 1  Allergies My anxiety did peak after the first 6 months. Wasn't sure if it was Claritin or not? Then after 4 years of use I noticed hair loss, lack of energy, yellow jaundiced skin and eyes and found out that I have all of the symptoms iron deficiency anemia. The only med I take is Claritin. I have been off of it for 4 days now. Seems like the Claritin was possibly taking a toll on my liver. Waiting for 2nd blood test results. High bilirubin levels on the first test. M 37 4 years

 1  grass,tree,dust, dog allergies exteme dizziness, pins and needles feelings in face,hands,feet tight pressure-like wearing a head band, raising heart, shaky, terrible sad moods When I first took this yrs ago had the raising heart, jacked up on caffine type feeling and some tingling in head- but nothing as sever as A couple months ago when I took the Claritin d 24 hrs for about 8 days straight. I went to the emergency room with what I thought was a stroke. After a barage of heart and head cat scans, even mri to rule out MS because of the nueralogical symptons- I had Nuerologist summized that it was all head ache related .I had even called my allergist when this all started to ask if the medicine could cause this. He said no . I stopped taking this really scary stuff and within about 4 days symptons slowly subsided. I just happened to find this web site. I will not take this again. I want to start allergy shots but heard you have to take an anti-histamine before shots. I don't know if they all have these side effects. Anyone try shots- to avoid having to be on dangerous meds F 43 4 years

 5  allergies For the first 2 weeks of taking it each spring, I have lots of energy, possibly my heart going a bit more than normal. Also a lower appetite, but I'm not complaining about that. After that, no problems. Took care of my allergy problems. Also I was taking Claritin D. The regular Claritin gave my a very dry mouth. F 38 5 years

 5  Hayfever None at all. Hubby and I have been taking it all year round for allergies for years and have had no problems at all. I think it's important to note that people who take these drugs with no problems at all do not tend to post their comments on here, therefore all you get is the negative feedback and then form the opinion that the drug has an adverse reaction on everyone! It doesn't so don't panic when you read all the bad stuff, everyone reacts differently to drugs, and many don't react at all! F 42 5 years

 5  allergies mild dry mouth, increased flatulence, slight mental fog first week Overall works pretty well as an allergy preventative but not what I want to use for immediate relief. As someone who works in a high-allergen environment, this stuff has been very helpful for keeping my post-nasal drip, itchy eyes, and runny/stuffy nose in check. I was off it for a couple of weeks and the post-nasal drip and the associated sore throat came back with a vengeance, which scared the crap out of me. I could live without this stuff if I could get away from the city and the dusty, musty, moldy lab... but as long as I'm under those conditions, this stuff is a life-saver. F 29 5 years

 5  Seasonal Allergies No Side Effects I am amazed how people think it is always the drug do you people not realize that everyone acts differently to drugs, Ifor one had vivid nightmares with Zyrtec everyone and every drug is different. M 5 years

 5  Allergic to dust, mold, grasses None. I don't get drowsy and I don't gain weight by being constantly hungry as I have with other antihistamines. I take claritin in conjunction wit other mess for asthma and sinus problems. I work in an environment with lots of allergy triggers. It minimizes my reaction and helps me avoid sinus infections and asthma attacks. I can definitely tell the difference when I forget to take it. F 62 5 years

 4  Allergies Have taken for 5 years and seemed to have no side effects. However, I have experienced some memory problems and early on - fatigue. In the last 3 to 6 months however, I have experienced a significant loss of sense of smell and taste. Allergies were so bad for awhile over the winter I was taking 1 pill in am and another 1/2 at 6pm. Am beginning to think the loss of sense of smell and taste is related. I really didn't connect any memory, fatigue or smell and taste symptoms to the claritin. It's amazing how quickly everything gets attributed to age! It definately does a great job addressing the sneezing, nasal drip, hoarseness and sniffles. I suspect, however, long term use may present problems. F 63 5 years

 4  Allergies Anxiety, jitteryness I had been taking Claritin daily to relieve seasonal allergies for 4 or 5 years without any apparent problems. Then in the last 8 to 10 months, I started having problems with anxiety and jitters. I thought I was having heart palpitations as often my body felt as though it was vibrating, especially first thing after waking up in the morning. My wife is a cardiac RN so I asked her to listen to my heart and she found no problems. After reading about other people's symptoms on this web site, I stop taking Claritin two days ago and so far, anxiety and jitters have gone away. M 42 5 years

 4  allergies Really dry mouth, extreme fatigue, dizziness and nausea. Worked great on my allergies; all my regular symptoms cleared up within about half an hour of taking it. Unfortunately, the side-effects made me feel much worse than I felt before taking the drug. I've taken Claritin in the past, but I don't remember ever having such severe side-effects. F 21 5 years

