| 1 | allergies | I took this crap for 2 years before I realized it was causing my anxiety ,depression, fatigue, dry skin,eyes,mouth, and severe cognitive function decline. I had to quit my job because it got so bad. I am glad to have found the cause. Zyrtec is going in the garbage can where it belongs. | M | 25 | 2 years 10mg 1X day | 7/19/2011 | 1 | Allergies | Rage, depression, suicidal thoughts, aggressiveness. I thought I was going insane and almost checked in to the hospital. | F | 25 | 4 months 1 pill | 12/31/2011 | 1 | seasonal allergies | brain fog, extreme fatigue, muscle aches, drowsiness, heavy eye feeling, irritable and irrational mood changes, dry nose, stuffed nose, irritating cough. | It was awful! I took one tablet, for one day. I took it at night time and immediately felt that something was wrong. I woke up several times throughout the night, but still felt extremely tired, as though I couldn't ever wake up. When I finally woke up, extreme headache, fogginess. Felt drowsy and weak. No energy, completely lethargic all day long. I will NEVER take this medicine again, and I wouldn't advise anyone else to take it. I've never felt so out of control ever. I knew it had to be the medicine that I took for me to feel this way, but then finding this site and reading all of the other side effects, I linked my anger and irritability with it as well. SHOCKING that this is an OTC allergy med. 2 Thumbs WAAAY DOWN! | F | 25 | 1 days 10 1X day | 3/17/2012 | 1 | allergies | Sleepy, so i took it at night. when I stoppped taking it I was so itchy, then got hives! I felt like I had things crawling on me. Immediately started on allegra. Will never take zyrtec again. | F | 25 | 120 days | 3/12/2005 | 1 | seasonal allergies | tired all day, couldn't finish sexually, just wanted to sleep all day, facial tick | i've always had a slight facial tick growning up...it wasn't anything major except for the time of year that school went back in seccion.. it's great to finally find out that it's been the allergy pills all along...now that there really isnt any stress in my life i've come to the realization that it's always been the allegra..switching to zyrtec seemed to be the answer..well it wasnt..i dont recomend this drug to anyone..having sexual performance problems at 25 is a scary thing..thank god i found this website and found out it wasnt me! | M | 25 | 2 weeks | 9/13/2007 | 1 | Allergies | Very very bad headache migrain like, loss of appetite, trouble focusing, trouble paying attention, right side of neck swelled up and bothered my ears, fever, & allergy symptoms worse. I could have a head cold but I swear I was fine untill I took 3 of these pills I just got progressively worse. Dont take this over priced medicine. Advil Cold and Sinus is #1 for me. | F | 25 | 5 days | 3/17/2008 | 1 | Allergic outburst to pennicillin | My allergic hives seemed to worsen after I took zyrtec, my mouth and lips were dry ans sore and my feet and hands had swollen to the point where I didn't fit my shoes. So the doctor switched me to something else which represses my immune system so it will stop fighting the pennicillin which has already left my body days ago?? I also suddenly craved snacks and food, I ate two tubs of Ben&Jerry's in three days, I usually never eat that. The night after I stopped taking Zyrtec the hives I alreay had from the allergic reaction had become far itchier than they had ever been and I couldn't sleep all night. I took another pill just before stubmbling upon this site because I thought it might help the itch. I'm regretting that, but the itch is still not gone hours after taking the Zyrtec eventhough I hear others speak of immediate itch-relief. | After reading all of these comments I am quitting zyrtec immediately, I will take benedryl against the itch and just tough this thing out. Hopefully, since I have only taken zyrtec for a few days I will not experience the weeks of itching others talk about. in teh past I have taken zyrtec twice over a few weeks with no problems, although the allergy, just as it does now, took a ridiculously long time to disappear. I have hives from my neck to my feet, but reading your alarming itch-accounts and seeing how my itch already dramatically worsened after just 4 10mg pills I am far too afraid to continue this drug. So glad I found this site so soon. | F | 25 | 4 days | 4/3/2008 | 5 | Itchy eyes, sneezing, runny nose | None | Zyrtec has been a lifesaver. Works much better than Claritin with no side effects. I do notice that if I miss a dose, my symptoms return with a vengeance | F | 26 | 2 years 10 mg 1X day | 9/27/2011 | 5 | Seasonal allergies | none | It works, quickly and effectively, where all other non-drowsy antihistamines have failed. I take the generic Walgreens/CVS/Wal-mart version as needed (about once or twice week during the winter) and stop sniffling/sneezing within fifteen minutes! As a side note, I try not to take any medication regularly unless it's absolutely necessary, to protect against potential dependency or cumulative side effects. This