Why is this drug prescribed: HydroDIURIL is used in the treatment of high blood pressure and other conditions that require the elimination of excess fluid (water) from the body. These conditions include congestive heart failure, cirrhosis of the liver, corticosteroid and estrogen therapy, and kidney disorders. When used for high blood pressure, HydroDIURIL can be used alone or with other high blood pressure medications. HydroDIURIL contains a form of thiazide, a diuretic that prompts your body to produce and eliminate more urine, which helps lower blood pressure.

Since blood pressure declines gradually, it may be several weeks before you get the full benefit of HydroDIURIL; and you must continue taking it even if you are feeling well. HydroDIURIL does not cure high blood pressure; it merely keeps it under control.
