Levocetirizine "What worked for me: - Take at least 10, 11, or 12 hours before you need to wake up - Take half of the tiny tablet if you are small - Drink tons of water during the day My lungs couldn't take the pollinated air this season. It's been months of scratchy lungs, impossible to take deep breaths, have lost my voice twice, often couldn't talk without being overwhelmed with coughing fits, scratchy throat, and watery eyes. I took a whole (tiny) tablet one night - it was too much; didn't like how I felt the next day. About a week later, I read this site and saw that someone took a half dose, so I tried it. (I am a smaller person.) Been taking half doses for 5 nights now and seems to help significantly with my breathing for the most part, though my body feels a little swollen (female) and my eyes are still mildly watery at times. It's a huge relief to be breathing freely and to have the increased energy due to the increased amount of oxygen I am finally receiving."

Levocetirizine "I had been taking Allegra and Nasonex for years, but still did not have good control over my allergies and asthma. I used Benadryl as needed when my two prescription medicines were not enough. The pulmonologist told me that Benadryl has an intense drying effect in your body and that it makes your mucus more viscous (thicker). Within 2 days of starting Xyzal (and stopping Benadryl), I definitely had thinned mucus and my skin was much less dry. My asthma was much better controlled and I had less sensitivity to environmental triggers. Unfortunately, I also started experiencing moderate-to-severe headaches along with a feeling of depression/anxiety. Without Xyzal, I get pneumonia, with it, I feel crazy. Works, but bad side effects."

Levocetirizine "Love this medicine!!! I have year-round allergies and I am allergic to everything: dust, cats, hamsters, everything outside, etc. I feel like I should live in a bubble. Nothing seemed to work. I've taken OTC drugs and prescribed drugs. All of them stunk. Allergy shots really work, but are too time-consuming. Then I found Xyzal. Love it! Fair warning though, this drug does knock you out and the lasting effects carry into the next day, but I discovered that if you take it about an hour to two hours before your bedtime, you will feel fine the next day."

Levocetirizine "Absolutely horrible, unless you like feeling dopey, drugged, and hungover for three days after a single dose! It did help my allergies, but the side effects are much too pronounced and severe to warrant ever taking it again. I'd rather suffer!"

Levocetirizine "Not only do I have allergies, but I also have asthma and chronic sinusitis, along with occasional nasal polyps. In addition, I have had a chronic cough for three years, which doctors could not, or would not, help me with. They had no answers. I took XYZAL, and lo and behold, the chronic cough has been drastically reduced! I hope it lasts; I've become reluctant to go shopping or even to church because of the persistent cough. I know it's not for a cough, but it has certainly helped mine! This remedy is now OTC, so I won't have to plead my case to the doctor."

Levocetirizine "My allergies are the worst in the morning, and this medication directs it to be taken at night. I've tried that several times, and it is no help whatsoever. Just before writing this, I had to take Benadryl even though I took this medication last night. Very disappointed in this product! The couple of times my allergies kicked up at night and I took it, this product did not help at all. That said, everyone is different, and I guess if you want to try it and see if it works for you, go ahead. But if your allergies are bad in the morning, it will not help at all."

Levocetirizine "Xyzal has helped keep the chronic sinus infections away while on a biologic for an autoimmune disorder! That's a miracle! I love Xyzal. Some days I get sleepy, so I take it at night. Now, if I can just get the autoimmune symptoms to go away, I'd be kicking booty! Love Xyzal for allergies!"

Levocetirizine "My boyfriend bought this for his seasonal allergies, and it worked great, and he slept great. I suffer from several chronic pain conditions and decided to try this for sleep (which is hard to come by when you're in pain... painsomnia). I slept the best I had in months. I woke up feeling refreshed, with no drowsiness. I've used other allergy meds in the past to help with sleep, but they don't always work, and when they do, I wake up drowsy. I'd love to buy a case of this, because each time I've taken it, I slept great. I'm glad he found this product."

Levocetirizine "I wouldn't wish this on my worst enemy. Kept me up, maniacally freaking out, until 4 a.m. Followed by extreme nightmares and tossing and turning. My head felt like it was going to explode. I literally almost went to the hospital. Terrifying."

Levocetirizine "My seasonal allergies just started this week due to high pollen count. I was very hopeful for the 24 hr relief promised by Xyzal, especially because it is taken in the evening. I thought the main 'drowsy' effect would be limited to the nighttime. I was wrong! I woke up feeling terrible, could barely wake up, and had to drag through a fog all day at work. Not for me, unfortunately! I guess back to non-drowsy Claritin."

Levocetirizine "I have a cat and a dog in the house, so my nose runs all year long. I had taken Benadryl daily until the doctor told me to take it twice a day because my body had gotten too used to it. I then tried Claritin and Allegra, neither worked for me at all. I then switched to Zyrtec, and that was pretty great. I still had a runny nose, but not as bad. When Xyzal came out, I had to try it since I had a crack in my nose for about 6 months from a runny nose. Within 1 week of taking Xyzal, the crack had healed, and my nose wasn't runny. This is a miracle drug for me. I believe that each body is different, and you need to take the drug that works for you. I take this during the day, as it wore off when I came home from work to be with my animals."

Levocetirizine "I wanted to share my experience with taking this medication. I started taking this medicine and felt a little better with the allergies, however, I noticed my mood had changed. I started feeling very depressed about a week into the medicine, and that is NOT like me at all. I am usually someone who wakes up with a burst of energy and always in a good mood. My allergy symptoms were improving a little bit, but now I am in a state of depression. I was having mood swings and mentally breaking down, crying for reasons that I usually wouldn't cry about. I talked with my doctor, and we agreed that the medicine was making me feel this way. Today is day 4 without taking the medicine, and I am back to my normal bubbly self. No more Xyzal for me."

