| 2 | Allergies, Asthma | Chest tightness/tight breathing | I tried Claritin because my insurance won't cover Allegra or it's generic anymore since Claritin & Zyrtec are OTC. Claritin should not be used by people who have asthma. It definately makes all those symptoms worse. It does work great for the allergies and dries the sinuses, but has no smooth muscle relaxation affect for the bronchials like Allegra does. It causes too much tension. Insurance Companies need to be aware of this when they make these rediculous decisions to not cover something because there are OTC alternatives! | F | 50 | 1 months | 1/26/2010 | 1 | Allergies | I decided to try taking claritin to help with my allergies but it didn't seem to actually do anything except for make me feel like crap. Started crying could not sleep and felt really depressed and was reading through these comments and saw that I am not the only one this has happened to. I'm really disappointed in Claritin and just threw mine out. I wish people were more aware of this (as side effects/adverse reactions warning is nowhere on the box) and I took regular Claritin. I'm not taking Claritin ever again, far as I'm concerned. | F | 24 | 5 days | 1/14/2010 | 2 | allergies | Drowsiness, fatigue, lack of caring, delayed motor reaction, difficulty controlling emotions, dry mouth | I've never breathed so well in my life and can't remember a time that I felt air expanding into my upper sinuses rather than contracting. However, the side effects were too much for me to continue taking the drug. I tried the 12-hour redi-tabs before bed to alleviate daytime drowsiness, but they cleared my sinuses halfway and left me drowsy for 24 hours. | F | 25 | 2 days | 1/12/2010 | 1 | hayfever and other allergies | Extreme angry depressive moodiness, crying and self-pitying jags | Have taken off and on for the past 5 years or so. Never a problem until the last week. Seemed to go crazy, feel on verge of nervous breakdown, couldn't sleep, angry and weepy, feeling like life had no joy. Could imagine snuffing myself if this went on very long. One of my brothers has had depression because of Claritin. So I think I will be steering clear of this from now on. | F | 55 | 5 years | 1/6/2010 | 1 | dust allergies | I feel drunk, stoned, dry mouth, sleepy even though it said non drowsy | I won't take this again. Its freaking me out the symptoms that I am feeling. I'm a stay at home mom with a three year old son and if I knew that I would be feeling like this I would have never taken this medication. | M | 35 | 1 days | 12/21/2009 | 5 | Allergies | Prescribed for 90 year old mother-in-law. When off of Claritin because there seemed to be no allergy symptoms, she lapsed into abnormally confused and paranoid state - unable to communicate. Claritin was started again and she improved significantly. Has anyone else dealing with someone with dementia experienced this with the use of Claritin? It has happened three or more times, so it seems more than coincidence. | F | 90 | 12/11/2009 | 1 | allergies | all that have been listed on here already. it was a horrible year of my life. It is NOT only Claritin D that causes the moods and other severe side effects. I was on regular Claritin! | To the person that claims that only the Claritin D causes side effects, you are very wrong. Check your facts. | F | 27 | 1 years | 12/8/2009 | 2 | Allergy symptoms | Extreme sore throat, mouth dry, sweat attacks, Insomnia | Worked a treat form the allergy symptoms but not sure if it's worth the hassle with those side effects | F | 28 | 1 days | 12/6/2009 | 3 | Allergies | Please people-post in the right section. If you are taking Claritin D then you are taking the decongestant part of it. That's what the D is and that's the part that makes you freak out, anxiety, anger. I can't take D but it's hard to figure out posts on here when people are posting experiences with Claritin D and not just plain Claritin. Know what the hell your taking and posting on. | All that being said-I don't react well to D at all. Jitterness, bad anger. The regular claritin seems the lesser of evils of Zyrtec and Allegra. | M | 36 | 7 days | 11/19/2009 | 1 | Dr. recommended | Severe dry mouth,anxiety attacks.I can't wait until it wears off.I will never take again or suggest to others.I'm very upset and will tell my Dr. | M | 55 | 1 days | 11/13/2009 | 1 | allergies | Extreme moodiness - mostly feeling unlike myself and depressed. I had feelings like everything was out of my control and felt on the verge of crying for almost two hours. Caused muscle soreness. The first dose I took made me feel extremely out of it and almost zombie-like. I felt as though I was moving in slow motion. | I took Claritin D-12, twice a day for three days to get rid of a horrible runny nose and watery eyes. The allergies cleared but it was not worth feeling horrible. I will not recommend this medicine to anyone. | F | 17 | 3 days | 11/10/2009 | 1 | Allergies | Usually I tak Claratin D 12 hours, as needed but my allergies picked up more over the summer with watery eyes and congested head. The pill helped clear my head and eyes, but I started getting heart palpitations and very stiff joints. I also found myself crying for no reason. Since I have stopped taking it about 5 weeks ago, my joints have stopped aching and the palpitations have reduced but they are still there. | F | 46 | 6 months | 11/2/2009 | 1 | alleriges ie: coughing, sneezing, | temper tantrums, moodiness | Gave this to my son for 2 weeks and he experienced 2 major meltdowns completely out of character for him. These meltdowns were witnessed by other family members who were shocked. He also had woke up at night crying no, or calling for mommy or daddy. He also started coming into our bed at night. | M | 5 | 12 days | 11/2/2009 | 1 | Allergies that just started | Have been a total mess! Thought I was suffering from deppression. I just started taking this about or 5 months ago..I have been so mean and angry twards everyone. Thought I was going nuts. Been crying and sad for nothing. I have never been this way ever..I was really starting to doubt myself. My brests have been sore as hell constantly. I even thought I was pregnant! After seeing this sight I feel soooo much better! I am done taking this forever!!!! | 5 months | F | 29 | 10/26/2009 | 1 | to allay nasal congestion | deep depression, about midway through one dose cycle. I took as directed for adult. | Did not allay nasal congestion, and the side effect of deep depression was enough to make me stop it after one dose cycle. | F | 64 | 1 days | 10/26/2009 | 1 | Multiple allergies and rhinitis | Mood swings, crying, confused behaviour. | I have been having my concerns about claritin and after reading this web site I am convinced. It is not good for children. | M | 8 | 2 months | 10/19/2009 | 1 | sinus infection | Anxiety, dizziness, panic attacks. I went from a normal person to someone afraid to drive/leave the house. | F | 51 | 4 weeks | 10/16/2009 | 2 | Animal dander allergies | I woke the next day, after sleeping almost 10 hours, very dragged out, and mentally confused, foggy, conflicted, angry, depressed. I could tell it had affected me mentally in a negative way. | I bought some Children's Claritin, and took the recommended dose,2 tsp, which