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.
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, 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.
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 (Midamor) or spironolactone (Aldactone).
To make sure triamterene is safe for you, tell your doctor if you have:
diabetes;
heart disease;
kidney disease;
liver disease;
gout; or
a history of kidney stones.
Using triamterene may increase your risk of developing hyperkalemia (high levels of potassium in your blood). You may be more likely to have high potassium if you have kidney disease, diabetes, a severe illness, or if you an older adult.
It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
It is not known whether triamterene passes into breast milk or if it could harm a nursing baby. You should not breast-feed while using this medicine.
Triamterene is not approved for use by anyone younger than 18 years old.
Take triamterene exactly as it was prescribed for you. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Triamterene is usually taken once or twice per day. Follow your doctor's dosing instructions.
Take this medicine after eating a meal.
Taking a diuretic can make you urinate more often, which could disrupt your sleep if this happens at night. If you take triamterene only once per day, take it in the morning to reduce the chance of night-time urination.
While using this medicine, you may need frequent blood tests. Your kidney function may also need to be checked.
Your heart function may need to be checked using an electrocardiogram or ECG (also called an EKG).
This medicine can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using triamterene.
If you need surgery, tell the surgeon ahead of time that you are using triamterene.
Store at room temperature away from moisture, heat, and light. Keep the bottle tightly closed when not in use.