Levocetirizine "Tried Xyzal for the first time last week. I noticed I was a little groggy, which I've come to expect from most antihistamines. After taking it for 4 days, I have become an absolute mess. Very irritable, moody, crying, and angry. Just generally feel like I'm losing my mind. My 5-year-old daughter had the same reaction. And it didn't even help with the sneezing, runny nose, or watery eyes. In fact, it's given me a headache on top of making me feel insane along with all the allergy symptoms. Back to Claritin for us."

Levocetirizine "I have had sinus issues for the last 40 years. Tried this drug - took 1/2 a pill at bedtime as suggested. Did not make me sleepy at all. In the morning, I got up and was in a puddle of sweat. Thought the hot flashes were just worse. Also, my stomach hurt somewhat. After some time, stopped taking them - the sweating stopped. My stomach is now fine. Too bad - it really took care of my allergies."

Levocetirizine "Shortly after taking Xyzal because I wanted to try a different allergy pill than Zyrtec. My throat, nose, and eyes began to itch and burn really badly, and I think it's because of the lactose monohydrate ingredient, but it's not for me at all!"

Levocetirizine "The reviews are true!!! I normally take 12-hour Allegra-D (as needed). When I took this, I immediately felt worse, my nose wouldn't stop running, I got very hot (red), and I was coughing almost like it made it worse. I felt it kick in and got extremely heavy. My nose felt like I was at the bottom of a pool, swollen, my eyes were puffy, my vision was impaired, I had horrible nightmares, and I barely woke up when my alarm went off. I felt worse than when I went to bed!!! Fatigued all day, bloated, headaches, swollen nose, and massive sinus pressure when I looked down at work. It felt like my senses were numb and I wasn't human. Everything everyone listed negative is true. I will NEVER take it again, and I'm shocked it's still available OTC. Do NOT waste your money, it's total fraud."

Levocetirizine "I was desperate for something to alleviate coughing, which was severe to the point that I had trouble breathing and terrible accompanying chest pain. I purchased Xyzal OTC and used just one dose last night, no other meds were taken with it. It has helped substantially with the coughing, although I haven't slept at all!!!"

Levocetirizine "I started taking Xyzal after a single episode of urticaria. I have had hand tremors for 40 years, severe enough to interfere with my work as a nurse. After 2 days, I noticed that the tremors were gone. To verify it was linked to the medication, I stopped taking it, and after 2 days, my left hand started shaking again, so I restarted it. It's been 3 weeks, and I am still free of any tremors."

Levocetirizine "I'm allergic to things that are both inside and outside on this planet. As far as I know, the only habitable planet that I have no choice but to stay on. My doc recommended Xyzal, I bought it the same day, then read the reviews. I wouldn't take it for 3 weeks after. Out of desperation and suffering, I started 5 days ago. I've slept for approximately 18 hours each day. (I work 12-hour days, so you can assume that I slept quite a bit at work.) When my alarm goes off, I start saying, 'You can do this! Get up, Shelby! Omg, why? Help!' After I wake, I wander around muttering, 'Why am I so tired? Something is wrong, I must be dying.' Not only am I sedated at all times, sleeping on floors and in my car, but I took my children to the park today and fell asleep on the picnic blanket for 2 hours. They could have been kidnapped."

Levocetirizine "I took one pill at night. I slept all night and all the next day. Do not recommend. I slept all day, so don't even know if it worked for allergies. Nowhere on the package did I see a warning about sleep problems and no additional instructions in the box. Stuck with an expensive product that I cannot use. In my mind, drowsiness is not the same as being sound asleep for over 24 hours."

"My doctor prescribed levocetirizine for reoccurring hives about 3 months ago. The first night I took a full dose (5 mg), I slept like a rock; didn't get up until the late morning. I now cut the pill in half, which has eliminated any drowsiness. It has helped the hives, and I haven't experienced any unusual side effects other than when I forgot to take it for a couple of days and started feeling nauseous. So if/when I no longer need it, I will stop using it gradually instead of suddenly."

Levocetirizine "This medicine has severe side effects; that is, it causes irritability and tiredness. It does dry a person out, but the side effects necessitate cautionary awareness if you are going to drive or work with people. You have no patience. I do not recommend this product."

Levocetirizine "I feel absolutely horrible. I ran out of Zyrtec, my son takes this, so I figured I'd try it. On day two, I feel a combination of having a concussion and a hangover all at one time. I'm fatigued, dizzy, and have a headache. This does not include the pressure I feel in my sinuses. I feel absolutely horrible. I'm done, I won't take this again. I'm honestly not even sure the FDA should have approved this drug."

Levocetirizine "Found this medication to be completely ineffective in treating my allergy symptoms. Not only was I up urinating many times during the night, but when I got out of bed, my eyes were tearing, my sinuses were swollen, and I was very drowsy. I believe this drug to be just another heavily promoted batch of promises that simply does not deliver. And yes, this stuff is not inexpensive to say the least. Save your money and just buy the home brand of antihistamine."

Levocetirizine "I have severe allergies indoors and out. I cough constantly due to post-nasal drip and an irritated throat. I took Xyzal, and within hours, the coughing stopped! I ran out of pills and took Allegra. The coughing came back the same day. The coughing doesn't go down well with everyone being fearful of the swine flu! I am so thankful to have found Xyzal."
