| 2 | allergies | The very first pill I took I didn't sleep. I thought it was just because it was new. Less than 12 hours later I found myself yellng at my children and telling them to stay as far away from me as possible. I was angry all day, for no reason. Then when I took the 2nd dose (12 hours later) I got a severe headache and decided to google Zyrtec side effects. I cannot believe my doctor recommended this! Now I know why my husband is always grouchy! | F | 28 | 1 days | 10/7/2009 | 3 | pet dander, seasonal, sinus | I took my first dose Saturday, 2 days ago, and am struggling with whether I should take another dose. As my symptoms go, I have been feeling almost allergy free since Sunday morning. But I cannot come to grips with my emotions. I feel spaced out, disoriented, and extremely tired all while simultaneously feeling alert, sharp and clear minded. It is like I am living in a bubble. And I dont think I have really slept since taking this, since I seem to have been "awake" while dreaming the most bizarre and graphic dreams. I have even yelled out in my "sleep" . Very unusual. I go from being happy to outraged in one minute, over the most simple things. | This medicine has somehow made me feel really smart and energetic but has also dulled my senses. I cannot smell anything and feel just strange altogether. I do not think I will take it again. Being this aware of myself will drive me into the ground. | F | 41 | 2 days | 10/5/2009 | 3 | sinus problems caused by allergies | crazy and bizzare dreams and unrestful sleep which caused waking up and feeling like I'd been drugged which all led to being exhaused all the time. | I only gave a rating of 3 because it has helped my sinus problems/allergies; however, I can't handle the craziest dreams I have ever had in my life. I spend all my time asleep with my thoughts/dreams going at lightening speed all night; the dreams are all scattered snipits and don't make sense at all. Not to mention, they are dreams that have an underlying constant feeling of panic and stress. I think I would rather of sinus headaches. I have always slept very well and rarely dreamed - this pill will age me in no time flat. | F | 44 | 1 months | 10/3/2009 | 5 | seasonal allergies | no side effects. controls allergies without making me drowsy. | F | 45 | 4 years | 10/2/2009 | 1 | allergies | About an hour after taking noticed EXTREME fatigue. Allergy symptoms same. | F | 49 | 1 days | 10/2/2009 | 2 | seasonal allergies | It did help my seasonal allergy symptoms; however, the side effects were not worth it...at all. I became tired, achey, and extremely irritable after just one dose. My husband, and two teenagers have begged me to never take it again. | consider the side effects, seriously before taking Zyrtec. | F | 39 | 2 days | 9/25/2009 | 3 | Allergies | OMG. My 10 year old son has had a complete personality change after 4 weeks on Zyrtec. I just googled "Zyrtec irritabiity" and found this site. Thank you. I ordered child behavior books this afternoon because his anger is through the roof. He will never take another one! | M | 10 | 4 weeks | 9/23/2009 | 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 | 9/23/2009 | 3 | allergy | insomnia x10, energy, motivation | I'm in college, recently they were cutting down a forest behind my house. I would sleep with the windows open with a fan sucking air into my room. allergies went through the roof. started taking ZYRTEC. First day I could not fall asleep at night, didnt know if this was drug related or another source. finally after laying in bed for 5 hours I was able to fall asleep. Second try. Today. cleared up my allergies but it is now 4:30am with 2 exams tomorrow and no matter what I try I cannot fall asleep. Im wide awake ready to run a marathon. P.S. im only running on 12 hours of sleep over 2days, I would think my body wants to get a good nights sleep. | M | 22 | 2 days | 9/21/2009 | 2 | allergies | I become so irritable and angry about 12 hours after taking this drug. I frequently am in dire need of an antihistamine and all my physicians recommend zyrtec over the others. But I have a 2 yo son that tries my patience enough; at least now I know that these feelings are irrational side effects rather than a legitimate existential crisis. I have never, fortunately, taken it for an extended period of time, only 2-3 doses max. But consistently I have this irritability 12 hours in. | F | 38 | 2 years | 9/21/2009 | 1 | Allergy induced asthma | moodiness, depression, irritable | This drug is TERRIBLE! I can't believe it's sold over the counter. After just 5 days, I was so depressed, I could barely concentrate at home and work. Find another way to treat your allergies! | F | 45 | 5 days | 9/21/2009 | 5 | Chronic urticaria | no side effects | Zyrtec controls my hives along with Allegra without making my heart race. | F | 58 | 5 years | 9/19/2009 | 1 | allergies | The first several weeks, I felt great. Helped with allergies, and I had a ton of energy and motivation. Around week 4, I started experiencing extreme anxiety, depression, rage, hopelessness, sleeplessness, paranoia, and suicidal thoughts -- all of which steadily increased. It scared the crap out of me. I thought I was losing my mind. I gained 10 pounds over the 6 months I took Zyrtec. It also affected my bladder: I didn't sleep for literally nights on end, because every time I'd lie down, I'd feel my bladder spasming and would suddenly have to urinate VERY badly. I'd go, and it was as though I'd just chugged 8 glasses of water. I'd get back in bed, and two minutes later, the same thing, and this lasted ALL NIGHT. I have no idea how I could produce that much urine (sorry, this is gross), but it was clearly abnormal.It stopped as soon as I stopped taking Zyrtec. | I can't believe this drug is sold over the counter. In 2006, my doc put me on it, 1 tablet a day, because I have a history of seasonal and food allergies. After 6 months of taking it, I was trying to figure out