is a 5mg dose, taking it around 12:30 pm, and it quickly opened up my lungs and my breathing was much better. Before going to bed last night I took one tsp., around 11pm. Benydryl wipes me out, so I was trying to find an antihistimine that I could take on a regular basis, and thought I would try a mild children's version of Claritin. But this morning I awoke not feeling mentally together at all, and felt angry, depressed, sad, basically very conflicted. I'm stopping it immediately, especially after reading others comments here. | M | 54 | 1 days | 10/15/2009 | 3 | Alergies | I had been taking the drug off and on for years. Up till the past couple years I never noticed side effects. With in the past 6 months I started having panic attacks and anxiety attacks along with irregular heart beats. I first thought it was stress or lack of fluids. Now after seeing this site, I will only use it in an emergency and expect the other symptoms to slowly go away. | M | 44 | 5 years | 10/7/2009 | 1 | allergies | Within 30 minutes of taking my first tablet my body started having involuntary tics, mainly my tongue moving around in and out of my mouth, my head turning to one side, and my arms waving all over the place. I was rushed to be given an injection of something to stop these effects, and told to NEVER take Claritin again. I was never warned about serious side effects at all! | Although my side effects were very rare, things like this should be listed in the information about the medication, so people at least have a choice as to whether to take the medication or not. I have since been told by my new doctor that the side effects I suffered could have been long term, maybe even suffered for the rest of my life. | F | 40 | 1 days | 10/6/2009 | 1 | to control sinuse drainage | I was used to running nearly every day 2-3 miles. I went from that to barely dragging myself out of bed. I had no motivation to do ANYTHING. I seemed to not care about anything all of a sudden. And I have a family to take care of!! I finally pinpointed my sense of fatigue and feeling like I was "lazy" to starting at the time I went on Claritin. (just regular Claritin 10 mg 24 hour)I experienced a TOTAL lack of motivation, depression, fatigue, bloating, weight gain, increased sense of irritability, sense of being in a fog as other reviewers have noted. I also had problems focusing as if I could not get it together, my mind would race from thing to thing. And no matter how much I slept I felt like I was not well rested.I was disappointed since it seemed to really be helping my sinus problems, but it is not worth it. | F | 34 | 30 days | 10/1/2009 | 1 | Allergies | Very vivid dreams. Some heart palpitations/anxiety I think...but not sure. No depression, anger or insomnia. | I have had occasional nights of vivid dreams before, but when I started having them every night I knew that there must be some external catalyst. My daily dosage of one Claritin was the only change to my regimen, so I went to Google and typed in “Claritin dreams” and to my surprise got multiple hits. No more Claritin for me. | M | 57 | 7 days | 9/30/2009 | 3 | sinus congestion/partial occlusion | extream irritability. constant thought of needing claritin. anger outbursts, unstable emotionally, headaches in the mornings, fatigue. feelings of indifference. Food cravings. | helped my sinus for a short time (aprox 1 month) then kept craving claritin and would get SICK extreamly SICK if not taken in a 24 hour period (headaches that made me lay down for hours and only relieved by claritin or 3-4 days without claritin.) | F | 29 | 2 years | 9/23/2009 | 4 | pollen allergies | I'm not certain yet that this is caused by the Claritin. I've taken it without side effects and good efficacy vs. allergies for the last 2 years. However, when I started taking it this Fall allergy season I began experiencing severe aches and pains all over my body. I cannot sleep because of the pain and it affects my work. The aches and pains reduce slightly during the day, but are pretty much constant. | M | 45 | 7 days | 9/22/2009 | 3 | Allergies | My child is 3. He was put on 24hr claritin for children to help with his allergies and to help control asthma. He has always been the sweetest little boy, and I'm not just saying that because he's mine. He's been on it for two and a half weeks, and in those two weeks we've had uncontrollable emotional issues. He is in a private preschool, and has gotten sent home because excessive crying, and cries here at home too while he just seems sad. We gave up our nap time the middle of this summer, he didn't want to sleep so it was a fight. Now, he falls asleep at noon while eating, this is after going to bed at 7 p.m. and waking up at 7:30 a.m.!! OVER 12 hrs of sleep!! Not to mention frequent nose bleeds - sometimes four times a week!! Also, the past three days he has been hitting and pushing other children which has never been a problem. I thought it was just a stage but after finding this site I feel terrible! My poor child has probably been feeling all the emotions you all have desc | Worked great on his allergies, but not worth it!!!! | M | 3 | 18 days | 9/20/2009 | 1 | runny nose, itchy, watery eyes | Racing heart, anxiety, insomnia | I took Clairitin 24 hr at 4pm and it seemed to relieve my runny nose right away. But within an hour of going to bed, I was awake with anxiety and a racing heart. I never have insomnia, so this is abnormal for me. After drinking lots of water, the racing heart has subsided but I feel tired yet wide awake. Clairitin is not for me. | F | 42 | 1 days | 9/20/2009 | 1 | Allergies, regulating ear pressure | I took Claritin 24 hour everyday for 2 weeks to relieve my allergy symptoms which mostly consist of a terrible, constant popping in my ears. It was suggested by my ENT to help this problem and it worked wonders. I had a hysterectomy 6 yrs ago and do occasionally get PMS type symptoms so at first when my breasts became sore and I gained a couple of lbs, I thought nothing of it. By the end of the 2 weeks I was constantly waking at night, the skin on my face was extremely dry, I was loosing hair by the hand fulls, my breasts were so sore I couldn't even stand to have a sheet lay against them and I had gained 10lbs!! No more Claritin for me! | F | 37 | 14 days | 9/18/2009 | 1 | seasonal allergies | ANXIETY,mental fog, nose bleeds. Felt dizzy and light headed. Thought I was losing my mind because I couldn't focus. This drug becomes dangerous the longer you take it. | Went to three doctors and none of them told me to stop taking the claritin. I stopped after finding this sight. I am now on week three of no claritin. I am starting to feel normal again. I can't believe you can buy this drug OTC. | M | 48 | 4 months | 9/10/2009 | 3 | seasonal allergies | Extreme fatigue/exhaustion, intermittent headaches, low energy, depression, anger, frustration, overwhelmed, worried. | I've taken claritin in the past on an as needed basis and it didn't really have much of an effect on my allergies. This season I started taking it about 2 weeks prior to allergy season and that really helped control the symptoms. I have been doing great on it for over a month, and just within the last 2 weeks or so I've started feeling so tired and exhausted despite