Hydralazine is a common medicine used to control high blood pressure. It works by relaxing blood vessels and helping blood flow more easily.

Effects of Hydralazine on the Body
How Hydralazine Works
Hydralazine is a vasodilator which means it works by relaxing the muscles in your blood vessels, especially smaller arteries. This relaxation causes the blood vessels to widen, allowing blood to flow more easily and reducing the workload on the heart. As a result, blood pressure is lowered, which can help prevent strokes, heart attacks, and other cardiovascular issues.
Common Side Effects
While Hydralazine helps control blood pressure, it can also cause some side effects, including:
- Headache: Often caused by the sudden decrease in blood pressure.
- Dizziness or Lightheadedness: Especially when standing up quickly due to a drop in blood pressure.
- Fast Heartbeat (Tachycardia): The heart might beat faster at first to move blood through the widen blood vessels.
- Nausea and Vomiting: Gastrointestinal discomfort is also a common side effect.
- Fatigue: Lowered blood pressure can sometimes result in a feeling of tiredness.

Nocturnal hypotension, or a significant drop in blood pressure during the night, is another crucial reason to avoid taking Hydralazine after 6 PM. This condition can cause dizziness, lightheadedness, and even fainting upon waking.
Plus, taking Hydralazine earlier in the day can help prevent low blood pressure at night, which can affect sleep and heart health. This way, you’ll have more stable blood pressure, better sleep, and better overall health.
