Eye allergies are very common. In fact, one study suggests as many as 31.5% of Americans have reported suffering from symptoms consistent with eye allergies at least seven days out of the year.1 Many people experience itchy, red or watery eyes, which are symptoms of a type of eye allergy called allergic conjunctivitis.

Allergic conjunctivitis can occur at any time, but it’s most prevalent during the spring and fall as a result of seasonal allergies. Perennial allergic conjunctivitis persists throughout the year, but can get worse during certain seasons. It’s caused by exposure to constantly present household allergens such as animal hair and dander, mold or dust.

Seasonal allergies are caused by allergens that are released during pollination. The most common allergens that cause seasonal allergies are tree, grass and weed pollen.

For effective treatment of itchy eyes caused by seasonal and perennial allergens, there’s over-the-counter ZADITOR® Eye Drops. It’s the first over-the-counter allergy eye drop strong enough to last up to 12 hours with just one drop.

What causes eye allergies?

Eye allergies are caused by an exaggerated immune response to relatively harmless substances called allergens. Common allergens that cause eye allergies include pollen, dust, mold, animal hair and dander. When these allergens come in contact with the surface of the eye, an allergic reaction occurs. This releases histamine that causes the irritating symptoms associated with eye allergies.

What are the symptoms of eye allergies?

Itchy eyes are the most common symptom of eye allergies. Other symptoms may include redness, swelling, or watering.

What are the different treatment options?

Eye allergies can be treated with antihistamines, decongestants, and anti-inflammatory agents. These are available as both over-the-counter and prescription medications.

ZADITOR® Eye Drops provides fast, long-lasting relief of itchy eyes caused by allergens. Previously available only with a prescription from a healthcare professional, ZADITOR® Eye Drops is available over-the-counter in its original prescription strength. It relieves itchy eyes within minutes and lasts for up to 12 hours with just one drop. And ZADITOR® Eye Drops is the first over-the-counter itchy eye treatment that’s safe for children aged 3 years and older.

Many over-the-counter medications that treat itchy eyes contain vasoconstrictors. Vasoconstrictors (decongestants) reduce the redness in the eye by narrowing the blood vessels in a process known as “vasoconstriction.” With overuse, vasoconstrictors can cause rebound redness, leaving the eyes red for a period of time after discontinuation.2 ZADITOR® Eye Drops treats itchy eyes without a vasoconstrictor, so rebound redness is not a concern.

If ZADITOR® Eye Drops does not fully meet your needs, please talk to your doctor about prescription strength relief.
