Compare Zyrtec vs. Zaditor
Head-to-head comparisons of medication uses, side effects, ratings, and more.
Zyrtec (Cetirizine) is a once-daily allergy relief medication that won't make you feel too sleepy.
Zaditor (ketotifen) is the first-choice OTC treatment for allergy-related itchy eyes, but it doesn't treat infections and may not help for more serious allergies.
