| RATING | REASON | SIDE EFFECTS FOR ZYRTEC | COMMENTS | SEX | AGE | DURATION/ DOSAGE | DATE ADDED |
| 3 | allergies | migraine, lasting until the dose wore off. | M | 1 days | 5/4/2009 | 1 | seasonal allergies | Pimples on chest, shoulders, and upper back. Periods of constipation followed by painful, large, and loose BMs. Decrease in energy and water retention/minor weight gain. | I have taken Zyrtec off and on over the last few years for my season hay fever, and when I noticed the strange changes happening to my body, I wondered what it could be from. I stopped taking it 3 days ago and my acne and BMs are back to normal and I have lost 3 pounds in what I assume was water weight. Needless to say, I will not be taking Zyrtec again. | F | 23 | | 5/3/2009 | 1 | Allergies | Extreme agitation, screaming, moody, hyper... | I chalked his hyper and out of control behavior on just being 3, but when my normally content and well behaved son turned "demonic" I started searching online to see if the zyrtec I have been giving him for almost a week had anything to do with it...seemed kinda strange that almost immediately the same day he started acting out and just being almost impossible to deal with!! I came across this site and read of other little ones that have the SAME side effects! I haven't given him a dose today and plan on throwing this crap out! Back to benedryl at night! | M | 3 | 4 days | 5/3/2009 | 4 | spring allergies | weight gain | Very effective at controlling my allergies. I'm perhaps a little drowsy, but I counter that by taking it at night and drinking coffee in the day. In another month, allergy season will end, and hopefully I'll be able to lose the weight. | M | 33 | 30 days | 4/30/2009 | 3 | spring outdoor allergies | irritability, anger issues, cranky, argumentative, rudeness, negative | We've had horrible behavior issues that last long for the past few days for no reason at all. Finally tonight it dawned on my husband and I that we just started giving him the zyrtec this week. I'm taking him off tomorrow and hopefully he will be back to his old 7 year old jolly self. It was helping his spring allergies,but we'll have to find something else because I can't deal with those side effects. Also it contains parabens in the ingredients and those are not healthy for humans according to my most recent research. Alot of beauty items in fact are advertising paraben free on the packaging. | M | 7 | 5 days | 4/29/2009 | 2 | seasonal allergies | Depression, anxiety, Always irritated and lost pounds of hair becoming almost bald, appetite loss and very very sleepy!!!! Worked only if i took 2 tables a day. | Man i had no clue my depression and anxiety were because of zyrtec, i took zyrtec last year for the allergies OTC i tried it for 3 months and i took it regularly for almost 3 months, though my nasal symptoms have subsided i started having eczema and irritated eyes. During that period i had the hardest time in my life i was always depressed not at all interested to speak with anybody and had anxiety related issues.... i seriously thought it was my job search making me that way but now after going through this site i have realized it is the medicine and i even went to the doctor who could not even make out why i had anxiety issues as i never had these problems in my entire life ..... the worst part was once you i stopped taking this medicine i starting scratching a lot and lost so so much hair i thought i was going bald, thought i have recovered all that hair now and as the season has just started i was considering some allergy medicines and came across this site. Thank you guys so much i would not have none ZYRTEC WAS CAUSING DEPRESSION!!! I will meet an allergist and find out if i can get some other medicine. | M | 24 | 4 months | 4/28/2009 | 1 | allergies | I felt drowsy and hyper at the same time. Dry mouth,very weak, foggy minded, sweats, nauseous, light headed and dizzy | Was counting down the hours until the medication wore off. Do not recommend for anyone, especially young children. I have very bad allergies during springtime, but would rather deal with the allergy symptoms than zyrtec side effects. | F | 24 | 1 days | 4/28/2009 | 1 | seasonal allergies | I was a zombie 24/7. Couldn't function and it was affecting my mood. My two-year old who is normally very sweet-natured turned into an aggressive manic. | Horrible side effects. It barely took the edge off of my symptoms, but it did clear up my son, although at a price that I'm not willing to pay. | F | 33 | 5 days | 4/28/2009 | 3 | indoor and outdoor allergies | fog-brain, lethargy, sleepiness, irritable due to tiredness | 3 people in my house on zyrtec- 4.5 yr old (since 1 yr old for confirmed dust mite, tree, weed and grass pollen allergy); 2.5 year old (since 1.5 yrs for confirmed tree, weed and grass pollen allergy); me- 30 - started 2 weeks ago for confirmed dust mite, tree, weed, grass pollen allergy). For the people whose children are irritible, "possessed," cranky, etc- they are probably tired and it is probably from the medicine. Make sure you give it to the kids at night! I made the mistake of taking it myself first thing in the morning and could not be my motor going, so to speak- just wanted to nap all day. For me and my older child, it definitely has a sedating effect. For my younger child, Zyrtec works for his allergy symptom relief and seems to have no side effects. Everyone has a different body chemistry. I am allergic to cats