| 3 | Year round allergies | Unexplained drowsiness, need for caffeine, unfocused, dispirited, easily prone to confrontations with loved ones, bouts of depression | I started back as a cashier with a grocery store about 2 1/2 months ago- everything has been great but one of the things we are measured on is how quickly you ring the customers through your line. I was at the bottom of the heap since the start. Just this week I STOPPED taking zyrtec and instantly I have jumped to being the middle of the pack, on my way to being way above average. And drinking LESS caffeine at work also. Yes, it had to be the zyrtec, thank goodness I figured that out! | M | 47 | 6 months | 6/26/2009 | 1 | Allergies | Severe mood swings, anxiety, sleeping more but never feeling rested,apathy, depression, no desire to do anything, excessive gas (bloating/flatulence), increased appetite, weight gain. | I just began having allergies last year. I was taking Sudafed or Advil Sinus(as needed) but still having sinus/allergy problems. Doctor suggested I try Zyrtec - taken on a daily basis. It worked GREAT for my allergies. Unfortunately, it began to be terrible for my outlook on life. I didn't know what was happening to me. I have stopped taking this medication. Within two days of not taking this stuff, the depression, apathy, gas and increased appetite I was experiencing disappeared. I have energy again. It feels like I have crawled out of a dark pit. I didn't even realize how bad the depression was. It's been five days without this medicine now. I've had mild nausea, dizziness and insomnia but all are fading with each day. The weird thing was the itching that began on day three. I have never had hives or itching before. This is not a symptom of my allergies returning for me...this is a withdrawal. I will NEVER TAKE THIS MEDICINE AGAIN! I'll deal with my allergies some other way. | F | 48 | 60 days | 6/23/2009 | 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 | 1 | allergies | Have had no problems with zyrtec 5mg but have noticed the 10mg/24 hour dose gives me a horrible headache. | Just wondering if anyone else has noticed that 5mg works fine but the 10mg dose causes problems. It's just like the medical industry to have the view that if one dose works well twice as much is even better! Maybe some of the folks here who've had problems would try 5mg instead of the 10mg they'd be happy with the results. | F | 41 | | 6/21/2009 | 2 | Cold-like symptoms | Cottonmouth, dehydration | I took a single dose in the evening, and kept waking up every couple hours during the night with a mouth like a desert. It was like it turned off my salivary glands or something. It may work for you, but this was a problem for me. | F | 23 | 1 days | 6/18/2009 | 1 | Cat allergy | Extreme dizzy/spaced-out feeling, fatigued but unable to sleep, irritability, trouble focusing | I've taken Zyrtec occasionally over the past few years, but I recently got a kitten which has made my allergies act up, so I have taken Zyrtec everyday for the past 3 weeks. Throughout this time, I've felt OK, a little tired/spaced out, unable to stay asleep, but I attributed all of that to lack of sleep. However, I didn't take the med for about 3 days, and felt fine. Then, I started it up again, and ever since, I have had the terrible symptoms I described. I feel like my state of consciousness is totally altered. I'm completely spaced-out. You know feeling when you stand up to quickly after lying down? I'm experiencing that same feeling constantly for 3 days now. Yesterday I stopped taking the Zyrtec, and hopefully I will have my brain back. | F | 21 | 14 days | 6/18/2009 | 1 | Allergies | My 6 year old son changed into a completely different little boy. His allergies cleared up but he showed signs of aggression,anger,and sadness. | Once I found out his behavior at school had drastically changed I was determined to figure out the cause. Then I realized it all began when he started on Zyrtec. I am so thankful for this site because I realized my son wasn't the only one experiencing these side effects. Now he is back on Claritin which isn't as effective as Zyrtec in clearing up his allergies, but I don't have to worry about crazy side effects. If you plan on giving your child Zyrtec, please keep a close eye on them for any changes. | M | 6 | 20 days | 6/15/2009 | 5 | Various allergies | None | I am happy using this drug. With other antihistamines I have experienced side effects, but Zyrtec works fine for me and relieves symptoms relating to food and air born allergies. | M | 47 | 3 years | 6/14/2009 | 2 | Severe Allergies | Didn't want to wake up in the morning, drained all day till about evening time, moody, depressed, hair falling out, | I stopped taking Zyrtec and now I can't sleep through out the night, and I find myself anxious | F | 31 | 2 days | 6/14/2009 | 2 | allergies | okay this is really weird but i had been taking zyrtec for about a week and it helped my allergies but i noticed when i stopped taking it about 10 days ago i got really bad anxiety, heart racing, emotional, trouble breaathing, chills i dont know if this has anything to do with not taking after i had been on it for a week but these might be bad side effects im not sure yet but it is very scary so im going to the doctor about it in a few days but if this has happend to anyone else please comment back. | F | 16 | 7 days | 6/13/2009 | 1 | Allergies | I got very dry skin and a red scaling rash on my elbows. It made me so tired I couldn't concentrate at all and could barely keep my eyes open, yet I could not sleep. Started to get asthma again, also. | I have a lot of allergies and have been going through various treatments for a long time. Zyrtec was pretty good at masking my sinus problems. But I was so wiped out by it, I think its worse than Benadryl. And my problems came back right away when I went off it. Which isn't always the case with Benadryl. I'm sensitive to drugs. The