 1  seasonal allergies Irregular heartbeat, sleeplessness, shaking/tremors, weakness, mental/mood changes, dizziness, anger/rage,floating sensation.It even affected my blood sugar level.These are very concerning side effects. I stocked up because of coupons. Have been taking for about 2 years. Stopped about 3 months ago and started up again last week and noticed all the symptoms back again after the first dose. Then I knew all my symptoms were from Zyrtec. I want to return the rest but Walmart won't refund my money.How can I get reimbursed for the rest of them? F 35 2 years

 1  Allergy to dust and mold I'm generally a very calm person but by my 3rd dose of Zyrtec, I became a raging lunatic. I have never in my life felt so angry. I had absolutely no control over my emotions. It got so bad- I had to leave my home and stay in a hotel overnight because I didn't trust myself for fear I would hurt someone. My husband of 20 years was blown away by the effect ths medication had on me since I am the calm voice of reason in our family. The intense emotional reaction lasted about 18 hours. For the next 2 days, I felt as though my brain was "bruised" with a dull pain on the right side. It took 4 days to completely recover. The FDA should investigate the complaints and undertake a complete benefit risk analysis. There are so many alternative allergy medications available, if indeed many others are experiencing the same adverse reaction (rage) the drug should be pulled from the market. F 51 3 days

 1  Allergies Nervousness, volatile, easily annoyed and enraged, generally irritable, frequently irrational and sometimes – down right psychotic. This drug, as well as Claritin and any other antihistamines for that matter (and their respective generic brands), are incredibly dangerous and destructive to some sensitive people’s psyche and emotions, and should carry MUCH STRONGER warnings of these risks. The problem is that they work well in addressing allergies – so a person is anxious to get that relief; however, to some of us sensitive people, they cause an underlying feeling of nervousness, make you volatile, easily annoyed and enraged, generally irritable, frequently irrational and sometimes – down right psychotic. I am so grateful that after 10 years of struggling with these periodic and totally uncontrollable emotional issues, my beautiful new boyfriend made me realize that it was the antihistamines causing all of my behavior issues. OMG – I FINALLY HAVE MY LIFE BACK!! Do some research on the Internet – the link between psychotic behavior and antihistamines is well documented. Since stopping these drugs, I am back to the calm, rational, loving and reasonable person I used to be. DO YOURSELF (and your loved ones) A COLLOSAL FAVOR - if you are taking any antihistamines – get off of them immediately. Instead, address your allergies with a saline nasal rinsing system (I do it up to 3 times a day – every day) like the SinuCleanse, readily available at Walgreens and CVS. I also use allergy drops in my eyes, when necessary. I am forever grateful to my loving partner for F 48 10 years

 1  seasonal allergies I took this on and off for years after claritin stopped working for me. I have also battled episodes of intense anger and depression for years. I finally put it together with the zrytec after my second child. I stopped taking it for almost a year due to mild allergies season and started again. I became downright abusive to my husband and children. I had no patience only intense rage. I misplaced the pills and was finefor a week. Started them again for 3 days and the rage came back. I tried this 3 more times for different lenghts of time until I concluded it was the zrytec and stopped. I had no rage or anger for the following few weeks and havent since. I am trying to repair the damage with my children fromthis stuff. It did work controlling my allergies and has been the only drug successful at that so far but I will never use it again. F 41 1 years

 5  Indoor and Outdoor Allergies No side effects at 10mg. Higher doses tend to make me sleepy. This is the best antihistamine for my allergies. I only take it during bad allergy season or if I am cleaning the house (dust allergies). I have tried both name brand and drugstore generics, both work well. F 40 5 years

 1  pet allerigies extreme lethargy, insomnia, weight gain, "foggy feeling", dizziness, irregular menstrual cycle, depression, anxiety, irritability Stopped taking this drug 1 week ago. My brother was battling with severe seasonal allergies and I recommended that he take Zyrtec daily because it works very well for my allergy symptoms. 2 doses later he started complaining of all these symptoms that I had been battling with for years. Since quitting I have lost 4 pounds, have way more energy and I actually feel like I am happy again. The itchiness is uncomfortable and my allergies are bothersome but I would trade that for feeling happy again anyday. F 30 3 years

