When diuretics are used

Diuretics are commonly used to treat high blood pressure. Thiazide diuretics usually are one of the first types tried. If diuretics aren't enough to lower your blood pressure, you may receive additional medicine.

Diuretics also are used to prevent, treat or improve symptoms for people who have:

• Heart failure.
• Liver failure.
• Fluid buildup in the body.
• Certain kidney conditions, such as kidney stones.
