| 2 | Seasonal allergies | Tired, decreased energy. | F | 15 | 3 weeks | 6/5/2012 | 1 | Seasonal Allergies while hiking | I just started suffering from a non stop runny nose while hiking in the local mountains. I first tried Clariton which stopped the runny nose but I noticed I felt wobbly while hiking at altitude which is not safe so I tried Zytek hoping for and improvement. Not only was the 24 hour pill WORSE it could have killed me. I was leading a hike up a mountain I had conquered many times before and the Zytek made me nauseous, severely weak, tachcardic AND dizzy. I was unable to finish the hike on a very hot day and risked dying going by myself to the car. Even the down hill was an extreme challenge. It is going in the trash! | F | 44 | 1 days 10 mg 1X day | 6/2/2012 | 1 | Allergies | It works but the side effect that never goes away for me is the fatigue. I've tried taking it at night. I still cant get the sleepiness to go away. I feel drugged.... | F | 41 | 2 months 10 MG 1X day | 5/31/2012 | 1 | Allergy To Bug Bites | My normal cheerful mood changed so much that my friends and family commented on the change. Almost everything made me mad! I had loss of appetite and nausea and in general, just felt bad. I couldn't really attest that it helped with my bug bite reaction either. I normally walk a mile a day and don't have any real aches and pains but my knee joint started hurting two days ago and after doing some research on Zertec I will never take this again. I have almost returned to my normal self, hopefully I didn't take it too long. | This product is just not worth the side effects to me. | F | 65 | 14 days 10mg 1X day | 5/30/2012 | 2 | allergies | easily angered, angry, near violently angry - I'm an old woman who likes people and I said MF... the swear word... for the first time in my life and then I sulked because I knew they didn't hear me... crazy mood swing... sleepiness and foggy brain (could be allergies), and piercing headache to forehead... I thought I was stroking out... | fortunately this is fourth time I've experienced a medication induced personality change/reaction.. I stopped the zyrtec immediately. I started on zyrtec because claritin ( 9 years of seasonal use) seemed to fail... something that happened with a previous med that I used seasonally for years. At the pharmacy, I asked for suggestions and was told to try zyrtec. It immediately did relieve my allergy reactions... which was nice... but the side effects were horrendous. Luckily for me, over the many years I have taken meds and did diets, I have had adverse reactions and knew after I thought about it ... that my personality change... extreme anger, vocal expressions of annoyance, and depression... was not ME. I am stun by my inability to control angry impulses over the last two days I took zyrtec. I only recognized the problem about 4 hours before I was goin' to take my next 24 hour pill. I was taking a over-the-counter dose.,,10 mg. and my adverse reactions started on the second day... I only used it for three days total. I'm goin' to be sure to include zyrtec on my med allergies | 64 | 3 days 10 mg 1X day | 5/22/2012 | 1 | Allergies | When I decided to discontinue taking Zyrtec, I experienced unbearable, continuous, incapacitating itchiness. My entire body was covered was covered with large welts and even loose clothing caused painful hives to erupt . There are no words to describe the suffering involved. I took cool showers and used cortisone ointment to no avail. I finally had to start taking Zyrtec again to stop the suffering, which was acute. | I called the manufacturer of Zyrtec for advice on how to get off the drug, but the representatives I spoke to on two occasions said they had never heard of any side effects from quitting the drug. In the meantime, I'd checked the Internet for information about Zyrtec withdrawal symptoms, and there were literally thousands of comments from other people who had suffered incapacitating itching when they they tried to discontinue---some after taking the drug for only a short period of time. Without any guidance from the manufacturer, I reduced the amount of the medication very gradually from three-quarters of a pill, to half. This took me about two years to accomplish. Now, three years later, I'm down to one-quarter of a tablet once a day. It has taken that long to almost get my system rebalanced! I hope I can get off this drug completely. I think it's criminal that there aren't warnings about discontinuing this medication Worst of all, I was offended and angered by the arrogance of the manufacturer who said through their representatives that they'd "never heard" of anyone suffering from discontinuing the drug. Apparently, most doctors have also been misled about Zyrtec and believe it's benign. Buyer beware. | F | 68 | 9 years 10 mg 1X day | 5/21/2012 | 3 | allergies | Everytime I take zyrtec, I get a weird