Uses For valsartan
Valsartan is used alone or together with other medicines 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 reduce the risk of strokes and heart attacks.
Valsartan is also used to treat heart failure and left ventricular failure after a heart attack. Left ventricular failure occurs when the left side of the heart (the main pumping chamber) becomes stiff and enlarged or swollen. This causes pooling of blood in the lungs because the heart is not pumping properly.
Valsartan is an angiotensin II receptor blocker (ARB). It works by blocking a substance in the body that causes blood vessels to tighten. Valsartan relaxes the blood vessels and lowers blood pressure. A lower blood pressure will increase the supply of blood and oxygen to the heart.
valsartan is available only with your doctor's prescription.
Before Using valsartan
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For valsartan, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to valsartan or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
