Get fast, targeted relief from itchy, irritated eyes with SYSTANE ZADITOR Antihistamine Eye Drops. Specially formulated for eye allergies, these prescription-strength antihistamine drops provide temporary relief from itching caused by common allergens including pollen, ragweed, grass, animal hair and pet dander.

Fast, Targeted Relief for Itchy Allergy Eyes
Eye allergies can quickly become uncomfortable, particularly during pollen season or when you’re regularly exposed to pets and other environmental allergens.
Unlike general allergy products, SYSTANE ZADITOR is applied directly to the affected eye, delivering its antihistamine active ingredient exactly where it’s needed. The formula targets allergy-related itching to provide effective, long-lasting relief.
With relief lasting for up to 12 hours, there’s no need to repeatedly apply drops throughout the day.
Prescription-Strength Formula Without a Prescription
SYSTANE ZADITOR provides prescription-strength antihistamine eye allergy relief in a convenient over-the-counter format, so no prescription is required.
It’s an ideal addition to your allergy-care routine if you regularly experience itchy eyes due to:
- Pollen
- Ragweed
- Grass
- Pet hair and dander
- Seasonal allergens
- Everyday environmental allergens
Its compact format also makes it convenient to keep at home or take with you to work or while travelling.
Up to 12 Hours of Allergy Itch Relief
One of the key benefits of SYSTANE ZADITOR is its long-lasting action. A single application can provide relief from allergy-related eye itching for up to 12 hours.
This makes it particularly useful during periods of increased allergen exposure, such as spring and summer pollen seasons or when spending extended periods outdoors.
Suitable for Adults & Children Aged 3+
SYSTANE ZADITOR Antihistamine Eye Drops can be used by adults and children aged 3 years and over when used according to the package directions.
For allergy-related eye itching, place one drop into the affected eye(s) twice daily, approximately every 8–12 hours. Do not use more than twice per day.
