| 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 10 mgs 1X day | 12/5/2015 | 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 | 12/4/2015 | 1 | For an allergy brought on by insect | I began using this OTC drug for urticaria but it was mild.

Nothing helped to soothe them. Stopped taking med 2 days ago. and now lips are peeling. Hope this clears up soon. | F | 48 | 14 days 10 mg 1X day | 12/1/2015 | 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 30mg 1X AN | 11/18/2015 | 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 1/2 tsp | 10/26/2015 | 1 | Uncontrollable allergies | Headache, dry mouth, dry eyes, fatigue, restlessness, sleep disturbance, difficulty breathing upon exertion (even walking up steps), rapid heart beat during cardio exercise | I took this medication after my loratadine did not work for my fall allergies. They have been bad this year and I needed to look for something new after not being able to control a persistent hacking cough for over three weeks. Right away I noticed this medication made me tired. Not unexpected and for the relief I needed I could deal with that. Then I noticed my mouth and eyes became extremely dry. Since it helped to dry up some of my congestion and seemed to offer me some relief, I thought "I can deal". I am a very active person and exercise (cardio, weights, biking and running) regularly and I noticed that the mouth dryness became pretty intense during exercise, no matter how much water I drank (and I usually have 64 ounces of water or more pre exercise). It felt like I had a dry sponge in my mouth. On top of that, when I was active I noticed I needed to take frequent breaks to catch my breath and to help the feeling that my heart was going to thump out of my chest subside. I felt winded even walking up stairs. No thank you to all of that! Plus, I quickly noticed that when I tried to sleep my legs felt restless and my sleep quality was poor. All of these things are very unlike me. I went off the Zyrtec-D three days ago and onto a natural allergy relief product and already feel a world better! I know my body well and just over a week of Zyertec-D was enough for my to know this OTC medication has serious side effects that may not be desirable. | F | 41 | 1 weeks 5mg/ 120 m 2X day | 10/23/2015 | 1 | Seasonal allergies | Frequent anger and murderous rage from a gentle, loving kid. | I attributed my son's marked personality change to problems at school. It took me a while to make the connection to Zyrtec. He was back to normal as soon he stopped taking it. | M | 6 | 2 months 5 mg 1X day | 10/21/2015 | 1 | Seasonal allergies | Frequent anger and murderous rage from a gentle, loving kid. | I attributed my son's marked personality change to problems at school. It took weeks for me to make the connection to Zyrtec. He was back to normal as soon he stopped taking it. | M | 6 | 1 years 5 mg 1X day | 10/20/2015 | 1 | Allergies (runny nose, coughing) | Extreme difficultly breathing and excess congestion. Also, jitters and labored breathing after the main incident, as well as a headache. | I woke up this morning with chest congestion, which is normal, and had a runny nose, neither of which wanted to clear by an early morning doctors visit. I was a first time patient and didn't want to go in and have everyone thinking I was seriously ill. I was also very tired, which made things seem worse. So, I took HALF of one of my mom's Zyrtec tabs. By the time we got home (roughly two hours later) my throat was tight and it was impossible to take a deep breath on my own. I would have been in the ER if not for my respirator that I have to use at night anyway. After a couple of hours I was able to breathe on my own again, but I still have tightness in my chest and more congestion than before I took this evil pill. I also became extremely cold, and the doctor did say my blood pressure was low. Now, several hours later, I am experiencing the "common" side effects: jitters, labored breathing and a headache. I will definitely be going back to my trusty Sudafed Non-Drying. | F | 41 | 1 days 10mg | 10/20/2015 | 1 | Ragweed pollen allergies | It feels like my brain is still asleep the next day. Tiredness, Lethargy, Brain fog, Sadness | The morning after I took prescription Zyrtec I woke up extremely congested and irritated as if I hadn't taken an allergy pill. Apart from the fact that I still had all the allergy symptoms I had the added bonus of all the negative side effects of this medicine. I sat on my bed all day waiting for the side effects to wear off. I had a date later that evening and worried that I will appear depressed or miserable. This was so frustrating. I won't take this medication again 😔 | F | 55 | 1 days 20 mg | 10/12/2015 | 1 | Allergies (?) Indoor & Outdoor | Irritability, increased appetite/weight gain, lethargy, increased sleep, flat effect, brain fog, unexplained rashes, vision issues.....still figuring this out.... | This drug should be only used in emergency & real allergy testing done immediately to rule out causes and focus on the real allergy, dairy, gluten or fake additives in our food, made worse by environmental triggers (aka indoor & outdoor allergies). Experienced extreme withdrawal symptoms while going off for 5-7 days to get allergy tested. Will never take again, was diagnosed with food allergies, so no need. Researched other alternatives if seasonal or indoor & outdoor allergies become bothersome. | F | 57 | 9 years 10 mg | 10/8/2015 | 5 | Kimura's & chronic conjunctavitis | extreme somnolence, agitation, dry mouth, mild 'delirium' | Zyrtec is the only treatment ive found for Kimura's disease, a rare inflammatory condition Zyrtec is also very effective in treating my chronic conjunctivitis Zyrtec (cetirizine) is most effective with a healthy metabolic system. If you have metabolic problems it will increase the intensity of side effects such as extreme somnolence, agitation and dry mouth as the drug will stay in your system longer. Using