How It Works
Diuretics cause the kidneys to remove water and salt (sodium) from
the body. This reduces the amount of fluid in the body, lowers blood pressure,
and helps the heart beat stronger. Because these medicines increase urination,
diuretics are commonly called "water pills."
Why It Is Used
In children who have
congenital heart defects, diuretics often are given to
treat symptoms of
heart failure. Diuretics allow the heart to function
more efficiently, which helps improve swelling and breathing difficulty.
How Well It Works
Diuretics reduce the amount of extra water in the body, thereby
relieving symptoms such as shortness of breath.
Side Effects
The most common side effects of diuretics include:
- Frequent urination.
- Reduced levels
of chemicals (such as potassium, magnesium, and sodium) in the blood. Low
potassium can lead to irregular heartbeats.
- Weakness.
- Dehydration.
See Drug Reference for a full list of side effects. (Drug Reference
is not available in all systems.)
What To Think About
Some diuretics need to be taken with potassium pills or with a diet
that has enough potassium (found in citrus fruits, bananas, tomatoes, and other
foods).
A person may need regular blood tests while taking diuretics to
monitor the levels of chemicals such as potassium in the blood.
