| 1 | Allergies | Heart palpitations, extreme anxiety, depression to the point I would burst into tears at random times. | The active ingredient in this drug is cetirizine hydrochloride, and quite frankly it should be banned. I'm a confident social person and I took this drug for a month. During that month I felt like my heart rate was over 100 most of the time. I was depressed and had severe debilitating anxiety. I simply could not function and most mornings couldn't physically leave the house to go to work. When I was at work I would go into the toilet cubicle and be unable to walk out of there. It was frightening being like that. I would cry for no reason despite not being a crier. Normal situations were starting to cause extreme anxiety to the point where I would just want to shut myself away from the world all the time. It took WEEKS for me to get back to normal after taking it, so don't be alarmed if you're not back to your old self in just a few days. This drug gave me the worst month of my life. Please don't take it, especially if you are in any way an anxious person to start with. This drug completely changes your personality while you're on it and makes day to day life very difficult to cope with. It really should be banned. | M | 32 | 1 months 10mg | 9/9/2015 | 1 | for hives | Nausea and dizzy I cant go outside I fant every time I try..can eat cant sleep my nerves system cant stop shaking headache eyes blurry light headed cheats pain shortness of breath vomiting passing out fever and chills | We need to do something about this!! | M | 28 | 1 days 1 pill | 9/3/2015 | 1 | Seasonal allergies | I could not believe when I found this site and read all of the comments. I've been experiencing all of the same symptoms but never contributed them to taking Zyrtec. I've gained a lot of weight, I'm always bloated and gassy, lethargic, depressed and moody. I haven't felt myself in quite some time. | A side note to this for all of the women out there, is that a lot of these symptoms are similar to those of Ovarian Cancer. My mom was recently diagnosed and had many of the symptoms we've experienced taking Zyrtec. So if you are able, please get that checked. It's called the "silent cancer" because it's symptoms are easily dismissed! | F | 38 | 9 months | 9/1/2015 | 4 | Seasonal Hay Fever | Dry nose, nasal crusting, blood in nose, mild drowsiness | This stuff works well on hay fever, maybe a little too well because I can only take half a pill and I'll be good for about 3 days. It does make me a little bit drowsy so I take it at night, sometimes I wake up and feel fine, other times I've felt a bit foggy but it wears off. It also dries up my nose because it's strong, I get a lot of crusting and blood due to the dryness. However these side effects are tolerable and better than having bad hay fever. | M | 27 | 3 months 2X W | 8/28/2015 | 1 | Seasonal allergies | Daily drowsiness, severe funk, increased appetite. | I was so relieved when I came across this site! Just spent an entire weekend in a horrible funk!!!! It's Monday and I couldn't even work from home. It's like my brain was sleeping. I gave up and slept for 2 hours after a full 8 hours of sleep the night before. I am normally a high energy person so I thought I was losing my mind until I realized the only change is I started Zyrtec last week and was told by the pharmacist for best results take it daily. He said for best results take it everyday whether you're experiencing symptoms or not. When I woke up I decided to Google Zyrtec side effects and it wasn't until I found these consumer comments that I know to quit taking Zyrtec!!!!! | F | 45 | 7 days 10 mg 1X day | 8/24/2015 | 1 | Year round indoor outdoor allergies | Irritability, severe depression, lethargy. | On this for probably 15 years after trying so many others that either didn't do the job of muting the allergies or their side effects were completely unbearable from the start. While Zyrtec works for the most part, I did notice that my body wasn't responding to the anti allergy effect as well- still suffered on this. Went off a few weeks ago because the depression is changing who I am - and I feel like I actually went ON an antidepressant, it's that much of a difference being OFF this drug. Into week 2 1/2 or 3 without: hands are swelling, hot and itching like crazy- feet to a lesser degree. Been reading that this is common withdrawal. We take these pills for years like its nothing but the withdrawal is evidence that we've become dependent on it. | F | 40 | 10 years | 8/15/2015 | 1 | Seasonal allergies | My son was experiencing seasonal allergies and rashes due to moving into a rental that previously had cats and dogs. After many sleepless nights of scratching himself to the point of bleeding, I took him to an allergist who recommended 5 mg of Zyrtec each day. I had him taking 1/2 of the dissolvable tablets with no noticeable side effects. A few days ago I switched to the liquid and he's been an emotional wreck. He's unable to cope with any changes or upsets. He has thrown several tantrums that last for an hour or mor, and he also started waking up in the middle of the night screaming from nightmares. My husband suggested it may be the Zyrtec and low and behold, I find this thread. I will never use Zyrtec or any other allergy medication after reading the experiences on this site. Thank you for all of your helpful stories. | M | 3.5 | 1 months 5mg | 7/29/2015 | 3 | hayfever symptoms | Itchy toes, others I'm not sure about. It also isn't absolutely successful in stopping hayfever symptoms, mine were only reduced. | I've taken a generic version of Zyrtec for about 3-4 years, often missing doses and only taking pills when I felt symptoms coming on, so I can't be certain of the links between it and my experiences. I also take it far more regularly in winter than in summer. I found many negative reviews about Zyrtec a couple of days ago, and many side effects described were eerily similar to what I've experienced these past couple of years. Bad temper, mood swings, depression, insomnia and sleeping too much were things I noticed in the colder seasons, which I used to always pin on just being a teenager/the weather etc. It's currently winter where I am, and to test my theory, I stopped taking Zyrtec yesterday. Today, I feel different, anxious, I