 1  Ragweed Allergies This med causes severe depression! Take at your own risk. They advertise it as non-sedating, that's almost laughable. It's as sedating as Benedryl. If you feel suicidal or dark depression, get off of it ASAP before you harm yourself or others. Take Quercetin for seasonal allergies from your local Health Food Store. It's a natural Mast Cell Stabilizer made from the white rind of lemons or onion peel. The allergy drug Nalcrom is the synthetic version of Quercetin. It's cheap, effective, and actually "good for you" in that it's a powerful anti-oxidant and will reduce free-radical damage (aging).   M 40 1 weeks

 1  Allergies Was extremely tired all day, regardless of when I took the drug. Althought it helped my allergy symptoms, gave up after a month of total fatigue, weight gain, and irritability. That's when the problems really began. Currently on day four after quitting the drug and withdrawal symptoms of headache and severe nausea so bad I can't sleep or work. And it keeps getting worse not better! F 40 1 months

 1  for allergies I took it and experienced numbness in hands the thumbs the worse, tired, a cough,itching hunger worse. 2 daughters took it and one nose bleeds, tired, stomach aches. the other daughter is the worse. She was itching, but now twitching a lot, her hands, eye blinking, sticking out tongue, repetition of touching her shoulders each side, her arms, her hands like she is stiffing them. Her hands she holds out with palms up a lot. Its compulsive behaivor and she doesn't stop. She has been on it for two months and these all started about 2 and half weeks ago. They seem to be getting worse. I looked up side effects and saw these postings. We stopped taking it. Its been four days and not binging, her twitches are still there but not constant, starting to slow down. Its to bad these Medical companies don't post all the warnings. Like with any drug they might not affect some people and will effect others. So the ones posting with nothing effecting them your lucky. F 40 2 days

 1  seasonal allergies fatigue, vivid dreams, stomach pain, diarrhea I am so glad to be off of this medication. I didn't have the withdrawls that some mentioned, but I couldn't believe how much better I felt after I stopped the meds. I was so refreshed in the morning and didn't feel like a zombie! I was worried I had irritable bowel syndrome or an ulcer, but the stomach pain and diarrhea stopped a week after I stopped taking Zyrtec. I'll stick with Claritan and Sudafed. F 40 6 months

 1  Year round indoor outdoor allergies Irritability, severe depression, lethargy. On this for probably 15 years after trying so many others that either didn't do the job of muting the allergies or their side effects were completely unbearable from the start. While Zyrtec works for the most part, I did notice that my body wasn't responding to the anti allergy effect as well- still suffered on this. Went off a few weeks ago because the depression is changing who I am - and I feel like I actually went ON an antidepressant, it's that much of a difference being OFF this drug. Into week 2 1/2 or 3 without: hands are swelling, hot and itching like crazy- feet to a lesser degree. Been reading that this is common withdrawal. We take these pills for years like its nothing but the withdrawal is evidence that we've become dependent on it. F 40 10 years

 1  eczema, allergies my daughter is four years old and the zyrtec side effects were just terrible. She was acting out of control and very difficult to say the least. She was very aggressive at preschool and that was a direct result of this drug as she has had no problems in the past. This was recommended to us to use by a dermatologist, but I would not recommend it AT ALL for children's use!!!!!!!!!!! F 40 5 days

 1  allergy induced asthma My 4 yr old daughter has experienced similar behavioral problems for the past year. I thought was due to an extensive remodel where I was away from her, a move and my return to work. Initially her behavioral issues presented themselves in stores and at ballet and tumbling classes with either all over the place and not listening behavior to spaciness. Behavior has escalated to rage and physical hitting directed at me, defiance, not listening. My husband and I traced back our last year and thought she may have a hearing issue but after reading all of these comments, the zrytec is going in the trash for both of my daughter and I. I have been on zrytec since April and I have experienced the sluggishness, weight gain, head in a vacumn, heart palpatations, anxiety attacks and rage. I also have been less patient with my daughter and husband which was a toxic combination for my daughter and I since we both experienced behavior changes. Thank goodness for this site.

