| 1 | Chronic Allergies | Severe moodiness, mood swings, easily aggitated, groggy, cloudy headed, extremely tired. | I am 5 months pregnant and my allergies worsened so I was put on Zyrtec. Talk about mood swings.. and hormones surges. I cannot believe that my doctor did not warn me about this. After 9 days and two horrible fights with my husband I took myself off of it. I would rather suffer through the allergies than experience these side effects. | F | 35 | 9 days | 2/14/2005 | 1 | Sneezing, swollen itchy eyes | My ped gave this to my 20 month old son for his allergies. He turned into a uncontrollable child. Screaming, having temper tantrums, kicking, hitting. I thought, Oh no terrible twos are going to be horrible. We took him off of it and he is back to a normal 2 year old. I do not recommend this at all. | F | 35 | 3 weeks | 5/19/2005 | 1 | seasonal allergies | I started taking zrytec and only had runny nose tried to stop after a year and experience hives which I never had before and am force to continue to take it or suffer I am in worse shape than when I started out drys out my skin and mouth and eyes quitting taking this medicine is worst than when I stopped smoking it is addictive and I was never told that | F | 35 | 4 days | 8/10/2004 | 1 | Allergies, Sinusitus, Eczema | Extreme Fatigue, Confusion, Dizzyness, Blurred Vision, Inability to Concentrate, Forgetfulness, Severe Itchiness upon stopping | Worked great for two months then side effects took over. Was in a constant "fog", unable to concentrate, mistakes at work, unable to fall asleep and stay asleep at night, basically made me into a zombie. I've been off for 5 days now and now have severe itchyness all over my body (seen the term "Zytec Withdrawal", checkout - http://zyrtecwithdrawal.blogspot.com/) Not worth it. I will never will use again. | M | 35 | 3 months | 10/20/2008 | 1 | allergies | My WONDERFUL 10 month old daughter who would laugh even when sick turned into a HORRIBLE child in one day after taking ZYRTEC. She started having temper tantrums that involved slamming her head on the floor (or toys) and hitting and biting.... I have been taking it for several years and now wonder if that is why I am seeing a therapist and my hair is falling out. DON"T TAKE IT! | This medication should NOT be recommended for children!!!!! | F | 35 | 3 days | 4/23/2006 | 1 | Allergies | Hugely increased appetite and consequent WEIGHT GAIN. | I had to go off of this medication after gaining over 10 pounds in 6 months. I was always hungry, even shortly after eating. It was crazy and although the medicine helped my allergies, it wasn't worth constantly feeling hungry and gaining all that weight. It should be added as a warning on the label. Also major headache the first couple days off the medication. | F | 35 | 6 months | 7/5/2006 | 1 | Dust mite and mild cat allergies | Erratic behavior without recall, irritability, WEIGHT GAIN (25 lbs in 8 months — with regular, vigorous exercise and healthy eating habits). N | I have never had problem losing weight if I happened to gain any for any reason. I have been struggling for months to lose and have in fact continued to gain instead. My wife and i have been arguing over meaningless issues. We thought b/c we have a baby coming and the stress of our first child coming, but this makes no sense b/c we're both thrilled and excited about it... I stopped taking Zyrtec Thursday and we haven't even so much as disagreed about anything, much less argued to any degree since. I have had a few episodes of erratic behavior. One night my wife asked me for an ice pack. I brought her a wet paper towel and was insisted that's what she asked for — then went straight to bed without getting her ice! This is EXCEPTIONALLY ATYPICAL behavior for me. **I did not remember this the next day. It was like I was acting in my sleep. Another time she asked me for ice and I brought her a bowl of soy milk, hoping that she could explai | M | 35 | 8 months | 3/9/2008 | 1 | allergies and sinus infections | palpitations, feeling disconnected, euphoria, dizziness, hallucinations, weird dreams, mind racing, insomnia, frequent urination, spaciness, OCD, reckless behavior, fast and uncontrollable rage, anger, crying, itching upon withdrawal...depression, OCD, cramping, nausea, extreme tiredness, pain everywhere, inability to focus, loss of motor control, disoriented, waking REM, headaches, itching | This is a dangerous drug. I am so sick after taking this. I stopped taking it two days ago, and I feel so bad. A few years ago, I took a anti-epileptic drug (a dangerous narcotic) called Lyrica and almost lost my life. The side-effects and withdrawal that I am experiencing from Zyrtec are similar...although not quite as profound. I almost got in several car wrecks over the past few days...I hit my dog (hard) for no reason except this fast, uncontrollable rage that came out of nowhere (I love my dogs and would never hurt them)...I can't quiet my mind...I'm so tired and can't sleep...and I'm just not thinking straight. This is a scary drug. Please be careful. Before taking this, I was doing well in life...healthy, happy... Just be careful. | F | 35 | 2 weeks | 2/15/2008 | 1 | Chronic Hives | Dependancy, severe itching, muscle tightness, headaches, joint pain. | It took me nearly 15 years to discover a doctor that could actually cure my condition. Zyrtec was not the answer. I was able to stop taking it after a couple weeks after taking a specific natural supplement regimine and altering my diet. Zyrtec starts out like a wonder drug then gradually steals your health until you have to do something else. Unfortunately by that time it is really hard to wean away from it and repair the damage. I went to www.drmagaziner.com and they were able to find the cause and the cure so I didn't need Zyrtec. I would suggest seeing a Doctor that specializes in that type of treatment - your ordinary