| 3 | hayfever type symptoms | Drowsiness.Could possibly be dependency forming.Dry mouth.Dehydrated. | Im usually a light sleeper but with zyrtec I sleep very deeply.More like a tranquilizer than an antihistamine although I do find it to be helpful if taken at the first sign of symptoms appearing.If my attack becomes full blown before I take it,it does nothing.Im concerned about becoming too dependant on antihistamines because Ive noticed the more I take them the more frequent are my attacks when Im not using them thus I keep taking thus creating a vicious cycle. | M | 35 | 1 years | 6/19/2003 | 3 | Allergies | No side effects while on drug. Terrible after-effects. If I'm one hour late (over 24 hours) taking the pill I get severe itching/burning over entire body. I've tried to stop taking it and have had these symptoms continuous for a number of days now. Based on what I've read, it may be many more days until I'm over it. Complete misery. | Best drug I've found for relieving allergy symptoms. Too bad you can't stop taking it without major suffering. | M | 35 | 6 months | 10/9/2007 | 3 | F | 35 | 1X day | 8/25/2010 | 3 | Seasonal allergies | I took the one pill once a day right before I went to bed, and it definitely relieved all my symptoms and made me feel great. HOWEVER, I noticed that--even though it had been 12 hours or more since taking the pill--I became VERY tired in the afternoon and evening. Like so tired I fell asleep! This is unlike me. | I believe this pill also gave me strange dreams, like even stranger than the ones I normally have. | F | 35 | 5 days 1X day | 4/12/2010 | 3 | Seasonal Allergies, Ragweed, Polen | Depression, Mood Swings. | Zyrtec handled my allergy symptoms pretty well. Unfortunately I was as crazy as a loon while taking it. | M | 35 | 20 days 10 MG 1X day | 6/5/2013 | 2 | Sinusitis | Helped a bit with my congestion but VERY tired and low on energy. | F | 35 | 3 days 10 | 12/28/2011 | 2 | nasal allergies year round | I had noticed my mood change drastically. I felt like I was PMSing all month long. EVERYTHING got to me. I was in a rage over any little thing. I am normally not like this at all! I tested to see if it was the zyrtec (stopped, symptom went away, started again, symptoms started, and so on). Went back to Claritin and am fine...for now. The same symptom was with my 4 year old. His pediatritian prescribed it for him and I trusted it was ok. Immediately had to stop. My son changed overnight! | should mention this side effect in their product labeling | F | 35 | 3 months | 4/16/2007 | 2 | allergies | I felt tired and had a headache | F | 35 | 4 days | 3/14/2003 | 2 | allergies | mood swings, nightmares, not focus, sleeping problems. I am getting off!!!! | stay away from this drug!!! | M | 35 | 4 days | 9/2/2008 | 2 | seasonal allergies | irritability,"spaciness", lowered social interaction. | my 7 year old daughter experiences seasonal allergies and i gave her this based on rave reviews from friends. since beginning it 4 days ago she has dark circles under her eyes, is spacey and doesn't respond, and is irritable. i am weary of stopping though, because these are also common symptoms of severe ALLERGIES IN CHILDREN. so...? | M | 35 | | 8/18/2009 | 1 | Seasonal Allergies | Agressive behavior, rage, sadness, sleeplessness, confusion. | My pediatrician recommended children's Zyrtec for my 3.5 year old daughter to relieve her allergy symptoms. After taking it steadily and then on and off for 4 months I finally put together that whenever she was on it, she was prone to random major rage events to include kicking, biting, spitting, screaming uncontrolably, whining, sadness, crying at the drop of a hat, Etc...it takes a good 3-4 days for her to withdrawl from 1 2.5 ml. dose during which she can't sleep at night and is a zombie during the day. We are DONE with Zyrtec! | F | 35 | 4 months | 8/11/2009 | 1 | My young son- allergies | Our little boy had extremely negative and agressive behavior. He had uncontrollable temper tantrums at home and in public. He also displayed seemingly depressive behavior. This is just to name a few of the side effects he experienced while taking zyrtec. | Our son began taking zyrtec on a daily basis at 15 months old. It was