 5  allergies Our son was on this drug for a little over two years. His dosage continued to increase over the time period due to increase weight - he would eat all the time. That was the least of our problems. Our son was aggressive, moody, tired, I could go on forever!!! Jake was in preschool and having a difficult time focusing, getting along with others, and the teacher started to get concerned as well. I am a teacher and was going to ask the peds. for a full scale evalution, due to his behavior. To make a long story short, we had to find a new allergy dr, and he had us stop giving Jake the meds for his upcoming allergy tests. Within a few days we got our son back. He doesn't have the outbursts and other behaviors, Jake is that happy child he once was. We are grateful to have our son back, however, we feel cheated out of 2 years of his childhood. We were so grateful we found this site last year. Would not recommend this medicine to anyone 2 years

 4  allergies Zyrtec can put you into the biggest raging frenzy. you wont be friendly or patient and you wont know its happening either! this is a powerful mind altering drug, you can completely dissociate and not realize how you are acting until you come out of it! there are some GOOD things about zyrtec, it works very well for allgergies and itching, sneezing, swollen eyelids, runny nose but it can also knock you out like nothing else! you will have a incredible unconcious desire to sleep, for 10-14 hours. sometimes after taking zyrtec i lose 2 days! your body will just want to switch off. its my theory that zyrtic is an incredibly potent stimulant that acts on the nervous system that supresses a lot of self control.

 3  Allergies Check out Pfizer's fact sheet on Zyrtec: www.pfizer.com/files/products/uspi_zyrtec.pdf "The most common adverse reaction...was somnolence...6% in placebo, 11% at 5 mg, and 14% at 10 mg." Fatigue was a 5.9% incidence vs. 2.6% on placebo. Many of the other symptoms represented on this page were concomitant with Zyrtec use, albeit at less than 2% frequency.

 3  Heat bumps on skin, heat/sun I had huge heat bumps from heat/sun allergy. Zyrtec took down the bumps big time, but left an itching that is horrible, I can't scratch it's now so tender. Very drowsy during the day time, even though I had taken them early evening. If any one has any suggetions for curing heat rash on the skin I would appreciate it very much. M 3 days

 3  Allergies: Seasonal/pet/ medicine Weird dreams, Irrational thoughts, heart racing, weight gain, hair loss/thinning, mood swings, sinus trouble, lack of focus and memory loss. This medication was excellent in helping me sleep through the night. Without meds I suffer from clogged sinuses, and headaches with itching daily. It allows me to be able to get through the day okay, but the side effects are not worth it. I am very suspect that this drug is behind my hair loss, and will discontinue the usage and try another medication to control my allergies that will not have so many side effects. This is an excellent site, I got to compare my side effects with others and learned new things about the medication. F 8 years

 3  headaches from allergies I came to this site to see if others are having the problem that I am -- and i see that they are: very sleepy in the morning, irritable, and hungry all the time. i've gained about 5 pounds already. also, when i stopped (for the above reasons) SERIOUS allergy symptoms like i've never had before -- 3 days of sneezing, migrane headache for the first time. i'm hoping to find another drug. 6 months

 2  Grass, food and dust Allergies My 8 month old son has been taking Zyrtec for about 3 weeks now as he was diaganosed with several food allergies as well as grass and dust. This was about the time he quit sleeping through the night. He has been waking up screaming, as if having a bad dream. This happens about 5 times a night. His cough, runny nose and sneezing have not gone away. After reading comments on this site, we are taking him off of it immediately. I'm convinced he will go back to sleeping better off of the drug. M 3 weeks
