 1  Allergies Facial tics My son who is 7 has been taking Zyrtec 2 years. Within the 2 years I noticed that he was blinking his eyes a lot. It went from blinking to "eye rolling" within 6 months. The eye tic was so bad that I thought that he had Terrett (sp) syndrom. I starting looking on the internet and found this web site. My son also had night terror. I stopped Zyrtec and was wondering if anyone knows how long it stays in the system? He is soooo much better without this drug although I don't know what to do about his seasonal allergies (it did work for that). M 7 2 years

 4  Allergies None I believe the sincerity of those posting here who've experienced problems with Zyrtec. However, Zyrtec works for many adults with no side effects and I would hate to see the drug denied them. My sister led me to Zyrtec after Claritin proved increasingly ineffective. Zyrtec has been wonderful. M 44 1 months

 1  allergies I only took 5 doses, I could smell before I took them even though I was sneezing,coughing, and having a runny nose. The drug cleared up my nose and took away my Total sense of smell. Today is 4-2-09, I took the pills in the 1st. week of March 09, so I have been without my smell for about a month. I only took 5 doses,2 and 1/2 days. I can not smell anything at all and even though I can still taste,it seems not as much as before. Now I find that it's really dangerous because I can't even smell smoke. I rushed to the store and got 2 smoke alarms for safety.I will now have to be more mindful of my food spoiling, cause it could look okay, but now I can't smell to be sure. I think of all the things I'm going to miss,like puppy breath( only true dog lovers knows that wonderful smell). A new doctor has given me 7 days of an antibiotic, Nasacort nose spray and 2 shots, its now day 3 and I do not think it's going to work. If I have to live with this I sure won't like it, but on the upside, when I'm picking up the dog mess in my yard from my large dog I don't smell it. And I want smell the dead skunk in the road. Has this happened with anyone else like me in just days time? F 53 3 days

 1  allergies With in two days of use I was very testy, disinterested in my relationship with my wife, on edge, and full of anxiety. The smallest things set me off. I had difficulty sleeping with horrific violent dreams. I quit taking ZYRTEC and within 3 days I was my old self. M 51 4 days

 2  Allergies, seasonal Irritability, crankiness in my 3 year old after one week of taking zyrtec. iritability, crankiness and decreased sex drive in my spouse after one week of taking zyrtec Rather deal with the Benedryl Sleepiness than the crankiness and irritability. Not sure if the side effects would snowball and get worse over time, either. F 36 7 days

 1  seasonal allergies malaise, negative thoughts, bad mood, depression I took this drug once when it was prescribed to me by a doctor, I only had a couple doses before noticing that it was affecting my emotions and I stopped. A few years later, I had forgotten about that episode and took Zyrtec again - exact same results in just two days, I've never had any medication affect me like that: a horrible feeling of depression. I'm sorry to read about all the parents who have given this to their kids. Personally, I have had the best results with Allegra, no side effects. M 41 2 days

 1  Allergies About 1 1/2 years ago I started giving children's liquid Zyrtec to my son per his Peds. Allergy Specialist. After reading this site, its like OMG... the changes in him are from the Zyrtec. He used to be a happy go lucky kid, nothing rattled him, he slept through the night. Now he is angry and mean, sleeps poorly, having concentration problems in school, having crying meltdowns, being clingy. It's like he has become a totally different child. There is no rhyme or reason to his crying fits or his angery fits. The hardest part of this for me to accept is that I did this to him, I allowed a Doctor tell me there are no side effects to this drug. When clearly there is, my son was on 1 1/2 teaspoons a day per Doctors orders. (1/2 teaspoon more then recommend dose) I am stopping it TODAY!!! Hopefully by the end of April I'll have my little sweety back. Someone should look into a class action lawsuit, this drug is harming innocent children because these Doctors and drug companies are ha To any parents who are considering this or have just started your child on this horrible drug STOP!!!!! You won't recognize your child if you keep them on this drug. This past year and a half has been a nightmare for me to watch my son turn into this depressed, angry, exhausted, fits of crying and meltdown child. I have spent the last year trying to figure out what has happen to my son, and not been able to come up with an answer. My family has just started family counseling because I have tried everything else. I will update you at the end of April to let you know how he is doing. M 6 1 years

