| RATING | REASON | SIDE EFFECTS FOR ZYRTEC | COMMENTS | SEX | AGE | DURATION/ DOSAGE | DATE ADDED |
| 1 | allergies | foggy and exhausted | I can't find an allergy medicine that doesn't cause me to want to sleep all day. | F | 36 | 1 days 10 mg 1X day | 4/15/2010 | 1 | Allergies | Mood swings, change in mental state, irrational thinking, dream like states, severe stomach pain, insomnia, crying at the drop of a hat, loss of focus, depression, anger | Don't take this medication. Helps a little with the allergies but rather suffer with the allergies than take this drug again. | F | 19 | 3 weeks 10 mg 1X day | 4/15/2010 | 1 | Allergies | Sleepiness, being in a dream like state, memory lapses | I took one table for severe seasonal allergies and Zyrtec did relieve my congestion however the following morning I overslept, and awoke feeling like I was in a dream. The entire day was a blur and when I came home I was so exhausted I took a nap. This may work for some people but I won't be taking it again. Ever. | M | 50 | 1 days 1 tablet 1X day | 4/15/2010 | 1 | allergies | itching all over my body, developed vaginitis | F | 57 | 3 weeks 30mg 1X day | 4/14/2010 | 1 | Allergies | I have been extremely angry and depressed for the last three days. I also started having flu-like symptoms, so I got on-line looking for Zyrtec side effects because I had just started using the Zyrtec Liquid Gels three days ago. | I am very glad I found the comments about Zyrtec causing mood changes. I had no idea that it might be the cause of my sudden anger. I feel very tired and have flu-like body aches. I will report back if my symptoms disappear after I stop the Zyrtec. | F | 69 | 3 days 10mg 1X day | 4/14/2010 | 5 | seasonal allergies | I started to feel drowsy/tired, but I think it was a combination of the fact that I had taken it at the end of a long day of non-stop sneezing. The allergies had exhausted me and the Zyrtec maybe just completely relaxed me into sleep. | I only take Zyrtec about once or twice a season. It is usually enough to get me through. I'd say I have moderate symptoms but then I'd have one day where I cannot stop sneezing and tearing and at that point I take a Zyrtec (I'm afraid to take it too much). I'll then be free of symptoms for a good 4-5 days. It'll come back, but it won't be severe. On those days I do a saline nose spray and otherwise am able to live with it without suffering too much. Regarding children, I have given my 6 year old the child's Zyrtec formula. But I do a much lower dose - I give him *slightly* more than what is prescribed for 2-5 year olds. The teacher reported that he had a sleepy morning that day but otherwise we saw nothing else, and my son said he felt so much better. In his case too the relief lasted several days. | F | 41 | 1 days 10 mg 1X day | 4/13/2010 | 1 | Allergies | Complete change of mental state. | Glad I found this site. Started taking yesterday and have been in a complete bitter state since. This drug may work for some or it wouldn't be so popular but for others... watch out. If you take and your nose clears up but you wish everyone around you would just drop dead and you curse everytime your phone rings... probably not the drug for you. Glad it only took my 24hrs to figure this out instead of the 6 months, year, 2 years it took others on this site. In addition, I have all the other negative side effects listed, increased appitite, sleepy, etc. So it must be an all or nothing proposistion. You either are fine with it and you have no side effects or you have all. Suggestion, buy the 5 pack - take one - if it works great. However, if you notice any of the negative side effects, toss them out and move on. It won't get any better, it will only get worse. | M | 42 | 2 days 10 1X day | 4/13/2010 | 1 | allergies | I took this as well as my 3.5 year old daughter, I took this med. at night and the next day I was so exhausted. Could have slept all day. No energy to do anything. Felt very grumpy, and hungry all day. Couldn't stop eating. My daughter also was very grumpy, hitting things, and hungry all the time that day. I will not take this medication again. My daughter is normally very happy, never hits anything. | F | 33 | 1 days 5mg 1X day | 4/13/2010 | 3 | Seasonal allergies | I took the one pill once a day right before I went to bed, and it definitely relieved all my symptoms and made me feel great. HOWEVER, I noticed that--even though it had been 12 hours or more since taking the pill--I became VERY tired in the afternoon and evening. Like so tired I fell asleep! This is unlike me. | I believe this pill also gave me strange dreams, like even stranger than the ones I normally have. | F | 35 | 5 days 1X day | 4/12/2010 | 1 | allergies | Daughter 3 1/2-- really scarry to see my outgoing child turn into a non expressive sad child! She hasn't taken this for some time, but each time I give it this reaction occurs. Same with singular. | F | 3 | 1/2 tsp 2X day | 4/12/2010 | 1 | Allergies | Hyperactivity, moodiness, argumentative, irrational, loss of focus, headaches | We put my son on this for his allergies 3 weeks ago. He started having some issues in school, but we