| 1 | Allergies | Horrible over the top anger about things that do not matter. I went into a rage at a drugstore because the sale price was not ringing up properly three hours after I took one single dose. So not at all like me. Horribly scary. I really understand how people can do horrible violent thing while taking this. | This is a terrible drug. It should not be sold to adults or children as in instantly creates deep dark strange anger. It also exhausted me for days afterward. I feel as if I took poison. It makes me very afraid that I bought this the day it was recalled and it was still on shelves at Walmart. I would rather sneeze 60 times in a row than want to harm people and be a raving lunatic. | F | 37 | 1 days 1X day | 5/5/2010 | 1 | Seasonal Allergies | I tried samples of zyrtec when it first came out to control my really extreme seasonal allergies. After only 2 doses I became extremely moody and aggressive and immediately discontinued use. I now use raw, local honey to control my seasonal allergies and have been symptom free for two years. | F | 24 | 2 days 15 1X day | 5/4/2010 | 2 | seasonal allergies/sinus infections | aided with allergy symptom relief, but eventually led to anxiety, depression, intense dreams/commonly waking up at night, thoughts of suicide and self harm | I was suggested to take zyrtec daily for constant allergy symptoms I started getting from living in a large dorm in Boston. I initially noticed no side effects even though I had been told about negative symptoms from a friend that her younger brother had experienced. Only now, a year later, have I realized that some of the issues I've faced in the last year were most likely a cause of this antihistamine. Unfortunately, it has been the only allergy medicine that has worked for me, but was definitely not worth the hell that I went through this past year. I'm now faced with challenges of withdrawal as I've only recently stopped taking it but would recommend to EVERYONE to look into the very negative side effects and how to best stop taking this pill as SOON AS POSSIBLE. thanks to everyone else who posted. | F | 19 | 1 years 5 or 10 mg 1X day | 5/3/2010 | 4 | seasonal and pet allergies | Maybe makes me a little tired. | I have bad allergies and Zyrtec is the best; if I go off it, I am sicker than a dog within two weeks. Recently started Flonase, felt better, then thought I could give up Zytec. I have a sinus infection and asthma (just developed), because I went off Zyrtec -- now I am back on, and it is helping. When I'd tried to go off, after three days I was itching like crazy all over, but that only lasted a day and a half (I think until I adjusted to being off). Anyway, I obviously cannot go without Zyrtec. Not being on it makes me so sick; my allergies are so bad this time of year especially, but I need to take it all year round. | F | 49 | 5 years 10 mg 1X day | 5/2/2010 | 1 | allergy | My nine year old Grandson is experiencing side effects from the use of the generic brand (cetirzine)10 mg purchased by his parents at Walmart. He is having irregular heartbeat, mental and mood changes, difficulty breathing and tightness in his chest. I have addressed these problems with his parents and they blame it on behavior problems and will not take him off of this drug. Please help other children who parents relate everything to behavior problems that is clearly being caused by this drug. The Generic drugs should also be recalled, they have many bad side effects that are being ignored by parents. Please help to get the word out about the generic drugs too so they will have to recall them too. | Do not give any of drugs to your children including the generic brand. They are all bad, stop blaming their behavior on ADHD, Aspergers, etc. It is the drug causing your children problems. Parents please wake up. I am doing what I can to get my grandson off of these drugs but unfortunately Grandparents have no rights. | M | 9 | 90 days 10 mg 1X day | 5/2/2010 | 1 | hay fever/allergies | Extreme mood swings, anger, irritability, violent behavior. | My 9 year old son has been taking Zyrtec for the past few weeks. Until I saw this website with all the comments, we thought he was losing his mind. He has been extremely angry, irritable, and impulsive. He's been violent and lashing out at my husband and I, as well as our younger daughter. When we ask him what's going on with him, he began to cry saying "I don't know. I just feel so angry." Now I know that it most definitely has to be the Zyrtec. I can't believe this. This was recommended by his pediatrician too. I had a suspicion that the Zyrtec might have been an influence. I feel aweful that we've been giving him this drug and the anger has been the end result. I'm throwing this product out. Thank you to all of the other people who made comments. | M | 9 | 2 weeks 10mg 1X day | 5/2/2010 | 3 | spring allergies | Take pill at night before bed. Does not make drowsy, but I do sleep longer once I go to bed. Sometimes I'm tired in