what changed in my life when I started having the severe depression, suicidal thoughts, bladder issues, etc., and in an epiphany moment, I realized it all began when I started taking Zyrtec. I immediately saw my doc and told her what had been going on. She confirmed that some people react very badly to this drug and told me to stop taking it. I did, cold turkey, and immediately went into a severe withdrawal that lasted for 3 weeks: I got an itchy rash all over my arms, I had a headache like nobody's business that lasted for 10 days, my muscles were sore -- but within 2 days, my mental state improved drastically. The longer I was off this drug, the better I felt, and I started to immediately drop the weight I'd gained. If you take this drug, PLEASE monitor your mental state and stop taking it right away if your behavior changes for the negative, you become depressed, suicidal, etc. Some seasonal allergies can be greatly helped by changes to one's diet, so look into that as an alternative. Don't give this to child or anyone else who isn't able to articulate potential side effects. Please, please be careful. This is a very dangerous, toxic drug. | F | 34 | 6 months | 9/19/2009 | 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. Side Bar about Alleg | F | 40 | | 9/18/2009 | 1 | Allergies | Severe Itching, Sneezing, Runny nose, Headache, Insomnia | I have taken Zyrtec for about 10 years. Suffered from severe depression and anxiety. At the suggestion of my therapist I went off cold turkey. She feels that the Zyrtec along with Singulair may be causing the Depression, Anxiety and weight gain. | F | 42 | 10 years | 9/18/2009 | 1 | Allergies | My 8 yo daughter took Zyrtec once, ONCE and FAINTED at school the next day. A whole 5 mg of the stuff did it!! It was very unsettling to receive a call at work from the school nurse saying your daughter has fainted. She was eating cheese sticks for lunch and fell back as she lost consciousness. School staff were concerned she could have choked on food parts in her mouth or throat. The sad part of it all (as if the fainting was not enough) is the only reason we gave her Zyrtec was because the local pharmacy didn't have Benadryl strips when I went out on Sunday night to buy some. I'm back w/Benadryl. And will look into natural remedies as well. | Am now further convinced the FDA is really not on the ball, big pharma is out for profits ONLY. | F | 8 | 1 days | 9/16/2009 | 1 | seasonal allergies | I took Zyrtec two years ago when it was still being prescribed by doctors, and it seemed to help. I did take it after I got a steroid pack to calm my symptoms down. I stated taking it this year. I've been taking it for about 3 months now. Two weeks ago I felt very dizzy and actually had to cancel a trip because of it. I thought I took two pill within a few hours, I couldnt remember. Since then I've been being very careful, and I woke up yesterday feeling very dizzy and nauseous. I know it wasn't because I took too much. This scares me and after reading all of this, I am not taking it anymore, I didn't take it yesterday and I would NOT recommend this. | I have never felt this kind of dizziness before. I also felt very tired lately and thought it was just my allergies, but it might be the medicine. I am curious to see how I feel after a few weeks without being on it. | F | 24 | 3 months | 9/13/2009 | 1 | allergies | our son became irritable, moody, aggressive & had trouble sleeping thru the night. | a relative suggested I google side effects of Zyrtec on the chance this drug could be the cause of negative behavior in my son. Found this website & several others that made me discontinue Zyrtec. Literally, behavior improved overnight. Our son is much more compliant, sleeps great, generally happy & pleasant. I feel like my family has peace again ! | | 9/10/2009 | 1 | environmental allergies, ASTHMA | My son's behavior over the last 2 years have been worrisome to say the least...to the point that we have scheduled appts with child therapist. It is like he is constantly surrounded by a bubble of negative energy..moody, slight OCD, anxiety, facial ticks, etc. We constantly try to keep positive energy around him..He has had thoughts to hurt him self. A friend of mine who I totally respect and is very "science oriented" she would never rely on blogs..told me about her son who was on zyrtec and she took him off of it because of the behavioral changes he has experienced. it got me thinking. I was reading all of these blogs and felt like I could have written any of them. I plan to start to wean my son of Zyrtec immediately!!!! | M | 8 | 2 years | 9/7/2009 | 1 | seasonal allergies | heart racing, trouble breathing, severe anxiety, irrational thoughts, severe depression, low self esteem... | This is by far the most horrible drug EVER created!I'm so sad that I'm just now putting two and two together!My son has seasonal allergies so I've given him zyrtec for 2 weeks now. He approached me yesterday and told me that he needed to talk to me about something.I could see the concern in his eyes. He told me that he was afraid of me not loving him anymore if he told me these things. He told me that he was having very bad thoughts of hurting his family.I was needless to say shocked considering that he's the sweetest kid I know. He had also been complaining for several days about his "heart" hurting, and shallow breathing. he kept describing this weird feeling in his head,described it as a feeling of intense pressure. I spent the whole day with him trying to put possitive thoughts in his head. yesterday his allergies were bad,and just as I was about to reach for the zyrtec a little light went off. I looked up this drug and it's possible side effects. I'm so blessed that I found this website.I'm also so angry that so many of you had similar stories! The sad thing about this drug is that it is highly reccommended by so many Doctors!I would NEVER reccommend this to anyone! | M | 12 | 2 weeks | 9/5/2009 |
