When diuretics are used

Thiazide diuretics are recommended as one of the first drug treatments for high blood pressure.

If diuretics aren't enough to lower your blood pressure, your doctor might add other blood pressure medications to your treatment plan.

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

• Heart failure
• Liver failure
• Tissue swelling (edema)
• Certain kidney disorders, such as kidney stones
