Xyzal (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 Xzyal for me."

"I've had allergies all my life, and they get especially bad in the summer. I get completely stuffy and I can't breathe from my nose at any time, regardless of what I am doing. If I take this, they get a better, but not completely gone. My doctor also added Fluticasone and now my allergy symptoms are completely gone. Claritin-D, Allegra-D and Zyrtec-D just didn't help."

Xyzal (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."

Xyzal (levocetirizine) "I took this three days ago and was up all night. I didn't make the connection as I had a cup of coffee later in the evening than I normally would. I took another Xyzal the following day. I still have not slept. I have been up for 3 nights!!! I have a heavy duty sleeping pill that I am going to take tonight and I'm hoping that will be the end of it. I can't imagine it would take longer than 72 hours to make its way out of my system. If you are someone who experiences these types symptoms with certain medications, avoid Xyzal."

Xyzal (levocetirizine) "Healthy adult male, slightly overweight, itchiness from allergies. Half a tablet left me groggy and exhausted for nearly 30 hours. Also some minor chest pains. I cannot risk using it again. It got rid of the itchiness, but the side effects are a big negative"

Xyzal (levocetirizine) "I have severe allergies indoor and out. I cough constantly due to post nasal drip and 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."

Xyzal (levocetirizine) "I have had the worst allergies on record this season. I have tried everything from Claritin to Zyrtec and everything in between. Nothing helped. My post nasal drip was so bad I felt like I had bronchitis from all of the coughing. I even thought I was going to overdose on my albuterol inhaler because I used it so much because I could not breath. A friend recommended Xyzal and brought it to my house one day. The symptoms did not go away all at once but after 2 days on the pill I feel so much better. I take it around 6 pm everyday and I sleep well and wake up perfectly fine the next day. Xyzal has saved me. I hope it lasts and doesn't wear off like Claritin."

Xyzal (levocetirizine) "I never tried this product because I am allergic to microcrystalline cellulose. The cellulose can cause gut pain, inflammation and sometimes itching. Watch for products that use this filler. Even some prescription drugs use this filler. Be aware of the inactive ingredients in what you take."

Xyzal (levocetirizine) "The instructions say that you should take it at night as it can cause drowsiness; however, this medication kept me up all night! It also made me feel anxious and weird. And to top it all off, I am still suffering from allergies. Guess it's time to try something else."

Xyzal (levocetirizine) "I have a rare skin rash that appears only during summer months. It is an immune system response to heat. Xyzal 10 mg reduces the rash by about 20%, but after about a month, an immunosupressive reaction occurred. I started getting large, painful pimples in weird places like forearm, hand, and neck. Had a similar reaction to Flonase a few years ago. Immune system can't fight the pimples, so they take over. Disappointing because this is the first oral drug to have an effect on the rash. Hay fever gone too."

Xyzal (levocetirizine) "My doctor suggested this medication for allergies a few days ago. I was taking for two days and I was completed exhausted and wiped out both days (which never happens to me). So I decided to research it and saw that many people had a similar reaction. This was a significant reaction so be careful before you take it. I have now stopped."

Xyzal (levocetirizine) "I started using this right after starting immune therapy for indoor and outdoor (perennial) allergies. I had been on Zyrtec and the additional dose of allergans coming from the shots made me miserable with continual sinus mucus draining/blowing; I tried taking Benadryl (on top of the Zyrtec) but that put me to sleep. The Xyzal stopped the allergic reaction, so I'm on it now for the second month with no side effects; and very happy to have it."

"I am a healthy, stable person. I took this for seven days. It was instantly effective at treating my allergies all night and day and helped me sleep at night. However, during the days I started having moments of fogginess in my thoughts and physical tiredness that were intense..too intense as I drive an hour commute to university. One day in class I felt confused about what time it should be on the clocks and what time events in my day normally occurred. I felt panicky, confused and out of my body that day. That was the last day I took it. I am sensitive to medications including anything that CAN make someone drowsy. Maybe I could lower the amount I take but for now I'm just going to be more consistent with meds I trust and that don't make me feel anxious, detached and exhausted. Overall I think it's effective and worth trying. It just didn't work for me because negative side effects outweighed the benefits."

