Pataday Once Daily Relief Extra Strength is indicated for the temporary relief of itchy eyes due to pollen, ragweed, grass, animal hair and dander.

The investigational nasal spray contains varenicline, a highly selective nicotinic acetylcholine agonist.

The over-the-counter product may be used as a protectant against further eye irritation and to relieve dryness of the eye.

The approval was based on data from two randomized, multicenter, double-masked, vehicle-controlled trials that evaluated the efficacy and safety of Verkazia in patients with VKC.