getting tons of sleep. I just crave my bed, like in the middle of the day. I have no energy. I wake up feeling like I haven't slept at all, and now in the last serveral days I've been feeling very depressed, angry and overwhelmed for no apparent reason. I have no history of depression or anxiety or anything else. I didn't really associate it with the claritin because I've been taking it for so many weeks without a problem. But for the last 2 days I haven't taken the claritin, and I am starting to feel much better. I was thrilled to be expriencing what I thought was no side effects with Claritin (as I had a lot of negative side effects with zytrec). Perhaps the levels in your body continue to increase which is why it took a while for me to feel both the positive and negative effects of the drug. | F | 45 | 40 days | 9/7/2009 | 3 | Fall Allergies | I have taken Claritin and the generics...Rite aid, etc. It does work on the allergy symptom control which can be debiliting, but this site is confirming my suspicions that the drug is contributing to my anger management issues. I have 2 angels for kids that can test patience of course, but this drug lowers all tolerance thresholds. And the constant light-headed feeling gets a little old. I was training for a triathlon this fall, so I can blame the drug for my lack of exercise stamina as well. I will confirm the crazy dream posting as well. Anxiety sucks. | M | 10 days | 9/6/2009 | 4 | allergies | dry mouth and vertigo/occasional dizziness | This stuff works great for my seasonal allergies, but I hate the feeling of vertigo. Benadryl makes me really sleepy and Zyrtec give me migraines - I'm so glad I found some allergy medicine that works for me. | F | 39 | 2 years | 9/2/2009 | 1 | allergies/cough | My son-10 years old, started Claritin for a cough he's had for a few weeks. I noticed soon after starting he started having major temper tantrums and was unable to control his anger. He became very aggressive and unmanageable. He has had episodes of this in the past, but nothing recently. Now I'm wondering if perhaps each episode was during a time that he was on Claritin &/or Singular. I've taken him off the Claritin, and his mood has drastically changed. Coincidence? Who knows, but I think I'll avoid this drug in the future- especially with all the others here who've had similar experiences!! | M | 10 | 2 weeks | 9/2/2009 | 1 | pet and seasonal allergies | INCREDIBLY sore and stiff muscles to the point of not being able to walk. Fatigue that was so bad I would have to lay down and then I'd fall asleep for a couple of hours at a time. Sleeping 10-12 hours a night and still being very tired when I woke up. Shuffling my way out of bed due to the pain and stiffness. Depression and anxiety to the point that I thought I was going crazy. I was crying and getting angry at friends and family so randomly! Made me downright mean. If I hadn't found this site and gotten off this awful drug, I was on my way to therapy very soon! Red eyes that I never even got with my allergies. IBS type symptoms with gas, bloating, and diarrhea. Frequent urination with the feeling that I still had to go right after I went - sometimes painful to go. Severe dehydration. Daily abdominal cramping. PMS was off the charts. Period was painful - barely ever got a little cramp before. Lack of motivation. Went from working out daily to forcing myself to do it half-ass a coup | 10mg a day is an overdose for the average person. When I started this stuff I took it as needed and only had small physical and mental nags that I never connected with the drug. Then I increased it to every and the nags grew but I still didn't make the connection. I decided to take it as prescribed on the box because I thought the nags meant it wasn't working. Taking it every day literally incapacitated me! I went off it a week ago and have noticed a huge improvement in my overall quality of life! My normal physical and mental self is coming back. I guess it takes 10-14 days to leave the system completely. I can't wait till it's gone! A class action lawsuit would be a great idea! I didn't see any of those side effects on the bottle! | F | 27 | 1 years | 8/28/2009 | 1 | allergies-mostly congestion | Claritin D 24hr I was having problems sleeping due to congestion and decided to try this. The first night was great, slept all night w/o stuffiness. Second night, it didn't help at all, so I decided to skip a few days. Took it again after two days and it still didn't help the congestion but I was plagued with constant itching all over my body that night and in the morning I noticed I was having a difficult time with my vision, my right eye would get hazy and unfocused. Later that day, I started to have mild anxiety attacks (I am on anti-anxiety meds and have been fine for years) but did not attribute it to the Claritin. Also, I was extremely moody and angry and figured I must be starting menopause. The next night I took yet another in hopes of getting some sleep. I feel asleep only to be jerked away about 40 minutes later with the sensation of falling. Fell back to sleep and it happened again, and continued to get progressively worse and more frequent to the point that I would just do | NEVER AGAIN! This stuff is TOXIC! | F | 40 | 5 days | 8/21/2009 | 2 | pet allergy / seasonal congestion | agressive behavior, moodiness, whininess, appetite changes, sleep problems, crying outbursts, blatant disobedience | It all started with our son taking Zyrtec on and off as needed for over a year. We thought he was just a high-maintenance strong-willed child. It wasn't until he started taking it daily for a couple weeks straight that he became completely unbearable. We would have honestly sworn the devil had possession over our child, that's the best way I can describe what happened. It wasn't until I found this site that it made me think it was the medicine causing it. I stopped giving it to him, and within a couple days, he was a completely different child. Much easier to manage, more agreeable, and overall happy. I thank whoever created this site, and just wanted to post our story, so maybe someone else who experiences the same thing can learn from our misery! We have since tried Claritin, and after about two straight weeks of using it, it caused the same symptoms. Even after being off it, we gave it to him on an as-needed basis a couple times and the personality change was almost immediate. No more Claritin for him! Now we are on Allegra, time will tell how that fares... | M | 4 | 14 days | 8/13/2009 | 1 | allergies | Right after taken claritin I had vivid nightmares every night. I have never had such bad nightmares before. I also got angry very fast, I had road rage twice and even got out of my car twice and went after the person, I have never done anything like that before, I was a freakin animal on this stuff. I was in the bathroom one day and I was talking to myself and then I stopped when I realized what I was doing, It made me think of all kinds of random things, very scary. I also had some shortness of breath and was tired and headaches. But the bad nightmares and the anger issue was a huge problem. | Claritin should be banned from the shelf. | M | 45 | 10 days | 7/29/2009 | 5 | Seasonal Allergies | None | Great Drug for