Patient Education

Chlorthalidone


Chlorthalidone, a 'water pill,' is used to treat high blood pressure and fluid retention caused by various conditions, including heart disease. It causes the kidneys to get rid of unneeded water and salt from the body into the urine. This medicine is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Triamterene


Triamterene is used alone or with other medications to treat edema (fluid retention; excess fluid held in body tissues) caused by various conditions, including liver and heart disease. Triamterene is in a class of medications called diuretics ('water pills'). It causes the kidneys to eliminate unneeded water and sodium from the body into the urine, but reduces the loss of potassium.

Blood Pressure Medicines


High blood pressure, also called hypertension, usually has no symptoms. But it can cause serious problems such as stroke, heart failure, heart attack and kidney failure. If you cannot control your high blood pressure through lifestyle changes such as losing weight and reducing sodium in your diet, you may need medicines.

Blood pressure medicines work in different ways to lower blood pressure. Some remove extra fluid and salt from the body. Others slow down the heartbeat or relax and widen blood vessels. Often, two or more medicines work better than one.
