 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!

 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

 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

 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

 5  Seasonal Allergies None Great Drug for me and my family. Helps wonderfully with our allergy symptoms. F 30 5 years

 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

 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

 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

 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

 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

 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

 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

 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

 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

 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

 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

 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

 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
