 1  fluid in ears, allergies anxiety, bad dreams, loss of concentration I took the first dose before bedtime and within an hour started experiencing waves of anxiety. Didn't think much of it, due to I've had some anxiety in the past. I also had bad dreams that night and some anxiety upon waking up, but was okay the rest of the day. Took a second dose before bedtime the second night, and experienced the bad dreams again. When I woke up the next morning, TERRIBLE anxiety. Couldn't go to work, and didn't want to be alone. I struggled to remember what day it was. Will not take again. F 39 2 days

 4  allergies Wondering if it causes, heat flashes, night sweats??? Thought I was starting menopause, but all of my adult kids,ages 27,28,29, have these symptoms too, as we all started Clartin at the exact same time . Shakiness. But it has worked! I was sneezing and had red itchy eyes that was out of control. We have a cotton wood tree that is SNOWING cotton now and it will be this way for a few weeks...All of my allergy symptoms have stopped. I have turned up the air condition and been sure to not have an empty stomach so the side effects have leveled off. F 51 2 weeks

 3  Seasonal allergies bad headache, ringing in my ears, sharp stomach pains like ulcer pains, light heartburn, increased anxiety (this seems odd, but I think its really due to the clariton) worked very well on the allergy symptoms. Now I take one 24 hr pill every other day to cut down on the ear ringing, sharp stomach pains and bad headaches but still get rid of some of the bad allergy symptoms. Its hard to measure how much the anxiety is changed by taking less. M 42 2 weeks

 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

 3  Allergic sinus congestion Dizziness and vertigo, constant irregular heartbeats, anxiety, fatigue, and irritability. I began taking Claritin in the A.M. until dizziness became a problem, then I took at bedtime. The symptoms slowly increased since I started taking the medicine on a daily basis about 5 months ago. Since then, my heartbeats have become increasingly irregular to the point that it is frightening. The anxiety and irritability may be from fatigue and concern over the heart issues. I am stopping the medicine today and will post another message in a few days if the symptoms clear up. F 47 5 months

 1  Flu-like symptoms Severe dry mouth. I took one tablet 3 days ago. My mouth and throat are so dry that I cannot eat, talk or sleep easily. Dry mouth occurred within hours after taking the one tablet. The discomfort of dry mouth is unbearable. I would much rather be coughing and sneezing. F 44 1 days

 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

 1  Dermatographia Night Terrors, Anxiety, Severe Depression, Suicidal Thoughts, Irregular Sleep, Palpitations. I'm bipolar and had a severe reaction to this medication. I felt lost and severely depressed, more so than what I'm used to and had no idea why or what was happening. I found myself confused and anxious, and experienced panic attacks and night terrors in my sleep with palpitations. I figured it out when I woke up shouting and wildly throwing punches. I can't even recall the last time I had a regular nightmare so this was very disturbing. I had no manic moods or any mood swings while on Claritin, only severe depression and anxiety. I stopped taking this as soon as I realized these were side effects of the drug, and within 48 hours it all stopped. I was so relieved and yet my doctor seemed to not believe me. Awful. M 26 6 weeks

 1  Allergies erratic heart beat, high anxiety, severe dry mouth, no appetite, dizziness, lack of concentration, cold sweats, chills I felt like I was having narcotic withdrawls! I wanted to jump out of my skin.....My allergies were cleared up, but I felt like a junkie trying to kick heroin!!! I would rather have a runny nose rather than going through that again!!!!

 1  seasonal allergies dry mouth, impotence, problems urinating I have heard it takes a while to get into your system and I started to notice my dry mouth within a couple of weeks and as time went on it got worse. Then the urination problems started and then the erectile disorders. Some people on here put on the same stuff so i'm relieved something isn't really wrong with me. I guess impotence is a rare side effect but it can happen and that was the last straw for me. M 17 2 months

 1  cough DO NOT GIVE TO CHILDREN!! hallucinations of bugs trying to kill her, NIGHT TERRORS, irritability!!!!! My daughter would wake up throughout the night screaming, crying, telling us bugs were trying to kill her. It was awful. I realized this started a week ago when she started taking Claritin, its the Loratadine as he took the generic brand also. NOT WORTH THE RISKS FOR SMALL CHILDREN!!!!!!!!!1 F 2 7 days

 1  chronic sinusitus (most of my life) ANXIETY, NERVOUSNESS, INSOMNIA, IRRITABILTY (started mild, evolved into constant inner rage), DEPRESSION, FEELINGS THAT NO ONE UNDERSTOOD ME, LOW LIBIDO. I am normally a happy, smiling, relaxed person who sleeps easily and laughs a lot. I even laughed at drug commercials where the narrator rattles of a gazillion side effects. Laugh no more! On Claritin I was okay at first - a little anxious & nervous, but no big deal. It turned into constant anxiety, a desire to bicker over every little thing, anger at everyone & everything, and waves of despondency. I could only sleep a couple hours at a time, but I was soooo tired I could barely stand it! My poor husband, I was a walking whackjob! Plus, I had no sex drive at all - Zero, zilch! After approx 1 month of taking Claritin daily, I stopped. It's been 10 days now, and I feel back to my normal self. I have my sinus problems again, of course, but that was expected. Claritin is the only explanation I can find to why I felt and acted differently for that month timeframe. For those people who think these side effects are simply imagined - I'm happy you are not experiencing what I did when I was on Claritin. F 43 30 days

 2  allergies, sensitivities Bloating, nausea, indigestion, and couldn't stop burping after every meal. Side effect fever (100 degrees) and flu symptoms and throat infection. I finally realized it was the Claritin and saw there are a lot of people with the same reactions listed here. Allegra and Zyrtec worked better for me. F 41 8 months

 1  Allergys VERY aggressive behavior! Sweating, anxious. I have a developmentally disabled son with severe speech apraxia, he is usually a pretty even tempered boy of 14. After takeing Claritin for about 5 days he was sent to the nurse at school because he was soaking wet from sweat, she took his BP & temp. which were normal, she thought maybe low blood sugar so gave him juice. (he has never had low blood sugar before.) She called me, the only thing different I could think of was the Claritin. Funny thing is the box does not list any of the allergic reactions it might cause, just to call your Dr. if you have any! The next morning he woke up being very aggressive and mean. But sense he has verry little speech, he can not tell me what is going on. I quit giveing him Claritin and by the next day he was fine! I will NEVER give this to him again! M 14 5 days

 4  allergies none The rest of you who say you felt paranoia or anxious or suicidal are gay. I 'm sure you all feel that with any medication you use. You probably feel that way if you try a new food you've never had before. Get over it! M 28 1 years

 5  Hay fever w severe headaches None - until I read this web site and discovered all the things I might blame on Claritin. Which aches, pains and attributes of growing older to attribute to this? Unexplained foot pain is more likely from Lipitor..still checking that. Ive been taking it daily during spring, summer, fall for 3 yrs...it is always allergy season here in swampy Washington DC. If I am late starting in March, it takes a few days to push back the headaches.And then it works wonders. Zyrtec for two days gave me the racing heart, panic etc described in other posts here. M 57 3 years
