| 3 | SEASONAL ALLERGIES | ANXIETY, AGGRESSION, AGGRAVATION | Started taking Zyrtec after my claritin failed after 10 years. This Zyrtec absolutely gives me allergy relief but I am not quite certain the people around me are happy about that. I feel a change in my demeanor and attitude about an hour after taking the pill. I am less than tolerant of everyone at this point and absolutely see a change in my mood. I am still trying to decide which is the lesser of two evils...my happiness from allergy relieve or my co-workers' happiness from having me stop the medication! | F | 42 | 5 days | 4/14/2009 | 3 | seasonal allergies | Although Zyrtec works great for seasonal allergies, after about a month of daily use both my husband and myself have experienced swollen joints, especially in our hands and feet. We stop taking Zyrtec and the swollen joints have subsided. | F | 42 | 2 months 10 mg | 4/19/2015 | 2 | seasonal alergies | sudden weight gain, sore breasts, fatigue | I took this medication a few years ago when I was having bad allergies during pregnancy and loved it then - it definitely got rid of my allergy symptoms. And when I saw that I could buy it OTC I was really happy and ran out and got some when my seasonal allergies kicked in. In the past couple of weeks I have gained 5-10 lbs, despite the fact that I am now exercising regularly and more than I have since my first child was born almost 7 years ago. I realize now that I didn't notice the weight gain the first time because I was pregnant and gaining weight anyway! I have been so frustrated with the weight gain because this is not usually a problem for me and now I find myself thinking about eating all of the time and it feels like a vicious cycle - after reading all of these comments I feel a lot better and am going to stop taking the zyrtec and look for something else. I hope it comes off as fast as it piled on... | F | 42 | 3 weeks | 3/17/2008 | 2 | common allergies | tired, not motivated, weight gain (even though I doubled my cardio), weak, depressed, lack of sexual drive. | I never put these symptoms with Zyrtec, but after reading these responses, I feel both good and bad. Good because I may have an answer to feeling so tired/weak. Bad because I just purchased 5 months supply. | M | 42 | 1 years | 4/21/2008 | 1 | spring allergies | breast tenderness, heart racing, trouble sleeping | I took one pill yesterday around 8:00 p.m. I had trouble falling asleep because my heart kept racing and the heart racing kept waking me up if I did fall asleep. I noticed when I got up this morning that my breasts were tender. I don't usually have any of these problems so I decided to google side effects of zyrtec and found this website. No more for me. | F | 42 | 1 days | 4/22/2008 | 1 | seasonal and food allergies | My 5-year-old son was experiencing seasonal allergies and also hives, we think from berries, and the doctor prescribed him with Zyrtec. We didn't notice any major behavioral issues but he did begin periodically to have what we thought were night terrors - wide-eyed, screaming nightmares so vivid that it was increasingly difficult to wake him. We stopped the Zyrtec when the hives and summer sniffles went away, and the nightmares stopped, too. We still didn't put it together until last week, when spring allergies started and we resumed the Zyrtec, and the night terrors began again. | We call this drug "Nightmares in a Bottle," at least for our child. What a terrifying experience, for us and him. Please spread the word to parents. | F | 42 | 2 years | 4/21/2008 | 1 | Allergies | Extreme sleepiness and depression | I took my first and last Zyrtec pill last Friday to help me with unpleasant allergy symptomps. I should have explored this drug better! The first night I slept 11.5 hours and the whole day felt like I was under influence of heavy drugs. Sleepiness, detached feelings, depressed. I slept after lunch and in the late afternoon. Saturday night was not better, again, slept over 11 hours (I usually can't sleep longer than 7-8 hours) and got very depressed and angry. This is today and I hope that Zyrtec will get out of my system quickly. This must be a strong drug and people need to be warned. Especially those sensitive to certain medications, I am sensitive to Benadryl, but thought that Zyrtec does not have sedative effect. I hope I will be back to my old self quickly! | F | 42 | 1 days | 4/6/2008 | 1 | counter act Prednisone symptoms | I was placed on Prednisone and was experiencing some not so pleasant side affects. I saw the Dr. and she prescribed the 10 mg. Zyrtec. For one, she claims she prescribed this because of the non-drowsy effect-hahahaha!!!. I work around machinery and for the past two days that I have been on it, I have been a walking zombie, not good! Secondly, are the mood swings, not sure if the Prednisone is causing that or the Zyrtec from what I have been reading, or both. And, last but not least, is the lip thing, someone posted about swollen lips, after one day of the Zyrtec, I woke yesterday to 3 canker sores on my lip and swelling. I have decided to not take anything today, I want to feel like me again. | F | 42 | 2 days | 5/9/2007 | 1 | tree pollen