| 2 | Constant Sinus Problems | Wow this was eye opening. I was just lying in bed wondering what the heck was wrong with me! I even had my doctor set me up for blood work because I could sleep ALL day long. I have no energy and am PMSing all the time. This is all very unusual for me and was driving me crazy, until I read this. To boot, I still have PND, cough, etc....didn't seem to do much, but make me tired and irritable. | Thank you all for posting! | F | 41 | 7 days | 5/1/2007 | 2 | seasonal allergies | tired upon waking and feeling groggy all day - not my self no energy, not able to focus and feeling unmotivated | helped with sneezing, runny nose, etc but NOT worth feeling horrible all the time | F | 51 | 7 days | 4/18/2006 | 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 | 3/30/2009 | 2 | allergies | okay this is really weird but i had been taking zyrtec for about a week and it helped my allergies but i noticed when i stopped taking it about 10 days ago i got really bad anxiety, heart racing, emotional, trouble breaathing, chills i dont know if this has anything to do with not taking after i had been on it for a week but these might be bad side effects im not sure yet but it is very scary so im going to the doctor about it in a few days but if this has happend to anyone else please comment back. | F | 16 | 7 days | 6/13/2009 | 2 | Allergies | Like being drunk. Experienced dramatic ups and downs. Extremely drowsy one hour and then drastically hyperactive the next. Very nervous and paranoid all the time. Could not think clearly. | Got rid of my terrible allergies but not the drowsiness. Made me even drowsier. The effect on my personality was terrifying. I was not normal while taking this. Basically like living through 'Alice and Wonderland' without the vivid colors. Mind often felt numb which is incredibly strange because I am usually totally alert. And I was definitely taking Zyrtec and not Zyrtec-D. | F | 16 | 7 days | 5/31/2009 | 1 | Seasonal Allergies | Became agitated, depressed, irritable...violent thoughts. Normally I am very laid back and happy. Did not know this med could cause such mood problems. Worked well for allergies but not worth the problems it caused. This stuff is dangerous... | M | 38 | 7 days | 4/21/2009 | 1 | My son was taking it for allergies | Severe temper tantrums (multiple times per day), head banging, sleeplessness. | My pediatrician recommended Zyrtec for my 2 1/2 year old's allergy problems. Before he started taking it, the only real problem we had was his sleeping. He was getting maybe 5 hours/night because of his allergies. After he was on it for a week or so, he became violently aggressive. We had not had too much of a problem with hitting or kicking before this. He also began banging his head during his tantrums and wound up with several bruises. Anything could, and would, set him off. He also stopped napping, which made him even more tired and irritable. I just stopped giving it to him, and hopefully we will see a change. | F | 27 | 7 days | 6/8/2009 | 1 | Sinus Infection | Went to the doctor with a bad deep cough that I had for about a week. I was told it was an upper respatory / sinus infection and was prescribed an antibiotic, eye drop, and an antihistamine. Went to the local drug store and was told insurance would not pay for the antihistamine because it was the same thing as OTC Zyrtec and that the drug store had a generic brand which was cheaper. Started taking it on a Friday night all went well until the following Thursday night at work. Arrived at work normal time when roughly one hour into my shift I notice sweating over my entire body, dizzy, and completely unaware of my surroundings, when suddenly I found myself passed out on a hard concrete floor with seizer like symptoms. I was taken to the ER were they performed CT scan, MRI, and very painful spinal tap. All came back clear. After a stay in the hospital Friday I was looking forward to being discharged Saturday morning when all of sudden it happen once again. I was very sweaty, dizzy an | M | 44 | 7 days | 6/25/2008 | 1 | seasonal allergies | My 6 year old daughter had suffered severe side effects recently from singulair, so after those symptoms subsided we tried Zyrtec which created the same side effects which includes extreme confusion and anxiety, suicidal thoughts, bizarre sensations and hallucinations. Keep in mind that before these medications my daugher was care free. Unfortunately, the anxiety has not completely subsided. My daughter is not sure what is real and what is not anymore, and the worst part is after many tests and exams her pediatrician will not admit that the reactions were from these medications. | F | 28 | 7 days | 7/14/2008 | 1 | for Hives | I began taking prednisone and zyrtec, as recommended by my doctor for hives. I've taken one before bed for the past week. Since that time I have become increasingly agitated and anxious. Today I have felt like I had had about 20 cups of coffee and feel like I can't relax at all. I