 1  Allergies and post nasal drip Excessive coughing 24 hours a day, insomnia, trouble swallowing, trouble breathing, severe constipation, fast heart rate, dizziness Doctor prescribed Zyrtec for supposed nasal drip. It caused a medium cough that I already had to get 10 times worse. I coughed 24 hours a day on Zyrtec. Nothing seemed to work until we started looking at the side effects of Zyrtec and realized that I should not even have been prescribed this medication with the conditions I already have, Zyrtec just compounded everything to the point where I was feeling worse by the day. It is awful and I immediately stopped it and will not let my doctor tell me I have to take it. Doctors nowadays are so busy they don't even pay attention to what you're telling them. They prescribe things without truly telling you what the side effects might be. Best thing to do is talk to the pharmacist they know more about a medication than a doctor does. M 88 2 weeks

 1  Allergies fluid in ears The med itself worked great for the most part. After a while I began to have issues with fluid in my ears again. I had to stop taking it for an allergy test. O dodnt even know there were withdrawals from allergy medications. I HAVE NEVER ITCHED SO BAD IN MY LIFE. I have had dermatitis that didnt itch this bad. I want to cry. This is day 2 of this. I'm having heart palpitations at night when I normally took the pill. It's also causing the worst smelling gas I have ever had. I had no clue what was going on until a coworker had brought up if it could be me coming off my allery medicine. I said I didnt think so and then googled it and there is SO much info on this. I can not believe they dont warn people of this. I cant believe they recommend this for children. Shame on them!!!! F 38 2 years

 1  ragweed allergy intense mood swings, uncontrollable crying spells, inability to focus, depression and despair, feeling hopeless, suicidal thoughts that came out of nowhere I am appalled that this is sold OTC with the side effects so many people are experiencing. I usually take Allegra but it doesn't cut it for my late-summer ragweed allergy so thought I'd try something stronger. Well I stopped sneezing but just mentally had the week from hell..this totally changed my personality, I do struggle with some anxiety but not depression and honestly can't remember the last time I cried before taking this. I am traumatized that a seemingly “harmless” allergy med can be so destructive. Never taking this again!! F 36 10 days

 1  Allergies Have tried going off of it but intense itching sets in on day 2. Am now slowly weaning myself of it. Also have gained about 10lbs and have changed nothing in my diet/exercise. I am runner--I run 6 miles 4x week. I wish I had been told about the weight gain possibility and how hard it would be to get off the drug. F 52 8 months

 2  Allergies Sadness, lack of motivation, extreme fatigue, excessive sleepiness, moodiness, tired. I took Zyrtec everyday for 4 weeks for Allergies, I previously only took it occasionally. 2 weeks in i started feeling just extremely tired. I suddenly was sleeping 12 hours a day and even that wasn't enough sleep. I was skipping class and work because i literally couldn't get up. I slept from 9pm to 1pm in the afternoon and felt moody and irritable. I finally realized it may be the zyrtec and stopped taking it, and i was better and felt normal after just a couple days. never again. M 19 4 weeks

 1  Allergies Extreme dizziness, anxiety, panic, couldn't absorb information, vision problems, dry mouth I am shocked how terrible I felt on this medication. It took a few weeks for me to notice how badly I felt so I didn't connect the dots. Started feeling dizzy and incredibly anxious. Couldn't absorb information or speak clearly. Felt like my thoughts were jumbled. Couldn't see clearly. Thought I was losing my mind. Felt extremely depressed, lots of crying and anxiety episodes. Thank you so much for this website and your reviews. F 38 40 days

 1  Allergy Swallowing and breathing difficulties. Caused UTI. Dehydration. Extreme weight loss. Lips swollen. Face swollen. Horrible drug. Caused hospitalisations. Nursing home. In my opinion, this drug should not be on the market. Should not have been approved. Very dangerous. F 66 2 years

