Indapamide 2.5 mg: Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions

What Is Indapamide 2.5 mg?

Indapamide 2.5 mg is a prescription medicine used primarily to treat high blood pressure (hypertension) and, in some cases, to help manage fluid retention (oedema) associated with certain medical conditions. It belongs to a class of medicines known as thiazide-like diuretics.

Although indapamide is often referred to as a “water tablet,” it not only helps the body remove excess salt and water but also relaxes blood vessels, making it easier for blood to flow.

By lowering blood pressure, indapamide helps reduce the risk of serious complications such as heart attack, stroke, heart failure, and kidney disease.

• It relaxes and widens blood vessels, reducing resistance to blood flow.

These effects help:

• Lower blood pressure.
• Reduce the workload on the heart.
• Improve blood circulation.
• Decrease fluid build-up in certain conditions.
