| 4 | Allergies, nose congestion | Dry mouth, sleepiness | Constant desire to masturbate while watching golf on television. | M | 50 | 6 days | 6/7/2008 | 3 | allergies | Switched because OTC Claritan was ineffective at the suggested dosage. Zyrtec seemed effective, but I notice extremely dry mouth--right around the inner area of my lips and a salty taste on and around my lips. | M | 50 | 60 days | 7/3/2008 | 3 | allergies | lethargic | F | 50 | 1 months | 2/20/2009 | 3 | HIVES | WEIGHT GAIN (7) LBS DIZZY HEADACHES IN A FOG BODY TIRED | F | 50 | 28 days 10MG | 1/24/2022 | 3 | Allergies | I have taken Zyrtec probably since about 1996. I noticed whenever I tried to stop taking it I would get itchy. If I take it then it stops. I always thought that was why I was taking it to stop the itching. Now after reading other people's ratings, I am finding out that trying to stop it is what is causing the itching. I always take it at night, because at first it did make my sleepy. If I don't take one at night by morning I am starting to itch, palms of hands and feet, head, arms. I am going to see if I can get off of it and the itching goes away. Claritin just doesn't stop the itching. | I am shocked that what I might actually be experiencing is withdrawal from this medicine. Another way the pharmaceuticals get you hooked. I didn't notice a weight gain that I would blame on that, but maybe if I start losing then I'll know. | F | 50 | 12 years | 3/31/2008 | 3 | itchy rash | The Zyrtec combined with a topical cream helped but I became agitated and irritable. I had trouble concentrating and had wierd dreams. I am taking 10mg tabs but will try 5mg then quit if I feel this way- it isn't helping THAT much. | Thanks for this site...I was wondering if anyone else felt this way. | F | 50 | 5 days | 8/30/2007 | 3 | seasonal allergies | Irregular heartbeat | I hate that this med causes this problem for me, because it worked fabulous on my post nasal issues. I just can't handle the skipping heartbeats. | F | 50 | 40 days 5 mg 1X day | 4/1/2010 | 2 | hives | I felt so drugged i could not even function. Still feeling the effects 24hrs. later. | Did take care of hives | F | 50 | 1 days | 5/10/2006 | 1 | Allergis | HORRIBLE attitude, tired, drowsey, ancious, weight gain, snappy, rude, stuffed up nose, dry nose, headache. | M | 50 | 14 days 10 1X day | 10/25/2011 | 1 | Allergies | While it controls my itchy throat and eyes; I am completely exhausted and suffering from weight gain and very achy joints, especially knee and wrist. | F | 50 | 60 days 10 MG 1X day | 3/30/2013 | 1 | Allergies | Sleepiness, being in a dream like state, memory lapses | I took one table for severe seasonal allergies and Zyrtec did relieve my congestion however the following morning I overslept, and awoke feeling like I was in a dream. The entire day was a blur and when I came home I was so exhausted I took a nap. This may work for some people but I won't be taking it again. Ever. | M | 50 | 1 days 1 tablet 1X day | 4/15/2010 | 1 | Year round allergies | Drowsiness, headaches, nosebleeds, weight gain, diarrhea, constipation, cramps, flu like symptoms, blurred vision, upset stomach, numbness, shakiness, hair loss | I did not connect all of the side effects until I found this web site today. I even talked to my pharmacist two days ago. She said it was no side effect from the medications I use and the nosebleeds, headache, etc. may be due to a sinus infection. What a pant load! After reading the feedback here, I will not take Zyrtec any longer. I will immediately begin with my old standbys, i.e. Claritan or Dexchlor. I had used Zyrtec before (about 3 years ago for 1 year) and never connected the dots. I will definitely ask my doctor to add this as do not use to my medical record. I watch my diet, drink about 80 oz. of water per day, etc. Go figure? | M | 50 | 8 months | 8/3/2007 | 1 | To control allergies | Terrible! First day got sleepy and lethargic , second day face flushing, sweating, headache and nosebleed . This is it for me, I can't not imagine what other side effects I will get if I continue with this medication so I stop here at day 2. | F | 50 | 2 days 10 mg 1X day | 8/16/2021 | 1 | hayfever | extreme anxiety, dread of the future, depression, irritability, unable to emotionally connect with family, brain fog, unable to focus, terrible short term memory, could not focus on others talking | I was taking 5mgs 3 or 4 days per week as needed. I did wake up depressed some days but never made the connection to taking zyrtec