| 5 | Mild Allergies | No side effects | Works perfectly, no drowsiness or other problems | M | 58 | 3 years 10mg 1X D | 2/18/2013 | 5 | I take Zyrtec for angio edema. | I have been taking Zyrtec everyday for five years. I take it at night because my angio edema seems to attack sometime in the night. I have had no side effects at all other than sleepiness. Taking it at night helps with that. Without Zyrtec I would not be able to work. My angio edema is pretty erratic. I haven't had an attack in 2 years. Without it I'd be very depressed. The swelling always begins in my face first. It is almost impossible to eat, go into public, or talk when my face and mouth are swollen. I've had attacks where my throat has swollen sending me to the ER. So without Zyrtec my life would be very difficult. | F | 33 | 4 years 10 mg | 1/10/2013 | 5 | allergies/hay fever | No side effects. | F | 28 | 4 years 5 | 12/23/2012 | 5 | general allergies (tree pollen) | none | I'm very sensitive to medication, and this one is the only allergy medication I have been able to take that does not make me want to sleep for hours or give me a groggy medicine head. I love this stuff! | F | 37 | 2 years 5 or 10 MG 1X D | 9/7/2012 | 5 | Indoor and Outdoor Allergies | No side effects at 10mg. Higher doses tend to make me sleepy. | This is the best antihistamine for my allergies. I only take it during bad allergy season or if I am cleaning the house (dust allergies). I have tried both name brand and drugstore generics, both work well. | F | 40 | 5 years 10 mg 1X D | 6/9/2012 | 5 | allergies | Sleepiness | F | 30 | 6 days 10 | 6/7/2012 | 5 | allergic asthma, hay fever, asthma | dry mouth | Zyrtec has made my asthma much easier to deal with, with other medications added, such as singulair and a steroidal QVAR inhaler daily, my allergic asthma is much more controlled. The lung specialist I was seeing wanted to place me on Xolair injections for severe, uncontrolled asthma, when I learned there was a slight chance of anaphylactic shock and cancer in clinical trials, I decided against the injectable. While taking the Zyrtec I am now able to have my 2 dogs in the house and love on them without breaking into hives, as well as eat some foods, which I use to react badly to. | F | 40 | 2 years 10 mg 1X D | 4/24/2012 | 5 | Seasonal Allergies | My children and I take Zyrtec - it is amazing! BEST STUFF EVER! | My family swears by it. | F | 46 | 5 years 10 mg 1X D | 3/29/2012 | 5 | Year round allergies-Pollen | Drowsiness-But just take it at night time and you will be fine. | The ONLY allergy pill that worked for me. I LOVE it! | F | 21 | 10 years 10MG 1X D | 10/12/2011 | 5 | allergy | no major side effect but i often drink beer when taking it and if i have beer or wine i get some of the strangest dreams they're always fun but wow there weird. | stuff works great | M | 27 | 40 days 30mg 1X D | 9/28/2011 | 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 10 mg 1X D | 9/27/2011 | 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 10 1X D | 9/21/2011 | 5 | animal allergies | none | Zyrtec has changed my life. I have been allergic to all animals all my life. Now we have 3 dogs and I am doing great!!! | F | 55 | 6 months 10mg 1X D | 8/27/2011 | 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 10 mg 1X D | 8/15/2011 | 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 10MG 1X D | 8/5/2011 | 5 | seasonal allergies | I take Zyrtec as needed (not daily). It relieves my itchy eyes, runny nose, sneezing and generalized crappy feelings. | F | 28 | 3 years 10mg 1X D | 7/21/2011 | 5 | severe allergies, asthma | rarely dry nose, but a hell of a lotbetter than a runny one! | This medication is AMAZING for allergies! love it | F | 14 | 3 years 10mg 1X D | 5/10/2011 | 5 | Itchy Hands and Feet | None that I can tell, except the relief from itching. | I've been reading all the negative reviews about Zyrtec because after 2 years I find I actually need to increase the dose to have the same effect. I spoke with my doctor first and went ahead with the increase. I decided to check what people were saying about it. For me, Zyrtec has been a miracle drug! Before I took it, I itched so badly that I couldn't sleep. It has completely removed all of my symptoms. My hands and feet (and ankles and wrists) used to itch so bad that I was scratching myself up trying to get relief. Now that I have Zyrtec (actually, I take the generic Aller-tec from Kirkland), I sleep at night and can wear my rings. I do get night sweats, but who knows if that is from this drug (I'm 47 years old). I'll take the night sweats over the itching if that comes from the drug. I take one 10mg pill every night. My only worry is that it will stop working one day. I used to take Claritin, but it became completely ineffective