"The very first day I took this medicine, it felt like someone was squeezing my brain. I don't know if my sinuses were that bad or this medicine was a contributor. After reading these reviews, I would not buy or use this product again, and plus, it's way too expensive. I wish I could have given it a 0 rating because a 1 is way more than what they deserve!"

"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."

"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 allergens 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 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 breathe. 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 every day 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."

"I took this pill at bedtime twice, and it kept me awake until after 2:00 a.m. I woke up with worse symptoms than I had before I took the pills. When I woke up, I was stuffed up, and I stayed that way all day long. I also had lots of coughing - unlike my normal cough that is due to post-nasal drip. I also have a bad sore throat. On both Saturday and today, I have tiredness, and I am unable to function. I will go back to my normal medicine in the morning. These pills were a waste of money."

"I have a rare skin rash that appears only during the 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 immunosuppressive reaction occurred. I started getting large, painful pimples in weird places like the forearm, hand, and neck. Had a similar reaction to Flonase a few years ago. The 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."

"I took Xyzal last night for the first time. I have awoken with the left side of my nasal passages blocked and a headache that feels like a benzo hangover. If I'm going to feel this way the morning after, I better have had fun the night before. 1/10 I will never take this again even though it was free."

"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 three 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 of symptoms with certain medications, avoid Xyzal."

"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 nowadays' 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!"

"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."

"My doctor suggested this medication for allergies a few days ago. I was taking it for two days, and I was completely 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."

"If you have a history of mitral valve prolapse or tachycardia, do not take Xyzal! I took this for three days and ended up having AFib. My doctors dismissed the possibility of the Xyzal causing this, even though it was the only change in my routine. I was put on Toprol, Eliquis, and Multaq to treat the AFib and referred to an electrophysiologist for a possible heart ablation. Since they said it was not the Xyzal causing this heart problem, and I started suffering from my allergies again, I decided to take it again. A few hours later, I began having palpitations. The risk of palpitations, tachycardia, and AFib should be included on the label!!"

"So I have terrible allergies, which most people on here say they do. I typically use Claritin and Zyrtec. I switch the two every other month. Also, I use allergy shots (three 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 ten-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 haven't 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. Benadryl and Allegra do nothing for me."

"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 can sleep at night and wake up without an itchy throat. No more constant sneezing, coughing. I can finally go outside and enjoy the springtime. I have read other reviews of people being tired the next day, and I haven't experienced that."

"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 Xyzal the night before makes so much sense. As far as helping with my allergy symptoms, not so much."

"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."

"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 20 mg 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."

"I have used a lot of different allergy medicines (for dust/mold/pollen), and I have never gotten a side effect as bad as I got from this. I switched from Zyrtec to this because of a discount that was given; I have been on it for close to 10 months, and then I started losing my short-term memory, losing creativity, and it even started to make me slur words. I don't blame it entirely on this medicine; it may have been the combination of this and Astepro, but in my experience, this definitely causes drowsiness. I can't completely say to stay away from it; just be sure to monitor it right away and after about 5 months. I switched to Allegra 180mg. Hope this helps."

"This pill did help my allergies, when Claritin and Zyrtec didn't, but the anxiety I had after a day was the worst I had ever experienced. I have frequent panic attacks, so I know the feeling. I almost went to the ER one night. Since stopping, anxiety is back down to normal levels. Unfortunately, the relief isn't worth it."

"I started taking this as my allergies were out of control this year and nothing else seemed to work anymore. It worked great at first, then after about 3 weeks I started getting irregular heartbeats and the overall feeling of anxiety, which brought me into the ER since the symptoms were getting worse with a rising heart rate. After about a week off the meds, I am feeling much more normal again. Very scary when an allergy med affects your heart rate! None of the others I have ever taken gave me this feeling."

"Xyzal was prescribed for my daughter by her allergist for abdominal pain and bloating, with hives and an 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 years old. She currently complains 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."

"As far as allergies and itchiness, it has helped tremendously, but the dreams are absolutely deranged when I take it. Violent, and I wake up angry. You would think I was a nutcase, but I swear I do not have these dreams otherwise. Worth it? Idk. During the day it certainly is, but not sure about the trade-off at night. And I just take one tablet."

"For allergies and allergic reactions, this medication worked well. Benadryl had stopped being effective, and Claritin has always been useless, so I decided to give this a shot. I took it around 5 p.m., and within an hour, the misery of the allergies was less, and by morning, I felt 100% better. I took the product for two weeks until whatever was triggering my allergies finally stopped. No side effects noticed while taking the medication (which for me is rare as I'm allergic to nearly everything). No problems with interactions with heart medication either. Was well worth it."

"Best allergy medication I have tried in 10 years. No drowsiness, no side effects. It's working perfectly. I take one a day, at night, just as it states on the bottle, and it's working perfectly. Every once in a while, I have to take a Sudafed for a little nasal drip when allergies are severe, but that's rare."

"I normally use Zyrtec liquid gels - the tablets are nowhere 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."