pain in my right lung area. I'm convinced it's the zyrtec, because it's never happened before until I took it. | F | 15 | 1 days 10 mg | 5/17/2012 | 1 | Seasonal allergies | Anger, fatigue, emotional outbursts including crying and yelling, clothes and hair bothering her, stomachache. My daughter has taken Zyrtec (generic) as needed for a couple of years. This time around, she had been on it for about a wk or so but still complained about her allergies. We also noticed her fatigue and thought that she might have a virus but we kept her on the drug. I even slightly increased the dosage this wk (per her doctor's orders) and split it so she took some in the AM and some in the PM but she still was complaining about not feeling well. This wk she has been very emotional over minor things and started to complain about her stomach hurting. Then, she said, "I am mad but don't know why." Later, she said she went to her room and felt like throwing all of her stuffed animals off of her bed, but didn't have any explanation as to why she would want to do so... | She is normally a very laid back and go-with-the-flow type of child so this was concerning. She even said that her heart was beating very fast. I quickly took her off Zyrtec & called her doctor, who simply suggested a different drug because of the fatigue & didn't acknowledge the behavior issues. Last night, after being off of Zyrtec for almost 24 hrs, she said she didn't feel well & she didn't know why, thought her heart was racing & asked if she could go to the doctor in the AM. That was it. We immediately went to the ER of the local children's hospital where she had an EKG that was normal. The doctor there said he sees this problem all the time with antihistamines in children. He stated that some children just go off the wall crazy with them & that it would take a few days for her to return to normal & that if she wasn't better by then to see her dr. That night was horrible & it was almost midnight before she could calm down enough to sleep. Her clothes were bothering her & she was worried about everything. Tonight will be 48 hours w/no meds & she seems to be doing better today w/only one small crying incident about her hair, one time where she said her pants made her feel bad (angry) & one time she said she was mad at her sister & blamed the meds. (LOL) I just want my girl back. I hope this helps someone else. | F | 7 | 3 weeks 1X day | 5/12/2012 | 3 | Constant runny nose, allergies | Doc recommended Zyrtec after a combination ear infection and sinus infection, so I started taking it every day. Been dealing with some really bad anxiety, depression, and constant fatigue and lack of motivation.... Ran out of my pills one day and got lazy about taking more, so I just stopped. Slept like crap for a week (withdrawl?) but suddenly realized I wasn't NEARLY as tired as I used to be, and have a bit more motivation to do things now. I'm convinced it was the Zyrtec. | Worked great for my allergy issues, but it's not worth it feeling like a worthless zombie EVERY SINGLE MORNING. | F | 30 | 2 years 1X day | 5/2/2012 | 2 | Hay Fever | frequent nervousness, trouble sleeping. | Not very good | M | 12 | 3 years 1X day | 4/30/2012 | 3 | Severe allergies,indoor/outdoor | Severe vaginal dryness with cracking and bleeding of skin with bumpy rash in and around the pubic hair. Ear infection and itchiness of the ears. | I am posting this side effect because it is NOT listed with the other side effects that people are posting. I have noticed weight gain as well. The reality is that I already had trouble with my vaginal area and I believe this drug increased and caused new issues. I have not had a sinus or ear infection in about two years, developed an infection in both ears which has lasted for about two weeks, ears are severely plugged and I have been woken up the last two nights with extreme itching in my right ear and much itchy discomfort in the vaginal area. | F | 37 | 4 months 10mg 1X day | 4/28/2012 | 5 | allergic asthma, hay fever, asthma | dry mouth | Zyrtec has made my asthma much easier to deal with, with other medications added, such as singulair and a steroidal QVAR inhaler daily, my allergic asthma is much more controlled. The lung specialist I was seeing wanted to place me on Xolair injections for severe, uncontrolled asthma, when I learned there was a slight chance of anaphylactic shock and cancer in clinical trials, I decided against the injectable. While taking the Zyrtec I am now able to have my 2 dogs in the house and love on them without breaking into hives, as well as eat some foods, which I use to react badly to. | F | 40 | 2 years 10 mg 1X day | 4/24/2012 | 1 | Allergies | Massive vomiting. Dizzy and weird heart beat. Was in bed for 10 hours sick. Never again | F | 44 | 1 days | 4/24/2012 | 1 | Runny nose and itching eyes | My normally challenging child -- high energy, silly, rambunctious, etc., began