What is Dyazide?

Dyazide contains a combination of hydrochlorothiazide and triamterene. 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.

Dyazide is a prescription medicine used to treat fluid retention (edema) and high blood pressure (hypertension).

Dyazide is usually given to people in whom other diuretics have caused hypokalemia (low potassium levels in your blood).

Warnings

You should not use Dyazide if have kidney disease, urination problems, high levels of potassium in your blood, or if you are taking other diuretics similar to triamterene. Do not use potassium supplements, salt substitutes, or low-sodium milk unless your doctor has told you to.

Dyazide can raise your blood potassium to dangerous levels, especially if you have kidney disease, diabetes, severe illness, or if you are an older adult. Call your doctor right away if you have signs of high potassium: nausea, slow or unusual heart rate, numbness, tingling, muscle weakness, or loss of movement in any part of your body.