after about 6 mos of regular use. Zyrtec has continued to work for 2 years of regular use. So we'll see... | F | 47 | 2 years 10 mg 1X D | 3/30/2011 | 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 D | 3/17/2011 | 5 | Hives | Fatigue | Yes, Zyrtec makes me tired, but it is certainly better than being covered in hives! It has been extremely efficient at curing my itchy skin (but less effective for nasal allergies), and I am very happy with this drug. | F | 43 | 365 days 10 2X D | 1/18/2011 | 5 | Seasonal allergies | none | It works, quickly and effectively, where all other non-drowsy antihistamines have failed. I take the generic Walgreens/CVS/Wal-mart version as needed (about once or twice week during the winter) and stop sniffling/sneezing within fifteen minutes! As a side note, I try not to take any medication regularly unless it's absolutely necessary, to protect against potential dependency or cumulative side effects. This may influence why I have nothing negative to report. | F | 26 | 1 years 10mg 1X W | 12/7/2010 | 5 | seaonal allergies, digestive issues | Was told to have my son take it at night, just in case it made him drowsy, but we didn't notice any increase in drowsiness. | Zyrtec was wonderful for our son. He went from having 2+ weeks of unbelievably runny noses every time he caught a cold, to just normal symptoms of a few days. He also felt a great lift to the almost constant depression he had been feeling, and it cleared up the gastro issues he had been having as well. We took him off Zyrtec and put him on Claritin and it just didn't do the job. I see a lot of negatives on here about Zyrtec, but for our son, it made such a positive difference in his life. | M | 16 | 4 years 10 mg 1X D | 11/18/2010 | 5 | No side effects, only that it takes about an hour and a half to kick in. | I started with an uncontrollable itch all over my body, after taking ZYRTEC, I have been just fine, I only take it when needed. | F | 40 | 1 years 30 MG 1X AN | 9/30/2010 | 5 | allergies | moodswings, drowsiness | I've been taking Zyrtec off an on for seasonal allergies since I was a kid. It's the only thing I could find that really helps with the minimal side effects. HOWEVER, If i take zyrtec too late a night i just cant get up in the morning. so obviously i suffer drowsiness with it. Also, I get really moody and sensitive a few hours after taking it. I find taking it at about 8 PM is best.. I'm asleep before the moodiness sets in, and I'm able to wake up on time. Abiding by these rules I'm fine with it | F | 21 | 13 years 10mg 1X D | 9/13/2010 | 5 | All year around allergies | none | First I would like to say is, Why would you give children an over the counter med without a Dr's approval. There are many over the counter meds for children but I wouldn't give my child it without an ok from the Dr. I love Zyrtec. I have major allergies and have tried everything. Over the counter, rx from Dr and nothing helped. Then one day a Allergy Dr gave me a sample of Zyrtec. It was new on the market. I loved it! Won't take any thing else. and when they can out with their eye drops I was in love all over again. Again before Zyrtec eye drops I tried all the rx drops, all the over the counter eye drops and my eyes still itched. My eyes itched so bad I have scars on my eye lids from rubbing them. One drop of Zyrtec eye drops and the itch was gone. I found heaven all thanks to Zyrtec. Thanks Zyrtec, your #1 in my book. | F | 53 | 10 years 10 mg 1X D | 9/13/2010 | 5 | to meet people | I fell in love with the first thing I saw. I'm sure glad I took it on the first day of college and not back when I lived with grammy and gramps. | It is a love potion! beware of it's effects on arousal. Also, stops my itching and cat allergies. | F | 31 | 1X D | 8/24/2010 | 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 D | 8/20/2010 | 5 | Seasonal Allergies | None noticed. Doc suggested daughter take this at night as some experience drowsiness. She does take it then, but have not seen a 'drowsiness' side effect. | This drug has been a gift to my daughter. Summer of 2009 (pre-allergy-diagnosis) was a nightmare. Daughter coughed all summer long...many trips to doc. End of summer finally diagnosed with allergies. Put on Zyrtec and a nose spray and we finally had our 'normal' daughter back...including sleeping better as she wasn't coughing all of the time. Takes it only during allergy season...stops at first freeze and starts again about mid-March. Summer of 2010 has been GREAT for her! | F | 12 | 1.5 years 10 MG 1X D | 8/20/2010 | 5 | Seasonal and pet allergies | None | Zyrtec has been the only allergy medication that has worked for both seasonal (pollen/dust, etc) and pet allergies. I have never suffered from any side effects from Zyrtec and I love it. I was