| 5 | allergies, intense ear itch | increased appetite, drowsiness | Zyrtec is a wonder drug. Sure I have vivid dreams. I have had them my whole life - 20 years before Zyrtec. Come on people. Zyrtec has changed my life. Not only have I gotten rid of a daily intense ear itch (apparently from unknown allergies), but I also developed more severe allergies last year, and taking Zyrtec-D has rid me of the symptoms. Also, I have noticed that when getting a cold, Zyrtec helps immensely and I can function normally. It does make me very tired, which is why I take it at bedtime, and I wake up just fine and my allergies stay away all day. Usually I just take 1/2 pill (over the counter). If you have any of these problems, PLEASE try this drug. It really works. You can find ways to get around the drowsiness and hunger pretty easily. Take at bedtime and eat healthy! Side effects will occur with any medication. These are very manageable and SO much better than allergies!!! | F | 29 | 8 months 10 1X day | 8/20/2010 | 5 | Chronic Hives | I didnt relialize ther were any symptomes | My 3yr.daughter has been suffering with very puffy and itchy hives all over her body since last summer , I didnt know what to do or to give her. So we went to her doctor and she just gave her benyadryl and said it was a allergic reaction from something she ate. But they got worst evey day ,changing in size ,in color and in size. So they finally recomended me to a allergist but he just made me write a diary for 4weeks to see what she eats ,what type of soap she uses ,etc. And made me give her more benadryal but 4 times a day this time but the hives got 2 times worst , knowing something is wrong I stopped the medican realizing that she is allergic to benadryal ! (Long story short) - We finally switched her to zyrtec amd I really thanked God for this medican Because since the first.time she took it the hives completely stopped. BUT..... The last few months she has been going through the same thing that everyone else is going through on this site : Being out of control angry ! , can't sleep , night mares when she does , does not listen, . rapid weight gain . ( 5lbs in 1 month thats alot for a toddler) I thought it was just a faze she was going through a toddler stage maybe. But I recently stopped her from it, now knowing it was the carpet she was allergic to. And now I know that it was the zyrtec that made her act that way . I feel so bad that my baby had to go through this. Thanks for the site. But dont rule zyrtec out yet it did work fast just make sure you m | F | 29 | 6 months 10 1X day | 3/17/2011 | 4 | Severe allergy symptoms | First, let me point out that my allergy symptoms for the most part were "cured". I have been complaining lately of extreme fatigue and weight gain in the belly area where I have NEVER had an issue before. Last night my husband pointed out that I began complaining about these things after taking Zyrtec. I looked at my calendar, and he's right! I've reached out to my doctor to look at other options for treatment. In the mean time, I skipped my Zyrtec does last night, and do not plan on EVER taking it again. I realize that everyone reacts differently, and I would recommend this product to others. I do feel, however, that the makers of Zyrtec should include a "journal" of sorts for their customers to use and track changes to their mood, behavior, energy level, and figure. Actually, I plan on keeping a journal from now on when ever I try a new drug or homeopathic approach. It's just plain scary to think how these side effects can sneak up on you... | F | 29 | 2 months 1 pill 1X day | 5/26/2011 | 4 | chronic allergies | brief sluggishness, dry mouth. | Nothing ever worked for my allergies. Claritin had no effect. Allegra helped a little, but upset my stomach. Zyrtec is (in my opinion) the best. After reading other posts I had to jump in and sing some praises. I've had no change in sex drive. I've had no change in sleep patterns. I was foggy for a day or two when I started taking it, but that passed. The dry mouth went away also. I think its a matter of body chemistry and specific allergies. For my scenario where everything makes me itch and sneeze, zyrtec works. I've been on for 2 years, and was on a few years prior to that... there was a lapse of time where my insurance didn't cover it and it wasn't OTC yet where I suffered. | M | 29 | 2 years | 4/8/2009 | 4 | allergies | just dry mouth | I'm one of the few lucky people who are not sedated by zyrtec. In fact I am more tired when I don't take it, due to the allergies getting worse. It doesn't work as well for the past few years, but still better than anything else | F | 29 | 6 years | 5/25/2008 | 3 | Skin irritation(itchy),running nose | I noticed that my skin is getting dryer and dryer... My skin(feet) almost crack after taken for 3 days. | I found horrible rating at this website. Therefore, I decided to try to avoid taking this pills if not necessary. I feel so sorry to my kid, I gave him zyrtec(syrup) when he was about 2 years old. I didn't notice the side effect on him at that time... Now I realized this med is not as good as I thought.... Yet the doctor told me that I could give him zyrtec throughout a year.... I was harming my son... | F | 29 | 1 pill 1X day | 11/23/2011 | 3 | Pet and seasonal allergies | Brain fog, some fatigue, irritability | Been on generic Zyrtec daily for about two weeks now, decided to replace Allegra-D with this after Allegra went OTC and became far too expensive for me to justify. Zyrtec works much better on my allergies than Allegra ever did, but this improvement has come with some unpleasant side-effects. Most notably I feel like I'm in a "brain fog" much of the time, often feel lethargic and disinterested as well. This in turn makes me kinda crabby, which is not my usual style. Friends, family, and coworkers are always asking why I look so tired and I sheepishly explain that it's my new allergy meds - hopefully they don't think I'm trying to explain away a drug problem of some kind. My dad's a PA and says my body should adjust eventually to minimize the side-effects, but there's also a chance it won't... we'll see. All