Okay I need some help from all you people. I have been on Zyrtc and Singulair for about 10+ years. This past Monday was my last pill for both. Tues and Wed did pretty well. Thursday and Friday not so much. I can handle the sneezing and watery eyes what I can not handle is the ITCHING!!! Driving me crazy. That started about 3 this afternoon. My doctor does not want me to take any antihistamine. How long is the withdrawal take from these meds? Any suggestions or advice would be greatly appreciated

I wish I had found this site a year ago. My 9 year old son was prescribed Zyrtec for his nasal allergies. He took it each day for over 6 months. He began to have problems in school - withdrawing from class participation, moody behavior at home, depression, lethargy, anxiety, worry, feelings of despair, told me that he would be better off dead! I started to panic but never associated the Zyrtec with his mental state. Took him to a counselor who said that he seemed like a normal, well-adjusted little boy who was sensitive. Realized that the Zyrtec was not really fully controlling his nasal allergies so decided to stop taking it for a while. Not much change in the allergies but the emotional change was amazing! I had my little boy back in only a few days after stopping the Zyrtec. First thing I noticed was that he was no longer mopey and lethargic and wondered if the Zyrtec had been making him tired. Then when the rest of his emotional issues disappeared magically I began to suspect the Zyrtec but the ped. dismissed my fears. A few months later he began to have bad allergies again so again tried an anithistimine for him. Zombie-like state returned right away. For some reason he is hyper-sensitive to all anithistimines and we avoid them all with him. What I learned from this is that doctors are not open to admitting that these drugs they so casually prescribe have serious side-effects.

Went to the doc's with a bad deep cough had for about a week. I was prescribed an antibiotic, eye drop, and an antihistamine. Went to local drug store found out insurance would not pay for antihistamine because it was the same thing as OTC Zyrtec and that the drug store had a generic brand which was cheaper. Started taking it on a fri. night all went well until the following Thur. night at work. Arrived at work normal time then roughly one hour into my shift I notice sweating, dizzy, and not aware of my surroundings, when suddenly I found myself passed out on a hard concrete floor flopping like a fish out of water. Taken to ER were they performed CAT scan, MRI, and very painful spinal tap.
All came back clear. After a stay in the hospital fri I was looking forward to being discharged sat morning when all of sudden it happen once again. In fact it happen three times sat. What was it you ask? My heart had STOPPED first time 5 seconds, second time 11 seconds, and the third time with my Wife watching my heart stopped for a full 18 seconds. Awoke to the sights of several Nurse's with difb in hand ready to shock me back. Rushed to ICU my heart than began racing to 170 – 180 beats a min. had to get med’s. to slow it down. Was schd for a pace maker. Final diagnosis ZYRTEC! The hospital Doc., Cardiologist as well as my PCP agreed.

I think the hardest part - for me - was even to concieve the idea that Zyrtec has all of these side effects.

I've been taking Zyrtec on a daily basis for about 90- 110 days a year due to really bad allergies. We live in the NY area which produce alergans most of the year.

After trying almost every antihistamine, Zyrtec seemed at the time as the best drug since it handled the allergy while eliminating the drowsiness almost completely for me. Being happy that I was able to maintain normal life during allergy periods was almost a new concept for me and I was really grateful for finding this drug.

Unfortunately, being almost blinded by the allergy-fighting success, I neglected the attention to the side effects. I guess I'm falling into the unlucky 2%. I had almost every side effect: Irritation, mood swings, gaining weight, dry mouth - just name it.

Recently, my wife did some research because we got to the point where I would fight with her over anything. I can testify that my tolerance level hit the ground. Anyway, she got my attention for her research results which turned a red flag for me. In addition, this year my body seemed to not respond anymore to the drug and doing my own little research revealed that it is very likely that you need to rotate different drugs every few months.

So I decided to get off Zyrtec and switched to Benadryl Allergy which I take every 4-6 hours. Yes, it does make me drowsy for about 15-20 minutes but it works. What's more interesting is, I've been about 10 days off Zyrtec and I am shocked to realize that I'm slowly getting rid of all the side effects associated with Zyrtec.

That being said, I would like to emphasize that this was my own individual experience and it may not be the same for someone else. But it is pretty disappointing for me that i cannot use this drug anymore on a regular basis.

I started using Zyrtec recently after my niece received it from her doctor as the solution to her allergies. (We bought it at the drug store). My allergies are skin related where i walk and feel a deep itch in my thighs and anywhere else i have tight clothing. Also when i work out - i have itch deep skin. This is under the surface and very uncomfortable especially when you are walking/working out. Leads to confusion etc. I had never used any allergy medicine before but decided just to see if i would feel any different.

Anyhow, I started using Zyrtec the other day and almost immediately, I started fighting with my boyfriend - everything i was angry with him about came out. It was helpful but also i was very mean in my approach. I also started getting back pains around the spine area - not in the spine but around it and could not sleep until i took an ibuprofen. Today i experienced left shoulder and back pain. That was it for me and whats funny is that i took the lowest possible doze. So i am not touching that medicine again. I am a 36 year old woman. Its a strong medicine and something is strange with it (changes moods etc). I will have to change the medication for my niece before she goes through the side effects.

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.

I have no such symptoms with Zyrtec-as a matter of fact it is about the only antihistamine that works for me. I have been back on it for about three months and the only reason I was off it for a while was because the VA did not have it in their formulary so I was put on Loratidine which did not help me much for my allergies.