may influence why I have nothing negative to report. | F | 26 | 1 years 10mg 1X W | 12/7/2010 | 5 | Severe, Year-Round Allergies | none | Zyrtec is the only allergy drug that has worked for me. Claritin and Allegra do nothing to relieve my itchy throat, eyes, and nose. There are warnings of drowsiness, but I have not experienced this, nor any other side effects related to taking this medicine. My major allergies are every type of grass, oak and pine pollen, seasonal weeds, cats, shedding dogs, dust...you name it, I'm probably allergic to it. March and April are the absolute worst months for my allergies, and Zyrtec helps to minimize my torment, though, during these months, Zyrtec cannot completely eliminate my symptoms. | M | 26 | 5 years 10 mg 1X day | 4/6/2010 | 5 | seasonal allergies | A little hyper, decreased appetite | I took this medicine about 2 years ago, but i was also taking antidepressants and didn't notice side effects. but now i'm just taking the over the counter zyrtec and i have a decreased appetite, which is great bc i tend to eat to much and am wanting to lose weight. and i am a little jittery, which is ok bc i usually don't have much energy. I would never give this too my kids tho...especially after reading the reviews | F | 26 | 2 days | 4/3/2009 | 4 | Seasonal allergies | None for the first four years. Now suddenly extreme drowsiness. | Most comments on this forum must by psychosomatic. They don't make any sense considering what's in Zyrtec, unless these people are actually referring to Zyrtec D. Also, the progressive increase in people attributing anxiety/depression/anger to the drug, when looking at posts over time from 2005 to 2008 suggests that people are simply convincing themselves that Zyrtec is to blame, as they increasingly see others claim this. Typical psychological response and a case of 'groupthink'. Simply compare early responses with latter ones. | F | 26 | 5 years | 6/15/2008 | 4 | allergies | weight gain, inability to stay focused at work, drowsiness | I came off of my birth control in December because I was gaining weight on it. My doctor put me on Zyrtec in January for my allergies adn since then I have put on 10 pounds in 3 months. I definately feel like the Zyrtec has caused the weight gain. | F | 26 | 3 months | 3/21/2006 | 3 | Seasonal Allergies | weight gain/increased appetite, irritability, mild depression | Zyrtec didn't really work that well for me by itself so my doctor gave me a nasal spray to use with it. That helped, but it still didn't get rid of my symptoms completely. The side effects aren't worth it to me so I'm going off it. | F | 26 | 60 days | 8/1/2006 | 3 | Severe environmental allergies | Weight gain, restless sleep, fatigue, lethargy | I couldn't understand gaining 15 pounds in 3 months when my diet and exercise habits had only positive changes. I attributed it to being a newly wed and moving into our newly built house. My energy and motivation level have dropped noticeably--again I assumed it was from being "settled". I'd recently started thinking I was pregnant, which isn't the case. Only today did I realize it could be the Zyrtec, which I started in November of 2007, so I ran a google search revealing I may be correct. I'm requesting my doctor prescribe something else and going off Zyrtec today. | F | 26 | 3 months | 3/6/2008 | 3 | Hard Core Seasonal Allergies | Zombiness, Short tempered. Wish I had these dream problems, they sound fun! | First of all this is the ONLY drug that works for me. I have taken everything to come down the pipes over the last 15 years. Only one other drug has worked for me and the side effects were worse, and it just got discontinued this year. When getting tested my doctor freaked out at my reactions after only a small fraction of the time I was to be tested for... you know its messed up when a doctor get scared :) Problem is, I am sitting here miserable trying to determine if my allergies are bad enough yet to take of the wrath of this pill. I'll turn into a bitchy space cadet with my head in the clouds. Not so sure I can afford it with work and friendships... | M | 26 | 3 years | 6/20/2007 | 3 | allergies | tiredness | F | 26 | 6 months | 2/22/2005 | 3 | possible allergies | its knocked me out . and made me drowsy. | M | 26 | | 11/1/2001 | 3 | Allergies | Drowsiness. | Could not stay awake with this medication. Would sleep for 10-12 hours and still feel tired after getting out of bed. I even tried splitting the pill to make 5 mg dose, but still felt very drowsy. This medication works, but the side effect is just a shame. | F | 26 | 2 days 10 mg 1X day | 7/13/2015 | 2 | Allergies | Anxiety, anti social, general sad feelings. | Had been taking this stuff for 5 years and it is now after reading your comments I can put 2 and 2 together. I though I had a disorder and I was gradually getting more anti social and anxious. This stuff is no good and its like a weigh is off my chest now. Havnt really experenced withdrawal except itchy but i'll get off this rubbish reguardless. | M | 26 | 5 years | 8/20/2009 |