 4  Allergies none I found that Claratin-D worked well, but without the decongestant it did nothing. So now I take it with cold medicine and it works well. It isn't enough that I can play with cats, but does a lot. M 28 5 years

 4  Extreme itching when body heat rose I was prescribed this in college for a nasty allergy that made me itch real bad when sweating..not fun. I've been taking this for over 5 years straight, every day to control this. Not having insurance I can't go see a doctor for alternative methods to control this. Recently I started trying to figure out why I'm always tired, lathargic and generally feel like crap. Had blood tests thinking I was diabetic or anemic...nothing showed up. Having read the comments on this site I now know why I'm always irritable and easily ready to snap. Worked well for my condition but I'm trying to stay off it and see what happens. I used to take it in the morning but will try to take it at night and then get off it all together. Fortunately the summer months are bearable for my itching problem but the winter months are misserable. M 29 5 years

 4  Seasonal Alergies Have taken the 12 hour version for years only when allergies got bad or when mowing the grass. This year I started using the 24 hour version everyday. My dreams have become unusual and vivid. I feel some confusion and not quite myself. Worrying more than normal. Mostly back to normal a couple days after stopping dosages. Definitely controls my allergies but concerned by the new side effects. 24 hour generic Walmart normal Claritin (not the D version). Should only be used when needed and not as a daily preventative. Would not recommend for children under 18 since they may not be able to cope with strange mental effects. Label should caution about nightmares and emotional reactions. I am thinking the 24 hour version is metabolising to fast and giving me an overdose. Will try the 12 hour version again only as needed to see if it is better. M 47 5 years

 3  Allergies Dry mouth, dry nasal passages, dry, irritated throat. Feeling of stuffyness in the ears. Feelings of doom and fear, anxiety and paranoia. Asthma symptoms developed during the fourth year of taking Claritin. While the drug completely relieved me of the hay fever and allergy symptoms, eventually I was left with the aforementioned side effects. I added the anxiety feelings only because I see others have some of these side effects from taking Claritin. I was told by my doctor to take it everyday. At that time it was prescription only. I began taking it in 2001 and stopped in 2006. My side effect symptoms began in 2005. As of today, I still have these symptoms, although the feelings of doom and fear have subsided a great deal. Is there anyone else who experienced side effects long after stopping the drug? Thank you for your response. F 53 5 years

 3  Allergies Extreme drowsiness and fatigue. I've taken Claritin off and on for 5 years. The reason I take it off and on is because it helps my congestion and itchy eyes and throat but it makes me so drowsy that Im unable to function properly during the day. Im yawning so much that my eyes are no longer watering from the allergies, but from yawning entirely too much. F 20 5 years

 3  Allergic to grass, trees, and cats At first Claritin seems to help my allergy symptoms, but after about 6-8 weeks it seems Claritin makes them worse. The same thing happened with Nasalcrom. I have noticed this pattern for a couple of years now. Very recently I got so bad that I was sneezing 10 times in a row, had extremely red and itchy eyes, etc. Wearing a dust mask and stopping Claritin helped immensely. Before I stopped walking outside would lead to sneezing in less than 2 minutes. 3 days later after stopping, I went for a 3 mile walk with 0 sneezes. M 42 5 years

 3  Seasonal Allergies dry mouth, thirsty, I have taken Claritin for seasonal allergies for 2 years as RX. I then took it when it went over the counter. It worked for for my seasonal allergies and kept me from developing more severe symptoms. I also gave it to 2 of my children for several seasons. Unfotunately we noticed a decrease in effectivenes last year and again this spring. We switched to Zytec for my kids but noticed today that my son is having terrible mood changes and temper tantrums. After reviewing the comments on the Zyrteck on this web site I will be going back to Claritin until I can check with the doctor on what other options I have. I would rather have to take the Claritin every 18 hours compared to 24 as my own doctor suggested then see my son the way he has been for the past 2 days. F 44 5 years

 3  year round allergies Extreme Fatigue, Loss of concentration/focus, sleepy during the day..awake at night;dry mouth/excessive thirst/bad taste/occassional dizziness/feeling of heart racing/acidic stomach This worked great in drying up sinuses, but I just realized after reading comments that my symptoms aren't pregnancy,heart problems or in my head!I've been to the doc for heart tests,been to the gyn for pregnancy tests...I'm wondering after 5 yrs of this med if it's all side effects. Every day at 3pm I fall asleep at my job, but then after I get home, I'm wide awake and stay up until 1am. I wake up tired every day. I will try weening off of it, but I have no clue how to control my allergies w/o it. F 39 5 years
