| 1 | allergies | I became so angry over almost nothing at all. Co-workers and family noticed behavior. Would fly off handle for literally small issues. This is the second time I tried this with the same negative effects. | F | 58 | 2 weeks 10 mgs 1X day | 5/8/2010 | 4 | allergy | Had become very tired at end of day. I take it at night. If I just sat still or laid on the couch in the evening (sometimes as early as 7:30) I could fall asleep for 2-3 hours. Before Zyrtec it was at most 10 - 20 Minutes. Also I would become very irritable by days end. However during the day it almost affected me like a mood elevator. I have been feeling very good and hope it was me rather than the Zyrtec. I didn't take it one night and slept fine. The next night I awoke around 2:00A.M and couldn't get back to sleep. Had anxiety and some wierd thoughts and also felt fearful. I had similar feelings when getting of of xanax many years ago. I am on no other meds than zyrtec now! Anyone else have similar feelings getting off of Zyrtec? I am trying to find the best and safest way to get off. Any suggestions are appreciated. My sleep had become so good with zyrtec I hope some previous episodes of insomnia do not return. D. | M | 59 | 6 days | 11/27/2006 | 4 | seasonal allergies | some drowziness, but not enough to curb activities. | I only take Zyrtec in the Spring/fall when I know that I will start having issues. Knowledge of what triggers each persons allergy symptoms and when the triggers first appear I feel is crucial to using this medication to make it work. I have been prescribed Zyrtec for about 8 years. So far so good. | F | 59 | | 7/25/2009 | 2 | seasonal allergies | Restless less syndrome, rapid heartbeat, a sensation of my entire body vibrating, occasional difficulty sleeping, anxiety, tired feeling during the day. I take the tablet at night, just before bed. | It did work on the allergies. I had constant post nasal drip from mold and pollen allergies. The drip caused coughing and other typical allergy symptoms. The generic Zyrtec did clear this up quite a bit, not completely. But the side effects are too much to put up with, so I'm quitting the Zyrtec. I'd rather have allergies. | F | 59 | 90 days 10 mg 1X day | 5/13/2010 | 2 | allergy | elevated blood pressure, rapid heart beat(normally 70 BPM, went to90BPM)difficulty sleeping, easily angered with others. | Initially helped relieve a cough related allergy. Was very concerned with the high blood pressure( never had it before) and was preparing to see my MD. Even thought of going to hospital because I thought I could be on the verge of a heart attack. I mentioned symptoms to a friend who said it could be the zyrtec. Stopped taking it and three days later heart rate down to 80 BPM and blood pressure 140/100 down from 155/105. Im hoping for continued improvement back to my normal 120/80. Wow this stuff scared me! Never had any heart issues before this. Going to go back to Claritin which had barely any side affects. Fortunately no negstive withdrawal symptoms others have reported. | M | 59 | 30 days 10 mg 1X day | 3/28/2010 | 1 | Seasonal Allergies | Started Zyrec for seasonal allergies. The third day, my allergy symptoms were better. I was home alone, and stood up. Could not stand, as my legs and arms were heavy and the room was spinning. Terrified, I ran outside, so that a neighbor might see me and help. No neighbor around. I sat down, until it stopped, and stood up. Started again. Fortunately there is an emergency clinic about two minutes from my house. I hopped in the car, said a prayer, and drove there. They thought I was having a heart attack. Did an EKG. Nothing wrong. It was the stupid medication. Stopped it, and it took a couple of days before I felt myself again. Allergies returned, but I will deal with them naturally, as I cannot afford the medical bills that using Zyrtec, for only THREE days, cost me. DO NOT USE THIS DRUG. IT'S DANGEROUS. Should be taken off of the market. | F | 59 | 3 days 1X day | 10/9/2014 | 1 | serve allergies | hard to wake up in morning, mood swings, irrational thoughts, crying, anti social | It didn't occur to me that my severe mood swings had anything to do with zyrtec until I realized how out of control I was behaving and I started searching for side effects. Now I have a reason for my weird dreams in the morning and the agitation I'm feeling. There hasn't been enough coffee in the morning to help me function. I was beginng to fear I couldn't do my job and my husband was beginning to believe I was a lunatic. | F | 59 | 31 days | 9/30/2007 | 1 | Allergies | I was taking the All Day Allergy relief from the $ store and it helped with itching, however I was having suicidal thoughts and since reading all these comments I come to realize its the Zyrtec! I even went to a therapist! Then I went on Claritin D and the D is for DEPRESSION!...I am so glad I found this website through WEB MD... | I was taking it to sleep at night but couldn't get up in the morning and when I did I was a zombie! My doctor gave me NATURAL D-HIST by Ortho Molecular Products and its also non drowsy...try it...I am on it now and feeling much better...also 1,000 Vitamin C a day can stop the running nose...natural is best. | F | 59 | 6 months 10 1X day | 8/31/2013 | 1 | year-round allergies | Pounding heart, high blood pressure spikes, racing heart, extreme fatigue, chest pain | Helped allergies but side-effects sent me to ER thinking I was having a heart attack. Doctors said I had too much job stress. GP said I needed something for anxiety. My heart was pounding even when at rest. During the night I would wake up with a rapid