 3  allergies Lethargy and lack of motivation at first, with occasional night sweats and strange dreams. Heart palpatations - check. Heart burn - check. Later, extreme vertigo and nausea. I occasionally suffer from seasonal allergies with itchy eyes, runny nose that eventually gets stuffed up and leads to chronic sinus infections, which is why I was looking for an allergy med in the first place. I've been using the regular 24hr. Claritin on and off for months, and if the side effects had just been some fatigue and night sweats, I probably could have tolerated it for longer as it did relieve my allergy symptoms. Last night, however, and this morning I was experiencing severe vertigo (room spinning) with nausea. I got so scared, I started to cry. I couldn't drive, I could barely get up and down the stairs without fear of falling. It's been almost 24 hours since taking it, and fortunately the symptoms have subsided. That's it for me and Claritin! F 32 7 days

 1  allergies My 9 year old daughter took OTC CVS Loratadine for 4 days and then experienced severe anxiety, depression, sleeplessness, bladder discomfort, back pain, loss of appetite. These reactions were dramatic and never before experienced by her. It took detective work to discover the connection with the medication. We are hopeful she will improve over time. This has been a hideous, needless experience. Why after years of knowing of these severe side affects does the packaging not reflect the accurate side affects. The CVS packaging had no warning whatsoever. This truly seems criminal. I can see no reason to have a child needlessly exposed to these side affects when other medications with less affect may be used. I further believe that the product should no longer be offered OTC or should be pulled all together. F 9 5 days

 3  In-door allergies stomach pain, muscle pain, headache, sleeplessness My doctor prescribed the generic Ranitidine (Zantac), the generic Loratadine (Claritin) and Singulair for acute hive-like allergic reactions to in-door allergens. Am I the only one who reacts strongly to thrift and second-hand clothes from stores—not from individuals??? Anyhow, after a week of the combo, I decided to try each separately to assess where the different side-effects were coming from. I experienced headache, stomach pain, muscle pain and sleeplessness with Loratadine. Extreme pain in shoulders and neck finally made me stop. It was worse than the pain it was supposed to treat.

 2  allergies Uncharacteristic feelings of being irritable, no patience, feeling aggressive, anger, ringing in ears, nightmares, cough, unable to catch my breath. Took it years ago for seasonal allergies, tried it when they flared up this year. Didn't help the allergies very much and do not like the way it makes me feel. F 43

 3  watery eyes and congestion My six year old son was taking this and it worked great for his allergies but this is one scary drug he was having horrible dreams and hallucinating he was scarying me so bad and than two and two came together and it was claritin. This really needs to be a warning because it is so scary. It really does work great for the allergy side M 6 8 days

 5  nasal allergies/fluid in ear none It seems impossible, but I credit claritin for "curing" my life long battle with nasal allergies. My doctor prescribed it several years ago, and I took it daily for approximately 2 years. I ran out one day, and never got around to refilling the prescription, but neither have I ever had problems with nasal allergies again! I'm having fluid in my ears, so I'm trying it again. Let you know how it comes out this time. Sorry so many others have had side effects. F 48 2 years

 1  Hayfever Heart palpitations constantly, anxiety and rash. Already prone to heart palpitations so tried to ignore them but got so bad that I knew something else was wrong and discovered it was because I had just started taking Claritin, since coming off two days ago palpitations have stopped and rash going F 27 5 days

 2  ear infection dry mouth, nervousness, headaches, elevated blood pressure and pulse rate My doctor ordered me to take Claritin for 2 weeks for the ear infection. Prior to this my blood pressure never went up above 110/77. While taking Claritin, it went up to 135/89, and ever since (it has been 3 weeks since I stopped) my bp has been above 140/89. Last reading was 145/92. Any one else experienced this? Maybe I am susceptible but if I am, Claritin kicked me over to the dark side. Never going to take it again -- of course now I can't with my bp up. F 55 14 days

