Zyrtec and withdrawal symptoms

My 4 1/2 yo daughter has SEVERE allergies since 6 weeks old. Our specialist prescribed Zyrtec and she has been taking it every night for 3 1/2 years. We haven't noticed any obvious side effects as others have. She is certainly not drowsy (in fact the opposite!)A couple of times we have run out and she has missed it for 1-2 nights, and she has started itching ALL night. We have assumed that she needed the Zyrtec and rushed out and bought more. As I am getting concerned about the long term effects, started researching and found this site. Maybe we should consider that this was withdrawal symptoms and not the allergies. Does anyone know how long the withdrawals last? Thanks to all the posts for all the relevant information.

My personal experience with Zyrtec was so awful that I decided to document it in a blog in great detail to try and help other people: http://zyrtecsideeffects.blogspot.com/

I suffered severe depression, menstrual problems and other health issues whilst on Zyrtec. The depression literally disappeared overnight when I stopped taking Zyrtec. I suffered horrific withdrawal symptoms for 6-7 weeks after stopping Zyrtec which I have documented in my blog.

My husband suffered for a full year with constant burping--not reflux, not heartburn, just air, like colic. He was so bloated that it was painful for him to sit. He went from doctor to doctor, and even to a GI who suspected Celiac's. He also had a feeling that his throat was constricted, and once went to the emergency room, afraid that it might close up. The doctors found nothing.

He has a severe dust allergy (it causes hives, no respiratory symptoms) that was diagnosed last year, at which point he was prescribed Zyrtec and Singulair. He mentioned the prescriptions to every doctor he saw (this is in New York, not the boondocks, btw), and every one said it can't be the Zyrtec or the Singulair. It should be noted that we eat all natural foods, no white flour, no white sugar, so we knew there were no artificial additives that could be causing his reaction. My husband even tried cutting out dairy, then wheat, then all gluten, for over a month.

Finally, about five weeks ago, he told a cousin about his mysterious symptoms, and she asked if he was taking Zyrtec. He said yes, and she said he should try going off it because she'd had a similar problem with that drug. He did, and within four days, the burping and bloating stopped.

Because his itching was uncontrollable with Singulair alone, he decided to try taking one Zyrtec, thinking it might not hurt. Within 24 hours, the burping and throat swelling was back intensely.

The doctor switched him to Allegra. He took one and it helped him. He took a second pill two days later, and the burping reaction started. The allergist confirmed that people who have this "rare" reaction to Zyrtec may also have that reaction to Allegra.

If you are suffering from these symptoms, go off the Zyrtec as soon as you can. I wish someone had told us so that my husband would have saved himself a year of suffering.

I was prescribed Zyrtec a few years ago for allergies. I also have MPV and need to take Atenolol, I will need to take Atenolol for the rest of my life. My cardiologist recommended I stop taking Zyrtec because it can give you an irregular heart beat. When I tried to stop it I got very bad withdrawal symptoms, chills,heart racing, insomnia, itchy skin. I thought I was going crazy, so I took one Zyrtec as soon as I took it 15 min later the symptoms stopped. The next night I decided to try and cut the pill in half and only take 5 mg, that was ok for 3 day's then the symptoms returned. I had to take the other half of the Zyrtec and then the symptoms went away.
I can not believe that I have to find a way to wean off Zyrtec. I am very annoyed that they do not list on the label that their could be withdrawal symptoms after taking Zyrtec for a while. I am not giving up I am going to continue and try to wean myself off the Zyrtec, hopefully I won't have a heart attack in my attempt to get off this drug. If anyone has a successful way to wean off Zyrtec please post it. Thanks and I hope this helped someone who was thinking of taking this drug. STAY AWAY FROM IT..

I am trying to get off Zyrtec after having taken it for the last four months. I am having a hard time doing so. I've taken Zyrtec every spring for about 10 years. Every time I go off of it I develop terrible insomnia. It takes about three months to get over the insomnia. BUT this time around, I have developed a terrible itching. The itching goes away if I take one-half of a Zyrtec pill. It comes back if I don't take another pill within 24 hours. Come to think of it, I have developed this itching before when I went off Zyrtec and used hydrocortisone cream to stop it, but I never before contributed the itching to the Zyrtec. It is definitely some type of withdrawal symptom.
Also, my husband has noticed that I get terribly moody, depressed, cry a lot, and become critical of everyone when I am on Zyrtec -- and go back to my normal self when I am off of it.
AND I have begun to notice that my appetite goes wild while on Zyrtec. When I go off Zyrtec, my appetite goes back to normal. I have gained almost 50 lbs since I was introduced to Zyrtec.
I would like to say that I will never take it again, but it is the only antihistamine that completely controls my springtime allergic asthma. I need to be able to breathe.
