When diuretics are used

Thiazide diuretics are recommended as one of the first medicines to treat high blood pressure.

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 in people who have:

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