"Will not take again! Up all night, frequent urination. Finally fell asleep and woke with awful migraine, dizziness, nausea, fatigue, and muscle pain! I've been feeling awful all day! Can't wait to get this out of my system! Will go back to Claritin, which I tolerate. Ughhhh..."

"I think I have chronic sinusitis, with allergy symptoms all day long, year-round. Zyrtec used to help, but doesn't anymore. I thought that Xyzal was going to be the answer, and it was until I started experiencing stomach aches that had no apparent cause in what I had eaten. Very reluctantly, I stopped the Xyzal, and the stomach aches stopped. But if you don't experience any of the side effects, then it works better than any other medication for allergies that I have ever taken!"

"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."

"Have been taking it for 2 weeks for seasonal allergies, and I have had no itchy or watery eyes like I typically do this time of year, but…the side effects! Extreme fatigue, almost to a depressed state, already gained 3 pounds in 2 weeks, and have random acne all of a sudden. Definitely stopping this medication."

"I have learned my mistakes with taking Xyzal. It gave me horrible side effects, but not only me, but some of my family. I currently am trying to get over a really stuffed nose and bad coughing. I had to look up to see if I wasn’t the only one, and apparently I wasn’t. I can see why the pharmacist said Allegra was better. It only worked in the beginning when I took it, then side effects started to kick in."

"Very good for my hive allergy symptoms. Almost works for the whole 24 hours... very nice. Yeah, it might make me hungrier... so I eat another apple - ha ha, it's all about your food choices. I'm glad this exists. I'm on allergy shots, so it doesn't always clear 100% of my misery, but it's close enough. Way better than other medicines - I've tried so many."

"This has been one of the worst medications for allergies that I have ever taken. I took it around 5 a.m. in the morning, and right now it's 6:45 p.m. My nose has been draining since I took this medication, and I'm more stuffed now than I've ever been. My eyes are watery, and I'm sneezing something terrible. I do not recommend this medication. Save your money and try something else. By the way, this was my second time trying it just to see if I would have the same symptoms, and I did."

"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."

"This drug was fantastic at kicking my allergies to the curb. It even kept my eczema flares at bay, and my skin was completely clear. I was very excited about this OTC drug until... Every night I had vivid dreams and woke up drenched in sweat. Lo and behold, the dreams and the sweats stopped as soon as I stopped taking this drug. I tried halving with no luck. I talked with a few pharmacists, and they've not heard this report before, but I thought I'd prove well to tell others. It may not be enough for some people to stop taking Xyzal, but I could not handle it. It is in the same class as Zyrtec, which I can tolerate, so this was strange. Still, I am sad because it is a very good allergy drug and why I rate it highly."

"Within 2 hours of the first pill, I got great relief. Zyrtec wasn't working well. The 24 hours after the first Xyzal were the first almost normal day I've had in months. I went one hour past the 24 before taking a second dose and started symptoms again, and now an hour later I can feel it starting to shut down the itchy, runny nose and throat. All I can say is hooray for Xyzal because my life this spring has been a total misery because I can no longer use corticosteroids that helped a lot (like Flonase, Nasacort, or Flovent for asthma) due to having developed glaucoma. I have tried Nasal Crom and ProAir (albuterol) at my doctor's suggestions along with Zyrtec, but they were doing little or nothing."

"I started Xyzal in late August due to repeat sinus infection and allergies. Last week, I skipped two doses by mistake, and that was the worst thing that I could have done! I had a full-blown panic attack in the truck while on our way home from running errands. I literally jumped out of the truck while it was still moving because I felt like my head was about to explode! It was the worst day ever. I am now only taking half a tablet to wean myself off this drug. Had I known these severe side effects after wanting to stop them, I never would have started them. Since halving my dosage, I have been having anxiety, joint pain, itching, and swelling in my sinuses. I am hoping to be off of these within 2 weeks since I only took them for around two months."

"I have been on Xyzal for 2 of the worst months of my life. It relieved sinus headaches. But had nightmares, tingling in my feet and legs. Abnormal glucose blood work, which is back to normal now. Depression, terrible anxiety, extreme hunger. Thank you all for your honesty. No more Xyzal for me."

"After only one dose, in the evening, I have felt sedated for 3 days now. My grandson took Xyzal at bedtime 2 nights, with sedating effects that left him on the couch and sad. We stopped Xyzal and started Allegra, and he is acting like himself again."

"I've had such a mixed experience with this drug. On the one hand, it kicked a sinus allergy-induced migraine I had for days that hadn't responded to other medicine. Once I started taking it on a daily basis, however, it made me extremely tired and sore. I tried taking halves, and it isn't so bad that way, but ultimately led to a lupus flare, which made me realize it was having a stronger effect on my body than I'd realized. Now missing work from it. Take with caution!"

