What is a common side effect of Hydralazine?

Hydralazine is a medication commonly used to treat high blood pressure, and one of its well-known side effects is reflex tachycardia. This phenomenon occurs as the body responds to the sudden drop in blood pressure caused by the vasodilating effect of hydralazine. When blood vessels are dilated, the body detects this decrease in blood pressure and attempts to compensate by increasing the heart rate, leading to reflex tachycardia.

This response is particularly common with medications that have potent vasodilatory effects, such as hydralazine, as the body strives to maintain adequate blood flow and pressure. Understanding this side effect is crucial for managing and anticipating reactions in patients receiving hydralazine, allowing for proper monitoring and potential adjustments in therapy if needed.
