I worked in an ophthalmologists office and surgical center for years as an ophthalmic RN and we kept drops, once opened, for 30 days only (which would fall in with the 4weeks that you found documented).

This wasnt because they were no longer potent or that the strength changes-evaporation shouldnt happen that fast if you are only having the cap off long enough to give the drop.

once opened the patency is different because of air mixing in the me where you got the info so I can verify your answer... but since most MD's only know what is in the PDR and I looked in there and it was not mentioned...

The reason we don't use it for more then 3 mos after opening is because of the chance of contamination. only answer was from the UK and it said 4 weeks was patency of multidose containers once opened...

expiration date on the bottle is for the drops in container that is sealed...

I have also been reading to discard for any color change from clear.