taking the prescription pill, then the prescription liquid when my insurance no longer covered the pill, then I switched to the OTC Zyrtec when you no longer needed a prescription. They have all worked exactly the same. | F | 28 | 10 years 10 MG 1X D | 8/16/2010 | 5 | Allergies | Some drowsiness as mild "hangover" in the morning on full 10 mg dose. | I was on Claritin & Nasalcrom for awhile and found them to be only fair in controlling my often nasty allergies. Went to an allergist, had standard arm pin-prick test done which only confirmed what I already knew about my sensitivities, and was given Zyrtec 10 and Nasonex, both for daily use. It was an unbelievable improvement. Only issue was next day drowsiness, which I've nearly eliminated by taking 7.5 instead of 10 mg (tricky cutting the tablets though; and, 5 mg was not quite enough) and doing so 2 hours before bed rather than right at bedtime. Unexpected benefit was a reduction in some social anxiety I've had off and on for years, which I believe is due to a residual anxiolytic effect of Zyrtec/cetirizine as an Atarax/hydroxyzine metabolite - can't find substantiation for this anywhere but I don't think it's my imagination! | M | 50 | 14 days 7.5 mg 1X D | 7/28/2010 | 5 | allergies | None | Stops my allergies, but over years I have to take more Zyrtec pills to make the same allergies to go away.... | F | 46 | 14 years 10mg 2X D | 7/23/2010 | 5 | ADHD | During the time of my journey through life, I had noticed that every time I played video games I would only go for body shots, but after taking Zyrtec, all I would want to get were HEAD SHOTS. I felt extremely angered by normal everyday noobs. After I started taking Zyrtec I wanted to PWN them like they have never been Pwned before, and I still have ADHD!!? whats up wit dat? Head Explosions Public Urination Every time I get a gun in my hand, it automatically points to someone's head. Uncontrollable peanut butter texture of my stool Speaking Ebonics Black Rage The plague | Zyrtec gave me AIDS. | M | 12 | 20 days 10mg 2X D | 6/30/2010 | 5 | seasonal allergies | None | I'm posting to counter many of the negative comments which can be attributed to other factors, and to counter the the self-selection bias. Sure I've had dizziness, problems falling asleep, and hair loss, but all of these occurred long before I started taking Zyrtec! In the interest of full disclosure though, I only take enough to counter 95% of my symptoms so I'm not "flying blind" and risking overdosing. | M | 33 | 1 years 2.5 to 5mg 1X D | 6/21/2010 | 5 | Apparent allergies | I had no side effects at all from this drug. Sure if I sat still and did nothing I would get drowsy. I would take this medicine at approx. 1-2 pm each day. (after already being awake for 5-7 hours. So I think it was just mid day drowsiness. This stuff worked great compared to how i was suffering before taking it(cold like symptoms). One reviewer complained of suicidal thoughts, another said irratibility and bad/weird dreams? Sounds to me like you folks were taking Chantix or some other drug to help quit smoking since those are definitely side effects listed on Chantix/Zyban sheets. | I should add I began the attempt to quit smoking about the same time my "allergies" manifested themselves, so maybe the two were related. I havent had allergies since I was a little kid. I stopped taking the Zyrtec about two days ago and have not noticed any change in anyway so far as allergy symptoms coming back. Im thinking it was just a fluke as I was cleansing my body from 20+yrs of smoking. guess I will see in the coming week or so as the Zyrtec leaves my sytem. | M | 38 | 45 days 10mg 1X D | 5/31/2010 | 5 | Allergies | None. Ever. In 10+ years of taking the medicine, from brand name to generic Kirkland and Equate versions when it came off-patent. | You people are nuts. Part of the human experience explains many of the "symptoms" that are being stated here. We all have our up and down days, but guaranteed if you kept a log of what happened and when in relation to your taking medicine (of course over a relatively long period of time), you'd unlikely find any trend suggesting that the drug creates these symptoms. I still get headaches when there are large atmospheric pressure changes, and get a little bit of a runny nose in the winter. Zyrtec helps me day to day, but in the heaviest of allergens (or even unknown events) benadryl or sudafed are the way to go. There are no panaceas for any disease. I know you all believe that the big corporations are lying to you as part of some crazy mind-control scheme, but perhaps you should take a venture into reading the literature on the drug. Just google "uspi_zyrtec.pdf" for the data sheet. The data sheet states "Most adverse reactions reported during therapy with