 2  Seasonal Allergies I am super tired all the time, I took a nap the 2nd day for about 3 hrs and still felt lazy and tired afterwards. I get so hungry throughout the day. It helped very little as far as my dust/pollen allergies. Spring 2007 in MD. I still sneezed, runny nose, itchy eyes, etc after taking the pill. I took the pill at 8PM before I went to bed. After reading these comments I finally found the answer why i've been feeling/acting so differently. I knew it was the pill! Time to find a new allergy medicine. I don't like it at all M 22 4 days

 3  allergies feeling irritable. Not much energy. noticed a weight gain after just over a month. Watching what I am eating and walking several times a week for several miles has not helped. My feet and hands are swelling at times as if retaining water. Allergy problems have been better but I didnt have any of these side effects with Allegra D. After finding this site and that many others have had similar problems and horrible withdraw issues I am off it! F 40 55 days

 2  Constant Sinus Problems Wow this was eye opening. I was just lying in bed wondering what the heck was wrong with me! I even had my doctor set me up for blood work because I could sleep ALL day long. I have no energy and am PMSing all the time. This is all very unusual for me and was driving me crazy, until I read this. To boot, I still have PND, cough, etc....didn't seem to do much, but make me tired and irritable. Thank you all for posting! F 41 7 days

 2  year round allergies My 7 year old has been on Zyrtec for 4 months. What I had started to think of as behavioral problems might very well be attributed to this drug....He has become angry, depressed, out of control, incredibly aggressive and argumentative. I did not know people were having these kinds of side effects so I would never have suspected his behavior and nightmares could be caused by this so called miracle drug. Also, these behaviors did not appear immediately upon starting Zyrtec, it has been more of a steady increase and intensity of symptoms. I read parts of this site last night and decided not to give him his dose. He used Claritin instead--it actually dried up his eyes, something zyrtec had failed to do. I was not 100% satisfied with zyrtec even before I found out about all of these other unexpected possible side effects. It did nothing for his runny nose and eyes but did seem to decrease the frequency of the "flare-ups". F 36 4 months

 1  Allergies My 8 yr old son was on zyrtec for about a week for allergies but when the allergies eased up i stopped the zyrtec because i figure why take meds when you dont need them. Anyways his allergies are acting up again and so are his sisters so the doc told me yesterday to give her the zyrtec now also. For some reason I had a hunch to look it up on the internet and I came across this site..OH MY GOODNESS I am so thankful I found this page. Needless to say the Zyrtec went bye-byes and they both had benadryl before they went to bed last night. I will NOT give my kids zyrtec if the side effects are that bad. I had no clue because my son had only taken it for a week before i took him off it the first time. I wouldnt have noticed any side effects in that short amount of time.. THANK you to everyone on here for sharing your horrible stories. Now my kids wont have to go through hell! F 33 7 days

 3  Seasonal Allergies My 6yr old daughter had problems last spring with vaginal irritation and discomfort when urinating. We took her to the pediatrician 3 x's and a Gyn and they came up with nothing. This spring, same problem - went online and found this site stating some females had similar problems w/Claritan. I called Pfizer this morning and they told me that skin irritation is side effect of med(which they included her problem as part of that side effect). Incidentally, 4 yr old son had strange rash on face after starting Zyrtec, maybe is related to med as well? My daughter has terrible allergies, don't know what to do to relieve suffering - she missed several days of school last year due to vaginal irritation - not to mention Dr's asking her if anyone "touched" her. Terrible experience for parent! F 6 30 days

 1  Allergies After only 5 days - Depression, total loss of self-worth, crying spells, loss of motivation. It took me 9 days and this site to realize it was the medicine. Depression is not listed as a possible side effect, but two weeks ago I was fine and now all I want to do is cry for NO REASON! Hopefully this med will be out of my system soon! F 45 9 days

 3  seasonal spring allergies I just googled zyrtec and light sensitivity b/c I have been terribly light sensitive lately and wondered if that was a side effect. I also have a corneal disease and so was wondering that something had changed with my corneas. I am relieved to learn that this possibly just due to the antihistamine. I am going to try going off it now to see if that helps, although it does seem to help with the allergies. But I'll find another way to deal with that, since right now I don't want to go outside during the day...and I live in Southern California!) F 30 15 days

 5  zyrtec HEADACHES FROM HELLLLLLLLLL! Due to my Angioedema and hives I was put on 10 mg. of Zyrtec...awesome as for completely getting rid of the hives, however slight swelling currently in the upper left cheek. I was also put on Nasonex twice a day. I stopped the Zyrtec 2 days ago until I read these blogs and realized what the issue was. I had to wean myself off of it and did not due to the BAD headache and frustration. I just took half a pill and I am already feeling relief after about 25 minutes. Thank you to everyone for taking the time to write their own personal experiences, it's NOW helped me! GOOD LUCK!!!! 40 2 days

