 4  Allergies Slightly drowsy during the day but not nearly as bad as benadryl. Performs as advertised but still makes you a little sluggish during the day. My advise is to always take it at night before bed. M 56 3 months

 1  Demographism, Hives and Allergies Everything everyone else said is absolutely true. This drug may help with the severe itchiness and hot feeling underneath the skin and hives but the side effects are truly unbearable! - It shuts me down for at least two or three days! I truly cannot function while on this drug. I experience extreme fatigue and it is impossible to function. It is a terrible state of mind to be in because you need to live your life and do things. With this drug, your emotions are all over the place because you wonder to yourself, what is wrong with me? You cry, you feel as though you're going crazy and you can't function and you have things to do. It totally shuts down your life. It's like a mind control type of thing. All you can really do, is sit there and feel totally, totally out of it and feel down, super, duper groggy and depressed and hopeless. - I feel this way whether I bite a piece off of a pill on take the whole thing. This pill totally controls your life. - - All of this, just to try to g It's a shame that a drug whose milligrams are so small, could cause such a huge effects of tons of people and the manufacturers and Food and Drug Administration would not do anything to make them edit the drug to prevent these horrible, horrible mind and body controlling effects. All of this simply to prevent itching. - What a shame! - What's even more, is that right now, I have no choice but to take it . . . because I suffer so badly with the demographism and hives. F 50

 1  My son's seasonal allergies My son, age 7, has been experiencing extreme anxiety recently, including feelings of paranoia, stress and worry. It's been frightening! He's been taking Zyrtec for about a month and although it helped his allergies, it's changed his personality. We have stopped Zyrtec and are hoping he is back to his happy self soon. Please remember to contact the FDA with any drug side effects. They can be reached at www.fda.gov/medwatch or 1-800-FDA-1088. The makers of Zyrtec need to know the harm that their product can cause.

 1  Allergies Made me near comatose tired! Cotton mouth heart racing and general feeling of malaise. I tried a half dose and it was just as bad. After losing two days of my life to this junk medication I decided the symptoms were less horriffic than the supposed treatment. This is the most horrible medication I ever have taken and should be taken off the market. F 2 days

 1  Allergy Only took small doses before bed. Woke in night dry mouth,strange lights in vision. Next day couldn't see properly, crying all day, feel disorientated all day, feel absolutely dire. Ranitidine did the same and this has similar ingredients. These drugs must affect the neuro system, all to treat allergy and indigestion! Absolute disgrace these over the counter drugs want banning.

 4  allergies Zyrtec can put you into the biggest raging frenzy. you wont be friendly or patient and you wont know its happening either! this is a powerful mind altering drug, you can completely dissociate and not realize how you are acting until you come out of it! there are some GOOD things about zyrtec, it works very well for allgergies and itching, sneezing, swollen eyelids, runny nose but it can also knock you out like nothing else! you will have a incredible unconcious desire to sleep, for 10-14 hours. sometimes after taking zyrtec i lose 2 days! your body will just want to switch off. its my theory that zyrtic is an incredibly potent stimulant that acts on the nervous system that supresses a lot of self control.

 1  Seasonal allergies The Zyrtec cleared up my allergies just fine....it was the severe side effects that was horrible! It was not a big deal that I was tired while taking it. What was a big deal was my mood. I felt like I was going crazy. I had no idea it was the Zyrtec. I was totally lost. My anger was out of control, one minute I was yelling and the next minute I was crying. I felt hopeless, and I didn't know why. I decided to stop taking it, and the itching started on my feet and legs. I am so happy to start feeling like myself again. I cannot believe the effect this drug had on my mind. I rarely cry, and found myself totally miserable. This drug should be banned. It is a serious mind altering drug. I am thankful that I was able to realize that this drug was causing my distress. So happy to be me again, even if my nose is running. Dangerously mind altering drug. F 49 10 days

