 1  Allergies (seasonal) Anxiety, irritability, weight gain, dry mouth, fatigue, insomnia, mild depression, mood swings and vivid dreams. Started Zyrtec about 8 weeks ago and noticed about a 8 lb weight gain...some other psychological symptoms. I run 5 miles a day x5 days a week and was surprised at this sudden increase in weight and bloating. Also triggered an increase in hunger. Never experienced psychological issues (mood swings, insomnia, irritability, anxiety, depression) before until I started taking this drug. Although the psychological symptoms are mild, they are still upsetting. These side effects started about 1 week after I started taking it. I have stopped Zyrtec due to not "feeling myself" anymore. Hopefully, these symptoms from the drug will cease very soon so I can return to being happy and healthy. F 42 8 weeks

 1  year round allergies Well i have been dizzy for 3 days now. Went to the hospital because it got so bad. Got diagnosed with severe vertigo. So i got curious as to what was causing it and realized i havent had my zyrtec for 5 days due to a mix up on refills at the dr office. Took some benadryl and vertigo is slowly going away. Who knew? Im going to talk to my doctor about trying something else at my appointment in 2 days Dont know if its good or bad F 28 2 years

 3  Allergies related problems; watery I have already left a comment but want to expand on it a little. If it were not for this site, which I left comments for other allergy-related meds, Zyrtec would have continued to destroy me. Now I am aware that it is possibly it was the one causing the symptoms such as deadening my spirit (disquieting), making my eyes look crazy or have lost my senses, widening my eyelids or sometimes my eyes' shapes becoming smaller, I am deeply grateful and appreciative. Words are indescribable the wonders this site has done for me as I was not sure what was going on with me. Thank you so very much for having this site up for people like myself, especially children, who may not be able to relate or express their feelings of what happening to them. Your site is a blessing !!! I am very grateful and deeply appreciative of this/your site. F 54

 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
