 5  Allergies and sinusitis My daughter is taking it since a month ago and we have not noticed any wrong side effects, we are giving her the mexican equivalent (called Virlix). I am assuming that the problem of the side effects others are expiriencing could be residing in the formula of Zyrtec. She has been previously on Clarytin, Benadryl, etc. and none has helped her as this one... Maybe if you could get the Mexican variation of the same drug you could give a try, there is no need a prescription to buy it there... best wishes to you all. F 3 1 months

 5  Allergies If take full dose (5 mg) he gets very hyper..if takes 2.5 mg in am and 2.5 in pm have had no problems Please note I see a majority of these reviews show 1 x daily..wonder they are taking the 24 hr or just the 12 hr dosage...this can make a difference as one has psuedophedrine in it for adults..as for children..if I see a product working but side effects (if not dangerous) then I try to break the dose down so they are metabolizing a little at the time not a full dose.. remarkable how well it works when do this M 3 2 years

 4  rhinitis and other allergy symptoms We are curious if this has affected his growth. He was 85% (height/weight) at birth and is now 25% (height/weight). My wife and I are both quite tall. She is 5'9" and I am 6'3". Just thought I would post this in case someone else sees the same thing. Symptoms have subsided fairly well. Without this our son required using the nasal tool 2-4 times per night. Now, more than half the time we don't even use it once. We only give about 1/4 of the recommended dose for his size and it seems to help alot. We cut the pills. M 3 1 years

 3  Seasonal Allergies I started giving my 3 yr. old Zyrtec 8 days ago. It seems to be helping the stuffy nose and itchy eyes. Two days after starting the meds., She started having accidents. She has been fully potty-trained for a whole year- no accidents. Now she has 3-4 a day. She tells me she just can't tell when she has to go anymore. F 3 8 days

 2  Allergies Mood changes, aggression, social anxiety, clingyness My 3 year old son has been taking this medication for over a year. We hadn't connected the behavior changes with the medication until it was suggested that the issues were not necessarily just the terrible twos. He has been off of it for 4 days and I am already starting to notice a difference. He is less clingy, more social, and generally less aggressive with his sister. I am not saying not to take it, but for us, the side effects clearly over shadow the possible benefits. Planning on stocking up on benedryl! M 3 1 years

 2  Allergies/Asthma Tried this drug with my 3 year old daughter to help control her asthma attacks (well, to control her allergies which her doctor thought were aggravating her asthma). She was on it for two days and I immediately saw fatigue and very aggressive moodiness. She gets very upset over the smallest things where she is ordinarily very laid back and easy going. We're taking her off after reading this site. F 3 2 days

 2  allergies My 3 yr old became a different person, yelling, biting, spitting, throwing things, and agitated by the 2nd day. Called doctor and they weren't even surprised! Suggested I try Claritin, but said it might do the same thing. Zyrtec cleared up the allergies quickly, but, I'd rather have my runny nosed angel than the clean faced, unpredictable stranger on Zyrtec. F 3 2 days

 1  Allergies My almost 3 yr old daughter has been taking Zyrtec for about 3.5 months. We were told to take it (by a Ear,Nose,Throat Specialist no less) to "dry her head up" after a severe earache that would not go away. It worked, no more severe drainage for DAYS. HOWEVER: Over these last few months my happy child has been aggressive, short tempered, occasional catatonic like stares, prone to tantrums and will fall apart at the drop of a hat, as if possessed / bi-polar ! She also would say occasionally that her tummy hurt, her "pookie" (vaginal area) itched/hurt and she was drinking tons of water, had a few headaches and sore throats along with runny stools constantly. We NEVER connected the two (med and behavior) due to her being 2.5 , a new baby brother and being in play school. We blamed everything else. My husband found this site and as of this morning she is OFF Zyrtec and I hope by daughter will be back soon. Thank you !!!! The doctors need to tell parents the REAL side effects and let the parents choose if the cure is worth the poison. If we had been informed of the TRUE side effects, not what the label says, we NEVER would have put her on the drug ! F 3 3 months

