Since both medications have a common core chemical structure, Zyrtec and Xyzal generally have the same level of effectiveness, onset of action, and range of allergy symptoms treated. Xyzal is slightly less drowsy, so if drowsiness is an issue with your allergy medicine, Xyzal is better than Zyrtec.

The active ingredient in each Xyzal® Allergy 24HR tablet is Levocetirizine dihydrochloride 5 mg.

In an upscale study full of books, an animated owl, bedecked in a jacket and bow tie and wearing a monocle, suggests allergy sufferers try XYZAL. The medication, which may help with itchy nose, throat and eyes as well as sneezing, is available over the counter. “Be Wise All, Take XYZAL.”

The owl insists that XYZAL lasts six times longer than Benadryl, works faster than Claritin and provides the same relief as Zyrtec, but is only half the size. When he grabs the box of XYZAL Allergy 24HR on display with his wing, a security guard asks him not to touch the exhibit.

For mild to moderate allergy symptoms, Allegra or Claritin are preferred because they are non sedating and do not make you feel sleepy. For more severe symptoms that can interfere with work, school or daily activities, Xyzal or Zyrtec may be more effective.

Designed to be taken in the evening, so it starts working during the night and into the next day when pollen levels are at their highest. Get a good night's rest for a more productive next day, Xyzal® relieves allergy symptoms such as sneezing, itchy eyes, watery eyes, runny nose, itchy nose, and itchy throat.

Drowsiness is a common Xyzal side effect. It was reported by 5% to 6% of people taking the medication in clinical trials. Xyzal is more likely to cause drowsiness compared to some other second-generation antihistamines like Claritin (loratadine) and Allegra (fexofenadine).

Our Verdict. Xyzal is an antihistamine used to relieve a variety of indoor and outdoor allergy symptoms, as well as hives. A 24-hour over-the-counter allergy medication, Xyzal is safe and effective at the recommended daily dose, but it may cause drowsiness, according to the U.S. Food and Drug Administration (FDA).

Xyzal 5mg Tablet belongs to a group of medicines called antihistamines. It is used to treat various allergic conditions such as hay fever, conjunctivitis, some skin reactions such as eczema, hives, and reactions to bites and stings. It also relieves watery eyes, runny nose, sneezing, and itching.

Drowsiness, tiredness, and dry mouth may occur. Fever or cough may also occur, especially in children. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
