 1  Allergies Irrational moods... quick to anger, rage, flat affect, living in a fog, not myself, loss of sex drive, lethargic, sad, weight gain, itchy scalp and face and eyes, general crummy feeling. It never occurred to me that Zyrtec could be a possible reason for these side effects. I literally had to start analyzing everything I was doing or taking to see if I could figure it out. The weight gain and mood and all symptoms coincide with length of time I've been taking it. I take the 24 OTC Zyrtec and try to wait a day between because I'm generally not the person to take any drugs at all... even things like ibuprofen. Birth control pills are the only other thing I take and have been on them for 3 years with no bad sad effects. I really hope that stopping the Zyrtec will make me feel like myself again. F 28 6 weeks

 1  allergic rhinitis none, and none with my son Didn't seem to do anything at all for either me or my son. Flonase works much better for me.......100% better. For my son, he has to use albuterol, patanol (for his eyes) and flonase plus zyrtec when the allergies kick up during Tball season.....otherwise he is a coughing, pussy eyed, boggy sinused poor little pool of a mess. I don't think the zyrtec does anything for either of us! F 28 4 years

 1  Allergies and Asthma Didn't notice any side effects when I was on it except a constant stuffy nose, worse asthma but I am unsure that is because of the ZYRTEC. I am experiencing bad withdrawals right now. This is my second time trying to come off of it, using Clariton as a supplement to try to get off of it. This is my third day and I am very, very dizzy and extremely nauseous. I am praying that I do not vomit. I do not want to take it any longer so I hope it goes away. The first time I tried to get off of it I was so itchy I could not work or sleep. The clariton has helped with that, but I want to get off of that also. I have successfully withdrawaled off of effexor, advair and singular and it took me 1 year. I never thought Zyrtec would have such bad withdrawals since it was an OTC allergy medicine... Lets face facts: All medicines are horrible, DON'T use it! F 28 1 years

 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

 1  allergies stomach pain, weight gain, headaches, deterioration of vision, mood swings, digestion problems, rash, body aches, brain fog, memory loss I took zyrtec for about 2 years almost every day. I recently stopped taking it due to the realization that I didn't need allergy medicine year round and its a financial burden. I have never experienced withdrawal symptoms from a drug in my life, but on day 3 of no zyrtec I experienced hell. I had unbearable itching all over my body, from my fingertips to my scalp, to my eyelids, and the inside of my toes. You name it, it itched. The itching was so bad I made myself bleed from scratching. Then the nausea hit. I could only keep down a few bites of food and that's it. I started having blurred vision which led to vertigo. I am currently on day 5 of no zyrtec and the itching is still severe. The only thing I want to do is get zyrtec off the market. I went to the doctor to see if there was anything to do for the discomfort, and he told me to begin taking zyrtec again. No one believes that an allergy med can have withdrawal symptoms, but thank God for forums like this. I don't feel like I'm crazy anymore. This product needs to be taken off the market! F 28 2 years

 1  seasonal allergies My 6 year old daughter had suffered severe side effects recently from singulair, so after those symptoms subsided we tried Zyrtec which created the same side effects which includes extreme confusion and anxiety, suicidal thoughts, bizarre sensations and hallucinations. Keep in mind that before these medications my daugher was care free. Unfortunately, the anxiety has not completely subsided. My daughter is not sure what is real and what is not anymore, and the worst part is after many tests and exams her pediatrician will not admit that the reactions were from these medications.

 1  Allergy to cats I was taking 10 mg a day as a test for two weeks to see if I could live with my girlfriends cat Sam when I realized I was fatigued every day I was on it. I woke each day feeling like I didn't sleep even though I didn't actually wake up during the night. I couldn't concentrate on anything at work and didn't have motivation or the energy to workout or do just about anything. I couldn't remember anything either, my memory seemed to be affected... probably from feeling so damn tired all day. Anyway needless to say instead of taking Zyrtec, I sold her cat on ebay. Just kidding. We gave the cat away and are getting a dog. Thank god. Now maybe I'll marry her.... yeah right! If you're allergic to cats ... just get rid of the cat. duh! M 28 2 weeks

 1  Allergies and Ecema My 9 month was taking Zyrtec two days. She has always been so sweet and friendly. Later the first noght she was screaming as if she was being tourtured , falling out , hitting and rying all day long. She has blister in personal areas and scratches like crazy. She is also very argrey , easy to cry and very moody. I can tell her NO and she cries for like ten minutes before she would just keep going letting nothing stop her. I would not recomind Zyretc to anyone with small childen. Doctors push this drug on people not mentioning the side effects and then tha put this crap on the shelves. I would never have given my child this medicine had I know it was cause side effects no matter how small!!! F 28 2 days

 1  Allergies I've rated Zyrtec previously mentioning vivid very strange dreams and nightmares. After having taken it on a few more occasions I've noticed that I feel terrible after taking it. (Note that I've only taken half-pills because the full pill makes me too sleepy.) After taking it always I feel like I am not being myself, have delusions, feel angry and "high" and like a zombie at the same time. In addition, I feel very sleepy, unable to concentrate and to make decisions, and also experience strong free-floating anxiety. This leads me to conclude that this drug influences the brain in some way. It would be reasonable to have this drug off the market to fully test it's side effects. It seems other site visitors have similar experience with this drug, and it needs to be further investigated. If you are considering taking this drug, stay away! M 28 1 days

 1  Allergies Depression, anxiety, vertigo, blurry eyesight, irritability, weakness, lethargy, sleepiness, fluid retention, reduced urination, respiratory depression, drowsiness Taken it before occasionally for seasonal allergies, noticed the drowsiness, grogginess, and fluid retention. Took it two days in a row for the first time and 18 hours later I'm still groggy, miserable, anxious, irritable, dizzy, and pretty out of it. I rarely cry but I feel right now like if I encountered any setbacks I'd break down. I feel physically and emotionally weak and have no willpower to get things done or concentrate at work. It makes breathing feel like a conscious effort, exacerbated by the anxiety. I can't imagine taking this for any length of time and I'm never touching it again. I can't wait for it to clear out of my system. M 28 2 days

 5  itchy skin and allergies No side effects. This drug is a wonder for me. I love this drug. Nothing else worked for me. My itchy skin depends on it. I have to take it everyday or I am miserable. I have no side effects and am thankful since I see so many negative responses. I'm not anti-social, not depressed, not irritable, no panic attacks, no bad dreams,etc. Looks like I"ll be taking this drug for as long as it helps me. 10 years and couting. I'm very glad it's OTC now. F 29 10 days

 5   late onset lethargy & extreme weight gain I've noticed if I take the pill in the morning, that by 8:00PM I'm ready to almost black out, I'm extremely tired! Couldn't figure out what has been causing my rapid weight gain & hunger. I'm ALWAYS hungry, and never satisfied. (I'm not pregnant either!)I've noticed more drastic weight gain in the last few months & I've been taking zyrtec more consistently because of the season. Those are my only complaints, but it does REALLY help with my allergy symptoms. Guess it's a give & take. No more allergies but now I'm fat. F 29 1 years