mornings. Helps alleviate some symptoms. No other effects | F | 21 | 1 months 1X day | 4/30/2010 | 1 | Allergies | Rapid heart beat, feeling jittery, inability to concentrate, anger, anxiety, emotional downfall. | I originally started taking Zyrtec when I was 16-17 years old for seasonal allergies. I was not the same person. I was tired, moody, and generally felt "out of it". I stopped taking it after a couple of months and was fine after that. Since then I have just suffered with allergies because althought Zyrtec works the best- the side affects weren't worth it to me. Fast forward to 8 years later, yesterday I figured I would try it again as my allergies were getting really bad, and thought maybe something had changed in the last few years. After about an hour I started getting a rapid/fluttery heart beat, felt jittery, but also out of it at the same time. Could not focus on my work, and later when I met my mom, step dad, and boyfriend at a casino for dinner I got so anxious and irritated that I was holding back tears and anger the whole time. I was not the bubbly, funny, happy, goofy person I normally am. | F | 24 | 1 days 1 tablet 1X day | 4/30/2010 | 5 | Year round allergies | I haven't experienced any noticeable side effects. | I have been taking zyrtec for about 3 years. I am allergic to trees, grass, weeds, dust, mold, and animals. I had never been able to sleep with my mouth closed before I took Zyrtec. I also had very sensitive skin which was almost always itchy and would welt up when I scratched it. I couldn't wear any kind of lipstick/chapstick with color or flavor because it gave me a sore throat and made the area around my mouth turn red. Zyrtec has not completely cured my night breathing problems, but it has made them tons better. The biggest difference is that I am rarely itchy. it used to be that once I started scratching, I couldn't stop and sometimes, I would end up bleeding. I am so happy not to have to worry about that anymore. My skin still welts up if I scratch it, but I hardly ever do. I also don't have to worry about wearing chapstick or lipstick. On top of that, my seasonal allergies have gone away. Zyrtec has been great for me. | F | 21 | 10 mg 1X day | 4/29/2010 | 1 | Allergies | aggressive, hyper, angry, violent | Zyrtec worked good for my sons allergy symtoms, but not without HORRIBLE side effects. In just a couple of days my son became a completely different child. | M | 5 | 3 days 1/2 t 2X day | 4/28/2010 | 1 | Dr. diagnosed - atopic dermatitis | sleepy, irritable, angry, can't think clearly, illogical thoughts | The side effects of this drug sneaked up on me. I thought it was one of those non-drowsy drugs so the sleepy lethargic feelings were blamed on the fact that I thought I was getting older really quick. I am usually a nice even tempered person and responded with rage to someone that I love for something that may have otherwise made me mad but not vengeful. I also lectured a man in the grocery store yesterday because he took too long to pick out his lemons. Oh my gosh -- who is this insane woman? After I snapped at a few other people today I tried to analyze what was going on with me. I remembered that the Dr had given me zyrtec for my itchy skin a couple of weeks ago. I decided to look at the side effects and irritability is not given as one of the most prevalent side effects listed by the drug company. Anyway, I decided to look further and found this website and was relieved to hear that I'm most likely not losing my mind but suffering from taking this drug. I'll not take it again and hopefully my nasty alter ego will go away. | F | 49 | 2 weeks 10mg 1X day | 4/28/2010 | 3 | Tree Pollen Allergy | Severe mood swings, rage, thoughts of suicide, teeth chattering, shaking, cold sweats. | I took two pills. The first time I ended up in a massive fight with a bunch of my friends and threatened to quit my job for no reason before nearly attempting to commit suicide. The next day I was very depressed and slept for 19 hours. The symptoms went away after two days and I blew it off as just one of those things. I took a second dose later in the week and slept for 14 hours, had mild hallucinations, and was in a walking dream-like state all day. When I got home I got into another fight and threatened to knife someone I didn't agree with while making irrational arguments over absolutely nothing. I then became so depressed and suicidal that if I had had anything poisonous in the house I wouldn't be here right now - it was like it sucked all of the light and joy out of me and all that was left was emotional anguish. I had cold sweats, shaking, teeth chattering. It was like having withdrawal from a narcotic, and that's when I put two and two together. I'm normally laid back, outgoing, and friendly. This drug needs a warning label. | F | 24 | 2 days 10 mg 1X day | 4/26/2010 | 3 | Allergies Year Round | Dizziness, Vivid Dreams, Respitory Infection, Tiredness. | I've only been taking it for three days and i've already