OTHER NAME(S): Hydralazine Tablet

Uses

Uses

Hydralazine is used with or without other medications to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Hydralazine is called a vasodilator. It works by relaxing blood vessels so blood can flow through the body more easily.

How to use Hydralazine HCL

Take this medication by mouth with or without food, usually 2 to 4 times daily or as directed by your doctor. The dosage is based on your medical condition and response to treatment. Your doctor may start you at a low dose and gradually increase your dose. Follow your doctor's instructions carefully.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. It may take up to several weeks before you get the full benefit of this drug.

Do not stop taking this medication without consulting your doctor. Some conditions may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased.

Tell your doctor if your condition worsens (for example, your routine blood pressure readings increase).

Side Effects

Side Effects

Headache, pounding/fast heartbeat, loss of appetite, nausea, vomiting, diarrhea, or dizziness may occur as your body adjusts to the medication. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

To reduce the risk of dizziness, get up slowly when rising from a sitting or lying position.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

This medication may rarely cause nerve problems. Tell your doctor promptly if you experience numbness or tingling. Your doctor may recommend a vitamin B6 supplement (pyridoxine).