 1  Allergies EXTREME ITCHING WHILE TRYING TO QUIT. I cannot get off zyrtec due to the extreme itching after not taking it for 2 days. I will have to slowly wean off and I am so nervous for this journey. I imagine if I were to quit Zyrtec I will feel much better than I have in years. I have read countless reviews about the brain fog, forgetfulness, anxiety, and emotional toll it takes on people. I am wondering if my anxiety and bursts of emotion are coming from this and maybe I can even get off my anxiety medication. I am excited to kick this drug, but it is going to be so hard slowly weaning off to not experience the itching. I highly recommend NO ONE EVER TAKE THIS. F 30 15 years

 1  Allergies asthma I started taking it in 1st grade due to my severe allergies and it seemed to work, so my mom would give it to me every day and if I missed a dose I would be sick. I developed squinting of my eyes, which led to now having full blown tics both vocal and motor tics, I can't control them and never associated them to zyrtec until my friends mom told me about him having tics due to zyrtec as well and they started the same way! My mom stopped giving me zyrtec way before we realized this and put me on xyal now I'm scared to death to take anything but I'm scarred for life with these TICS BECAUSE OF THIS MEDICATION! AND THEY KNOW THIS AND STILL SELL AND MORE AND MORE CHILDREN AND ADULTS CONTINUE TO HAVE TICS WHICH HAVE NO CURE ! F 18 7 years

 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

 1  Sinus allergies Mood swings, weight gain, dry mouth, inability to drink plain water (disgusted by water!), Dragging my feet and feeling EXHAUSTED ALL THE TIME!!! Decreased libido, anxiety. I started taking this pill on and off for several months at a time and stopping for a few days at a time and going back at it since Jan 2018. I was not suspecting this pill was the root of all of my problems. I gained 40 lbs since 2018 while working out, dieting and I was not able to drop more than 5 lbs and then gaining all back. I thought the problem was my age! When I decided to get off of it, experienced horrible itching all over my body similar to when you drink pre-work out that contains beta-alanine, is not in your skin, is somewhere a little bit more deep inside your skin. Also felt like throwing up, could not fall asleep, my mid section started to shrink within 3 days after stopping! I do not feel like snacking or bloated. I know I'm going to keep pushing through getting off of zyrtec, It is my 6th day, so far CBD oil before going to bed and shower a few times a day with cold water has helped a lot with itchiness.

 1  Seasonal allergies Irritable, moody, night terrors. My kid never had issues sleeping and was generally a very happy child. The only thing I changed was I switched from Claratin to Zyrtec and he changed. Moods and all. I did not connect that to Zyrtec till I noticed that he began having night terrors. I took him off 24 hours ago. Let's hope things get better. M 5 4 days

 2  Allergies My 7 year old took Zyrtec for a year for seasonal allergies. It seemed to work wonders! His allergy symptoms disappeared. Not long after starting the medication, he complained daily of horrible abdominal pain. We saw countless doctors, looking for answers. Blood test, after blood test, X-rays, CT scans, upper and lower scopes, food sensitivity tests, we even saw an urologist! None of the above gave us any answers! We were left with a 7 year old with what they called "unexplained chronic abdominal pain"! I felt so helpless! We decided to stop the Zyrtec temporarily, his belly pain completely disappeared! I was shocked! I came across this site and could not believe how many others have experienced the same symptoms! This drug has caused so much you left for my family, something needs to be done! In the year he was on the medication he also experienced itchy skin, headaches and sore throat! M 7 1 years

 3  Springtime allergies I got extremely depressed after taking the drug for a few days in a row. It works very well as far as curbing the symptoms of pollen allergies. I liked it because it didn't knock me out like other allergy medications. However, I'll only take it again if I'm really suffering, and I'll certainly alert others of my mood swings. M 60 3 days

 1  Allergies Helped with allergies but seems to have caused an extreme emotional crisis on day three. I lost all comprehension of what was real, to the point where I wasn't really sure of anything. The anxiety-enhancing qualities of the medication are INSANE & I've no desire to take this again. M 34 4 days
