 3  9 month old taking for allergies Drowsiness at first, but now seems to make her irritable/agitated. My daughter has been on Zyrtec since she was 7 months old for allergies. Nothing else would work. Benadryl caused her to break out in hives and made her wired, she's also allergic to pseudoephedrine, and Palgic doesn't seem to do anything at all. At first, it knocked her out at bedtime. She slept soundly through the night for the first few days. But since then, she goes to bed and sleeps for about an hour, and then she's up and down constantly. She also rolls and tumbles while she's sleeping. She seems so irritable and agitated. I'm glad to hear this from other mothers. I'm going to stop it to see what happens. The only bad thing is that it has actually helped her allergies and congestion. F 32 2 months

 3  congestion and headaches I have been very sleepy, I still got headaches but fewer. I still was congested even though I didn't know how much until I went for a ct scan. It showed me fully congested in all sinuses(all areas gray). I am now on strong antibiotic with saline nasal washes with afrin(5 days of afrin) and 14 days on Augmentum 1000 mg two at am and two at pm. Now I have decided to stay off of zyrtec and I have been itchy all over my body. This happened to me another time I decided to stop for two days I was itchy all over all day long. After restarting I was ok. I am not sure what happened since I've been on zyrtec for 3 years thinking it was helping me. This itchiness has never been mentioned as a side effect for stopping the zyrtec. Are there many others experiencing this. All I know is that I will never resume with zyrtec again, knowing that I will be itchy if I stop. It's not worth it. I have to find something else??? F 54 3 days

 1  mild to moderate hive on hands After one dose of zyrtec-d I felt like spiders were crawling on me. Had a massive hive outbreak all over, esp. my face and neck. Took 2 days to abate (before my hives lasted just an hour or two). Became extremely senstive to cold (fan blowing on me from car A/C caused huge mottled red rash on my arm and neck for three hours. My doctor did NOT warn me of any side affects. I'm going back to Claritin and benadryl. They didn't work perfectly, but were good enough. It's ironic that the medicine I took to stop the hives made them a hundred times worse. F 32 2 days

 1  baby measles My 2 1/2 year old son was given this medication by his Doctor for any itching that was associated with the rash he had from the baby measles (Roseola). I gave him 1/2 tsp one time. It literally turned into the devil. He screamed and cried for no reason. He had violent outbursts where he would try to hit at us. I couldn't believe that my toddler was acting like this. That this medicine could actually change his behavior in such a way the it scared the crap out of me. He would just start 'freaking out' and then he would be saying 'Hey Momma' and smile at me. Does anyone remember the 'EXORCIST'??? I do not recommend this drug for children of this age. I will stick with Benadryl. M 2 1 days

 4  Allergies The first few months I had had no side effects. I needed Zyrtec everday though for my severe allergies and it worked like a dream. However, recently I had been having violent dreams, depression, and weight gain. I have not changed my diet and I exercise for about 90 minutes a day. I am on no other medication. However the Zyrtec really does help with my allergies. F 18 1 years

 1  For allergies, hives Was taking for seasonal allergies and hives of unknown causes on my hands/wrists. After taking Zyrtec my entire body broke out in a bad case of hives. The same thing happens for me with Allegra. Now I am scared to try anything else! I used to take it and it was fabulous. Maybe something in my system changed to make me react so strongly to it? F 30 1 days

 3  Allergies - seasonal and pet My son (now 12) has been taking zyrtec for about 4 years. It completely took care of all of his allergies; however, he has become increasingly angry and has temper tantrums...yes, at the age of 12!!! Not a pretty sight and also happens at school. He is a gifted child and has never had any behavioral problems until being on zyrtec. We never experienced this before and I am so glad I found this site because after reading all of the comments, I see a definite common demoninator among children who take zyrtec and that is anger. I must find something else immediately. I wish I had known this BEFORE as it will be very difficlt to find a medication that will do all that zyrtec has done WITHOUT causing anger and violent behavior. M 12 4 years

 2  Allergies This medication made me so drowsy that I couldn't function during the day. I would stumble around almost in a trance. It helped my allergies to a degree, but the extreme drowsiness it causes isn't worth it. F 20 5 days

 5  Allergies Just very tired all the time. I take it at night. When I miss 2 doses I get very itchy and my hands and feet burn. It's bad enough to wake me up at night. I am trying to wean myself off of it. I'm glad to hear that others have the same effect when they stop taking it...I'm not crazy!! I'll have to clue my doctor in. F 34 2 years

 1  Sneezing, swollen itchy eyes My ped gave this to my 20 month old son for his allergies. He turned into a uncontrollable child. Screaming, having temper tantrums, kicking, hitting. I thought, Oh no terrible twos are going to be horrible. We took him off of it and he is back to a normal 2 year old. I do not recommend this at all. F 35 3 weeks

 5  Allergies None I have taken Zyrtec intermittently for almost seven years now and have never had a problem w/it. It does its job (dries my sinuses and allows me to move away from the tissue box) and has never caused any noticeable side effects. F 23 7 years

 2  allergies My 3 yr old became a different person, yelling, biting, spitting, throwing things, and agitated by the 2nd day. Called doctor and they weren't even surprised! Suggested I try Claritin, but said it might do the same thing. Zyrtec cleared up the allergies quickly, but, I'd rather have my runny nosed angel than the clean faced, unpredictable stranger on Zyrtec. F 3 2 days

 1  seasonal / pet allergies Dizzeyness, Confusion, Out of it feeling. SCARY irregular hartbeats, laziness, cough, I was given the perscription about 2 months ago for trial because of severy allergies at the start of pollen season. It worked great at first and still does. I just started to notice Im not myself all the time. I turned into evil kenivel on the highway and no logical sense while doing it. I go through mood swings that dip real low to the point of why not just end it now. I have never been or have i ever experienced such crazy thoughts. I keep gaining weight although I have no appetite. I don't even eat that much yet can't loose a pound. 175lbs. for reference. Was usually 165-170. The past couple days I took myself of cause I just figured I was falling apart cause of zyrtec. Anything that makes your heart feel anyother way than normal is no good. DO NOT TAKE IT! M 30 2 months

 1  seasonal allergies severe fatigue, drowsiness, dissociation or dream-like state, flat effect I took Claritin before but had no relief, so I began Zyrtec a few years ago on and off. It'd work, but my allergies weren't bad enough to be bothered. This year they're terrible, and noticing Zyrtec is making me almost completely incapacitated. I take it before bed because it leaves me so tired, but I wind up sleeping 10 hours and extremely tired the next day, with a strange disconnected feeling. I've been told I seem to not know what's going on around me and have no emotional reactions like I normally do. It however, does make my allergy symptoms go away, but I'd advise anyone to stay far away from this especially if they find out of body/confusion experiences scary. (p.s. I've been using it 3 yrs but it's on & off and only in the spring) F 22 3 years
