| 2 | Seasonal Rhinitis | Vivid, emotional dreams. Dissociation. Fatigue. Altered thinking. It has been very strange. I'd wake up at night very scared. I'd wake up and think I was losing my mind. Hard to get along with my family while on this - I'm married with 4 kids, so not a great side effect. Great for allergies, no doubt, I'm just not eager to start all the psychiatric medications I'm going to need for the side effects. | This is a very weird drug. I thought I was I was becoming mentally ill until I found this site. I think I'll save it for only the worst outbreaks of ragweed allergy and take my licks in the meantime. Nothing else seems to work. | M | 34 | 1 weeks | 6/5/2006 | 2 | sinusitis and skin allergies | weight gain, tendinitis, plantar fasciitis, depression, mood swings, lack of motivation | I developed "skin allergies" while living in Japan. during that year, I was infested with scabies (twice) and developed hives and skin allergies as an after-effect.(???) One month before returning to the USA, i was prescribed zyrtec for my allergies and it provided great relief. When I first began the drug, I weighed 183 lbs. Within a month (and with riding 200 plus miles a week, running 25 plus miles a week, and swimming 20,000 yards a week) I gained 10 pounds. About 6 months later, I developed plantar fasciitis in my left foot, which impacted my ability to run. Within another 6 months, I gained 5 more pounds and I developed plantar fasciitis in my other foot as well. My elbows also became sore and I experienced increased muscle fatigue and cramping. . I am still on the medicine and my weight is up at 210 pounds with no real changes in diet and only a slight decrease in physical activity. (12+ hours of cardio each week). I have now suffered from plantar fasciitis for 2 year | M | 34 | 3 years | 2/27/2008 | 2 | allergies - severe sinus | mood swings, irritability, frustration and anger, painful swelling in neck, lethargia, heaviness of limbs and difficulty moving, insomnia | the side effects were very noticible to others. my boyfriend was very concerned about me and begged me to stop taking it. | F | 34 | 1 days | 3/18/2008 | 2 | eye allergies | I am so ridiculously happy that I found this forum. I have been hanging out with friends and should be having a blast considering the weekend but found myself not having fun as things progressed. I have had unexplained depression, definite anxiety, bizarre dreams, and mild panic attacks. I am certainly not feeling like myself at the moment. It's been bad enough that I've pondered asking for anti-anxiety drugs from my doctor. I started suspecting a problem with the medicine last night as I had a panic attack within 15 minutes of taking it. I'm not one to ever have a panic attack under any situation. Looking back, these problems started and have continued to get worse since being on the drug. | Other than the obvious problems which will keep me from ever taking the drug again, it did seem to help my eyes. | M | 34 | 2 weeks 10 mg 1X day | 3/21/2011 | 2 | dander and seasonal allergies | It makes me lethargic and VERY moody/stressed. It also increases my appetite. When i take Zyrtec, I feel very disconnected and impatient. Very unlike my usual self! My daughter (age 5) takes it for cats, too, and is like a zombie all day. I don't like giving it to her unless absolutely necessary. | I will not take it anymore unless I am going to visit a house with cats. It works great for reducing my (very severe) asthma symptoms when exposed to animal dander (no other med. works for that at all). I keep it just for emergencies. | F | 34 | 2 weeks | 1/18/2006 | 1 | allergies, sneezing | I have been on zyrtec for about 3 years and have been unable to quit because every miss just one dosage, I get horrible migrains and nausea where I can not even get out of bed. These migrains last for as long as I do not take the zyrtec. I also have hair loss and have become more alergic to things that I was not before. I have also had panic attacks that may be related to the zyrtec. | Does anyone have any suggestions on how to quit this stuff? Please stay away from this drug!! | F | 34 | 3 years | 3/22/2006 | 1 | Allergies | Upset Stomach all the time. Tremendous appetite Very Sleepy all day even when taking it at nite. Slept great but could have slept all day. | M | 34 | 10 days | 2/2/2006 | 1 | Allergy/Runny Nose | Hives and aggressive mood, lots of biting. | My son started taking this stuff when he was 16 months old and with in 2 weeks of taking it I noticed him biting a lot more. The people at his day care said he was extremely aggressive to the other children. Now lately he has had hives. He is now 19 months and still has the runny nose. This medicine is not good. | M | 34 | 90 days | 1/24/2007 | 1 | Cat allergies | Sudden asthma attacks. No history of asthma. Constant sinus congestion. Tired, run down, feeling withdrawn and no desire to participate in outdoor activities I used to love. Irritable, mood swings, and general malaise. | I started taking Zyrtec (begrudingly, as I hate taking ANY medication) to control cat allergies. Only take it when symptoms begin to show which is about 1/2 pill 2-3 times or less per week. About 2 months ago I began having sporadic asthma attacks, usually at night, lasting for anywhere from 30 minutes to several hours and occasionally wake up in the morning with asthma symptoms persisting. Now I'm getting asthma attacks during physical exertion (I'm an avid hiker) and can no longer enjoy this activity because it's so taxing. This is why I hate medication. Going off it and never taking anything again!! | F | 34 | 3 months 5mg 2X W | 10/28/2011 | 1 | Allergies | Constant headache and extreme drowsiness. | I took zyrtec at night the first time and by morning I woke up with headache. I have been extra sleepy and need more sleep then I ever had. I didn't think that it could have affected me so quickly but it is the only medicinal change that I have made. The improvement to my allergies is not worth the headache (that doesn't go away with pain medicine) or extreme sleepiness. Hope this helps others who