What is a common side effect of antihypertensive medications that the nurse is teaching the spouse to watch for?

A significant side effect of antihypertensive medications is the potential for falls, primarily due to their influence on blood pressure regulation and the risk of hypotension. Antihypertensives can cause dizziness, lightheadedness, or even fainting, especially when a patient transitions from sitting to standing. This orthostatic hypotension can increase the risk of falls, which is particularly concerning for older adults or those with balance issues.

Monitoring for symptoms like dizziness after standing or changes in balance can help the spouse be vigilant in preventing falls. Educating caregivers and family members about this risk ensures that they can provide support and assistance as needed, particularly in the first few days after starting a new medication or adjusting dosages.