 1  upper respiratory allergies excessive sweating, weight gain, dry skin did not put 2&2 together when I gained weight although I strenuously exercise 3-4x a week regularly. Thought I was going through early signs of menopause when I could not stop sweating and gained weight pretty severely. When the epiphany came to me one day about a month ago I stopped taking Zyrtec and immediately started itching with hives on palms of hands and upper torso ( which, thank God, has now completely subsided). My sleeping pattern has now gotten back to normal - initially after stopping the medication I did feel anxious and restless which is now gone as well. I have already lost some weight -- halleluja!!!! I cannot believe my doctor did not tell me any of these severe side effects when he put me on this medication. Unbelieveable! I will never doubt my own body again and will be my own advocat for sure!!! F 40 2.5 years

 1  Seasonal Allergies Dizziness, Eye pain, fogginess, headache, stomach pain, extreme weight gain I have been taking Zyrtec for close to 4 weeks. It really does help alleviate the allergy symptoms, however, since I started having it I have had terrible eye pain and dizziness when I try to focus. I get so tired during the day I feel as if I will pass out if I don't lie down, I can't function normally. I have been eating well and excercising and gaining weight like crazy.... It just dawned on me today that the only thing that has changed in the past month is that I started Zyrtec. I am going to the doctor tomorrow to get my eyes checked and to discuss this with him, I just want to feel normal again. F 40 30 days

 1  Allergies Depression, Sleeplessness, Unmotivated, Constipation Starting taking it and about a week and a half into it, starting feeling seriously depressed for no reason. Waking up for hours in the middle of the night. Family/Friends kept asking if everything was OK. I found myself suddenly crying for no reason. That's when I realized it must be the only medication I was taking - Zyrtec. M 40 9 days

 1  Dust Mite Allergies In My 10 year old, aggression, fatigue, uncontrolled outbursts of anger, restlessness, sleep problems. Did control the sneezing, created a very unhappy child and family. Pediatrician called it a mood disorder, recommended family therapy and meds. Zyrtec went in the garbage and peace returned to our home. Thank you for this website F 40 3 months

 1  Migraines Due To Allergies Extreme Hunger! Weight Gain! Drowsiness! Loss of Consentration! Constipation! I have been taking Zyrtec for about two months now and I have noticed in these two months I have gained 12lbs! I am completely exhausted. I have a very hard time waking up. I just noticed in the last couple of weeks the constipation. It seems like I can't concentrate on anything. I hope after this stuff gets out of my system that I am back to normal. I will have to go back to Singulair or find something else. F 40 60 days

 1  Allergies Vivid dreams when I can sleep and anxiety. I used to take it several years ago and loved it. I'm not sure if my body is responding this way because of current medication or not. My pcp knows what I am on and prescribed it. Just very disappointed I can't take it. F 40 3 days

 5  Severe Allergies None, I am an energetic morning person and I stay up until 11pm most nights and I sleep blissfully. I am not overweight and people tell me how wonderful my personality is. I surprised to see so many adverse reactions. I have tried every drug out there. Zyrtec (Cetrizine Hydrocloride) works for me. I actually have to take 10mg every 12 hours (Doc recomended) and when Cedar Pollen is very high up to 3 doses (30mg total) spread over 24 hours. I never seem to have any of the possible advertised symptoms. M 41 4 years

 5  CLARIFICATION This post is to correct the post dated 12/4 that starts "EVERYONE PLEASE READ!!!" and goes on to say that there is a difference between the prescription and OTC brands, and further states that Pfizer makes the Prescription brand Zyrtec and the OTC brand is made by "a company contracted to make a cheap OFFBRAND of the real product." This is categorically false. The prescription Zyrtec and the OTC Zyrtec are the exact same thing. McNeil has not been contracted to produce a "cheap offbrand" by any means. McNeil, a Johnson & Johnson Company, purchased Pfizer's OTC division, and thus purchased the Zyrtec brand when the FDA cleared it for non-prescription use. M 41

 5  Chronic allergies The itching!!! As with others reported here, about 2-3 days without Zyrtec the itching starts. I thought I was nuts. After several times of purposely going off the medication, it was confirmed. The itching started and was unbearable. I do get tremendous allergy relief, but I'm amazed nothing has been done to address the itching withdrawal condition. I take no other medications. F 41 2 years
