| 1 | Allergies | Heart palpitations and arrhythmia (bigeminy) | I felt great when I had been on Zyrtec for a few weeks, but then I started having heart palpitations/fluttering, and sometimes my heart felt like it was going to pound right out of my chest. Every day it got worse, so I went back to the doctor and she found I was in bigeminy (arrhythmia). She referred me to a cardiologist and an endocrinologist, and all their tests came back A-OK. After six weeks I was so fatigued that I could barely work, and at that point I started my own research online. I found a few accounts similar to my own, and I took myself off the Zyrtec. The heart palpitations started decreasing in 2 days and in a few weeks they were gone. Goodbye Zyrtec! | F | 34 | 6 weeks | 12/4/2006 | 3 | allergies | I was taking zyrtec-d and the decongestant raised my blood pressure, giving me migraines. Stopped the med, much fewer migraines (I already had migraines to begin with). Plus, when I stopped taking it, I was sooo itchy for weeks that I had to take other histamines periodically just to stand it. You need to wean yourself off. | The antihistamine worked. I stopped taking the zyrtec-d and my allergies have been okay since it's not the season, but I wouldn't hesitate to try regular zyrtec as needed for my allergies. | F | 23 | 3 months | 12/3/2006 | 3 | Allergies, Sinusus | Appitite increase, Loss of libido,Sleepyiness. A tirade of mental problems I suppose were caused from Zyrtec,I don't truly have the right to say so since I already take Anto-depressants, but my syptoms sound awfully the same to others.It did help with allergies and sinus. | Well I never new these were SE While on them , now maybe this is the truth. I am a fairly small average guy.5,9 - 155 pounds. Well I started taking this and again at the time I did not think anything of it. I could out eat others by a mile , I mean big men, EASILY!!! I noticed decreased libido, Absolutely loss of concentration and focus, short term memory loss. And Sleepy as hell , When I first started taking this I nearly got in several wrecks trying to drive back from my Girlfriends house.Again I did not suspect Zyrtec to be causing all of this. I have a new bottle right now right in front of me that I was about to start again after being off for about 6 months, just cause I felt I should do some research just to be safe before I start back.good thing I did. One thing I want to ask , And please men comment on this. For you all who were only on Zyrtec, Did you notice say, If you did notice A loss of libido? And On top of that(maybe a direct link) maybe Delayed-ejaculation( c | M | 22 | 3 years | 11/28/2006 | 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 | 1 | sinus and allergies | I was exhausted, spacy feeling, depressed, sad and moody (not like me at all). My short term memory was non existent. I was really concerned. I ate constantly, even when I knew I couldn't be hungry. I felt bloated and heavy. My whole body hurt. I thought it was from all the sugar and junk food I was inhaling. | I ran out of my prescription a few days ago, since then I have felt nauseated and having a constant headache. I thought I was coming down with some bug. My stomach has also felt like it was in knots and I am having diarrea. I felt so bad, I didn't want to get out to go refill my prescription. Something in my spirit prompted me to google zyrtec. Thank God for this website. I am relieved to know that I'm not losing my mind! I will not be taking zyrtec ever again. | F | 51 | 30 days | 11/21/2006 | 3 | Alergy | My son is on both zyrtec and singular. He was checked by a ped. phyc., speech theripst, and attends occupational therapy. We adopted him and he had hypothyiriodism and a deformity of the throat. After a toncil and adnoidectomy he began the meds to help with bad allergy and asthma symtoms. This child has become more and more valcanic in his behaviors. He has such a sweet character yet finds himself explosive and trigger happy with the responces that show extreme irritability. I Prayed last night in utter dispare as to how to address his needs. I saw myself doing a web search on the meds. Not only does this zyrtec show these effects but singular is no less a culpret. | Now I stand very concerned about withdrawl. I will print out this and the singular search I did. Why did all my conserns about these drugs fall on deaf ears all this time? I was asured that these drugs were o.k. over and over. | M | 5 | 3 years | 11/16/2006 | 3 | allergies, mold, dander, pollen | it took me so long to figure out, but I would take it before bed because it made me sleepy, but then while I was sleeping, I'd get chills, teeth chattering, and insides trembling, and then I would be having these involuntary muscle contractions, pulling me into a ball, then I'd wake up gasping like I'd run a marathon, and bad dreams! | The PA told me better to manage allergies than use "rescue" medications like OTC stuff I'd used for years with no really bad problems except for sleepiness and constipation. I'd rather put up with that than this stuff. The Zyrtec worked, but I can't be losing sleep to all that other crazy stuff going on. Singulair had similar effects on me too, worked great on allergies and asthma, but was making me have involuntary muscle contractions all night. I'm talking about big muscle contractions and maybe every 2-3 minutes all night long. | F | 52 | 1.5 years | 11/15/2006 | 2 | allergies | I have taken Zyrtec for years with no problem. I am 28 years old. My now two year old has been taking it since around 10 months. Around 18 months, he started exhibiting aggressive behaviors, such as hitting, biting, kicking, etc... His preschool teachers says, "He's not being mean; it's like he can't help it." I have now stopped the Zyrtec (as of yesterday). I am so upset to know of these possible side effects in toddlers/young children. I hope this solves our problem! | M | 2 | 1 years | 