 1  Seasonal allergies I began taking Zyrtec because the Claritin was not working for me. I noticed the allergy symptoms clearing very quickly. HOWEVER, by the 4th day a dark sad mood came over me - for no apparent reason. (I am a 44 year old woman that understands her body well - when I am hormonal, etc. This was not hormones.) By the 5th day, I was feeling suicidal and extremely concerned by the depression closing in on me. I was also very very tired, even though I had slept 8 hours the night before. Then, I remembered that we had taken my 9 year old son off of Zyrtec because we thought it was affecting his moods. Apparently, we were right... his out look on life and his general mood changed drastically a couple of days after taking him off Zyrtec. For some reason, I thought I would be immune to the side effects. But, I was not. I would recommend NOT taking Zyrtec. F 44 5 days

 1  Allergies Started taking zytrec about 2 years ago as Allegra and Clariton werent working anymore. Doc suggested the change. Just this Dec. 2010 I started getting hives on my hands - went to the doctor who was "bewildered" since it was only there and my eyes kept swelling up, he said I must have alot of allergies and told me to keep taking zytrec and put me on preidsone for four days. The hives cleared up for the most part and I started wondering about the long term use of zytrec and looked it up on the internet - I decided to stop it cold turkey and recalled how I thought my allergies were getting worse in the fall of 2010 as if I went off the zytrec for a few days I would start feeling awful and once I started it again I felt better. However the hives on my hands started up while I was still taking zytrec. So I went cold turkey off it, I am currently on day 21 off this nasty drug. Its been tough, but Ive been drinking ginger tea and using apple cider vinegar on the hand hives and am s F 49 2 years

 1  Allergies Heed my words: STAY AWAY FROM ZYRTEC! I discovered Zyrtec in May, 2010. Totally cleared up my allergies and I was sold. I used it off and on, whenever I had bad days. I started using it more consistently every other day in mid December. I also started to get dizzy when I tried to sleep on my sides - or try to sleep in general. What made this worse is it was making me extremely tired. Thought it might be BPPV or something more catastrophic. Went to the dr. and he prescribed me Trazodone - said the feelings must be sleep related. Didn't take them as I could tell he didn't quite know what it was and Trazodone's top side effect was dizziness. Stopped a week ago after exhausting searches on the internet about anything related to dizziness. Zyrtec and this site finally popped up. I also learned through further reading it is an ototoxic medicine (great to know now since I'm a MUSICIAN/COMPOSER), quit and after about 4 days started to feel like myself again. It's been a week and I'm almost fully recovered but have some new humming in my ears. Everything else is normal again fortunately. Thanks for the new tinnitus, terrible brain fog, depression, misery, and terrible dizziness Zyrtec! Time to flush this deceiving drug down the crapper. M 33 5 months

 3  Cholinergic Urticaria I felt cetirizine sufficiently suppressed my CU, whilst I was taking it. I only experienced an attack on the first day, after that none. Sadly, I had to stop taking it despite its efficacy as it was causing me to have severe chronic headaches, sinus pain,made me feel out of it, sleepy, made me need at least 10 hrs of sleep, and impaired my coordination and focus. It isn't a horrible drug as it has it's positives but I believe the negatives outweigh them for me. M 17 3 weeks

 5  Hives Fatigue Yes, Zyrtec makes me tired, but it is certainly better than being covered in hives! It has been extremely efficient at curing my itchy skin (but less effective for nasal allergies), and I am very happy with this drug. F 43 365 days

 1  Seasonal Allergies Severe depression and anger. Every year we would warn my son's teachers about his behavior believing he was reacting to the discomfort from his allergies, never realizing it was the Zyrtec. Pediatricians should include behavioral changes in the list of side effects and symptoms. M 14 4 years

 1  Allergies Gave to my 3-year-old son for constant cough from allergies. Worked on cough, but turned him into a monster! He would cry and throw huge temper tantrums over the slightest upset. He has been angry and aggressive- attacking his 4-year-old sister when he gets mad. He is normally a sweet child with normal behavior. I could not even recognize the monster child he had become!! He also has had nightmares that have caused him to cry out during sleep. It took a few weeks to realize the medication is what caused this change. We had given it to him intermittently, so it was not as obvious. His sitter and I were tallking about his behavior and when it started- and together had the "aha!" moment. He will not be taking this anymore! F 43 3 weeks

 2  asthma/allergies my son was on Zyrtec at the age of 7 for about two weeks. It did not help his allergies. One day he woke up screaming with abdominal pain and a belly that looked like a 5 month pregnant woman. We rushed him to the hospital and discovered that he was completely blocked in his bowels. The dr said that this was caused by the Zyrtec. We took him off of it and within days he was better. M 7 14 days

 5  Seasonal allergies none It works, quickly and effectively, where all other non-drowsy antihistamines have failed. I take the generic Walgreens/CVS/Wal-mart version as needed (about once or twice week during the winter) and stop sniffling/sneezing within fifteen minutes! As a side note, I try not to take any medication regularly unless it's absolutely necessary, to protect against potential dependency or cumulative side effects. This may influence why I have nothing negative to report. F 26 1 years

 4  Allergies Tiredness, sometimes dries me up too much. This works very well, but sometimes over dries my nose, so I stop it for a day or two. Makes me rather sleepy, so I take it at bedtime and sleep like a baby. M 53 1 months

