User Reviews for Xyzal oral

This stuff left me dangerously sedated. I took it 19 hours ago and am still way too impaired to drive and too unsteady to stand up in the shower. Worst drug ever.

This is the only medication that has proven effective for my allergies. Claritin had no effect. Zyrtec and Benadryl at night had some effect. This on its own is highly effective for me,it does cause a deep sleep and drowsy hangover in the morning. Perhaps this will subside as my body becomes used to it. I also use this with Flonase and a Nett Pot... But will be cutting Flonase now too.

I recently started taking this drug for seasonal allergies. I am convinced it is the cause of the sore throat, and stuffy nose that have led to a full-blown sinus infection that antibiotics isn’t curing. Check the known side effects. You will be shocked.

Since they offered a "free" sample, I thought I'd try this medication in hopes of finally finding something that works well. Sadly, it does not work for me at all. Had been taking Costco's version of Zyrtec, which was working fairly well. Switched to Xyzal and have NO relief from ANY of my symptoms. I woke up this morning sneezing my head off and nose running like a fawcett. This is my 3rd day on this medicine. NO EFFECT, including no drowsiness. Still have runny nose, sneezing

Was prescribed by my ENT physician. Had dizziness and slight headache throughout the day. Other allergy meds did not have this. I will not finish this bottle.

Started taking it for my seasonal allergies in 2017 after the owl ads on TV. It does work in a subtle way 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.Read More Read Less

made me feel drugged all day and had no effect whatsoever on my allergies. Worthless product.

Terrible drowsiness about 18 hours after taking before bed. Effective antihistamine; but side effect of prolonged drowsiness is unacceptable. Would not be safe to operate a vehicle or even walk on uneven ground.

Severe mode altering side effects and tiredness. Do not use this if working with people or driving. Causes impatience and irritability. I do not recommend this drug.

Has caused me urination problems and after ten days have had to stop. Other wise extremely effective.

I try many different allergy medications. This is the only one works for me.

I gave this medicine to my 9-year old. I started his dosage at 1/2 tablet, increased the dosage to 1 tablet, then finally increased the dosage to 2 tablets. He never experienced any relief from his allergy symptoms with this medication. It cost me 19.99 for 35 tablets. What a waste.

Nothing makes me sleep. Im immune to everything except this. This left me dizzy and tired all day. I am surprised I did not crash my car going to Target. I suggest not taking this on days you need to be alert until your body becomes accustomed. They should market this as a sleep drug for this gave me my first deep sleep in 20 years

Xyzal just recently became OTC. Previously I used Zyrtec and Chlortrimeton. 5mg Xyzal seems better than 10mg Zyrtec. I have been taking 1 or 2 5mg Xyzal since it became available this spring and so far find it to be best antihistamine available OTC. It seems to be similar to Zyrtec but a bit stronger and has the same drowsiness profile. I have not experienced any of the negative side effects.

Took this medication one time for allergies after mowing the lawn. Next day went for regular checkup and found my heart rate was 163 with blood pressure at 90/60. Doctor immediately sent me to the ER to get some fluids and test to find out what was going on. After dose of Cardizem, heart rate slowed and has remained within normal range. After checking online for possible side effect stating rapid heart rate was one, have decided I will not take this again! ER couldn't find any other reason for the rapid heart rate.Read More Read Less

Extremely tired, even after cutting dose to half. Feel like a zombie with only 3 days of taking this med.

Took the once a day pill for the first time today. Bought a 35 count package today at Walmart. Have had it in my system for about five hours and I'm still have a runny nose, sneezing, and watery eyes. I'm very unsatisfied.

I am sensitive to drugs that cause drowsiness. I started taking XYZAL as I was getting over a cold, and I did not realize at first that the drug was making me weak and tired. Now that I have been over my cold for more than a week, I'm still finding myself having a hard time waking up, groggy all day, and sleeping away the afternoons. I wish I had never started XYZAL - now I have to wait the rest of the 24 hours to get it out of my system so I can wake up!

Have been on this for years and I did allergy shots for 8 years and this is amazing! Does take a bit to work..but now..I'd never run out because it works so very well. No loss if it doesn't work for you. I had tried all prescription gallery meds previously, then shots and this works the best.

I've been diagnosed with hives of unknown cause (for two months already) and this medicine works. Around 95% of my hives have disappeared and there are no side effects for me. The downside is that it is not a long term cure. If I don't take them, after 2-3 days the hives appear again, the same as before. So I'm kind of dependent on them.
