| 1 | relief from alergies | took one pill for the first time because it was recommended by lots of people. soon after i started getting very worried and a feeling of panic. very emotional. blurred vision! Do not take this drug. | M | 22 | 1 days | 6/3/2008 | 1 | environmental allergies | high blood pressure, weight gain, severe anxiety, aggression, unable to focus; when I miss a dose: migraine, severe nausea, heart racing | I have never been great about taking medications daily, so the symptoms kept coming and going. It was the nausea that finally made me look up side effects. After reading other symptoms on this site I was able to realize why I have been such "nut case" the last several months. I have been concerned about a sudden increase in blood pressure. I already suffered from migraines, but could not figure out why I was having them so frequently with no known triggers. I have been withdrawing now for two days; I am so sick. | F | 41 | 4 months | 6/2/2008 | 1 | sinus drainage, itchy eyes | irritability, sadness, depression, memory loss, lethargy, fatigue, quick to anger, | I really wish that I had researched this drug before I took it. It does work well, but the side effects were quite severe for me. I would not recommend it. It caused problems at home and work. I have been off it for about 5 days now, and I feel so much better. When I started forgetting things, I knew that I either had a serious health problem, or something had changed in the last two months. I narrowed it down to changing from Claritin to Zyrtec. I decided to switch back to see if it made a difference. It has made a huge difference. I will never take it again, and I am warning anyone who will listen about the very negative side effects of this over the counter drug. | M | 43 | 6 weeks | 6/1/2008 | 1 | Debilitating seasonal allergies | Fatigue, dizziness, diarrhea, bloating, irritability, sweating, headache, mood swings | The day I started my first dose I started feeling not so hot, I thought I was just coming down with a cold or caught a stomach bug, but after researching and reading up on ZYRTEC, I will NOT be taking it any longer! I have only sneezed a few times in those few days, but I'd rather deal with allergies then these side effects. | F | 25 | 3 days | 5/31/2008 | 5 | allergies | excessive weight gain! | Zyrtec really alleviated my allergic reactions (environmental and food allergies) but I gained approx. 15 lbs within a few months of being on it. | F | 36 | 500 days | 5/29/2008 | 1 | Spring allergies | Mood and personality changes | My husband, a normally gentle soul, became depressed, angry, irritable, and short-tempered within a week or two of taking a generic brand of Zyrtec. This medication had been recommended by a co-worker who also runs an allergy office. My husband stopped taking the medication. In speaking with another co-worker whose child was taking Zyrtec, she said her daughter was experiencing the same symptoms. | F | 56 | 2 weeks | 5/27/2008 | 4 | allergies | just dry mouth | I'm one of the few lucky people who are not sedated by zyrtec. In fact I am more tired when I don't take it, due to the allergies getting worse. It doesn't work as well for the past few years, but still better than anything else | F | 29 | 6 years | 5/25/2008 | 2 | seasonal allergies, | My daughter was on when she was 2 yrs old she is now almost 3. She has been having very bad tantrums, not listening, hitting. She was once very sweet and we thought it was just the terrible twos but the behavior just did not get better, only worse. After reading up on this, I know it is the zyrtec and will stop. It helped with her allergies but the behavior changes is not worth it. | F | 2.5 | 1 years | 5/24/2008 | 1 | allergies | So many they will not all fit. The worst is that now my 10 yr old has seizures. And we now have to take her to a specialest. also was told she was ADD and she isnt..... | want to warn all parents,dont give this drug to your child.. Also We the parents want to sue the company who has made this drug.... | F | 10 | 6 years | 5/24/2008 | 1 | Eczema, allergies | Out of character temper tantrums, throwing his body on the ground, inconsolability, severe frustration and crying attacks, fatigue, and difficulty waking in the morning. | We will stop use of this drug immediately and go back to Benadryl. | M | 4 | 4 days | 5/23/2008 | 4 | seasonal allergies, mild skin rash | Not sure; I took it at night, to avoid the allergy symptoms keeping me awake. I slept very well (with vivid and creepy dreams though) and felt great the next day; in fact, I was very laid back. That's why I'm writing. Usually I have chronic insomnia, severe PMS and am very high strung. I thought maybe the drug "took the edge off" my anxiety in addition to helping eliminate my allergy symptoms. Coincidence? I don't know... | The many entries here about Zyrtec effecting mood and behavior in horrible ways really bother me. Why did I seem to have the opposite effect? I don't know. It really did relieve my allergy symptoms, but it is eerie how it seemed to immediately and drastically effect my mood as well. I wondered why I've