 1  For hayfever relief I am usually a stable level-headed individual but Claritin changed all that, causing severe depression, exhaustion and paranoia by day three, which made me miss work for a couple of days whilst I came off of them, the process of which gave me a terrific headache, but I was completely back to normal once I stopped taking them. There should be some warning about depression in the packet, not just about 'anxiety.' That's an understatement. 5 days

 1  seasonal allergies Mental fogginess, bloated abdomen, heartburn, "air hunger" (couldn't "catch my breath"),and crankiness Took the generic form. My sneezing attacks stopped, my sinuses cleared and all was well for about one month. During the second month, the symptoms of fogginess and irritability began. Then came the abdominal symptoms which made it uncomfortable to eat or even drink my beloved water! The air hunger was the last straw! Two to three days after stopping it, all symptoms resolving. F 53 2 months

 1  allergies Stupor, fatigue, somnolence(extreme drowsiness), loss of concentration, loss of motivation, black outs with sleep. I only took it for two days and I felt like I was on a strong "downer" like Klonopin. I am a very high-energy, productive person and Claritin made me pass out if I sat still for more than a few minutes at a time. When I fell asleep on several occassions, I would wake up and not know where I was or what day it was. F 25 2 days

 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

 1  hayfever My 5 yr old son took it from 5/6/08 to 5/17/08. About 8 days after taking it, started to show signs of stuttering or stammering when talking...it got very severe very quickly to the point that he could not even say a sentence at all. It was not the same as a normal stutter that a child may have, he even started to take deep breaths before and during speaking. One side effect of claritin in children is dysphonia which is a disorder that effect your vocal cords and has similar symptoms as a stutter. Only 2 percent of patients had this in a study that was conducted in children. The day after we took him off claritin, the stuttering or stammering improved very much. Now it has been 12 days since taking it and he is almost talking normal again. Took him to his pediatrician when it was still quite bad and they did not feel it was anything to worry about because they felt it was normal stuttering. However, they did not get to hear how he sounded because he did not want to talk to the dr. Als I realize there are many who have no side effects from this but I think it is pretty important for people to know this can happen. I had not idea that something like this could be a side effect from any drug let alone an over the counter drug for children. It just amazes me that this happened. It is also scary to me because I am sure there are others out there that have this side effect and it goes undetected because who would think it could be linked to something like claritin. I only checked into it because my husband said check the internet for side effects...in a almost jokingly way. Well no joke, it happened to us. I now will not try anything else for my sons hayfever, he is going to have to suffer because I am not willing to take any more chances like this. It was very alarming and scary and we were not sure that he would even get back to talking normal again.I would not recommend this to anyone ever. F 12 days

 4  Allergies Almost no sex drive whatsoever. I usually, like most guys have it on the mind most of the time, but not while taking Claritan. Did alleviate my allergie symtoms very well. M 45 2 months

 3  Allergies, runny nose My son's pediatrician recommended Children's Claritin for his non-stop runny nose. The first few days I didn't notice a difference. Then, for several weeks the running seemed to stop until the late afternoon (he would take the pill in the morning). After about five weeks, it seems as though his nose is running all day again. We will probably stop using it. We didn't notice any side effects with our son. I read some people commenting on children's aggressive behavior and hallucinations with this medicine but we didn't experience any change in our son's behavior. M 4 5 weeks

 3  Seasonal allergies Depression, loss of appetite, feelings of absolute worthlessness (almost suicidal), lethargy, general malaise, extreme tiredness. I loved how Claritin worked on my allergy symptoms, but I've been so tired and irritable the last few days. I was about to go to the doctor to see if I have mono or something and considered the possibility of pregnancy (no) etc. I finally decided to take a break from the Claritin and look up side effects etc and am very glad to see that I'm not the only one with negative side effects to this drug. I won't be taking it again, although I know many people that take it with no problems at all. F 40 6 days
