 2  Allergies Sleeplessness,Severe skin irritation and weight gain Until I found this web site, I had no idea that Zyrtec could be causing the problems that I was having. I have always had sensitive skin, but lately have been having a rash on my hands and arms that I couldnít get cleared up (skin lesions, general rash). I went to the Dermatologist and he prescribed topical medication for the rash. I used the medication for 4 weeks and wasnít getting any better. Rather than go back to the Dermatologist and get a biopsy (which according to the doctor was the next step) I started investigation the side effects of the prescription medications that I was taking and started eliminating the ones that I didnít absolutely have to take and still no change in my skin irritation. Now I started eliminating the OTC medications that I take. I have been off of Zyrtec for about 4 days now and my skin is finally starting to clear up (YEA!!!). I would have never guessed that Zyrtec could be causing the problem. I have also noticed that in general I am feeling better (better outlook on life, more energy, and clear headed). F 41 2 years

 1  For very bad hayfever I suffered from feeling depressed, extreme anger and at one point lost control and became violent, which frightened my family and me. My wife urged me to come of the drug because she put two and two together as this was not my personality trait. This drug which is also in Pyreteze and many of the one a day allergy tablets. I went to the pharmacist in Sainsbury who looked up side effects in her book and she confirmed that depression was one of them. I would rather suffer from hayfever than ever recommend this dreadful product! M 42 5 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

 1  allergies Dizzy,foggy,"bubble guts"flatulence,nausea,etc,lips felt odd they burnt and tingled,back pain,wired and exhausted at same time. Got zyrtec for seasonal allergies,im not a big pill person maybe once or twice a year I need anything but my face felt like it was going to split from tree pollen so I went to the store and caved on some OTC zyrtec.One measly pill in and I can breathe! Wonderful right? Well yeah and no,breathing is great racking your brain for two hours because you cannot remember the word for banana not so great.All in all im not impressed by the new generation of allergy relief that little blister pack brags about.At least one thing on the little demon pills is correct,it really does last 24 hours.....yay.

 1  Sinuses/Ears Mood swings, depression, extreme fatigue, weakness, dizziness I would not recommend this medication to anyone after just one day I notice I felt angry then after the third day I was in such a horrible mood and so exhausted I would snap at anyone that came near me or looked in my direction. I would wake up and be ok but within an hour of being awake I couldn't hold my eyes open the rest of the day. It's definately not a safe drug to be taking and really should be looked into again as far as warnings and side effects are concerned. F 37 3 days

 1  Seasonal Allergies Strange dreams and thoughts of suicide. Panic attacks and depression. Loss of ability to focus or remember simple daily tasks. Headaches & stomach aches. Extreme paranoia. Facial hives and jaw pain. Dry mouth occurs and libido decreases. At first the medication helps with allergy symptoms but it needs to be regularly taken and after that additional symptoms of panic attacks and depression begin to occur. M 33 8 days

 2  Seasonal allergies Vivid, strange dreams, severe stomach doscomfort, excessive gas. I started taking zyrtec, well generic zyrtec about 10 days ago, after about two days i was having very strange dreams, unlike my normal ones. About 6 days after starting it i was experienceng severe stomach discomfort, no vomitting or dhiarrea, just a sour feeling, along with excessive gas. I didnt really put it all together until i stumbled upon this page, and it was a great help. I started thinking there was something wrong to me, but now it is clear that zyrtec is to blame M 27 10 days

 1  Allergies My son who has seasonal allergies told me about it so I thought I'd get off the Allegra D and give it a try. I take allergy medication year round. At first it was great, but then now after finding this site, I know why I felt the way I did. I am usually an upbeat and happy person, I was crabby, depressed, hungry all the time, could not explain why I gained 20 pounds in 5 months, I was blaming menopause, but the amount of weight gained was ridiculous. Also had blurry vision, didn't have too much trouble sleeping like some people. Anyway after another depressing day of no clothes fitting, I googled Zyrtec and found out about the weight gain issue. Thank goodness, I immediately went off the medication cold turkey. It's been 7 days, I've lost 3 pounds so far without trying, feel like my head is out of a fog, but the worst part is the itching! Unbelievable itching! It just started yesterday and I thought I was going to go crazy, at one point it started at my calves and worked it's way up to my shoulders, very weird. Today so far my palms just itch, hopefully it won't last too long. I'm trying to go without allergy medication to see exactly where I stand since I've been on it so long. F 49 5 months

 1  seasonal allergies shortened sleep cycles, lethargy, irritability, insomnia, disorientation, rapid/irregular heart beat Like many others, seasonal allergies that have never been a real issue before are knocking me out this year. Zyrtec was great for the first couple weeks, then started losing it's effectiveness at night. I will be symptom free for an hour, then suffer allergies for an hour. I skate in and out of sleep, confused and disoriented, and in the morning I never feel like I've gotten any rest. Go through the day like a cranky robot. Now that I know other people are having these problems I am pitching this stuff and making an appointment with an allergist first thing on Monday. F 30 2 months

 1  Allergies Only took it for a couple of weeks on and off, but took it steadily for about a week and became extremely lethargic, I couldn't focus, and I had a definite mood change (and definitely not in a good way). As soon as I stopped taking it I felt a definite improvement in brain activity within a day and felt better overall. I flushing it down the toilet. M 29 6 days

 1  Allergies Sleepiness, being in a dream like state, memory lapses I took one table for severe seasonal allergies and Zyrtec did relieve my congestion however the following morning I overslept, and awoke feeling like I was in a dream. The entire day was a blur and when I came home I was so exhausted I took a nap. This may work for some people but I won't be taking it again. Ever. M 50 1 days

 1  Allergies I have been extremely angry and depressed for the last three days. I also started having flu-like symptoms, so I got on-line looking for Zyrtec side effects because I had just started using the Zyrtec Liquid Gels three days ago. I am very glad I found the comments about Zyrtec causing mood changes. I had no idea that it might be the cause of my sudden anger. I feel very tired and have flu-like body aches. I will report back if my symptoms disappear after I stop the Zyrtec. F 69 3 days

 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
