 1  allergies Have developed a dependency. If I miss a day, by that evening (36 hours after taking last dose), my skin feels like it's crawling and it's a miserable, itchy evening. As soon as I take even 5 mg, the itching stops within 1 hour. Looks like this is a common issue. It's the only thing that has seemed to work for eczema and allergies, but it's NOT worth the addiction! I've successfully gotten my kids off the medication, but I am still dependent on it.

 5  seaonal allergies, digestive issues Was told to have my son take it at night, just in case it made him drowsy, but we didn't notice any increase in drowsiness. Zyrtec was wonderful for our son. He went from having 2+ weeks of unbelievably runny noses every time he caught a cold, to just normal symptoms of a few days. He also felt a great lift to the almost constant depression he had been feeling, and it cleared up the gastro issues he had been having as well. We took him off Zyrtec and put him on Claritin and it just didn't do the job. I see a lot of negatives on here about Zyrtec, but for our son, it made such a positive difference in his life.

 1  seasonal allergies I have taken Zyrtec probably for about 9 yrs. I took other allergy medicines before that. I have had seasonal allergies for about 35 yrs. As I get older I have found that I am tired all the time and have no energy to exercise. I have tried going off Zyrtec before during the winter months but always have the itching that gets worse with each day I'm without Zyrtec so I usually start it again. But after reading all these testimonials, I am going off it for good. It's been 4 days since I took Zyrtec and I am feeling flu symptoms. I just feel really weird and have a sore throat. I don't know if this is from not having the Zyrtec or if I really do have flu symptoms (I haven't felt right for 2-3 days) and its not getting any better. Has anyone had these symptoms when going off Zyrtec? The itching hasn't started yet. Had I know that Zyrtec was addictive - I would not have started it! My doctor never told me! F 56 9 years

 1  Seasonal Allergies I take a 24/hr zyrtec every day. If I 'skip' a dose I can't go more than an hour or two before my hands and feet begin itching. It then spreads to my head, legs/arms. It's so intense my only option is to take another zyrtec. My wife has taken the same dose for about the same length of time and has the same symptoms. Zyrtec definitely helped my allergies but the withdraw symptoms are not only undocumented but seemingly impossible to overcome. M 32 4 years

 1  allergies sleep problems, fast heartbeat and most recently night terrors after stopping dosage for 2 days My recent allergy episode was so bad that I took Zyrtec and continued to take it for about 5 days. When the allergies got better, I stopped taking the drug. I woke up drowsy, sleepy and very irritable this morning. An hour later, after sending my son off to school, went for a nap and woke up 6 hours later from an upsetting dream. I was sluggish throughout the afternoon and early evening. Finally went to bed and shortly afterward began having night terrors for the first time in my life! I couldn't breath, felt paralized and had to lay there until I calmed down. Will not recommend this to anyone especially children. But for parents whose children are on this medication, I would suggest contacting a doctor as stopping the drug IMMEDIATELY HAS ITS OWN SIDE EFFECTS. Good luck. F 41 5 days

 1  severe allergies to grass and trees My 14 year old son became a completely different person - formerly happy, cheerful kid turned severely angry, moody and suicidal. Also developed skin rashes. Didn't appear to help his nose symptoms either My son took this drug haphazardly which is probably the thing that saved him. He took it most regularly when he started going in for his allergy shots every Friday. Then every weekend he was a depressed mess. Looked up ways to commit suicide on the internet. We started to wonder if it was the allergy shots and then made the link to zyrtec. He was off it for two weeks and became more normal. Two days back on it, suicidal again. I don't think this drug is appropriate for children!!!!!!! F 48 4 months

 1  allergies Anger, tiredness, lack of appetite, night terrors I have just tipped my bottle down the sink!! My 3 year old was on this off and on during the spring for allergies. While it helped with the allergies it turned my wee man into a tantrum throwing brat. The worst part was he ended up having night terrors and it would take hours to calm him down, never again!!

 4  allergies I took zyrtec for about a year and a half. Loved it. However, Ive had to stop taking it to have some allergy tests taken. I was violently sick to my stomach, have headaches and now cant have an empty stomach. I can only hope these symptoms go away as my activities have been SEVERLY limited. F 58

 3  Year round allergies If it was the zyrtec, as my new allergist claimed, extreme lethargy, dizziness, foggy thinking, never able to fully wake up, worse depression, ADD and anxiety. Never related these symptoms to zyrtec. I was happy that my allergy symptoms were better (never fully gone, but better than any other med) that when Dr's would suggest getting off of zyrtec b/c of lethargy/complete tiredness, I told them they were crazy; My allergies would go nuts. But now I've been off of it for 3 days and feel so much better. Almost human right now. Symptoms got worse every year I was on it. I just assumed my allergies were worse every year as I heard others in this area talk about. F 42 12 years

 4  Allergies tiredness, dry mouth and eyes, irritable, some dizzyness I really like this product. If I don't take it early enough at night, like before 8, it will make me tired in the morning. If I take it during the day and I get very relaxed, it will make me fall asleep. Sometimes my eyes get dry and my contacts stick to my eyes so I have to be careful about that. I do get dizzy, irritable and have heart palps and I'm not sure if Zyrtec is contributing to this. It might just be anxiety. I can't take more that 1/2 tablet or it will make me very sleepy. It's not a fast acting antihistamine so if you need something fast you might try chlortab or benadryl. I take the zyrtec as a last resort if I can't get the darn sneezing to stop or if my eyes start itching. It has strong sedative qualities so take before bed time. F 41 4 years

