Description and Brand Names
US Brand Name
Chlorthalidone 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. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.
Chlorthalidone is also used to treat fluid retention (edema) that is caused by congestive heart failure, severe liver disease (cirrhosis), kidney disease, or treatment with a hormone or steroid medicine.
Chlorthalidone is a diuretic (water pill). It reduces the amount of water in the body by increasing the flow of urine, which helps to lower blood pressure.
Chlorthalidone is available only with your doctor's prescription.
