 1  Seasonal allergies Irritable, moody, night terrors. My kid never had issues sleeping and was generally a very happy child. The only thing I changed was I switched from Claratin to Zyrtec and he changed. Moods and all. I did not connect that to Zyrtec till I noticed that he began having night terrors. I took him off 24 hours ago. Let's hope things get better. M 5 4 days

 2  Allergies My 7 year old took Zyrtec for a year for seasonal allergies. It seemed to work wonders! His allergy symptoms disappeared. Not long after starting the medication, he complained daily of horrible abdominal pain. We saw countless doctors, looking for answers. Blood test, after blood test, X-rays, CT scans, upper and lower scopes, food sensitivity tests, we even saw an urologist! None of the above gave us any answers! We were left with a 7 year old with what they called "unexplained chronic abdominal pain"! I felt so helpless! We decided to stop the Zyrtec temporarily, his belly pain completely disappeared! I was shocked! I came across this site and could not believe how many others have experienced the same symptoms! This drug has caused so much you left for my family, something needs to be done! In the year he was on the medication he also experienced itchy skin, headaches and sore throat! M 7 1 years

 1  Seasonal allergies Extreme sadness, bouts of anger, inability to fall asleep. I cannot believe I am just now making the connection between my sons sudden mood and behavior changes and Zyrtec. He told me tonight that he is scared he is going to be sad forever and he can’t figure out why. He cries even when he is doing the things that he normally loves. I can’t wait until this med is out of his system completely. M 9 4 months

 1  5 year old son Back in Nov of 2018 my 5 year old son was prescribed zyrtec on an as needed basis to help with seasonal allergies. We would give him a pill as needed either in the am or before bed. Between 2018 and the summer of 2019 we really hadn't given him much of the medication but from time to time we were called by the tk teacher stating our son had a bad day; couldn't control his emotions. My husband did not think much of it. When he started kindergarten in 2019 we started giving him a pill here and there to help w/ his allergies. Again, we started getting calls from the school that our son was in a blind rage. Unable to control himself. Lashing out at the smallest of things. Displaying OCD traits due to high anxiety (washing his hands until they were red and cracked). One night he spoke to my husband and I telling us he didn't like his face, or hair or himself. It was a very sad moment coming from a child that normally was the happiest kid ever. We felt his pain and were concerned that Please, don't let your child take Zyrtec. My husband and I spent hours with a counselor questioning our parenting skills. We punished or took away things he loved as a consequence for his bad behavior, which wasn't his faught. We had secured an appointment for our son with a counselor because we felt there was something deeper that we couldn't help him through. Truth is it was the zyrtec as in so many other cases. It's very sad to think doctors think it's ok for this to be prescribed to children. It crosses over the blood brain barrier and creates so may of these side affects. I never post on any sights but feel this experience is so important and how badly medicine affects our children others know about it. Find another alternative...... F 5 15 times

 2  Allergies I put my 2 year old on this medication and the next days saw a mood difference. He was constantly doing something to get in trouble, moody and aggressive. I was very displeased. I was made to believe it was safe for children but I’ll take the allergies over aggression. I wanted to make sure it was the medication so I tried it once more and the next day after giving him the medication at night, again he was moody and aggressive and not himself. M 2 7 days

 1  seasonal allergies tantrums, angry, aggressive, noncompliant, mean This made my 3 and a half year old son mean, angry, aggressive and frustrated. He didn't want to go to school. He was hitting me and his sister. He was not himself. I didn't recognize him. Thank God I found these posts and stopped this drug after week. I would like this to be listed as an official side effect with FDA. If anyone knows how to go about petitioning that side effects be added please contact me. This drug took a big toll on my relationship with my son and I am upset I was not warned of its effects. M 3.5 1 weeks

 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

 1  Allergies asthma I had occasionally given my son Zyrtec or generic cetrizine 5mg during allergy season, but when the doctors prescribed a 10mg dose daily is when I finally put 2 and 2 together and the side effects really got bad. Each day of that week he got progressively worse with crazy out of control tantrums. He’s always been on the emotional side so I’ve seen a fit but these were awful, kicking, thrashing, head banging, hitting, like blind with rage, totally not reachable. He literally could not control it even when I could get him to hear me. It was so so scary. I can only imagine how scary it must’ve been for him. M 5 5 days

 1  My son's seasonal allergies My son, age 7, has been experiencing extreme anxiety recently, including feelings of paranoia, stress and worry. It's been frightening! He's been taking Zyrtec for about a month and although it helped his allergies, it's changed his personality. We have stopped Zyrtec and are hoping he is back to his happy self soon. Please remember to contact the FDA with any drug side effects. They can be reached at www.fda.gov/medwatch or 1-800-FDA-1088. The makers of Zyrtec need to know the harm that their product can cause.
