Uses for chlorothiazide

Chlorothiazide is used to treat fluid retention (edema) that is caused by congestive heart failure, severe liver disease (cirrhosis), kidney disease, or from treatment with a steroid or hormone medicine.

Chlorothiazide is a thiazide diuretic. It reduces the amount of water in the body by increasing the flow of urine, which helps reduce fluid retention (edema).

This medicine is available only with your doctor's prescription.

Before using chlorothiazide