allergy | HIVES, ITCHY skin, mood swings, depression. | I was put on Zyrtec for mild spring season tree pollen allergies and can not stop taking it...every time I try to stop Zyrtec, I break out in hives and have itchy skin all over. | F | 42 | 3 years | 8/6/2004 | 1 | seasonal allergies | I am so glad to read that other people are having the same side effects that I am and I am not losing my mind. I have become depressed, irritable, angry, and can't stop eating - all since starting Zyrtec 13 days ago. I am stopping it today though. I can't tolerate these side effect any longer. I don't think my family can either. | F | 42 | 13 days 10 mg 1X day | 9/17/2010 | 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 | 1 | Allergies | Complete change of mental state. | Glad I found this site. Started taking yesterday and have been in a complete bitter state since. This drug may work for some or it wouldn't be so popular but for others... watch out. If you take and your nose clears up but you wish everyone around you would just drop dead and you curse everytime your phone rings... probably not the drug for you. Glad it only took my 24hrs to figure this out instead of the 6 months, year, 2 years it took others on this site. In addition, I have all the other negative side effects listed, increased appitite, sleepy, etc. So it must be an all or nothing proposistion. You either are fine with it and you have no side effects or you have all. Suggestion, buy the 5 pack - take one - if it works great. However, if you notice any of the negative side effects, toss them out and move on. It won't get any better, it will only get worse. | M | 42 | 2 days 10 1X day | 4/13/2010 | 1 | allergies | Depression, anxiety and severe mood swings (anger) | Clearly this drug acts as a psychotic. Very scary. Will not take again. | M | 42 | 2 weeks 10 1X day | 5/21/2010 | 1 | indoor/outdoor allergies, asthma | where to begin... basically, all of the side effects listed in this forum by everyone else; and, the problems began within a couple of hours of my first dose ... culminating with suicidal thoughts, raging and irrational anger (at everyone, for not one single reason), a fever of 104F, insatiable hunger (starvation mode, for sure), and freezing extremities while sweating profusely everywhere else ... and on and on | I bought the CVS Pharmacy brand (and after checking with the Pharmacist that there aren't any side effects beyond the "possible drowsiness" listed on the packaging). He said none that he is aware of, and the product wouldn't interfere with my daily asthma medication. Well, it definitely interfere with my life, desire to live, and desire to be around anyone else; asleep at 8pm only to have disturbing dreams, heart palpitations, and a heaving chest for the next 12 hours. I finally connected the dots on Day 3 -- and stopped; then I had withdrawal symptoms for two days (the same ones others listed here in this forum) New, more comprehensive Warning information needed with this product. Please. I don't want one more person to experience 60 days of hell on Earth as I did ... followed by 48 hours of awful withdrawal symptoms. | F | 42 | 3 days 10mg 1X day | 5/27/2010 | 1 | Environmental allergies | I am both relieved and horrified that I am not alone in dealing with the side effects with our six year old son. He was recently increased to two tsp....coincindentally his anger and aggression doubled at this time. We took him off, only to deal with hives but I don't care. The change is so positive, we have a bright, happy, loving child instead of a crazy screaming irritable one. Some one should do something, esp. since so many ADHD and autistic children might be having symptoms aggrivated with this drug. | Anyone know how to get the word out on possible side effects for our little ones? | F | 42 | 6 months | 3/26/2007 | 1 | ALLERGIES | TROUBLE BREATHING, MOOD SWINGS, EXHAUSTION, WEIGHT GAIN, DEPRESSION | I WOULD NOT RECOMMEND THIS DRUG TO MY WORST ENEMY. FURTHER STUDIES OF THIS DRUG SHOULD BE DONE IN ORDER TO KNOW THE PROFILE OF THE PERSON IT HELPS AND WHOM IT DOES NOT. | F | 42 | 15 days | 3/28/2006 | 1 | allergies | had the bloating and weight gain, then had a emotional meltdown today....no more zyrtec for me | F | 42 | 2 weeks 120 1X day | 8/22/2013 | 1 | Stop reactions to allergy shots | Extreme itchiness that lasted for months after taking the medication. Jittery when not taking the drug. | M | 42 | 6 months | 7/8/2012 | 1 | doctor insisted I use it | No side effects | Another case of the doctor insisting I use something I have used before, even though I had had no previous luck with the product. Do doctors get kickbacks, or are they just arrogant? If I go to a shoe salesman and tell the clerk I can't wear a size 3 shoe, it's not like they take me to the aisle with size 3 three shoes and try to cram them on my feet. What gives with doctors that they take feedback with a grain of salt? | F | 42 | 7 days 1X day | 1/15/2012 | 1 | sinus | I haven't started taking mines yet and just hearing these comments, I don't think I want to take it now. Now my question is, is your zyrtec you're taking regular zyrtec or zyrtec D? | F | 42 | 1 days 10mg | 9/9/2014 |
