 5  sinus and skin allergies I suffered for years with allergies, until about 12 years ago when my (female) dr. finally listened to me and did allergy testing. I reacted to everything. I took Claritin for a long time, which changed my life. After awhile it stopped working as well, and I've taken Allegra and then Zyrtec. Zyrtec works better than anything I've tried and I don't notice any side effects. However, recently two doctors have told me I have to get off of Zyrtec and I'm wondering why. Maybe it's because the HMO doesn't like to pay for it. F 44 1 days

 1  Sudden Onset Of Hayfever No waiting to find out. Had a similar experience of loss of creativity and motivation when taking VIOX and found out 3 month's later that it was BAD! I will try to minimise exposure to pollen instead. heavily advertised on Australian TV. First thing recommended by pharmacist when I went for help as the runny nose just wouldn't stop. Never had hayfever before. Suspect the cause in in processed food!! M 47 1 days

 3  allergens, in and out drowsiness; out of it feeling update:after being off zyrtec for 2 mos., decided to try zyr again (take it at night), felt drowsy, out of it, and also irritable with no energy. i'm sticking with Allegra where I feel like a human being. also, all of sudden i was able to lose weight in the last 2 mos. -- reading other posts, wonder if the zyrtec was the reason i kept gaining not losing?

 1  allergies Irritable, sadness, poor impulse control, crying spells, insatiable appetite. My son is 5 and began taking Zyrtec 2 weeks ago for allergies. The first two days I was giddy with happiness because my sneezy, itchy snotty, miserable son had started waking up bright eyed and bushy-tailed. Then I realized how much his behavior was changing. His teacher started saying that he couldn't seem to control himself in class. Couldn't make a decision during choice time...on and on. She said it "wasn't like him" and wanted to know what was going on different. He also started crying more often for no reason and having strange dreams. And last, but not least, he started chasing and scaring our cat who he used to be so gentle and kind with. When I asked the doctor about the side effects, she was very blasse' about it. After reading the other comments about Zyrtec and kids on this site...I will never give it to him again. DO NOT GIVE YOUR CHILDREN ZYRTEC. IT IS NOT WORTH IT!!!! M 5 2 weeks

 5  Lots & lots of allergies Dry mouth, dry sinuses, mild dizziness I'm allergic to just about everything in NC (where I live) and Zyrtec, along with allergy shots, helps me feel almost normal! After 4 years, however, it is losing potency and I'm going to have to switch to something else, but it really has helped me a great deal, with mild side effects. F 34 4 years

 1  allergies to pets tired, disassociated, depressed, sad, insomnia At first I was tired all the time. I took it at night and then drank strong coffee each morning. I seemed to be functioning well enough. Then I started getting more and more "spacey" during the day, and more tired. Then I would be so exhausted all day but not be able to sleep at night. I thought it was the coffee. Then I started getting very 'sad'. I just cried all the time until one day I had a total emotional breakdown and couldn't even go into the gorcery store because I couldn't stop crying. It dawned on me that I needed to research Zyrtec and I found this site. I think it quite literally may have saved my life. I haven't been taking it for several days now and feel better every day although I am itching everywhere. Of course my allergies are killing me! My 10 yr old had been on it but got very "crabby" so I took her off of it. A friend told me that her child hadn't handled it well, but that she loved it, so I thought it just wasn't good for children F 45 7 months

 1  Seasonal allergies--ragweed Very sleepy, not feeling like myself, feeling depressed and out of it. I was told to take zyrtec non-stop until the stuff builds up inside my body and protects me from the allergens. Well, I feel pretty dang bad..depressed, sleepy and hopeless. This is not worth it. :( F 52 4 days

 4  rhinitis and other allergy symptoms We are curious if this has affected his growth. He was 85% (height/weight) at birth and is now 25% (height/weight). My wife and I are both quite tall. She is 5'9" and I am 6'3". Just thought I would post this in case someone else sees the same thing. Symptoms have subsided fairly well. Without this our son required using the nasal tool 2-4 times per night. Now, more than half the time we don't even use it once. We only give about 1/4 of the recommended dose for his size and it seems to help alot. We cut the pills. M 3 1 years