positive side of Benadryl, if there is one, is you can by the 4-hour caplets and break them in half. Then you take it at night and it wears off by the next day. I dislike any time-release drug because of the potential for it to make me unable to sleep. | F | 42 | 15 days | 6/13/2009 | 1 | allergy control and sleep aid | Was suggested I try a similar product after taking one benadryl a night for about 2 years. It was suggested to help aid skin irritation and sinus.Benadryl left me feeling a little groggy but workable. I took one 10mg Zyrtec at night. I was frustrated it didn't help all that much, I was surprised I felt more groggy for what I was told is not as strong of a medicine as benadryl. I didn't connect things until I decided to stop taking it about a week ago. I had become noticeably more sad and I was gaining weight and no longer up to working out. I was shocked I noticed the sadness went away that had been building and I dropped a pound, water weight likely almost immediately. I didn't connect any of this then and suddenly realized it had to be the Zyrtec, only new thing I had added to my system. I got online and saw many have had similar reactions. Thank goodness people have written about their experiences. I do NOT recommend Zyrtec. Not for sleep and nor for allergies which at lea | I did not connect the itchiness until I read others comments! Thank you for sharing,I was frustrated with why my skin was itching even worse than before the Zyrtec! And I had only been taking it maybe 6 months! | F | 48 | 6 months | 6/13/2009 | 5 | allergies | I don't believe there's been any - sleeping rather hard, dreaming alot. | Never had any allergy issues until this past winter - tried Claritin and others - Zyrtec did the trick, if I stop taking it, I start right back up with the symptoms - looks like a long term thing for me. So far, no issues that I can tell. | M | 49 | 9 months | 6/12/2009 | 2 | allergy cough that is always there | With-in an hour I felt morbidly depressed and hopeless. I thought it was my imagination. But I had the same outcome for the entire 5 dose package about 10-40 minutes after taking it. After I stopped, this completely stopped! Then my left eye started acting weird-like spots that come and go. | It did help the cough. One of the only things that ever has.. But now I am spooked about taking it. I wonder if this medication has any impact on eyes (retina/ response to bright light) or if that has been considered? My eye is still not right. I see a DR Friday. Kind of scary-these drugs with their harmless happy-go-lucky candy store advertising. | F | 48 | 5 days | 6/10/2009 | 2 | allergic reaction, seasonal allergi | depression, mood swings, disturbed sleep, apathy, very wierd dreams, weight gain, memory loss | not really sure what made me wake up yesterday and say I'm not taking that any more--the difference in just one day is scary enough that today I went looking for side effects for Zyrtec--I agree with the others-I'd rather have a stuffy nose than feel like this anymore | F | 49 | 3 months | 6/9/2009 | 1 | My son was taking it for allergies | Severe temper tantrums (multiple times per day), head banging, sleeplessness. | My pediatrician recommended Zyrtec for my 2 1/2 year old's allergy problems. Before he started taking it, the only real problem we had was his sleeping. He was getting maybe 5 hours/night because of his allergies. After he was on it for a week or so, he became violently aggressive. We had not had too much of a problem with hitting or kicking before this. He also began banging his head during his tantrums and wound up with several bruises. Anything could, and would, set him off. He also stopped napping, which made him even more tired and irritable. I just stopped giving it to him, and hopefully we will see a change. | F | 27 | 7 days | 6/8/2009 | 1 | My son | His behavior gradually became very agressive. He was having sleep issues, anger problems and would cry very easily. He mentioned that he could not control it. I have stopped using the medication and I his behavior has returned to normal. It was so bad at one point that we were going to start him in therapy. Now I do not see the need for that. | M | 5 | 4 months | 6/7/2009 | 1 | seasonal allergies | moodiness,aggressive behavior,sleeplessness,irratable, inability to concentrate,rash on the back of neck | My son has not been himself for three weeks, he has been so irritable, angry and aggressive. He has had difficulty sleeping and has had some very serious problems in school with friends and his schoolwork. I only wish I had thought about a possible connection with Zyrtec. Today is the first day I did not give him any and I am hopeful I will notice a difference soon, I will never give him Zyrtec again, I will look into alternatives. | M | 6 | 3 weeks | 6/5/2009 | 3 | Seasonal Allergies | I started giving my 3 yr. old Zyrtec 8 days ago. It seems to be helping the stuffy nose and itchy eyes. Two days after starting the meds., She started having accidents. She has been fully potty-trained for a whole year- no accidents. Now she has 3-4 a day. She tells me she just can't tell when she has to go anymore. | F | 3 | 8 days | 6/4/2009 | 1 | allergies | I noticed after the second time I took zyrtec that i had some itching on my chest and when I looked in the mirror it was bright red. The next morning I was pink all over and had splotchy pink areas on my stomach. I took some Benadryl in hopes of counteracting an allergic reaction. It helped some. Allergic reaction? | The first night I took it I noticed my body was a little pink all over. The second time I took it a couple of days apart I also noticed after getting about 2 hours of sleep that I was wide awake and couldn't fall back to sleep and had almost like racing repetitive thoughts. Strange. I may try to mimic this response with another trial but I have a feeling this may not work out for me. | F | 36 | 2 days | 6/4/2009 |