ZYRTEC were mild or moderate. In placebo-controlled trials, the incidence of discontinuations due to adverse reactions in patients receiving ZYRTEC 5 or 10 mg was not significantly different from placebo (2.9% vs. 2.4%, respectively)." That means that there were NO patients in all 6000 patients who felt uncomfortable or experienced uncomfortable enough symptoms to stop treatment that could have been explained by more than random chance. | M | 25 | 10 years 10mg 1X D | 5/24/2010 | 5 | seasonal allergies | none | No side effects, seems to work well. Zyrtec D is also good for those times when your allergies combine with a cold and you get a higher level of congestion. | F | 38 | 10 mg 1X D | 5/14/2010 | 5 | Year round allergies | I haven't experienced any noticeable side effects. | I have been taking zyrtec for about 3 years. I am allergic to trees, grass, weeds, dust, mold, and animals. I had never been able to sleep with my mouth closed before I took Zyrtec. I also had very sensitive skin which was almost always itchy and would welt up when I scratched it. I couldn't wear any kind of lipstick/chapstick with color or flavor because it gave me a sore throat and made the area around my mouth turn red. Zyrtec has not completely cured my night breathing problems, but it has made them tons better. The biggest difference is that I am rarely itchy. it used to be that once I started scratching, I couldn't stop and sometimes, I would end up bleeding. I am so happy not to have to worry about that anymore. My skin still welts up if I scratch it, but I hardly ever do. I also don't have to worry about wearing chapstick or lipstick. On top of that, my seasonal allergies have gone away. Zyrtec has been great for me. | F | 21 | 10 mg 1X D | 4/29/2010 | 5 | Asthma/Allergy | It "cured" my asthma symptoms, except for the once a year bronchitis. I LOVED how it worked, but started noticing extreme mood swings, menstrual problems, and weight gain...about 15 pounds in one year | Just stopped 3 days ago, already feeling better, less "foggy" and less moody. Actually have energy! | F | 41 | 900 days 10 1X D | 4/19/2010 | 5 | allergies | none | so far it works great | M | 49 | 5 days 10 mg 1X D | 4/16/2010 | 5 | seasonal allergies | I started to feel drowsy/tired, but I think it was a combination of the fact that I had taken it at the end of a long day of non-stop sneezing. The allergies had exhausted me and the Zyrtec maybe just completely relaxed me into sleep. | I only take Zyrtec about once or twice a season. It is usually enough to get me through. I'd say I have moderate symptoms but then I'd have one day where I cannot stop sneezing and tearing and at that point I take a Zyrtec (I'm afraid to take it too much). I'll then be free of symptoms for a good 4-5 days. It'll come back, but it won't be severe. On those days I do a saline nose spray and otherwise am able to live with it without suffering too much. Regarding children, I have given my 6 year old the child's Zyrtec formula. But I do a much lower dose - I give him *slightly* more than what is prescribed for 2-5 year olds. The teacher reported that he had a sleepy morning that day but otherwise we saw nothing else, and my son said he felt so much better. In his case too the relief lasted several days. | F | 41 | 1 days 10 mg 1X D | 4/13/2010 | 5 | Severe, Year-Round Allergies | none | Zyrtec is the only allergy drug that has worked for me. Claritin and Allegra do nothing to relieve my itchy throat, eyes, and nose. There are warnings of drowsiness, but I have not experienced this, nor any other side effects related to taking this medicine. My major allergies are every type of grass, oak and pine pollen, seasonal weeds, cats, shedding dogs, dust...you name it, I'm probably allergic to it. March and April are the absolute worst months for my allergies, and Zyrtec helps to minimize my torment, though, during these months, Zyrtec cannot completely eliminate my symptoms. | M | 26 | 5 years 10 mg 1X D | 4/6/2010 | 5 | hives | Heart pounding, vivid dreams, dehydration | I have a lifelong history of allergies and upon turning 40, possibly entering perimenopause, my allergies worsened. I have continued to take zyrtec after it being prescribed at Mayo Clinic. At times I was able to go down to 5 mg once a day with less side effects. Initially while at Mayo I asked "How will I ever get off this?" because of the rebound reaction every time I tried. The doc replied, "with an eye dropper". I think when I was in my forties the reaction to it was not so severe, but upon entering actual menopause, taking it at night has compounded my menopause symptoms. I am seriously looking into going to the desert (low allergen) to try a taper or wait until winter, maybe even trying acupuncture to help getting off it, because