 1  Seasonal Allergies My daughter is 3 and has been having uncontrollable rages and tantrums. She is typically very sensitive so the occasional tantrum is typical but these tantrums last all day and are frightening; with her throwing herself off furniture and onto the floor, screaming and scratching at herself and others. She is inconsolable. She will never take this medicine again. F 3 5 days

 3  Running Nose, Sneezing and Watery E I am not sure but it might be related to Zyrtec with vision changes, giving me a crazy looks; unable to look people in the eyes. Also, I noticed my feet ankles being swollen and I do not consuming that much of salt diets. I thought Zyrtec, and other Allergy-related drugs are not supposed to cause such harm as others have commented on its use. According to my Ear and Throat doctor, Zyrtec and other related Allergy Meds and Sprays should be safe since they do not go through one's bloodstream but showed otherwise. With all these negatives being noted about Zyrtec and other Allergy drugs, I as a person with allergies do not know else what to take. If an adult person is experiencing such severe problems, what about children, babies (toddlers) for that matter, who are unable to express their feelings, is very devastating; Zyrtec and others similar to it need monitoring and regulating by the Food Drug Administration or any other departments responsible to oversee drugs usage.

 1  Allergies! Given this by doctor Heart racing, anxious, feeling uncoordinated, dizzy, feeling "drunk" while walking, shaking, dry mouth. I don't have enough words for what this medication has done to me. I was standing in church today looking like a drunk (BTW I don't drink). My movement was so slow. I had to hold on to walls the last five days. My coworkers didn't want me driving and I haven't driven in two days. And today, to top it off, I thought my heart was going to race out of my chest. I would have never thought an allergy medicine could cause such issues. I haven't played with my son because I can't do it. I finally spent the whole day doing research. Why is this medicine an OTC when its so dangerous? I thought I was losing it! There are so many people saying what it does wrong to them. I still don't really have the coordination to type this. My mind won't work! But I will never ever take this medication again. F 36 5 days

 1  allergies sleep paralysis, feeling very "out of it", anxious, lack of energy My allergies were really acting up and my typical medicine wasn't doing much so my doctor recommended Zyrtec. After taking it for a few days, I experienced sleep paralysis for the first time in my life. Since I had just started taking this medicine, I decided to look up other side effects of zyrtec. I couldn't believe that an allergy medication could cause something as horrible as sleep paralysis, but apparently I'm not the only one who experienced it. Also, I noticed that i was really out of it the few days I was taking this but I didn't think anything of it until recently. Also I was a lot more anxious than usual. And I was tired all the time too. I don't understand how this medicine is still allowed to be sold. F 17 5 days

 1  Nasal drainage Blurred vision, rage, anxiety, lack of concentration, dry mouth This stuff is awful. I had no idea what was causing me to suddenly have such anger and blurry vision. I started to think of what I had changed in my diet or otherwise. It was then that I remembered I had started Zyrtec, at my doctors recommendation. I won't be taking it again and hope this all goes away quickly! F 48 3 weeks

 1  child's chronic allergies My son, experiencing restlessness, involuntary jerking of extremities, palpitations, wheezing, numbness of hands, stomach achee, overall feeling of illness. I'm so hopeful these side effect disappear because they are worse then what zyrtec is supposed to do for my child. Everything put into you're body is a risk, but 2 weeks later I'm not interested in this medication and strongly advise you to think twice before using. Nothing scarier then your child gasping for air. M 7 2 weeks

 1  Seasonal allergies My son was put on Zyrtec from his pediatrician. The first week he was good then the next week my son started breathing deep and said his heart was beeping fast took him to the ER twice his oxygen was good but they said keep a eye on him . He did not sleep well at night and took him forever to get to sleep. I took him off the Zyrtec to see what would happen and all of his symptoms went away. Then 2 weeks later I tried it again because his allergys were acting up . Guess what same thing deep breathes and his heart racing again. I will never give him Zyrtec again. Have to find something different! 4 1 months

