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® relieves tough allergy symptoms such as sneezing, itchy eyes, watery eyes, runny nose, itchy nose, and itchy throat. Take it at night for 24 hours of continuous allergy relief that won't fade into the next day.
