Trends in Prescription Medication Usage Among Adults
Prescription medication use has been steadily increasing among adults in the United States and other developed countries. In the U.S., the percentage of adults using at least one prescription drug rose from 1999-2000 through 2007-2008, and this trend has continued in more recent years, with usage patterns influenced by changing health needs, clinical guidelines, and policy changes 2510. For example, from 2015-2018, a significant proportion of U.S. adults reported using prescription pain medications, including both opioids and non-opioid options, with a preference for non-opioid and nonpharmacologic therapies for chronic pain management where appropriate .
In Canada, about 41% of individuals aged 6 to 79 reported taking at least one prescription medication in the past two days, with usage increasing with age and being higher among females and those in poorer health . In Sweden, two out of every three people purchased at least one prescription drug in 2007, and the elderly are particularly likely to use multiple medications, raising concerns about polypharmacy and potential side effects .
Prescription Medication Use in Children and Adolescents
Among children and adolescents in the U.S., prescription medication use is also common, though there has been a slight decrease over time. Between 1999-2002 and 2011-2014, the percentage of children and adolescents using any prescription medication in the past 30 days dropped from 24.6% to 21.9% . However, the use of certain medication classes, such as asthma and ADHD medications, has increased, while antibiotics and antihistamines have seen declines . Concurrent use of multiple medications is notable, with about 7.5% of children and adolescents using two or more prescriptions at once, and a small but significant proportion at risk for major drug-drug interactions, especially among adolescent girls using antidepressants .
In Canada, 23% of children and youth reported using at least one prescription medication in the past month, and 9% used two or more. Usage was higher among those with chronic conditions like asthma, mood disorders, or ADHD. Additionally, 4% of youth aged 14 or older reported misusing prescription medications for non-medicinal purposes . The most common prescriptions for young males were for ADHD, while females more often received medications for depression and hormonal contraception .
Prescription Medication Use Among Older Adults
Older adults are the most frequent users of prescription medications. In the U.S., the use of at least one prescription medication among adults aged 62 to 85 increased from 84.1% in 2005-2006 to 87.7% in 2010-2011. The concurrent use of five or more prescription medications (polypharmacy) also rose, from 30.6% to 35.8% during the same period . This increase in polypharmacy raises the risk of major drug-drug interactions, with about 15% of older adults potentially at risk in 2010-2011, up from 8.4% in 2005-2006 . In Canada, 30% of seniors aged 65 to 79 took at least five prescription medications concurrently . The elderly are particularly vulnerable to the risks of polypharmacy, including side effects and inappropriate drug combinations .
Life Course Patterns and Demographic Differences in Prescription Drug Use
Americans can now expect to spend a significant portion of their lives taking prescription medications—about 47.5 years for women and 36.8 years for men, with the number of years spent taking five or more drugs also increasing substantially . There are notable differences in prescription drug use by race and ethnicity, with non-Hispanic Whites using the most, Hispanics the least, and non-Hispanic Blacks falling in between . In Sweden, disparities in drug use are also seen across gender and social groups, with higher usage among the highly educated and lower usage among people born outside the EU .
Conclusion
Prescription medication use is widespread and increasing across all age groups, with particularly high rates among older adults and those with chronic health conditions. Polypharmacy and the risk of drug-drug interactions are growing concerns, especially for the elderly and for children and adolescents using multiple medications. Patterns of use vary by age, sex, health status, and demographic factors, highlighting the importance of ongoing monitoring and targeted interventions to ensure safe and effective medication use across the population 1234+6 MORE.