me and my family. Helps wonderfully with our allergy symptoms. | F | 30 | 5 years | 7/27/2009 | 3 | Seasonal Allergies | At first I liked it because it took care of the allergy symptoms and did not make me tired. But I took it as needed at first - but then found it worked quicker for my allergy symptoms if I took it every day and kept it in my system during the allergy season. However within a week of taking it every day it began to make me feel very, very, very anxious and tense. I felt so tense I kept having to remind myself to take deep breaths. At first I blamed it on hormones, but then realized it was the Claritin. I have stopped taking it. I don't know why the drug company did not list this as one of the possible side effects to begin with. | F | 51 | 30 days | 7/21/2009 | 4 | seasonal allergies | I take Claritin D 12-hour every morning for my allergies. It works great on the allergies if taken EVERY DAY, however, I've noticed some changes in myself over the last few months such as weight gain, anger control issues, and depression. I never thought about the anger being associated w/Claritin until I saw how many other people on this sight have experienced it. I will never take this again! | F | 32 | 1 years | 7/15/2009 | 1 | allergies | I experienced depression. Mild at first then more profound the longer I took it. After sucicidal thoughts I will never take it again and would not recommend it to anyone else. | F | 50 | 7 days | 7/1/2009 | 2 | Allergies | Extremely cold and sweaty feet. Lack of concentration. Insomnia. Fever. Mood swings. Depression. | Fuck Claritin. | M | 10 | 2 days | 6/30/2009 | 4 | Allergies | Perhaps a bit of dehydration, but that's all. | I personally love it. It works better than Zyrtec, and doesn't make me drowsy like Benedryl. However, it doesn't completely take care of my allergy symptoms. | F | 19 | 3 months | 6/23/2009 | 1 | Allergies from cats and outdoors | Blurred Vision, Dizziness, Nausea, Extreme irritability, Angry at everything, LUCID, VIVID NIGHTMARES and INSOMNIA | I would not recommend taking Claritin regularly which is what I have been doing. It has made me extremely irritable and unable to get a good nights' sleep - no matter how long I sleep for I'm always tired. I'm also taking a Pychiatric medication (Lamictal), and I think that Claritin reacts poorly with it. So those of you taking psychiatric meds should probably consult your doctor about the use of claritin first. | M | 22 | 30 days | 6/21/2009 | 4 | Eustacian tubes, insect bites | Dehydration/dry mouth, dizziness/lightheadedness on standing up, slight blurring of peripheral vision | I took the generic version for eustacian tube dysfunction (in conjunction with generic Flonase) a while ago, and now I am taking it to reduce the itchiness from some insect bites. The dehydration can be headed off by drinking a lot of water, and the other side effects are mild and a small price to pay for not having to be itchy all day. I would say, from my experience, that Claritin is great when you have just spent a weekend in the woods getting eaten alive by bugs. | F | 23 | 30 days | 6/18/2009 | 1 | Yes | Anger, anger, anger, frustration, and lack of concentration. I became a complete monster and was even about to call a therapist. I ran out of Claritin and immediately noticed a change in my demeanor (for the better). I'd rather sneeze 100 times daily and walk around with puffy eyes than take that stuff again! If you can afford it, I advise trying acupuncture. After a series of treatments, it resolves your allergies forever! | It sucks! | F | 26 | 2 months | 6/18/2009 | 2 | For my 4 yr old son | My son became very uncontrollable with many outburst and tantrums daily. He would have violent anger attacks on me and I was beginning to feel like a horrible parent that didn't know what to do for my child. We had been giving him claritin for 2 months and happen to forget to give it to him a couple nites in a row and we seen a drastic change in behavior. He was back to himself, loving and fun. | Although it worked great for his allergies I will not give it to him again. | M | 4 | 2 months | 6/15/2009 | 1 | Allergies | I thought It was the change of life or something(I'm 42). I had this anger over the last week or two that NEVER subsided. I felt like I wanted to cry, felt overwhelmed and depressed. Not to say I have not occasionaly felt this way, but something was wrong...and the fatigue, I'd wake up tired. Then I thought, the only thing different I've been doing is taking Claritin. I don't know for sure if these symptoms weren't hormones, but the correlation is too coincidental. | BUT, Claritin works great on my allergies! | F | 42 | 2 weeks | 6/13/2009 | 3 | allergies caused sinus infections | dizziness, headaches, insomnia, stomach pains, saw bright spots, anxiety, anger for no reason, irritability, weight gain, racing heartbeat, inability to focus | The drug helped my allergies but after 6 months of perplexing side effects I will never take it again. The anger and insomnia were the worst. Everyone reacts differently with medication--thank goodness for this site. I thought I was going crazy! | F | 37 | 6 months | 6/11/2009 | 1 | Allergies | My 22 month old daughter became very angry, whiny, and experienced nightmares beginning on the 1st day of use. I wasn't sure it was the Claritin (although I suspected) until I found this site. The Dr. told me specifically that there were no side effects whatsoever. She took the medicine for 3 days and was miserable! Today was her first day off of it and I have my happy loving child again. I would NOT RECOMMEND! | They need to come clean about the side effects. | F | 1 | 3 days | 6/11/2009 | 3 | General Pollen Allergies | Moodiness, irritability, fatigue all stemming from general depression. | First of all, the only way this stuff works for me is if I take one at night then one in the morning effectively giving me 10-20Mg of Loritidine in my system at a time. Lab studies have shown this is okay to do on a phyisical basis. That being said, I knew something was up because I had this issue LAST YEAR with Zyrtec. The prolonged use of Citirizine was causing general depression within me to the point where I didn't really care about much and about halfway through the day I would cease normal mental processes (Think fuzzy brain). I'm doing nearly the same thing this time around with Loritidine. Changes: I'm less fuzzy but am really tired even though my routine hasn't changed in over a year and I'm slightly more irritable. Claritin has definatly helped me stifle my allergies though. I would recommend taking it on a short term basis of less than 7 days at a time. | M | 23 | 1.5 months | 6/10/2009 | 1 | Allergies | Insomnia. Oddly I was taking it because I kept waking up at night congested and hard to breath. The insomnia was amazing. I just couldn't sleep. I'd sleep an hour or two a night. This went on for a month. The other primary side effect is anger. I became very temperamental and angry about everything. I stopped taking it because it stopped working, and that's how I figured out the insomnia. I'd known about the anger and was accepting of it to be able to breath. I have also experienced irregular bowel movements, but I cannot concretely link this to the Claritin yet. I am on