dr. will tell you you are fine and will not run the necessary tests that are needed to find the underlying problem that Zyrtec causes. | M | 35 | 4 years | 7/9/2007 | 1 | allergies | Racing heart, anxiety, sleepless nights, irritable and feel like I'm on a bad upper. | Not a good medication; I'm hesitant to take medications unless there is a true medical need. My allergies (red eyes specifically) have been going on for years; finally broke down and tried something (doctors advice). This drug felt like poision in my body. | F | 35 | 5 days 10 MG 1X day | 9/6/2013 | 1 | Allergies | I have had crazy itching to the point of ripping my skin open, mainly on my belly and rear end. However my whole body itches. I have also had a bout of depression, to the point of crying. I felt like living wasn't worth it. Have headaches often. I stopped the medication last night and CAN NOT WAIT for it to leave my system. I want to be itch free!!!! | I'm sorry I ever took this medication, The makers of ZYRTEC should pull this drug off the market, its a shame they will allow people to go through these symptoms! | F | 35 | 1.5 months 10 mg 1X day | 10/20/2012 | 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 zyrtec-d 1X day | 6/27/2012 | 1 | allergies | My 6 year old has been on zyrtec for a few months, and I am horrified to read the responses - the behavior, irritability, nightmares, intense anger, moodiness, yelling, just general nasty problems we've been having, our lives our upside down over this. A couple weeks ago, his dosage was increased to 2 tsp - the allergist said the only side affect was tiredness! I feel horrible, thinking the hell we've been through could be a result of zyrtec?! I am thankful I found this site today. Tonight I am dropping his dose to 1 tsp and then in a day or two 1/2 tsp, and then off, to see if his emotions improve. | F | 35 | 5 months | 3/25/2007 | 1 | allergies | Although I have not had any allergy issues while on Zyrtec, the weight gain and bloating I have experienced has been alarming. I have also suffered severe lethary. These side effects really hit me these past two months of my six months use. Not worth it. | I am off it. Two days... itching, nausea. Cannot wait for it to be out of my system. | F | 35 | 6 months 20 mg 1X day | 3/26/2010 | 5 | Severe Allergies | Very sleepy, cranky/crabby, had a hard time staying focused on duties while at work. Wasn't sure if it was Zyrtec or Singular that was causing the sleepiness. Stopped taking Zyrtec for 1 day found that my Allergies were Severe after the last dose wore off. The sleepiness wore off though..... Took 1 dose of Zyrtec and did not take singular was very sleepy, allergies were not as severe when going off of singular since Zyrtec was in system but found that the combined use was the best and most effective for my Severe Allergies. | was tired of being tired..... Then I had an idea and tried.... eatting something, taking dose of Zyrtec then going to bed. When I woke up the next morning, I was actually not sleepy like I was use to being after taking Zyrtec/Singular. My nature is normally one where it takes a litte bit to wake up, but now, after a cup of coffe (strong when asthma is really bad) I function wonderfully through out the day. I've been doing this nightly ritual of eatting a little something before bed, take Zyrtech/Singular for at least 3.5 months and I've become a highly productive individual. At work, I'm actually now doing the work of 2 people and am able to keep my head on straight with no sleepiness so that I can work on complex things and multitask at the same time. I'm so excited that I can actually do my normal duties and then some, while not being bothered with my servere allergy complicaitons. I feel like I'm a normal person for once. Try my nightly ritual and see if it works for | F | 36 | 4 months | 9/20/2005 | 5 | Severe Allergies | responding to person with smell complications. I did have this as well - until I did my nightly ritual of eatting something, taking Zyrtec/Singular then going to bed. | I now have one of the best noses around and can smell things that most people can't without any queeziness. My sense of taste hasn't really changed, at least nothing noticably. | F | 36 | 4 months | 9/20/2005 | 5 | Recuring Hives - unknown allergy | Occasional drowsiness. | 1 pill/day 10mg taken in the morning. I have been very pleased with Zyrtec's ability to keep the hives away. I still get redness and hot patches (skin gets very hot to touch) where the "itchy hives" would have been. When the Zyrtec starts wearing off, the "itchy hives" come back. Occassionally, the hives falre up badly and I have to take an extra Zyrtec and a few times had to dose way up on Benedryl. Benedryl seems to help far better during severe cases when I get a snout full of whatever my allergin is. Zyrtec is not a cure. It is a suppressant. | M | 36 | 9 months | 3/17/2007 | 5 | allergies | F | 36 | 2 years | 11/5/2002 | 5 | terrible allergies | Just drowsiness for the first few days. It passed and I don't think I've had any problems. Taking it for years. Excellent med and now OTC generic. | I think overall it's probably the most effective allergy med out there short of shots, steroids, etc. I have terrible allergies - dust mites, pets, etc.- and all the other stuff did nothing for me. The reactions I'm reading from small children are probably related to adjusting to the drowsiness; children can't handle that as well as adults (I have four children...). My kids were on and off of it for years and I never had problems. IMHO I think a lot of the bad experiences mentioned here are coincidental and not related to the Zyrtec. | M | 36 | 5 years | 1/16/2009 | 5 | allergies | excessive weight gain! | Zyrtec really alleviated my allergic reactions (environmental and food allergies) but I gained approx. 15 lbs within a few months of being on it. | F | 36 | 500 days | 5/29/2008 |
