Refrigerated till it is opened, After that once opened may be stored in room temperature upto 77 F upto 6 weeks only. This was confirmed by my MD doctor.

Yes, i have a better one the i-drop mirror at the eye drop mirror factory llc. It fits the lanaprost with the basic model px1. It is easy to use and replaces the top on the bottle.

Xalatan (latanoprost) became generic in 2011 when the patent expired. This allowed other pharmaceutical companies to produce and sell generic versions of the medication.