experienced really bad diziness and i have a respitory infection. But that means it is working because it's draining my nose out. Just the dizzy times are overwhelming and i've had verrrrrry weird dreams! | F | 14 | 3 days 30 1X day | 4/25/2010 | 2 | Allergies | Sleeplessness,Severe skin irritation and weight gain | Until I found this web site, I had no idea that Zyrtec could be causing the problems that I was having. I have always had sensitive skin, but lately have been having a rash on my hands and arms that I couldn’t get cleared up (skin lesions, general rash). I went to the Dermatologist and he prescribed topical medication for the rash. I used the medication for 4 weeks and wasn’t getting any better. Rather than go back to the Dermatologist and get a biopsy (which according to the doctor was the next step) I started investigation the side effects of the prescription medications that I was taking and started eliminating the ones that I didn’t absolutely have to take and still no change in my skin irritation. Now I started eliminating the OTC medications that I take. I have been off of Zyrtec for about 4 days now and my skin is finally starting to clear up (YEA!!!). I would have never guessed that Zyrtec could be causing the problem. I have also noticed that in general I am feeling better (better outlook on life, more energy, and clear headed). | F | 41 | 2 years 10 1X day | 4/25/2010 | 2 | Allergies | Sleepiness | It made me sleepy, drowsy; going back to Claritin, even though Zyrtec prevented allergy symptoms better | M | 30 | 3 days 10 MG 1X day | 4/23/2010 | 1 | For very bad hayfever | I suffered from feeling depressed, extreme anger and at one point lost control and became violent, which frightened my family and me. My wife urged me to come of the drug because she put two and two together as this was not my personality trait. This drug which is also in Pyreteze and many of the one a day allergy tablets. I went to the pharmacist in Sainsbury who looked up side effects in her book and she confirmed that depression was one of them. | I would rather suffer from hayfever than ever recommend this dreadful product! | M | 42 | 5 days 1X day | 4/22/2010 | 3 | allergies, indoors and outdoors | I was on Zyrtec in 2001 before it went OTC. I don't know if it's different being prescribed or OTC, but it worked great on my allergies and I experienced only one side effect: a ravenous appetite! I took it for a year, and somehow I didn't gain weight. I exercised a lot. Feeling like I was starving every minute was horrible. I definitely was eating more to try to satisfy the hunger pains, but it didn't matter how much I ate--I would never feel satisfied. That affected my sleep because I can't fall asleep if I feel hungry. That was such a huge side effect that I asked my doctor to put me on another medication. I've tried all kinds of allergy meds, and Zyrtec did work the second best for me. (Seldane-D was the best by far.) Other allergy meds just don't really do anything for me. But I couldn't be on a medicine with such a terrible side effect, and I'm sure I would've started gaining weight. I had talked to five other people when I was taking Zyrtec, who also took it, and the | F | 45 | 12 months 30 mg. 1X day | 4/21/2010 | 5 | Asthma/Allergy | It "cured" my asthma symptoms, except for the once a year bronchitis. I LOVED how it worked, but started noticing extreme mood swings, menstrual problems, and weight gain...about 15 pounds in one year | Just stopped 3 days ago, already feeling better, less "foggy" and less moody. Actually have energy! | F | 41 | 900 days 10 1X day | 4/19/2010 | 1 | allergies | Dizzy,foggy,"bubble guts"flatulence,nausea,etc,lips felt odd they burnt and tingled,back pain,wired and exhausted at same time. | Got zyrtec for seasonal allergies,im not a big pill person maybe once or twice a year I need anything but my face felt like it was going to split from tree pollen so I went to the store and caved on some OTC zyrtec.One measly pill in and I can breathe! Wonderful right? Well yeah and no,breathing is great racking your brain for two hours because you cannot remember the word for banana not so great.All in all im not impressed by the new generation of allergy relief that little blister pack brags about.At least one thing on the little demon pills is correct,it really does last 24 hours.....yay. | F | 34 | 1 days 10mg 1X day | 4/19/2010 | 1 | Sinuses/Ears | Mood swings, depression, extreme fatigue, weakness, dizziness | I would not recommend this medication to anyone after just one day I notice I felt angry then after the third day I was in such a horrible mood and so exhausted I would snap at anyone that came near me or looked in my direction. I would wake up and be ok but within an hour of being awake I couldn't hold my eyes open the rest of the day. It's definately not a safe drug to be taking and really should be looked into again as far as warnings and side effects are concerned. | F | 37 | 3 days 10mg 1X day | 4/19/2010 |
