| RATING | REASON | SIDE EFFECTS FOR ZYRTEC | COMMENTS | SEX | AGE | DURATION/ DOSAGE | DATE ADDED |
| 1 | allergies and hives | Weight gain, depression..blues | F | 53 | 10 years | 2/26/2014 | 1 | Seasonal allergies | Horrible nightmares. Anxiety. Panic. Affected brain/thoughts. Colic/constipation/diarrhea - yes, turned GI upside down. Vision got worse, haven't recovered. | M | 53 | 2 weeks 10 mg 1X day | 7/1/2014 | 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 | Head cold | Tired and had vicious ghastly dreams that left me extremely frightened for several minutes after I awakened. Sad feelings during the day and even cried for no reason. Very curt with others even angered easily! Been Zyrtec free for 2 days and feeling Better. No more nightmares! This is a mind altering medicine. Will never take this medicine again! | M | 53 | 2 days 5mg | 12/18/2013 | 1 | hayfever | I took only 5 doses in March 2009, it cleared up my runny nose and I could breath again. BUT I lost my complete sense of smell! I can't smell at all and I use to have a very good sense of smell. Now days I might get a small whiff of something but it's very rare. | I had never taken this medicine before, this was my first and last time. I want my sense of smell back so bad. | F | 53 | 5 days | 8/23/2009 | 1 | Allegeric to pollen | Extreme sleepiness about 24 hours, the same effect after reducing dosage by half. | I prefer allegra and telfexo they don't make me sleepy at all. | F | 53 | 2 days 30mg 1X day | 3/17/2022 | 1 | Household allergies | I had been taking generic Zyrtec for a long time for cat and dust mite allergies... it stopped working, so I thought I would give the name brand a shot- THAT was a mistake. It brought on, completely out of the blue, unbridled anxiety, weight gain and a lack of motivation. I thought, perhaps, my hormones were out of whack (I am on BHRT), so had them tested and there was nothing wrong- everything was balanced, so I was baffled and then realized that I had started the Zyrtec a couple of weeks ago. I didn't take it yesterday and, already, today I am feeling MUCH better. I don't recommend to anyone to ever take this crap. No wonder we live in a society with mass depression and anxiety everywhere. | F | 53 | 16 days 1X day | 7/13/2023 | 1 | Seasonal allergies | Lost in bad thoughts, rage, forgetfulness, anxiety, severe mood swings, weight gain, excessive comfort eating, and depression | Controls my symptoms, but at a severe mental stability and health risk. | M | 53 | 15 years 1 every 12 | 5/28/2019 | 1 | Allergies | Extreme malaise, tired, brain fog, wanting to fall asleep, anxious, all over tired | I feel like I'm drugged. Legs and arms tied, brain tired, not happy at all feel like I need to sleep. Made my anxiety worse because of how it makes me feel. | F | 53 | 3 days 20mg 1X day | 2/15/2021 | 4 | Allergy | F | 54 | 2 years 20 1X day | 11/26/2019 | 4 | allergy | M | 54 | 2 years 1X AN | 4/22/2019 | 4 | allergy | None | F | 54 | 2 years 20 mg 1X AN | 4/22/2019 | 3 | Allergies | Severe tiredness, emotionally numb, no motivation, severely depressed. Helped with allergies but cannot stand how I am feeling emotionally. | F | 54 | 17 days 10mg | 4/19/2020 | 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 | 1X AN | 3/22/2016 | 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. | F | 54 | 1X AN | 3/10/2016 | 3 | allergic rhinitis / stuffy nose | some slight swelling on my ankles, noticed some weight gain by wanting to eat more. | I usually take this medication at night before going to bed, and I have to admit the medication does what it is suppose to do with allergy symptoms. I am allergic to dust, dustmites, pollen, grasses, mold, and my symptoms were very severe this spring, so my ent started me back on immunotheraphy. | F | 54 | 21 days | 6/19/2007 | 3 | Cronic year round allergies | I have been on this drug for years to help treat my cronic allergies for mold and just about everything else. Over the last 2 years I have been having issues with heart palpitations, new sinus sensitivity and daily stomach distress. I have alway been in good health otherwise and take allergy shots for 1+ year as well. I tried the reflux otc drugs for my stomach with minimal improvement. I have been to the doctor about these problems with no answers yet. I now wonder if this may be a growing side effect from my years of zyrtec use. I take 10mg before bed. It works like a sleeping pill for me and I am use to the lower energy level. After reading many of the posts here. I believe it's time to get off this drug for several weeks and see what happens. I will post again with any results of my test. | This drug really does help stop post nasal drip problems better than any of the drugs that I have tried over the years. But it can dry you out to much and cause an accute sinus sensitivity and if compounded with a flonese spray can become what appears as a very painful sinus infection without any real virus involved. Doctors give you antibotics which have no effect. I learned that nitetime room humidity at(50%+) and nasal washes finally stopped this problem. | M | 54 | 10 years | 1/9/2007 | 3 | congestion and headaches | I have been very sleepy, I still got headaches but fewer. I still was congested even though I didn't know how much until I went for a ct scan. It showed me fully congested in all sinuses(all areas gray). I am now on strong antibiotic with saline nasal washes with afrin(5 days of afrin) and 14 days on Augmentum 1000 mg two at am and two at pm. Now I have decided to stay off of zyrtec and I have been itchy all over my body. This happened to me another time I decided to stop for two days I was itchy all over all day long. After restarting I was ok. | I am not sure what happened since I've been on zyrtec for 3 years thinking it was helping me. This itchiness has never been mentioned as a side effect for stopping the zyrtec. Are there many others experiencing this. All I know is that I will never resume with zyrtec again, knowing that I will be itchy if I stop. It's not worth it. I have to find something else??? | F | 54 | 3 days | 6/13/2005 | 2 | seasonal allergies | Tachycardia, palpitations, variable vision, vivid dreams | Although Zyrtec relieved my allergy symptoms, I cannot tolerate the side effects. Thought I was developing heart disease until I started thinking my symptoms might be related to Zyrtec. An online search confirmed my suspicions. | F | 54 | 60 days 1X day | 7/31/2014 | 1 | allergies, headaches | It was prescribed years ago by my ENT Doctor and I said I'd never take it again because it made me very drowsy... I did. I really made a bad mistake. In December 2008, it made me act worse than having had several drinks. My friends stayed away from me. Eventually, I passed out. It made sense if years before it made me drowsy, passing out seems like a logical step. | I dumped the pills. My perspective: DON'T TAKE IT. We're inundated with side-effects from drugs so we think, what the heck, they all have side-effects. BUT THIS IS WORSE THAN MANY. You can also forget what the FDA approves or doesn't and you know how effective governmental oversight has been for years. People taking the drug know best. | F | 54 | 3 days | 2/25/2009 |
