Candesartan is used alone or together with other medicines to treat high blood pressure (hypertension) in adults and children 1 to 16 years of age. 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.
Candesartan is an angiotensin II receptor blocker (ARB). It works by blocking the action of a substance in the body that causes the blood vessels to tighten. As a result, candesartan relaxes the blood vessels. This lowers blood pressure and increases the supply of blood and oxygen to the heart.
This medicine is available only with your doctor's prescription.
This medicine comes with a patient information insert. Read the information carefully and make sure you understand it before taking this medicine. Ask your doctor if you have any questions.
In addition to the use of this medicine, treatment for your high blood pressure may include weight control and changes in the types of foods you eat, especially foods high in sodium (salt). Your doctor will tell you which of these are most important for you. You should check with your doctor before changing your diet.
Many patients who have high blood pressure will not notice any signs of the problem. In fact, many may feel normal. It is very important that you take your medicine exactly as directed and that you keep your appointments with your doctor even if you feel well.
Remember that this medicine will not cure your high blood pressure, but it does help control it. You must continue to take it as directed if you expect to lower your blood pressure and keep it down. You may have to take high blood pressure medicine for the rest of your life. If high blood pressure is not treated, it can cause serious problems such as heart failure, blood vessel disease, stroke, or kidney disease.
This medicine also works best when there is a constant amount in the blood. To help keep the amount constant, do not miss any doses. Also, it is best to take the doses at the same time each day.