am also really bloated. | I saw my chiropractor today who is also into nutrition. I told him what was going on and he said I was most likely experiencing side effects of the prednisone and zyrtec. I can't remember everything he said, but I'm done with the prednisone and I will no longer take the zyrtec. A NATURAL ALTERNATIVE that I will use is Allerplex (made by Standard Process). My chiro told me I could take 3-4, 3 x day. It's all natural and has helped my son's seasonal allergies a lot. I wish I had taken it in the first place!!! | F | 41 | 7 days | 9/16/2008 | 1 | sinus/allergies. | Clear signs of depression. Mood swings. Weight gain. | Please I strongly recommend that everyone look at the clear side effects BEFORE TAKING ZYRTEC. | M | 47 | 7 days | 12/10/2009 | 1 | allergies | Our doctor recommended zyrtec for our 2 yr old daughter for a an extreme allergic reaction/hives(cause undetermined) we will never gives this drug to her again, never, extreme irrational temper tantrums, not a normal tantrum, aggressive odd behavior. we stopped taking giving her this drug after reviewing all these similar posts. extremely disappointed in doctor for not warning us of these possible side effects. | F | 2 | 7 days | 1/1/2010 | 1 | allergies | Fatigue, tiredness, overeating, stomach aches. | Took zyrtec for 7 days - only took 5 mg (1/2 a pill) at night before bed. Was tired, sleepy, fatigued the entire time. Also over-ate. When stopped taking Zyrtec, felt nauseated and had sinus headache. Tried Claritin as well, but it made me feel very jumpy and had hard time sleeping. | F | 29 | 7 days | 5/16/2006 | 1 | Itching due to allergic reaction | Quick to anger, depression, dizziness, weeping jags, paranoia, inability to use correct words, dangerous behaviors | Won't take again! | F | 39 | 7 days 1X D | 3/27/2013 | 1 | My 8 year old daughter became severely depressed on this medication. She could not stop crying, could not think of anything happy, and wanted to quit school because she was too afraid to walk out our front door. She is normally full of life and love, but described her heart on this med: "when I normally look through my heart everything is happy, but lately when I looked through my heart, everything was black". We thought she was going crazy and I cried at the loss of my sweet child, but then sat up in bed in the midst of this and realized the only thing different in our lives was the fact that she had started taking this med. When I did an internet search and discovered similiar anecdoes here, I was saddened for this drug's affect on many other children, but at peace because we found out what was wrong with my child. | F | 8 | 7 days 10 mg 1X D | 1/12/2012 | 1 | Allergies | I started taking Zyrtec for allergies and it stopped my blocked nose and sneezing quite well. I could not pin point why throughout the week I was angry and irritable for no reason. I woke from first thing in the morning irritable and I was on holidays. I can only describe the symptoms as similar to PMS. On the two morning that I did not take the medication I felt my normal self again but when I took the product at night before bed again I woke just about ready to throttle anyone who spoke to me. I am really disappointed that I was not warned about this type of side effect, consumers have the right to know the severity of such things. | This should not be sold over the counter!!!!! I would rather have a blocked nose than feel irritable and angry all day and everyday I took it. | F | 29 | 7 days 5mg 2X D | 1/18/2012 | 1 | doctor insisted I use it | No side effects | Another case of the doctor insisting I use something I have used before, even though I had had no previous luck with the product. Do doctors get kickbacks, or are they just arrogant? If I go to a shoe salesman and tell the clerk I can't wear a size 3 shoe, it's not like they take me to the aisle with size 3 three shoes and try to cram them on my feet. What gives with doctors that they take feedback with a grain of salt? | F | 42 | 7 days 1X D | 1/15/2012 | 1 | Seasonal allergies | Severe lethargy, depression, a numb feeling inside and out. No emotion, inability to make decisions, a feeling of despair, foggy brain, constipation, confusion. | Works for my allergies but not worth the horrible feeling that comes with it. | F | 52 | 7 days 10 MG 1X D | 4/12/2011 | 1 | Allergies | My 8 yr old son was on zyrtec for about a week for allergies but when the allergies eased up i stopped the zyrtec because i figure why take meds when you dont need them. Anyways his allergies are acting up again and so are his sisters so the doc told me yesterday to give her the zyrtec now also. For some reason I had a hunch to look it up on the internet and I came across this site..OH MY GOODNESS I am so thankful I found this page. Needless to say the Zyrtec went bye-byes and they both had benadryl before they went to bed last night. I will NOT give my kids zyrtec if the side effects are that bad. I had no clue because my son had only taken it for