 1  Seasonal Allergies inside and out zombie-like state, severe feeling of disconnect, inability to concentrate, poor motor skills, confusion, extreme tiredness, constant yawning, feeling of being in "slow motion". I just developed seasonal allergies for the first time this year, so I was not familiar with the brands. I purchased a generic form of a Benedryl allergy pill but found I had to take it too many times a day, it was too weak. So my doc suggested Zyrtec and both he and the pharmacist said it's "non-drowsy" and works great. Well, I only took it for two days and that was one day too long. It turned me into a virtual zombie (which lasted into a third day after I had stopped taking it). Not only was I extremely tired and lethargic, but I couldn't concentrate on even simple things. I would literally stare at a word on my monitor for several seconds trying to comprehend what the word said. It messed up my motor skills so typing was difficult, and I was extremely distracted and disoriented. I've never experienced such bizarre side effects, it really zonked me out and rendered me virtually useless. I also felt like I was moving and thinking in SLOW motion. It was awful. I'm not even attempting a lesser dose, I want nothing to do with this drug. FYI: I am not typically sensitive to drugs either and rarely feel any side effects of typical medications. PS: Yes, it did eliminate the allergy symptoms by the way, but the relief was in NO WAY worth feeling like a mindless zombie. F 39 2 days

 1  Seasonal Allergies while hiking I just started suffering from a non stop runny nose while hiking in the local mountains. I first tried Clariton which stopped the runny nose but I noticed I felt wobbly while hiking at altitude which is not safe so I tried Zytek hoping for and improvement. Not only was the 24 hour pill WORSE it could have killed me. I was leading a hike up a mountain I had conquered many times before and the Zytek made me nauseous, severely weak, tachcardic AND dizzy. I was unable to finish the hike on a very hot day and risked dying going by myself to the car. Even the down hill was an extreme challenge. It is going in the trash! F 44 1 days

 1  Allergy To Bug Bites My normal cheerful mood changed so much that my friends and family commented on the change. Almost everything made me mad! I had loss of appetite and nausea and in general, just felt bad. I couldn't really attest that it helped with my bug bite reaction either. I normally walk a mile a day and don't have any real aches and pains but my knee joint started hurting two days ago and after doing some research on Zertec I will never take this again. I have almost returned to my normal self, hopefully I didn't take it too long. This product is just not worth the side effects to me. F 65 14 days

 2  allergies easily angered, angry, near violently angry - I'm an old woman who likes people and I said MF... the swear word... for the first time in my life and then I sulked because I knew they didn't hear me... crazy mood swing... sleepiness and foggy brain (could be allergies), and piercing headache to forehead... I thought I was stroking out... fortunately this is fourth time I've experienced a medication induced personality change/reaction.. I stopped the zyrtec immediately. I started on zyrtec because claritin ( 9 years of seasonal use) seemed to fail... something that happened with a previous med that I used seasonally for years. At the pharmacy, I asked for suggestions and was told to try zyrtec. It immediately did relieve my allergy reactions... which was nice... but the side effects were horrendous. Luckily for me, over the many years I have taken meds and did diets, I have had adverse reactions and knew after I thought about it ... that my personality change... extreme anger, vocal expressions of annoyance, and depression... was not ME. I am stun by my inability to control angry impulses over the last two days I took zyrtec. I only recognized the problem about 4 hours before I was goin' to take my next 24 hour pill. I was taking a over-the-counter dose.,,10 mg. and my adverse reactions started on the second day... I only used it for three days total. I'm goin' to be sure to include zyrtec on my med allergies 64 3 days

