 1  Allergies I took just half a pill of Zyrtec and it caused some of the worst asthma I have had from a drug (probably due to the potent antihistamine in it). This lasted for an hour and I was wondering if I would make it. I decided to never take it again after this incident. Caused asthma (just half a pill) for about an hour. I decided to never take it again. M 49 1 days

 3  Seasonal (now year-round) allergies Did not recognize any negative side effects while taking Zyrtec - was just so happy it relieved the constant sneezing, dripping and watery eyes. But then realized what others were saying about sadness, irritability, tiredness, weight gain. I had all that, too. Thought it was just my work, the kids and getting older, etc. Lately, my nose was getting SO dried out, that it was painful to touch and constantly filled with crusty stuff, like scabs from little cuts. So, I went off Zyrtec. Since getting off Zyrtec (cold turkey), after less than 1 week my nose is healing, but OMG the face itchiness!!! I never thought I'd have withdrawal symptoms! Having never experienced them before, I was really worried - my face is numb and tingling and I can't seem to stay still (restless). Now I know! Coming across this website is a lifesaver (I thought I was going crazy!). I am just waiting for all the side effects to eventually subside before I try something else. Of course, I am back to sneezing and water eyes, but it's worth a week of allergy suffering to get off this medication. Never again. So disappointing.... F 41 5 years

 1  Uticaria Tiredness...so tired all the time, dry mouth, constant urination, forgetful, tinnitus, negative thoughts, unexpected rage Initially this is a very effective drug. I guess it steps in for your immune system which may be overactive, etc,etc....(ahhh relief) .however while seemingly curing symptoms of allergies it's side effects and withdrawal for a lot of people are not worth it. I have tried several times to come off the meds without success. After 36hrs extreme dizzyness, nausea and itching begins.So I pop another third of a pill. A brilliant blog called "Quit Zyrtec, get itchy" has been removed....I believe by the drug company or forces that be. It had great tips on how to survive withdrawl. I discovered a blog called "Itchyanna " tho which details her withdrawal. I have decided that I need to begin my withdrawal during the school holidays where I'm not working & family can rally around me and support me...I will hopefully begin my own blog :called ItchyFi also...so stay tuned. Think twice before taking Zyrtec & I recommend NEVER NEVER give it to your children! Look for an alternative. Wish me luck!! F 39 10 years

 3   Tiredness, Somewhat Depressive. I was perscribed this for post nasal drip and i took it at night around 11 PM. I woke in the night, which never happens to me, at 1AM 3AM 4:30AM and 5:00AM. Each time this happened I began to get ready like it was 6AM and i was going to school. When i went to school my friends said i was really quite kind of like i was depressed and i never ate today which obviously isnt good. M 17 1 days

 1  seasonal allergies My son was given both zyrtec and flonase for seasonal allergies. It seemed to work ok when we first began them. I was not faithful in giving them all the times and usually gave them only when seasonal allergies were bad. We have finally figured out that both of these medications were effecting him negatively so we took him off them immediately. Symptoms were: stomach pain, headache, times of panic, heavy headedness, severe anxiety, insomnia, loss of appetite, weight loss and probably more that I am forgetting to list. Think carefully before giving this medication to your child. My son has been off the meds for 5 days and is feeling SO MUCH BETTER! M 10 11 months

 5  Itchy eyes, sneezing, runny nose None Zyrtec has been a lifesaver. Works much better than Claritin with no side effects. I do notice that if I miss a dose, my symptoms return with a vengeance F 26 2 years

 5  itchy skin, runny nose Sometimes heart was beating so fast that I had to stop moving to slow the heart beat. This was a few years ago. I didn't get tiredness from taking this med at that time. But a few years later, I took Zyrtec again to deal with itchy skin and runny nose, I got very, very tired and had to stay asleep all day and all night. I couldn't work. I couldn't do anything. Just sleeping and sleeping. Last night I was hungry but I couldn't get out of bed to eat because I was too weak. I skipped supper and slept. I wanted to eat, but I couldn't get out of bed and fell asleep till late morning. I think 10mg is too much of a doze for many people. Today I cut up the pill in half and took 5mg instead. Maybe because of my aging... I used to love taking Zyrtec, and 10mg didn't cause problems, but now I can hardly keep myself awake with 10mg. F 43 3 weeks

