Zaditor Eye Drops is an over-the-counter medication for the treatment of seasonal or year-round allergies. The active ingredient in Zaditor Eye Drops is Ketotifen, which is both an antihistamine and a mast cell stabilizer.

When the surface of the eye is exposed to allergens like ragweed, grass, or tree pollen, animal dander, dust mites, or molds, an allergic reaction can occur. This allergic reaction triggers the release of histamine, causing itchy, red, or watery eyes.

Zaditor Eye Drops provides triple action in relieving allergy symptoms:

• Antihistamine relieves itchy eyes in minutes
• Stabilizes to prevent itchy eyes for up to 12 hours
• Hinders allergic reactions by limiting the release of chemicals that cause inflammation

Some of the potential side effects of Zaditor Eye Drops can include burning or stinging in the eye, runny or stuffy nose and headache.
