Which of the following best describes the risk that increases with polypharmacy in older adults?

Taking many medications increases the chance of drug interactions and adverse drug events. In older adults, age-related changes in how the body handles drugs—such as slower liver metabolism and reduced kidney function—combine with multiple prescriptions to raise the likelihood that medicines will affect each other or cause unexpected side effects. These interactions can lead to confusion, dizziness, bleeding, electrolyte problems, or organ harm, and they’re a direct result of polypharmacy. Falls and fractures can happen as a consequence of these adverse effects, but the broader and more fundamental risk from taking many drugs is the increased potential for interactions and medication-related harm. Hypertensive crises or renal failure may occur in specific scenarios, but they don’t capture the general risk as clearly as “drug interactions and adverse drug events.”
