How Chlorthalidone Works

Chlorthalidone works by increasing the amount of urine your body makes, which helps to remove excess salt and water.

This action helps to reduce the volume of fluid in the blood vessels, which in turn lowers blood pressure and reduces swelling.

As a thiazide-like diuretic, it primarily acts on the kidneys to promote this effect.
