Drug Description


Pataday is an eye drop medication that is used to treat the symptoms of seasonal allergic conjunctivitis, or eye allergies. Its active ingredient is called Olopatadine. Olopatadine works quickly to reduce itchy, watery eyes, sneezing, and nasal congestion due to both indoor and outdoor allergens.

Pataday is a prescription medication used to treat the symptoms of seasonal and perennial allergies. It is a once-daily eye drop that provides quick, long-lasting relief from redness, itching, burning, and watery eyes. Unlike other allergy medications, Pataday works quickly without needing frequent dosing or the need to take additional oral medications.
