| 4 | Allergies | Allergy relief, Fatigue, Anxiety, Heart Palpitations, Sore Throat. | Zyrtec worked great for my allergy relief. I've moved recently and my allergies are not as bad so I only take it if my allergies are acting up. When I took it year round there were side effects, however, I found the side effects of other allergy medications to be MUCH, MUCH worse! I did feel exhausted when taking Zyrtec, but my allergies were so bad that the trade off was fine. I took the drug at night and slept wonderfully! It was just very hard to wake up! | F | 28 | 2 years 10 1X day | 9/21/2011 | 4 | Allergies | None | Has had no side effects and has reduced allergies probably 85%. I am very satisified | F | 28 | 2 months | 6/22/2001 | 4 | seasonal allergies | I have been gaining weight and feeling bloated. My wedding ring does not even fit anymore. I'm beginning to think it could be from the Zyrtec. | It has definately helped my allergies. It doesn't make me feel spaced out and weird like other allergy medicines. | F | 28 | 2 years | 11/3/2008 | 4 | hayfever | sedation | For me it works best anything else, however it makes me exremely sleepy. Far more than benadryl. So I have to take it at night before bed, whichs helps to fall asleep, but I feel groogy in the morning, probably due to the fact that I really don't get good REM sleep while on medication. I have bad allergies though, so I have to take a trade off. Honestt, the negative effects are better aren't as bad the positive effetcs. after taking t while though, the neg. effetcs are not as bad. | M | 28 | 2 years | 6/15/2007 | 3 | severe allergies, hives | numbness with tingling in all my extremities.Progressively worsened to point of pain. | I too thought Zyrtec to be a miracle drug. All my former symptoms completely disappeared. Now unfortunately I have a hard time walking; due to the numbness in my toes. I also have a hard time opening any type of jar and am overly sensitive to to heat and cold in my hands. I stopped taking Zyrtec 3 days ago and I am already getting normal sensation back to my fingers and toes. My feet feel normal. Unfortunately now all my old symptoms are starting to come back...fun for me! | F | 28 | 4 months | 6/20/2007 | 3 | Hives | Ok I took the med in the eve because I felt tired all day after taking it. So in the eve after taking it I would fall right asleep and would either sleep for like 10-12 hours or feel tired all day after waking. It seemed to work for hives. But other side effects where strange dreams, tired, anxiety attacks. | Ok I took the med in the eve because I felt tired all day after taking it.

But now I'm wondering if the sudden increase in hairloss and weight gain are now attributed to my now regular dosing of zyrtec. | F | 28 | 2 years | 1/11/2008 | 3 | hives | fatigue, 1st few days I could barely get out of bed. Moody, sad, disconnected from world | less itchy, but still there. after reading about the side effects of others, I'm going to stop taking it now and see if the hives go away on their own. | F | 28 | 5 days | 4/11/2005 | 3 | Hives | Weight gain, drowsiness & hair loss | I started taking Zyrtec for hives. My allergist told me that if I took allergy shots for 2 yrs the hives may go away. However, that did not happen. I have since stopped taking shots and now take zyrtec to control the hives. Since I have been taking zyrtec, I have gained a lot of weight. I didn't even realize that it could be a side effect of the drug till I read everyone's comments. I have been trying so hard to loose weight but it has been a lost cause. After reading everyone's comments I know realize that weight gain seems to be a common side effect. I have been taking zyrtec daily for the past 5 yrs. I am now trying to take it at the onset of hives. I have been able to go a week w/o taking it. I have been suffering from other allergy symptoms but I can deal with those. I just need it to contol the hives. As long as there are no hives I am not going to take it. | F | 28 | 5 years | 4/8/2006 | 3 | allergies | weight gain | I have been the same weight for years...started taking zyrtec on a regular basis, and have gained 6lbs in a month. Will stop taking, can't afford new wardrobe! | F | 28 | | 1/20/2009 | 3 | allergies | drowsiness, difficulties waking up in the morning, difficulties concentrating, spacing out often | I did not realize i was having problems concentrating until i began spacing out while driving and missing my exits. I was having a hard time waking up in the mornings, hitting the snooze button 5-6 times before dragging myself out of bed. But i had forgotten to take a dose one night, and woke up the next morning before the alarm without any problems. | F | 28 | 3 months | 3/27/2009 | 3 | Allergies | Weight gain, overeating, craving sugar, mild ear infection, dry mouth | I get GI disturbances when I go off this medication, my eyes have been red and