1. What is Diurex and what is it used for

Diurex belongs to a group of medications known as diuretics. Diuretics increase the need to urinate by reducing the amount of water and salt in the body. Its use helps to decrease and control blood pressure.

Diurex is used to treat high blood pressure (hypertension), as well as to eliminate excessive fluid accumulation in the body due to various causes (edemas).
