| 1 | allergies | depression and lethargy -- no energy. | i take prozac for depression and allegra for allergies. the insurance company suggested that i try something else because allegra is so expensive. i sleep great but am in a depressive state. coffee doesn't help. so i know what's happened and am waiting this out until Zyrtec leaves my system. | F | 54 | 4 days | 9/11/2008 | 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 | Allergies. Sinus | Dizzyness. Insomnia | F | 54 | 6 months 10 1X day | 10/25/2020 | 1 | Mold, dust mites, pollen, food | Memory loss, balance problems, extreme insomnia, heart pounding, high blood pressure. I have been off for a year and am doing the allergy shots and noticed a difference in only two months. Getting better all the time. Side effects from Zyrtec take a long time to shake. Zyrtec D(with sudafed) is even worse. | F | 54 | 8 days | 2/24/2006 | 1 | ALLERGIES | HAIR LOSS AFTER TAKING THIS DRUG FOR LESS THAN A MONTH. ASIDE FROM OTHER SIDE EFFECTS LIKE LETHARGY, FATIGUE, DIZZINESS THE DRUG COMPANY THAT MANUFACTURES THIS PRODUCT DOES NOT LIST THIS AS A SIDE EFFECT HOWEVER THIS FREIGHTENING EXPERIENCE IS HAPPENING TO ME. I THOUGHT ABOUT OTHER POSSIBLE CAUSES FOR MY HAIR FALLING OUT BUT I HAVE COME UP WITH NOTHING ELSE. THIS IS THE ONLY NEW MEDICATION THAT I HAVE TAKEN IN THE PAST SIX MONTHS. I RECENTLY HAD BLOODWORK DONE AND EVERYTHING INCLUDING MY THYROID IS NORMAL. I'M HAPPY TO HAVE FOUND THIS SITE SO THAT WE CAN FIND OUT JUST HOW SERIOUS THIS DRUG IS. | F | 54 | 25 days | 6/28/2007 | 1 | SEASONAL ALLERGIES | HAIR LOSS! ASIDE FROM DIZZINESS, SLEEPLESSNESS, LETHARGY, MY HAIR STARTED FALLING OUT WITH THE ROOT INTACT WITHIN A WEEK OF TAKING THIS MEDICATION. I HAD BLOODWORK DONE AND MY THYROID IS FINE. THIS IS THE ONLY NEW MEDICATION THAT I HAVE TAKEN. I STOPPED TAKING ZYRTEC AFTER A MONTH AFTER I FOUND THIS SITE AND READ THAT OTHERS HAD THE SAME PROBLEM. MY DOCTOR COULDN'T EXPLAIN IT BECAUSE IT IS NOT LISTED AS ONE OF THE TOP 10 SIDE EFFECTS. I AM STILL WAITING FOR MY HAIR TO STOP FALLING OUT BUT I SEE NO SIGNS OF IT SLOWING DOWN. | F | 54 | 30 days | 7/8/2007 | 1 | Allergies | I went nuts because I was addicted to a drug, that is over the counter. For allergies, I told my boss and co workers that I was having this problem. I won’t bother you with the details of my addiction, I will just say I had a choice between, shingles or losing my mind. The drug is called zyrtec, and it has ruined my life. I was unable to handle any stress when I was on the drug, I was not my happy cheerful self. I was a maniac, a lunatic. I couldn’t control it either, look at the mess I made and I still haven’t gotten any better, now I’m just poor and crazy. I can’t find a job because I can’t explain my behavior, because people don’t want a crazy person around. I’m so sorry that it has come to this, I’m so sorry I’m nuts. I wish I wasn’t and I wish my brain wasn’t messed up from the damage that seems permanent now. I miss my life, I’m so sorry. My life has been ruined, because my mind wasn& | Please warn people | M | 54 | 8 years 10 1X day | 10/17/2012 | 1 | chronic allergies | severe sedative effect. severe and sudden depression, increased vertigo ( spinning sensation and loss of balance). nightmeres almost of a halucinogenic nature. all of these symptoms stopped when i ceased takeing this drug, but it did take approximately 36 hours to feel significantly better. this is a dangerous drug and should be removed from the market by the FDA. the depression and sedative effects could become quite serious if a patient were not aware that that this drug was the cause. i happen to be very atuned to my body and the symptoms were so blatently obviously caused by this drug. however, someone who perhaps already suffers from depression may not be aware that this drug is causing symptoms, therefore, i state again: THE FDA SHOULD REMOVE THIS DRUG FROM THE MARKET COMPLETELY. | THE FDA SHOULD REMOVE THIS PRODUCT FROM THE MARKET COMPLETELY. | F | 54 | 5 days 10mg 1X day | 12/30/2012 | 5 | Allergies | I think zyrtec is a wonderful drug. It keeps me symptomless when I am on it. A doctor told me once that it is too strong and