the night before. I increased to 10mgs per day, every day for the last 40 days ( too lazy to cut the tablet in half). Then came the hopelessness, anxiety like I haven't had in decades, extreme irritability, panic attacks and obsessive thoughts, dread of the future. I have lost 4kgs (53kgs to 49kgs) in the last 3 weeks from the anxiety and being unable to eat. I was also bored with TV, books etc. Zero motivation. I am glad I increased the dose to 10mgs and felt the full effects of the dose, or I may have attributed my irregular episodes of depression to something else. Stay away from this drug! I am tapering off of it now and am now at 3mgs, and the withdrawal effects (histamine rebound) have been headaches, diarrhoea, anxiety, depression and insomnia. I will never take this drug again, and neither will my children. The mental health effects have been like nothing I have experienced before. | F | 50 | 40 days 10mgs 1X day | 3/29/2024 | 1 | for pollen allergy | depression, lethargy, crying, sleepiness during the day, insomnia at night, dullness, nervousness | it helps for allergy but it has horrible psychological side effects... avoid this medicine | F | 50 | 2 months 5 mg 1X day | 9/15/2022 | 1 | Allergies | Laundry list of side effects! Fatigue, Massive brain fog, depression, Tremor, inflammation, stinging burning pain all over, Dry eyes, eye swelling, 20 pound weight gain, Etc. This medication has turned me into a bed ridden zombie. I am going to wean off and then throw all my bottles out. I’ll stick to Claritin in an emergency. | F | 50 | 3 years 5 ml 1X day | 10/28/2020 | 1 | Body Rash | Severe fatigue, ill feeling, headaches, tightness in forehead | Took increasingly high doses to keep red spot body rash at bay. It did that very well. However, side effects are debilitating. Didn't realize the drug was causing all of this until weaning off and seeing side effects start to disappear. Fatigue started to disappear within 24 hours of stopping. Ill feeling started to fade as well. Headache has been a bit slower to fade, but after 3-4 days is almost gone with only minor tightness in scalp remaining. GP said that Zyrtec wouldn't be the cause of this.....oh well. | M | 50 | 45 days 20mg 2X day | 11/8/2018 | 1 | allergies | irritability, anger, sadness, insomnia | I took Zyrtec daily for 3 years and noticed no side effects. It worked great for relieving allergy symptoms. Then suddenly, about 6 months ago I began feeling over angry concerning the smallest things... I pulled my wife's hair for running out of jelly and stomped to my bedroom and locked my self in my room. It took me about 3 months to figure out my daily rage was caused by the zyrtec. As soon as I was off the medicine, my rage feeling left me, but the withdrawal symptoms were bad. I still have stomach aches, get angry easily and feel sad for no reason at all. I hope this is not permanantly in my system. | M | 50 | 3 years | 9/12/2008 | 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 | 1 | Demographism, Hives and Allergies | Everything everyone else said is absolutely true. This drug may help with the severe itchiness and hot feeling underneath the skin and hives but the side effects are truly unbearable! - It shuts me down for at least two or three days! I truly cannot function while on this drug. I experience extreme fatigue and it is impossible to function. It is a terrible state of mind to be in because you need to live your life and do things. With this drug, your emotions are all over the place because you wonder to yourself, what is wrong with me? You cry, you feel as though you're going crazy and you can't function and you have things to do. It totally shuts down your life. It's like a mind control type of thing. All you can really do, is sit there and feel totally, totally out of it and feel down, super, duper groggy and depressed and hopeless. - I feel this way whether I bite a piece off of a pill on take the whole thing. This pill totally controls your life. - - All of this, just to try to g | It's a shame that a drug whose milligrams are so small, could cause such a huge effects of tons of people and the manufacturers and Food and Drug Administration would not do anything to make them edit the drug to prevent these horrible, horrible mind and body controlling effects. All of this simply to prevent itching. - What a shame! - What's even more, is that right now, I have no choice but to take it . . . because I suffer so badly with the demographism and hives. | F | 50 | 10mg 3X W | 8/12/2017 |
