 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

 3  Rash/multiple food allergies/sinus Short-term memory loss, inability to concentrate, disorientation, groggyness, feeling sleepy, tired and somewhat paranoid. Inability to perform complex tasks. I was taking the drug on and off, maybe that is the reason for the effects. After several days of stopping it, I feel like a normal person. Even though the allergies are more intense. The drug does help the allergies. M

 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

 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

 1  seasonal allergies Extreme anxiety, vomiting, shaking, couln't sleep...I felt awful! I've suffered from depression in the past and it felt like everything was coming back. After 24+ hours the dire effects wore off so I know that's what it was. Horrible, out the window it goes! I also took it with Flonase which is a nasal steroid so it seemed to be a combination of effects. F 3 days

 1  Allergies Insomnia, irritability, loss of concentration and rapid heartbeat. Getting rid of my allergy symptoms created a list of side effects that were much worse than the original problem. Loss of sleep occured after 10 days of taking the drug and was followed by irritability and anxiety. DO NOT TAKE THIS DRUG. There must be other allergy medications that do not drive one to the brink of maddness. F 25 days

 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

 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  seansonal allergies My 8 year old son was perscribed claritin because of seasonal allergies. He was a very outgoing kid and was very easy going. After about a week of taking claritin his mood changed and he became very irratable and his would have very bad mood swings. I thought that it was just a faze that he was going through and continued to give it to him. I had a conference with his teacher and found out that he was not paying attention in class and when she would address him about it he would say that he couldn't help it, it just happens. The teacher was concerned and wanted to test him for ADD. He was a straight A student last year so I was lost and didn't understand why the sudden change. I decided to do some ressearch and I'm so glad that I found this web site. I will be sharing this info with everyone that I know. Especially with his teacher. My son will never take claritin again. F 25 days

 1  Allergies All of a sudden my body started aching from head to toe! I could Really feel it in my Legs, Arms, Hands, and Shoulders. I also had Very Vivid Dreams and would wake up Extremely tired and just couldn't get it together. I had absolutely no idea what it was until I started reading these reviews. The worst part is it didn't relieve my allergy symptoms. My doctor suggested I try a children formula of another brand. The aches and pains were the Worst with Claritin! F

Patient History
 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  allergies diarrhea I gave the liquid claritin to my 2 year old daughter for her runny nose. It did not completely stop the runny nose, but her nose did run less. she went from having thick yellow mucus to thin clear mucus. It worked better than the Zyrtec she was taking, but the diarrhea she had was unbearable. I stopped giving it to her and I am going to consult the pediatrician about alternatives. F 2 1 weeks

 2  Runny nose I gave this medicene to my daughter to help her constant runny nose. Within no time, I received a call from the day care center about her behavior. She was jumping on other kids as they tried to nap. She refused to nap and wouldn't listen. After putting two and two together, I realized that she had been irritable around bed time and in some cases just refused to go to sleep. Truly not worth the change in behavior for a toddler F 2 10 days