can cause bacterial infections in the sinuses. So I sometimes only take it every other day. I have been very happy with the results, especially since loratidine and allegra do not work at all. | F | 55 | 10 1X day | 2/11/2010 | 5 | animal allergies | none | Zyrtec has changed my life. I have been allergic to all animals all my life. Now we have 3 dogs and I am doing great!!! | F | 55 | 6 months 10mg 1X day | 8/27/2011 | 5 | allergies | Nothing else gets rid of the headaches & runny nose like Zyrtec. It's great. | F | 55 | 5 years | 9/30/2007 | 5 | year-round allergies | None | I've been throught every other prescription allery medication and they all stopped working eventually. I was on Claritin for for some years (when it was still on prescription), and it gradually stopped working. Now it's like popping a sugar pill. Zyrtec works very well for me. I take it at night so that I get a benefit from any potential drowsiness, though it doesn't seem to be a major factor. I've been on it so long that I've lost track, but probably 10 years. If I stop, I can go about 36 hours before the allery symptoms come back. And I agree with the comment about Zyrtec-D. I think it's pseudoephedrine that added to the zyrtec, and that completely spaces me out. I guess you have to figure out what works for the individual. | F | 55 | 10 years | 4/18/2008 | 5 | severe chronic hives | I was asked by a doctor to take 10mg in am and 10mg in pm. As far as I know I had no side effects. I am currently looking into racing heart, however I believe mixing herbs with the zyrtec may have caused the problem with the racing heartbeat. Doctor recommends me to stop all herbs and zyrtec. | At first it did not work for me. It took several months to really kick in, weird I know. I was taking 2 per day at first. After a few years I found I could get by with 1 per day. Now I have been off for 72 hours and so far so good. I still have to give God the credit for healing me. | M | 55 | 6 years | 5/4/2006 | 5 | allergies, eyes especially | none | this is the best medicine I have used for allergies. | M | 55 | 3 weeks | 7/12/2008 | 2 | Allergies | Every time I got in my car to drive, I felt an overwhelming sleepiness come over me. I could not understand why I was experiencing this change in my behavior.When I decided to discontinue taking Zyrtec, my sleepiness while driving stopped. | F | 55 | 40 days 1X day | 1/27/2011 | 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 | 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 | cat allergies | Been taking this for a week. Pain up the back of my neck and ears. Strong headaches in the temple region. I never get headaches. This is pain. Tired muscles, felt like I had the flu. | I did not think the relief I might have felt was worth it. The pain is terrible--like a migraine. Even had a massage therapist work on me. After only one week, I have a very strong feeling this is the culprit | F | 55 | 8 days | 11/8/2008 | 1 | Allergies | Zytec worked well for my allergy symptoms. Worked probably better than any medication I have taken, however, it is not worth the side-effects I experienced | After taking Zyrtec the first time (a few months ago), I experienced tireness to the point of not wanting to get out of bed. I thought perhaps the symptoms might have been coicidental and tried Zyrtec again recently. After 3-4 doses, I again had to drag myself out of bed and felt depressed to the point of tearfulness. Within a couple of days of not taking the Zyrtec, my energy and mood was much better and the symptoms have not returned. I had experienced similar symptoms during the peri-menopausal period of my life, but only after taking Zyrtec have I felt as bad since that period. I take no prescription medications and took only naprosyn and a vitamin when I took the Zyrtec, so a drug interaction does not seem likely. | F | 55 | 4 days | 1/2/2009 | 1 | Sneezing & runny nose | About two hours after taking I have hives on both my hands. This is the second time I took it and this happened before but I thought I was mistaken about it being caused by Zyrtec. If it is doing this, what else is it doing inside? | F | 55 | 1 days | 8/11/2008 |