are struggling with headache side affects as main source of frustration. | F | 34 | 4 days 10 mg 1X day | 3/16/2011 | 1 | Allergies | Sleepy but I couldn't stay asleep for very long. Once I woke up I felt really weird. I felt like I was gonna have a panic attack or cry. A few hours latter I was sweating a lot and I became very cold. I also felt disoriented. Later that night I became very sick and thought I might even have to go to the hospital. It's two days latter and I'm still under the weather just not as sick. If I had taken any more whose to say I wouldn't have been dead. | I only took one I didn't need another one to increase the negative side effects. I had to go to work the day I took it for the first time only to find out several people had similar side effects. Also only to find out they were still taking it but said they took it at night. This is not candy if you are experiencing these type of side effects don't play Russian roulette stop taking it. I would never recommend taking this pill there are other pills on the market or you could get allergy shots. | F | 34 | 1 days 10 mg 1X day | 5/9/2010 | 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 2.5 ml 1X day | 5/18/2010 | 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. | F | 34 | 1 days 10mg 1X day | 4/19/2010 | 1 | Allergies to pollen, dust and mold | I have taken Zyrtec in years past with no side effects. HOWEVER, I went back on it 5 days ago after taking Allegra for 3 months and having bone pain with that, and I am so sick, I cannot believe this is the same Zyrtec I used to take. They must have changed the formula. I am so tired and lethargic, it feels like an effort to breath. I have to drink something with caffeine just to stay awake. I have almost no appetite, can't eat more than a few bites without feeling sick. I have alternating constipation and diarrhea with severe gas. I have not taken a dose of Zyrtec today and I will never take it again. I cannot wait until this garbage is out of my system and I feel human again. I would rather just suffer with the allergies for the rest of my life. | DO NOT TAKE IT! YOU WILL REGRET IT! | F | 34 | 4 days | 7/22/2007 | 1 | Allergies | Heart palpitations and arrhythmia (bigeminy) | I felt great when I had been on Zyrtec for a few weeks, but then I started having heart palpitations/fluttering, and sometimes my heart felt like it was going to pound right out of my chest. Every day it got worse, so I went back to the doctor and she found I was in bigeminy (arrhythmia). She referred me to a cardiologist and an endocrinologist, and all their tests came back A-OK. After six weeks I was so fatigued that I could barely work, and at that point I started my own research online. I found a few accounts similar to my own, and I took myself off the Zyrtec. The heart palpitations started decreasing in 2 days and in a few weeks they were gone. Goodbye Zyrtec! | F | 34 | 6 weeks | 12/4/2006 | 1 | seasonal allergies | tiredness, irratible, itching | I have been on this medicine for about 5 days. I have been wiped out but assumed it was a spring cold. I basically slept all weekend and was so exhausted that I was incapable of caring for my three young children. I feel like I am in a fog. I have also have zero patience with my husband or children for the past several days. Then, the itching on my face started! It was only when I read this site that I realized my extreme overtiredness and irratibility may be caused by this medication as well. The face itching is unbearable and I am going to stop immediately. I just hope I can get this out of my system quickly! | F | 34 | 5 days | 5/2/2005 | 1 | Allergies, facial hives | Increased appetite and weight gain | I started Zyrtec because I was getting hives, a new occurrence for me. At first I was very happy; I have no noticeable behavioral side effects - no fatigue, dry mouth, or any of the effects listed on the prescription bottle or here on this forum - my goodness, this sounds like a bad drug for some people! It is the only drug that has helped with my hives; Allegra-D gave me headaches, and OTC medicines didn't work. However, I have been eating like a horse, and have gained 5-7 lbs. in about a month. I missed my dose one day and did not have any adverse effects; I'm going to try going off Zyrtec and see if my hives stay away and if I can drop the weight. | F | 34 | 2 months | 4/13/2005 | 1 | seasonal allergies | Severe nightmares | It took 3 nights of severe nightmares and waking up crying, and unable to stop for an hour, to realize it was Zyrtec. | F | 34 | 3 days | 12/18/2008 | 1 | Seasonal allergies | weight gain, depression, irritability, feeling in a fog, lack of focus, exhaustion, hand and feet tingling ect. ect. | I started zyrtec for my seasonal allergies, I just returned today from the doctors office because I thought I was severely depressed even though I had no history. As I was surfing for information on the SSRI I was prescribed I came across this and realized I had the same symptoms as other from taking this medication. I have missed doses in the past and would wake up in the middle of the night itching and grabbing the bottle. In eight weeks I have gained 10 pounds and truthfully I have an amazing diet, not to mention I am an avid runner but in the past few weeks I lacked the energy to go out and do it, to tired or depressed. I would avoid this medication if at all possible! | M | 34 | 8 weeks | 6/23/2008 | 1 | hayfever | Highly oppositional attitude, suicidal thoughts for the first time in my life, rapid-onset tinnitus | Behavioral changes took effect within an hour of a single dose. I tried dumping my partner of three years for "always trying to pick fights". I gave up my ipod and stopped listening to music in the car thinking I was blowing my eardrums out--Turns out it was zyrtec. I did not take a dose every day but cycled on and off over the course of five months in response to seasonal pollen. At the time I was taking the drug I had a 200mg/day caffeine habit going on. I'm unsure how they interact as I quit Zyrtec before I quit caffeine. | M | 34 | 5 months | 6/23/2009 |