 1  Eczema, Asthma Mood swings, temper tantrums, violent outbursts, crying about little things, irritable. My son has suffered from eczema and asthma since he was born. He has been diagnosed and misdiagnosed many times. He was prescribed many different things from steroid creams to antihistamines of all sorts. Nothing has worked in the medical world, but zyrtec was the biggest mistake of all. My sweet little boy turns into a demon in front of my eyes and at a drop of a hat. All children have there bad days but let me tell you that this poison makes our kids into different children. My heart breaks that I had no warning from his doctor or on the label. Its not fair that these poor babies suffer not only with the aliment they are cursed with, but with extra symptoms caused by something meant to help them. They are little people with no voice. These drug companies should be ashamed!! Parents if you are here its to late you have given your kid this drug. Please stop ASAP! M 3 2 months

 1  allergies severe stuttering and vaginal irration my daughter began this med when she was 2 years old. within 1 month she began to STUTTER. she has been on this med about 1 1/2 years. we have spent thousands of $ on speech therapy and it has not helped. the stuttering has become worse over time. the zyrtec dose was upped over time due to her weight gain. the more zyrtec, the more she could not complete a single sentence. i took her off of it 1 week ago and have seen mild improvement and severe withdrawl (itching, crying, sleeplessness, depression). she has also experienced vaginal irration for about 1 year, so much that i took her to a gyn 2 weeks ago and had her tested for ANYTHING and everything. all of her tests came back normal. i began to suspect zyrtec after praying about it. i am now convinced that it is the medication.. anyone else experience this?

 1  allergy (trees, mold) Aggression, temper tantrums, sleepiness, but also waking at night and unable to settle back down without help. We thought the aggression and tantrums this past summer were just age-related, but in the fall our son started hitting/kicking kids at preschool. We took him off the Zyrtec after we had a frost and his allergy symptoms subsided, and when the Zyrtec stopped, so did the negative reports from preschool. We also noticed a significant drop in tantrums at home. But then the weather warmed back up and the mold count shot up and his allergy symptoms came back. Gave our son a Zyrtec dose yesterday before school (the first time in 3 weeks), and when I picked him up from school, was told he had grabbed a girl by the hair and dragged her across the playground. This is a kid who hasn't shown aggressive behavior since we stopped the Zyrtec. Talked to his teacher about a possible connection, and she said that she took herself off Zyrtec because it made her feel jittery and nervous. Our son's allergy symptoms are better when he's on Zyrtec, but I am going to stop giving it to him. As I read about s M 3 8 weeks

 1  eczema itching and allergies Unbelievable change in behavior for 6 weeks now. And it finally hit me that all of this started with the Zyrtec. We have been miserable with tantrums, aggression, problems playing with the other children in school and he seemed to not hear anything said to him. We will go off immediately and hope for changes. I think that doctors should inform patients to stop if these mood changes are noticed. You have all given me hope. M 3 6 weeks

 1  Allergies We gave Zyrtec to our 3 year and she turned into a little monster, kicking and hitting. After about a month a light went on in my head, oh my god it's been about a month since we started her on Zyrtec. Thats when we looked on the net and found this site, after seeing the same stories we took her off of it and within a couple days she was a little angel again.. There should be a HUGE warning label on this stuff for children. When my daughters cute smiles and funny looks came back it brought tears to my eyes.. I would not give this to my children again if was the only thing on earth to stop their runny noses. F 3 1 months

 1  allergies My daughter started taking this for ecezma and allergies. She also has ashtma. I took her off the singulair and pulmicort too. She was a monster! My son who is 6 was on all these as well. I thought I was a bad mother and had mentally ill children.Then one day it occured to me to research these meds and was shocked to find out it was not just us. My kids are finally returning to normal.I worry about their ashtma but I couldn't take another day of it.I have tried to take my daughter off the zrtec before and the itching is unreal for her already bad eczema.Last night was her last dose!We will have to make it this time and get rid of it. What is wrong with these doctors giving this garbage? They should have to live with the kids that take it! F 3 9 months
