Diuretics are medicines that help reduce the amount of water in the body.
Diuretics are used to treat the build-up of excess fluid in the body that
occurs with some medical conditions such as congestive heart failure , liver
disease, and kidney disease. Some Diuretics are also prescribed to treat
high blood pressure. These drugs act on the kidneys to increase urine
output. This reduces the amount of fluid in the bloodstream, which in turn
lowers blood pressure.
There are several types of Diuretics, also called Water Pills:
- Loop Diuretics, such as Bumetanide (Bumex) and Furosemide (Lasix),
get their name from the loop-shaped part of the kidneys where they have
- Thiazide Diuretics include such commonly used Diuretics as
Hydrochlorothiazide (HydroDIURIL, Esidrix), Chlorothiazide (Diuril), and
- Potassium-sparing Diuretics prevent the loss of Potassium, which is
a problem with other types of Diuretics. Examples of Potassium-sparing
Diuretics are Amiloride (Midamor) and Triamterene (Dyrenium).
In addition, some medicines contain combinations of two Diuretics. The
brands Dyazide and Maxzide, for example, contain the Thiazide Diuretic
Hydrochlorothiazide with the Potassium-sparing Diuretic Triamterene.
Some non-prescription (over-the-counter) medicines contain Diuretics.
However, the medicines described here cannot be bought without a physician's
