 4  Allergies Tiredness, sometimes dries me up too much. This works very well, but sometimes over dries my nose, so I stop it for a day or two. Makes me rather sleepy, so I take it at bedtime and sleep like a baby. M 53 1 months

 4  Allergies to pollen, dust and molds 5mg Zyrtec works just fine for my symptom control. I have been on 5mg for the last 6 years.(I now split the 10mg. OTC in half) 10mg causes blurry vision about 2-6 hrs. after taking it. I recommend it IF you monitor your symptoms vs. side effects. I tried Claritin but became EXTREMELY AGITATED AND IRRITABLE after only 1 dose. I tried Claritin again to make sure of the side effects. Same results. Buy the generic when it is on sale at Rite-Aid. You will save a TON of money. M 53 6 years

 4  allergies and hives None that I was aware of at the time. I stopped taking zyrtec about 1 week ago and have had horrible itching. I thought at first it was from a new detergent but switched back to the old with no relief. Now reading this site I think I am in withdrawl. However I have never taken anything that worked so well for my allergies. I did develop a ringing in my ears shortly after starting it and wonder it anyone else has had that as a side effect? It is not going away since I stopped but it hasn't been that long yet. F 53 2 years

 4  Allergies Deep depression and muscle and joint pain. Could not walk without pain. Sleep disorder as well. Could not fall asleep and then waking up all through the night. It helps with the allergies but the side effects are not worth it. F 53 40 days

 3  Allergies Severe body aches, dry mouth, heart palpitations I've been on Zyrtec about 2 years now. My severe body aches (to the point that at times it's very painful to move much) started a few months after I began the drug, but I never connected the two until now. My allergies are now nonexistent, though. I've missed a pill now and then and have never had any withdrawal problems. F 53 2 years

 2  hayfever Took 1 tablet before bed. I woke up extremely tired and spent the entire next day so extremely tired, I thought I was narcoleptic. I have used Zyrtec before with the only negative symptom of feeling like I was one step behind. This time there was no way to "wake up." I took 2 hour naps and was really not able to function until 24 hours after taking the Zyrtec. The next day I took Claritin and had no allergy symptoms and no drowsiness. I will not use Zyrtec again.

 2  Year Round Allergies I take zyrtec at night before going to bed. I find that I have problems waking up in the morning. It's as if I am in a drugged stupor. I had been taking allegra-d but was told that I needed to switch up my allergy medicine so that my system did not get used to the medicine. I have been on allergy medicines since I was 20.

 2  dust, mold, pollen allergies loss of smell mixed with everything smelling like peanutbutter - - uncontrollable appetite and weight gain - - depression F 53 2 months

 2  ALLERGIES Drowsiness, lack of concentration, irritability, severe dizziness to the point of almost passing out and weight gain. My face was swelling due to seasonal allergies and the doctor put me on Zyrtec and instructed that I take it at night. I do but am still somewhat drowsy and disoriented during the day. It did help with the seasonal allergies, which was a first for me. I thought initially that I had a sinus infection but not so. I might take these occasionally but don't want to stay on them continuously. F 53 2 weeks

 2  seasonal allergies When I first started taking Zyrtec 8 months ago it made me very tired. Now I can not sleep until I am exhausted. It definitely stopped the sneezing, runny nose, weepy and itching eyes. My doctor says to keep taking it because I can't hear out of one ear. After 8 months I am beginning to think the Zyrtec may be causing the hearing loss? I have been off it for two days and my blood pressure is up above 140 and I feel flushed. Would love to be able to sleep like a normal person again. F 53 8 months

 1  itching sleepiness, irritability NEVER AGAIN! I also have sleep apnea. This medication makes me so sleepy that I can not wake up when I stop breathing! I took it at 10pm and still feel the affects at 6pm the next day. When driving I had to pull over to sleep because I could not stay awake. I have also been yelling at my husband for two days for no reason at all. This medication is not worth my marriage! F 53 2 days

 1  severe allergies/coughing This was the first med that contolled my allergy related cough. I was thrilled. It took the drug for about three months. However, I began to feel that I was becoming very sad. It started so slow that I didn't realize it at first. I had achy bones, and was tired all the time. I thought I had a aerious illness. But worse than that was that over the three months I became more and more weepy and sad. Then I heard that Zyrtec can make you sleepy, so I stopped taking it. By the next day, I suddently realized I was happy again, I was my old self. Now looking back, I see how I was sinking into a deeper and deeper sadness, but didn't realize it. When on this drug, as the days went on, I went from being sad, having no energy, to crying over every little thing. For me, it was a slow progression into deep sadness. Looking back, i now see how bad off I was. So I will put up with coughing. I'm so glad I stopped it when I did. There is not telling how far down I would have gone. Please beware of this F 53 3 days

 1  chronic (over 2 years) hives severe leg aches, breast tenderness I was prescribed Zyrtec to help control chronic daily hives. It didn't seem to have any effect at all on the hives and for the entire time I was taking the drug I felt like I had the flu with body aches that were particularly bad in both calves. All bad effects were gone the day after I quit taking it. F 53 21 days

 1  Allergies Took with Avelox - major hypnotic effect. After Avelox kept taking - kept being very very dizzy - esp. when lying down. Stopped Zyrtec 6 days ago. Good news not dizzy at all anymore! But ITCHY. At first got very itchy palms and skin with red rash. Also eyes very itchy. Taking Benadryl at night now (can't take during day as it makes me too sleepy). Itch better but still there. Hope it goes away. I would not rec this drug to anyone. Side effects too serious. Esp. do not combine with Avelox! F 53 60 days

 1  Allergies Fatigue, extreme irritability, sore throat, back and shoulder pain,erratic sleep. Terrible, terrible drug. Do not take it! It made me so irritable that I wanted to snap at everyone for the least little thing. Just felt terrible the whole time I was taking it. The side effects were much worse that the allergies I was taking the Zyrtec to treat. I'd much rather suffer from the allergies than from these side effects. It was that bad. M 53 3 days

 1  seasonal allergies My son committed suicide because of this drug. He was 18 years old with seasonal allergies. He had tried Clariton before but didn't work too well. Heard about Zyrtec and decided to try it. Was on it for two months then committed suicide. We found out he had been depressed,became withdrawn, hearing voices, not sleeping well. Never took anything else, never had any problems mentally before. Was a straight A student, happy, had everything going for him. The only thing different in his life was taking the Zyrtec. I attribute Zyrtec to his suicide! Especially after reading all the negative comments from everyone else. F 53 2 months

 1  allergies I only took 5 doses, I could smell before I took them even though I was sneezing,coughing, and having a runny nose. The drug cleared up my nose and took away my Total sense of smell. Today is 4-2-09, I took the pills in the 1st. week of March 09, so I have been without my smell for about a month. I only took 5 doses,2 and 1/2 days. I can not smell anything at all and even though I can still taste,it seems not as much as before. Now I find that it's really dangerous because I can't even smell smoke. I rushed to the store and got 2 smoke alarms for safety.I will now have to be more mindful of my food spoiling, cause it could look okay, but now I can't smell to be sure. I think of all the things I'm going to miss,like puppy breath( only true dog lovers knows that wonderful smell). A new doctor has given me 7 days of an antibiotic, Nasacort nose spray and 2 shots, its now day 3 and I do not think it's going to work. If I have to live with this I sure won't like it, but on the upside, when I'm picking up the dog mess in my yard from my large dog I don't smell it. And I want smell the dead skunk in the road. Has this happened with anyone else like me in just days time? F 53 3 days
