What Is the Impact of Free
Drug Samples on Patients?

W
hat is the impact of free prescription drug samples
upon the US healthcare system? Is this a timely and
important question to ask? According to studies using the US
Medical Expenditure Survey (MEPS), 12% of Americans
have received at least one free sample of a prescription drug.
The value of these drug samples has increased from $4.9
billion in 1996 to $16.4 billion in 2004. During these same
years, spending for prescription drugs has risen 15% and now
accounts for 10% of total healthcare costs.

It is unquestioned
that the gains for the drug companies from this increase in
spending for prescriptions surpass the threefold increase in
the value of free samples.
The drug companies’ motivation for providing these free
samples raises certain questions: are the free samples meant
to create and/or increase the market for these drugs? Are the
providers, when they dispense the samples provided to them,
being used as mini-marketing machines for the drug compa-
nies? Many providers believe that the answer to these ques-
tions is “no.” They see the availability of drug samples as a
way to give free medication to patients with limited incomes.
If the answer to these questions, however, is “yes,” there
should be a measurable impact on the providers’ prescribing
habits and on patients’ drug purchases.
Numerous studies, including the one published in this
edition of the SMJ, show a much more complex interaction
among free samples, providers and patients. This study found
that physicians, if brand name samples were no longer avail-
able, were three times more likely to prescribe generic drugs
for their uninsured patients. With or without the availability
of samples, Medicaid patients would typically be prescribed
generics.

found that a higher percentage of
patients with uninterrupted health insurance received free
samples compared to those who were uninsured for part of
the year. Lurk et al
1
showed that removal of drug samples
served to increase patients’ out-of-pocket drug costs.
These results make it appear that some providers are
using the availability of drug samples to address an array of
patient prescription needs, e.g., free samples can provide drugs
for those patients unable to afford to fill their prescriptions.
The number of such patients, according to a national study by
the Center for Studying Health System Change, equals 14
million American adults. Providers are also not prevented
from giving free samples to patients who have health insur-
ance. According to the same study, these insured patients
could be part of the 15% of those with chronic conditions
who do not fill at least one prescription a month due to cost.

No easy answer exists to the question of whether or not
these are good uses of drug samples. A positive aspect: pro-
viders, as these studies show, are sensitive to their patients’
out-of-pocket drug costs and that these costs affect the utili-
zation of prescribed drug therapies. A negative aspect: the
provider’s behavior is influenced by a free drug sample pro-
vided with the intent to increase drug company profits, i.e.,
drug samples are given for the newest, most profitable drugs,
not necessarily for the ones needed most by the provider’s
uninsured or underinsured patients. Additionally, these free
drug samples might not be the most effective drug therapies
for these patients. The provider is constrained by market
forces in conflict with patient needs.
The free drug sample dilemma is a symptom of the long-
term influence of the pharmaceutical industry on medical
practice and, in turn, on patient care. A pharmaceutical com-
pany wants access to a market for its drugs and the provider’s
office is the gateway to this market. The problem comes
about due to a clash of differing values. Pharmaceutical com-
panies are in the business of making profits; the more copy-
right protected drugs they sell, the more profits increase.
These companies reach out to providers in numerous ways,
including providing free samples, in order to build or expand
the market for those drugs.
Providers are paid for care to their patients, but only for
direct patient care and/or patient services. They are not re-
imbursed for learning about new drugs on the market and on
the ways these drugs could impact their patients. In order to
obtain this information, they rely in part on those pharma-
ceutical representatives whose mission is profit.
Many in healthcare feel the solution is to constrain the
pharmaceutical companies’ influence. A more comprehen-
