Which side effect is commonly associated with antihypertensive drugs?

Postural hypotension is a well-documented side effect associated with antihypertensive drugs. Antihypertensive medications work to lower blood pressure, and as a result, they can cause a significant drop in blood pressure when a person stands up from a sitting or lying position. This sudden change in blood pressure can lead to dizziness, lightheadedness, or even fainting, particularly if a patient gets up too quickly.

Understanding postural hypotension is critical for patients on antihypertensive medications, as they need to be educated about the potential for this side effect to prevent falls or injuries. In contrast, while irregular heart rhythms can occur with some medications, they are not as commonly associated with all antihypertensive therapies. Similarly, anxiety and nervousness might be more related to other classes of medications, and blood disorders are not typical side effects of antihypertensive medications specifically.
