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).
chlorothiazide is available only with your doctor's prescription.
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For chlorothiazide, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to chlorothiazide or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of chlorothiazide in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of chlorothiazide in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart problems, which may require an adjustment in the dose for patients receiving chlorothiazide.
