| RATING | REASON | SIDE EFFECTS FOR ZYRTEC | COMMENTS | SEX | AGE | DURATION/ DOSAGE | DATE ADDED |
| 4 | severe seasonal/environmental & pet | moodiness, chest pain, some dizzy spells, lethargy | It did not stop the sneezing and the sniffling, as well as the itchy eyes (with seasonal allergies/pet-) | F | 40 | 4 years | 4/19/2006 | 3 | Allergies | I know a common side effect is drowsiness. However,I find that I am suffering from insomnia. I also have an increased appetite causing weight gain and have experienced problems with my cycle. | My doctor put me on this drug to control my allergies but told me to take as needed. It worked for me. But I think I will stop taking it and see what happens. I'm not comfortable with the side effects I am experiencing and the comments I have read about the problems associated with discontinuing use. | F | 40 | 2 weeks | 8/11/2005 | 3 | Allergy leading to rash | Was taking medication regularly on alternate days for several years. Side-effects experienced included being tense and anxious, depressed and listless, if I did not take the medication regularly. | Have stopped using Zyrtec for about 2 months now. Somehow, the allergy is under control. During the initial couple of weeks of stopping the medication, I used another popular brand of anti-histamine whenever a mild allergy occurs. Am very glad that I stopped using Zyrtec. | F | 40 | 8 years | 4/20/2005 | 3 | allergies | feeling irritable. Not much energy. noticed a weight gain after just over a month. Watching what I am eating and walking several times a week for several miles has not helped. My feet and hands are swelling at times as if retaining water. Allergy problems have been better but I didnt have any of these side effects with Allegra D. | After finding this site and that many others have had similar problems and horrible withdraw issues I am off it! | F | 40 | 55 days | 5/1/2007 | 3 | Respiratory Allergies | Irritability | I have been taking this drug during allergy season for 2 years now. I took it almost daily from spring through fall last summer, in fact. It was my wife in fact who pointed out that this drug causes irritability. It was so subtle, in fact, that I didn't notice it -- but I was generally not a nice person while I was on this drug, and it took me a long time to figure it out. If I didn't have someone else around to point out the change in my personality, I'll bet I would never even have caught on to it. So, BEWARE of this drug. I was cranky for no reason at all while taking this. Happiness is important to me, so I won't be taking it anymore. This is a drag, because the pill really did help my allergies. Sigh. | M | 40 | 10 MG 1X day | 4/16/2012 | 3 | Hayfever | Extreme tiredness. I take it in the morning and by 7pm i can't keep my eyes open. | Great for allergies but the tiredness is unbearable. I try to restrict taking it to when i visit my sister, who has five cats. Makes it hard to drive home though. | F | 40 | 3 years | 2/6/2006 | 3 | allergies | Severe itching and irritability when trying to stop taking it | I started taking zyrtec on occasion for seasonal or pet allergies, and quickly found myself itching, angry and moody when I don't take it. It worked relatively well on my allergies, but after 10 years of being on daily pill I started getting sudden severe allergic reaction to unknown allergen in my house, that is not controlled by zyrtec at all. | F | 40 | 10 years | 1/25/2010 | 3 | suggested for winter allergies | Depressed, ill tempered, overly emotional. Like a super bad case of PMS-ing only I wasn't! Also had bad headaches for the first few days. Took only for just under two weeks. Helped w/allergy symptoms but I did not feel it was worth the side effects. | Additionally when I went off Zyrtec, I developed a major migraine type headache followed by extreme nausea and fatigue. Went away after a day. | F | 40 | 12 days | 4/3/2009 | 2 | Allergies | I lost my sense of smell and taste. | Works on the allergies, but I can't smell or taste anything anymore. | F | 40 | 3 weeks | 7/6/2009 | 2 | seasonal allergies | extreme irritability | I had fairly immediate mood issues- everyone in the family noticed. I stopped taking it- mood issues cleared up- resumed taking it mood issues came back. I don't take it anymore! | F | 40 | 10 days | 7/1/2008 | 2 | Nasal Allergies & Sinus Issues | fatigue, sluggishness, systemic body aches, depression, irritable, difficulty concentrating | I was started on Zyrtec some 3 yrs ago to help alleviate constant Sinus pressure and headaches do to allergies. The side effects were noticeable after about 3 months. Fatigue & irritability are the worst. I didn't mind to much at the time as I recognized it and living alone I was able to manage it. Now I have been trying to get off the drug for the last year and seems like every time I quit I go through a stage of feeling fine then I become extremely irritable and just bite every ones head off for the smallest of things. | M | 40 | 3 years | 11/30/2009 | 2 | Seasonal allergies | Really bad stomach pain, almost immediate weight gain | I think Zyrtec slightly alleviated my allergy symptoms, but it's not worth the side effects. How can one gain weight that quickly..!! It also really upset my stomach. Rather take Benadryl gel caps. | F | 40 | 3 days 10mg | 4/8/2015 | 2 | Allergies | When I slept on my right side I would