When starting antidepressants, antiepileptics, antipsychotics, diuretics, or tramadol in older adults, which precaution is emphasized?

• A. Monitor serum sodium levels closely.
• B. Increase the dose rapidly to achieve quicker effect.
• C. Ignore hyponatremia risk.
• D. Avoid using these medications in older adults.

Answer: (A)

Starting these meds in older adults is especially risky for hyponatramia, a low sodium state that can quietly cause confusion, dizziness, falls, or even seizures. The Beers Criteria highlights this risk because antidepressants, antipsychotics, antiepileptics, tramadol, and diuretics can trigger hyponatremia more readily in the elderly, who often have reduced kidney function and multiple meds. Because hyponatremia can develop subtly and have serious consequences, the recommended precaution is to monitor serum sodium closely after starting or changing these drugs, including checking sodium before starting and again soon after initiation or a dose change, then periodically thereafter. If sodium drops or symptoms emerge, clinicians should reassess the treatment plan. This approach prioritizes safety while allowing necessary therapy rather than avoiding these medications altogether.
