 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

 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

 1  Post Nasal Drip-itchy eyes Dry mouth, couldn't quench my thirst. Metallic taste in my mouth, sleeplessness, dry cough, crying for no reason.I started an excercise class at a womens gymn and when taking my pulse in my neck I found I had an erratic heartbeat and had never experienced this before. I decided to research the internet on Claritin and found that many others were having similar problems. It should be taken off the market!!!!! I will go back to Benedryl when needed. F 78 2 days

 1  post-nasal drip Insomnia, difficulty breathing, palpitations, chest tightness, extreme fatigue, dazed feeling, joint pain, anger and irritability. It did not cure my postnasal condition, although it has helped with allergies to various pollens. The similarity of my symptoms to those of other users is most comforting - I had been afraid of other possible conditions related to age. I have discontinued this drug and do not think that it should be taken regularly. M 75 10 years

 3  allergies Worked great for my allergies. However, it made me extremely sleepy. Glad I took it over a weekend, I could not stay awake. quit taking it after 2 days, and eventually the sleepyness subsided. Great for allergies, But I wouldnt take it again, due to the sleepyness it caused M 68 2 days

 1  For allergy If you have ever had joint pain issues, this stiff will exacerbate it to the point where you may scream with pain as I did with one pill. My left knee blew up to the size of a grapefruit, unable to leave my bed. This is a horrible drug and this side effect should be listed on the box. Never again. Where is the FDA when we need them?

 2  Seasonal allergies Have taken the drug occasionally (once every couple of weeks or so) for a year. After a doctor recommended it for problems that I did not realize were allergy-related, I started taking it more frequently (2-3 times a week). I started having episodes where I would have an extreme feeling of horror or depression wash over me, usually just for a matter of seconds, but it was very frightening. This seemed to happen just about the same time every time I used Claritin. I know this drug works very well for a lot of people, but I think these types of symptoms should be mentioned more prominently because if someone does not know that Claritin could cause them, their medical treatment could get very complicated.

 1  Seasonal allergies Stomach pain, gas, belching, insomnia, nightmares Have taken other antihistamines for years without incident. I am now on my fourth day after taking one dose. Gastric distress subsiding but still present. Insomnia is bad. Felt exhausted last night but was unable to fall asleep for 4.5 hours. Racing thoughts and nightmares, very unusual for me. Took klonopin .25 mg and got rest, although I am not sure that I slept at all. M 66 1 days

 1   I have always had a lower than normal blood pressure but after taking Claritin, it dropped to 96/58. I have been lightheaded and saw the doctor who diagnosed Positional Vertigo and gave me exercises to help. I stopped the claritin, did the exercises and it gradually went away. My nose was so sore, i took one claritin last Thurs thinking the diagnosis was probably not related to the med. This is Monday and I am so confused, light headed, room spinning, and feeling panicky. However, I can tell that today is better than yesterday, so as the Claritin clears my system, I hope to return to normal.Powerful drug if one dosage can lower blood pressure to a dangerous level, cause mood swings and blurry vision. I am surprised the number of people who were able to connect the drug with the symptons when it makes you unable to read a book or remember how to turn on the diswasher. Dangerous drug F 66

 1  Allergic asthma Horrible shifts from feeling extremely cold to having hot flashes. Developed bladder issues... went in for a UA and test was negative for infection. Keep having bladder pressure, uncomfortable feeling of having to urinate often and bladder burning. Also feel very tired and down in the dumps!! Stopped taking Claritin as of yesterday and hope these issues resolve! It worked for my allergies and kept my allergic asthma at bay... but not worth feeling like you have a bladder infection all the time!! F 66 2 weeks
