| 1 | allergies | My 8 year old daughter is, by nature, a little scattered and high mental energy. She was put on zyrtec by her allergist, in combination with allergy shots. We stopped the zyrtec last week when the discount mega-bottle we'd bought a few months ago ran out. Well, suddenly, we had our daughter back. She had become obnoxiously rude, unable to focus or sit still for any real amount of time, had difficulties getting to sleep, had frequent temper tantrums, argued incessantly, and generally became nearly intolerable to be around--honestly, I had thought about getting her a psych evaluation and entering into family therapy. Last night, 4 days without zyrtec, I found her quietly engaged in an art project, listening to music. We had spent the first non-aggressive, non-shouting, non-totally hyper weekend we've had in months. I am SO GLAD we stopped this horrible drug. Please, if you suspect your child's behavior has changed, take them off the zyrtec. It isn't worth it. Severe allergies are truly m | F | 8 | 160 days 1 tab 1X day | 8/9/2010 | 1 | Allergies | Intense depression, Inability to get to sleep, Inability to stay asleep, Nightmares when finally asleep! Insatiable hunger, Unexplainable anger, Consistent exhaustion! | I've only taken it for two or three weeks but I'm quitting it today, I can not have these side effects any longer. | F | 19 | 3 weeks 10mg 1X day | 8/7/2010 | 1 | allergies; itching | depression; extreme exhaustion; irritability;angry; vivid dreams; bloated stomach; constipation; brain fog; blurry vision; extremely hungry;felt suicidal | I would not recommend this drug to any one. I felt like ramming my car into a pole while taking this drug. I could not function at home, work;ect. I became very mean on this drug | F | 40 | 3 days 10 mg 1X day | 8/5/2010 | 1 | allergies | Irritability. Vivid dreams. Increase in the amount of nightly sleep. Constant tiredness. It seemed there was a ceiling in the amount of joy I could feel. | Made me feel like a zombie. Then I started taking only half a pill per day. This was enough to stop my allergies, but I still felt like a zombie. When I stopped taking Zyrtec, my old self returned, as did my sneezing, itchy mouth, and running nose. Stopped my allergies better than Clariton. But Clariton didn't make me feel like a zombie. | M | 46 | 4 weeks 10 MG 1X day | 8/2/2010 | 1 | Allergies (hayfever, cat, molds...) | Depression, extreme mood swings, Muscle pain, excessive bloating (stomach, swelling of ankles, feet, fingers), insomnia, weight gain, shortness of breath... | I can't even begin to tell you how alarmed and relieved I am to have found this site. I have been taking Zyrtec for about 3 years. If I were to run out and go a couple of days without it, I would start to notice how awful I felt. I thought it was just my allergies acting up, so I would start taking Zyrtec again. I am so glad to have found that there are others that have been suffering from the same symptoms as I have. I have been severly depressed, I have been having major moodswings (cry all the time, lash out at little things), my stomach was ALWAYS bloated like it was always about to explode, I would want to sleep for hours on end, and not go anywhere because I felt so awful. I literally thought my body was slowly shutting down. I ran out about a week and a half ago and decided to give my body a break and OH MY GOSH, I have been miserable. My muscles are always aching, I itch (of course). I decided to do a little research, and found this site. I am so glad that I have. I am going to log how my body has been changing for a month to see the changes. But as for right now, I'm still trying to get this horrible stuff out of my system. I will NEVER take Zyrtec again. | F | 32 | 3 years 1X day | 8/2/2010 | 5 | Allergies | Some drowsiness as mild "hangover" in the morning on full 10 mg dose. | I was on Claritin & Nasalcrom for awhile and found them to be only fair in controlling my often nasty allergies. Went to an allergist, had standard arm pin-prick test done which only confirmed what I already knew about my sensitivities, and was given Zyrtec 10 and Nasonex, both for daily use. It was an unbelievable improvement. Only issue was next day drowsiness, which I've nearly eliminated by taking 7.5 instead of 10 mg (tricky cutting the tablets though; and, 5 mg was not quite enough) and doing so 2 hours before bed rather than right at bedtime. Unexpected benefit was a reduction in some social anxiety I've had off and on for years, which I believe is due to a residual anxiolytic effect of Zyrtec/cetirizine as an Atarax/hydroxyzine metabolite - can't find substantiation for this anywhere but I don't think it's my imagination! | M | 50 | 14 days 7.5 mg 1X day | 7/28/2010 | 3 | Allergies | flush red cheeks, hives all over trunk of body | Frustrated that I cannot find side effects on their website or on the bottle!!!! | M | 2 | 2 days 1/2 tsp 1X day | 7/25/2010 | 5 | allergies | None | Stops my allergies, but over years I have to take more Zyrtec pills to make the same allergies to go away.... | F | 46 | 14 years 10mg 2X day | 7/23/2010 | 2 | allergies | I gave this to my 7 year old daughter instead of Claritin and we couldn't figure out why all of a sudden she would cry at the drop of a hat, act VERY angry and say "she just wishes she were happier" After stopping this a week later we noticed drastic improvement and she was back to herself. | F | 32 | 9 days 1X day | 7/23/2010 | 1 | Allergies | NOT TAKING ZYRTEC: Hives rashes extreme itching all over the body. Inflammations, agitation. | Upon trying to stop taking the "wonder drug" that is Zyrtec, I experienced