no other medication. | I think it works fine for many people and you should try it yourself, don't not take it solely on account of my experience. I've taken this drug every allergy season for 4-5 years. This past time it was 90 consecutive days. I take the 24 hour version, the 12 hour version I find does not alleviate symptoms as well. I take exclusively the brand name, I have tried Costco and Target brand generics and they do not work as well. | M | 35 | 90 days | 6/8/2009 | 1 | allergies | I took Claritin last night and this morning I woke up seriously depressed. I noticed some suicidal thoughts before going to bed. I also awoke with some slight ringing in my ears and I just feel really fatigued. | I took Claritin b/c I have interstitial cystitis (possible flare due to allergies) along with multiple allergies to things I probably don't even know about along with those I do. I had allergy shots as a kid and take flonase. I tried Zyrtec but had a rash from that (?). I also think I'm allergic to my dog. I have a history of depression and anxiety. I was pretty stable for about 4 or 5 days before I took the Claritin and my mood switched drastically from when I took it and when I woke up. It could be a coincidence but this is scary. I don't want to chance taking another dose and will stop this and see how I am mood wise tomorrow. I'm glad there is this site to see that it may be the med. I don't need more help with depression, I can get that on my own. | F | 36 | 1 days | 6/4/2009 | 1 | Allergies | My 22month old has been coughing, runny nose, sneezing and everything else you can think of for allergies for the past 3 weeks. We started with Benadryl and only seemed to work at night and not during the day. I talked with our Pediatrician and she recommended half a dose of children's Claritin before bed. We gave it to him at 7:30pm and he was bouncing off the walls for 3 hours. Then we gave it to him again last night before bed and he woke up around 11:00pm screaming uncontrollably and saying NO NO NO. He was hiting, screaming, kicking, and acting like something was after him. We brought him back to bed with us and sure enough he woke up several more times screaming. He has not been himself today. When I did some researchand found this website I couldn't believe some of the things I was reading. I HATE CLARITIN and will never recommend it for children. | This is an awful over the counter drug and should not be recommended for kids. Claritin has awful side affects and it brings out a nasty personality in your child you never want to see. | M | 2 | 2 days | 6/4/2009 | 2 | Allergies | Very angy 4 year old. Normally the easiest kid. Hitting, throwing, crying. He seems miserable...poor little guy. But what to do??? Zyrtec does not sound much better....it did help the allergies, but at what cost??? | M | 4 | 7 days | 5/30/2009 | 1 | Allergies | Intense anxiety. I am not an anxious person. I have pursuits and a job that require the ability to stay calm and rationalize through hazardous situations. After taking one dose of 24hr Claritin I find I am awake in the middle of the night because I am anxious and worried about choking. Completely irrational yet I cannot keep the thought out of my mind. I am watching infomercials because they are bland enough to not make me think of other topics and helping me stay distracted from my own thoughts. Tried to watch a video of a hobby(scuba) and had to turn it off because I couldn't help thinking that it was too dangerous and maybe I should quit! This is nuts! They don't warn you about this. On top of it all - no effect on my allergies | DO NOT USE | M | 37 | 1 times | 5/25/2009 | 1 | Allergies | A sense of impending doom, didn't care about anyone or anything, unusual angry outbursts, changes in personality, tiredness. | At best, I didn't feel quite like myself. At worst, I felt like a psychopath on this stuff. I would recommend that anyone taking this medication should be carefully monitored for any changes in thoughts or moods. | M | 27 | 1 months | 5/23/2009 | 2 | allergies | Extremely moody, tired, lethargic, and hungry | Extremely sleepy no matter how much sleep I get! Very hungry,and eating uncontrollably. I'm usually in the gym almost daily and haven't been able to go in 4 days since I started taking this medicine. Plus I've been getting easily annoyed by every little thing! I can't take this medicine anymore. But it actually did help my allergies, just not worth it to me..... | F | 25 | 4 days | 5/21/2009 | 1 | Seasonal Allergies | With the 24 hour Claritin I got very vivid, realistic nightmares, I would wake up screaming. I have never had nightmares before. With the Claritin-D I had a racing heart beat--scared the heck out of me. Immediately went to the doctor and he determined it was the Claritin-D and took me off it. | F | 49 | 5/20/2009 | 3 | allergies, sinus headaches. | now that i found this site, i do believe i've experienced anxiety, moodiness, scary dreams...paranoia...and a runny/dry nose. | well, now that i've seen this site, i was gonna take zyrtec and now i'm not so sure about meds anymore. claritin just hasn't been able to help my allergies too much. i can say though that neti pots work well. i'm on claritin right now so maybe i'm not making much sense. haha. | 26 | 2 years | 5/12/2009 | 1 | I'm speaking for my daugheter, 15 yrs. old. We thought she was going to die. Doctors said she had an "Adverse reaction to Claritin". We are still desperate and feel uncertain about her future. On April 30, 2009, she took one pill of Clarit reditab 24 hr. 3 hours later she started with mild side effects,such as unfocus vision, nervousnes, went to bed. Her dr. saw her the next morning and said it was side affects, "no more claritin"; Friday afternoon, May 2nd, she started with moderate shaking in her back. I took her to emergency room. She was shaking more, from her neck to abdomen. Benadril didn't calm her down, Ativan didn't help. They just knocked her down. We were sent home and told to wait. Back to ER on Saturday, May 3rd. Condition got worst on Sunday, May 4th back to ER, finally they ordered CT scan and blood test, said she was ok, but still shaking, back home and told to wait!!! My daughter went through a traummatic situation. Her adverse side eff | Claritin should make people aware of the "adverse side effects", don't hide them. The box doesn't mention anything!!!!!!! Shame on claritin. Let's speak up!!!! Please report them to Food and Drug Administration | F | 15 | 1 days | 5/10/2009 | 1 | allergies | Extreme fatigue, muscle aches, dizzy when I bend over and get up fast, mettalic taste in mouth, irritable, Tired no matter how much sleep I get, | M | 43 | 5 days | 5/10/2009 | 2 | Hives. | It works really well for hives. I used to take Benadryl but it made me so stoned I could barely function. I started taking a generic version of Claritin when I moved to WA from Los Angeles, because all the pollen was making it worse. However, I've been super bitchy and mean basically since I got here. I've also been more depressed than I've ever been, and borderline suicidal. I have a history of mild depression and anxiety, so I figured it was moving and other life changes but after reading all these comments I think I prefer being stoned to being awful to people