Chlorthalidone is a medication commonly used to treat high blood pressure and fluid retention. It belongs to a class of drugs known as thiazide diuretics, which help the body eliminate excess salt and water through urine. By reducing blood volume, Chlorthalidone can lower blood pressure, making it easier for the heart to pump blood. In addition to managing hypertension, Chlorthalidone may also be prescribed for conditions like heart failure and certain kidney disorders. Patients taking this medication should be monitored for potential side effects, such as electrolyte imbalances, and should maintain a balanced diet to support their overall health.