extensive itching, rashes/ hives, and generally am pissed off and would like to see the inventors of Zyrtec tortured with itching powder on their private areas. | M | 47 | 1X day | 7/19/2010 | 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 | 1 | congestion | My daughter,2, started taking the target brand and every day, all day was a fight and tantrum. She started banging her head HARD. She also stopped eating which I thought the tantrums were coming from.I had forgot to give her her med. and I noticed the tantrums stopped, her behavior returned to normal, and she stopped banging her head. Its like night and day.I wouldn't recommend this for any child. Especially if you as a parent don't want to jump off a cliff! | NEED TO POST SIDE EFFECTS!!! | F | 2 | 2 months 2.5 ml 1X day | 6/28/2010 | 2 | Allergies | I am so thankful for this website. I thought I was losing my mind. After taking Zyrtec a couple of weeks ago for seasonal allergies, I thought my "down" mood was a result of other things. I quit for a while and took one last night. When I woke up, I was unusually irritable. Things that shouldn't upset me would throw me into a fury. Usually passive and easy-going, I realized that this medicine transformed me into something I did not like. Not that I'm happy I see others experiencing this, but this website lended some validity to my hunch that Zyrtec was causing it. | For the people running this survey, sex is male/female (biological); gender is masculine/feminine (a social trait). | M | 28 | 1 days 10mg 1X day | 6/23/2010 | 1 | seasonal allergies | depression, lack of concentration in school, panic attacks, fear and anxiety, anger. | My 9 yr old son was prescribed Zyrtec by his pediatrician. We noticed an immediate change in his attitude, behavior and grades. He was a very happy, motivated, straight A student. His personality completely changed. We thought his mood and behavior problems were just caused by his age and a new friend. We had no clue about the side effects of this drug until he stopped taking it just to see if his allergies were gone. After stoping the drug. It took about 10 days for the panic attacks to start(multiple times a day). He would just cry and shake and say his head felt funny. After taking him to his doctor, getting lab work done, EEG, EKG, referal to a pediatric psychologist I was told about the effects of this drug in children. I can't believe doctors are not talking to their patients about these severe side effects!!! Take your child off of this drug immediatly!!!!!!! | M | 9 | 5 months 10 MG 1X day | 6/23/2010 | 5 | seasonal allergies | None | I'm posting to counter many of the negative comments which can be attributed to other factors, and to counter the the self-selection bias. Sure I've had dizziness, problems falling asleep, and hair loss, but all of these occurred long before I started taking Zyrtec! In the interest of full disclosure though, I only take enough to counter 95% of my symptoms so I'm not "flying blind" and risking overdosing. | M | 33 | 1 years 2.5 to 5mg 1X day | 6/21/2010 | 3 | bad cat allergy | Took 24 hrs for my legs to get rid of the edema. I have not taken zyrtec to two days and so far no problems with the cat. I'm trying to see when the cat allegy kicks in so I know about how long I have between when I need to start/stop. | F | 56 | 10 1X day | 6/16/2010 Patient History | 2 | Seasonal Allergies | My 4 yr old experienced severe depression (as I call it considering she is 4). She withdrew from her favorite activities, like singing and dancing, stopped eating her favorite foods, would constantly say she felt like crying or she was sad. Did not want to go to school, would wake up ALL night long with nightmares, said her sheets were bumpy, it was crazy and my family was going crazy. She was extremely clingy and weepy, she also would have outbursts of crying or whining for no apparent reason. Took her off the zyrtec and within two weeks, I had my joyful, loving, playful, full of life daughter back. | Never taking zyrtec again, especially for extended periods of time for children....NEVER! | F | 4.5 | 2 months 5 - 7.5mg 1X day | 6/15/2010 Patient History | 1 | seasonal allergies | Bought this instead of Claritin which I have taken for years with noe problem. Within hours- stomach ache, bloating, no appetite and my mood changed. Symptoms did not go away. Took Zyrtec for three days and finally connected my gastroparesis with this OTC med. Vivid dreams started first night. Will never take this again. | F | 56 | 3 days 10 MG 1X day | 6/15/2010 | 1 | Allergies | Drowsiness, lack of concentration,lack of motivation,EXTREMELY INSANE VIVID DREAMS,hearing voices, hallucinations, ANGER, mood swings HAIR LOSS. | Last summer i found out that i didnt have a weak immune system, i just had allergies. Since then, I found Claritin did nothing for me and neither did the nose pumps, when i discovered zyrtec it was a different world. Although it cleared up all my allergies i began to notice an unusual amount of vivid dreams, sometimes even voices in my head, definitely nightmares. They would only happen 1-2 days after taking the pill. A lot of the people i talk to on a normal basis believe i've been going through serious mood swings that i never had before. People have told me that they do not see the motivation they used to see prior to taking the medication. i've also experienced hairloss on my face, primarily on my sideburns. | M | 19 | 9 months 10mg 1X day | 6/14/2010 | 1 | seasonal allergies | Severe stomach pain and bloating. 24 hour dosage did not leave me symptom free during that time period. | F | 37 | 2 days 1X day | 6/13/2010 |
