Olopatadine (Ophthalmic)

Olopatadine eye drop treatments work to prevent certain inflammatory substances from causing irritation of the eye.


Olopatadine is a prescribed eye drop that is used in the treatment of allergic conjunctivitis, which is commonly known as pink eye. The treatment works by preventing inflammatory substances that are produced by cells of the eye from having an effect. These substances commonly cause allergic reactions and lead to pink eye, but Olopatadine eye drops prevent this from occurring.

Olopatadine is available as a solution as either: Pataday, Pantaol or Pazeo.
