| 5 | Allergies | mild fatigue doesn't even compare to the fatigue and nausea that would result if not taking Zyrtec | PLEASE DO NOT CONFUSE ZYRTEC-D WITH ZYRTEC. Zyrtec-D contains a decongestant which shouldn't even be available by perscription because it causes hyperactivity, anxiety and sleeplessness in almost everyone who takes it even short term. My daughter has seasonal allergies, and allergies to dust mites, which essentially means she's allergic all year. She has been taking Zyrtec for 7 years with no noticeable side effects. Before taking Zyrtec she would wake up every morning with an upset stomach from the drainage going into her stomach. Zyrtec absolutely stopped this. It may have have a mild effect of drowsiness, but without it she would be facing nausea every morning, sinus infections every spring and bronchitus or pneunomia every fall. She had to get off of Zyrtec for a week to undergo allergy testing and she was so nausiated she couldn't go to school. She developed a sinus infection that required two antibiotics to clear it up. Long term studies show this drug is SAFE. If your side ef | F | 14 | 7 years | 4/3/2008 | 5 | severe allergies, asthma | rarely dry nose, but a hell of a lotbetter than a runny one! | This medication is AMAZING for allergies! love it | F | 14 | 3 years 10mg 1X day | 5/10/2011 | 3 | Allergies Year Round | Dizziness, Vivid Dreams, Respitory Infection, Tiredness. | I've only been taking it for three days and i've already experienced really bad diziness and i have a respitory infection. But that means it is working because it's draining my nose out. Just the dizzy times are overwhelming and i've had verrrrrry weird dreams! | F | 14 | 3 days 30 1X day | 4/25/2010 | 3 | Seasonal Allergies | Been experiencing major fatigue, lethargy, depression, major weight gain, mood swings. | I took it for one week straight, then stopped for one day. That one day was terrible, have very sharp back pains and knee pains, migraines, terrible weakness. While on it, I have terrible thoughts, increase of sexual desire, urge to hurt someone. Will definately stop taking it. Do not give to kids/teens. | M | 14 | 1 months | 8/6/2008 | 2 | Allergies | Some drowsiness and trouble sleeping while on pill. When off of pill had extreme itching, sneezing, and some drowsiness | It works great against allergies, but when off of pill the side effects are unbearable. Only take this pill if you have no desire to stop it. The itching makes you want to scratch your skin off to stop it. I am going off of the pill now. | M | 14 | 5 years | 8/2/2008 | 1 | hayfever | moody, violent,spacey | M | 14 | | 6/2/2009 | 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 1X day | 1/9/2011 | 5 | allergies | dry mouth | Every day for the past 9 or so years. Absolutely zero complaints. | M | 15 | 9 years 10 MG 1X day | 1/17/2018 | 4 | dustmite allergies | Realizing that my son, age 15, has been experiencing sleepwalking, and it is getiing worse. He almost walked out of the house at night, and he has become frightened to sleep lest he sleepwalk again. | We are not going to take it for 30 days to see if it makes a difference. | M | 15 | 365 days 30 mg?? 1X day | 9/29/2010 | 3 | Dust mite allergies | None, actually, but I usually do not experience side-effects of any drug. | The stuff works great... Sometimes. And when it DOES, it's only for about a third of the time it says it should last. I have NEVER gotten 24 hours out of it. On the other hand, my allergies are pretty extreme. So I would recommend it to someone with less severe allergies. As for people like me, I'm planning on asking my doctor about something stronger. | F | 15 | 4 months 10 mg 1X day | 9/10/2010 | 3 | allergies | Everytime I take zyrtec, I get a weird pain in my right lung area. I'm convinced it's the zyrtec, because it's never happened before until I took it. | F | 15 | 1 days 10 mg | 5/17/2012 | 3 | Allergies | Even though the package says non-drowsy it still makes me super tired, I take it at night and it helps me sleep better but when I wake up I'm still tired! I feel like no one wants to be around me and I get random bursts of dizziness. It makes my knees ache more than they usually do too. It works great for allergies but the side effects are horrible. | F | 15 | 2 weeks 10mg | 5/31/2013 | 2 | Seasonal allergies | Tired, decreased energy. | F | 15 | 3 weeks | 6/5/2012 | 2 | Allergies | Depression, sleepiness, started having very violent thoughts,anxiety | I am off now and am already feeling alot better. Great for allergies, terrible side effects. MY withdrawal symptoms have been itchiess. Zyrtec messed up 2 months of my life!!! | F | 15 | 1 years | 4/24/2006 | 1 | Allergies (pet dander, seasonal) | Drowsiness, depression, mood swings | Seemed to work to control my allergies, but changed my behavior and made me tired all the time. Also, if I missed a dose, I would get a headache and feel nauseous until I took it again, kind of like a migraine. After I stopped taking it, people commented that my behavior had changed to what it had been a few years ago when I was not taking Zyrtec. I did get a free fleece blanket from Pfizer though, so now when I go into Zyrtec withdrawl, I'm not without comfort! I really think that these side-effects/dangers should be given to you by your doctor or pharmacy before you start