I know is that it's great to be able to be around my own dog without feeling like someone threw sand in my eyes and throat - that alone makes it worth the "price of admission." Hopefully I'll adjust to shake the fog and things will be even better. | M | 29 | 14 days 10mg 1X day | 12/14/2011 | 3 | Food allergies | Drowsiness; would be lethargic and tired the day after taking it; would always crave sugar the day after taking it | Yes, it stops the itching, but the fatigue it brings on is a huge negative. It was enough to make me stop taking it altogether, and guess what happened when I did? My allergic reactions have almost disappeared completely! It's worth pondering whether those were true allergic reactions or withdrawal symptoms. | F | 29 | 5 years | 8/23/2004 | 3 | Allergies | dizziness; anxiety (after a few days on Zyrtec-D); numbness | I've had allergies since I was 10 years old. Most of the time I went without medication, but in recent years I've developed more serious problems (example: bronchitis) if I haven't addressed them with remedies early on in the season. Allegra put me to sleep, and Claritin was okay but didn't seem to get rid of all the symptoms. Zyrtec definitely cleared up the symptoms, but the cost of stress and anxiety that it produced were too much for me -- I'm back on Claritin and much happier. | M | 29 | 2 weeks | 4/19/2006 | 2 | allergies | fits of intense anger | I've been taking zyrtec for a while and it works alright with my allergies - nothing ever gets rid of all my symptoms. But the symptoms were bearable. I began getting really upset about things and having boughts of anger where I would yell, slam and hit things - not usual for me. My boyfriend said I needed to stop taking whatever "drugs" I was on and the only things I'm on is my birth control - same for the last decade - and the Zyrtec. It only then occurred to me that maybe the Zyrtec is the problem so I am going to stop taking it for a while. | F | 29 | 6 months | 10/2/2007 | 2 | allergies | low-libido, mood swings, irritability, depression, extreme exhaustion, migraines/headaches, weight gain | I am so glad it is not just me! I didn't take it last night for the first time in weeks and I woke up like I used to today. 5 am, HAPPY and ready for the day! I started taking Zyrtec OTC again last spring upon recommendation of my allergist. I took this medication ~10 years ago also. This time around- the first few weeks were ok, it really helped my increasing allergies to things including photo-sensitivity hives. However, I put on 8 pounds in the first 4 weeks and another 3 in the last 2 weeks. I started getting migraines and frequent headaches always at 530 pm (I take it at 10pm) I could never get enough sleep. I never felt awake and the past 3 weeks my libido went to the crapper. In the last week I started these mood swings, I felt like the world was against me, I yelled at strangers if the spoke rudely to me, I have been crying at the drop of a hat. Looking back to my experience from 10 years ago, I was 19ish and I chalked my migraines, sudden weight gain, crying and everything | F | 29 | 2 months | 6/13/2008 | 1 | seasonal allergies (e.g. pollen) | Drowsiness!!!! The drug relieves allergies, for sure, but at the cost of passing out 3-4 times a day from exhaustion. It also appears to cause slight heartburn. Won't take again. | M | 29 | 4 days | 6/11/2008 | 1 | Seasonal Allergy | Terrible heart buring and palpiltation! Sever sleeplessness; Ichying, nausea, burp | This is a very very dangerous medcine if so many people in the from report the similar side effect experience. I really do knwo how it can be OTC drug. | M | 29 | 10 days | 7/1/2008 | 1 | Allergies | I am unsure if it is Zyrtec but I know for a fact that when my daughter took Zyrtec she began exhibiting violent outbursts, temper tantrums, mood swings, hitting, kicking, screaming at school, towards her friends, and sometimes me. | F | 29 | 60 days | 6/3/2009 | 1 | ALLERGY | SLEEPY SLEEPY SLEEPY! | This thing makes you SLEEEPPYYYYYYY!!!!! | M | 29 | 2 days | 8/31/2009 | 1 | For extreme cough at night | Cause extreme fatigue , brain fog , can't take decision , feel unbalanced , depression and sadness with no reason (be careful when taken) | Awful experience | M | 29 | 2 days 20 Mg 1X day | 2/5/2022 | 1 | allergies | Um, allergies. | Does Zyrtec even work? | M | 29 | 4 months | 8/11/2003 | 1 | allergies - pollen, smog, animals | extreme sleepiness, extreme dizziness, loss of clarity and memory, stomach aches, vomiting | I would need to sleep at least 15 hours a day, and then I would still be groggy. I would forget basic functions (like typing), severe stomach aches that were followed by vomiting. | F | 29 | 20 days | 6/17/2007 | 1 | Severe Chronic Hives & Allergies | Extreme drowiness, dry mouth, fatigue, weight gain, unable to concentrate | I hate this medicine with a passion! So, it gets rid of my hives and allergies, but it is not worth it. I hate walking around all day lot a zombie. And it is not safe to drive at all. | F | 29 | 1 days | 5/30/2006 | 1 | Allergies | At first, extreme increase in hunger; could only think about food! Later, abject depression, total loss of self-worth, crying spells, loss of motivation. When I stopped taking it, I developed a hypersensitivity to any antihistamine that caused extreme anxiety. | This drug literally ruined, and is still ruining, months of my life. I am now on Clonazepam and Abilify and still severely depressed; I can't seem to enjoy any of the things I used to and all I want to do is lie in bed. My sense of self-worth is still gone and everything seems hopeless. I used to be a very cheerful, positive, roll-with-the-punches sort of person, and now she has been replaced by a humorless wreck. I'm amazed that an antihistamine could do this, and that given the number of similar stories here, that the drug company denies that it could cause these problems. Obviously, it does, and more warning should be given to patients about the potential disaster this drug can make of your life. I so wish I could go back in time and never put this horrible substance into my system. | F | 29 | 2 months | 12/20/2006 |
