Dyazide uses are concerned primarily with the treatment of high blood pressure and fluid retention. The medication works by causing the body to remove more salt and water from the blood, which causes a decrease in blood volume. This, in turn, helps lower blood pressure. There are no universally accepted off-label Dyazide uses at this time, nor is the medication approved for use in children.
An Overview of Dyazide UsesDyazide® (triamterene-HCTZ) is a prescription medication that has been licensed to treat a couple of conditions. These specific Dyazide uses can include:
The medication should be used only in people who develop low potassium levels (hypokalemia) while taking hydrochlorothiazide or in people who cannot risk low potassium levels (due to other medical conditions).
Dyazide Uses for High Blood PressureA blood pressure reading consists of two numbers -- for example: 120/80. The top number is known as the systolic blood pressure, and the bottom number is the diastolic blood pressure. High blood pressure is defined as an average blood pressure higher than 140/90 with multiple blood pressure readings.
In previous clinical studies, Dyazide has been shown to significantly lower both systolic and diastolic blood pressures. By lowering blood pressure, the medication can decrease the risk of developing health problems -- such as a stroke, heart disease, or congestive heart failure --- that often occur with long-term high blood pressure (see Effects of High Blood Pressure). Dyazide is not a cure for high blood pressure, however.
