 5  Allergies and skin rash None The first day I started taking this once a day (10mg) I felt like a million bucks and had tried Claritin and other pills/liquids. Now I can be around fur for up to 10 hours where as before with the other drugs I would break out within 2 hours. M 29 6 months

 4  Migraines ENT Sx from Mold Exposure AWFUL WITHDRAWAL SYMPTOMS!!! I have had good E.N.T. symptom relief from 10mg zyrtec. Started taking it when I worked in a VERY moldy building in Florida. I've taken it continually for 2-1/2 years; and, luckily, I have not experienced any depressed mood or low energy, etc. ...But whenever I miss a dose for 36+ hours, I get an awful migraine and terrible nausea. I've run this "experiment" -- intentionally and unintentionally -- about 6 times; and EVERY TIME I have the same withdrawal symptoms. When I take a Zyrtec, I feel better about 3-4 hours later. The withdrawal symptoms are so awful that I have not been able to endure the intense headache and nausea long enough to get through the tunnel. I'm going to ask my Dr. what to do about weaning off of it. I'm not on any other meds, so the withdrawal symptoms are NOT some kind of drug interaction -- it's DEFINITELY ZYRTEC WITHDRAWAL SYNDROME. I've heard of others having the same experience, but it seems to BAD WITHDRAWAL SYMPTOMS: whenever I miss a dose for 36+ hours, I get an awful migraine and terrible nausea. It's so bad that I have just stayed on Zyrtec because I cannot endure the headache and nausea. Awful!!! M 37 2.5 years

 3  Allergies Dry Mouth Very Random Dry Skin I had pretty bad Allergies back in late High School and Zyrtec was the only thing that cleared it up, but you have a constant dry feeling for some reason. Not even drinking large amounts of water fixes it either. M 20 2 years

 2  hives drowsiness, dizziness, headaches, moodiness/depression, increased appetite. the first two days on this was fine, but lately have been noticing that i can't seem to get out of bed in the mornings. i feel drugged all the time. can't concentrate on anything and i found myself constantly snacking. i was just rolling around on the floor crying (because for some reason i couldn't understand anything in my fed courts book--now i know that reason is zyrtec), when i decided to google the side effects. glad i found this page and that i haven't lost my mind. will definitely stop taking it. hopefully, i won't itch because the itching does sound scary and i started on this drug to stop itching.

 1  allergies drowsiness, fatigue, numbness, and now intense itchiness and rashes in trying to get off of it. I moved into an old moldy house surrounded by trees and developed allergies for the first time in my life. I took zyrtec daily for 2 years. Now I live away from what I was supposedly allergic to, so I wanted to stop taking zyrtec. Plus, the other day I noticed I had lots of energy and was unusually happy and optimistic. Then I realized that I'd forgotten to take zyrtec that day. So I haven't taken it since (about 3 days) and I have lots of energy, which is good because I have to itch myself everywhere constantly. But I am determined to get myself off of this drug and appreciated everyone else's comments. Any ideas for non-phamaceutical remedies to ease the withdrawal? F 31 2 years

 1  enviro and seasonal allergies Horrendous drug -- zombielike while on it, unsatiable hunger, marked edema, "disconnected" feeling, itching when trying to get off it. This is the first drug I've ever taken that I absolutely *hate*. Prescribed for nasal symptoms in combo with Zantac, I don't think it actually helped that at all - just loaded me with awful side effects such as feeling tired and very, very lethargic, disconnected and totally "out of it" during the day, voracious hunger and unbelievable weight gain even when watching what I eat, and edema like I experienced only when pregnant. Legs with 1/2 inch deep pitting edema, hands swollen, etc. Trying to get off of this is difficult as itching is scary... F 48 3 months

 4  Rash (esp. after taking shower) Dizziness, short term memory loss, depression (severe to mild, depends), loss of hair. Recently after using it for almost 4&1/2 years I sometimes have wiered pain chest. I had couple of panic attacks in the last 6-7 months. I started off with this drug around 4&1/2 years back. Intially I took 10mg per day and it worked really good. Atfer I took it for 3-4 months everyday, I thought that somehow its not good to get used to such drug as sometimes these drugs may cause dependency. So I asked my doctor how long should I take this drug. He said that this is a safe drug and I should take it as long as I have these allergic rashes. So I started taking whenever I had those rashes. I noticed that once I take 10 mg, I dont have rash for atleast 4-5 day , but after that rash comes again. I continued taking the drug for almost 2 years after that. Then I started noticing that I have low concentration, mild depression, I also used to forget thing I should nto otherwise forget. I was pretty much sure in my mind that this drug is the cause for the change in the quality of life I was having. Then I started taking half of 10 mg tablet (ie. 5 mg) every 4-5 days. By then I was taking the drug for almost 3& 1/2 years. M 27 4 years

