Prescription drugs make complex surgery possible, relieve pain
for millions of people, and enable many individuals with chronic medical
conditions to control their symptoms and lead productive lives. Most people who
take prescription medications use them responsibly. However, the non-medical
use of prescription drugs is a serious public health concern. Nonmedical
use of prescription drugs like opioids, central nervous system (CNS)
depressants, and stimulants can lead to abuse and addiction, characterized by
compulsive drug seeking and use.
Addiction rarely occurs among people who use a pain reliever, CNS
depressant, or stimulant as prescribed; however, inappropriate use of
prescription drugs can lead to addiction in some cases. Patients, healthcare
professionals, and pharmacists all have roles in preventing misuse and
addiction. For example, if a doctor prescribes a pain medication, CNS
depressant, or stimulant, the patient should follow the directions for use
carefully, and also learn what effects the drug could have and potential
interactions with other drugs by reading all information provided by the
pharmacist. Physicians and other health care providers should screen for any
type of substance abuse during routine history-taking with questions about what
prescriptions and over-the-counter medicines the patient is taking and
why.
Trends in Prescription Drug Abuse
In
1999, an estimated 4 million people, about 2 percent of the population age 12
and older, were currently (use in past month) using prescription drugs
non-medically. Of these, 2.6 million misused pain relievers, 1.3 million
misused sedatives and tranquilizers, and 0.9 million misused stimulants. While
prescription drug abuse affects many Americans, some trends of particular
concern can be seen among older adults, adolescents, and
women.
The misuse of prescribed medications may be the most common form of
drug abuse among the elderly. Older people are prescribed medications about
three times more frequently than the general population, and have poorer
compliance with directions for use.
The National Household Survey on Drug Abuse1 numbers indicate that
the sharpest increases in new users of prescription drugs for non-medical
purposes occur in 12 to 17 and 18 to 25 year-olds. Among 12 to 14 year-olds,
psychotherapeutics (e.g., pain killers, tranquilizers, sedatives, and
stimulants) were reported to be one of two primary drugs used.
The 1999 Monitoring the Future Survey of 8th, 10th, and 12th graders
nationwide, showed that for barbiturates, tranquilizers, and narcotics other
than heroin, general long-term declines in use in the 1980s leveled-off in the
early 1990s, with modest increases again in the mid-1990s.
Overall, men and women have roughly similar rates of nonmedical use
of prescription drugs, with the exception of 12 to 17 year olds. In this
age group, young women are more likely than young men to use psychotherapeutic
drugs nonmedically. Also, among women and men who use either a sedative,
anti-anxiety drug, or hypnotic, women are almost twice as likely to become
addicted.
The Drug Abuse Warning Network, which collects data on drug-related
hospital emergency room episodes, reported that mentions of hydrocodone as a
cause for visiting an emergency room increased 37 percent among all age groups
from 1997 to 1999. Also, mentions of clonazepam increased 102 percent since
1992.
Commonly Abused Prescription Drugs
While many prescription drugs can be abused or misused, these
three classes are most commonly abused:
- Opioids - often prescribed to treat pain.
- CNS Depressants - used to treat anxiety and sleep
disorders.
- Stimulants - prescribed to treat narcolepsy and attention
deficit/hyperactivity disorder.