thought it was because he hadn't been at karate lately. I took him off the med for a week to see if it was really helping, his behavior returned to normal. However, we put him back on it 3 days ago and he had one of his worse days at school ever. I finally realize it wasn't his karate that was the problem (he's been in lessons consistently), but the Zyrtec. I Googled to see about side effects and sure enough, he's had very similar negative experiences. I also took the 20mg dose a couple of times and had two of the worse migraines I have ever had. I have a very high pain tolerance and I was actually afraid I might have an aneurysm, it was that bad. This drug will never be in my home again. I am rating this for my son as it is more important that people know how awful the side effects can be for children. | M | 6.5 | 18 days 10 mg 1X day | 4/12/2010 | 5 | Severe, Year-Round Allergies | none | Zyrtec is the only allergy drug that has worked for me. Claritin and Allegra do nothing to relieve my itchy throat, eyes, and nose. There are warnings of drowsiness, but I have not experienced this, nor any other side effects related to taking this medicine. My major allergies are every type of grass, oak and pine pollen, seasonal weeds, cats, shedding dogs, dust...you name it, I'm probably allergic to it. March and April are the absolute worst months for my allergies, and Zyrtec helps to minimize my torment, though, during these months, Zyrtec cannot completely eliminate my symptoms. | M | 26 | 5 years 10 mg 1X day | 4/6/2010 | 3 | Asthama/Severe Allergies | WEIGHT GAIN! About 15-lbs or more? Extreme fatigue, sometimes jittery even though I feel like I can sleep too. Turned into a rip roaring "B" to my boyfriend if I drink alcohol with it! Dryed out nostrils in the morning, stuffiness. | I'm glad to hear that it wasn't my imagination about the Zyrtec causing the weight gain. I can't win...I suffer from allergies/asthma or gain weight and don't suffer. Wonderful. | F | 44 | 4 months 5 MG 1X day | 4/6/2010 | 1 | My 6 yr old son had severe behavioral changes within 24 hrs of taking this drug. He was getting bad behavior reports from school that week. He was depressed, cried over little things, had angry tantrums, was violent,incontinence, sleep disruption and falls from the bed. The only change in his routine was the medicine. I remembered the pharmacist saying it differes from claritin in that it works using the central nervous system (we were not getting any results from claritin). I put the pieces together and took him off the drug and already 24 hrs later he is almost back to normal. This is not for every kid - watch their behavior closely if you try the drug. The label does warn of "mental or mood changes." | M | 6 | 10 days 1X day | 4/6/2010 | 1 | My son's pediatrician reccomended | My 5 year old son took it and by the third day his behavior was very strange and he had this perpetual sad or tired expression on his face. He was very moody. Just asking him the wrong question would create an angry response. He became whiney and clingy- very unusual for my son because he is generally very independent and cheerful. Where he is generally understanding and forgiving, he was verbally resentful towards me. By the end of day 4 I could not think of anything that would create such a DRASTIC and absurd change EXCEPT something new. I decided it was the zyrtec and googled side effects. Ta da, There are way too many children under 7 years old with these side effects. | M | 5 | 4 days 5 mg 1X day | 4/5/2010 | 3 | ALLERGIES | Weird Dream, "Hit by a truck" feeling when waking up, Oversleeping | I took a Zyrtec pill and after having the weirdest dream ever, I woke up 5 hours late and feeling like I had been hit by a truck. It did stop my sneezing. | F | 18 | 1 days 10 1X day | 4/4/2010 | 2 | Seasonal allergies | Vomiting, violent shaking, 17 hours sleep | Can't think of anything else that was different in the food that I consumed during the day and I haven't had symptoms this violent before. | M | 52 | 1 days 10 mg 1X day | 4/3/2010 | 1 | Allergies | Dry mouth, had breath | Getting off is tough...heart palpitations, chills, sweats, sensation of yoke around shoulders, chest pains | F | 55 | 12 months 10mg 1X day | 4/2/2010 | 1 | allergies | heart palpitations-rapid and irregular heart beats; severe muscle pain-leg cramps and bursitis;chronic fatigue-felt exhausted all the time; nosebleeds; mental fog-unable to concentrate; difficulty finishing a sentence because I would forget what I was saying;major weight gain-40 lbs in a year. | The palpitations caused me to be diagnosed with atrial fibrillation in the ER a month ago. My leg muscle pain was so bad I couldn't walk 1/4 of a block. Bursitis so bad at night I couldn't sleep. I stopped taking Zyrtec 4 days ago and everything except the palpitations has disappeared. AVOID ZYRTEC !!! | M | 55 | 2 years 10 mg 1X day | 4/2/2010 Patient History | 3 | seasonal allergies | Irregular heartbeat | I hate that this med causes this problem for me, because it worked fabulous on my post nasal issues. I just can't handle the skipping heartbeats. | F | 50 | 40 days 5 mg 1X day | 4/1/2010 |
