Zaditor (ketotifen): Zaditor seems to be more effective in my experience. Both of these are less effective than prescription alternatives (pataday, lastacaft, (alcaftadine) etc).

Equivalent: Both of these are anti-allergic drops which due to a terrific safety profile, have been released for over the counter distribution. There is little to choose between each of these.

Yes: Zaditor (ketotifen) is longer-acting and has less tendency to lose its efficacy with continued use than opcon-a.
