Which statement about monitoring for antidepressants is accurate?

• A. They have no significant interactions with other meds.
• B. Hyponatremia is not a concern in older adults.
• C. Sleep disturbances are not monitored.
• D. They commonly cause GI issues, sleep disturbances, sexual dysfunction, weight changes, hyponatremia risk (especially in older adults), and potential increased suicidality in some ages; monitor for serotonin syndrome with polypharmacy.

Answer: (D)

Monitoring antidepressants centers on recognizing a wide range of common side effects and safety risks so you can catch problems early and adjust therapy as needed. Antidepressants frequently cause gastrointestinal upset, sleep disturbances, sexual dysfunction, and changes in weight. Hyponatremia is a particular concern in older adults starting these medications, which can lead to confusion, falls, or seizures if not identified. In younger people, there’s also a risk of increased suicidality, especially when starting treatment or changing doses, so vigilant monitoring in those age groups is essential. When multiple antidepressants or other serotonergic drugs are used together, the risk of serotonin syndrome rises, making it important to monitor for symptoms such as changes in mental status, autonomic instability, and neuromuscular abnormalities.

This option is the best fit because it accurately reflects the range of common adverse effects and safety concerns to watch for, including hyponatremia in older adults and the potential for serotonin syndrome with polypharmacy. The other statements are not accurate: antidepressants do have significant interactions with other medications, hyponatremia can be a real concern in older adults, and sleep disturbances are indeed something clinicians monitor.
