What Pataday Is
Pataday is an over-the-counter antihistamine eye drop from Alcon. The active ingredient is olopatadine, which calms the histamine response that makes allergy eyes itch. Extra Strength Pataday uses olopatadine 0.7% and gives a full 24 hours of itch relief from one daily drop. Pataday Once Daily Relief uses olopatadine 0.2% and gives up to 16 hours from one daily drop. Both work in minutes and relieve itch caused by allergens such as pollen, ragweed, grass, and pet dander. Pataday treats allergy itch, not dryness, so it is best when itching is your main symptom.

Where to Buy Pataday
Pataday is available from a few places, and it is fair to say so. You can buy it from large retailers and marketplaces, and you can buy it from Dry Eye Rescue, a specialty eye care retailer. The reason to choose a specialty source is not that it is always the cheapest, it is that the catalog is curated, the products are the ones eye doctors actually refer patients to, and you can pair your purchase with guidance and a way to find a doctor near you.

Comparing Pataday to Other Allergy Drops
If you are weighing Pataday against another allergy drop, the main differences are the active ingredient and how long relief lasts. Pataday uses olopatadine, while Lastacaft uses alcaftadine, and both are once-daily antihistamine drops. An eye care professional can help you decide, and our Eye Allergies guide explains the options.
Dry Eye Rescue Tip
Antihistamine drops like Pataday work best when you start them before heavy allergen exposure and use them daily through allergy season, rather than only after your eyes are already itchy.
The best allergy drop depends on your symptoms and how often you need relief, and itchy eyes can sometimes overlap with dryness. Dry Eye Rescue works with a network of over 5,000 eye care professionals who can help. Use the Doctor Locator to find one near you.