"The first 2 bottles I bought were amazing. I took them at night as indicated; slept well and no morning 'hangover,' and best of all, no allergy symptoms. The 3rd bottle, however, feels as though I haven't taken anything. I have been taking medication from this bottle for approximately 2 weeks. Not sure if I got a bad batch or what. I will buy a smaller bottle next time just to make sure."

"I have been taking Allegra for 25 years for allergies and asthma, and the doctor recommended I switch to Xyzal. I only purchased a small package of 8 because I wanted to make sure I did not have any adverse side effects. Many years ago, I had taken Zyrtec and had horrible dreams at night. Well, last night was my 7th day on Xyzal, and my dreams were horrible. I woke up screaming at one point because I thought someone was attacking me and my boyfriend in the bed. As far as allergy symptoms go, this helped tremendously. But I cannot handle those kinds of dreams and feeling like I am not getting sound sleep. I will have to go back to my Allegra."

"This is the first allergy medicine that has completely worked for me. I haven’t experienced any allergy symptoms since I’ve been taking it. I’ve had allergies for years and literally cannot go outside during high pollen count days, especially during April and May. Since taking Xyzal, not only can I enjoy sitting outside, but I literally had no symptoms at all. I have had no side effects at all. It is also very convenient to take it at bedtime."

"I took Xyzal for a couple of months, stopped and restarted this spring. Since restarting, I was getting more fatigued and achy, little by little, with almost a drugged/hungover feeling most every morning. It would take me until late afternoon to feel somewhat functional. I chalked this up to other issues (hormonal, life changes, work stress), but then stumbled upon something that discussed such side effects with allergy medicines. After doing extensive research, I've found these effects are not as uncommon, or random, as they first appeared. After stopping about two weeks ago, I don't have the exhaustion, body/joint pain, and drugged feeling every morning. It has been a marked, and remarkable, difference. Granted, I still have allergies...but I'll gladly take those over feeling like I was 137 years old. I was getting afraid that something else was happening or that if this was just 'aging,' I wasn't going to make it much longer! I'm feeling much better now this medicine is out of my system."

"I gave it the benefit of the doubt after the first few times it stopped working. This last time, last night to be exact, I took one before going to bed. I woke up this morning like my nose was a faucet. This is the most frustrating medicine ever... and since it is 24 hrs, now I have to suffer ALL DAY before I can take something else."

"Started taking it in 2017 after the owl ads on TV. It does work, and it does produce a mild tiredness hangover effect the next day-though it is less pronounced than Benadryl's next day hangover. I took one tablet a day for a month and started noticing the hangover getting stronger, so I cut down to half a tablet. I started noticing a very quick and aggressive angry response from me to any type of provocation or annoyance-yikes! I stopped taking it immediately after noticing this side effect after 2 months of taking it. I now take a 1/4 tablet with a Mucinex, when allergies flare up, and this seems to work better with no pronounced anger or hangover."

"I’m giving this medicine 2 stars because it worked the first couple of times and then went downhill from there. I feel like my body got used to it so quickly because I have suffered from allergies as a kid or my allergies are just that bad that the pill doesn’t work anymore. I have even taken two pills in desperation to help before the 24 hours, and NOTHING. Save your money."

"I normally take allergy meds, and I tried this about 10 years ago. It did not work for me. I decided to try it again yesterday, and it really worked on my allergies, but I had the worst nightmares and was tossing and turning all night. Then, all day today, I have felt sick to my stomach and have felt dizzy and have not been able to take a nap or anything. Finally, it is starting to wear off after about 20 hours from the time I took it."

"I have one kidney that I have had two surgeries on, so if I feel pain in my side from a drug, I have to stop taking it. I finally found Xyzal, which works great, but I get heart pain from it. I didn’t realize until the second year I took it for seasonal allergies. Then I finally put it together."

"Though I can't say anything about the long-term effects of this drug, I can say that I get no relief from most allergy relief medications. I've been taking Zyrtec with no noticeable difference in the relief of my symptoms. And Xyzal seems to be helping quite a bit. Although I have very bad seasonal allergies, so I'd be surprised if anyone ever made anything that would completely get rid of them."

"I started taking this medication less than a month ago for seasonal allergies since my daily Zyrtec was not effective. I took the first dose before bed, and it was great at helping me sleep better, and I felt great the next day; symptoms weren't 100% gone but much better. Then, after a few weeks, the effect wasn't as great as Zyrtec (when it worked), and then came the side effects. Despite giving relief and improvement to already good sleep in the beginning, a month in, my allergies have gotten worse. I have possible side effects (grogginess all day, lack of appetite, malaise, scratchy throat, and fatigue). Heading to the second doctor visit today and not continuing this medication considering this is the only medication I am on, and despite having allergies, I felt far better before being on it."
