| 1 | Allergies | My 11 year old son's usually agreeable personality dramatically changed. He slept until 8:30 am when he always gets up around 7am and then proceeded to yell and be disagreeable all day long. He even called me names he has never dared use before! When I read about the medication and realized it might be a factor talked to him about why he was behaving the way he was. He apologized and said the medication made him feel "out of control" when he got angry. | Unbelievable that a pediatrician had prescribed this for mild allergy symptoms! I hate to think of all the children out there who are taking this - this should be taken off the market in my opinion. | M | 11 | 1 days 1X day | 6/27/2014 | 1 | seasonal allergies | My 2.5 year-old son started behaving very abnormal after 2 days on it. Very irritable, cranky, crying with no reason, hitting his head on the floor, hitting us....completely the opposite of what he normally is. | I can't believe our pediatrician recommended this. | M | 2.5 | 3 days 5 mg 1X day | 6/25/2014 | 1 | Seasonal allergies tree pollen | Depression, easily agitated, angry for no reason, tired all all the time, hair loss. I started taking this 6 years ago for 4 months out of each year for pollen allergies. Each year I realized in the spring and early summer I would become a mean angry depressed person who didn't feel like doing anything. My hair also falls out a lot. Also each time I stop taking it I have intense itchy skin and scalp for 2 weeks or so afterwards but my mind clears up and I feel better mentally but the physical withdraws are terrible also I cannot sleep at night once I stop taking it. I will never take it again I cannot deal with the mental symtoms from it anymore it effects me and the people around me. It worked great for my Sneezing and itchy eyes but the side effects and withdraw are not worth it anymore. | F | 25 | 6 years 10mg | 6/15/2014 | 2 | Dust mites, animal dander | Serious behavior issues. 8 year old daughter was prescribed singulair first and we went off that because of extreme mood swings. Tried zyrtec next, it wasn't as bad as the singulair so we continued it. Issues at home started increasing, lots of crying, anxiety, and physical anger issues. Her reaction to everything was so extreme. 3 months after starting zyrtec, her report card came home. Where she normally had +'s in behavior, she had -'s now! Teacher commented about her being distracted and not getting work done. Extremely unusual for her. | I believe it worked well for allergies, not sure as it may have been the work we did in the house to try to minimize dust and dander. Am planning to cut her dosage in half and see if it helps. | F | 8 | 3 months 10 MG 1X day | 6/13/2014 | 1 | Allergies. Dust mites and dust spec | I almost never believe people when they say they have weird side effects. I took this for a year. Thought it was causing me to gain weight(I don't think so really) so I decided to stop taking this. I kept waking up in the middle of the night and eating! That may have been the Zyrtec. Then when I ran out and was literally scrounging around in my car at 1 am since I couldn't sleep without Zyrtec my husband joked. " I think you are addicted to Zyrtec". I barely drink and take no other meds! So I stopped. WOW. The itchiness was so unbearable. I thought I had lice(no) then bedbugs(no). A late night internet search revealed other crazies like me. STILL not a believer I started Zyrtec again when I moved into a dusty house with no AC and windows open... I took it for about a week 5-10mg a night. 2 nights ago I stopped. I just washed my sheets because I was convinced AGAIN I had lice. I have welts on my back this time. I itch ALL over and feel like there are bugs crawling all over me at night! I am so mad!!!! | F | 43 | 1 years 10mg | 6/9/2014 | 1 | Dust mite allergy/allergic rhinitus | The allergy doctor prescribed Zyrtec for my 4 yr old son to help alleviate the symptoms leading to his wheezing cough/respiratory conditions. Pretty soon I noticed that our normally easy-going, sweet boy turned aggressive, and completely over-reacted to things which frustrated him. His heart seemed to be racing faster than normal also. I realised this started the first day he was on Zyrtec. | This one has been tipped down the sink! I'll be looking for more natural alternatives. Should have known better than to trust a pharmaceutical drug! | M | 4 | 5 days 2.5mls 1X day | 6/7/2014 | 1 | Seasonal allergies | Anxiety, racing thoughts, head pressure, inability to focus, quickened heart rate. Originally I thought it was my morning coffee that gave me these symptoms, but