 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.

 1  allergies took zyrtec at about 10:30 in the morning..was at work and started feeling really tired and dizzy. At about 2pm I felt like I had the flu, my throat hurt so bad i couldn't swallow and it was swollen. My fever spiked up to 100.5 (i usually run about 97.9) and it was horrible. I barely slept all night, woke up about every 20 minutes with a jolt. still feeling flu-like the next day. I really hope it gets out of my system soon. I really don't recommend this drug to anyone. I took it once and will never ever take it again. F 23 1 days

 1  I have really bad allergies Depersonalization, mood swings, tiredness, general feeling of being "out of it". I suffer from severe allergies, especially in the spring when all the pollen comes out. I used to take regular Zyrtec a few years ago back when it was available as a prescription and I felt fine. It worked great for me. A few weeks ago I bought some Zyrtec-D and began taking it as directed. One tablet every 24 hours. Within a few days I started feeling moody and I snapped at people that I love over the stupid things. That combined with the tiredness made me think I was coming down with a cold but I never did. I kept taking it and within the last few days I have had severe depersonalization. I feel as though I am watching myself from within. Like I am living without actually living and experiencing life. I stopped taking it yesterday and the feelings have lessened but I can still feel the effects of taking Zyrtec. I would rather sneeze every day than suffer with the terrifying side effects of this drug. M 21 2 weeks

 1  allergies Wanted to sleep all the time, could not stay awake. Felt like brain was in a fog. Dizzy when walking. Side effects are terrible. Yes, it stopped the dripping nose and eyes, but at what cost. It's been over 60 hours since last dose and I'm just now feeling normal again. Will never take this stuff again. F 65 3 days

 1  allergies extreme exhaustion. starving. confusion. mood changes. irritability. LETHARGY. i cannot believe an antihistamine could have this affect on me. i am usually able to overcome any lethargy caused by benadryl, for example, but the exhaustion from zyrtec is disabling. plus i can't think straight. i feel crazy and like nothing is real. maybe this forum isn't even real. i am sad. usually i am happy no matter what. i am annoyed with the universe. i would rather feel ANYTHING than this. i will never take this drug again.

 4  seasonal allergies I've been having the most bizarre, vivid dreams--some quite scary. I've also felt a bit depressed and have been extremely gassy. I figured the dreams might be a result of the zyrtec, but I didn't connect the depression or the gas until I visited this site. I've also had minor irritability, though it would be hard to definitively blame the zyrtec. My seasonal allergies are almost nil. This is the best spring I've had since I moved to Michigan five years ago, and I've been hearing LOTS of people complaining about how bad it is this year. F 41 6 weeks

 1  Seasonal allergies Most severe: Extreme fatigue, extremely severe dizziness, inability to remain asleep, vivid/disturbing dreams. Less severe: Mood swings (sad to angry and back), mild depression, inability to concentrate for long periods. The fatigue and extreme dizziness were the most debilitating side effects. Upon rising from bed, I was so dizzy that I actually fell several times before making the connection to Zyrtec and stopping it. I slept poorly and no amount of sleep would reduce the severe fatigue. Dizziness was worst upon rising, but was persistent to a lesser degree throughout the day. Mood and concentration may have been a side effect of the drug and/or the poor sleep and fatigue. Sadly, it does seem to work better on my allergies than anything else I've taken, but the negative side effects FAR, FAR outweigh its benefits. Symptoms resolved themselves within 2-3 days of stopping the medication. I'll just have to buy tissues and suffer. My nose may run, but at least the room won't be spinning all the time. M 45 45 days

 1  allergies my daughter is 4 and she has been taking zyrtec for about 1 year for allergies, I recently noticed that whenever she would have a "meltdown" it was after getting zyrtec. I began to watch more closely and definitely pinpointed it to the zyrtec. She goes into almost a complete rage and becomes a totally different person. I was referring to it as a pyschotic episode-only way I could explain. Im so glad I found this website because I definitely know its the zyrtec now. It is going in the garbage and I will call her doctor tomorrow and explain and see what else we can try. I just feel bad it took me so long to realize what was causing these episodes. F 34 1 years

 1  allergy symptoms It made me beyond exhausted, and it did the same thing to my boyfriend. For about an entire day, all I wanted to do was sleep. However, I felt tired no matter how much I slept; sleep didn't make me feel rested. While awake, I felt anxious and my ability to concentrate was squashed. Meanwhile, my allergy symptoms were still pretty bad! The medicine only helped a little bit. I'm never taking a medicine with cetirizine hydrochloride again. It felt as if I hadn't slept for days, and couldn't get any relief. I took Target's generic version, but it's the same as Zyrtec and even says to compare the two on the box. F 25 1 days

 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

 4  year round allergies I have not experienced any side effects at all. Also, my six year old started taking this product a few months ago - and she has not experienced any side effects either. I am with the person who posted above in saying that the only people who seem to leave ratings are those with freakishly bizarre side effects. This product has worked well for us (and several friends of ours) for years and nobody I have talked to in person has experienced and side effects from it. :) F 41 4 years

 2  seasonal allergies Restless less syndrome, rapid heartbeat, a sensation of my entire body vibrating, occasional difficulty sleeping, anxiety, tired feeling during the day. I take the tablet at night, just before bed. It did work on the allergies. I had constant post nasal drip from mold and pollen allergies. The drip caused coughing and other typical allergy symptoms. The generic Zyrtec did clear this up quite a bit, not completely. But the side effects are too much to put up with, so I'm quitting the Zyrtec. I'd rather have allergies. F 59 90 days

 1  Asthma Massive appetite increase and gained 14 pounds. Sleepy all the time. I couldn't understand why I was gaining weight all of a sudden and started thinking about what was different and realized that my doctor had added the Zyrtec. I stopped taking it and within 4 days I've lost 10 pounds. F 43 30 days