 1  Allergies Horrible nightmares, tightness and swelling of tongue and throat, scratchy throat, hoarseness, tiredness. I decided to try Zyrtec because Claritin doesn't do anything for me, and Benadryl gives me panic attacks. The first day was okay, but I did not notice any side effects. The second day, I had a strange dream where my father came on to me sexually. I have never been abused or molested ever in my life, so there was no reason to have such a nightmare. Then last night, I had a dream where my body was covered in an awful rash, my throat swelled up and I could hardly breathe, and I was losing vision and consciousness and I couldn't see anything but knew I needed to put on my clothes and go to the ER. I was also screaming my husband's name in the dream, but he couldn't hear me because the bathroom fan was on. I woke up in tears, relieved it was a nightmare, but still very disturbed. I haven't taken the Zyrtec in 2 days... hopefully it is out of my system now and the nightmares will stop. My throat and tongue still feel swollen. My stepdaughter is 6 and so far has no problems with the zyrtec - she takes a 5 mg dose every day. F 30 3 days

 1  Seasonal allergies Itchy hands and feet with occasional burning on the soles of my feet after 3 days without a dose I have wanted to stop taking Zyrtec for the past year but the closest I've gotten is taking it once every 3 days which is when the itching sets in. I started my research today on the itching and realized, like so many others, that it isn't just me. My doctor told me the itching must be from an allergy to something in my house. Not so - it is definitely withdrawal from the Zyrtec. I am going to cut back to half a pill every three days and buy Claritin to help minimize the itching. After a week or two of half pill doses, I will try to stop completely. I'm determined to do this quickly. The sooner, the better. To everyone else having similar issues, I wish you the best of luck. This issue should be publicized and the exact effect this drug is having on our bodies needs to be discovered. F 40 2 years

 1  allergies Exhaustion, weakness, sleep problems, dry mouth, weight gain I had been successfully treating my allergies with Allegra for several years, until my insurance company switched me to Zyrtec about a month ago. Almost immediately I started feeling tired and miserable all the time, and noticed my weight creeping up. I began to suspect the change of medication and after about three weeks decided to quit taking the pills to see if they were causing the trouble. Sure enough within a day or two I was feeling back to normal. I did have some itching, mostly at night, but nothing as severe as described by others, maybe because I hadn't been taking it for very long. After five days off, I tried to complete the test by taking one pill last night at bedtime and already today I have been so exhausted I could barely keep my eyes open all day. Thank goodness I didn't have any real work to do. I've had enough and will learn to live with the sneezing if this is my only alternative. F 60 30 days

 1  Hay Fever, Itchy nose, Itchy throat Where to begin! I feel as though I am late with my response to how this medicine really took away 1 year of my life in a sense. I just found this site but I went through Hell getting off this drug back in 2009...before beginning this drug I used to be a very deadline driven ambitious person, confident in myself and easy going. This drug completely changed me. I didnt notice that I had "changed" until those around me started saying I had gained alot of weight (30 extra pounds--the heaviest I have ever been was 125 and I was almost 160 lbs on this med.) I started getting in to major arguments with my boyfriend to the point where I felt psychotic! Over the littlelest things, crying spells, sitting in a room thinking about life is not worth living, thinking of the worst in everything---that there was no bright side. I felt so depressed. All my problems in my life where intensified with this drug. These side effects began about 6 months of starting the drug. Thats when the major a continued...I was late on my assignments and at work I was also falling behind to the point I was gonna get written up! totally not my personality. The sad thing I didnt even care. I just wanted to go home and sleep all day. I never went anywhere...I was a zombie. I found your website and immediately stopped taking this drug. I used Aveeno to bathe and lotion myself down with to stop the itching. I could shave my armpits for a while though because i broke out in a rash a month after stopping the med. I was able to shave after a few months after that. I drank tea for my throat and just endured the seasonal allergies. Every time I itched I just put lotion on. I very well weaned off this horrible drug a year later. I have lost so much weight --especiallyy around my stomach area! I am now 140 something getting close to 130 lbs and hopefully back to my original weight in a few more months. I am trying to go back to school and I am doing way better at work--I can concentrate now. I dont sit at home sleeping my life away. I get out and socialize now and am more active. This drug made me anti-social. I just wanted to say that you can wean off this. I dont take anything for my allergies anymore. I just dont trust the side effects and its not worth my life. Please spread the word.Would not recommend to anyone, please stop taking this drug if you have been experiencing these side effects. F 28 16 months

 3  hives Hair loss, fatigue, weight gain, irritability. Wow! I have been wondering for a while why I am losing my hair and cannot lose weight that I have gained. I have never had this much of a problem losing weight. I was actually pleased when I read these comments to finally figure out why these things were happening to me. The only problem is it is the only thing that stops me from itching. I don't know what I am going to do because either way, with or without it I will be miserable! Does anyone have any suggestions?

 1  seasonal allergies After trying to wean myself off of the generic Zyrtec once allergy season had passed, I had trouble sleeping. I would wheeze and/or cough. If I fell asleep, I would wake up 2-3 hours later and go take an allergy tablet, which would alleviate my breathing within an hour. This isn't how previous over-the-counter allergy medicines worked for me, so I called the manufacturer and reported that I believe I have an addiction. I would not recommend it after researching the public's reaction to taking this drug. I feel like I have to go to an allergist now to get off this drug and manage my allergies otherwise. In the past, I only needed allergy medication in the spring, late summer, and fall. F 44 5 months