fluttering. Thought I had heart trouble. I realized the problems started with the Zyrtec because I keep a blood pressure diary and it all coincides. Asked the pharmacist if Zyrtec could cause any of the symptoms I was having and had an AHA moment. All symptoms stopped after off of it for 4 days. When I get cold, I have an intense itch that I never had before. Hope that goes away. It is only where skin is exposed to cold - like face and hands. Will never use this drug again. | F | 59 | 31 days | 11/7/2009 | 1 | allergy | Dizzy, blurry vision, nausea, vertigo, migraine headaches, little less after discontinued for a week. | Wow I hope these symptoms completely end soon, off for 1 week so far. | F | 59 | 1 years 1 tablet | 4/4/2016 | 1 | Allergies, sinus congestion | Took at night as directed--had really disturbing dreams and a feeling of panic upon awakening. Also felt very sluggish...through process of elimination decided Zyrtec must be the culprit and discontinued, as there were no other medicines, foods or events in my life to cause this reaction. An ENT DR I saw soon afterwards said it crosses the blood/brain in about 1% of the population. My daughter-in-law and her mother reported that they had the same reaction to it. | I never experienced anything like this before with an antihistamine--drowsiness, yes, but not an overwhelming feeling of doom and panic. How can they make this an over the counter drug? It could send someone to the psych ward! | F | 59 | 1 days | 8/4/2008 | 5 | Seasonal allergies | None | My wife experiences extreme emotional outbursts while taking Zyrtec. | M | 60 | 2 days 10 mg | 6/27/2020 | 4 | allergies in my nose | Worked very well, until I stopped taking it. Now itching all over (literally head to toe.) Scalp and feet are the worst, but itches are all over the place. Six itchy days and nights and counting. | There should be a warning about withdrawals after long term daily use. | M | 60 | 1 years 10 1X day | 8/21/2019 | 4 | Allergies | A very positive side effect! I have anxiety sometimes that causes chest pain, headaches and general lousy feelings. Zyrtec seems to prevent that from happening. I sleep well and can breath better. | M | 60 | 2 months | 3/26/2009 | 3 | Springtime allergies | I got extremely depressed after taking the drug for a few days in a row. | It works very well as far as curbing the symptoms of pollen allergies. I liked it because it didn't knock me out like other allergy medications. However, I'll only take it again if I'm really suffering, and I'll certainly alert others of my mood swings. | M | 60 | 3 days 10mg 1X day | 4/9/2021 | 3 | Sneezing and running nose | Can't smell or taste anything except for very salty | Actually tested by my son who knows I hate certain smells and tastes. Drank bottle lemon juice without tasting it. Ate big bite of onion and couldn't taste it's flavor. Normally hate the smell of wine and couldn't even smell it with my nose in the glass. He knows I don't like coffee so actually gave me coffee beans and I put them in my mouth and couldn't tell any difference between the beans and small pebbles. Went to look at realestat and couldn't smell cat urine or smoke. I used to be able to smell things better than most people and now literally cannot smell anything. Think it could be dangerous as I can't smell natural gas or smoke. Am going to stop taking and hope my sense of smell comes back! | M | 60 | 5 days 10 1X day | 2/24/2013 | 2 | allergies | some drowsiness, dry eyes. Upon withdrawal the feeling of itching and pain in the eyes developed and has persisted for several days so far. It feels like there is something in the eyes yet eye exam shows nothing. Not sure it is from zyrtec withdrawal but there seems to be no other explination. | would not use it again for allergies. | M | 60 | 10 1X day | 4/15/2011 | 2 | SKIN ALLERGIES | vERY TIRE, LACK OF ENERGY | LIKE TO KNOW IF OTHER USER OF THIS MEDICATION HAD ANY EXPERIENCE WITH ZYRTEC BEING A DRUG-INDUCED PARKINSONISM. CETIRIZINE AND CINNARIZINE A KNOWN DRUG-INDUCER OF PD AND BOTH ARE DERIVATIVES OF PIPERAZINE SEE BELOW Piperazine derivatives Buclizine • Cetirizine • Chlorcyclizine • Cinnarizine • Cyclizine • Hydroxyzine • Levocetirizine • Meclizine • Niaprazine • Oxatomide | M | 60 | 5 years | 4/1/2008 | 2 | sinus/allergies | At first, the drug was a godsend. I could only take it at bedtime, and I learned that the normal dosage for me was only 1/2 of a pill. If I took a whole pill at bed time, the next morning I could barely stay awake to drive to work. After taking the drug, seasonally, for about 3-4 years, I began developing new allergies. I once had an allergic reaction to two mosquito bites on the same leg. My blood pressure shot sky-high, but a dose of Zyrtec brought everything under control. I got so I could not sleep without it. Highly addictive for me in this regard. It took me four months to kick it. I spent many long nights awake. I finally weaned myself by taking half a pill on alternate days, then dropped to a quarter of a pill, then a quarter of a pill on alternate days. Finally, I am off the drug---Thank God! I am sleeping better than I have in years, and my allergies are much better. | Was paying $80. for 30 pills, then they made it an over-the-counter drug, wouldn't you know it, just as I was getting off the drug. | F | 60 | 5 years | 4/18/2008 | 1 | Seasonal allergy | Took 1 24-hour tablet. Instantly effective on symptoms, but 4 hours later I became very drowsy, had trouble remembering things, and felt like I was in a mental fog. | I will not take it again, and cannot recommend it to anyone. | M | 60 | 1 times | 4/7/2008 |
