| 2 | Moodiness not sleeping well my friend asked about what allergy medication she was taking and now I think I have found the reason for her outburst. I am still going to have her see a therapist just in case it is so something else. I think the medicine has a lot to do with her outburst though and her lack of sleep | F | 11 | 1 years 30mg | 7/3/2015 | 1 | Allergies | My 11 year old son's usually agreeable personality dramatically changed. He slept until 8:30 am when he always gets up around 7am and then proceeded to yell and be disagreeable all day long. He even called me names he has never dared use before! When I read about the medication and realized it might be a factor talked to him about why he was behaving the way he was. He apologized and said the medication made him feel "out of control" when he got angry. | Unbelievable that a pediatrician had prescribed this for mild allergy symptoms! I hate to think of all the children out there who are taking this - this should be taken off the market in my opinion. | M | 11 | 1 days 1X day | 6/27/2014 | 1 | 11 year old son taking it for hives | severe irritability, depression, and anger | the symptoms were pronounced when on the drug and went away shortly after stopping the drug. we had been advised to use zyrtec preventatively and on an ongoing basis. given our son's reaction, this would doom him to a life of mental health problems. he is fine since we stopped it. we will use benadryl in the future for short term relief. | M | 11 | 10 days | 8/13/2009 | 1 | Allergies | Anxiety, depression, rage, dark thoughts, insecurity | I which I could give a negative rating for ZYRTEC. Zyrtec turned my daughter into a different child. Over the past three months she has changed from a typical 11 year old (with occasional drama but always good natured, kind and reasonable) into a girl that has intense irrational meltdowns several times a day. I am very sad to say that we initial brushed her behavior off as typical preteen drama but the intensity of her outburst made me believe that something else was going on with her. I finally made the connection this morning and began researching the side effects. I called my child's doctor and sadly they have never heard of any side effects like this from Zyrtec - wow- so scary! I encourage anyone who has had side-effects to log them here. I usually do not do this, but I am so scared for the kids that are taking this drug. If parents do not make the link between ZYRTEC and behavior these children could easily and unnecessarily get diagnosed with a mental health condition. | F | 11 | 3 months 1X day | 5/31/2013 | 5 | Seasonal Allergies | None noticed. Doc suggested daughter take this at night as some experience drowsiness. She does take it then, but have not seen a 'drowsiness' side effect. | This drug has been a gift to my daughter. Summer of 2009 (pre-allergy-diagnosis) was a nightmare. Daughter coughed all summer long...many trips to doc. End of summer finally diagnosed with allergies. Put on Zyrtec and a nose spray and we finally had our 'normal' daughter back...including sleeping better as she wasn't coughing all of the time. Takes it only during allergy season...stops at first freeze and starts again about mid-March. Summer of 2010 has been GREAT for her! | F | 12 | 1.5 years 10 MG 1X day | 8/20/2010 | 5 | ADHD | During the time of my journey through life, I had noticed that every time I played video games I would only go for body shots, but after taking Zyrtec, all I would want to get were HEAD SHOTS. I felt extremely angered by normal everyday noobs. After I started taking Zyrtec I wanted to PWN them like they have never been Pwned before, and I still have ADHD!!? whats up wit dat? Head Explosions Public Urination Every time I get a gun in my hand, it automatically points to someone's head. Uncontrollable peanut butter texture of my stool Speaking Ebonics Black Rage The plague | Zyrtec gave me AIDS. | M | 12 | 20 days 10mg 2X day | 6/30/2010 | 3 | Allergies - seasonal and pet | My son (now 12) has been taking zyrtec for about 4 years. It completely took care of all of his allergies; however, he has become increasingly angry and has temper tantrums...yes, at the age of 12!!! Not a pretty sight and also happens at school. He is a gifted child and has never had any behavioral problems until being on zyrtec. We never experienced this before and I am so glad I found this site because after reading all of the comments, I see a definite common demoninator among children who take zyrtec and that is anger. I must find something else immediately. | I wish I had known this BEFORE as it will be very difficlt to find a medication that will do all that zyrtec has done WITHOUT causing anger and violent behavior. | M | 12 | 4 years | 6/1/2005 | 2 | Hay Fever | frequent nervousness, trouble sleeping. | Not very good | M | 12 | 3 years 1X day | 4/30/2012 | 2 | Allergies and Asthma | My 12 year-old daughter has been taking zyrtec off and on for 6 months. She is a lovable, creative kid who gets along well with others. She was having some trouble with her asthma this summer and having a feeling that she was not getting enough air in. We've had two episodes this summer where her anxiety was so bad she was in an uncontrolable state of crying and fear. She felt like she was going to die and wanted to go to the hospital. She's experienced feelings of despair and anxiety that I can't help her come out of. She's become constantly afraid and worried about dying. Not her usual Shirley Temple self. I'm taking her off zyrtec forever. I think it has really produced all of her anxiety. Many thanks to all who have posted their stories. | F | 12 | 6 months | 8/22/2009 | 1 | seasonal allergies | heart racing, trouble breathing, severe anxiety, irrational thoughts, severe depression, low self esteem... | This is by far the most horrible drug EVER created!I'm so sad that I'm just now putting two and two together!My son has seasonal allergies so I've given him zyrtec for 2 weeks now. He approached me yesterday and told me that he needed to talk to me about something.I could see the concern in his eyes. He told me that he was afraid of me not loving him anymore if he told me these things. He told me