What is a common side effect of medications in elderly patients?

C. Drowsiness or confusion is a common side effect of medications in elderly patients due to several factors. As people age, their bodies process medications differently; changes in metabolism and organ function can alter how drugs are absorbed, distributed, metabolized, and eliminated. This can lead to increased sensitivity to medications, resulting in side effects like drowsiness and confusion.

Additionally, the elderly often take multiple medications (polypharmacy), which can lead to drug interactions that exacerbate these side effects. It is important for healthcare providers to monitor the elderly closely for these reactions to medications and to adjust dosages or switch medications accordingly to minimize such effects and improve the patient's overall well-being.
