What Are Diuretics?

Diureticsare pills that increase urine production.

Theyre also known as water pills, because they help remove water and salt from the body.

Lisinopril-Hydrochlorothiazide Side Effects

Since lisinopril-hydrochlorothiazide combines two medications, you might experience side effects from either drug.

It is not a diuretic and does not have diuretic effects.

However, it is commonly prescribed with a diuretic, sometimes in a combination pill.

While lisinopril itself is not a diuretic, it is often prescribed with one.

ACE inhibitors stop the production of a hormone that causes blood vessels to constrict.

Without that hormone, the vessels relax.

Diuretics work by getting rid of excess water and salt, reducing the volume of the blood.
