Triamterene

Generic name: Triamterene
Brand names: Dyrenium
Drug class: Potassium-sparing diuretics

Usage of Triamterene

Triamterene is a potassium-sparing diuretic (water pill) that prevents your body from absorbing too much salt and keeps your potassium levels from getting too low.

Triamterene is used to treat fluid retention (edema) in people with congestive heart failure, cirrhosis of the liver, or a kidney condition called nephrotic syndrome.

Triamterene is also used to treat edema caused by using steroid medicine or having too much aldosterone in your body. Aldosterone is a hormone produced by the adrenal glands to help regulate the salt and water balance in your body.

Triamterene side effects

Get emergency medical help if you have signs of an allergic reaction to triamterene: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Stop using this medicine and call your doctor at once if you have:

pale skin, easy bruising or bleeding;

slow, fast, or uneven heartbeat;

jaundice (yellowing of the skin or eyes);

little or no urinating;

signs of a kidney stone - sudden pain in your back or side, vomiting, fever, chills, painful urination, and urine that looks, red, pink, brown, or cloudy; or

high potassium level - nausea, weakness, tingly feeling, chest pain, irregular heartbeats, loss of movement.

Common triamterene side effects include:

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Before taking Triamterene

You should not use triamterene if you are allergic to it, or if you have:

severe kidney disease, or if you are unable to urinate;

severe liver disease;

high potassium levels (hyperkalemia); or

if you take potassium supplements, or another potassium-sparing diuretic such as amiloride, eplerenone, or spironolactone.

To make sure triamterene is safe for you, tell your doctor if you have ever had:

diabetes;

heart disease;

kidney disease;

liver disease;

gout; or

kidney stones.

Using triamterene may increase your risk of developing hyperkalemia (high levels of potassium in your blood). High potassium may be more likely in older adults, or in people with kidney disease, diabetes, or severe illness.

Tell your doctor if you are pregnant or if you become pregnant. Triamterene may harm an unborn baby. However, the benefit of treating edema during pregnancy may outweigh the risk to the baby.

You should not breastfeed while using this medicine.

Triamterene is not approved for use by anyone younger than 18 years old.

You should not use triamterene if you have severe kidney or liver disease, urination problems, or high levels of potassium in your blood. You should not take triamterene if you also take potassium supplements, or other diuretics such as amiloride or spironolactone.

Call your doctor right away if you have signs of hyperkalemia (high potassium), such as nausea, irregular heartbeats, weakness, or loss of movement. High potassium may be more likely in older adults, or in people with kidney disease, diabetes, or severe illness.

You should not take triamterene if you also take potassium supplements, or other diuretics such as amiloride or spironolactone.

Call your doctor right away if you have signs of hyperkalemia (high potassium), such as nausea, slow or unusual heart rate, weakness, or loss of movement. You may be more likely to have high potassium if you have kidney disease, diabetes, a severe illness, or if you an older adult.

Avoid drinking alcohol, which can increase some of the side effects of triamterene.

Avoid a diet high in salt. Too much salt will cause your body to retain water and can make this medication less effective.

Do not use salt substitutes or low-sodium milk products that contain potassium. These products could cause your potassium levels to get too high while you are taking triamterene.

Avoid becoming overheated or dehydrated during exercise and in hot weather. Follow your doctor's instructions about the type and amount of liquids you should drink. In some cases, drinking too much liquid can be as unsafe as not drinking enough.

Triamterene can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.