a week before i took him off it the first time. I wouldnt have noticed any side effects in that short amount of time.. THANK you to everyone on here for sharing your horrible stories. Now my kids wont have to go through hell! | F | 33 | 7 days | 4/26/2007 | 1 | allerigies | a fast feeling of nausea, lightheadness, shaking, just generally not feeling right | F | 46 | 7 days | 3/27/2008 | 1 | seasonal allergies | fatigue, anxiety, mood changes | I bought Zyrtec because I've been having a hard time finding 12-hour Claritin-D. I felt tired and anxious the whole time I was on it. The week before had been unusually stressful, so I assumed I was still getting over it. I saw a commercial that said that Zyrtec might make you tired, so I went out and found some more Claritin. Not only did the tiredness go away immediately, but the bad thoughts I'd been having all week immediately disappeared. | F | 30 | 7 days | 11/9/2008 | 1 | Zirtec | Mood Swings, Violent Behaviour, Vomiting, Abdominal Pain, Off Food Completley, Excessive Thirst | Took my 2 year old son to the chemist for skin allergies and was highly recommended Zyrtec Oral Liquid. Developed vomiting, behaviour issues, bad cramps, not eating, etc. Went to the doctor because I thought he was sick and was told it was a virus but with no ear infection, no throat infection and a clear chest. Only change in his diet was the Zyrtec. Took him off yesterday and almost instantly a different child. DO NOT give this to your child. Not worth the risk. | F | 23 | 7 days | 11/7/2007 | 5 | allergies | Sleepiness | F | 30 | 6 days 10 | 6/7/2012 | 5 | Itchy skin | Somewhat tired but if it stops the prickly skin itchy, I can live with it. | I started itching about 6 months ago all of a sudden, thought it was the detergent or soap. My doctor gave me zyrtec and the itching stopped within a hour. I have to take it three times a week to get relief. Without it the itching drives me crazy. Anyone else suffer from itchy skin for no apparent reason? | M | 39 | 6 days | 11/17/2005 | 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 | drowsiness | Since reducing my dosage to 5mgs per day I haven't felt the side effects listed before and, I still don't have horrible allergy symptoms. In short the lesser amount of Zyrtec is just as effective as a whole pill but the side effects are mostly gone except drowsiness for about an hour after waking. | F | 39 | 6 days 5 1X D | 9/21/2010 History | 4 | Allergies, nose congestion | Dry mouth, sleepiness | Constant desire to masturbate while watching golf on television. | M | 50 | 6 days | 6/7/2008 | 2 | Allegies | Extreme fatigue (cannot stress this enough). With Benadryl, you can at least sleep it off. With Zyrtec, the fatigue does NOT wear off; it lasts all day. It does help with allergies, but I don't think I will be taking any more of it unless I plan to lay in bed all day. | My Zyrtec is over-the-counter. | M | 23 | 6 days | 5/9/2008 | 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 | 1 | allergies | My daughter has allergies and was prescribed zyrtec to replace claritin after having pneumonia twice in two months. I was told to give her the Zyrtec at night because it can cause drowsiness. I usually did that but occasionally when someone else would keep her overnight, they'd forget and give it to her in the morning. Her behavior was terrible -- aggressive and unpredictable and she's usually very sweet. I couldn't rule out the fact that she was with someone else when this happened. For the last two weeks, I ended up giving her the Zyrtec in the morning because we forgot one night and just got off track. My daughter's behavior has been awful -- to the point where her teacher even asked if she was taking something that might make her behave so differently. I decided to see if I could find some link between aggression/irritability in young children and zyrtec. I am so grateful to have found this site. We will go back to Claritin today. | F | 4 | 6 days | 4/9/2007 | 1 | ALLERGY | Within three days of starting this medication, my child developed PINK EYE (a lesser known side effect of this medication). Within four days of starting this medication, my child developed a STUTTERING problem! We pulled him off this medication!!!! | Watch your child closely if they are prescribed this medication!!!! | M | 2.5 | 6 days | 1/8/2007 | 1 | Allergies | My 4 year old son was prescribed Zyrtec and Singulair last fall. Shortly after beginning, I noticed severe behavioral changes. He become very irritable, aggressive, and non-compliant. He had taken Zyrtec before, and I didn't really notice any changes, so I attributed the behavioral changes to the Singulair. I took him off of both meds and things went back to normal. We started back on Zyrtec a week ago. Five days in, he is exhibiting the same behavioral changes as last fall. I stopped giving it to him today. | I really wish that pediatricians and pharmacists would warn parents to watch for these changes in behavior when prescribing Zyrtec. These little