that he was having very bad thoughts of hurting his family.I was needless to say shocked considering that he's the sweetest kid I know. He had also been complaining for several days about his "heart" hurting, and shallow breathing. he kept describing this weird feeling in his head,described it as a feeling of intense pressure. I spent the whole day with him trying to put possitive thoughts in his head. yesterday his allergies were bad,and just as I was about to reach for the zyrtec a little light went off. I looked up this drug and it's possible side effects. I'm so blessed that I found this website.I'm also so angry that so many of you had similar stories! The sad thing about this drug is that it is highly reccommended by so many Doctors!I would NEVER reccommend this to anyone! | M | 12 | 2 weeks | 9/5/2009 | 1 | Seasonal Allergies | Zyrtec caused my 12 year old son to be tired, drowsy, and drugged out and it didn't work very well. | For years I have been giving my 12 year old son lots of different allergy drugs, including Claritin, Tylenol, Zyrtec and others. None of them really worked and they all made him very tired and drugged out. Recently, I saw Dr Hansen on our morning news show here in Arizona as he was talking about a natural allergy product named Flavinox and explaining how it works and it really made sense to me. I drove over to his Scottsdale office that morning to get a bottle and went directly to my sons school to start him on the capsules. When he came home from school about 3 hours later he was like a different person than when he left that morning. I could see it in his face and eyes. He was feeling 100% better and he told me about an hour after he took the capsule he could feel the difference and he kept feeling better as the day went on. Since then I have been giving him about 3 capsules a day and he's a baseball player so sometimes before a game I give him an extra one and I am truly amazed a | M | 12 | 1 years | 3/7/2009 | 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 | 5/18/2009 | 1 | allergies | After only taking this medicine once, I expericed stomach pains,sore throat, runny nose, pressure build-up in my nose,and inability to sleep through out the night. | F | 12 | 1 days 10mg 1X day | 5/19/2010 | 1 | Allergies | Depression, temper-tantrums, mood swings. | This is like a body snatcher. I've been fine, then after the zyrtec, I want to kill myself. NO ONE TAKE THIS MEDICINE! | M | 12 | 3 months | 3/14/2008 | 4 | allergies | My 13 year old son took this medication. After about 5 days on Zyrtec we began to notice changes to his behavior, attitude, personality. Did not immediately relate it to the medication. Attitude change at school with teachers so extreme that a teacher notified me because my son "was not himself". I began to monitor and investigate. The withdrawal from wanting to be with peers and being content with just playing video games was not acceptable to us and we set down very strict rules to try to determine the cause of the changes. I went online and began to investigate the Zyrtec side effects. After reading similar accounts, I immediately stopped the meds. Within 5 - 7 days, he was back to the young person we are used to living with and the teachers agreed. I work in a mental health field and teaching youth and I constantly think about what are actually the students problems or conditions vs. what may be the side effects of meds they are taking. | The extreme emotional and mental health side effects were not worth the benefits of managing the allergy symptoms with this medication. | M | 13 | 5 weeks | 7/11/2007 | 4 | dermatographia | some drowsyness at first, but i took it before bed and eventually i became immune to its soporific content, and very mild depression and mood swings, but they have faded. now im hearing that zyrtec can cause short term memory loss? this is just a rumor, has anyone else heard this? | ive had dermatographia for a year, and zyrtec extremely reduced the histamine reaction and the itchyness, although it didnt cure the hot, red marks i get. if anyone has any suggestion to reduce the effects of dermatographia, please email me | F | 13 | 1 years | 1/19/2005 | 2 | allergies | I still had itcy eyes, and was sneezing after taking it. I take it off and on. When I do take zyrtec, after a few days, I get bloody noses. | F | 13 | 2 days | 5/14/2005 | 2 | allergies | none | have not noticed any changes in allergies | M | 13 | | 12/25/2000 | 1 | my son's allergies | My 13 year old son started taking this medicine a little over a month ago and he has had mood swings and violent temper tantrums. I am not even sure if it helped his allergies. I am stopping this medicine immediately!! He is gifted and generous kid when not on this nedicine. Now he is a angry, negative brat. Hopefully, taking him off this medicine he will mellow out again and not be so mean and hurtful to all of us. I am so glad that I found this site!!! I wonder why Zrytec won't mention these side effects????!!! | I have already let my son's Doctor know about this terrible reaction to this!! I will never reccomd this medicine. I am also going to contact Zyrtec regarding this side effect. No one needs to be this miserable and unhappy and angry! | M | 13 | 32 days | 10/5/2005 | 1 | All year round allergies | MIGRAINES! Anyone who's had them will tell you, NOT PLEASANT! The worst pain I have EVER experienced. P.S. To people who have, if you get a migraine, the minute you see the blind spot, take excederin migraine. WORKS soooo well. | I had gotten a migraine ONCE before I started Zyrtec, about 2 years back. Then I started taking Zyrtec. My whole family called it "The Miracle Drug" I thought, "I'll never ever have to suffer again! This is so great!" Then about 3 months in, I got a migraine. We thought, oh, well I've had one before, it's just a rare thing. Then about 3 months later, another! Then approx. 3 months later, AGAIN! Then I stopped taking it for finacial reasons, but saved ONE pill. We were going to a party that was outside, and so I took it. BOOM! Migraine. I KNOW that's what caused them. It's been about, oh, 4-5 months with no migraines. I would NOT take this medicine. FOR ANYTHING. | F | 13 | 1 years | 2/7/2008 |