 1  Seasonal allergies Gradual defiance, anger, rage...Jekyll/Hyde behavior, only minor allergy relief At first it seemed to help. On day 3 he started acting out a little. I just thought he was having an off day. For days 4-9, temper tantrums over irrational issues began and progressed. He was hitting, kicking and throwing things and also hitting himself. He even tried to choke me and he doesn't see that kind of behavior to know this. After he finished his moment he seemed remorseful like he didn't realize he had gotten that way. He stopped taking Zyrtec and almost 48 hours later he is back to his normal sweet self. I plan on using a more natural alternative as he needs it. No more Zyrtec!!!! I wished I realized it sooner so he wasn't in this agony for so long. M 2.5 9 days

 1  Swelling and unknown itching This is the most horrific medication I have ever been on and has made me even more afraid to take pills.....Parents please don't give this to your children I started taking this after my allergist recommended it for my unknown itching and swelling. starting out everything was fine, my symptoms vanished and I felt clear.. On the sixth day of taking this I forgot and after that all hell broke lose.. I couldn't sleep lost my appetite I was afraid and paranoid to be alone I couldn't sleep alone and usually i enjoy my privacy. After not being able to sleep for four days I became depressed cried every day and developed lightheadedness on my left side. A week later and it still has not subsided ... Honestly I'm terrified of the damage this might have done to me and won't be able to see the doctor for another two weeks.All in all just STAY AWAY F 17 7 days

 1  seasonal allergies My 9 year old son started taking Zyrtec 2 weeks ago after seeing our pediatrician because of seasonal allergies. my sweet, happy, smiley, energetic boy, changed…literally, overnight...he’s a completely different child. In the last 2 weeks he's become very moody, extremely anxious, fearful (to the point of being afraid of dying), lack of appetite (lost 8 lbs in 7 days), irritable, trouble sleeping, complaining of tightness in his chest, trouble breathing, aches, stomach ache, and body aches. He’s been extremely moody and cries out of nowhere. He had a complete, what looked like a panic/anxiety attack this weekend saying "something is wrong but I don't know what's wrong with me!!" He’s very angry and lashes out the family but will quickly turn around and apologize. He's always VERY sweet to his little sister but during these past 2 weeks he can’t even look at her without being upset and wanting her to go away and pushes her away. After 2 weeks M 9 2 weeks

 1  Allergies in Austin I took it at night and it made me sleep a lot, woke the next day feeling tired, drained, weak, and unable to fully wake up. I felt like I was in a awake coma. I started feeling extremely depressed and negative. I was unable to accomplish anything that day or get anything done, because I was so weak and drained. F 35 1 days

 3  seasonal allergies High feeling, inappropriate laughter, wooziness, fatigue, loopy behavior, saying inappropriate things that offend people, confusion, slow reflexes and dropping things, making errors of judgment The drug works well for allergies, but the damage it does to my social life is not worth it! I'd rather itch than be so inappropriate--it's like it turns me into a rude drunk. F 44 1 days

 1  Seasonal Allergies Extreme Anxiety and disassociation from my body. I'm the happiest guy in the world. I've never had any issues with anything or ever felt depressed.. EVER. I'm in my 40's. After the 3rd season, taking this stuff.. I had an Anxiety attack.. and then thought I was like disconnected from my body for a while. I didn't know what it was. I thought I was having a Heart attack. I'm not normally a dramatic person.. but it freaked me out, so I went to the Doctor. He said I'm in perfect health.. and then asked me if I was on anything. Only the Zyrtec. He said, in some rare cases, people can have my symptoms and to stay away from it. I haven't touched it since then and I'm back to normal. Weird. I just thought somebody should know, just in case it happens to them. M 43 14 days

 5  Allergies If take full dose (5 mg) he gets very hyper..if takes 2.5 mg in am and 2.5 in pm have had no problems Please note I see a majority of these reviews show 1 x daily..wonder they are taking the 24 hr or just the 12 hr dosage...this can make a difference as one has psuedophedrine in it for adults..as for children..if I see a product working but side effects (if not dangerous) then I try to break the dose down so they are metabolizing a little at the time not a full dose.. remarkable how well it works when do this M 3 2 years