dry ever since I stopped taking them. Allegra works better and it doesn't contain any lactose like reaction does. Reactine works better than benadryl for me however I don't like the side effects. Will start taking Allegra again or something natural instead. | F | 28 | 6 months 10 mg | 3/2/2015 | 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 | 2 | Seasonal allergies | I have been loosing hair... and lots of it. As a female this really seemed abnormal to me and quiet honestly scary. | This drug never seemed to work any better than allegra had. | F | 28 | 1.5 years | 1/26/2009 | 2 | Allergies | I am so thankful for this website. I thought I was losing my mind. After taking Zyrtec a couple of weeks ago for seasonal allergies, I thought my "down" mood was a result of other things. I quit for a while and took one last night. When I woke up, I was unusually irritable. Things that shouldn't upset me would throw me into a fury. Usually passive and easy-going, I realized that this medicine transformed me into something I did not like. Not that I'm happy I see others experiencing this, but this website lended some validity to my hunch that Zyrtec was causing it. | For the people running this survey, sex is male/female (biological); gender is masculine/feminine (a social trait). | M | 28 | 1 days 10mg 1X day | 6/23/2010 | 2 | Allergies | Significant weight gain. Went from 145 when I started taking it to almost 170 when I stopped. This was over a 1 1/2 span of taking the medication. | It worked great for my allergies. I slept better and had increased energy. But I could not lose the weight. Went cold turkey in December 2006 and down 5 pounds since stopping. | M | 28 | 1.5 years | 3/12/2007 | 2 | The strangest and most vivid dreams that I have ever had. It makes me feel paranoid and angry. It makes my skin feel like there's sand underneath it. I feel like the guy from The Shining but my allergies are so bad that I'm not sure what to do. | M | 28 | 1 months | 4/17/2007 | 1 | Severe Allergies | Depression, hair loss, anxiety, weight gain but I didn't have allergy problems I became a miserable person. | It works great for allergies but it made me emotionally a wreck, I thought I was crazy until I read this board and realized the reason why I felt this way. I am getting off it and can't make it past 3 days because I get horrible hives and itch, headaches, nausa. Horrible!!!!! I feel like it has taken away 8 years of me being happy. | F | 28 | 8 years | 2/21/2006 | 1 | environmental allergies | Allergies were better but noticed I put on 15 pounds and could not lose any weight. Mostly noticed in waist, hips, thighs. Now that I've been off for only 2 weeks I can tell my pants are fitting better, don't feel so "thick" in the middle. Now I realize my mind is much clearer and I have more energy! | I don't recommend this medicine if you're a woman who wants to avoid weight gain, or with concerns over feeling clear-headed. | F | 28 | 4 months | 8/10/2006 | 1 | Sinus Infection | I lost the ability to sweat during the summer of 2005. It all started after I had a sinus infection. I was given a Z-Pack and Zyrtec-D, which got rid of the sinus infection. However, my feet began to itch shortly thereafter. I visited several doctors, all of whom prescribed different antihistamines (Allegra, Hydroxizine, and Zyrtec) to treat the itching. After a while, the itching spread, and I eventually stopped sweating. Instead of sweating, my entire body was covered with a painful “prickly” sensation, as if my skin were being pierced with thousands of pins. The pain was most intense whenever I tried to exercise, and I frequently broke out in hives. Giving up all hope, I stopped taking all antihistamines in October of 2005, but the pain continued for several months thereafter. At one point, I was investigating the use of steroids to improve my condition. After considering my options, I decided to wait it out. I am very | I have done some research and discovered that in October 2005, a medical journal published an article called "Adverse Cutaneous Reactions of Systemic Antihistamines" (Current Medicinal Chemistry - Anti-Inflammatory & Anti-Allergy Agents, Volume 4, Number 5, October 2005, pp. 521-529(9). I would love to read this article. It seems the medical community is just beginning to realize that their prized antihistamines may be causing much of the trouble they are supposed to be curing. During the course of my affliction I consulted with three allergists, and they all refused to consider that I was having an allergic reaction to a drug they so frequently prescribe (even when I suggested the possibility). I only wish one of them had advised me to stop taking everything, rather than prescribing the alternative antihistamines which worsened my condition. It is my hope that my experience will assist those who have similar symptoms. | M | 28 | 5 months | 7/29/2006 |