I care about. | Try it but pay attention to how you feel emotionally. It works really well for some people, and again, it completely controlled my hives. It just made me a psycho-hose beast. | F | 25 | 3 years | 5/8/2009 | 2 | Allergies | Vertigo, dizziness, headache and very drowsy, even though I was taking the Non-Drowsy version. | I was taking the Non-Drowsy Claritin RediTabs. | F | 35 | 1 days | 5/7/2009 | 3 | allergies | stomach pain, anxiety, sore joints. | did help with allergies but my allergies are mild. not really worth it in my case. | M | 32 | 1 weeks | 5/6/2009 | 1 | allergies | broke out into hives, nausia, adbominal cramping, allergies became much worse: my eyes are swollen and hurt very bad, my nose if very dry | F | 30 | 2 days | 5/5/2009 | 3 | Very realistic NIGHTMARES. | I have seasonal allergies and was prescribed this drug by my dr. Allergy-wise the drug does its job, but after awhile of taking it I noticed I was having very vivid, and disturbing nightmares. I noticed when I had these nightmares they were on days I would take Claritin. When I stopped taking the drug, the nightmares stopped as well. I am currently trying Allegra to see if it works any better. | F | 1 months | 5/4/2009 | 1 | Seasonal Allergies | Dry Mouth, Anxiety, Irritability, Hot Flashes, Depression, Manic thinking | I do not think that Claritin helped my allergy symptoms enough for me to continue taking this medication. The side affects were terrible and made me extremely hormonal and feel as if I was constantly either angry or sad and also caused me to experience hot flashes. I would consider taking Flonase or something more local rather than suffer from the strange side affects. | F | 21 | 2 months | 5/3/2009 | 1 | allergies | A few days ago I tried Claritin D and on 5/1/09 I woke up 2am with tremors as if I were freezing. I closed my window but realized I did not feel cold but could not stop shaking,and became nausea and unable to get my words out stuttering (which has never happened). I managed to call a family member they could not understand me on the phone but came and rushed me to the hospital. The doctor first thought it was an severe anxiety attack however I was found to be having multiple seizures. I am a healthy adult other than the season allergies. My family informed him the only thing I had took was the claritn D for the 1st time. Tonic Clonic Seizures as a result of Claritin D is what the emergency doctor called it! This should be BANNED!!!! it's day #two and I am still have stuttering and minor convulsion they gave me RX Ativan and to now follow up with a neurologist. I was and still am feeling scared also slight tremors. Help....how can I flush this out of my system? I've been drinking plenty | F | 41 | 3 days | 5/2/2009 | 2 | allergies | dizziness, light headedness | took it (the generic 24hr) tonight for the first time. within about 1/2 hour I began feeling light headed and dizzy-- which is very disturbing... I will certainly not be taking this again... | M | 36 | 1 days | 5/1/2009 | 2 | allergies | My 6-year old son has been taking Claritin for 10 days. He has been agitated, angry and depressed. I'm just now starting to put it all together and I'm horrified that I gave this to him! I know Claritin works well for some people, but watch for these side effects!! | M | 6 | 10 days | 4/27/2009 | 3 | Spring Allergies | lightheaded, extreme anxiety/panic attacks (something I've never experienced before), mild/moderate depression (something I rarely have), shortness of breath (think anxiety related) | I took the generic form for about 2 months but didn't make the connection until today while researching if it was possible that my sudden onset of anxiety could be caused by this medication. I ran across this site and about 95% of what everyone else has experienced, I have also experienced to some degree. I now will only take this if my allergies are more than miserable. I did have relief from my allergies. | F | 34 | 2 months | 4/24/2009 | 4 | Seasonal Allergies | During the three days that I took Claritin I didn't experience any strange side effects, HOWEVER, on the fourth day I decided NOT to take it, and wow... I seriously think this drug should be banned. I started getting dizzy-like symptoms, more like Vertigo, but oddly, my allergy symptoms were gone. It's been the third week off of Claritin, and I still have this terrible off-balance feeling. For a few days it felt like gravity was pushing me backwards, so I felt like I had to lean backwards all the time. Now it feels like the ground is springy or something, almost like when you've been on a boat for a really long time, and then you get off and you still feel like you're floating on water. Yeah... it's really strange. I'm getting very worried so my doc ordered a CT scan to see if there's anything wrong with my brain. I seriously hope not. I vow never to take Claritin again, oh, and I think it triggered my asthma as well, which I haven't had since I was a kid. I HATE CLARITIN!!! | F | 21 | 3 days | 4/23/2009 | 1 | allergies | I took one Clartin. The next day I had this feeling of impending doom, extreme depression. I stayed in bed all day crying with thoughts of suicide. I remained in the condition for 3-4 days and am just "coming around". I think this drug should be outlawed. | F | 46 | 1 days | 4/23/2009 | 2 | hay fever | dizziness, disorientation, mental agitation, nightmares | First few days it worked very well. Then I had a bad dream and woke up disoriented, panicky. Tried another half-dose a few days later; side effects were even worse. I'm not going to touch it again. | M | 53 | 7 days | 4/19/2009 | 2 | Sneezing | After reading all these other comments, I now realize that the rash on my face that hasn't gone away for a year, as well as the unexplained 10 pound gain of water retention, swelling of the face, and my lack of sex drive may all be related to it. I thought these were all seperate problems affecting me for various unexplained reasons. I stopped taking the Claritin about 4 months ago, but still have rash and low sex drive. (Lost the 10 pound of water in days and face swelling!) Will the rash ever go away? | The product always helped my alergies, and after an ear operation, I even found that doubling the perscription kept my ears and sinuses dry and normal. Now years later, after taking it daily, I think these other issues with my health may be related. Both my dermotologist and internal medical doctor can't explain the rash on my cheek, and I am worried it may never go away, and that I may not regain my sex drive, even after I stopped taking it. Is that possible? | M | 42 | 3 years | 4/19/2009 | 2 | Allergy | I had INTENSE anxiety. Mild depression... scattered thinking, sometimes found myself doing very strange things for no reason. I have had anxiety disorders in the past but have managed to find coping mechanisms and medicines to alleviate them. This med sent them OVERDRIVE. This is the second time Ive tried this drug and had this reaction (one month ago had the same experience, but though it might have just been coincidence) | I would suggest that if you are prone to anxiety you think very carefully about the dosage you take. Perhaps experiment with half or maybe even less than half of a pill before going all