Hydralazine (By injection)
Treats high blood pressure.
Uses of This Medicine
Hydralazine injection is used to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. Lowering blood pressure can increase the risk of heart attacks and strokes.
Hydralazine works by relaxing the blood vessels and increasing the supply of blood and oxygen to the heart while reducing its workload.
This medicine is to be given only by or under the direct supervision of your doctor.