taking the medication. The only way I was able to stop taking Zyrtec completely was to switch over to the CVS equivalent for a few months, then start taking that every other day, then eventually once every few days until I stopped getting headaches. I still have to keep a bottle of Zyrtec around because every once in a while I'll get sick and nothing else will make it go away. And also, my doctors assure me that it's not the Zyrtec, and perhaps I'm addicted to something else...whatever, I wouldn't take this if I could go back, Allegra would probably do the trick without the prolonged suffering. | M | 15 | 3 years | 11/26/2004 | 1 | allergies | fatigue, body aches, severe stomach aches, headaches, extreme anger, depression | My son started taking this at 26 months for 8 years. At the time, there was very little information about this drug on the internet. At every DR apt I inquired about side effects and every DR would always tell me they haven't heard of any negative long term ones. Well, if you or your child is taking this "poison" get off of it immediately. It will turn you into a devil. There is not enough time or space to describe the details, but my son would "zone" out and become extremely violent trying to harm himself and us. Fortunately, he was young and small enough for us to control. After 48 hours off this poison, he was a different person. He has been off this for 4 years and over time he hasn't had any meltdowns or anger problems. If you have a child taking this now and can't control their anger, stop giving it to them immediately. They might itch for a week or 2 but that can be controlled with Benedryl until the zyrtec is out of their system. Zyrtec should be banned. It is a horrible medicine. | M | 15 | 8 years 1X day | 6/14/2013 | 1 | Seasonal allergies | Depression, anxiety | I've been taking Zyrtec from the age of 6 when it was a prescription and have taken it for about 7 years. When I was young, the medicine worked well and I could notice a difference when I stopped taking it but as I got earlier my body may have gotten used to taking it everyday because then it stopped working. Last year I started taking Allegra D, and that worked fantastically so this year I thought I might start Zyrtec again because it's cheaper for the most part and easier to swallow without water (when i forget and have to stuff one in my pocket to take on the go). I bought Zyrtec about a month and a half ago since the weather warmed up realllyyyyyy early this year and started taking it. Ever since then I experienced mass amounts of depression. not sure if this is soley related to Zyrtec but I did relapse into a cutting habit I gave up 2 winters ago so I figured it was because something triggered my depression again. | F | 15 | 30 days 60 2X day | 4/4/2012 | 1 | asthma | Runny nose, bloating in the face, depression, nightmares | I had taken zyretec last year for 4 months after i had a horrible asthma attack. within those 4 months, were the worst times of my life, I felt very depressed, and at one point had thoughts of suicide, im 15 years- and am still growing in height and noticed that my natural speed of growth had stopped dramatically, (i was 14 at the time when i was taking it). Any time i took the medicine i would wake up with a bloated face- even my friends in school noticed the change in my face (my self esteem lowered big time). My nose was constantly runny- and i had huge exams- so the outcome, as you can see, didnt go so well, yes, it helped my breathing, but id rather not go through those 4 months again. I also do recall having some terrible dreams. I dont recomendend this medication for anyone below the age 18, atleast it is what i think, since i am younger i had a higher risk of many side effects. Now that i have stopped using it, and switched back to singular, my face went back to normal, my nose isnt runny, my height hasnt changed- it takes a while for your natural growth to take back its place in order( by the way my parents are very tall- my mom is 5'7 my dad 6'0, i dont believe it is a gene thing) , and the bad dreams i was having no longer exist. | F | 15 | 4 months IDK 2X day | 7/13/2011 | 1 | seasonal allergy | I Purchased OTC Zyrtec for my daughter as per her doctor, she took the Zyrtec for a little more than 2 weeks. The caughing and sneezing became worse with asthma like symptoms. She was having a reaction to the medicine. I took her off Zyrtec and within a day the asthma symptoms started to clear up. Her breathing became better and the caughing subsided. | If symptoms for taking Zyrtec do not get better in a few days, but seem to get worse, consult your doctor right away. My daughter was on the edge of having a severe asthma attack while on Zyrtec. | F | 15 | 2 weeks | 4/7/2009 | 1 | Allergies | Daughter was angry all the time, moody, flash temper, no patience for anything. | My daughter started Zyrtec when she was about 13, she became terribly angry at everyone and everything. We blamed it on hormones, peer pressure, etc. etc. She is now 15 and we just heard about theses problems with Zyrtec 8 days ago and you would not believe the change. I have my sweet daughter back! Not that there still aren't typical teenage drama etc. but she had become down right mean and nasty. I wouldn't let anyone take this medicine. | F | 15 | 2 years | 3/5/2009 |
