddler ones...not scarry ones. I was not aware until coming to this website that this can be a side effect. His Dr. prescribed it for supplemental allergy fighter as he also takes Singulair and Pulmicort for his asthma. I would rather him be congested and cough than have these fits. I think we will stick to Claritin. M 2.5 1 weeks

 2  hives My 9-year-old daughter, who is normally the life of the party, now seems depressed. She's definitely not herself. She says she just doesn't feel right, her throat feels weird, as does her stomach. But the depression is what made me go on the computer tonight to find out more about this medication. She's been on it for 3 to 4 weeks for hives. I think she would rather have hives than feel so sad and insecure. F 9 3 weeks

 1  9 year old daughter has allergies My daughter's mood changed drastically. She was irritable and angry to the point we thought she was depressed. She also had a rash of white bumps around her eye and cheek. After we took her off zyrtec her normal personality came right back and the bumps went away. This medicine made our daughter miserable. I think it is dangerous. F 9 4 months

 1  severe allergies behavioral problems, emotional numbness, could not sleep, lots of temper tantrums, did not seem to help with allergies after a certain time of day, upped the dosage and he had more unusual behaviors, speech delayed. This medicine almost ruined my child!!! For a long time I thought my child was autistic. I finally got him an appointment to get him evaluated because he more or less fit the mold of an autistic child. After a year of bad results with zyrtec, I took him off of it and within days he was a different child. He stopped all his irrational, abnormal behaviors, started sleeping and most importantly started talking and responding to life. I thought I was helping him because of his severe allergies, but instead zyrtec robbed him of a year of his life. M 4 1 years

 1  Son was taking it for allergies My son (now 6) had serious behavioral problems to the point of being suspended 15 times from kindergarten. He had always been on zyrtec since he was a baby and had behavioral problems since then also. Stopped the Zyrtec and have not had a problem since. It had gotten to the point we had him seeing a therapist, did behavioral testing etc. Then I stopped the Zyrtec and he doesn't have the problems anymore. He had a VERY bad temper, would not listen to anyone, very defiant, very hyper. I stopped the Zyrtec and there was an almost immediate change in his behavior, back to a normal rational 6 year old. M 6 4 years
