Olopatadine hydrochloride is an antihistamine (as well as anticholinergic) and mast cell stabilizer, sold as a prescription eye drop (0.2% solution, Pataday (or Patanol S in some countries), manufactured by Alcon). It is used to treat itching associated with allergic conjunctivitis (eye allergies). Olopatadine hydrochloride 0.1% is sold as Patanol (or Opatanol in some countries). A nasal spray formulation is sold as Patanase, which was approved by the FDA on April 15, 2008.[1] It is also available as an oral tablet in Japan under the tradename Allelock, manufactured by Kyowa Hakko Kogyo.[2]

It should not be used to treat irritation caused by contact lenses. The usual dose for Patanol is 1 drop in each affected eye 2 times per day, with 6 to 8 hours between doses.
