Side Effects of Hydralazine

Relaxing the muscles of our body, allowing the blood to move freely in the arteries and veins and also lowering the blood pressure level, are some of the main functions of hydralazine. This drug is a vasodilator which can be used with or without any other kind of medications and it is usually used to treat high blood pressure or hypertension, which (if not treated) can often lead to strokes, various problems related to the kidneys or even heart related problems.