I've drank two cups every morning for many years. I found that I had an extremely hard time studying school material, retaining information and just feeling at ease. I noticed I would feel better in the late evening which makes sense as the drug would be in my blood to a lesser degree. I take no other medications and have never experienced these effects on other allergy mess. I'll take my mild allergy symptoms any day. Never again will I take Zyrtec! | M | 25 | 2 days 10mg | 6/6/2014 | 1 | animal allergies | chronic fatigue, weakness, confusion, anxiety, depression, horrible withdrawal | I work with animals and became sensitized to them. Upon recommendation by the veterinarian with whom I work, I started taking Zyrtec. After 2 days, I was so tired and weak, I could barely move. I couldn't remember what day it was, felt anxious one minute and severely depressed the next. I continued taking it thinking/hoping the side effects were temporary. After 2 weeks of hell, I stopped taking it, and now I am experiencing painful, all-over itching so badly, that it is nearly driving me crazy. I will get through this. What I can't understand is why this medication is OTC, let alone why it was ever prescribed for human consumption. | F | 53 | 14 days 10 mg 1X day | 5/24/2014 | 1 | Sinus problem | Chills, dizzy, tired, evil | DON'T TAKE | M | 65 | 2 days 20 1X day | 5/22/2014 | 1 | Seasonal allergys | Irregular heart beat. Either PAC's or PVC's. Terrible shaking. Vision problems. I quit taking it and the shakes and irregular heart problems went way. My vision has not returned to normal and it's been a few months | Are there any class action suits againt the makers of this terrible drug. I'm an RN and I can't believe Zyrtec is allowed to stay on the market | M | 56 | 10 days 1X day | 5/21/2014 | 1 | Allergies | Thought this medicine was a God send until the second day when I could no longer urinate beyond a dribble at a time. That scared me because I drink up to 11 glasses of water a day. My urethra and bladder have been hurting since I began taking this.I decided to look up the side effects and lo and behold painful urination is a side effect. I took my last pill the night before and today I am up and walking around, I had previously lain in bed for 5 days in agony after the doctor told me there's nothing wrong. I'd also like to know if these urinary problems are reversible? Be VERY careful with this medicine. | F | 36 | 8 days 10mg | 5/15/2014 | 1 | Allergies | Thought I was just getting older but went off this drug and found it had caused extreme insomnia where I needed medication. Also made me angry for no reason. Very bad drug! Never taking again! Should be removed from market as the side effects are not work the reduced sneezes and other allergy issues. | F | 44 | 5 years 10mg | 4/21/2014 | 2 | It was a GENERIC BRAND | Terrible nightmares. And non- generic Zyrtec does not cause these night terrors! | F | 39 | 5 days 10 | 4/20/2014 | 1 | seasonal allergies | Children's dye, sugar and alcohol free bubblegum flavored liquid: within 30 minutes of giving this to my 3 1/2 year old, she became angry, unreasonable and violent. She didn't sleep well for several days and the behavior changes lasted 2 days after just one dose. Oh, and several hours after taking it (just 1/2 tsp one time), she was digging on her leg with a sharpish stick, like she was trying to cut herself, but didn't have access to anything sharp enough. I will never use this medication again! | F | 3 | 1 days 1/2 tsp ch 1X day | 4/19/2014 | 1 | seasonal allergies | Children's dye, sugar and alcohol free bubblegum flavored liquid: within 30 minutes of giving this to my 3 1/2 year old, she became angry, unreasonable and violent. She didn't sleep well for several days and the behavior changes lasted 2 days after just one dose. Oh, and several hours after taking it (just 1/2 tsp one time), she was digging on her leg with a sharpish stick, like she was trying to cut herself, but didn't have access to anything sharp enough. I will never use this medication again! | F | 3 | 1 days 1/2 tsp ch 1X day | 4/19/2014 | 1 | Sneeze attacks | I took Zyrtec last Oct because I was having sneeze attacks often because of allergies I developed when I moved to LA. I took it for 6 days, I noticed on the 3rd night when I laid down to go to bed I could NOT breathe out of my nose so I just assumed I was getting a cold but by the 6th night I was in panic mode and could NOT breathe at all!!!! ...I called my sister and conf in a 24 hour pharmacists and he told me what to do to get me to breathe again and to discontinue with Zyrtec so of course I stopped!! HOWEVER