Can it also be prescribed preservative-free?
3 Sep 2010
No there is not a generic alternative.-
Olopatadine ophthalmic solution (Patanol) is currently under the protection of a patent that prevents any generic versions from being manufactured in the United States. The first patent for olopatadine ophthalmic solution is currently set to expire in December 2010, although Alcon also has a patent for this medication that expires significantly later (June 2015). A few different manufacturers of generic drugs have challenged one or both of these patents, and Alcon has sued these companies for patent infringement. At this time, it is not clear when a generic olopatadine ophthalmic solution will become available, as not all of these lawsuits have been resolved.
