 1  seasonal allergies fatigue, vivid dreams, stomach pain, diarrhea I am so glad to be off of this medication. I didn't have the withdrawls that some mentioned, but I couldn't believe how much better I felt after I stopped the meds. I was so refreshed in the morning and didn't feel like a zombie! I was worried I had irritable bowel syndrome or an ulcer, but the stomach pain and diarrhea stopped a week after I stopped taking Zyrtec. I'll stick with Claritan and Sudafed. F 40 6 months

 1  chronic (over 2 years) hives severe leg aches, breast tenderness I was prescribed Zyrtec to help control chronic daily hives. It didn't seem to have any effect at all on the hives and for the entire time I was taking the drug I felt like I had the flu with body aches that were particularly bad in both calves. All bad effects were gone the day after I quit taking it. F 53 21 days

 1  Seasonal allergy Took 1 24-hour tablet. Instantly effective on symptoms, but 4 hours later I became very drowsy, had trouble remembering things, and felt like I was in a mental fog. I will not take it again, and cannot recommend it to anyone. M 60 1 times

 1  allergic rhinitis my son has been taking claritin prn for the past few months for allergic rhinitis sxs. We did notice it made him hyper, especially if we gave it to him in the am. We switched to zyrtec last night and noticed that he was extremely irritable all day today, crying at the drop of a hat. We didn't thnk much about it , as he was also sick. However, tonight after his second dose, he woke up at midnight hysterically screaming. When we went to comfort him , he was aggressive and angry and very difficult to console. Had I not read the other comments on this site, I would not have believed it was the zyrtec. I will never give it to him again! We also noticed more aggressive and moody behavior when he was on singulair. He has been off that for 2 days now. We will go back to claritin and his flonase nasal spray. Please call your pediatricians and allergists if you experience similar reactions in your children. If enough people make complaints , then action will be taken. M 2 2 days

 1  Allergies Extreme sleepiness and depression I took my first and last Zyrtec pill last Friday to help me with unpleasant allergy symptomps. I should have explored this drug better! The first night I slept 11.5 hours and the whole day felt like I was under influence of heavy drugs. Sleepiness, detached feelings, depressed. I slept after lunch and in the late afternoon. Saturday night was not better, again, slept over 11 hours (I usually can't sleep longer than 7-8 hours) and got very depressed and angry. This is today and I hope that Zyrtec will get out of my system quickly. This must be a strong drug and people need to be warned. Especially those sensitive to certain medications, I am sensitive to Benadryl, but thought that Zyrtec does not have sedative effect. I hope I will be back to my old self quickly! F 42 1 days

 4  Year round allergies None I had been taking Zyrtec for many years until it went over the counter. I then switched to Allegra, but it didn't help my symptoms as much as the Zyrtec did so I'll be going back to the Zyrtec. F 49 7 years

 1  hayfever She-devil; off-the-charts mood swings It cleared up my allergies, hands down better than any other I'd ever taken. I took it one day, and was a raving lunatic. I didn't know what my problem was, but I didn't take the pill again the next day and I was fine. A week later, I took another dose. I was ready to kill someone, literally. I will never take another one of these pills. F 52 2 days

 5  Allergies mild fatigue doesn't even compare to the fatigue and nausea that would result if not taking Zyrtec PLEASE DO NOT CONFUSE ZYRTEC-D WITH ZYRTEC. Zyrtec-D contains a decongestant which shouldn't even be available by perscription because it causes hyperactivity, anxiety and sleeplessness in almost everyone who takes it even short term. My daughter has seasonal allergies, and allergies to dust mites, which essentially means she's allergic all year. She has been taking Zyrtec for 7 years with no noticeable side effects. Before taking Zyrtec she would wake up every morning with an upset stomach from the drainage going into her stomach. Zyrtec absolutely stopped this. It may have have a mild effect of drowsiness, but without it she would be facing nausea every morning, sinus infections every spring and bronchitus or pneunomia every fall. She had to get off of Zyrtec for a week to undergo allergy testing and she was so nausiated she couldn't go to school. She developed a sinus infection that required two antibiotics to clear it up. Long term studies show this drug is SAFE. If your side ef F 14 7 years

 1  Eczema, seasonal allergies Extreme mood swings, anger, inability to cope with even the slightest disagreement, screaming, drowsiness. General insanity. DO NOT give this evil stuff to your child. My daughter experiences both a chronic eczema as well as hive like breakouts made worse during allergy season. I have tried Zyrtec on 2 occasions and experienced the same side effects both times. I can't even believe I tried it a 2nd time. I am even more galled that it is now available OTC. Have you noticed that when looking through the list of antihistamines here that Zyrtec has the most responses??? This is why. I believe it's just too strong for kids. Stick with good old Benadryl at night. F 4 3 months

 1  Seasonal allergies My 4 yr old daughter has experienced many of the same side effects as everyone else. She was on Zyrtec about 2 years ago for about a year and started having terrible temper tantrums and they escalated over time. You could not reason with her at all and it was like she didn't even hear you (exorcist-like). The smallest thing would set her off. We stopped giving it to her because we didn't really see any benefit. Her mood changed dramatically but we just attributed it to getting out of the terrible twos and threes. We just started giving it to her again about a month ago and the violent behavior came back about a week ago. We never made the connection to Zyrtec until now. The light bulb went off on Tuesday that it might be the problem because her diet hadn't changed and nothing else had really changed. I found this website and was blown away at the postings. I looked at the side effects listed on the pamphlet from the pharmacy and the only thing it says related to behavior is possible change in mental status. I can't believe this medicine is now sold over the co F 39 30 days

