For Allergic Rhinitis "I have seasonal allergies and decided to try Xyzal, taking 1 pill at bedtime. It worked well for my allergies, but I woke up feeling groggy and fought drowsiness all day. By the afternoon, I took a 2-hour nap. It’s evening now, and I still feel wonky. I think I’ll stick to Claritin."

For Allergic Rhinitis "I have been taking Xyzal for 2 days now. I have had a constant post-nasal drip since I quit smoking about 6 months ago. Tried EVERYTHING from humidifiers to nasal rinses, Mucinex and Sudafed, steroid nose sprays, and elevating my head. I've been to the doctor multiple times with no answers, and this is the only thing that makes it not feel like a lump of gunk isn't stuck in the back of my throat. I have been so miserable coughing up nasties every night. The downsides: gives me heartburn (a lot of things do, so it's not a surprise), so I have to take Tums with it. It also makes me VERY drowsy, so I take it an hour before bed and then go to sleep."

For Allergies "I was prescribed Xyzal by an ENT to relieve symptoms of a sinus infection, along with an antibiotic and the nasal wash Xlear. I noticed that I slept exceptionally well while taking it, so I decided to add it to the supplements I take to ameliorate 4 a.m. awakening caused by what I believe is Advance Sleep Phase. I began to become aware of feeling foggy-brained, and it was difficult to ascertain what was causing it because my levothyroxine levels had been lowered by my doctor; subsequently, my blood pressure then became quite low: 110/62. After reading of the effects others have felt, I now believe Xyzal has caused the irritability and drowsiness I have experienced of late."

For Allergies "I started taking Xyzal about a month ago, per my allergist's suggestion. All was well for a couple of days. No more stuffy nose and itchy eyes. I noticed that I was sleeping more, like getting 9-10 hours of sleep, but needing a 2.5-3 hour nap. I normally get 7 hours of sleep a night. At first, I didn't pay much attention to it. I am training to run/walk a 5K, so I thought that I was overheating or getting dehydrated. I moved my exercise times to sunset, but that did not help my sleepiness. For 3 weeks, I was drowsy all the time and had little interest in anything other than sleep. So now, I'm on my third day of not taking Xyzal. My symptoms have returned, but I feel more awake and like my old self. I don't mind a power nap, but wanting to sleep the day away was not good. I plan to switch to a different allergy tablet once my energy levels get back to normal."

For Allergies "Seemed to work pretty decently for my allergies, but the sleepiness was too much to handle. I felt really weird and out of it on just half a pill. I had pretty bad headaches too."

For Allergies "Took Xyzal at 8:00 pm last night, and it is now noon the next day, and I am still having trouble keeping my eyes open. The box warned it could cause drowsiness, but I am beyond drowsy-extremely tired."

For Allergies "The drug seems to work, but it made me so dopey and sleepy that I couldn't take it. It made me feel like I was on actual drugs. Disappointing."

For Allergic Rhinitis "This is the best med for allergies ever! It will cause some sleepiness, so I wait until I'm at work, take the Xyzal, and drink one cup of coffee. Talk to your allergist about this stuff!"

For Allergies "Tried the whole line of meds, Allegra, Claritin, and so on. Xyzal works the best for me, it does not make me drowsy, give the shakes, or any of the side effects I get from Benadryl."