 4  Allergies Allergy relief, Fatigue, Anxiety, Heart Palpitations, Sore Throat. Zyrtec worked great for my allergy relief. I've moved recently and my allergies are not as bad so I only take it if my allergies are acting up. When I took it year round there were side effects, however, I found the side effects of other allergy medications to be MUCH, MUCH worse! I did feel exhausted when taking Zyrtec, but my allergies were so bad that the trade off was fine. I took the drug at night and slept wonderfully! It was just very hard to wake up! F 28 2 years

 1  severe year round allergies I don't even remember if there were any, because I was on it for such a short time. It didn't even work in the least bit! My body had developed a resistance to Claritin-D, so I was looking for a new alternative for my allergies. This was clearly not it! F 19 1 weeks

 1  Severe allergies allergies cleared, weight gain This year my allergies flared to the point where my skin was swelling up so bad that I was in physical pain. My allergist's solution? Shots with my allergens in them and...ZYRTEC!!! Of course it worked like a charm but I noticed weight gain and it wasn't until now that I realized zyrtec was the problem. I've always been skinny and, let me tell you, I gained 20 pounds in 7 months. I refuse to take this junk. Now I have to work off 20 pounds. G I'd rather stay inside all day next to my air cleaner than take zyrtec and gain MORE weight. Thanks a ton (literally), Zyrtec. F 18 7 months

 5  allergies None I LOVE THIS STUFF! I have had zero side effects. It is wonderful for allergies(I live where allergies are very common) and even helps me not get a headache after consuming wine(which is a blessing). I take the generic thru Kaiser. Best drug ever. I take as needed, have been taking it for years, as does my husband, daughter, mother, all my other kids, and I tell people all the time about it. A great antihistamine. F 56 3 years

 1  seasonal allergy during: feeling exhausted. after: withdraw symptons: itching, heightened skin sensitivity. I take OTC anithistamines every year from april to august for seasonal allergies ( sneezing, sore throat ). I switched to Zyrtec last year. I did not make the connection about the side effects until this year. last summer shortly after stop taking zyrtec I got itchy on lower legs, i thought it was due to stress, eventually heat rash ( after shower or exercise ) was bad too. I went back on Zyrtec for about 1 month for the itch because I couldnt stop scratching my legs and my skin got even more irritated, with tiny red rash all over. zyrtec did stop the itchy rash right away. Then I stopped taking it, and I was fine. this summer 1 week after quittng zyrtec, one day, my hands, feet, and legs got itchy. And heat rash came back too. I finally made the conection I am going thru Zyrtec withdraw. F 43 4 months

 4  severe hayfever Significant weight gain & rage. My weight gain & rage came on so suddenly & severely that I went to see my doctor. He said I was perimenopausal which made sense but these symptoms all started around the time I started Zyrtec so it seems a little more than coincidental. My allergies were so bad before zyrtec that right now I'm willing to live with the side effects unless I find something else that won't make me drowsy. I can actually tell when it's time to take the zyrtec because my nose starts pouring & I get what I call "snot induced asthma" because my nose runs so terribly that it flows back into my airway & causes wheezing. I felt like I was choking constantly. Even my coworkers worried about me. Truly impossible to function. I hate the weight gain & anger I have, but now I can go outside & jog because I can breathe & the jogging helps get out some of that rage so I guess it has forced me into a healthier lifestyle.

 5  hives Not sure I actually have any side effects, after reading all the side effects that some of these people had does make me wonder. I have never been depressed, anxious, or anything else that these bloggers are posting...bout the only thing I can relate to is the night sweating... After 6 months of dealing with hives, My wife suggested I go to the doctor. He prescribed Zyrtec. It was the best thing that has ever happened to me. My only concern is that I have been on it for so long that if I do come off of it I may experience a huge withdrawl issue. So I may attempt this soon and see what happens. If my hives come back then I will most likely stay on it until I; well either find something better or when the good Lord takes me ...then I wont have to worry about anything, it'll be all good then M 46 13 years

 1  allergies to nearly everything Severe agitation & depression. Felt like waking up in a haze ever day & the smallest things would set me off. Stopped taking it & within a week I felt happy & calm again. I'll fight the allergies rather than struggle through the way this medicine makes me feel. F 26 8 months