 1  Allergies When I decided to discontinue taking Zyrtec, I experienced unbearable, continuous, incapacitating itchiness. My entire body was covered was covered with large welts and even loose clothing caused painful hives to erupt . There are no words to describe the suffering involved. I took cool showers and used cortisone ointment to no avail. I finally had to start taking Zyrtec again to stop the suffering, which was acute. I called the manufacturer of Zyrtec for advice on how to get off the drug, but the representatives I spoke to on two occasions said they had never heard of any side effects from quitting the drug. In the meantime, I'd checked the Internet for information about Zyrtec withdrawal symptoms, and there were literally thousands of comments from other people who had suffered incapacitating itching when they they tried to discontinue---some after taking the drug for only a short period of time. Without any guidance from the manufacturer, I reduced the amount of the medication very gradually from three-quarters of a pill, to half. This took me about two years to accomplish. Now, three years later, I'm down to one-quarter of a tablet once a day. It has taken that long to almost get my system rebalanced! I hope I can get off this drug completely. I think it's criminal that there aren't warnings about discontinuing this medication Worst of all, I was offended and angered by the arrogance of the manufacturer who said through their representatives that they'd "never heard" of anyone suffering from discontinuing the drug. Apparently, most doctors have also been misled about Zyrtec and believe it's benign. Buyer beware. F 68 9 years

 1  Seasonal allergies Anger, fatigue, emotional outbursts including crying and yelling, clothes and hair bothering her, stomachache. My daughter has taken Zyrtec (generic) as needed for a couple of years. This time around, she had been on it for about a wk or so but still complained about her allergies. We also noticed her fatigue and thought that she might have a virus but we kept her on the drug. I even slightly increased the dosage this wk (per her doctor's orders) and split it so she took some in the AM and some in the PM but she still was complaining about not feeling well. This wk she has been very emotional over minor things and started to complain about her stomach hurting. Then, she said, "I am mad but don't know why." Later, she said she went to her room and felt like throwing all of her stuffed animals off of her bed, but didn't have any explanation as to why she would want to do so... She is normally a very laid back and go-with-the-flow type of child so this was concerning. She even said that her heart was beating very fast. I quickly took her off Zyrtec & called her doctor, who simply suggested a different drug because of the fatigue & didn't acknowledge the behavior issues. Last night, after being off of Zyrtec for almost 24 hrs, she said she didn't feel well & she didn't know why, thought her heart was racing & asked if she could go to the doctor in the AM. That was it. We immediately went to the ER of the local children's hospital where she had an EKG that was normal. The doctor there said he sees this problem all the time with antihistamines in children. He stated that some children just go off the wall crazy with them & that it would take a few days for her to return to normal & that if she wasn't better by then to see her dr. That night was horrible & it was almost midnight before she could calm down enough to sleep. Her clothes were bothering her & she was worried about everything. Tonight will be 48 hours w/no meds & she seems to be doing better today w/only one small crying incident about her hair, one time where she said her pants made her feel bad (angry) & one time she said she was mad at her sister & blamed the meds. (LOL) I just want my girl back. I hope this helps someone else. F 7 3 weeks

 3  Constant runny nose, allergies Doc recommended Zyrtec after a combination ear infection and sinus infection, so I started taking it every day. Been dealing with some really bad anxiety, depression, and constant fatigue and lack of motivation.... Ran out of my pills one day and got lazy about taking more, so I just stopped. Slept like crap for a week (withdrawl?) but suddenly realized I wasn't NEARLY as tired as I used to be, and have a bit more motivation to do things now. I'm convinced it was the Zyrtec. Worked great for my allergy issues, but it's not worth it feeling like a worthless zombie EVERY SINGLE MORNING. F 30 2 years

 3  Severe allergies,indoor/outdoor Severe vaginal dryness with cracking and bleeding of skin with bumpy rash in and around the pubic hair. Ear infection and itchiness of the ears. I am posting this side effect because it is NOT listed with the other side effects that people are posting. I have noticed weight gain as well. The reality is that I already had trouble with my vaginal area and I believe this drug increased and caused new issues. I have not had a sinus or ear infection in about two years, developed an infection in both ears which has lasted for about two weeks, ears are severely plugged and I have been woken up the last two nights with extreme itching in my right ear and much itchy discomfort in the vaginal area.

 5  allergic asthma, hay fever, asthma dry mouth Zyrtec has made my asthma much easier to deal with, with other medications added, such as singulair and a steroidal QVAR inhaler daily, my allergic asthma is much more controlled. The lung specialist I was seeing wanted to place me on Xolair injections for severe, uncontrolled asthma, when I learned there was a slight chance of anaphylactic shock and cancer in clinical trials, I decided against the injectable. While taking the Zyrtec I am now able to have my 2 dogs in the house and love on them without breaking into hives, as well as eat some foods, which I use to react badly to. F 40 2 years
