This medicine contains the active ingredient chlorthalidone which belongs to a group of medicines called diuretics, also known as water tablets. These medicines cause the kidneys to produce more urine, and in that way they free your body from retaining the extra fluid. Chlorthalidone is prescribed for the treatment of edema (water retention caused by heart failure), hypertension (high blood pressure), retention of water caused by liver or kidney disease and diabetes insipidus (frequent urination).