the drug has been very effective over the years. I was originally prescribed this over 10 years ago for chronic red-eye and found it was, when taken consistently for a 1-2 weeks will improve inflammation and will remain effective for a period of upto a month. The problem with taking zyrtec for this amount of time is the side effects become much more noticeable and compound to the point where I have to decide on to continue or stop taking zyrtec for a time. After continual doses over a few days i become agitated, have confused dreams, and lose sleep. The immediate side effect is extreme somnolence that persists for hours or days after the last dose if i havent taken it for a period of time. Yes, zyrtec is a life saver for my conditions but it comes at a cost of effectiveness vs side effects. I am trying to stay healthy to improve the effectivness of zyrtec so I can take less of it and still get the benefits. | M | 30 | 12 years 25 1X W | 10/3/2015 | 3 | Allergies/hay fever | Extreme tiredness, brain fog, very lethargic, extreme frequent urination and bladder irritation!! | It works on the allergies for the most part, but with icky side effects. Never feel right when I take it. Even a 5 mg dose does all that I've listed. What worries me the most is the extreme bladder irritation and frequent urination. Yet it gives me kind of a dry mouth. I've been taking it for over a month. | F | 45 | 1 weeks 10mg | 9/27/2015 | 1 | Allergies | Heart palpitations, extreme anxiety, depression to the point I would burst into tears at random times. | The active ingredient in this drug is cetirizine hydrochloride, and quite frankly it should be banned. I'm a confident social person and I took this drug for a month. During that month I felt like my heart rate was over 100 most of the time. I was depressed and had severe debilitating anxiety. I simply could not function and most mornings couldn't physically leave the house to go to work. When I was at work I would go into the toilet cubicle and be unable to walk out of there. It was frightening being like that. I would cry for no reason despite not being a crier. Normal situations were starting to cause extreme anxiety to the point where I would just want to shut myself away from the world all the time. It took WEEKS for me to get back to normal after taking it, so don't be alarmed if you're not back to your old self in just a few days. This drug gave me the worst month of my life. Please don't take it, especially if you are in any way an anxious person to start with. This drug completely changes your personality while you're on it and makes day to day life very difficult to cope with. It really should be banned. | M | 32 | 1 months 10mg | 9/9/2015 | 1 | for hives | Nausea and dizzy I cant go outside I fant every time I try..can eat cant sleep my nerves system cant stop shaking headache eyes blurry light headed cheats pain shortness of breath vomiting passing out fever and chills | We need to do something about this!! | M | 28 | 1 days 1 pill | 9/3/2015 | 1 | Seasonal allergies | I could not believe when I found this site and read all of the comments. I've been experiencing all of the same symptoms but never contributed them to taking Zyrtec. I've gained a lot of weight, I'm always bloated and gassy, lethargic, depressed and moody. I haven't felt myself in quite some time. | A side note to this for all of the women out there, is that a lot of these symptoms are similar to those of Ovarian Cancer. My mom was recently diagnosed and had many of the symptoms we've experienced taking Zyrtec. So if you are able, please get that checked. It's called the "silent cancer" because it's symptoms are easily dismissed! | F | 38 | 9 months | 9/1/2015 | 4 | Seasonal Hay Fever | Dry nose, nasal crusting, blood in nose, mild drowsiness | This stuff works well on hay fever, maybe a little too well because I can only take half a pill and I'll be good for about 3 days. It does make me a little bit drowsy so I take it at night, sometimes I wake up and feel fine, other times I've felt a bit foggy but it wears off. It also dries up my nose because it's strong, I get a lot of crusting and blood due to the dryness. However these side effects are tolerable and better than having bad hay fever. | M | 27 | 3 months 2X W | 8/28/2015 | 1 | Seasonal allergies | Daily drowsiness, severe funk, increased appetite. | I was so relieved when I came across this site! Just spent an entire weekend in a horrible funk!!!! It's Monday and I couldn't even work from home. It's like my brain was sleeping. I gave up and slept for 2 hours after a full 8 hours of sleep the night before. I am normally a high energy person so I thought I was losing my mind until I realized the only change is I started Zyrtec last week and was told by the pharmacist for best results take it daily. He said for best results take it everyday whether you're experiencing symptoms or not. When I woke up I decided to Google Zyrtec side effects and it wasn't until I found these consumer comments that I know to quit taking Zyrtec!!!!! | F | 45 | 7 days 10 mg 1X day | 8/24/2015 | 1 | Year round indoor outdoor allergies | Irritability, severe depression, lethargy. | On this for probably 15 years after trying so many others that either didn't do the job of muting the allergies or their side effects were completely unbearable from the start. While Zyrtec works for the most part, I did notice that my body wasn't responding to the anti allergy effect as well- still suffered on this. Went off a few weeks ago because the depression is changing who I am - and I feel like I actually went ON an antidepressant, it's that much of a difference being OFF this drug. Into week 2 1/2 or 3 without: hands are swelling, hot and itching like crazy- feet to a lesser degree. Been reading that this is common withdrawal. We take these pills for years like its nothing but the withdrawal is evidence that we've become dependent on it. | F | 40 | 10 years | 8/15/2015 |