dream that Bigfoot or chewbaca was watching me. When I would wake up I'd feel very drowsy and turn to my left side and dream a dinosaur or Godzilla was trying to swipe me with their tail. I would never take this medication. Also had sleep paralysis. | M | 40 | 4 days 5 1X day | 6/2/2010 | 1 | hay fever | Depression: feelings of hopelessness, helplessness, despair. When I stopped taking this medicine, within two days I felt as if a great dark cloud had lifted and i was myself again. | I will never, never take this medicine again. I will never allow my children to take it. I very nearly made some serious changes to my family because of what I thought were reasonable feelings; if I hadn't made the connection between my hopeless feelings and the medicine I was taking, I would likely have wrecked my and my children's peaceful home life. | F | 40 | 21 days 10 mg 1X day | 5/20/2011 | 1 | severe allergies | anger, suicidal thoughts, severe weight gain, depression, insatiable hunger, feelings of hopelessness, lack of motivation | There is a woman who commented that there seems to be a 'made up' symptoms and side effects because she has never personally had any. That is ridiculous. Your skepticism doesn't help anyone. For years I have wondered why I continued to gain weight even though I lowered my caloric intake and increased activity. I've never had trouble losing weight in the past. I started taking it in Korea where we were stationed in the military. The allergies were awful. Both my son and I had the same symptoms. Both of us were angry, hungry, irritable and depressed. When we left Korea we stopped taking it and got better. We are in South Texas now and both of us started taking it agin--even though we are in a happy situation, we became depressed, angry, suicidal and had increased hunger and weight gain again. I am happy to have found this website because after I did, I got off zyrtec and I am my happy, healthy self again. I'm losing weight and my son is more stable emotionally. Please do not criticize other people's reactions. Just because you don't have them doesn't mean they don't exist. I am also severely allergic to morphine--just because you are not, does that mean by your calculations I will not die if I take it? | F | 40 | 2 years 10mg 2X day | 9/21/2010 | 1 | seasonal allergies | I had a bad case of hives from spring seasonal allergies. I had tried Benadryl (worked, but made me very tired) and Claritin (the 24 hour dosage only lasted about 12 hours). I gave Zyrtec a try. One five milligram pill at 6 am and I was completely wiped out for the rest of the day. I felt like I had taken an entire bottle of Percocet. The next day, I was about 50% better, but still not myself. The Zyrtec did help with the itching, but I couldn't believe how awful I felt after a single dose of an over the counter medicine. I got a shot of Solu-Medrol at the doctor's office and threw away the remaining Zyrtec. | F | 40 | 1 days 5 mg 1X day | 10/1/2010 | 1 | allergies; itching | depression; extreme exhaustion; irritability;angry; vivid dreams; bloated stomach; constipation; brain fog; blurry vision; extremely hungry;felt suicidal | I would not recommend this drug to any one. I felt like ramming my car into a pole while taking this drug. I could not function at home, work;ect. I became very mean on this drug | F | 40 | 3 days 10 mg 1X day | 8/5/2010 | 1 | Seasonal allergies | Itchy hands and feet with occasional burning on the soles of my feet after 3 days without a dose | I have wanted to stop taking Zyrtec for the past year but the closest I've gotten is taking it once every 3 days which is when the itching sets in. I started my research today on the itching and realized, like so many others, that it isn't just me. My doctor told me the itching must be from an allergy to something in my house. Not so - it is definitely withdrawal from the Zyrtec. I am going to cut back to half a pill every three days and buy Claritin to help minimize the itching. After a week or two of half pill doses, I will try to stop completely. I'm determined to do this quickly. The sooner, the better. To everyone else having similar issues, I wish you the best of luck. This issue should be publicized and the exact effect this drug is having on our bodies needs to be discovered. | F | 40 | 2 years 10 mg 2X W | 11/30/2010 | 1 | pet and pollen allergies | I took it for nearly a year before realizing that my insomnia and depression were caused by Zyrtec. I went off Zyrtec simply to get the antihistamines out of my body so I could be tested for additional allergies, and my mood lifted tremendously. So, I really inadvertently discovered that Zyrtec was causing my depression. I am so angry no one told me about this when I started taking it. It would have saved me so much misery. | F | 40 | 1 years | 9/8/2006 | 1 | seasonal allergies | My 4 yr old was taking it up until a few days ago. It worked great on his symptons, but caused him to have episodes of anger! | I didn't realize what was causing my child to act so horrible until I read the comments on this Web site. I took my child off Zyrtec and now I have my old sweet child back. I was in tears when reading the comments of the other parents who had gone through the same thing with their child. I just wish I had known about it sooner. There should be a warning with this medicine! | F | 40 | 1 years | 1/3/2006 |
