| RATING | REASON | SIDE EFFECTS FOR ZYRTEC | COMMENTS | SEX | AGE | DURATION/ DOSAGE | DATE ADDED |
| 1 | allergies | All drugs are poisoness eventually; but most things can be cured with vitamins | No problem with vitamin C crystals, can even cure mono (e.g. a teaspoon every few hours until gone); see doctoryourself.com. | M | 56 | 1X day | 3/17/2012 | 1 | allergy sinus pressure and pain | stomach pain, nausea, diarrhea, fatigue. 12 hours after taking the medicine I feel horrible and lethargic. Parts of my body have a strange, tingling feeling. I feel like I'm someone else. Strange. | I would never,ever take this medication again, even though it stopped my sinus pressure and pain. | F | 56 | 1 days 10 mg 1X day | 4/9/2012 | 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!! | F | 56 | 2 days 30 1X day | 4/10/2012 | 1 | Hives (urticaria) | Dizziness, full feeling in head, feeling of muzziness and dislocation | No effect whatsoever in reducing the incidence or severity of hives | M | 56 | 2 months | 9/26/2005 | 1 | seasonal allergies and rash | irregular/racing heart beat, dizziness, headache, joint pain, depression, vivid often bad dreams | I wish I would have realized that Zyrtec was causing these side effects sooner. | F | 56 | 3 months 10 1X day | 3/9/2015 | 1 | For allergies | This seemed to work fine but I always had a running nose. I decided to stop taking Zyrtec and the side effects were horrible. I was getting heart palpitations, depression and a feeling like I was going to die. I felt anxious and very tired. I had to go back taking it again. A week ago, I started taking 1/2 a pill everyday and only had slight side effects. Slight heart palputations and no feeling of depression. In a few days I am going to skip a day until I no longer have this poison in my system. | Don't ever start taking this medication. It messes you up and it takes away a part of you life. I rather suffer with allergies than to go through these symptoms again. | F | 56 | 5 months | 8/16/2009 | 1 | Seasonal allergys | Irregular heart beat. Either PAC's or PVC's. Terrible shaking. Vision problems. I quit taking it and the shakes and irregular heart problems went way. My vision has not returned to normal and it's been a few months | Are there any class action suits againt the makers of this terrible drug. I'm an RN and I can't believe Zyrtec is allowed to stay on the market | M | 56 | 10 days 1X day | 5/21/2014 | 1 | allergy symptoms | Extreme drowsiness, irritability. | I took this because it's advertised as non-drowsy. Not. I can't even function when I take it and it lasts all day. Not until I looked at this site did I attribute my irritability to the drug. But now I realize my edginess and anger coincides with the taking of this medication. | F | 56 | 3 days | 6/5/2008 | 1 | Spring allergies | Mood and personality changes | My husband, a normally gentle soul, became depressed, angry, irritable, and short-tempered within a week or two of taking a generic brand of Zyrtec. This medication had been recommended by a co-worker who also runs an allergy office. My husband stopped taking the medication. In speaking with another co-worker whose child was taking Zyrtec, she said her daughter was experiencing the same symptoms. | F | 56 | 2 weeks | 5/27/2008 | 1 | seasonal allergies | Lethargy, sleeplessness, high blood pressure, irregular heart beat. | I started taking this drug because I was out of my normal presecription (Allegra) and I was travelling out of town. The result was a difficult few days as I tried to stay focused during meetings with little sleep the night before. The headaches and flushed feeling were constant. Upon returning home I took my blood pressure and it was through the roof. I would look carefully at your condition before considering taking this drug. | M | 56 | 4 days | 6/28/2008 | 3 | Sinus and congestion | Major side effects. I was not able to function due to feeling spacey, light headed and just plain out of it. Could not sleep and would go in between of relaxation and then aggegtiom. With that being said it did clear out my sinuses. | Medication works but due to side effects I would not take it again. Be cautious and don’t plan to leave the house | F | 57 | 1 days 1X day | 3/26/2018 | 2 | year round allergies | Usually would sleep a max of 6 hours. Started sleeping 10. No problem with falling asleep at night. Usually bounce out of bed ready to go in morning but not after taking this drug. Allergist insisted I take it at night and I see why. Also take Singulair. Don't like the fuzzy feeling and lack of focus with inability to start any projects. Just feel lost. | Stopped taking this two days ago. Shaky and weird feeling yesterday, and noticed hunger pangs which I haven't had for awhile and have been forcing myself to eat. Was never hungry. Great diet drug? I got two hours sleep last night. Could not fall asleep! 