woke up much earlier this morning than usual, and I think I have itchy hives on my toes, which I used to always take Zyrtec for after noticing it. I'll update this review later on. | F | 17 | 3 years 10mg 1X day | 7/16/2015 | 3 | Allergies | Drowsiness. | Could not stay awake with this medication. Would sleep for 10-12 hours and still feel tired after getting out of bed. I even tried splitting the pill to make 5 mg dose, but still felt very drowsy. This medication works, but the side effect is just a shame. | F | 26 | 2 days 10 mg 1X day | 7/13/2015 | 2 | Moodiness not sleeping well my friend asked about what allergy medication she was taking and now I think I have found the reason for her outburst. I am still going to have her see a therapist just in case it is so something else. I think the medicine has a lot to do with her outburst though and her lack of sleep | F | 11 | 1 years 30mg | 7/3/2015 | 1 | Seasonal allergies and dog allergy | WEIGHT GAIN!!!! | While this worked great for my allergies I have gained 20 pounds with refular daily use for the lasr year. Stopped taking it and am already shedding pounds after 1 week | F | 50 | 1 days 10 | 6/22/2015 | 3 | Allergies to several things | My daughter has statted Zyrtec for her allergies and she has always been our quiet and calm child. I have noticed though since she's been on it she has gotten worse with her attitude. She will scream at us, screams the hole time she is in time out, and will smack her sister for nothing. She just told me today she gets this feeling in her that makes her mad and want to hit people,scream,& throw things. This is not our little girl at all. I seriously think it is the Zyrtec because she was never like this until she was put on it. School she is stil quiet and shy but I am afraid she is going to start acting out and I do not want that for my child. I will be calling the allergy doc for sure after all these comments. | F | 6 | 1 days 8ml | 6/19/2015 | 1 | Allergies, dust mold mites dander | Zyrtec did not produce drowsiness for me. Also was ineffective at controlling symptoms of pollen, dust, mold or dander allergy. | ineffective | F | 6 months 10 1X day | 6/16/2015 | 2 | runny nose and cough | Made me so drowsy that it felt as if I was under anesthesia or about to pass out. During the day on the weekend, I would fall asleep and have bad dreams. Am so tired and dizzy during the day that I can't get anything done. Also caused painful headaches, agitation, irritability, and low mood. It is labeled as non-drowsy but it must cross the blood brain barrier because of the drowsiness and mood changes it caused. | F | 37 | 2 weeks 5 1X day | 6/15/2015 | 1 | Seasonal allergies | My son took this for four days and instantly started having trouble sleeping ( started sleep walking, opening doors) he even said he hated his life and got aggregated while trying to get him back to bed .... This drug should not be used as a OTC!!!!! | M | 9 | 4 days 10MG | 6/5/2015 | 3 | seasonal allergies | Extremely dry skin all over especially on face ..flaky eyebrows and dry Cracks around my eyes and mouth....even dry.using vasceline on my face. Severe rash and itching on hands and wrists. My skin and body dry everywhere. | F | 56 | 4 months 10mg | 6/4/2015 | 1 | Allergies | SEVERE ankle and leg swelling - EXTREMELY painful. Was cranky and could not sleep very well. I do believe that I may also have RA, so this could be a factor. Stopped taking medicine on Saturday, and as of Thursday, most of the swelling is gone. What an AWFUL experience this was until I figured out what was causing it. | F | 45 | 45 days 10 mg 1X day | 5/28/2015 | 1 | allergies | horrible anxiety and irritability | I have worked in the mental health field for 23 years and now understand what my clients experience. Took a zyrtec and it sent me into a 48 hour funk that scared my wife and my kids. Thank god it was a long weekend or I would have had to call in sick on Monday. I thank my training and experience for totally not freaking out. I knew something was very wrong and that I needed to be alone so I would not act out against the people I love. Horrible drug that could lead to some very bad actions by the people who take it. Would much rather have allergies. | M | 46 | 1 days 1X day | 5/26/2015 | 1 | Seasonal Allergies | Nausea, joint paint (especially hips and shoulders), extreme irritability, crippling fatigue, cannot concentrate, terrible ADD symptoms, brain fog, cannot get out of bed, anger/rage, deep depression, heart palpitations, horrendous weight gain, soul-less feeling, zero interest in life. | I began taking Zyrtec in March to battle seasonal allergies and did not realize until today all the horrible side effects I have been experiencing are from this pill! I take 1 Zyrtec at night, right before bed due to the extreme drowsiness it causes if I take it during the day. I am a certified nutritionist and adhere to an extremely regimented diet and exercise plan. I have a ton of self control when it comes to diet and exercise and typically maintain a weight of 115 lbs. Over the last 2 months I have gained 10+lbs without a single change to my routine. Over the last 2 months my weight has been slowly creeping up. So I have increased my cardio and reduced my calories even farther and my weight will not budge! I cannot even fit into my pants anymore! I was so desperate for answers that I thought I may have a thyroid disorder. Over the last week I have been racking my brain trying to figure out what is wrong, but now it all makes sense. Zyrtec really helped my allergy symptoms however it will ruin your life! Update: Stopped taking Zyrtec cold turkey. Day 1: terrible splitting headache and nausea with frequent urination. Day 2: Very bad nausea and vomiting, stomach upset, blurred vision, spacey feeling, itching. Feels as if you are coming off some crazy narcotic!!! This stuff should be taken off the market. | F | 32 | 2.5 months 10mg 1X day | 5/23/2015 Patient History | 1 | Seasonal allergies | My 10 year old son. Has been having uncontrollable anger outburst. Also crying easily. I have been doing research to find a cause and help for my son. After reading this I am stopping Zyrtec TODAY notifying his MD. By the other post it seems zyrtec could very possibly be the cause. | M | 10 | 5 years 10 mg | 5/14/2015 |
