 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

 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

 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.

 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

 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

 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

 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

 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

 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

 3  Allergies/Asthma Moderate Depression and Mood Swings, Tinnitus, Decreased Libido Been off it for 2 days, and my mood and sex drive back to normal... It did help the allergy symptoms, though. Given that it helped me breathe, I guess it was worth it. Now that the mold we had in the house is gone and dissipating, I'll be saying goodbye to this drug for the foreseeable future. M 30 14 days

 1  lung congestion with cold Breakthrough menstrual bleeding, after three years in menopause, extreme dry cracked lips and skin Worked well for drying up the congestion, however the side effects were horrible. My lips dried up and chapped and cracked to bleeding beyond recognition and 8 days later I'm still slathering them with lotions and vaseline to help heal. Skin itching and irritation and worse yet....I began to menstruate, although I went into menopause three years ago! All this even though I was drinking tons of water-- a big glass every hour while taking it because I knew of its dehydrating side effects. I did find a site that mentions break-through menstrual bleeding as one of its side effects. 8 days later, I'm still experiencing it, had no issues with this for years until the day after the first zyrtec!!

 1  Severe Allergies and asthma Anxiety, loss of concentration, depression, and major withdrawal symptoms if I miss a dose (I forgot to take it last night and have just used a box of Kleenex in sneezing repeatedly for 2 hours, with a major headache, and swollen sinuses.) After several years of exemplary performance in my job I've just received a second warning in 6 months regarding errors in my production, and unkind and even aggressive inter office communications. Since I know that this is not my MO, I've tried to assess what was different about my habits- medications that may have contributed to this -Zyrtec is the only medication that has been a consistent factor during this period of time. I've taken this drug religiously for 4 years - it has helped control the histamine production and subsequently helped to keep my asthma in check. But now I have to reconsider my options; if this causes me to lose my job I will find an attorney to help me sue the manufacturer. F 57 4 years

 1  Seasonal allergies Depression, anxiety I've been taking Zyrtec from the age of 6 when it was a prescription and have taken it for about 7 years. When I was young, the medicine worked well and I could notice a difference when I stopped taking it but as I got earlier my body may have gotten used to taking it everyday because then it stopped working. Last year I started taking Allegra D, and that worked fantastically so this year I thought I might start Zyrtec again because it's cheaper for the most part and easier to swallow without water (when i forget and have to stuff one in my pocket to take on the go). I bought Zyrtec about a month and a half ago since the weather warmed up realllyyyyyy early this year and started taking it. Ever since then I experienced mass amounts of depression. not sure if this is soley related to Zyrtec but I did relapse into a cutting habit I gave up 2 winters ago so I figured it was because something triggered my depression again.
