What is a common side effect that must be monitored in patients starting new psychotropic medications?

Orthostatic hypotension is a common side effect that requires careful monitoring in patients beginning treatment with new psychotropic medications. This phenomenon occurs when a patient experiences a significant drop in blood pressure upon standing, which can lead to dizziness, lightheadedness, or even fainting. Such reactions are particularly associated with certain classes of psychiatric medications, including antipsychotics and antidepressants.

Monitoring for orthostatic hypotension is vital because it can pose safety risks, particularly in patients who may already be at risk due to other medical conditions or medications. Ensuring that healthcare providers assess blood pressure changes when the patient shifts from a lying or sitting position to standing is important for preventing falls and promoting overall safety in managing psychiatric care.

In contrast to the other options, increased appetite, decreased motivation, and visual disturbances may be relevant side effects as well, but they do not pose the same immediate risk related to patient safety as orthostatic hypotension.
