| 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 10 mg 1X day | 4/19/2010 | 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 10mg 1X day | 4/18/2010 | 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 10 mg 1X day | 4/18/2010 | 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 120 1X day | 4/18/2010 | 5 | allergies | none | so far it works great | M | 49 | 5 days 10 mg 1X day | 4/16/2010 | 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 10 mg 1X day | 4/16/2010 | 1 | allergies | foggy and exhausted | I can't find an allergy medicine that doesn't cause me to want to sleep all day. | F | 36 | 1 days 10 mg 1X day | 4/15/2010 | 1 | Allergies | Mood swings, change in mental state, irrational thinking, dream like states, severe stomach pain, insomnia, crying at the drop of a hat, loss of focus, depression, anger | Don't take this medication. Helps a little with the allergies but rather suffer with the allergies than take this drug again. | F | 19 | 3 weeks 10 mg 1X day | 4/15/2010 | 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 tablet 1X day | 4/15/2010 | 1 | allergies | itching all over my body, developed vaginitis | F | 57 | 3 weeks 30mg 1X day | 4/14/2010 | 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 10mg 1X day | 4/14/2010 | 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 day | 4/13/2010 | 1 | Allergies | Complete change of mental state. | Glad I found this site. Started taking yesterday and have been in a complete bitter state since. This drug may work for some or it wouldn't be so popular but for others... watch out. If you take and your nose clears up but you wish everyone around you would just drop dead and you curse everytime your phone rings... probably not the drug for you. Glad it only took my 24hrs to figure this out instead of the 6 months, year, 2 years it took others on this site. In addition, I have all the other negative side effects listed, increased appitite, sleepy, etc. So it must be an all or nothing proposistion. You either are fine with it and you have no side effects or you have all. Suggestion, buy the 5 pack - take one - if it works great. However, if you notice any of the negative side effects, toss them out and move on. It won't get any better, it will only get worse. | M | 42 | 2 days 10 1X day | 4/13/2010 | 1 | allergies | I took this as well as my 3.5 year old daughter, I took this med. at night and the next day I was so exhausted. Could have slept all day. No energy to do anything. Felt very grumpy, and hungry all day. Couldn't stop eating. My daughter also was very grumpy, hitting things, and hungry all the time that day. I will not take this medication again. My daughter is normally very happy, never hits anything. | F | 33 | 1 days 5mg 1X day | 4/13/2010 | 3 | Seasonal allergies | I took the one pill once a day right before I went to bed, and it definitely relieved all my symptoms and made me feel great. HOWEVER, I noticed that--even though it had been 12 hours or more since taking the pill--I became VERY tired in the afternoon and evening. Like so tired I fell asleep! This is unlike me. | I believe this pill also gave me strange dreams, like even stranger than the ones I normally have. | F | 35 | 5 days 1X day | 4/12/2010 | 1 | allergies | Daughter 3 1/2-- really scarry to see my outgoing child turn into a non expressive sad child! She hasn't taken this for some time, but each time I give it this reaction occurs. Same with singular. | F | 3 | 1/2 tsp 2X day | 4/12/2010 | 1 | Allergies | Hyperactivity, moodiness, argumentative, irrational, loss of focus, headaches | We put my son on this for his allergies 3 weeks ago. He started having some issues in school, but we thought it was because he hadn't been at karate lately. I took him off the med for a week to see if it was really helping, his behavior returned to normal. However, we put him back on it 3 days ago and he had one of his worse days at school ever. I finally realize it wasn't his karate that was the problem (he's been in lessons consistently), but the Zyrtec. I Googled to see about side effects and sure enough, he's had very similar negative experiences. I also took the 20mg dose a couple of times and had two of the worse migraines I have ever had. I have a very high pain tolerance and I was actually afraid I might have an aneurysm, it was that bad. This drug will never be in my home again. I am rating this for my son as it is more important that people know how awful the side effects can be for children. | M | 6.5 | 18 days 10 mg 1X day | 4/12/2010 | 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 day | 4/6/2010 | 3 | Asthama/Severe Allergies | WEIGHT GAIN! About 15-lbs or more? Extreme fatigue, sometimes jittery even though I feel like I can sleep too. Turned into a rip roaring "B" to my boyfriend if I drink alcohol with it! Dryed out nostrils in the morning, stuffiness. | I'm glad to hear that it wasn't my imagination about the Zyrtec causing the weight gain. I can't win...I suffer from allergies/asthma or gain weight and don't suffer. Wonderful. | F | 44 | 4 months 5 MG 1X day | 4/6/2010 | 1 | My 6 yr old son had severe behavioral changes within 24 hrs of taking this drug. He was getting bad behavior reports from school that week. He was depressed, cried over little things, had angry tantrums, was violent,incontinence, sleep disruption and falls from the bed. The only change in his routine was the medicine. I remembered the pharmacist saying it differes from claritin in that it works using the central nervous system (we were not getting any results from claritin). I put the pieces together and took him off the drug and already 24 hrs later he is almost back to normal. This is not for every kid - watch their behavior closely if you try the drug. The label does warn of "mental or mood changes." | M | 6 | 10 days 1X day | 4/6/2010 |