 4  Dog allergies overwhelming tiredness, Weight gain Now that I read all these comments, the light has turned on. I have been taking this drug for just about a month now, since we got a new dog for our boys, and as the weeks have gone on, the problems have added up. I had been waking at night, which I thought was because of the allergies, and have been literally falling asleep while typing at my desk at work. I even went so far as to call my doctor, and had a blood test to check my thyroid levels. I am on many medications, so it may be a combination of things; we'll see when I stop taking it what will happen. Hopefully I'll fit into my clothes again too!! F 35 4 weeks

 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

 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

 1  Hives, seasonal allergies Zyrtec worked for the allergies and helped somewhat for the hives. However, the side effects were horrific: I was so tired, I needed a daily nap, yet still felt lethargic. Body aches, especially around the shoulders and upper back. Vivid nightmares, and feeling groggy in the morning. Bloating and gas. Weight gain. Frequent urination. It has been almost two weeks since I discontinued it, and I am still feeling its nasty presence in my body. With all these nasty side effects, I'll take the hives instead. Doctors throw this terrible med around like candy. They claim it is effective and generally innocuous in terms of side effects. I wish they would read the hundreds of responses you have all posted.

 1  Allergy to cats I was taking 10 mg a day as a test for two weeks to see if I could live with my girlfriends cat Sam when I realized I was fatigued every day I was on it. I woke each day feeling like I didn't sleep even though I didn't actually wake up during the night. I couldn't concentrate on anything at work and didn't have motivation or the energy to workout or do just about anything. I couldn't remember anything either, my memory seemed to be affected... probably from feeling so damn tired all day. Anyway needless to say instead of taking Zyrtec, I sold her cat on ebay. Just kidding. We gave the cat away and are getting a dog. Thank god. Now maybe I'll marry her.... yeah right! If you're allergic to cats ... just get rid of the cat. duh! M 28 2 weeks

 2  yes Very cranky , hitting , yelling , shouting , getting really mad hard to control I have seem many people concerns over the ZYRTEK , CLARITIN , SINGULAR especially on kids and read about the similar syntoms as i have seen for my 7 year old. But i never realized that those symptoms could be because of any of these medicines and as many specified the doctors or FDA does not mention these as side effects anywhere. I am glad that i found this site. In 2007 I was using an ayurvedic medicine for my sons allergies which was working perfectly with no side effects but then last year i took zyrtek again as it became available OTC and was a bit lazy ordering my ayurvedic medicine online. Now I am going to order it and would like to suggest it to moms who would like to try an alternative. It is called 'Septilin' by Himalaya herbals. you can also search for it on google. And I also suggest to teach some yoga to the kids especially to asthma prone. I tried with my child and i see a lot of improvement. Doing 'Pranayama' is good for this which is a set of Breathing exercises. And in that especially 'Kapalabathi' exercise is very good. You can also search in youtube for Baba Ramdev exercises and demonstrations. You can get all the info on the above by a simple search in google. I hope this is helpful M 7 1 years

 1  allergies My 3 year old daughter became a different person She has always been a sweet, attentive, loving little girl then about a year ago she started having some real problems. She was irritable, irrational, stopped talking, regressed in her potty training, complained daily of stomach pain, and seemed to be on a different planet most of the time. At one point it got so bad we almost had her tested for Autism. We finally made the connection that her bad phases coincided exactly with allergy season and realized it was Zyrtec. I was so relieved to find this web site and see that many others have come to the same conclusion. Now that she is not taking it we have our little girl back. It is wonderful. They really need to put stronger warnings on Zyrtec. F 3 1 years

