What is a potential effect of polypharmacy in elderly residents?

Polypharmacy, which refers to the use of multiple medications by a patient, particularly in elderly residents, often leads to an increased risk of adverse reactions. As the body ages, metabolic processes can change, affecting how drugs are absorbed, distributed, metabolized, and excreted. This can result in a higher likelihood of drug-drug interactions, where one medication affects the efficacy or side effects of another, exacerbating the potential for adverse reactions.

The complexity of managing multiple medications also can lead to confusion about dosages or timing, which further increases risks. Elderly individuals may have multiple health conditions, requiring them to take several medications simultaneously, making them particularly vulnerable to these adverse effects. Careful management and regular review of medications are essential in this population to minimize potential harms associated with polypharmacy.
