Patient medication noncompliance is a major public health problem that
represents a significant cost to our health care system. Health care
professionals-through counseling programs, and the pharmaceutical indu
stry-through various improvements in drug products, have helped to imp
rove medication noncompliance. Yet, additional research needs to be co
nducted on noncompliant behavior and into methods to improve it. All h
ealth care professionals, particularly those involved in selecting and
guiding drug therapy decisions, need to be made aware of the costs to
the health care system that result from noncompliance.
