 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

 3   Bad sore throat, Earache in one ear, headache, mussell pain in neck and in back and shoulders, arms,felt really strange and had a hard time thinking straight. This drug works for allergies but causes great discomfort in the body as a whole. Nothing helps much so u suffer with the side effects for many hours after taking it. I have taken this drug off and on for many years each time having to stop taking it because of the bad side effects. Today i had enough and I took my bottle of Zyrtec and I flushed it down the Toilet!! F 49 7 days

 3  Year Round Allergies/Asthma My son has several allergies, eczema, chronic sinusitis, and asthma. I know that the Zyrtec helps his itchy eyes, itchy throat, and helps control his sneezing. My 7 year old son has been taking Zyrtec for years for his allergies. He takes one tablet with breakfast and also takes two puffs QVAR (steroid inhaler). It wasn't until reading all these posts that I realized that so many of his behaviorial problems are more than likely side effects. He has horrible angry outburst, hard to get him up for school, will say he hates himself and that he's stupid. Has a hard time focusing in school. His teacher and I assumed he is exhibiting ADD symptoms. I even researched ADD diets and was loosly treating him as if he had ADD. I do notice he scratches a lot - but he also has eczema. I will definatley start weaning him off. He will need another medication to control all his allergies though. He's been on Nasonex and some other med when he was little(about 3yrs old) that gave him night terrors and sleep walking. Poor kid has gone through so much - but never complains. M 7 3 years

 1  hay fever Depression: feelings of hopelessness, helplessness, despair. When I stopped taking this medicine, within two days I felt as if a great dark cloud had lifted and i was myself again. I will never, never take this medicine again. I will never allow my children to take it. I very nearly made some serious changes to my family because of what I thought were reasonable feelings; if I hadn't made the connection between my hopeless feelings and the medicine I was taking, I would likely have wrecked my and my children's peaceful home life.

 1  Year round allergies I have taken generic Tavist for many years. It became hard to find and I thought I'd try the newer wonder drug, Zyrtec. I took 1 pill last night, along with other meds I normally take. I've been extremely drowsy all day. It isn't wearing off. I will not take it again. I thought this was one that did not (generally) cause drowsiness. For me it is currently debilitating. I am waiting for it to wear off after 20 hours the drowsiness is increasing if anything. I napped this afternoon! I don't plan to try this again. I have taken antihistamines my whole life but rarely been this drowsy from any of them. Oh, it worked - no allergies today - but it's not worth it. I'm afraid to try again, although might try the lower dose at some point. F 62 1 days

 4  Allergies and sinusitus The only possible side effect I've noticed is dry nose. This is irritating and sometimes painful. I've taken Zyrtec year round for years. I still need occasional decongestants when the pollen is bad, but overall, it works pretty well. I sleep great and have a very level mood and am a happy person. I never realized how great this stuff was until I tried switching to Allegra this week. Compared to Allegra's side effects, Zyrtec's are nil. Thanks Zyrtec!! F 43 3 years

 1  seasonal allergies Vivid, strange dreams, unable to wake up all of next day, dizzy, jumbled thoughts, afraid to drive in this condition Totally disfuctional today. I am not usually over reactive to any drugs. I am on an anti-depressent (in case that info helps someone see a pattern and/or protect others or themselves). I tried this today because Claratin didn't do anything for me last season. F 47 1 days

 4  Severe allergies At 10 mg taken at bedtime this was the most effective antihistamine I ever tried - and I tried many! But the tradeoff was a nasty Benadryl-like hangover upon awakening and until after lunch. I then tried 5 mg at bedtime and could not believe the difference. My allergy symptoms indeed crept back a bit, as in occasional sneezing or itchy eyes, but the improvement in mental state was huge and definitely worth it. I now use some backup treatments when needed, like Nasonex, Nasalcrom, and even butterbur. All those miserable with 10 mg - do yourselves a favor and reduce the dose to see what happens. M 51 1 years

 3  Seasonal Allergies Stabbing headaches, drowsiness, stiffness in upper back and unable to get a good sleep. I've been using Claritin for the past few years and decided to try Zyrtec for the first time this season. I don't like to take any meds unless I absolutely have to. It took a few hours for the meds to start working. It made me drowsy which is not unusual when you take any medications. For me it's always good to take the medication, wait and rest for it to start working. It worked okay for the most part, my nose stopped running and I stopped sneezing. One of the side effects is that I wake up with a dry nose and it's just a tad stuffed, but goes away. I took one pill on Saturday afternoon, by Sunday afternoon the medication should have started to wane, and I wasn't planning on taking another one. The side effect was that I started getting stabbing headaches that lasted for almost 24 hours. I'm not sure if it was the Zyrtec. So on Wednesday my allergies came back and I took another pill that afternoon. After 24 hours again, the next day, I started getting the stabbing headaches. Coincidence or side effect? I'm not sure if I want to tempt fate again, but I think....maybe I do it one more time, just to be sure. But not yet...I think I'll hold off...these headaches really hurt. F 47 2 days

 2  allergies some drowsiness, dry eyes. Upon withdrawal the feeling of itching and pain in the eyes developed and has persisted for several days so far. It feels like there is something in the eyes yet eye exam shows nothing. Not sure it is from zyrtec withdrawal but there seems to be no other explination. would not use it again for allergies. M 60

 2  seasonal/occupational allergies i started out taking one zyrtec/day. at first they made me incredibly sleepy and i took afternoon naps if i could. also, i'd get a bad headache that would pound with my heart beat, have nightmares, and not be able to sleep soundly at all. slowly, even after i decreased the dose from 1 to a 1/2 of a pill per day (to avoid the exhaustion/drowsiness and general "weird" feeling), i noticed myself feeling more disassociative and depressed. i started seriously contemplating suicide, and the detached thoughts about wanting to die increased with every day i took it, as though it was building up in my system like a poisonous depression in a pill. yeah, my allergies were completely gone, which was relieving, but what's the use of living without allergies if all you can do is cry, feel generally irritated with life, and want to die after taking an allergy pill? weird to feel so indifferent, almost enthusiastic, about the idea of dying...never really felt that until i started taking zyrtec...the 1/4 of a pill dosage seems to be most manageable for me, but even at that dose, i can't handle it for long periods of time...every few days i have to stop taking it to avoid the highly negative side effects, as the medicine builds up in my system. also, crazy heart beat (even at 1/4 pill) if i'm doing anything that involves physical exertion. thankfully, for me, 1/4 of a pill somehow keeps my asthma, itchy eyes, sneezing, etc at bay with way less exaggerated side-effects than a 1/2 or a whole pill seem to cause.

 1  Seasonal allergies Severe lethargy, depression, a numb feeling inside and out. No emotion, inability to make decisions, a feeling of despair, foggy brain, constipation, confusion. Works for my allergies but not worth the horrible feeling that comes with it. F 52 7 days

 4  hives in the beginning, extreme drowziness, but the more I take it, the less fatigued I feel. I take it for hives, which I've had lately for over two months, cause unknown. I also take Singulair in the morning. I have noticed I am more hungry than usual, and do experience bizarre dreams. I don't think this drug causes aggitation. The aggitation is from not knowing what causes the hives, which have come and gone for the past 6 years. I think it may be hormonal. They appear in the evening and are gone by noon. Also includes some episodes of angioedema. More hot flashes than usual, but again, can't blame this on the zyrtec. F 61 3 weeks