 1  my son's allergies My 13 year old son started taking this medicine a little over a month ago and he has had mood swings and violent temper tantrums. I am not even sure if it helped his allergies. I am stopping this medicine immediately!! He is gifted and generous kid when not on this nedicine. Now he is a angry, negative brat. Hopefully, taking him off this medicine he will mellow out again and not be so mean and hurtful to all of us. I am so glad that I found this site!!! I wonder why Zrytec won't mention these side effects????!!! I have already let my son's Doctor know about this terrible reaction to this!! I will never reccomd this medicine. I am also going to contact Zyrtec regarding this side effect. No one needs to be this miserable and unhappy and angry! M 13 32 days

 1  seasonal allergies My son, now 4, has been taking zyrtec on and off for over a year. I thought he was just a difficult child and perhaps even had autistic tendencies, when I discovered the zyrtec was making my child a monster. He is an emotional wreck when he is on this medication. I'm throwing it away. M 4 1 years

 1  seasonal allergies My now 3 year old son has been on and off Zyrtec for over a year. He first began taking Zyrtec at age 2. At the time we thought that he was going through the terrible two's. Hitting, biting, temper-tantrums. Just an over all inability to control his emotions. We took him off for 2 months over the summer, we noticed how much more in control he was. We just attributed this to that fact that we was a year older and more mature. 6 days ago we started him back on the Zyrtec and within 24 hours we saw a total deterioration of his mood and behavior. He was crying uncontrollably, throwing temper-tantrums, unable to nap, and back to hitting and biting. M 3 1 days

 5  Severe Allergies Very sleepy, cranky/crabby, had a hard time staying focused on duties while at work. Wasn't sure if it was Zyrtec or Singular that was causing the sleepiness. Stopped taking Zyrtec for 1 day found that my Allergies were Severe after the last dose wore off. The sleepiness wore off though..... Took 1 dose of Zyrtec and did not take singular was very sleepy, allergies were not as severe when going off of singular since Zyrtec was in system but found that the combined use was the best and most effective for my Severe Allergies. was tired of being tired..... Then I had an idea and tried.... eatting something, taking dose of Zyrtec then going to bed. When I woke up the next morning, I was actually not sleepy like I was use to being after taking Zyrtec/Singular. My nature is normally one where it takes a litte bit to wake up, but now, after a cup of coffe (strong when asthma is really bad) I function wonderfully through out the day. I've been doing this nightly ritual of eatting a little something before bed, take Zyrtech/Singular for at least 3.5 months and I've become a highly productive individual. At work, I'm actually now doing the work of 2 people and am able to keep my head on straight with no sleepiness so that I can work on complex things and multitask at the same time. I'm so excited that I can actually do my normal duties and then some, while not being bothered with my servere allergy complicaitons. I feel like I'm a normal person for once. Try my nightly ritual and see if it works for F 36 4 months

 5  Severe Allergies responding to person with smell complications. I did have this as well - until I did my nightly ritual of eatting something, taking Zyrtec/Singular then going to bed. I now have one of the best noses around and can smell things that most people can't without any queeziness. My sense of taste hasn't really changed, at least nothing noticably. F 36 4 months

 5  allergy I suffered severe allergys this year and I went to the doctor thinking it wall a severe cold/flu. He recomended allergy medication so I tried zyrtec. It was great. Than I noticed I had lost my sense of smell and taste, so I quit taking zyrtec and instead of regaining my normal sense of smell everything smelt like I described as a strong metal smell that made me sick to my stomach. That has gotten better but everything taste the same & I can not smell. Has anyone else felt this way. F 50 4 months

 1  allergies Took Zyrtec one time and it made me psychotic. I became very suspicious, paranoid and angry. I basically went crazy and ended up punching a friend in the stomach. I later found out that my nephew had taken it once and it made him evil. F 23 1 days

 1  allergies numbness, drowsiness, anger and irritability, itchiness Sometimes zyrtec would relieve my allergy symptoms, other times it would not. I do not know if some of my side effects symptoms are due to my being miserable because of allergies, from not sleeping well, or the drug, but I DEFINITELY DO NOT want to take this drug ever again. My hands and lips feel numb and my face is itchy. I cannot concentrate or function normally because I am so drowsy and out of it. I have definite mood swings which is not like me, and I often feel angry for no apparent reason. This drug is shit. F 23 3 weeks

 1  allergies (swollen red eyes) I have been taking Zytec for over 2 years, it works GREAT, I only take a half tablet daily to control allergies. But for the last 3 months I have been at a loss at to why my hair is falling out-I've read that this may be a side effect of Zyrtec-I've stopped taking it and must put much effort into ensuring my hair grows and get healthy again. I hope that stopping Zytec will help my hair grow back because I now have red swollen eyes and less hair-lovely! F 44 2 years
