Zyrtec and allegra

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.

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.

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!!

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 have taken Zyrtec for years during the fall during ragweed season - works great for me without any side effects. My husband can only take it every other day as it makes him feel flu -ish. 18 yr old takes as needed and it works great. 16- yr old has allergy asthma and has taken Zyrtec for years and now with Singulair. She now is experiencing all noted problems of sleeplessness, headache, anxiety, and grumpy. We are quitting the Singulair to monitor improvement and will do the same with Zyrtec if needed.

NOTE: Each person most be monitored with every drug for allergies and side effects. If you or your child cannot tolerate a drug, STOP taking it. You are your best daily diagnostician! Your DR. may not agree or understand, but pursue another course. REMEMBER though, that drug may be a lifesaver for millions of others that react favorably! Penicillin is a miracle drug unless you are allergic! Doctors should encourage close monitoring whenever your kids take a new drug - but when they don't - that's our job!

I took Zyrtec for a few years for severe mold and pollen allergies. I loved the drug as it controlled my allergies much better than Allegra or Claritin. However, I recently stopped taking it after realizing it was causing dizzy spells, drowsiness/constant tiredness and heart flutters. Since I stopped taking it I have lost 6 pounds without making any alterations to my diet and exercising less than normal. This leads me to believe that my weight gain of 30 pounds in the last few years was also part of zyrtec's side effects.

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).