guys are at our mercy and don't deserve to have to feel like this. | M | 4 | 6 days | 6/4/2007 | 1 | allergies | after the 4th day starting getting severe muscle & joint pain. Then starting sweating nonstop followed by cold chills ongoing for 48hrs straight. Stopped taking the Zyrtec and now I have hives which from reading others reports is part of the withdraw. Do not take this drug. | F | 46 | 6 days | 2/6/2008 | 1 | allergies | disorientation; severe fatigue; inability to think clearly; constant sleeiness; vivid, horrible nightmares; | I was recently switched from Allegra to Zyrtec due to an unexpected pregnancy. I had taken Allegra for years with no side-effects. Immediately after taking Zyrtec, I was unable to function at all. I could only stay in bed most of the day. Thankfully, I am a teacher and this happened during summer break. I can easily see why this medication could cause suicide. I would NEVER take this medicine ever again. | F | 37 | 6 days | 6/16/2007 | 1 | Allergies | Stomach pains, tired, emotional crying spells | This drug worked great for allergy problems, however, I am thankful I found this website. I have only taken for a week & I am a completely different person. I have experienced crying spells, depression, stomach pain, depressed & tired, contant hunger. I'd rather suffer from allergies than be an emtional wreck. | F | 38 | 6 days | 8/27/2007 | 1 | Allergies | aggressive bad behavior, irritability, temper tantrums over tiny thing. Would go crazy like a wild animal then crash down to a sobbing little boy. | Never will i give this to my son!!! We know it's the Zyrtec causing this behavior for we tried it two different times. Claritin has given him the same side affects also. We would rather see him suffer the allergies than be on these meds. | M | 6 | 6 days | 3/10/2008 | 1 | Allergies | Only took it for a couple of weeks on and off, but took it steadily for about a week and became extremely lethargic, I couldn't focus, and I had a definite mood change (and definitely not in a good way). As soon as I stopped taking it I felt a definite improvement in brain activity within a day and felt better overall. I flushing it down the toilet. | M | 29 | 6 days 10 mg 1X D | 4/16/2010 | 1 | allergy to dogs and cats | hives | F | 62 | 6 days | 10/30/2006 | 1 | Allergy | My husband is taking zyrtec and I will probably divorce him. He is out of control and I can't handled it. | lunatic, irritability, aggressive. This medication shouldn't be available over the counter. | F | 28 | 6 days | 5/5/2008 | 1 | seasonal allergies | The allergy symptoms are gone, but I'll stop taking this medication because of the negative side effects. I've had headaches, dry mouth, cold sweats, nausea and extreme sleepiness. Didn't feel it would be safe to get behind the wheel of a car, as I could barely keep my eyes open even after a good night's sleep. I take the Zyrtec at bedtime. | I'll either suffer through the allergy season or seek a prescription for Flonase again. | F | 55 | 6 days | 8/8/2008 | 5 | seasonal allergies | none | I have never had any side effects as described on this page. Zyrtec allows me to be outside in the spring and fall, and not to miss work due to allergy-related secondary infections. My 3 year old daughter also takes it seasonally and she has had no side effects either. I find it very effective for seasonal allergies. | F | 32 | 5 days | 6/12/2008 | 5 | allergies | none | so far it works great | M | 49 | 5 days 10 mg 1X D | 4/16/2010 | 5 | Allergies | None | Although I wake up with a very dry mouth, this drug has helped tremendously!! | M | 31 | 5 days | 6/2/2007 | 4 | allergies | dry mouth, increased reaction to alcoholo | M | 41 | 5 days | 11/4/2001 | 4 | severe rash/hives | Slight lethargy, but eminently bearable compared to Benadryl, which knocked me out completely. | I took this to help clear up a severe rash due to an allergic reaction to sulfa drugs, and it made the hives disappear fairly quickly, within 2 or 3 days. It was supposed to take a week, so I was very happy. However, my brother has taken it for hay fever, and it did not help him at all. It is also very expensive. I have 25 pills left and will try them for allergies in the spring, just so as not to waste $60. | F | 18 | 5 days | 8/11/2006 | 4 | allergy -not sure to what-pollens? | I was a eating machine and gained a few pounds(10LB)I was never to tired with it only the first wk.Now I dont seem to get very much relief so Im switching to claritin 10s.