Why is this medication prescribed?
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.
How should this medicine be used?
Chlorthalidone comes as a tablet to take by mouth. It usually is taken once a day or every other day after a meal, preferably breakfast. It is best to take this medicine in the morning to avoid going to the bathroom during the night.