the way in. About 20 hours since i took it, and the negative effects are still there but wearing off. | M | 25 | 1 days | 4/16/2009 | 2 | Allergies | This is not the D Version! Many ratings on here I think include the D which is pseudoephedrine. I cannot take the D for it makes me not necessarily have more anxiety but very irritable, angry and borderline psychotic. :) Claritin worked for my allergies but completely zapped my libido and made me not be able to go south of the border. I decided to give Clarinex a try and it made me feel real uneasy and unsettled and increased my anxiety level(I do have an anxiety disorder). | Tried Claritin and Clarinex-helped allergies but made me feel uneasy, unsettled, and made me not be able to perform in bed. Zyrtec worked well within an hour but it does make you a little sleepy. I did take allegra 180mg in the past but gave me a headache so I am going to try taking it again at a lower dose of 60mg twice per day and see if that helps. If no success with that I may give zyrtec another try and see if the drowsiness goes away. So not much luck so far. | M | 36 | 4 days | 4/9/2009 | 2 | Allergies | I was frequently developing sinus infections due to allergies. My doctor recommended I take Flonase and Claritin-D to knock it out of my system. The first 4 days, seemed relatively o.k. I could definitely breathe better (but did feel a little anxious and slightly dizzy). On the 5th night, I started having hallucinations that my husband was standing accross the dark bedroom waving at me. I looked next to me, and he was there sound asleep. I had to shake my head and rub me eyes several times before my vision and head became clear. I was so paranoid, I wouldn't get out of bed for any reason until the sun came up. I don't have any evidence that this was caused by Claritin-D (Flonase??), but I have never experienced any feeling like this before. | F | 28 | 5 days | 4/8/2009 | 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 | 4/1/2009 | 2 | Allergies | No side affects. It just did absolutely nothing to help with my allergies. | F | 42 | 1 days | 3/31/2009 | 1 | seasonal allergies | Depression, Terrible Mood, Anxiety...i could go on and on. | I will NEVER take this again. | M | 30 | 1 days | 3/28/2009 | 2 | For seasonal allergies; itching etc | I took a 10 mg, non-drowsy generic drugstore brand of Claritin, manufactured by the same company that makes the brand name. I've taken it 3 times, always for itching, nasal congestion and watery eyes related to seasonal allergies. Each time, after about an hour, I got a headache/earache over the left side of my head. It was bad enough that I lay down until I fell asleep. I rarely get headaches (maybe one or two a year) ... and never bad enough that I stop whatever I'm doing to take a nap. The headaches were so alike and in such a specific part of my head that I can only attribute them to the Claritin since I've never had anything like them except when I've taken Claritin. | The medication did help my allergy symptoms, but the headache wasn't worth the symptom relief. | F | 52 | 3 times | 3/22/2009 | 2 | During Allergy Shots | Panic Attacks (anxiety), sudden onset of depression, mood swings, dizziness, very dry sinuses, ringing in the ears. | My doctor gave me samples of this to take to control the side effects of my allergy shots. I would rather take those than the side effects from Loratidine. It is effective in stopping the red hot welts I usually get with the shots. I just wish I wouldnt feel like I'm panicked or about to cry for no reason. I also was nervous driving back home because of the dizziness. | F | 24 | 3 days | 3/13/2009 | 2 | congestion, headaches, swollen | I experienced drowsiness, even though it said non drowsy and I was taking the 12hr Claritin D. My personality was down as I was so out of it. On the third day, today, I woke up at 6am with anxiety. Throughout the day the anxiety increased until I was very short of breath and sweating with a pounding heartbeat. Luckily, my heartbeat and respiration are returning to normal, but it has been 3-4 hours and I took Kava kava to treat my anxiety. | It did help my congestion, and I think some of the swelling went down in my eyes and face (I swell with environmental allergies), but I was completely lackluster until I began quietly freaking out. It's really not a lot of fun and it took up a lot of my study time. | F | 21 | 3 days | 3/10/2009 | 2 | coughing, sneezing, itching | I will preface this by saying I am not yet positive that the Claritin is directly impacting my son's behavior. 2 weeks ago, my 6 year old was started on Zyrtec. Then a week ago, his pediatrician suggested Claritin & we switched to that. For the past week, my son has had increased difficulty in school with his behavior, activity, impulse control, and mood (easily upset, hard to control his emotions). The mood issue is particularly concerning. While he has his active, impulsive days sometimes, he hasn't been having tantrums or whining at school at all for some time. | I am going to stop the medicine and see if he has an improvement in behavior. My son may have undiagnosed ADHD and/or some sensory issues (we've recently made a referral for an evaluation with a developmental pediatrician), so it may just be that he's more sensitive to the med than the average child. I just wanted to post this to make parents aware (especially if their child is active, sensitive, etc.) that if there is a change in behavior that coincides with the start of this medication, that they might want to consider stopping the Claritin. I did call Claritin's customer service #, and 3 of the 4 common side effects for children (listed to me by the customer service rep) include nervousness, fatigue, and hyperactivity | M | 6 | 8 days | 3/4/2009 | 1 | allergies,fluid in ear,lightheaded | Paranoia,extreme fatigue,nightmares,very moody. Can't "let things go",anxiety,depression,irritability. I did not think it was Claritin until I read everyone having the same symptoms as me. The sniffles went away but lightheadedness is just as bad if not worse. | I am a recovering alcoholic/ addict with 24 yrs of recovery and this stuff is horrid. I could not believe the change in my attitude. This is unacceptable for me. I have probably lost several friends from my actions while on this drug. I will live with my symptoms before I take Claritin again. | M | 48 | 7 days | 3/4/2009 | 1 | Seasonal allergy symptoms | My biggest complaint is a dry cotton mouth. After two weeks, I noticed I was constantly sucking or chewing on my tongue or the inside of my mouth! I increased my water intake, but to no avail. Taking a whole dose once a day made my mind race and turned me into a crazy woman. I couldn't think straight. So I tried taking a half tablet twice a day. I did that for two weeks. I, too, experienced sudden flashes of anger which came out of nowhere. They were fleeting (and didn't happen every day) but they were frightening. Shortness of breath slowed me down. My husband wasn't thrilled with my loss of libido. I do have one positive thing to say about it -- it DID help with clarity -- my brain didn't feel so fuzzy when I was on it -- but it's not worth the tongue-chewing, dry mouth! I stopped taking it two days ago and got my energy and libido