What is hydrochlorothiazide and triamterene (Dyazide)?

Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention.

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

The combination of hydrochlorothiazide and triamterene is used to treat fluid retention (edema) and high blood pressure (hypertension).

Hydrochlorothiazide and triamterene may also be used for other purposes not listed in this medication guide.

What is the most important information I should know about hydrochlorothiazide and triamterene (Dyazide)?

Do not use this medication if you have kidney disease, urination problems, or high levels of potassium in your blood. Do not use potassium supplements or other diuretics while you are taking hydrochlorothiazide and triamterene.

Before using this medication, tell your doctor if you have heart or liver disease, diabetes, a breathing disorder, gout, lupus, or a pancreas disorder. Tell your doctor if you use a steroid or another blood pressure medicine.

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

This medication 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.

If you are being treated for high blood pressure, keep using this medication even if you feel fine. High blood pressure often has no symptoms.
