What Is Chlorthalidone Used For?
Chlorthalidone Uses for Water RetentionOne common cause of water retention is congestive heart failure (CHF). This is a condition in which the heart cannot pump enough blood throughout the body. It does not mean that your heart has stopped or is about to stop working. Rather, it means that your heart is not able to pump blood the way that it should. This can lead to symptoms of CHF that include:
- Shortness of breath
- Swelling of the feet, ankles, or lower legs
- Rapid weight gain (see Symptoms of Congestive Heart Failure).
Other causes of fluid retention can include kidney failure (renal failure), cirrhosis, estrogens, and corticosteroids.
Chlorthalidone can help with water retention by helping the body get rid of the extra fluid. The medication is approved to treat water retention (also known as edema) when used with other medications, including other congestive heart failure medications. However, chlorthalidone does not cure congestive heart failure or other conditions that cause the body to retain fluid.
How Does Chlorthalidone Work?Chlorthalidone is a diuretic. These medicines are commonly referred to as "water pills." Chlorthalidone works by increasing the amount of salt and water the kidneys remove from the blood, which are passed out through the urine. By increasing the amount of water removed from the blood, the medication causes a decrease in blood volume. Because of this effect, chlorthalidone can lower blood pressure and also help with water retention.
