Dr. Reddy’s launches OTC Pataday generic in the US

Dr Reddy’s Laboratories has launched over-the-counter Olopatadine Hydrochloride Ophthalmic Solution USP, 0.7%, in the US market following approval from the US Food and Drug Administration, the company informed exchanges.

The product is the generic equivalent of Extra Strength Pataday Once-Daily Relief and is an antihistamine eye drop used for the temporary relief of itchy eyes caused by pollen, ragweed, grass, and animal hair or dander.

Dr. Reddy’s said the launch expands its OTC eye-care portfolio, which already includes Olopatadine Hydrochloride Ophthalmic Solution in 0.2% and 0.1% strengths. The company added that the first-to-market launch reflects its ability to bring store-brand equivalents of leading OTC products to the US and strengthens partnerships with retail customers.

The Pataday brand recorded US sales of about $70 million in the 52 weeks ended Dec 27, 2025, according to NIQ data.

The product will be available in a 2.5 ml bottle.