 4  Rash (esp. after taking shower) Dizziness, short term memory loss, depression (severe to mild, depends), loss of hair. Recently after using it for almost 4&1/2 years I sometimes have wiered pain chest. I had couple of panic attacks in the last 6-7 months. I go under depression even due to the things that I could tolerate very easily otherwise. I know the things but I can not perform well in the exams just because I can not remeber things well even though the subject matter is well understood. I get frustrated very easily. In last 6 months I had visited clinic twice for the panic attack. I have also started breathing problem recently. I cant walk faster. If I climb even 30-40 steps at a normal rate, I get short of breathe. All these problems I have told to atleast 3-4 doctors. Each of them has responded equivocally and dont seem to have the perspective other than prescribing what has been tought and paid to write. I have even asked many these doctors whether or not I should undergo allergy testing to know the reason I have rashes. None of them seem to be willing to write referral for that for god knows whatever reason. As they say it wont help much by doing allergy testing. As per them I need to have a constant watch over what I eat, dri M 27 4 years

 4  Rash (esp. after taking shower) Dizziness, short term memory loss, depression (severe to mild, depends), loss of hair. Recently after using it for almost 4&1/2 years I sometimes have wiered pain chest. I had couple of panic attacks in the last 6-7 months. It will be lot easier for the patient to do self watch, if he makes sure that he/ she is not allergic to the allergens (something that cause the allergy) tested in the allergy tests performed in the hospitals. If you get allergies due to the allergen that is tested in the allergy tests then you know whats the culprit. My request to all people taking this medicine is to keep a close watch at the chenges that you see for yourself, and LET YOUR DOCTOR KNOW ABOUT IT. ASK HIM TO TAKE STEPS TOWARDS KNOWING THE EXACT EFFECTS, SIDE EFFECTS OF THIS DRUG. ITS QUESTION OF HEALTHY LIFE. Thank you. M 27 4 years

 1  Allergies My 6 yr old son was prescribed zyrtec syrup for seasonal allergies with nasal congestion. One hour after the first recommended dose of 1 tsp. he began trembling, complaining of severe stomach pain & dizziness and began throwing up. Quite a sudden change from a healthy (just congested) little boy who had previously been running through the house like he was trying out for the Olympics. Proceed with caution. I think this stuff is a bit too strong for children in my opinion. If you have a small child, I would consider cutting the first dose in half. We were recommended to give this medication another try after waiting a few days...but we will not be doing that. We are done with Zyrtec here. M 6 1 days

 1  For nasal allergiesand sinusitis Started giving myson zyrtec in the mornings which made him groggy- so switched to night.After 2 weeks , I forgot a dose.He woke up at 1.30 a.m. with violent shaking and visual hallucinations.I thought he had a bad nightmare-it did not help that he also had a viral fever at the point. Next two days I gave zyrtec he slept through the fever. Then I missed a dose again and pronto he was up at 1.35 am with the exact same symptoms of seeing lights and monsters.He has never had such episodes before and reading all this definitely points to Zyrtec interefering with the mental state. He is definitely coming off Zyrtec. To top it all it did not relieve his sinus sysmptoms either. M 4 14 days

 5  Itchy skin Somewhat tired but if it stops the prickly skin itchy, I can live with it. I started itching about 6 months ago all of a sudden, thought it was the detergent or soap. My doctor gave me zyrtec and the itching stopped within a hour. I have to take it three times a week to get relief. Without it the itching drives me crazy. Anyone else suffer from itchy skin for no apparent reason? M 39 6 days

 4  allergies no side effects except maybe a little unbalance/dizziness This drug, no matter what it says otherwise in other places, is ADDICTIVE. I have to take it year round as I am highly allergic to many things. If I miss even one pill I get a terrible headche and feel so incredibly nauseous... until I take the pill and it goes away. Every time. It is scary to think it is addictive, but it works so well on my allergies, I can't stop taking it. I've tried EVERYTHING for my severe allergies and asthma and this works the best...just be prepared for what happens when you stop taking it. F 27 5 years

 1  my son has allergies My son who is now 2.4 years old, was prescribed Zyrtec last year. We only had him on it for a little while last season. This season, we had him on it straight for weeks. We've seen a complete change in our usually happy energetic toddler. He was up every hour, if he even went to sleep and he was violent. Night after night - just a few hours after taking he zyrtec, he'd be a terror. Last night, we didn't give it to him and he slept all night. I would never recommend giving this to a small child. IF you do notice mood swings, negative behavior or very long and violent 'night terrors'...take your child off the zyrtec and then go from there. M 2.4 30 days

 1  Allergies I previously wrote on this site about my son and the terrible effects from zyrtec. I am urging all parents and patients to also write the FDA on their experience with zyrtec with the hopes that something will be done so that other parents and children won't have to suffer like we all have. Go to WWW.FDA.GOV then down to LET US HEAR FROM YOU then to REPORT A PROBLEM WITH A PRODUCT. It's very easy to complete and will only take a few minutes of your time. It's important to let the FDA know what's going on. MAYBE we can get something done. Thank you!