Zyrtec left very strange and seems to be permanent terrible side effects!!!!! First of all I ended up with a chronic stuffed up nose because the Zyrtec dried up my inner nasel tissues so bad, then because of my nose being stuffed up from Zyrtec it caused me to go see a doctor which prescribed nasonex to try to undo what the Zyrtec had caused, this helped a little, my nose seems to always be half or all stuffed ever since I took that Zyrtec for 6 days and I can NEVER breathe out if my nose now when I sleep since I took the Zyrtec. I cannot believe I am the only person that this medicine has done this too, there's no way, if it did this to me then it has to have dried out and stuffed up other peoples noses too!!!! ...If I knew Zyrtec was going to cause me to have this stuffed up nose problem I would have never have taken it!!!!! | F | 43 | 6 days | 4/17/2014 | 2 | Allery-related sinusitis | Depression, irritability, negative and hateful thoughts, mood swings, fatigue, difficulty getting out of bed | This medicine helped my sinusitis immediately, but I was a depressed basket case while taking it. I was pissed off at everyone all the time and couldn't find a positive thought in my brain... very negative, mean, and depressed. I felt as if there were a pane of glass between the world and me... just couldn't connect. I also lost my libido -- absolutely no interest in sex. I also felt extremely exhausted for about two hours each morning, even after sleeping 9-10 hours (I was only taking 5 mg once per day, right before bed), and would just lie in bed not wanting to face the world. Once I stopped the drug, I felt normal within 24 hours. | F | 44 | 2.5 weeks 5 mg 1X day | 3/28/2014 | 1 | Allergies | I will never take Zyrtec again! Talk about experiencing every crazy emotion you could possibly ever have in just one dose! My allergies have been very bad this season with intense itchy face and eyes, sneezing, couching, congestion, basically what everyone goes thru with Allergies. I dont like taking anykind of medicine at all and will avoid if possible, but I thought I was going to end up ripping my face and eyes out and needed some kind or relief a.s.a.p. Last nite I popped a zyrtec before bed, (Husbands allergy pills) within two hours I awoke right out of sleep and started to feel disoriented like I didnt know if I was really where I was. I then started to feel agitated,angry, upset, fidgety all for no reason. Here I am laying in bed its midnight, Im now wide awake with insomnia and Im feeling like I want to wake my husband up and start yelling at him. I get up and splash my face with cold water, now Im feeling scared and shaky for no reason. I try to lay back down close my eyes and convince myself everything will be okay, Im just overreacting. Out of no where my heart starts beating 240 and Im now convinced that there must be ephedrine in this zyrtec I just took. Im even convinced my Husband knew this zyrtec made you feel this way and let me take it anyway. I get up start pacing and almost thought of going to the Er in case I was having an allergic reaction. I had to try to lay back down cause my heart was beating so fast I thought I was going to pass out if I didnt tr | F | 39 | 1 days 10 mg | 3/9/2014 | 1 | Seasonal Allergies | Very vivid nightmares that would lead me to getting out of bed in a semi-conscious state. I also suffered from anxiety and paranoia. It took me so long to figure out that it was the Zyrtec D because I attributed the psychological stress to the stress of being a first-time father; I had started taking Zyrtec D about two months before my son was born. I am no longer suffering from the nasty side-effects since I stopped taking it about a month ago. | It helped a lot with the seasonal allergies, but not worth the side effects! | M | 34 | 1.5 years 5mg/120mg 2X day | 3/7/2014 | 1 | Allergic Rhinitis | Deep depression, exhaustion, aching and tired limbs, suicidal thoughts. | I started taking this drug to counter the effects of allergic rhinitis. I went from happy go lucky to wanting to sit in the chair and cry all day. When suicidal thoughts started to happen, I looked at what had changed and pinpointed Zyrtec as I noticed that at the end of the 24 hour period when the drug was wearing off, I started to feel better. These tablets have gone out with the rubbish, I feel a different person, the aches and pains have gone and I have my head back. I believe this is a very dangerous drug and should not be sold over the counter. I count myself lucky to not have had the other dreadful symptoms being reported on this webpage. | F | 64 | 2 days 10mg 1X day | 3/3/2014 |