-its ok.. | ONE OF THE BETTER MEDICINES FOR ALLERGIES | M | 49 | 5 days | 4/17/2007 | 4 | asthma, pet dander | getting foggy, dizzy 3 x times in 5 years. ALL OF A SUDDEN QUIT WORKING. Sneezing now and using inhaler. | Going to go off and see my reaction | F | 50 | 5 days | 3/25/2006 | 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 | 3/19/2009 | 3 | SESONAL ALLERGY | STILL HAVE THE ICTCHY EYES AND SNEEZING...IT'S WORKING FOR THE STUFFY NOSE BUT NOT FOR THE ITCHY EYES. | NO ADDITIONAL | F | 32 | 5 days | 3/24/2009 | 3 | SEASONAL ALLERGIES | ANXIETY, AGGRESSION, AGGRAVATION | Started taking Zyrtec after my claritin failed after 10 years. This Zyrtec absolutely gives me allergy relief but I am not quite certain the people around me are happy about that. I feel a change in my demeanor and attitude about an hour after taking the pill. I am less than tolerant of everyone at this point and absolutely see a change in my mood. I am still trying to decide which is the lesser of two evils...my happiness from allergy relieve or my co-workers' happiness from having me stop the medication! | F | 42 | 5 days | 4/14/2009 | 3 | spring outdoor allergies | irritability, anger issues, cranky, argumentative, rudeness, negative | We've had horrible behavior issues that last long for the past few days for no reason at all. Finally tonight it dawned on my husband and I that we just started giving him the zyrtec this week. I'm taking him off tomorrow and hopefully he will be back to his old 7 year old jolly self. It was helping his spring allergies,but we'll have to find something else because I can't deal with those side effects. Also it contains parabens in the ingredients and those are not healthy for humans according to my most recent research. Alot of beauty items in fact are advertising paraben free on the packaging. | M | 7 | 5 days | 4/29/2009 | 3 | watering itchy eyes, runny nose | F | 3 | 5 days | 5/10/2009 | 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 D | 2/24/2013 | 3 | Seasonal allergies | I took the one pill once a day right before I went to bed, and it definitely relieved all my symptoms and made me feel great. HOWEVER, I noticed that--even though it had been 12 hours or more since taking the pill--I became VERY tired in the afternoon and evening. Like so tired I fell asleep! This is unlike me. | I believe this pill also gave me strange dreams, like even stranger than the ones I normally have. | F | 35 | 5 days 1X D | 4/12/2010 | 3 | seasonal allergies | Exhausted, shakey and very irritable. | Every time I take this drug to dry me out (when the Nasonex isn't cutting it) I feel like a zombi. I'm exhausted, shakey and very irritable the next day -- snapping at everything and everyone. I just want to scream. I need to find an alternative as this is not worth the relief I get from the nose drip! When my young son was on this he was also very irritable. Doing much better on Xyzol. I may need to look into that for myself. | F | 46 | 5 days 10 mg 1X D | 9/30/2010 | 3 | hives | fatigue, 1st few days I could barely get out of bed. Moody, sad, disconnected from world | less itchy, but still there. after reading about the side effects of others, I'm going to stop taking it now and see if the hives go away on their own. | F | 28 | 5 days | 4/11/2005 | 3 | Allergies and cough | Only been on this a few days, 10 mg a day, supposed to take it at night. I'm very nauseous. About 45 minutes after I take it, I don't want to think about food. My stomach is very tight and is bothering me. I almost feel like I have a fever but don't. I'm dizzy and seem to be out of it if someone calls at night after I've had the med. Very sleepy and lethargic. Only other thing I'm on is Synthroid and had it for years. | It's helped relieve pressure in my head, and if it will help to stop the coughing I've had from pollen allergies this season, I'll be grateful. I'm so groggy and just no energy. | F | 46 | 5 days | 6/1/2006 | 3 | itchy rash | The Zyrtec combined with a topical cream helped but I became agitated and irritable. I had trouble concentrating and had wierd dreams. I am taking 10mg tabs but will try 5mg then quit if I feel this way- it isn't helping THAT much. | Thanks for this site...I was wondering if anyone else felt this way. | F | 50 | 5 days | 8/30/2007 | 3 | allergies | short-term memory loss, fatigue, bad mood, mood swings, lack of concentration, decreased balance and motor skills, insomnia, anxiety, increased appetite with sugar cravings, constipation, bloody nose when dry or running. | It got rid of my severe mold(?) allergy symptoms quickly, but I felt like a zombie. The worse being lack of mental clarity and fatigue. | F | 23 | 5 days | 3/31/2008 | 3 | Allergies | Confusion, forgetting alot, talking in my sleep and sleep walking. | I've only been taking zyrtec otc for less than a week. I'm convinced my sleeping problems and forgetting things that I shouldn't be forgetting are because of the zyrtec. The first day I took it, it was in the middle of the day because my allergies were so horrible I just wanted them to be lessened a bit. Started taking them at night and now I talk in my sleep and sleep walk which I have never done. I'm also forgetting things that I shouldn't be forgetting. I can't say whether or not its helped my allergies because it was a full blown allergy attack when I first took it. It lessened my symptoms dramatically but they haven't dissapeared completely yet. I'm going to continue taking it for a while and hope for the best. | F | 25 | 5 days | 1/15/2009 |
