 5  Sinus and sinus headaches I have been off zyrtec for 2 weeks... After discovering this website I felt I realized why I had gained so much wieght in 2 years. Also, I was "out of it". I have documented the past two weeks for anyone interested in getting off zyrtec. This medicine really helped my sinuses and sinus headaches. I have been sneezing a lot since I have been off, but I also have more clarity in my thoughts: Looking back, it was like I was living in a dreamlike state. Also, I went off zyrtec in 4 days. I took half of a 10 mg pill the first and second day, and half of a half the last 2 days. I had a terrible headache the first day I decided to stop, which is why I took half of a 10mg pill: guess what? My headache went away when I took it, but it has not returned :) Finally, I want to be specific about my wieght gain. Since high school, in a 15 year time period, I had gained 10 lbs. In 2 years, while taking zyrtec, I have gained 15 lbs. I did not associate the wieght gain with the medication because I started taking it a month after I was married (I thought being married was making me fat because I was cooking more often for my husband and me). THE REVOLATION: I overheard some people at work talking about sinus medications and F 35 2 years

 5  allergies: sneezing, itchy nose Weight gain; sleepiness. I was sneezing about 80 times per day. Sneezing stopped immediately, dropping to 1 to 2 times per day. Was puzzled by the weight gain until I read the comments on this site. This side effect not listed in the nsert, but enough people commented on it here that it seems to explain it. F 44 10 days

 1  allergies Allergy symtoms got better for awhile, then had to switch my son to singulair because he wasn't responding to zyrtec anymore. He took it from age 20 months until 3 years old. He is now diagnosed with PDD. A developmental delay - could it be related? His problems started around the time we started the zyrtec. It makes me so angry that I wasn't informed about the potential side effects. My child is now delayed in speech and social skills. He is been off all allergy meds for 1 week and is much better, talking more and using his imagination.DON'T GIVE THIS TO YOUR KIDS! M 3 16 months

 2  Seasonal Rhinitis Vivid, emotional dreams. Dissociation. Fatigue. Altered thinking. It has been very strange. I'd wake up at night very scared. I'd wake up and think I was losing my mind. Hard to get along with my family while on this - I'm married with 4 kids, so not a great side effect. Great for allergies, no doubt, I'm just not eager to start all the psychiatric medications I'm going to need for the side effects. This is a very weird drug. I thought I was I was becoming mentally ill until I found this site. I think I'll save it for only the worst outbreaks of ragweed allergy and take my licks in the meantime. Nothing else seems to work. M 34 1 weeks

 3  Allergies and cough Only been on this a few days, 10 mg a day, supposed to take it at night. I'm very nauseous. About 45 minutes after I take it, I don't want to think about food. My stomach is very tight and is bothering me. I almost feel like I have a fever but don't. I'm dizzy and seem to be out of it if someone calls at night after I've had the med. Very sleepy and lethargic. Only other thing I'm on is Synthroid and had it for years. It's helped relieve pressure in my head, and if it will help to stop the coughing I've had from pollen allergies this season, I'll be grateful. I'm so groggy and just no energy. F 46 5 days

 2  seasonal allergies depression, weight gain, I never suspected Zyrtec until I read this board. I have been taking this med for about a year and blamed everything else in my life for my symptoms. I gained 40 pounds in about 6 months-I am not kidding. My migraines have become more intense and less responsive to treatment. I take 10 mg at night but I still feel drowsy and I was wondering why I was feeling tired all the time, even though I take Adderrall too. I did have some reduction in my allergy symptoms but there has to be another alternative. I keep gaining weight, I have a black cloud hanging over me and migraines that last for days! And I still get sinus headaches. F 25 1 years

 1  Severe Chronic Hives & Allergies Extreme drowiness, dry mouth, fatigue, weight gain, unable to concentrate I hate this medicine with a passion! So, it gets rid of my hives and allergies, but it is not worth it. I hate walking around all day lot a zombie. And it is not safe to drive at all. F 29 1 days

 3  runny nose and other allergies With my first son, I noticed that he only got in trouble at pre-school on the days I remembered to give him his zyrtec. We had to choose between good behavior and runny nose. Now my two year old has been taking zyrtec for a year and a half. I am considering taking him off the medication because his behavior is awful. I had no idea so many other parents have had the same problems. Zyrtec worked wonderfully for both my son's when the had a runny nose and helped stop the cycle of runny nose then bronchial infection.

