Benzodiazepines in older adults are associated with which risk?

• A. Hypertension
• B. Increased fall risk
• C. Weight gain
• D. Skin rash

Answer: (B)

Older adults are especially sensitive to the sedative and muscle-relaxant effects of benzodiazepines. These drugs can cause dizziness, unsteadiness, and slowed reflexes, which impair balance and coordination. Because aging often brings gait instability, arthritis, and multiple medications, the combined CNS depressant effects and slower drug clearance in older adults increase the likelihood of falls. Falls are a major safety concern in this population, making increased fall risk the most significant adverse outcome associated with benzodiazepine use.

Hypertension, weight gain, and skin rashes are not typical, central risks from benzodiazepines in older adults, whereas falls due to impaired balance and cognition are well-documented and clinically important.