Xyzal (levocetirizine) "I have chronic sinus allergies and my ENT prescribed Singulair and Allegra 180 mg one tab each per day. These worked fine for me, but my Doctor then asked me to try Xyzal instead of the Allegra, I've been using this new combination for about a month or so, but for me, the Allegra may be more effective, and I don't get the "drowsies" from it as I get with Xyzal. I then did something stupid, I tried being my own doctor, and took (2) Xyzal tabs with my usual 20mg of Singulair. The result being INCREASED histamine and drowsiness... so folks, the moral here is; Don't play Doctor,... abide by your Doctor's instructions... he/she knows best."

Xyzal (levocetirizine) "This medicine has helped me through allergy seasons, hives, and hay fever. Most of my family uses it, too. My dad is 56 and he loves it. He goes on and on about how "medicine is so advanced now-a-days" and how it was "back in his day". He says he has never seen anything like it and swears by it. I do, too. It's great!"

Xyzal (levocetirizine) "It worked great for me. I get hives and become really itchy near dust. I thought everyone was itchy all the time but it turns out it wasn't normal. The doctor said to take this. It hasn't made me tired or have any mood changes. Though there are barely any medicines that do make me drowsy."

Xyzal (levocetirizine) "So I have terrible allergies, which most people on here say they do. I typically use Claritin and Zyrtec. I switch the 2 every other month. Also I use allergy shots. (3 shots every time, which sucks!) Some co-workers of mine mentioned using Xyzal and having good experiences so I decided to try it out. I decided to get the 10 pack first just to try it out since it's so expensive. As far as helping my allergies... the medicine has helped me a lot. The downside is it makes me extremely tired. Basically I better be ready for bed soon after taking it. But I having had any grogginess the next morning. I just wake up feeling really good. But keep in mind, what works for me may or may not work for you. Benedryl and Allegra does nothing for me."

Xyzal (levocetirizine) "I normally use zyrtec liquid gels- the tablets are no where as effective. But they last only about 3 hours. This stuff made me a little groggy, but not when I wanted to sleep, and if it had any allergy effect it was indistinguishable from nothing at all. Waste of money- I had so wanted a longer lasting alternative - NG"

Xyzal (levocetirizine) "BAD EXPERIENCE FOR ME. First side effect was tired. Turned into totally wiped out. Lack of energy, feeling sore, then the sore throat! This drug kicked my butt. It's not for me, I want to be outside active.. This drug will keep you on your sofa..... I'm going back to my old faithful. I tried this because of the coupons."

Xyzal (levocetirizine) "Wow, so glad I found these comments! I couldn't figure out why some days I feel like a zombie and have to go back to bed. Linking this with when I've taken Zyzol the night before makes so much sense. As far as helping with my allergy symptoms, not so much."

Xyzal (levocetirizine) "Xyzal was prescribed for my daughter by her allergist for abdominal pain & bloating and with hives and itchy mouth after certain foods. Symptoms getting worse over 5 years. Started whole tablet for 3 nights before cutting it in half due to severe drowsiness and slow response time. Ugh. She weighs 105 lb and is 22 yo. She currently complaints of being horribly fatigued all day after 12 hours of sleep. Senior year in college begins next week. Bloating is still occurring as is abdominal pain."

"I took the med levocetirizine since I have allergies. I took it for 3 days straight but stopped since I was not feeling well. Went two days without it and then took it again because my allergies were still bothering me. I woke up the next morning after taking it and realized I cannot smell or taste anything, and my nose and headache pain for work. It has got to be this medicine. I will not take it again."

Xyzal (levocetirizine) "My allergies are terrible, it doesn't matter the season. I have tried Claritin, Zyrtec, you name it I've tried it for my allergies. I finally came sleep at night and wake up without an itchy throat. No more constant sneezing, coughing. I can finally go outside and enjoy the spring time. I have read other reviews of people being tired the next day and I haven't experienced that."

"Levocetirizine 5mg was prescribed by my doctor for my nighttime watering eyes and runny nose allergies. I asked if it had any bad side effects and she said it didn’t. I take no other meds for anything so it was easy to realize why I suddenly was too tired to function and not my happy go lucky self who used to have energy! My husband thought I was developing dementia! I didn’t take it last night and today I am myself again! I WILL tell my doctor next time I see her. Thank you for the reviews that helped me understand what was happening to me!!!!"

Xyzal (levocetirizine) "First time using Xyzal last night for allergies. Normally, I take Benadryl but wanted to give this product a try as it's new OTC. I only took half a pill at bedtime. Yes, my allergic symptoms cleared up but WOW did it make me tired. I'm thankful I have the day off as I don't know how I could function at work. I expected some drowsiness but this far exceeds the effect of a full dose of Benadryl."