 1  suggested to take when it OTC It was absoluetly horrible. I became sick with what appeared to be Brochitus, and had just started taking Zertec when it became OTC in place of generic Clariton (as it was suggested as being much better for what appeared to be seasonal allergies (Burning eyes, watering eyes, sneezing, etc). Unfortunately my GM Dr. believing the bronchitus was bacterial and not getting better, put me on another 2 series of antibiotics (in all - it was 3 in row (1st, Z-Pac, then 10 days of Levequin, then 10 days of Amoxicillan) my lungs sounded worse and worse, weasing, bronchial spasms, persistant coughing with what sounded like loads of phlem in my lungs. The Dr knew I had just started taking Zertec and he thought "oh good" it should help. When i came back a 4th time he prescribed Levaquin again, Advair, and referred me to a Cardio Pulminary Specialist. However - that appointment couldn't be scheduled for between 2-3 weeks. within one week, I was was so distraught and having a bronchial spasm The Cardio specialist took Xrays, and breathing tests to see if I had cancer, Emphasema, or other possible deseases. He too was told that I had been on Zertec for about 2.5 months at that time, and again said "good". After 1 month of Prednizone, 35 lbs of weight gain, Advair, and Albuterol inhalents - I was still not well, I had nearly lost my voice completely and had severe weazing, coughing, phlem at times, and bronchial spasms. THEN BY CHANCE I HEARD OF SOMEONE AT WORK HAVING A COMPLETELY DIFFERENT SIDE AFFECT OF ZERTEC - POUNDING IN THE CHEST, AND THEN AS IF HIS HEART WAS FLUTTERING. When I heard this, I looked on the web for remote 4% -7% side effects - RIGHT THERE THEY WERE: Horeseness, Severe Weasing, Coughing, and Bronchial spasms. I literally felt like death warmed over at times, with sexual side affects as well. I then self diagnosed, and immediately quit Zertec and with 48 hours found dramatic improvement. Now 2 weeks later, I not only am completely clear in my lungs, but do not need any inhalents. In fact today I went on my first Cardio / Bike ride in nearly 6 mos, have complete renewed energy, and even was able to make lovve with my wife for the first time in 4 mos. I AM TOTALLY SERIOUS AND NONE OF MY DOCTORS EVEN BELIEVE ME. I KNOW IT WAS THE ZERTEC AND I HONESTLY BELIEVE HAD I NOT STOPPED IT, IT COULD HAVE KILLED ME. I want to know why the FDA made this an over the counter available drug without any of these types of warnings!?!?!? Zertec is adverti M 43 3.5 months

 4  Chronic Hives I've had chronic hives for the last 3 or so years, and the zyrtec has been a life-saver, however - in the last 3 years I have lost my libido and a lot of my creative instincts. And by lost I mean gone. I have zero interest in sex or poetry, which is weird. I feel like I'm on antidepressants. The only thing I can think of that would cause this is the zyrtec, which is the only medication I take. I would be very curious to know if zyrtec has this effect on other people. F 36 3 years

 4  Pollen Allergies Headaches due to activity The drug worked great on my allergies but it had some nasty side effects. I try to work out at the gym with some lifting, but as soon as i started taking zyrtec as soon as i would do any heavy lifting that i really had to strain to do, boom, i'd get a headache, just like that and it'd last for hours M 18 5 days

 1  Sons allergies I have a 4 yr old and a 2 yr old. They both are having bad side effects. I thought I was going mad until I started researching the drug a bit more. My oldest itches all over, mostly on the back and stomach. He is normally a very good boy, listens well, and follows directions. Lately he's been having temper tantrum melt downs over the littlest things. Which is not normal for him at all. My youngest has been the worst. He will not sleep at night. Crying spells can last 2-3 hrs with 30 min breaks of sleep in between all night long. He sleeps very sound in the afternoon for naps. He is much more irritable, and has more temper tantrums than normal. I'm taking my children off this drug for good. I wish the Physician would have explained the possible side effects before perscribing. F 30 4 days
