Zyrtec and depression

My 13 year old son was taking Singulair for several years and had developed, over time, depression and anxiety. I didn't put the two together until the news stories came out a couple of years ago. Since then he has been taking Zyrtec. Over time the depression and anxiety has returned. He does not take the Zyrtec everyday, just as needed. I believe that it has built up in his system to cause the side effects. Can anyone give me an idea of how long it takes to get out of his system so that I can tell if this is what is causing the problems or if I should look for some other cause.
Thanks

Wow! My husband and I have thought recently maybe I should stop using Zyrtec. Maybe it is causing my lethargy, weight gain, difficulty sleeping, inability to work for more than an hour doing anything, intense hunger. I have taken Zyrtec year round for several years since living in Santa Fe where I developed bad allergies. There I took it in conjunction with Nasonex. After leaving there I couldn't afford it so I switched to day hist but I started sneezing and had an itchy nose constantly. Sinus infections also. So I started Zyrtec full time a few years ago. I can't lose weight to save my life and have no energy. Depression-yes. I would never have thought I would experience that. My journals are full of it. But I thought it all was because of "the change" because I was under the impression there weren't any side effects. But I am all organic and still struggling with trying not to gain anymore weight. I have a terrible time just trying to clean one room without feeling wasted! I don't look forward to stopping but I have got to see if this is affecting me this way, Thanks to all. I want me back!

I just found out about the hives issue when going off Zyrtec. The incredibly annoying thing about this is that the reason I went on the Zyrtec is because of hives so now that I'm trying to see if my hives are gone by going off the drug I can't tell because that's the withdrawal symptom! I used to have to take up to TWO pills a day to deal with my hives and now I can go about three days since I started using traditional Chinese herbs (through a practitioner) to work on my hive issues. Part of me thinks that the herbs are working but it's impossible to know because of the withdrawal issues. I would not have taken this drug for hives if I had known that was what would keep me from being able to stop taking it. I'm really aggravated!

I began taking Zyrtec 2 months ago. It controlled my allergy symptoms very well, but I noticed increasing fatigue and depression. I became a "couch potato" barely able to get through my day. I began having suicidal thoughts and gained weight...probably due to the lack of activity. In the last 2 days, I have gone back to my old allergy medicine (Allegra) and am feeling like myself again.

Has anyone experienced Zyrtec withdrawal? I've been taking Zyrtec for at least 4 years and whenever I try to quit I develop hives, stomach pains, and it becomes difficult to breathe. I want to try and quit for good, but it will be difficult.

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.

I have allergies to dust mites, and started taking Zyrtec to help get over a sinus infection. It worked great at first. Then I started to feel not myself, and my thoughts were out of control. I have depression, and it magnified it. I stopped taking it, and started taking Claritin, which made me feel speedy and gave me heart palpitations.

I had been somewhat depressed for a while. After 2 days of being on Zyrtec, I was nearly suicidal. I continued to take it for a few more days because it did help with my allergies. I wasn't sure that it had anything to do with my depression until I stopped using it (after a week). Being off of it for 2 days changed my complete outlook on life. I am much happier and positive. I only tried Zyrtec because my insurance company refused to pay for Allegra, which works very well with no side effects.

My son is in second grade and has been on Zyrtec and singular since he was four years old. He was diagnosed with asthma and peanut and tree nut allergies. He has always been the sweetest kid. However, we noticed in first grade that he was spacing out and not always focused. he became easily frustrated, did not want to do his homework, cried for everything and gave up easily. This year in second grade we are noticing the same thing in addition to talking back, being aggressive with his brother, rolling his eyes and having a nasty disposition. He is negative and complains a lot. His grades have been suffering greatly. He rushes through his school work and does not pay attention or try.
I am so happy for the reading that I am seeing on this site. My son is coming off the singulair and the Zyrtec first thing in the morning.

My son was on a cocktail of Singulair, Zyrtec, Astellin and Nasonex. Like a miracle, his severe allergies cleared up almost immediately. Months later, behavioral changes started to surface. Extreme irritability, major meltdowns over nothing, problems in school and pulling out his facial hair including eyelashes and eyebrows. We stopped the medication in April and he improved. By mid summer, the hair pulling stopped. When his allergies started up again about 10 days ago, I put him back on the Zyrtec, because I was certain the Singulair was causing most of the problems. Within 3-4 days, the emotional outbursts started, panic attacks that never happened before - he said he couldn't breathe. Now the hair pulling is back. Everyone thinks I want to blame medication for his problems, but I am certain that Zyrtec has something to do with these problems in addition to Singulair. We have taken him off Zyrtec 2 days ago. We have a dr. appointment in 2 days and we will discuss all of this with him. In the meantime, his allergies are back and he is miserable. I would rather him be physically sick than mentally at this point.

I have been on Zyrtec for three years (Every day) haven't noticed mood swings in myself? My mother also takes them every other day and is not particularly moody. Although she has trouble sleeping which she attributes to the menopause But if i don't take one within 24hrs I get very itchy and hive up..now that I'm breastfeeding I've just noticed my daughter is very irritable..and am beginning to think it's related to the zyrtec. I'm changing to claratyne in the morning to see if there's a change..very,very interesting and scary reading all the side-effects!!

I am a 37 year old female ~185lbs already under treatment for clinical depression with two medications. I used to take Alavert (loratidine) for seasonal allergies but found it had "stopped working" well for me. Since Zyrtec (certirizine) went over-the-counter, I decided to try it.

I took it sporadically at 10mg daily for a period of 2-3 weeks, and then, during a particularly bad allergic exacerbation, began to take it consistently at 10mg daily. My depression, which was previous well-controlled on medication, worsened to the point of severity. Extreme despair, emotional detachment, and loss of interest in pleasurable activities--well, in ANY activity beyond sleep.

I am a pharmacist, and on a whim, I decided to do some research into interactions with my other medications, and found several anecdotal reports of depression onset and worsening in Zyrtec users. This particular side effect of Zyrtec was unknown to me, nor have I received any educational materials or reports in my trade literature listing depression as a possible adverse effect.

I have discontinued the medication in both myself and my three year old daughter (5mg daily). I can already see a difference in her disposition, and I am starting to crawl out of my pit of gloom. I'm using Alavert again, as I never had one issue with it, and I'm supplementing with Benadryl (diphenhydramine) at night as needed for exacerbations.

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..

My boyfriend has had a difficult time on the zyrtec. He complains of weight gain, depression, and has had terrible trouble with his heart, difficulty breathing. He's not going to take it anymore.

extreme tiredness and depression

I have wondered about the side effects of zyrtec - our daughter has been taking it for 5 year - the same amount of time she has been depressed, negative, etc and these symptoms just get worse as she grows older! I wish she wasn't taking zyrtec. I don't think it's just a coinincidence that her sadness, gloom, and depression began the same she started the zyrtec. She's only 50 lbs and the Dr has her on an adult dose (but she does have severe, severe allergies).

i became severely depressed. lashed out at my friends, spent hours upon hours thinking about commiting suicide, and even more time plotting out ways to cut myself. couln't feel strong emotions, if i was lucky enough to have a moment where i wasn't sad. Positive emotions were very fleeting, and i would start crying or become enraged for the most trivial reasons.

i've been taking zyrtec for 6 years, my depression set in after i turned 13. been off zyrtec for less than a week. i feel a little bit better already.