 1  Seasonal allergies Depression, rage, complete personality change. To be clear, I'm generally a very well adjusted person who has never suffered from psychiatric issues. It took me a few weeks to understand that my sudden personality change stemmed from this new allergy medication. It did relieve my allergies, and the doctor said it was best to take it consistently, so I was. While on this, I seriously thought about hurting myself, I thought about hurting my husband, and I had completely unreasonable thoughts and reactions to people. I have never been in such a dark place in my head. Soon after I stopped taking Zyrtec, I was back to normal. This is scary stuff, and I can't believe it's on the market. Allergies are nasty, but I am not willing to sacrafice my sanity to alleviate them. F 34 3 weeks

 2  Seasonal allergies Sleeplessness, vivid, frightening dreams, anxiety, and recently vertigo when sitting and looking down mostly. Also have had some ringing in ears and a clicking sound with some ear pressure. I have had a number of symptoms for some time that I didn't think to attribute to Zyrtec as it is now OTC and my physician recommended it for seasonal allergies and sinus pressure. After reading a lot of these other posts I'm realizing it may be the Zyrtec causing them, especially the vertigo I've recently experienced. I am going to try a gradual withdrawal to see what subsides and what ensues. F 58 365 days

 1  allergies I have year round allergies. My Dr. prescribed over the counter Zyrtec 10 mlgs 1 a day for year round allergies. I'm not one to take medication so I took it only when I felt I needed it. I took most of medication during the day and noticed with I took the first dose it made me feel anxious and my heart started to race a bit.. Can't take any decongestants because it makes my heart race. So I thought this was okay to take. Took it on another occasion at around 6 in the evening. When I went to bed around 10 and laid down to go to sleep I felt very nervous and anxious. Took my heart rated and it felt as though I was out jogging, About 4 in the morning my heart rate finally slowed to normal. Took the bottle to my Dr. and told him to put it on my allergy list. My do not take list. F 3 weeks

 1  For an allergy brought on by insect I began using this OTC drug for urticaria but it was mild. After 3 months I felt worn out, weak muscles and having a sense of confusion, tight pressure in my head and then the vertigo hit me two weeks ago today. I have stopped taking Zyrtec and never want to use it again. Stopping Zyrtec is awful. The itching is so intense and a new one - my lips have been swollen all day. This is day 3 of withdrawal. On day 2 I noticed that I could see properly again - had not realised my eyes had been blurred. And my concentration has improved I was becoming confused. However the vertigo still comes intermittently especially if I lie down but triggers vary - a nightmare. I hope it isnt going to be permanent and that my lips will go back to normal. If anyone has had vertigo as a side affect of Zyrtec Id be interested to know how that's gone and if youve recovered. Has anyone had any permanent damage? As I burn and itch tonight am thinking of everyone else going tgrough this Thank goodness for your support - I wish you all the best. F 65 3 months

 1  Allergies Had more trouble breathing after taking medicine. Symptoms after taking this black market evil drug during the day. We're extreme fatigue,more trouble breathing and almost like being impaired not being able to concentrate normally. I was itching very badly and trouble breathing so I figured Allergies during the Spring right????. Wrong my friend noticed they my diet consisted of to much Wheat. Like breads,pastas,soft shell tortillas. Etc wheat is in so Many things I didn't realize. So I stopped eating anything with Wheat in it for 3 days. My inching stopped never to return and my Allergies all went away, I feel so much better in every way now that my diet doesn't include Wheat. Sad part is I went to the Doctor for these Allergies over a year and a half. Giving me different Ned's to try and 4 different prescription creams and Never once did he mention about my diet or WHEAT. Lmfao. STAY AWAY FROM WHEAT BAD BAD STUFF NOW A DAYS. JUST READ THE PROBLEMS IT CAUSES. M 4 days

 1  Seasonal allergies and eczema Anger, moodiness, nightmares, hallucinations, confusion, drowsiness, loss of appetite, decreased urine output, rash, flushing, and the worst was stuttering and apraxia of speech. He went from advanced talking to not able to form words or speak with out severe stutter. This medicine is horrible. Do not give it to your kids. Caused many symptoms with my son including speech problems and stuttering. After one week of being off this medicine his behavior was normal and his stutter was gone!! I will never use this medicine again. This is too strong for small children's brains. The worst part is no one ever warned me about these possible severe side effects. He was a completely different child on this medicine. So glad I did some research and figured out what caused his sudden change. M 2.5 3 months