 5   late onset lethargy & extreme weight gain I've noticed if I take the pill in the morning, that by 8:00PM I'm ready to almost black out, I'm extremely tired! Couldn't figure out what has been causing my rapid weight gain & hunger. I'm ALWAYS hungry, and never satisfied. (I'm not pregnant either!)I've noticed more drastic weight gain in the last few months & I've been taking zyrtec more consistently because of the season. Those are my only complaints, but it does REALLY help with my allergy symptoms. Guess it's a give & take. No more allergies but now I'm fat. F 29 1 years

 1  severe allergies and sinusitis Severe edema, elevated eye pressure, hives and itching upon trying to stop zyrtec. Anxious to see how long after stopping the zyrtec edema and eye pressure are affected. Though zyrtec worked to control my allergies, the addictive nature of the drug scared me. I have tried numerous times to get off it and the terrible itching and near panic attacks drove me crazy. I have now been off it for a week and am trying to put up with the itching with OTC Claritin. I have found that ice helps calm the nerve endings. NO DRUG IS WORTH THIS KIND OF WITHDRAWAL! How long before it's completely out of one's system? F 57 8 years

 2  Seasonal Allergies My 6-year-old daughter went from a happy, beautiful child to an emotional trainwreck. Allergies and puffy eyes went away, but in their place was a teary, depressed, befuddled and evil child who slammed doors, broke glass, and acted out verbally. I am mortified that I put this poison in my daughter's body. After reading the other comments on this site, my heart goes out to all parents who tried to help their kids and, like me, turned them into monsters. My daughter has 10 days left in the school year, and she will attend with puffy eyes and a booger nose, and be her happy, normal self again. I'll spend the summer finding alternatives that let me keep my daughter sympton free AND happy. Any other parents, feel free to e:mail me! F 6 30 days

 1  Chronic Sinus Infections Irritability, crying, sour throat, tiredness When we tryed taking her off, our normally well focused child has problems following directions, focusing, itching and stomach pain. None of these problems existed prior to medication. She was originally seen for sleep apnea type symptoms and chronic sinus infections. If we use this drug in combination with Singular, the sleep apnea type syptoms seem to go away, but I wonder if their masking it because their making her sooo tired. I did sleep with her one night and she still had irregular breathing during sleep after taking just zyrtec. When we initially went to our Dr. about our daughter (she was 3 1/2) waking at night saying she couldn't breath and having constant sinus infections, we were sent to a ENT that said there was nothing wrong with her. We insisted something was wrong, her beathing was irregular at night. Our Ped. referred us to an allergist who put her on Zyrtec and when that wasn't enough, he put her on Singular as well. I hated the way she seemed like she was a zombie, so we just put her on nasal spray. We finally took her off everything and she experienced extreme itching in her ears and stomach pain. I agree that this drug is addicting, I put her back on and her itching and stomach pain stopped. After reading all these notes, I am t F 7 2 years

 5  Allergies and sinusitis My daughter is taking it since a month ago and we have not noticed any wrong side effects, we are giving her the mexican equivalent (called Virlix). I am assuming that the problem of the side effects others are expiriencing could be residing in the formula of Zyrtec. She has been previously on Clarytin, Benadryl, etc. and none has helped her as this one... Maybe if you could get the Mexican variation of the same drug you could give a try, there is no need a prescription to buy it there... best wishes to you all. F 3 1 months

 1  allergies Fatigue, tiredness, overeating, stomach aches. Took zyrtec for 7 days - only took 5 mg (1/2 a pill) at night before bed. Was tired, sleepy, fatigued the entire time. Also over-ate. When stopped taking Zyrtec, felt nauseated and had sinus headache. Tried Claritin as well, but it made me feel very jumpy and had hard time sleeping. F 29 7 days

 3  seasonal allergies very real, anxiety-causing dreams just prior to waking up in the morning--not fun! While it was an effective antihistamine, I had to stop taking it after several weeks due to the anxious-dreams side effect. Also, as with all antihistamines and nasal steroids I've tried, Zyrtec caused me to eat more. I couldn't put food down, even when I figured I was full. F 44 8 weeks

 3  allergies, asthma Severe tiredness...falling asleep at work at my desk, unable to concentrate, making tons of mistakes and errors at work, forgetful, generally confused, weight gain, stuffy nose, dried blood coming out of my nose. I was so tired and didn't put 2 & 2 together until I read comments on this website. I slept from 4:30 pm until 9:00 am the next morning without waking up... called in sick to work... too tired to make it in... too tired to exercise. M 48 1 months
