 1  seasonal allergies After trying to wean myself off of the generic Zyrtec once allergy season had passed, I had trouble sleeping. I would wheeze and/or cough. If I fell asleep, I would wake up 2-3 hours later and go take an allergy tablet, which would alleviate my breathing within an hour. This isn't how previous over-the-counter allergy medicines worked for me, so I called the manufacturer and reported that I believe I have an addiction. I would not recommend it after researching the public's reaction to taking this drug. I feel like I have to go to an allergist now to get off this drug and manage my allergies otherwise. In the past, I only needed allergy medication in the spring, late summer, and fall. F 44 5 months

 5  Severe Allergies I have had a few of the symptoms but never connected the two. Heart palpatations when under alot of stress, some hair loss, but since on multivitamins and DanActive has restored new hair growth, some vision blurring on and off, can not take at bedtime because I don't sleep well, take in morning with my tea to prevent sleepiness - no other caffiene drinks during the day or night consumed, only water, milk and juices. Been on zyrtec for about five years and during these past few years I have been able to eat foods I have been severely allergic to in strides. I DO NOT recommend anyone doing this without the consult of your doctor, my family says I am playing russian roulette here. I am free of any allegy affects of all kinds. I also exercise running, jump on trampoline and swim. I also use flonase nasil spray sometimes before I fly for my ears and when I think the zyrtec is not effective enough (very few days of this occurrance - three times a year average). I am sure not everyone can have the pleasure of zyrtec working for them - but from what I read it seems to help the majority. It could be possible the side effects are allegic reations to the medicine. Not all allegies are hives, eye & nose watery and ichy and shortness of breath, it could be vomiting, lethargy and bowel problems (IBS symptoms)as well. I have experienced this from food allergies on many occassions. F 45 5 years

 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

 4  Chronic allergies I've been taking it for more than 5 years. I also use rhinocort and an albuterol inhaler the three of them improve my life significantly. For the last couple of years, I've been taking them every other day as opposed to every day. Recently, I've been getting hives and severe itching spells. I went back to daily, and initially the hives became less severe, they now are getting worse again. A lower dosage is an over the counter drug in Canada and theres's a generic form of it as well - in Canada. M 45 5 years

 4  Auto Immune Disease I Take Zyrtec (2) times a day both 10 mg. I also use singular and bendryl no dye 4 times a day. I am having some troubles with Zyrtec. My itchiness appears when I go to bed and I can't sleep. My doctor says this is normal that I need to just learn how to relax. I say let the doctor relax, he doesn't experience what we experience. Now the doctor wants me to go on depoxen that will help with my hives also. Oh boy! I think I will just stay on Zyrtec, it does help. F 45 1 years

 3  Dermatographism/hives/allergies Me: sleeplessness, maybe weight gain, memory loss, concentration problems. Maybe hives worsened by stopping meds Daughter: sleepy I have taken this for about 10 years to treat hives/dermatographism (I can not go un-treated or I do nothing but scratch continuously) and mild allergies. Zyrtec is the only thing that has worked for this long, other meds have stopped working after a year or so. Daughter (5) has taken it for 2 weeks for post-nasal drip/snorring/ causing sleep disturbances. My daughter finally has an easier time falling to sleep and will now sleep through the night. It controls my dermatographism/hives as long as I take the next dose within 28 hours of the previous dose. I tried switching from taking in AM to PM, but couldn't sleep even after taking a sleeping pill. Wonder, after reading the comments on this site, whether this med has caused or worsened my weight gain, concentration/short term memmory problems, depression/anxiety. I never made the conection. Also wonder whether I can ever get off of it since it may actually be causing worsening hives/itching symptoms when I miss a dose. I am also F 45 10 years

 3  Allergies I have been taking Zyrtec for 10 years or more. It does help my allergies, but I have been having pain in my right side around my gall bladder area. I have seen the doctor repeatedly for this pain. Many tests later, I found this web site. I have stopped the zyrtec 1 week ago and so far the pain is gone. F 45 10 times

 3  Allergies (pollen and mosquitoes) Fatigue, mild depression, moodiness It works on the allergies but the side effects are unpleasant. It depends on how bad your allergies are. I still take this about once a week in the summer if I spend an evening outdoors so the mosquito bites will not turn to hives. I also use it for a few days in a row if I have an acute pollen allergy attack. If you are so miserable from your allergies that you are tired and depressed, it is worth it to feel better physically and then the mild to moderate side effects (if that's all you have) are worth it. If you can be happy while having a full blown allergy attack, then I say don't take it. F 45 1 years

 3  allergies Just classic drowsiness and feeling mentally fuzzy - but probably just due to being so drowsy. I could not take this med again unless I had a really severe allergy attack, because, even with 4 cups of tea, I can't tolerate the tiredness. :/ Took this for the spring allergy season - eyes and skin itching like crazy, congestion etc. Zyrtec works fairly well but made me drowsy, even half a pill. Weird positive side effect: reduced hot flashes. F 45 2 days

 3  allergies, indoors and outdoors I was on Zyrtec in 2001 before it went OTC. I don't know if it's different being prescribed or OTC, but it worked great on my allergies and I experienced only one side effect: a ravenous appetite! I took it for a year, and somehow I didn't gain weight. I exercised a lot. Feeling like I was starving every minute was horrible. I definitely was eating more to try to satisfy the hunger pains, but it didn't matter how much I ate--I would never feel satisfied. That affected my sleep because I can't fall asleep if I feel hungry. That was such a huge side effect that I asked my doctor to put me on another medication. I've tried all kinds of allergy meds, and Zyrtec did work the second best for me. (Seldane-D was the best by far.) Other allergy meds just don't really do anything for me. But I couldn't be on a medicine with such a terrible side effect, and I'm sure I would've started gaining weight. I had talked to five other people when I was taking Zyrtec, who also took it, and the F 45 12 months

 3  Pet dander/dust mite allergy None Reduced but did not eliminate sneezing and coughing. Worked okay for about two years but now it seems that either my allergies have gotten worse or my body has built up a resistance to it. M 45 3 years

 3  Allergies I came to this website because I have had a dark mood for a few days. I'm not very good at taking medication consistently, but have been a rock star with remembering to take my allergy medicine for about 4 weeks now. I have rarely missed a day and it really helped my allergy symptoms. I was in such a low place yesterday, even having suicidal thoughts. I have cried uncontrollably and not been able to see anything in a positive light. I know everybody has bad days, but none of the things I usually do to brighten my spirits worked, or even interested me. I felt so desperate and it was so pronounced that I don't think it can be reasonably attributed to normal life. I am relieved to hear that other people felt this way on this medication because it gives me hope that is what caused my depression. I wanted to write today because if they are tracking the side effects this dark mood, serious depression and suicidal thoughts are important to note. I did not take today and will not take Knocked out my allergies well. Side effects do not seem to be a fair trade off though. F 45 6 months

 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

 3  Year round Allergies and hives Very tired in the morning after taking it before bed. Feel like I'm in a fog all the time. Drinking alot of coffee just to wake up in the morning. Not sure if the zyrtec or the coffee is causing my stomach gurgling/heartburn(?) Lots more aches and pains than before. Weight gain, water retention in hands and ankles. Eyes burn more than usual and I thought it's supposed to help with that if you have allergies (?) Very very very moody and irritable. Feeling depressed too which is not good. I also take Singulair. Very interesting to hear such similiar complaints. I can't believe that it's all just related to the type of individuals that have impaired immune systems aka have allergies. Some of this must be related to the medicine. I just can't keep feeling like this. Hard to think straight. I am going to go back to Claritin D and see if I notice improvement in any of my symptoms.
