A new study published in the Journal of the American Geriatrics Society reveals a concerning trend among adults aged 65 and older. Researchers found that individuals taking five or more prescription medications face a significantly higher risk of death compared to their peers who manage fewer drugs.
Known as polypharmacy, this practice is common, with over 40% of the study participants falling into this category. The data, collected from thousands of adults over an eight-year period, indicates that each additional prescription adds a 7% increase in mortality risk. Even after researchers adjusted for underlying health conditions, the total number of medications remained the strongest predictor of mortality.
Medical experts point out that the human body processes drugs differently as it ages. Organs like the liver and kidneys become less efficient, which increases the likelihood of adverse drug reactions, side effects, and accidental overdoses. Many participants in the study were also taking combinations of drugs that are known to cause dangerous interactions, or medications considered risky for seniors.
While the findings highlight a clear association, they do not establish direct causation. Doctors and pharmacists recommend that seniors take a proactive role in managing their health. This includes conducting periodic medication reviews to confirm that every prescription remains necessary, effective, and safe for their current health status.
Patients are encouraged to bring their full list of prescriptions, over-the-counter drugs, vitamins, and supplements to their next appointment. Asking for a reassessment of these items can help avoid unnecessary risks and ensure that long-term care plans prioritize patient safety.