suggested to us by our pediatrician to assist in our ongoing battle with ear infections and allergies. Initially, we contributed his behaviors to his age and "being a boy" although our first child, also a boy, had never experienced quite these same things. As he got older, we saw a significant increase in his physical agression as well as his extreme temper tantrums. His behavior would turn on a dime and was almost impossible to anticipate. As his primary caregiver during the day, I was beginning to feel like I was losing my mind. By the time my husband came home at night, I was often in tears. Finally, on a whim, I googled zyrtec/negative behaviors...I found a world of parents experiencing the same things as us. At this point, my little boy had been on the medication for over a year and a half. I felt like we had never seen his real personality. After that day, we never gave him Zyrtec again, EVER. His behavior,literally, changed overnight. He is now 4-1/2 and has never ever behaved again as he did while on that drug. Although not all children will react in such a negative way, for us, it was truly a nightmare. When we look back on that time, both my husband and I feel so sad about the fact that we were constantly giving him consequences for behavior that was truly out of his control. | F | 35 | 2 years | 12/29/2009 | 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 | 3/18/2017 | 1 | Allergies | I became very distant and unhappy. I was delirious. I love singing but I am an Administrative Assistant. I found myself calling a blues club in Philadelphia to see about working there as a singer. Also, I had a desire to audition for American Idol. I know this sounds funny and crazy but this pill made me do things I would not normally do. I found myself fantasizing about being famous. My inner most desires were trying to be fulfilled and I was unhappy about my lot in life. I am a positive, happy person and everyone noticed my sadness and glazed over looks. I was not mentally present in the room even though I was there physically. Out of body feeling. Weird. | I would rather take Claratin-D. | F | 35 | 3 days | 9/17/2008 | 1 | Seasonal allergies | Tiredness, grogginess, depression, anger, frustration, suicidal thoughts | Avoid if prone to depression or mood swings | F | 35 | 3 days | 9/2/2008 | 1 | cholestasis of pregnancy | extreme grumpiness and anger, tiredness, confusion | I took one tablet for the first time last night and will NEVER take another. I have not felt this disgusting for years. I am feeling extremely angry and disgusting, as if I have a massive hangover and very jumpy. It should not be on the market | F | 35 | 1 days | 4/21/2009 | 1 | "Possible" Allergies in my 3yo | Mood Swings, Defiance, Agression, Violent Behavior and Thoughts | My son has been taking Zyrtec for 3 days and has turned into an absolute demon--I am not even 100% certain why the Dr. prescribed it but I am tossing it. He is totally out of control and moody. Never again, I will always check this site before filling a prescription. | F | 35 | 3 days | 12/26/2008 | 1 | Allergies, Chronic Sinusitus | dazed feeling, derpression, anxiety, weird thoughts, irritable | unfortunatley Zyrtec really worked pretty well on my allergies and sinus problems, but I'm almost positive they are the culprit of my dazed dizzy anxious state that I get in. The worst is I think they are causing me to awake from sleep gasping for breath!!! I think this is a seriously bad drug to take....use caution. | M | 35 | 3 months | 5/6/2008 | 1 | Allergic reaction to an antibiotic | Extreme anxiety, accelerated heart rate, depression, extreme dreams. | Took Zyrtec to help with an allergic reaction to an anti biotic. Took days to realize that Zyrtec is the cause to my listed symptoms. I've never suffered from anxiety or panic attacks until a few days into taking, day 6 turned into terrible dreams and borderline hallucinations. When I wake up I cannot tell if I'm still dreaming or awake. I will never take again. | M | 35 | 7 days 1X day | 5/16/2021 | 1 | Sinus allergy | It is great for allergies but causes terrible depression,, right now I am crying,, whenever I take zyrtec I feel so down and stupid and I cry | F | 35 | 2 days 1X day | 5/26/2022 |