 1  Allergic outburst to pennicillin My allergic hives seemed to worsen after I took zyrtec, my mouth and lips were dry ans sore and my feet and hands had swollen to the point where I didn't fit my shoes. So the doctor switched me to something else which represses my immune system so it will stop fighting the pennicillin which has already left my body days ago?? I also suddenly craved snacks and food, I ate two tubs of Ben&Jerry's in three days, I usually never eat that. The night after I stopped taking Zyrtec the hives I alreay had from the allergic reaction had become far itchier than they had ever been and I couldn't sleep all night. I took another pill just before stubmbling upon this site because I thought it might help the itch. I'm regretting that, but the itch is still not gone hours after taking the Zyrtec eventhough I hear others speak of immediate itch-relief. After reading all of these comments I am quitting zyrtec immediately, I will take benedryl against the itch and just tough this thing out. Hopefully, since I have only taken zyrtec for a few days I will not experience the weeks of itching others talk about. in teh past I have taken zyrtec twice over a few weeks with no problems, although the allergy, just as it does now, took a ridiculously long time to disappear. I have hives from my neck to my feet, but reading your alarming itch-accounts and seeing how my itch already dramatically worsened after just 4 10mg pills I am far too afraid to continue this drug. So glad I found this site so soon. F 25 4 days

 3  adult onset spring allergies lethargy, weight gain, rash on my neck, low libido It has worked better than Claritin for my adult onset spring allergies; I originally tried "natural" remedies, which did nothing to help the sneezing, dripping and achy eyes. However since starting Zyrtec about 2 months ago, I have been needing 9-10 hours of sleep, and still have a hard time getting out of bed. And I have been gaining weight for no apparent reason, about 5 pounds in the last 2 months since I began Zyrtec this year. And a reduction in sex drive the last couple of months. And a mild itchy rash on my neck the last few weeks. As my allergies are seasonal, and they usually subside around now, I stopped Zyrtec 3 days ago and have been having trouble sleeping. Last night I lay awake most of the night. I am very happy to have found this web site and now know that these changes are because of Zyrtec. However, I would take it again next year, maybe try taking less, and taking it at night, or maybe try Claritin again because the constant sneezing and dripping and sore F 58 60 days

 4  seasonal, envt., & indoor allergies Never thought I had any until now; all of these horrible reviews are crazy to read. I wonder how many of you were/are suspect of medication to begin with, as many of these symptoms sound psychosomatic. And kids? Kids are, by virtue of being learning machines, always changing, and are thus frequently unruly, unpredictable, or difficult. That said, they are also extra-sensitive to the mental (side-) effects of any drug (or food, for that matter. Hippocrates himself said, "Let your medicine be your food, and your food your medicine.") for related reasons - developing brains, fast metabolisms, and little organs. So... think hard before feeding your kids pills, and don't expect a magically perfect cure devoid of any side-effects; modern Western medicine is still all about treating symptoms, be they proximal or fundamental. (Until there are several more generations of advances in genetics, treating causes is nigh impossible.) Like everything else in life, it's a careful cost/benefi My father's a well-respected M.D. who has always relied on Zyrtec when the traditionally weaker antihistamines (Benadryl, Claritin, Allegra) aren't strong enough but courses of antihistemic shots are too difficult or involved. And his endorsement is NOT motivated by arrangements with any HMO or drug company, as he continued to proscribe/recommend it to me and other family and close friends, at full out-of-pocket cost, after it was dropped by my health insurer (yet months before it was available OTC).

 3  allergies when I was taking it: drowsiness, eventually lost effectiveness. when I stopped taking it: trouble sleeping, bad dreams, depression, trouble concentrating, a few days of bad allergy symptoms (which cleared up) I took Zyrtec daily for about 5 years. Worked really well at first. Had a little drowsiness when I first started taking it, but that subsided once I got used to it. I decided to go off it a few months ago because it didn't seem to be working as well as it used to, and because I suspected that I was dependent on it for sleeping. The trouble started when I stopped taking it. I had trouble sleeping for about two weeks, felt really depressed, had terrible dreams, and scary thoughts. Also, for the first few days after stopping, my allergies were really awful--itching, sinus pressure, headache--but then they actually started getting better. Now I just use Simply Saline, and occasionally Benedryl. F 23 5 years

 3  Allergies I have taken Zyrtec probably since about 1996. I noticed whenever I tried to stop taking it I would get itchy. If I take it then it stops. I always thought that was why I was taking it to stop the itching. Now after reading other people's ratings, I am finding out that trying to stop it is what is causing the itching. I always take it at night, because at first it did make my sleepy. If I don't take one at night by morning I am starting to itch, palms of hands and feet, head, arms. I am going to see if I can get off of it and the itching goes away. Claritin just doesn't stop the itching. I am shocked that what I might actually be experiencing is withdrawal from this medicine. Another way the pharmaceuticals get you hooked. I didn't notice a weight gain that I would blame on that, but maybe if I start losing then I'll know. F 50 12 years

 1  sinus, coughing, congestion My 5 year old son has been on both Zyrtec and Singulair for about 2 years now and has MAJOR behavior issues. They have become worse as he's gotten older and we've been baffled as to what could be the cause. We recently saw a psycologist who almost diagnosed him with ODD. Our house has become a battle zone and every day we walk on eggshells hoping nothing sets him off. I'm astounded that so many other families are experiencing the same problems! I wouldn't have thought these medications would have been the cause of such anger. I am taking him off of both medications and am hoping for the best. It's unfortunate that we've lost out on so much because we were mis-informed. It's really up to us as parents to read read read and always question our health-care professionals. F 32