to react with screaming at everything that he didn't like as soon as we started him on it. Yesterday, he absolutely melted down in a grocery store - screaming, growling, kicking, etc. He's never been a model for correct behavior, but he's never been an ANGRY child like this before. He will not be getting another dose. | Zyrtec has provided me with one of the most horrifying, humiliating experiences of my life. I feel horrible that my son had to experience this. I note that there are many people who did not connect their negative behavior with the drug and have suffered years because of it. What a shame. | M | 8 | 14 days 10 mg 1X day | 4/19/2012 | 2 | allergies | headache, short tempered and tired!!! very sleepy after taking zyrtec liquid gel | not a good choice of allergy medication because it makes you very tired. | F | 16 | 2 days 10 mg 1X day | 4/18/2012 | 3 | Skin itching over entire body | Had no obvious side effects except that I have been very anxious, angry, suspicious, and distrustfull of my wife for the past 4 years. She has accused me of not being a "happy" person for the past 6-8 years, Always used to be (or at least I thought) a happy person but was in denial over hte past 4 years thinking it was all her. After reading the posts on this site I realized that it may be the meds. quit them 6 days ago! Itching like crazy but will see what happens. Felt really weird last 2-3 days figure it's withdrawal symptoms | She has accused me of not being a "happy" person for the past 6-8 years, Always used to be (or at least I thought) a happy person but was in denial over hte past 4 years thinking it was all her. Just about ready to get divorced! After reading the posts on this site I realized that it may be the meds. I quit them 6 days ago! Itching like crazy but will see what happens. Felt really weird last 2-3 days figure it's withdrawal symptoms. Need to see my doctor. | M | 58 | 10 years 10 mg 1X day | 4/17/2012 | 3 | Respiratory Allergies | Irritability | I have been taking this drug during allergy season for 2 years now. I took it almost daily from spring through fall last summer, in fact. It was my wife in fact who pointed out that this drug causes irritability. It was so subtle, in fact, that I didn't notice it -- but I was generally not a nice person while I was on this drug, and it took me a long time to figure it out. If I didn't have someone else around to point out the change in my personality, I'll bet I would never even have caught on to it. So, BEWARE of this drug. I was cranky for no reason at all while taking this. Happiness is important to me, so I won't be taking it anymore. This is a drag, because the pill really did help my allergies. Sigh. | M | 40 | 10 MG 1X day | 4/16/2012 | 3 | allergies/follicular eczema/hives. | Had episodes every spring until fall of skin eruptions,intense urticaria,sneezing, nasal congestion.ect...This started out about five years ago and just progressively got worse every year until started to seek actual medical care for condition. Was treated for everything including poison ivy and scabies by primary care for months was on high doses of steroids by mouth and injections,which resulted in high blood pressure,severe weight gain, mood swings, insomnia and the old wonderful pesticide cream for months, that the primary once again insisted that i needed so the rest of my family did not get the scabies.The cream never cleared up anything and my husband whom I slept with every night never had one skin issue.My children who were very young and would occ. sleep with us never had a spot. If you know anything about these pesty critters is, they leave no human unturned, skin is skin and infestation for such a period of time would have infected every family member.After much arguing wi | F | 43 | 14 days 1X day | 4/12/2012 | 1 | allergies | severe stuttering | I am a Speech Pathologist working with young children. I have a student who had sudden onset of severe stuttering. I tried every method of therapy with no real change. I met with parents and they noted that they started Zyrtec around time of stuttering onset. They took him off it and stuttering was GONE, completely GONE. The family did a couple trials and we are all convinced it was the medication. | M | 3 | 6 months 1X day | 4/12/2012 | 2 | Seasonal Allergies | Extreme irritability, mood swings, depression | I began taking Zyrtec once we moved to North Carolina because my allergies were horrible in the Spring. My wife noticed an extreme change in mood and extreme irritability on my part. I noticed that I was more depressed. After her suggestion to quit the Zyrtec, I began feeling more like myself and my mood changed back to normal. I only took this for 2 weeks and could feel the mood shift pretty quickly. If you decide to try this medication, keep track of your feelings and moods! | M | 26 | 2 weeks 10 mg 1X day | 4/11/2012 |
