| 5 | allergies | Our son was on this drug for a little over two years. His dosage continued to increase over the time period due to increase weight - he would eat all the time. That was the least of our problems. Our son was aggressive, moody, tired, I could go on forever!!! Jake was in preschool and having a difficult time focusing, getting along with others, and the teacher started to get concerned as well. I am a teacher and was going to ask the peds. for a full scale evalution, due to his behavior. To make a long story short, we had to find a new allergy dr, and he had us stop giving Jake the meds for his upcoming allergy tests. Within a few days we got our son back. He doesn't have the outbursts and other behaviors, Jake is that happy child he once was. We are grateful to have our son back, however, we feel cheated out of 2 years of his childhood. We were so grateful we found this site last year. | Would not recommend this medicine to anyone | 2 years | 1/25/2007 | 5 | zyrtec | HEADACHES FROM HELLLLLLLLLL! | Due to my Angioedema and hives I was put on 10 mg. of Zyrtec...awesome as for completely getting rid of the hives, however slight swelling currently in the upper left cheek. I was also put on Nasonex twice a day. I stopped the Zyrtec 2 days ago until I read these blogs and realized what the issue was. I had to wean myself off of it and did not due to the BAD headache and frustration. I just took half a pill and I am already feeling relief after about 25 minutes. Thank you to everyone for taking the time to write their own personal experiences, it's NOW helped me! GOOD LUCK!!!! | 40 | 2 days | 4/21/2007 | 3 | headaches from allergies | I came to this site to see if others are having the problem that I am -- and i see that they are: very sleepy in the morning, irritable, and hungry all the time. i've gained about 5 pounds already. also, when i stopped (for the above reasons) SERIOUS allergy symptoms like i've never had before -- 3 days of sneezing, migrane headache for the first time. i'm hoping to find another drug. | 6 months | 5/20/2005 | 3 | | 11/14/2002 | 3 | | 10/16/2001 | 3 | hives | I | | 2/26/2005 | 3 | | 10/25/2008 | 3 | Allergies | Check out Pfizer's fact sheet on Zyrtec: www.pfizer.com/files/products/uspi_zyrtec.pdf "The most common adverse reaction...was somnolence...6% in placebo, 11% at 5 mg, and 14% at 10 mg." Fatigue was a 5.9% incidence vs. 2.6% on placebo. Many of the other symptoms represented on this page were concomitant with Zyrtec use, albeit at less than 2% frequency. | | 8/3/2009 | 3 | seasonal allergies | 1 days 10 mg | 3/17/2015 | 3 | 1X day | 9/27/2017 | 2 | baby allergy | 1 days 2.5 | 7/21/2016 | 2 | Pollen | Helped allergies, but started having stomach and chest pain. After discontinuing Zyrtec. reactions disappeared. | 73 | 4 days 30 | 4/9/2020 | 2 | allergies | | 5/19/2009 | 2 | hives | I experienced headaches, moodiness, decreased libido. | Not sure if it helped me. Even though I only took it for six days, I was still getting hives. I would have taken it longer, but I started feeling really weird; headaches, body aches, moodiness, decreased libido. I may try it again at half the dosage and/or maybe every other day. | 41 | 6 days | 7/21/2006 | 2 | allergies | | 12/25/2000 | 2 | allergies | easily angered, angry, near violently angry - I'm an old woman who likes people and I said MF... the swear word... for the first time in my life and then I sulked because I knew they didn't hear me... crazy mood swing... sleepiness and foggy brain (could be allergies), and piercing headache to forehead... I thought I was stroking out... | fortunately this is fourth time I've experienced a medication induced personality change/reaction.. I stopped the zyrtec immediately. I started on zyrtec because claritin ( 9 years of seasonal use) seemed to fail... something that happened with a previous med that I used seasonally for years. At the pharmacy, I asked for suggestions and was told to try zyrtec. It immediately did relieve my allergy reactions... which was nice... but the side effects were horrendous. Luckily for me, over the many years I have taken meds and did diets, I have had adverse reactions and knew after I thought about it ... that my personality change... extreme anger, vocal expressions of annoyance, and depression... was not ME. I am stun by my inability to control angry impulses over the last two days I took zyrtec. I only recognized the problem about 4 hours before I was goin' to take my next 24 hour pill. I was taking a over-the-counter dose.,,10 mg. and my adverse reactions started on the second day... I only used it for three days total. I'm goin' to be sure to include zyrtec on my med allergies | 64 | 3 days 10 mg 1X day | 5/22/2012 | 1 | Allergies | Swelling of eyes and face. Itchy eyes and face. Depression, bad dreams, tiredness | I could not understand why I was not getting better. I would get so bad I could not go out in public sometimes not being able to open my eyes. I would go to the doctor and he would tell me to keep taking this pill. Now I realize all along it was the zyrtec causing these reactions. Within 4 days of stopping the pill my face is back to normal, the red scally patches are gone and I have more energy. | 57 | 3 months 1X day | 1/24/2013 | 1 | Allergies | I previously wrote on this site about my son and the terrible effects from zyrtec. I am urging all parents and patients to also write the FDA on their experience with zyrtec with the hopes that something will be done so that other parents and children won't have to suffer like we all have. Go to WWW.FDA.GOV then down to LET US HEAR FROM YOU then to REPORT A PROBLEM WITH A PRODUCT. It's very easy to complete and will only take a few minutes of your time. It's important to let the FDA know what's going on. MAYBE we can get something done.