in a sense I am addicted to it. Until then I am trying taking it during the day to reduce the night symptoms and drink a lot of water. Any menopausal women experiencing the same? I would love to hear if someone has effectively switched to something better. | F | 53 | 13 years 10 mg 1X D | 3/31/2010 | 5 | Hives | No noticeable side effects | My daughter had a horrible outbreak of hives when she was just a little over a year old. It happened over the weekend and the ER doctors didn't know what it was. We took her to a dermatologist the next Monday morning, he diagnosed hives. My daughter was taking Zyrtec, Xantac and Benadryl for several weeks to quell the outbreak. She was then put on 1/2 teaspoon of liquid Zyrtec a day to prevent further outbreaks. After a few months we stopped giving it to her, soon after she broke out again. She is now 2 and a half years old and is back on Zyrtec daily, she is doing just fine. She takes it at bedtime. I see no difference in her sleeping pattern or behavior on or off the medication. From the looks of what I have been reading about other children on Zyrtec, I now feel that we have been very fortunate with our daughter. If she would have had adverse effects I would definitely have stopped it. Though, I am concerned about the long term effects of prolonged usage, effects that may not be visible at this time. | F | 2 | 1.5 years 1X D | 2/28/2010 | 5 | Allergies | I think zyrtec is a wonderful drug. It keeps me symptomless when I am on it. A doctor told me once that it is too strong and can cause bacterial infections in the sinuses. So I sometimes only take it every other day. I have been very happy with the results, especially since loratidine and allegra do not work at all. | F | 55 | 10 1X D | 2/11/2010 | 5 | Asthma, respiratory issues | My 11 year old takes this medication. No side effects at all when she takes it at night. Some slight drowsiness when she takes it in the morning. | This medication has been a blessing. My daughter used to miss school all the time becuase of respiratory issues. Her asthma was getting worse and lasted longer. Our doctor first suggested inhaled steroids but we tried zyrtec first and it has been a miracle for her. NO asthma for 6 months so far. This is unheard of for us. I have seen no negative behavior changes. If anything her behavior, mood, and concentration have improved significantly. I can only attribute that to the better health this drug has given her. | F | 11 | 6 months | 12/17/2009 | 5 | nasal allergies | I've taken Zyrtec for years with great results and have experienced no side effects. | Some of these postings are probably right for some people, but some of them are "out there". | F | 52 | 3 years | 11/12/2009 | 5 | Allergies -Cough, Asthma | Only take in the evening because of drowsiness. Some dry mouth also. | I have been on various medications to find something to stop my allergic post nasal drip which produced a constant dry cough and asthma for the past two years. I tried Nasacort, Depomedrol shots, Claritin, Advair, and numerous other medications which either did nothing or had horrible side effects. Zyrtec finally has me functioning normally again! I have had to figure out the right dosage and that was 5mg every other day. I take it in the evening since it does make me very drowsy but I am fine in the morning. Zyrtec is great. | F | 47 | 1 months | 10/30/2009 | 5 | itchy skin and allergies | No side effects. This drug is a wonder for me. | I love this drug. Nothing else worked for me. My itchy skin depends on it. I have to take it everyday or I am miserable. I have no side effects and am thankful since I see so many negative responses. I'm not anti-social, not depressed, not irritable, no panic attacks, no bad dreams,etc. Looks like I"ll be taking this drug for as long as it helps me. 10 years and couting. I'm very glad it's OTC now. | F | 29 | 10 days | 10/28/2009 | 5 | seasonal allergies | no side effects. controls allergies without making me drowsy. | F | 45 | 4 years | 10/2/2009 | 5 | Chronic urticaria | no side effects | Zyrtec controls my hives along with Allegra without making my heart race. | F | 58 | 5 years | 9/19/2009 | 5 | I have suffered from seasonal allergies my entire life. I felt like I finally found a cure when I started taking Zytrec D. It was wonderful! HOWEVER, when I stopped taking the drug after allergy season, I had mind-numbing headaches, couldn't concentrate, severe panic attacks, beyond tired (and then, as if it was torture, insomnia at night), vivid dreams, no appetite, numbness, shallow breathing -- I am 24 years old and I feel like I have no energy!!!! This withdrawal is killing me! | I have stopped taking Zytrec D for over two weeks and I am still experiencing these symptoms. Please --- how much longer will