been in such a constantly good mood with positive attitude the last three days, and sleeping so well! It's just not "me." Wish I could keep taking it, but my allergy sypmtoms are gone so I am stopping. Too creepy. | F | 41 | 3 days | 5/22/2008 | 3 | Allergies | HEARTBURN!!!! which I haven't seen commented by anybody else. I don't easily get heartburn but noticed this right away. And very tired/drowsy - more so then with CTs. Plus after Day 2, I noticed my fingers and feet were very swollen. I haven't had this symptom with any other allergy med. | It works GREAT for minimizing allergy symptoms, but you have to decide if the side affects are worth it. I absolutely WOULD NOT give this medication to a young child. It's too strong. I probably won't continue to take it except under the most extreme allergy attacks. | F | 43 | 1 weeks | 5/22/2008 | 4 | ALLERGIES | SLEEPY | F | 32 | 1 days | 5/21/2008 | 2 | year round allergies | Usually would sleep a max of 6 hours. Started sleeping 10. No problem with falling asleep at night. Usually bounce out of bed ready to go in morning but not after taking this drug. Allergist insisted I take it at night and I see why. Also take Singulair. Don't like the fuzzy feeling and lack of focus with inability to start any projects. Just feel lost. | Stopped taking this two days ago. Shaky and weird feeling yesterday, and noticed hunger pangs which I haven't had for awhile and have been forcing myself to eat. Was never hungry. Great diet drug? I got two hours sleep last night. Could not fall asleep! 4:30 a.m. and woke up at 6:30. I had taken Allegra last night per my Dr and realized it's a drug I have to take in the morning. Clarinex is what we try next if Allegra doesn't work. Zyrtec had my nose running and drainage in back of throat so was it working on allergies or not?? My husband took Zyrtec and could not function, and my step-daughter tried it and can't function either. I have a two yr old granddtr on it and printed out these comments of parents who used it for children. Hope she quits giving it to her! | F | 57 | 7 months | 5/21/2008 | 1 | seasonal allergy | upset stomach, loose bowels, diarrhea. | Within two days of discontinuing Zyrtec, my symptoms disappeared. The drug was effective in minimizing my allergic problems, but for me, the side effects are not worth it. | M | 63 | 30 days | 5/21/2008 | 4 | sneezing, itchy eyes, runny nose | headache, low energy, persistant cough | great for running nose and sneezing , but i am not sure it was worth it, due to the side effects, | M | 56 | 10 days | 5/11/2008 | 1 | allergies and hives | insomnia, irritability, swelling of my body, especially my face (eyes and lips). I also experienced weight gain which I didn't notice until I abruptly stopped. After 24+ hours off the Zyrtec, I experienced stomach cramps and very loose bowels. This corrected itself after a day and I felt alive! Like a fog was lifted, however, the hives returned! My doctor didn't believe me, so I took another dose and experienced swelling of my hands, feet, face, especially my eyes and lips. I also became constipated. I feel terrible, but the hives are gone. I'm now frightened to take the medication, but don't know what to do! | F | 45 | 2 years | 5/11/2008 | 2 | Allegies | Extreme fatigue (cannot stress this enough). With Benadryl, you can at least sleep it off. With Zyrtec, the fatigue does NOT wear off; it lasts all day. It does help with allergies, but I don't think I will be taking any more of it unless I plan to lay in bed all day. | My Zyrtec is over-the-counter. | M | 23 | 6 days | 5/9/2008 | 1 | Seasonal allergies, eczema | Severe mood changes, sleep disturbances | We started our 4 year old son on Zyrtec about 1 mo ago, due to a flare of his eczema and exacerbation of seasonal allergies. Initially, his eczema seemed to improve, and the only adverse effect of the med was some drowsiness in the AM. Then, after about 2 wks, his demeanor changed from happy to depressive and he whined and complained constantly. His behavior became increasingly hyperactive, aggressive and violent. We were puzzled, since he is normally a very happy, gentle, sweet and loving child. Our concerns grew stronger when his violent outbusts became more frequent, often leading to us having to physically restrain him in order to prevent his hitting and kicking us. His tantrums also increased in length, often lasting 30-40 min at a time, after which he would collapse on the floor sobbing and inconsolable. He exhibited defiant behavior, and his listening skills completely disintegrated. On a hunch, I decided to Google Zyrtec and mood changes, since the only thing that had changed | M | 30 days | 5/8/2008 | 1 | Allergies, Chronic Sinusitus | dazed feeling, derpression, anxiety, weird thoughts, irritable | unfortunatley Zyrtec really worked pretty well on my allergies and sinus problems, but I'm almost positive they are the culprit of my dazed dizzy anxious state that I get in. The worst is I think they are causing me to awake from sleep gasping for breath!!! I think this is a seriously bad drug to take....use caution. | M | 35 | 3 months | 5/6/2008 |
