 1  Seasonal Allergies Withdrawl, Abdominal Cramping, Foggy, *INTENSE* scary dreams Always suffered from IBS but had been without a flare for almost a year then suddenly was hit with extreme cramping etc. Traced it back to this med so I stopped taking it. If I go without it I get itchy (ears, face, scalp, hands etc)and get a MASSIVE headache complete with nausea. At first I thought it was just a normal migraine but it didn't follow the right pattern and lasted for days. Horrible medication and there needs to at least be warnings of these side effects on the package. F 25 3 weeks

 1  All year allergy and astma Non expect a bit drowsy After taking zyrtec over 15 years (first 5 years seasonal afterwards all year long) it doesn't seem to help anymore. It used to work really good. But now still sniffing and sneezing all day long. But if I don't take it, (I tried to quit zyrtec) I'll be itchy all over and can't sleep. Can't go walking with the dogs 'cause my legs start to itch unbearably. However reading all these comments I will quit this evil Zyrtec.... F 30 15 years

 4  seasonal allergies No side effects whatsoever. I really want to try and put some people's minds at rest because it seems the only people who ever leave ratings are people who have had freakishly negative experiences with a particular drug and this may well deter others from trying a drug which might actually help them. Zyrtec gave me ZERO side effects. F 46

 1  Allergies My daughter just started taking Zyrtec. Today the school called and said she was having a nervous break down. She is not the same kid. She is depressed, has anxiety, and talking about things a child her age should not even remember. I feel horrible for giving her this drug. She keeps saying "mommy I'm sad inside." I called the doctor and he said to take her off of it immediately. Why do they prescribe it if there is this many problems???? F 5 13 days

 1  Allergies Sleepy but I couldn't stay asleep for very long. Once I woke up I felt really weird. I felt like I was gonna have a panic attack or cry. A few hours latter I was sweating a lot and I became very cold. I also felt disoriented. Later that night I became very sick and thought I might even have to go to the hospital. It's two days latter and I'm still under the weather just not as sick. If I had taken any more whose to say I wouldn't have been dead. I only took one I didn't need another one to increase the negative side effects. I had to go to work the day I took it for the first time only to find out several people had similar side effects. Also only to find out they were still taking it but said they took it at night. This is not candy if you are experiencing these type of side effects don't play Russian roulette stop taking it. I would never recommend taking this pill there are other pills on the market or you could get allergy shots. F 34 1 days

 1  Seasonal allergies Extreme fatigue, restlessness, general anxiety, depression Ironic that the latest Zyrtec commercials show allergy sufferers getting ready to go golfing and bicycling after taking the drug since just one dose left me beyond exhausted within an hour. i cannot over-emphasize how tired Zyrtec makes me feel; I knew something was wrong because I never sleep during the day but I felt myself drifting off while driving, reading, watching TV and working. I could tell that if I actually let myself fall asleep, it would be the kind of deep sleep that goes on for hours but leaves you feeling groggy and disoriented upon waking. I don't know too many people who can take 12 hours out of their day to sleep! Luckily I bought the box with five pills because I will never take this drug again. I would rather sneeze 100 times per day than ever feel this low again. F 30 5 days

 2  seasonal allergies extreme exhaustion, headaches, body aches, flu like symptoms. Urinary tract infection This medication worked great for me for the first 5 weeks. Weeks 5-8 were absolutely horrific. I thought had a horrible case of the flu. My body hurt so badly I could barely lift my arms. I could barely work all day (sitting at a desk) and have to come home and sleep for 2-3 hours just to make it to 10pm. The light bulb went came on for me when I read that a side effect is the urinary tract infection. I had an infection 3 weeks ago and had not ever had one prior in my life (39 yrs). It was such a gradual change for me that I had no idea that it was the zyrtec making me feel this way, just thought it was the allergies... 2 days off and I feel amazing again... allergies and all... I'd rather deal with allergies than feeling that way ever again. F 39 2 months

 1  Allergies Horrible over the top anger about things that do not matter. I went into a rage at a drugstore because the sale price was not ringing up properly three hours after I took one single dose. So not at all like me. Horribly scary. I really understand how people can do horrible violent thing while taking this. This is a terrible drug. It should not be sold to adults or children as in instantly creates deep dark strange anger. It also exhausted me for days afterward. I feel as if I took poison. It makes me very afraid that I bought this the day it was recalled and it was still on shelves at Walmart. I would rather sneeze 60 times in a row than want to harm people and be a raving lunatic. F 37 1 days

 1  Seasonal Allergies I tried samples of zyrtec when it first came out to control my really extreme seasonal allergies. After only 2 doses I became extremely moody and aggressive and immediately discontinued use. I now use raw, local honey to control my seasonal allergies and have been symptom free for two years.

 2  seasonal allergies/sinus infections aided with allergy symptom relief, but eventually led to anxiety, depression, intense dreams/commonly waking up at night, thoughts of suicide and self harm I was suggested to take zyrtec daily for constant allergy symptoms I started getting from living in a large dorm in Boston. I initially noticed no side effects even though I had been told about negative symptoms from a friend that her younger brother had experienced. Only now, a year later, have I realized that some of the issues I've faced in the last year were most likely a cause of this antihistamine. Unfortunately, it has been the only allergy medicine that has worked for me, but was definitely not worth the hell that I went through this past year. I'm now faced with challenges of withdrawal as I've only recently stopped taking it but would recommend to EVERYONE to look into the very negative side effects and how to best stop taking this pill as SOON AS POSSIBLE. thanks to everyone else who posted.