 4  Allergies and Asthma None that I have noticed, although I do take it just before I go to bed, so I'm really unable to tell if it may cause any drowsiness. I have moderate allergies year round, but I am severely allergic to cats. I have recently moved into a house with three cats. For awhile I was taking other allergy pills that were working okay,but I had to take them more frequently, and I was still suffering a lot of symptoms. When I began to take Zyrtec 24 hour, Nearly every one of my symptoms were reduced greatly. Before, living with cats was nearly unbearable, with the itching, sneezing, watery eyes, inability to breathe, etc. Now, I can even play with the cats and I feel fine. Just a little bit of itching still occurs, and my nose isn't always perfectly clear. One day I went just over my 24 hour limit to see what would happen, and my allergic reactions came back with a vengence, so this medicine might have to be a full time thing for me, but it's better than my other options.

 2  allergies making my voice raspy extreme tiredness, yawning all day (needing a nap right after I woke up),inability to focus at work,lack of energy I started Zyrtec at the suggestion of my doctor because I was having relatively mild allergies that were affecting my voice. I think it helped the allergies, but I have been so tired, I can barely function. Like some others, I am so glad I found this website because my doctor did not tell me/think it could be this medicine. But based on when the symptoms started, I know that this is the culprit because I am usually a very energetic person. Didn't have the negative emotions, but who knows, maybe I would have had I continued. Thanks for posting everyone. Going off--the "cure" is way worse than the "disease". F 48 20 days

 1  Moderate seasonal allergies Heart palpitations, dizziness, itching when I stopped taking it. I only started getting allergies about 4 years ago. Most of the time the symptoms are pretty mild. My doctor recommended Zyrtec and I would take it for 2-3 days at a time when my symptoms were intolerable. 5 weeks ago I started having bad dizzy spells and hives and my doctor diagnosed allergies and said that since I was so out of it I needed to take the Zyrtec until they cleared up. The dizzy spells went away after about a week. I would take the drug for several days and then skip a day to see if the allergies had gone away yet. Every time, I started itching again, so I thought the allergen was still around and went back on the drug. Several days ago, the dizzy spells came back along with a pounding heart that would last for hours. I'm very fit and physically active so this seemed really weird. Went back to my doctor who told me that palpitations and dizziness could both be side effects of Zyrtec and gave me a new prescription. I didn't even try the new prescription but my dizzy spells are gone already so I assume this bout of allergies is over. My heart rate is also getting closer to normal. I do still have a little itching, but looking at what everyone else has to say, I'm now convinced that this is due to stopping the Zyrtec and not to an allergy. F 38 5 weeks

 4  Allergy induced asthma I am pregnant so it is hard to know, I have been tired but it could just be pregnancy. I had a cold in June that I could not get over. I had an extreme cough that kept me up all night. Around this time I also became pregnant. Doc. gave me prednisone 1wk and I felt better and also an albuterol inhaler telling me I suddenly had asthma. I was okay for a month but the cough never really left. I still coughed a lot during the day and often needed albuterol before bed (although it made me jittery). I started needing the inhaler 3 times a day. He prescribed prednisone for 1wk and daily use of Flovent Diskus. I was feeling pretty good and did not need albuterol. After 2wk sample ran out I went to pharmacy and found it was $96/mo. after insurance. I looked up alternatives and found it was category C risk during pregnancy (more experimental than most drugs). Went to my OBGYN and he suggested Zyrtec (only cat. B). I have been on it almost a month and have only used my albuterol once (when I had taken my dose late). I do get a little congestion in the morning which is normal for me and common for pregnant women. I have a productive cough and it is gone before I'm up and about for the day. I am sleeping much better at night and am overall much better off, although Flovent worked too, I feel better about the lower risk. F 28 1 months

 1  asthma, wheezing, hives My 2 y/o son is taking Zyrtec at advice of allergist. We tried Singular, but he had anger side effects with that medication. Since starting Zyrtec, my son has gone from sweet boy to anger-man. He hits himself, he throws things, he constantly says, "I can't, I can't!" He woke up last night screaming in fright (hasn't done that in over a year). He's just so negative. After reading comments here, I'm taking him off. As an aside, I had chronic idiopathic urticaria when I was younger (still comes back every now and then). To keep it under control, I took a combo of Tagamet (yes, the stomach acid medicine) and Claritin. My doctor said there is a secondary ingredient in Tagamet that works like Benadryl, but without the sleepy side effects. It might be worth discussing with your doctor if you are trying to find a non-itch solution. M 2 3 weeks

 1  allergies (cats, dust, ragweed) exhaustion, feeling wiped-out, nightmares, irritability, unexplained anger, weight gain, difficult swallowing, thick congestion I have never felt so exhausted. I took 5 or 10mg at night and on weekends I easily slept until 5pm. On weekdays I could barely get out of bed, let alone hold my head up at work. I just couldn't get enough sleep. I found myself so irritable, even enraged, didn't feel like myself at all. Yet, nothing "bad" had happened in my life. My allergist thought I was crazy during the 30 day check-in when I explained the exhaustion and crazy dreams, etc. I am going back to Alavert where I have no side effects. F 32 35 days

 1  allergies Always felt exhausted. Generally, everything seemed overwhelming. Decided to stop taking zyrtec this week because I was tired of feeling exhausted all of the time. Could not wake up in the morning. After 4 days without zyrtec, I felt much better, but now I am experiencing itching all over. I guess zyrtec prevented this itching, but I am not sure it was worth it. Looking for another solution. F 56 3 years