 1  allergies My sons took this for allergies, ages 4 and 5, with bad dreams and restless sleep as a result. Also my 5 year old had daytime hallucinations, asked if he was dreaming, said he saw things that we didn't, it was really weird. I would not give this to children unless their allergies were unbearable. I would rather treat with Vicks Vaporub at night than have a wigged out child. M 5 3 months

 1  Allergies Took with Avelox - major hypnotic effect. After Avelox kept taking - kept being very very dizzy - esp. when lying down. Stopped Zyrtec 6 days ago. Good news not dizzy at all anymore! But ITCHY. At first got very itchy palms and skin with red rash. Also eyes very itchy. Taking Benadryl at night now (can't take during day as it makes me too sleepy). Itch better but still there. Hope it goes away. I would not rec this drug to anyone. Side effects too serious. Esp. do not combine with Avelox! F 53 60 days

 2  Seasonal Allergies My 4 year old son is allergic to almost everything under the sun having to do with outside and springtime. About a year and a half ago we took him to an allergist and he was tested and prescribed Zyrtec to treat his symptoms. He has been on and off of this since. About a 2 weeks ago he began to have allergy symptoms. So I administered the Zyrtec. About a week or so after that I noticed that he began to move his neck, clear his throat often, blink plenty and shrug his shoulders involuntarily. When I took him to his pediatrician she freaked me out by likening his symptom to a child with Tourettes said that they were repetitive tics and referred us to a neurologist. I lost my mind, but it wasn't until I began to read these ratings and came across one that talked about the involuntary tics that I made the connection and did some more research on the medication. Do not let your pediatrician diagnose your child with a trumped up biased observation and call it "tourettes" when in actuality it may only be the medicine. This scared my husband and I to death.

 4  hives induced by allergy to latex Weight gain and extreme increase in appetite For months now i have been trying to figure out why i have been putting on weight and why i am so tired! I have only gained about 6 pounds but that is alot for me because i used to have a very fast metabolism and never had cravings. Now i am ALWAYS hungry and can't go as long as i used to in the gym. My hives were crazy and they would last for days until i took a zyrtec pill, at which point it would provide me with immediate relief- i even used to call it a miracle drug. It truely is amazing how effective it is for allergies but the way i am becomming i almost prefer the itching and swelling :( No more zyrtec for me :( F 23

 2   The strangest and most vivid dreams that I have ever had. It makes me feel paranoid and angry. It makes my skin feel like there's sand underneath it. I feel like the guy from The Shining but my allergies are so bad that I'm not sure what to do. M 28 1 months

 1  Severe allergies Mood swings, weight gain, dizzyness, lightheaded, disconnected, upset stomach, tired all the time, lack of motivation. I will never take this again! I was on it because Claritin wasn't working anymore. Once I stopped taking it I started getting eczema all over my neck and lower part of my face. I have never had eczema. My personality and moods did a complete 360 on this medication and I didn't realize it was the Zyrtec until my fiance ask me to stop taking it for a week. F 24 1 months

 1  allergies visual, auditory and tactile hallucinations My 9 year old son was on Zyrtec for 7 months. When placed on Amoxicillan for two weeks for a sinus infection, he began to experience hallucinations. The doctor thought it might be the penicillan and never mentioned the zyrtec. Had an EEG which was normal. When I realized the side effects of zyrtec I took him off immediately (5 days ago). However, he just had an "episode" again tonight (lasts about 10 minutes). Has anyone had a child experience this??? How long before the side effects go away? M 9 7 months

 4  Extreme tree pollen allergies While this medicine makes me a bit drowsy,it's far better than suffering with my very extreme pollen allergies. Claritin does nothing for me. Zyrtec is the only thing that makes spring bearable. The people who are complaining in this forum of side effects probably do not have the level of allergy that really necessitates a drug like this. Make sure you see a good allergist who can give you a prescription that suits you! I've been taking the drug for the last two springs, on a daily basis throughout the season. I also occasionally take allegra or a nasal spray with it, as needed. F 25 2 years

 2  nasal allergies year round I had noticed my mood change drastically. I felt like I was PMSing all month long. EVERYTHING got to me. I was in a rage over any little thing. I am normally not like this at all! I tested to see if it was the zyrtec (stopped, symptom went away, started again, symptoms started, and so on). Went back to Claritin and am fine...for now. The same symptom was with my 4 year old. His pediatritian prescribed it for him and I trusted it was ok. Immediately had to stop. My son changed overnight! should mention this side effect in their product labeling F 35 3 months