4:30 a.m. and woke up at 6:30. I had taken Allegra last night per my Dr and realized it's a drug I have to take in the morning. Clarinex is what we try next if Allegra doesn't work. Zyrtec had my nose running and drainage in back of throat so was it working on allergies or not?? My husband took Zyrtec and could not function, and my step-daughter tried it and can't function either. I have a two yr old granddtr on it and printed out these comments of parents who used it for children. Hope she quits giving it to her! | F | 57 | 7 months | 5/21/2008 | 2 | allergies | Extremly sleepy, couldn't function. I felt confused and irritable after just one dose. Kept yelling at the dog. After one dose, I discontinued its use and called my doctor to ask for a different Rx. Now, just one night later, I'm still awake at 4:00AM because I've been itching. I didn't connect the itching to the Zyrtec until I crawled out of bed and read all the comments about itching and hives. Also I developed a bad cough that doesn't seem to have any cause. I didn't see that effect on anyone else's comments. | After just one day on this medication I can't even say that it helped my symptoms all that much. Maybe it takes more time to kick in. | F | 57 | 1 days | 4/22/2005 | 1 | hives, itching | Severe heart palpitations | I have been taking zyrtec for one year; also have been suffering heart palpitations and blaming other meds. After researching zyrtec I realize that's likely what it is and have stopped - just 2 days ago. I don't yet know what other symptoms I'm experiencing (anxiety, muscle twitching) have been related to zyrtec, but look forward to findout out when this drug is out of my system. | F | 57 | 1 years | 5/17/2007 | 1 | severe allergies and sinusitis | Severe edema, elevated eye pressure, hives and itching upon trying to stop zyrtec. Anxious to see how long after stopping the zyrtec edema and eye pressure are affected. | Though zyrtec worked to control my allergies, the addictive nature of the drug scared me. I have tried numerous times to get off it and the terrible itching and near panic attacks drove me crazy. I have now been off it for a week and am trying to put up with the itching with OTC Claritin. I have found that ice helps calm the nerve endings. NO DRUG IS WORTH THIS KIND OF WITHDRAWAL! How long before it's completely out of one's system? | F | 57 | 8 years | 5/22/2006 | 1 | Allergies | Swelling of eyes and face. Itchy eyes and face. Depression, bad dreams, tiredness | I could not understand why I was not getting better. I would get so bad I could not go out in public sometimes not being able to open my eyes. I would go to the doctor and he would tell me to keep taking this pill. Now I realize all along it was the zyrtec causing these reactions. Within 4 days of stopping the pill my face is back to normal, the red scally patches are gone and I have more energy. | 57 | 3 months 1X day | 1/24/2013 | 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 10mg 1X day | 4/9/2012 | 1 | allergies | itching all over my body, developed vaginitis | F | 57 | 3 weeks 30mg 1X day | 4/14/2010 | 1 | Seasonal allergies | Depression, moody, extreme anger over small problems, feeling of being overwhelmed and out-of-control | Took this for three days - noticed the extreme anger and depression on day two - I'll go back to Claritin | F | 57 | 3 days | 12/11/2008 | 1 | Allergies (?) Indoor & Outdoor | Irritability, increased appetite/weight gain, lethargy, increased sleep, flat effect, brain fog, unexplained rashes, vision issues.....still figuring this out.... | This drug should be only used in emergency & real allergy testing done immediately to rule out causes and focus on the real allergy, dairy, gluten or fake additives in our food, made worse by environmental triggers (aka indoor & outdoor allergies). Experienced extreme withdrawal symptoms while going off for 5-7 days to get allergy tested. Will never take again, was diagnosed with food allergies, so no need. Researched other alternatives if seasonal or indoor & outdoor allergies become bothersome. | F | 57 | 9 years 10 mg | 10/8/2015 |