back. My husband is smiling :-) I'm still sucking my tongue, though. It's quite annoying. | F | 55 | 1 months | 3/4/2009 | 1 | extreme post nasal drib | Blocked Eustachian tube, dizziness, painful headaches in the morning but they go away pretty fast after I get up and take a Claritin. Increased blood pressure. Sometimes ringing ears. | After 6 months of taking the daily pill and a benedril at night, I didn’t take them for a couple days and my right Eustachian tube blocked – voices sounded like they were far away down a tunnel, I thought it was excess wax. I went to the doctor and was told that I didn’t have excess wax, the problem was in my inner ear and something to do with a reverse vacuum and to take Claritin and it would be fixed! Doctors know this fixes the problem but don’t tell you that going off of it can cause the problem! But now whenever I try to stop taking Claritin in just one day my ear clogs up again and this doesn’t work for my job that includes a lot of meetings! I am going to try taking the 12 hr kind once a day to slowly get off of it! Benadryl may make me sleepy but coffee helps counteract it and I don’t have side effects when I don’t take it. I don’t take any other medications daily and don’t want to be addicted to Claritin either. | F | 53 | 6 months | 3/2/2009 | 1 | for a runny nose | every day i took the drug i've gotten a bad bloody nose (im 20 and haven't had a bloody nose since i was 11) | i do not plan on taking the drug any more I'd rather have a runny nose than a bloody nose | F | 20 | 2 days | 2/18/2009 | 1 | Allergies, likely tree pollen | Foggy head, inability to complete fairly simple tasks, sweating, not feeling like myself. Possibly also caused bouts of short temper and snapping at my family. | Cleared my sinuses but did not help with coughing. Spending time in a retail store with superb a/c and ventilation did a better job of stopping symptoms temporarily than Claritin did. Agree with other reviewers this drug should not be OTC but SHOULD require Rx. There should be a very clear warning about possibility of 'foggy head', and depressive symptoms in particular. IT IS IRRESPONSIBLE TO MARKET THIS DRUG AS NON-DROWSY as it easily leads the consumer to believe there is little danger of not being able to function normally at home and at work, NOT TO MENTION DRIVING A VEHICLE. BE VERY CAUTIOUS WHEN TAKING THIS DRUG. I would start taking it over the weekend or when you can stay home for a couple of days to be able to asses what side effects you may experience. Also, if you have family, it would be good to have another grownup around to care for the kids in case you feel foggy or have depressive symptoms. DO NOT GIVE CLARITIN TO KIDS WITHOUT CHECKING WITH YOUR DOCTOR FIRST. My | F | 39 | 4 days | 2/14/2009 | 3 | allergies/sinus | Bad, vivid nightmares, night sweats (soaking sheets), extreme hot flashes on lower back, fatigue | It works, but after taking it for a while these other symptoms popped up. Now I only take it when I have to. Just developed allergies last year. | F | 26 | 8 months | 2/10/2009 | 1 | Allergies | My 9 year old son has been having very vivid nightmares for the last twelve days. I've gone through a laundry list of things that could be causing this. The only thing I could link it to is that he was changed from Allegra to generic Claritin. I've put a call into his doctor and then found this website. Wow! The stuff is going in the trash as far as I'm concerned. | M | 9 | 12 days | 2/10/2009 | 1 | Stuffy nose | Shortness of breath, wheezing | First time giving this medication to my 9 year old who is not on any other medications-- within an hour she had marked shortness of breath and wheezing. Will never use again | F | 1 days | 2/7/2009 | 1 | control runny nose in the mornings | Extremities and face became red, itchy on two occasions. The first time was a week ago, lasted ten minutes, did not connect feeling to taking Claritan at that time. An hour ago took Claritan, as I have done daily for the last two weeks, and extremities and face became quite red, itchy. No shortness of breath at all. Emergency doctor's exchange nurse recommended taking Benadril due to non-severity of reaction, ie. no shortness of breath, no racing heart, etc. | M | 84 | 14 days | 2/3/2009 | 2 | Sinus/Allergies | I'm not sure my daughter is reacting to this med, but after reading the posts, I think she might be. She has always had problems with one girl at school, but those problems have magnified since she started on Claritin 8 days ago. Also, her attitude at school has been terrible--she has refused to participate in group projects, and she is moody and doesn't have any patience! She already has anxiety, and I think this might be really messing with her. Things have been getting worse at home too. | F | 9 | 8 days | 1/28/2009 | 3 | Cedar fever, watery itchy eyes,nose | Racing heart, dizziness, confusion, tight head | This week is the first time I've tried Claritin D. It worked so well for my cedar fever (itchy watery eyes, runny nose, sore throat, etc...) that I started taking it every morning. This is probably the 5th or 6th time I've taken it and it may be the last. All of the sudden my heart started racing, I got dizzy and my head got really tight. I think my heart has slowed a bit, but my head still feels very strange. I'm at work and it's making it very difficult to get things done. I am not sure whether the relief from the allergies is worth this feeling. I will likely try the 12 hour instead of the 24 hour next time. | F | 29 | 6 days | 1/23/2009 | 1 | Allergies | My son 2 and a half, became VERY irritable, actually broke out with a rash on his cheeks, and would wake up screamin gin the middle of the night, shouting no!!!! | My daughter found this site and thanks God, as it really helped us put two and two together, I was racking my brain trying to figure out what made the change. the only thing we cam eup with was the Claitin a so she reearched this site and low and behold found our answers. He will NEVER take this med again! | M | 2 | 3 days | 1/10/2009 | 5 | Allergies both outdoors and indoors | None | I too have never had any side effects when taking Claritin. I don't understand the nightmare issues but this might be because of a fear of medicine or something like that. Has never happened to me and I have sensitivities to alot of prescription drugs. Claritan works. If your miserable with allergies I highly recommend it. | F | 44 | 1 years | 1/2/2009 | 3 | Allergies | I took half a generic Claritin tablet and within an hour felt like I was drunk. I'd rather have a stuffy nose! | F | 52 | 1 days | 12/31/2008 | 1 | NIGHTMARES! | I took Claritin for the first time yesterday. I took it right after lunch and it seemed to really clear up most of my symptoms. I didn't feel strange or anything like I do sometimes when I take allergy medicines. HOWEVER, I had the most horrific, vivid, terrifying nightmares I have ever had in my 24 years of living! I can't remember the last time I ever had a nightmare, so I know it had to of been caused from this medicine. Reading the other comments confirmed that I am not the only person that has experienced this. Because of the nightmares, I will NEVER EVER take Claritin again. It was just that bad. | F | 24 | 1 days | 12/30/2008 |
