|4||allergies and hives||None that I was aware of at the time.||I stopped taking zyrtec about 1 week ago and have had horrible itching. I thought at first it was from a new detergent but switched back to the old with no relief. Now reading this site I think I am in withdrawl. However I have never taken anything that worked so well for my allergies. I did develop a ringing in my ears shortly after starting it and wonder it anyone else has had that as a side effect? It is not going away since I stopped but it hasn't been that long yet.||F||53||2 years ||10/28/2006||1||Allergies||Drowsy all day long, Lethargic, Headaches, sick, depressed, shaky at times, irregular heartbeat,||I could not figure out why i was feeling so tired and completely exhausted all day long. I was talking Zyrtec at night but in the morning it was impossible to wake up. Then all day long I would feel tired and depressed. After reading this website I immediatley stopped taking zyrtec. However since i was talking it for two months it felt like my body was going through withdrawl from it. I would feel sick and at night could not sleep at all. This drug is the most HORRIBLE drug on the market and I would not reccommend this product to my own worst enemy. This product can completely ruin your body mentally, physically, and emotionaly. I would rather suffer from allergies all day long. I give it 100 thumbs down||M||24||2 months ||10/27/2006||2||seasonal allergies||trouble sleeping during the day during regular naptime, sore/dry throat, stomachace,loss of appetite, nosebleeds||My 2 1/2 year old was on Zyrtec liquid at night for 1 month and had these side effects. Once we went off Zyrtec, the issues stopped. Not happy. Not happy at all.||M||2.5||30 days ||10/24/2006||1||allergies||hands and feet swellings body aches. SLEEPINESS. DEPRESSION. I think it is a horrible drug. I stopped for a three days and was feeling much better. ( I was trying to see if Zyrtec was the problem) I took one last night. Nightmares hands,feet, backache body aches are back. I am THROUGH with Zytrec. I can take the 12.5 mg meclinzine You can ask druggist for it OTC. I will take that when I need it for allergies. I have been on Zyrtec on and off for years, and now I know I am not crazy!!!!||HORRIBLE DRUG!!!!||F||65||6 years ||10/18/2006||2||Allergies||My son's behavior changed so dramatically that I was looking into him seeing a child pyschologist. I noticed that his violent and depressive mood swings coincided with his taking the medication. As soon as I took him off of it he was fine! I was so relieved to see that others had the same concern.||M||7||60 days ||10/16/2006||1||son's cold/allergies||Within an hour of giving our 20 month old 1/2 tsp Zyrtec as the doctor prescribed, our son woke up screaming desperately. For the next 3 hours, he could not be consoled, running around, trembling and screaming as though terrorized. Occasionally he would fall asleep for a short while, only to wake up screaming again. It was really painful to watch. We were about to take him to the emergency room, but the doctor on call said to wait a while longer. He has never ever behaved like this, and he had not eaten/done anything else different, so we know it was the drug. This drug should NEVER be prescribed to children!||M||1.5||1 days ||10/14/2006||5||Severe allergies||Makes me tired so take it at bed time. If take it in the morning it makes me too tired.||The best antihistimine period and I have taken them all! Works on dust, mold, pet dander especially and seasonal allergies. I just love it! I wish all medicines worked as well as zyrtec.||F||37||6 years ||10/10/2006||1||Seasonal Allergy||My 7 year old daughter become unable to focus, had trouble concentating in school, complained of headaches, became extremely unhappy, and experienced weight gain while on Zyrtec. And, thankfully within days of switching to Singular we are seeing "our daughter" back again.||The side effects are horrible!||F||7||45 days ||10/8/2006 ||1||Seasonal Allergy||My 7 year old daughter become unable to focus, had trouble concentating in school, complained of headaches, became extremely unhappy, and experienced weight gain while on Zyrtec. And, thankfully within days of switching to Singular we are seeing "our daughter" back again.||The side effects are horrible!||F||7||45 days ||10/8/2006 ||1||Hives/cough/runny nose/red eyes||Intense mood swings, aggressive behavior, loss of appetite, fearfulness, broken sleep, diarhea, and spitting up.