ABSTRACT
Self-medication is a common practice in many developing countries. In Vietnam,
self-medication has grown in recent years due to the increasing availability of drug
vendors and pharmacy shops throughout the country. Beside the convenience, time
and cost saving, self-medication is associated with risks such as misdiagnosis, use
of irrational drug dosage that lead to the harmful consequences not only for patient
himself but also for community as a whole. Investigating the determinants of selfmedication practice of individuals facing illness is helpful for the health policy
makers who are interested in improving the appropriate access of self-medication
in public.
This study focuses on examining the impact of educational level on self-medication
practice in Ho Chi Minh city, the national center of educational and health care of

the country. The descriptive statistics and econometric analyzes have been applied
to answer the question whether the adult individuals with a higher education are
more likely to be self-medicated. The thesis has been employed the theory of
consumer choice as the foundation theory, the Andersen's behaviour model, and
two empirical studies to construct a health-seeking model which describes the way
individuals make choices regarding health care utilization to get the highest level
of utility.
The findings based on the survey conducted by the author in Ho Chi Minh city
show that the more educated individual is, the more self-medication he or she has
in treating minor illness.

CHAPTER 1: INTRODUCTION
1.1 PROBLEM STATEMENT
After the economic reforms initiated in 1986 in Vietnam, the role of public
health sector began to deteriorate which accompanied the emergence of
private sector and the expanding of pharmaceutical industry. Between 1986
and 1994 there was a three-fold increase in drug production and a six-fold
increase in per capita drug consumption (Witter, 1996). The rapidly
expanding drug vendors and pharmacy shops throughout the country have
emerged now acting as an important health care provider. Data from
Vietnam Living Standard Survey 1997-1998 (VLSS, 1997-1998) indicates
that the contact rate with the health care system was dominated by the use of
pharmaceuticals. According to the VLSS 2001-2002, self-medication is very
common practice to deal with illness among Vietnamese households - 73
percent of patients reporting use of self-medication to deal with illness and
most people procure medication for self-medication at pharmacists.
The common practice of self-medication has both positive and negative
aspects. In cases of common illness, such as coughs or colds, self-medication
may be rational behaviour in terms of convenient, time saving and cheap if
patients have sufficient knowledge about common non-prescription drugs.
But in cases of more serious disease, requiring the use of antibiotics or
steroids, or in cases of special status such as pregnancy, babies, people with

1


drug allergies, the treatment without consultation of medical professionals
can lead to harmful consequences. In the latter cases, self-medication
accompanied the lack of ability or awareness of the need to read the drug
information lead to a risky of wasting money, status of sickness may be more

serious. The negative sides of self-medication not only affect the individuals
but also the community. The large scale drug resistance in the community of
Vietnam has increased and reached epidemic levels (Sam, 1993). The future
potency of drug for all users is reduced, which has lead to increasing the
amount of treatment failures, and as the result, leading to longer and more
severe illness and demand for more expensive drugs. This result has
increased financial burden on the poor and those without any medical
knave to use up medicine bought follow prescription recommended by doctor.