11/3/2006 | 1 | Allergies | My 5 year old son, who is very well mannered, became an absolute terror after only two weeks!! He was calm, focused, nice, understanding ... and all of a sudden he's throwing tantrums and we're being called into school daily. | Children should not take this medicine under any circumstances!! I'm really mad that no one warned us of these complications!! | M | 27 | 14 days | 11/1/2006 | 4 | SEVERE ALLERGIES SICK YEAR ROUND! | SLEEPY | I AM ALLERGIC TO DUST, RAGWEED AND CATS. ZYRTEC HIGHEST DOSE(IT HAS TRULY HELPED ME BREATH THROUGHOUT THE DAY AND GIVES ME A CLEAR PASSAGEWAY AT NIGHT. ALSO,FLONASE (GENERIC :), AND QVAR. AND A STRONG VITAMIN REGIME WHICH INCLUDES ACIDOPHILUS AND THAT HAS REALLY HELPED CONTROL MY PROBLEMS. I COUGH ALL WINTER AND THROUGHOUT THE RAGWEED SEASON USING AN INHALER TO HELP ME ALONG THE WAY! I AM BEING TREATED BY DR. KAGEN IN APPLETON, WI. ALLERGY SHOTS! SO FAR THERE IS A HUGE DIFFERENCE AND I SURVIVED THE RAGWEED SEASON WITH ONLY A FEW BAD WEEKS. HE HAS ALSO RECOMMENDED JUVENON NOT A DRUG TO HELP HEAL WITHIN''IT ALL STARTS THERE. WITHIN! | F | 42 | 1 years | 10/31/2006 | 1 | sinus | dementia | My father was given zyrtec in september for sinus trouble & to help him sleep. Within 24 hours he was showing signs of dementia. After a month his Doctor said that it was an allergic reaction to Zyrtec. Week two and there is still no improvement. More tests will be run. My father is only 65. I have been taking zyrtec for 1 and a half years. I quit cold turkey. No more night mares, I have more energy. I do not want to sleep for two to three hours during the day. My temperment has calmed down so that I do not over react to the slightest things. Maybe now the 30 pounds that I have put on will come off. Please Pray that my father gets better soon. | F | 39 | 2 years | 10/30/2006 | 1 | allergy to dogs and cats | hives | F | 62 | 6 days | 10/30/2006 | 4 | allergies and hives | None that I was aware of at the time. | I stopped taking zyrtec about 1 week ago and have had horrible itching. I thought at first it was from a new detergent but switched back to the old with no relief. Now reading this site I think I am in withdrawl. However I have never taken anything that worked so well for my allergies. I did develop a ringing in my ears shortly after starting it and wonder it anyone else has had that as a side effect? It is not going away since I stopped but it hasn't been that long yet. | F | 53 | 2 years | 10/28/2006 | 1 | Allergies | Drowsy all day long, Lethargic, Headaches, sick, depressed, shaky at times, irregular heartbeat, | I could not figure out why i was feeling so tired and completely exhausted all day long. I was talking Zyrtec at night but in the morning it was impossible to wake up. Then all day long I would feel tired and depressed. After reading this website I immediatley stopped taking zyrtec. However since i was talking it for two months it felt like my body was going through withdrawl from it. I would feel sick and at night could not sleep at all. This drug is the most HORRIBLE drug on the market and I would not reccommend this product to my own worst enemy. This product can completely ruin your body mentally, physically, and emotionaly. I would rather suffer from allergies all day long. I give it 100 thumbs down | M | 24 | 2 months | 10/27/2006 | 2 | seasonal allergies | trouble sleeping during the day during regular naptime, sore/dry throat, stomachace,loss of appetite, nosebleeds | My 2 1/2 year old was on Zyrtec liquid at night for 1 month and had these side effects. Once we went off Zyrtec, the issues stopped. Not happy. Not happy at all. | M | 2.5 | 30 days | 10/24/2006 | 1 | allergies | hands and feet swellings body aches. SLEEPINESS. DEPRESSION. I think it is a horrible drug. I stopped for a three days and was feeling much better. ( I was trying to see if Zyrtec was the problem) I took one last night. Nightmares hands,feet, backache body aches are back. I am THROUGH with Zytrec. I can take the 12.5 mg meclinzine You can ask druggist for it OTC. I will take that when I need it for allergies. I have been on Zyrtec on and off for years, and now I know I am not crazy!!!! | HORRIBLE DRUG!!!! | F | 65 | 6 years | 10/18/2006 | 2 | Allergies | My son's behavior changed so dramatically that I was looking into him seeing a child pyschologist. I noticed that his violent and depressive mood swings coincided with his taking the medication. As soon as I took him off of it he was fine! I was so relieved to see that others had the same concern. | M | 7 | 60 days | 10/16/2006 | 1 | son's cold/allergies | Within an hour of giving our 20 month old 1/2 tsp Zyrtec as the doctor prescribed, our son woke up screaming desperately. For the next 3 hours, he could not be consoled, running around, trembling and screaming as though terrorized. Occasionally he would fall asleep for a short while, only to wake up screaming again. It was really painful to watch. We were about to take him to the emergency room, but the doctor on call said to wait a while longer. He has never ever behaved like this, and he had not eaten/done anything else different, so we know it was the drug. This drug should NEVER be prescribed to children! | M | 1.5 | 1 days | 10/14/2006 | 5 | Severe allergies | Makes me tired so take it at bed time. If take it in the morning it makes me too tired. | The best antihistimine period and I have taken them all! Works on dust, mold, pet dander especially and seasonal allergies. I just love it! I wish all medicines worked as well as zyrtec. | F | 37 | 6 years | 10/10/2006 | 1 | Seasonal Allergy | My 7 year old daughter become unable to focus, had trouble concentating in school, complained of headaches, became extremely unhappy, and experienced weight gain while on Zyrtec. And, thankfully within days of switching to Singular we are seeing "our daughter" back again. | The side effects are horrible! | F | 7 | 45 days | 10/8/2006 |
