That is a great idea.  Another thing that I do so that we don’t run low on any of our meds (between my daughter, my husband and myself we have quite a few!) is when we get a new/refill prescription, I immediately mark on the calendar the day it will be available for refill at the local pharmacy or day to send/call in for the refill from mail order and highlight it.  If it is the last refill, I make sure I call the dr that very day to request a new prescription.  I have learned not to leave it to memory or to rely on my husband or daughter to tell me before they run out :-)
