Cyclosporine
"Restasis works for my sjogrens dry eye, however, the new multi dose bottle does not last 30 days!  I barely got 20 days out of it.  I called the company and was given a one time new bottle at no charge.  I am trying it again, however, I continually have problems getting a consistent dose from the bottle.  This is a horrible design and needs improvement.  the 1/10 rating is for the design of the multi dose restasis bottle, not the vials or the medication itself."