 4  seasonal and pet allergies Maybe makes me a little tired. I have bad allergies and Zyrtec is the best; if I go off it, I am sicker than a dog within two weeks. Recently started Flonase, felt better, then thought I could give up Zytec. I have a sinus infection and asthma (just developed), because I went off Zyrtec -- now I am back on, and it is helping. When I'd tried to go off, after three days I was itching like crazy all over, but that only lasted a day and a half (I think until I adjusted to being off). Anyway, I obviously cannot go without Zyrtec. Not being on it makes me so sick; my allergies are so bad this time of year especially, but I need to take it all year round. F 49 5 years

 1  allergy My nine year old Grandson is experiencing side effects from the use of the generic brand (cetirzine)10 mg purchased by his parents at Walmart. He is having irregular heartbeat, mental and mood changes, difficulty breathing and tightness in his chest. I have addressed these problems with his parents and they blame it on behavior problems and will not take him off of this drug. Please help other children who parents relate everything to behavior problems that is clearly being caused by this drug. The Generic drugs should also be recalled, they have many bad side effects that are being ignored by parents. Please help to get the word out about the generic drugs too so they will have to recall them too. Do not give any of drugs to your children including the generic brand. They are all bad, stop blaming their behavior on ADHD, Aspergers, etc. It is the drug causing your children problems. Parents please wake up. I am doing what I can to get my grandson off of these drugs but unfortunately Grandparents have no rights. M 9 90 days

 1  hay fever/allergies Extreme mood swings, anger, irritability, violent behavior. My 9 year old son has been taking Zyrtec for the past few weeks. Until I saw this website with all the comments, we thought he was losing his mind. He has been extremely angry, irritable, and impulsive. He's been violent and lashing out at my husband and I, as well as our younger daughter. When we ask him what's going on with him, he began to cry saying "I don't know. I just feel so angry." Now I know that it most definitely has to be the Zyrtec. I can't believe this. This was recommended by his pediatrician too. I had a suspicion that the Zyrtec might have been an influence. I feel aweful that we've been giving him this drug and the anger has been the end result. I'm throwing this product out. Thank you to all of the other people who made comments. M 9 2 weeks

 1  Allergies Rapid heart beat, feeling jittery, inability to concentrate, anger, anxiety, emotional downfall. I originally started taking Zyrtec when I was 16-17 years old for seasonal allergies. I was not the same person. I was tired, moody, and generally felt "out of it". I stopped taking it after a couple of months and was fine after that. Since then I have just suffered with allergies because althought Zyrtec works the best- the side affects weren't worth it to me. Fast forward to 8 years later, yesterday I figured I would try it again as my allergies were getting really bad, and thought maybe something had changed in the last few years. After about an hour I started getting a rapid/fluttery heart beat, felt jittery, but also out of it at the same time. Could not focus on my work, and later when I met my mom, step dad, and boyfriend at a casino for dinner I got so anxious and irritated that I was holding back tears and anger the whole time. I was not the bubbly, funny, happy, goofy person I normally am. F 24 1 days

 5  Year round allergies I haven't experienced any noticeable side effects. I have been taking zyrtec for about 3 years. I am allergic to trees, grass, weeds, dust, mold, and animals. I had never been able to sleep with my mouth closed before I took Zyrtec. I also had very sensitive skin which was almost always itchy and would welt up when I scratched it. I couldn't wear any kind of lipstick/chapstick with color or flavor because it gave me a sore throat and made the area around my mouth turn red. Zyrtec has not completely cured my night breathing problems, but it has made them tons better. The biggest difference is that I am rarely itchy. it used to be that once I started scratching, I couldn't stop and sometimes, I would end up bleeding. I am so happy not to have to worry about that anymore. My skin still welts up if I scratch it, but I hardly ever do. I also don't have to worry about wearing chapstick or lipstick. On top of that, my seasonal allergies have gone away. Zyrtec has been great for me. F 21

 1  Dr. diagnosed - atopic dermatitis sleepy, irritable, angry, can't think clearly, illogical thoughts The side effects of this drug sneaked up on me. I thought it was one of those non-drowsy drugs so the sleepy lethargic feelings were blamed on the fact that I thought I was getting older really quick. I am usually a nice even tempered person and responded with rage to someone that I love for something that may have otherwise made me mad but not vengeful. I also lectured a man in the grocery store yesterday because he took too long to pick out his lemons. Oh my gosh -- who is this insane woman? After I snapped at a few other people today I tried to analyze what was going on with me. I remembered that the Dr had given me zyrtec for my itchy skin a couple of weeks ago. I decided to look at the side effects and irritability is not given as one of the most prevalent side effects listed by the drug company. Anyway, I decided to look further and found this website and was relieved to hear that I'm most likely not losing my mind but suffering from taking this drug. I'll not take it again and hopefully my nasty alter ego will go away. F 49 2 weeks

 3  Tree Pollen Allergy Severe mood swings, rage, thoughts of suicide, teeth chattering, shaking, cold sweats. I took two pills. The first time I ended up in a massive fight with a bunch of my friends and threatened to quit my job for no reason before nearly attempting to commit suicide. The next day I was very depressed and slept for 19 hours. The symptoms went away after two days and I blew it off as just one of those things. I took a second dose later in the week and slept for 14 hours, had mild hallucinations, and was in a walking dream-like state all day. When I got home I got into another fight and threatened to knife someone I didn't agree with while making irrational arguments over absolutely nothing. I then became so depressed and suicidal that if I had had anything poisonous in the house I wouldn't be here right now - it was like it sucked all of the light and joy out of me and all that was left was emotional anguish. I had cold sweats, shaking, teeth chattering. It was like having withdrawal from a narcotic, and that's when I put two and two together. I'm normally laid back, outgoing, and friendly. This drug needs a warning label. F 24 2 days
