The percentage of Americans taking five or more prescription drugs increased 70% between 1999 and 2008, according to a new report from the Centers for Disease Control and Prevention. One-half of Americans used at least one prescription drug in 2007-2008, and one in 10 used five or more.
The most common prescriptions were asthma medicines for children, central nervous system stimulants for adolescents, antidepressants for middle-aged adults, and cholesterol and blood pressure drugs for older Americans. Those without health insurance or a regular place for health care were less likely to use prescription medications than their counterparts.