||My 15 month old has been on it for 10 days now. He was a very calm, even-tempered child. Quick to laugh- an angel. He has become seemingly possessed. He changed overnight- he is now hitting, biting, yelling/screaming and crying, then laughing again. He is pinching, waking up screaming at night and inconsolable. He is fearful, even of things he loved before. He went from never missing a meal to barely eating. After it took me two hours to get him to bed tonight, with him screaming hysterically the entire time, I looked online to find potential side effects of zyrtec (which I did before I gave it to him in the first place but I didn't find anything then). I am so relieved to have found this site and see other parents experiencing the same problems with the drug. I feel so bad that I gave it to him! I will never give him zyrtec again, and I will be sure to tell everyone I know not to take it or give it to their children. Though the drug did relieve his hives and lessen the runny nose/red||F||24||10 days ||10/6/2006 ||1||allergies - heyfever||My 4 1/2 yo son was put on Zyrtec to help control his hayfever. He experienced heightened behavioral problems at preschool - including intense hyperactivity, distractibility and inability to attend. He also experienced stomach problems and had diarrhea every day while on Zyrtec - at first we thought the diarrhea was directly related to an antibiotic he had been put on for 7 days but now we know he was cramping due to Zyrtec.||I might add that my son's doctor mistakingly put him on 10 mg instead of the 5 mg he should have been taking, for his age group. I am taking my son off Zyrtec - all together - and will see if that helps him get back to being "him" at school. If so, we might try a dosage of 5 mg at a later point in time. But after reading the comments here, I'm even skeptical about that level dosage in kids. Last night was his first night off of it and he woke up, mid night, with violent stomach pains, cramping and intense diarrhea.||M||4||3 weeks ||10/4/2006||4||allergy to dogs||irritibility, agitation, uncontrolled crying and anger.||My son uses Zyrtec only when he is going to be around dogs for an extended period of time; maybe 1-2 times a month when visiting family. I was blaming the behavioral changes on him being tired, etc., but it was too much of a coincidence. It works great for his allergies, however, the side effects are not worth it.||M||2.5||2 days ||9/25/2006||3||Allergies / Asthma||Increase appetite, weight gain||my daugther is 3 1/2 years old and has been eating ALL day! she will not stop eating. She has only been on this for 2 weeks and her allergies seem ok right now - but can't believe the increased appetite.||F||3||14 days ||9/23/2006||5||headaches allergic rhinitis||none whatsoever!||Had chronic headaches for years. zyrtec has helped immensely, but and i am amazed by reading all of the side effects you have mentioned. i have none. zero. zilch. except of course, my head doesnt hurt.||M||3 months ||9/19/2006||1||pet and pollen allergies||I took it for nearly a year before realizing that my insomnia and depression were caused by Zyrtec. I went off Zyrtec simply to get the antihistamines out of my body so I could be tested for additional allergies, and my mood lifted tremendously. So, I really inadvertently discovered that Zyrtec was causing my depression. I am so angry no one told me about this when I started taking it. It would have saved me so much misery.||F||40||1 years ||9/8/2006||4||Seasonal Allergies||Drowsiness, increased appetite, and dry mouth are the main side effects I have experienced. I went from a 10 mg dose to a 5 mg dose to combat the drowsiness but still find myself experiencing insatiable hunger.||I rated it a "4" because it really does control my allergy symptoms, but my appetite has been over the top. I'm only going to take it when I wake up with severe allergy symptoms. I can't risk the possibility of extreme weight gain.||F||42||1 years ||9/6/2006||1||We are investigating the effects of Zyrtec on infants, children and teenagers.

My solution was always to take another dose. Before long I was not taking the Zyrtec for my allergies, but rather to prevent the itching. I was told by a counselor friend of mine that it sounded like I was experiencing withdrawal. I researched, found this site, and have read that others have experienced similar withdrawal symptoms. I quit taking Zyrtec cold turkey and am experiencing frequent fits of INTENSE itching all over my body. I'm told that this should last about two weeks. So far it's one of the worst things I've ever experienced. A typical itching episode lasts from 45 minutes to 2 hours (of nonstop scratching)! I then usually get 30 minutes to an hour of no itching before it starts back up.||I gave a rating of 2 because I'm not satisfied with the withdrawal symptoms. However, when I first began taking Zyrtec, it relieved my sinus and throat allergies wonderfully. But all the allergy relief in the world is not worth what I'm going through. I would stay far, far away from Zyrtec.||M||30||3 years ||9/3/2006 ||5||general hay fever||Dry Eyes and Nostrils. Minimal side effects with a 5 mg dose. Significantly greater effects with the normal 10 mg dose.||I only use Zyrtec on an as needed basis about once per week most of the year and two to four times per week during the spring pollen season. A 5 mg dose works great for controlling my allergy symptoms. Both my doctor and pharmacist said it was okay to cut the 10 mg tablets in half, so, I am using a pill cutter to do that.||M||62||5 years ||8/25/2006|
