Actually I think what you may be referring to is part of the HIPPA law wherein anything that has your name on it they must return/give to you, with the exception, obviously of the paper prescription you take to them from your Dr. And your # of fills is going to be in the computer system, so it won't go off of the bottle anyway.

Since I always got the same RX's each month, I always had them throw away the information sheets, when HIPPA was enforced they said they had to give them to me now and that I had to be the one to dispose of them since they too had my name and address and Dr.'s name on them, but after a couple of months, I got them to just do the shredding right there at the pharmacy for me.
