 1  Seasonal Allegies Almost caused a major accident while driving!!! Difficulty focusing, irritable, lethargic, unable to feel joy in my activities. Very confused and very, very hungry. Watch out. I'm going back to Loratadine (generic Claritin). Works much better esp. in conjuction with a prescription nasal spray. What a yucky day. F 30 1 days

 1  Daughter Eczema & Food Allergies rash all over body, night terrors, relentless whining, hitting, stubborn fits, crying spells over small things, would not play well with others, circle around eyes, fear issues, and became very clingy My daughter has extreme Eczema in the creases of her body (inner elbow, back of knees) which is the worse during the winter months. At first it did a great job of taking her itching away and I was relieved. Her skin went from scabs to normal. Then it came back with a vengeance. I gave her Zyrtec again but, this time it was as if she had become immune. I had to increase the amount given to her to work. She became a totally different little girl. The thing that was most concerning was the night terror which is as is half awake and someone was killing her. Screaming, kicking, crying but not really awake. Then she started hitting her little brother all the time and would not share at all. She use to adore him and pamper him. Instead of making it better she slowly got itchy bumps all over her body. The hard part is watching her itch all over now due the prolonged use of Zyrtec. I am taking her off immediately and looking at diet options instead like Gluten free diets. I am glad t F 3 6 months

 1  Allergies Irrational moods... quick to anger, rage, flat affect, living in a fog, not myself, loss of sex drive, lethargic, sad, weight gain, itchy scalp and face and eyes, general crummy feeling. It never occurred to me that Zyrtec could be a possible reason for these side effects. I literally had to start analyzing everything I was doing or taking to see if I could figure it out. The weight gain and mood and all symptoms coincide with length of time I've been taking it. I take the 24 OTC Zyrtec and try to wait a day between because I'm generally not the person to take any drugs at all... even things like ibuprofen. Birth control pills are the only other thing I take and have been on them for 3 years with no bad sad effects. I really hope that stopping the Zyrtec will make me feel like myself again. F 28 6 weeks

 5  sneezing, wheezing, itchy eyes... I can tell I have been bloated. Increase in appetite. A "little" bit of anxiety. It works so well against allergies. I am happy to put up with these minor side effects for the month of September when my allergies are terrible in Los Angeles. Weeds I guess? It literally knocks these allergies out and that is usually hard fight for me. I have been getting allergy shots (imunotherapy) every week for a year. It cleared all the other allergies throughout the year, but when September rolled around I was still bad. Not as bad as last year. With Zyrtec it was Zero. Nothing else works. F 38 1 months

 1  Hives SEVERE DEPRESSION, severe menstrual problems, anger problems / short fuse, low libido, constant tiredness and feelings of unwellness. DETAILED INFO FOR THOSE WANTING TO QUIT>>>I am absolutely shocked at the state my health was in and the stark contrast to the good health I now have since I stopped taking Zyrtec, particularly my mental health - I just didn't realise how bad it was at the time. I am shocked enough to try and get the word out to warn others who maybe don't realise what taking Zyrtec could be doing to them by writing a detailed description of my experiences (including withdrawal) in a blog: http://zyrtecsideeffects.blogspot.com/ ***NOTE: Please do not mistake the horrific withdrawal symptoms of this drug as being the symptoms that it is 'fixing'. This is a common mistake.*** F 27 18 months

 1  allergies complete fog and depression. i have been diagnosed as bi-polar but am not currently medicated for it. i am fine (not manic or depressive) if i keep my system clean. (meaning without drugs or alcohol of any kind). i started taking zyrtec two weeks ago and have non-stop crying fits, lethargy, thoughts of suicide and deep depression. i tried not taking it for a few days and realized my head was clear, (my sinuses weren't) and my mood was back to normal. i could function again and the crying stopped. I don't think it effects everyone this way. But I think if you have some sort of chemical imbalance to begin with, it sets off the depression. I would NOT recommend this medicine. F 27 14 days