as well and so is my youngest, but my oldest is not. I am allergic to dust mites and so is my oldest, but my youngest is not. We do see an allergist and had the testing done and the pediatrician also tells us when to increase the dose for the kids based on age and weight. Make sure you don't give the kids too much - that's a danger of OTC and not asking the doc before you give kids an antihistamine drug. My oldest started on 1/4 tsp and gradually increased based on his age and mostly his weight. If you start a 2 year old on the max. dose per the OTC bottle, it might be too much. PS- My oldest also has reactive airway and we tried Singulair for | F | 30 | 3 years | 4/25/2009 | 2 | Allergies | I have been around the same weight my whole life, but I started taking Zyrtec 4 months ago when the doctor told me that an infection that I had may have been due to allergies. I continued taking it into the spring, b/c I always have seasonal allergies. In these four/five months, I have been gaining weight slowly, but surely. I eat very well and exercise daily, so I was very upset and confused that my clothes don't fit anymore. I gained about 10-15 pounds. I am going off this med today! Id rather suffer with spring allergies than not fit into my clothes! | The medication does work, (I have had NO allergic symptoms, and that is amazing, since I am very allergic to any plant, tree pollen) But I am NOT dealing with these side effects. Going off of it TODAY and staying off FOREVER! | M | 25 | 5 months | 4/25/2009 | 1 | Coughing from post-nasal drip | I gave my 5 1/2 yr old son this medication and within a day he was moody and miserable. I didn't immediately connect it with the medicine, I just thought he wasn't feeling well. I gave it to him for about 4 days and also started my 8 yr old on it when he started with a similiar cold. They were at each others throats, fighting and generally irritable. I stopped the medicine for both of them and it took about 2 days for them to be back to normal. What a drastic reaction they both had. I will never give it to them again. | M | 5 | 4 days | 4/24/2009 | 2 | allergies | My 4 year old son was placed on this medication for his allergies. Almost immediately he became a different child. "Possessed" comes to mind. He was extremely aggitated and irrational. | He will not get another dose. I'm glad I came across this website. | M | 4 | 1 days | 4/23/2009 | 1 | allergies | abdominal pain, vomiting, clingy, excessive crying, sleeplessness | I gave this to my 1 1/2 year old for allergies, after it was prescribed to her by her allergist. What a horrible drug! She ended up at the ER for abdominal pain and vomiting. If I had seen this website before giving her the medicine, I would definitely not have given it to her. | F | 1.5 | 3 days | 4/23/2009 | 2 | Chronic Hay Fever | Wired, anxious sleep, drowsiness, apathetic mood. | ZYRTEC was effective in stopping my allergy symptoms, but after 3 days on this medication, with very little sleep, and the sudden apathy, I stopped, and returned to "normal" within 2 days. There should be more extensive warnings for this allergy medication, and it should be taken off the shelf. I will go back to taking Claritin "D" full of pseudofed which makes me wired also, but with no mental side effects--and I can't take that for more than 1 or 2 days! | M | 61 | 3 days | 4/22/2009 | 1 | cholestasis of pregnancy | extreme grumpiness and anger, tiredness, confusion | I took one tablet for the first time last night and will NEVER take another. I have not felt this disgusting for years. I am feeling extremely angry and disgusting, as if I have a massive hangover and very jumpy. It should not be on the market | F | 35 | 1 days | 4/21/2009 | 1 | Seasonal Allergies | Became agitated, depressed, irritable...violent thoughts. Normally I am very laid back and happy. Did not know this med could cause such mood problems. Worked well for allergies but not worth the problems it caused. This stuff is dangerous... | M | 38 | 7 days | 4/21/2009 | 1 | seasonal migraine headache control | 5 pound weight gain after just 5 days of medication! cognitive impairment, vivid dreams | F | 54 | 5 days | 4/20/2009 | 1 | seasonal nasal allergies | Right sided cardiac failure and hypertension. I experience "cardiac asthma" ie.wheezing after exertion with difficult breathing | This should not be over the counter. Who knew, from the sweet little TV ads that this drug could have killed me. | F | 58 | 2 weeks | 4/19/2009 | 2 | Allergies | As others have listed, the first two days of using Zyrtec were "Very foggy"- My mind was in a complete haze. After day four came the aggressive behavior and mood swings. After a week came the depression. Zyrtec did work very well in stopping the allergy symptoms, however, the side effects frighten me. I chose to suffer the allergies. | M | 38 | 2.5 weeks | 4/17/2009 | 3 | SEASONAL ALLERGIES | ANXIETY, AGGRESSION, AGGRAVATION | Started taking Zyrtec after my claritin failed after 10 years. This Zyrtec absolutely gives me allergy relief but I am not quite certain the people around me are happy about that. I feel a change in my demeanor and attitude about an hour after taking the pill. I am less than tolerant of everyone at this point and absolutely see a change in my mood. I am still trying to decide which is the lesser of two evils...my happiness from allergy relieve or my co-workers' happiness from having me stop the medication! | F | 42 | 5 days | 4/14/2009 |