this last??? I have been taking vitamin and herb supplements to help heal, but nothing is working! HELP! | F | 24 | 1 months | 9/2/2009 | 5 | Various allergies | None | I am happy using this drug. With other antihistamines I have experienced side effects, but Zyrtec works fine for me and relieves symptoms relating to food and air born allergies. | M | 47 | 3 years | 6/14/2009 | 5 | allergies | I don't believe there's been any - sleeping rather hard, dreaming alot. | Never had any allergy issues until this past winter - tried Claritin and others - Zyrtec did the trick, if I stop taking it, I start right back up with the symptoms - looks like a long term thing for me. So far, no issues that I can tell. | M | 49 | 9 months | 6/12/2009 | 5 | summer allergies | Drowsiness, dry mouth | No weird problems. For most people, Zyrtec works great. For some people, most of whom have posted on the website, it causes problems. The effects aren't permanent. Try it and see if it works. If it doesn't, don't take it. | M | 37 | 4 weeks | 5/20/2009 | 5 | Allergies,sinus pressure,itchiness | No side effects. | Zyrtec has provided better relief from allergies than Claritin. It has even reduced my allergic reactions to cats. The only time I had a problem was when I was taking benadryl, on occasions of visiting my girlfriend (who has a cat), in addition to the Zyrtec. That cocktail caused eustation tube dysfunction for some time. I avoid mixing my antihistamines nowadays. However, Zyrtec, by itself, never caused me any problems. | M | 39 | 2 years | 5/18/2009 | 5 | seasonal allergies | A little hyper, decreased appetite | I took this medicine about 2 years ago, but i was also taking antidepressants and didn't notice side effects. but now i'm just taking the over the counter zyrtec and i have a decreased appetite, which is great bc i tend to eat to much and am wanting to lose weight. and i am a little jittery, which is ok bc i usually don't have much energy. I would never give this too my kids tho...especially after reading the reviews | F | 26 | 2 days | 4/3/2009 | 5 | cold urticaria(hives from cold) | weight gain and increased appetite, ( but I started taking it over the holidays.) Dry eyes in the morning and maybe some joint pain in my hands. | I have suffered from cold urticaria since I was 16 (now 45). It cycles through every 7 tears or so, so I do have some years when I don't get them. I have to say that zyrtec has been a miracle drug for me. I will deal with the weight gain. for me, nothing beats being itch free. My dr had also prescribed zantac which acts on a different histamine receptor site than zyrtec, but I haven't needed to use it yet. I guess sometimes the effects of zyrtec(which I beleive is an H1 receptor) wears off after a while which is why she prescribed the h2 receptor drug. | F | 45 | 3 months | 3/18/2009 | 5 | indoor alergies | None. maybe a little tired, but I take it at night. 10mg | I love animals. and if it wasn't for Zyrtec I wouldn't be able to lay with my cat at night or survive cleaning the house due to all the dust. It is an amazing thing that I just simply cannot live without. I have been on claritin too, doesn't work... for me. | F | 19 | 5 years | 3/11/2009 | 5 | allergies | first few times I was nauseous and extremely tired but it was the only medicine that helped me last through the day without having an attack. In the past 3.5 years I have experienced weight gain, decreased libedo, tiredness after taking the pill (I take at night) but then wake up regularly during the night. | As I will be starting fertility treatments in a few weeks, I stopped with the medication 2 months ago. I had found some very positive reviews regarding a vitamin called 'Quercetin' on the internet and so, I began taking it (in combination with vitamin C). I started with taking 4-5 tablets a day (my allergies are extremely high and year round), a month ago, I was down to 1 a day and I am amazed!! I am 39 years old and have been taking allergy medication / shots / drops since I was 16 and this vitamin (it is found in the skin of apples and red onions) really works!! and without all the wierd side-effects of the other drugs.... I have become a HUGE fan! | F | 39 | 3.5 years | 2/11/2009 | 5 | Severe Allergies | None, I am an energetic morning person and I stay up until 11pm most nights and I sleep blissfully. I am not overweight and people tell me how wonderful my personality is. I surprised to see so many adverse reactions. | I have tried every drug out there. Zyrtec (Cetrizine Hydrocloride) works for me. I actually have to take 10mg every 12 hours (Doc recomended) and when Cedar Pollen is very high up to 3 doses (30mg total) spread over 24 hours. I never seem to have any of the possible advertised symptoms. | M | 41 | 4 years | 2/6/2009 |
