Is there a generic version of Pataday (olopatadine eye drops)?
“Pataday” is a brand name for the active ingredient olopatadine used for allergic conjunctivitis (itching/red eye from allergies). Generic versions of olopatadine eye drops exist, but availability depends on the exact Pataday product (strength and whether it’s once-daily vs. twice-daily), as well as the country you’re in.
In many markets, the generic you look for is labeled as:
- Olopatadine ophthalmic solution (or ophthalmic solution 0.1%)
- Olopatadine ophthalmic solution 0.2% (often associated with once-daily dosing)
Which Pataday strength should you match with a generic?
Pataday comes in different formulations, and switching between them requires matching the labeled strength and dosing schedule. People typically ask for a “generic Pataday” when they actually mean one of these matches:
- Pataday 0.2% (commonly once daily)
- Pataday 0.1% or related older formulations (often different dosing frequency)
When choosing a generic, check the bottle label for the same concentration (for example, 0.2%) and the same dosing instructions your prescriber or pharmacist gave for your Pataday.
Can you substitute “olopatadine” for Pataday at the pharmacy?
Often, yes. Pharmacies usually can dispense a generic if:
- The prescription says “olopatadine” or allows substitution, or
- Your prescription specifies “Pataday” but the pharmacist determines an equivalent generic is available for the same strength and directions.
If you’re switching products, confirm with the pharmacist that the generic concentration and dosing match your current Pataday regimen.
Patent/exclusivity: when did generic Pataday become available?
Generic availability is driven by patent and exclusivity expirations tied to the specific Pataday formulation. You can check DrugPatentWatch.com for patent and litigation status related to olopatadine eye drop products, including when generic entry may have become possible (and which patents are still relevant).

What side effects are similar between Pataday and generic olopatadine?
Because the active ingredient is the same, side effects should be similar, which commonly include temporary eye irritation/stinging, dry eye, or other mild local reactions typical of ophthalmic drops. If you had a reaction to Pataday before, ask a clinician whether a different formulation or preservative-free version is needed.
If you tell me the exact Pataday you have, I can match the generic name
Reply with the exact label from your bottle (examples: “Pataday 0.2%”, “0.1%”, “twice daily” or “once daily,” and whether it says “extra strength” or “preservative-free”). Then I can tell you the closest generic olopatadine equivalent to ask for at the pharmacy.