 1  allergies excessive irritability, loss of concentration, zombie-like state, general stupid feeling, poor memory function, general foggy daze, excessive unrestful sleep - in other words why bother logging 8-9 hours when you wake up and feel like you need to go back to bed. take this and you will feel like a P.O.S all day. Get used to the affects of this drug and become a P.O.S. This drug hammpers quality daily life. I was more alert smoking bongs all day when i was in college. This drug is bad! Look for alternatives. Something is wrong with this medicine! Everyone I have spoken to agrees or has similar stories. Everyone's comments on this web site are right on with respects to symptoms. The ones who do not have side affects may not realize they are having problems depending on their occupation, daily activities, etc. comments for healthy Zyrtec users: Children generally do not complain about things and dont know what is or should be or feel right. The same is true of individuals who do not know what feeling good or healthy is. M 39 24 days

 1  Seasonal allergies DEPRESSION, sleepy I've been trying to figure out what the heck was wrong with me. I was a very down to earth happy go lucky person until I started taking Zyrtec a week or so ago. I didn't know what was wrong. Thanks to all of you for actually taking the time to post. I won't take it anymore. F 44 10 days

 3  Itching and allergies This medication worked at first however, after about a year I started to notice itchy red bumps on my skin, severe eczema which spread all over my body, mood swings, anger issues for no reason at all, mussels hurt, sore stomach, very sore breasts, hair loss and no sex drive at all. I also noticed that when you try to get off the drug you can experience up’s and downs with depression and feeling useless at times and yes intense itching that only Excedrin and benadryl helped! I have taken this off and on over a three year period. I would not take this drug unless nothing else works for you and even then I would take it only as needed and not everyday. F 46 3 years

 2  Year Round Allergies I take zyrtec at night before going to bed. I find that I have problems waking up in the morning. It's as if I am in a drugged stupor. I had been taking allegra-d but was told that I needed to switch up my allergy medicine so that my system did not get used to the medicine. I have been on allergy medicines since I was 20.

 1  Allergies. Zyrtec suggested by doc Gained 6 pounds in 1 week despite also being on antibiotics that caused stomach issues. Have been off the antibiotics for almost a week and still haven't lost the 6 pounds. No doubt that the Zyrtec caused this. Very blurry vision in the evenings (about 8-10 hours after taking it). Spacey feeling all the time. Face looks sunburned, but that may be from the antibiotics. Helps for a few hours, but no where near the 24 hours that it is supposed to. I realize it's effectiveness is essentially a bellcurve with it peaking a few hours after taking it and slowly wearing off. But, if I take it in the morning, by 2pm, it's worn off. If I take it at lunch, it gets me to about 7pm. So, only works for about 8 hours for me. It's either breathe during the day or breathe at night. Allegra and Claritin do nothing for me, either. Was hoping this would work, but so far, it hasn't. I gained weight on Allegra, too. Quit taking it and the weight came off. But, now that fall has arrived, I've got to start back on something else.

 1  seasonal allergies Anxiety and panic attacks, unusual tiredness, irritability worked well for the allergies but not worth the side effects. I thought I was losing it. There was no reason for me to be axious yet I could not control the overwhelming panic I felt. Zyrtec was the only new drug I had taken, the symtoms stopped when I stopped taking it. F 43 15 days

 4  allergies NONE My son has been taking zyrtec for about 3 years and has had NO side effects. He is a great student with no behavioral issues. We even get comments from people in public about how well mannered he is. It is actually the only medicine that keeps his itchy eyes and nose in check. We've also added an over the counter allergy eye drop by Similisan. We notice a big differnce within 2 days if he has not taken his pill. Thank God for Zyrtec. M 7 3 years

 1  seasonal allergies My 9 year old son started zyrtec on a daily basis at the end of August to help with seasonal allergies that trigger his asthma. He started becoming extremely emotional both at home and at school. Knowing that normally he would never cry at school if he could help it I started questioning the Zyrtec. I decided to take him off for a week and see where we were at and immediately saw improvement at home. Then I was called into the classroom by his teacher because she wanted to tell me what a huge change she saw at school overnight! She explained that she was very worried about my son's transition into 4th grade but now she is confident he is doing fine! She claims he is like a whole different kid in the classroom than what she has been witnessing the 3 weeks prior since the start of school. I would decribe his side effects as fatigue, lack of concentration, weepy, depressed. If your child is suffering from anxiety, depression and being very emotional take them off Zyrtec! Huge improvement over night! M 9 1 months
