Dyazide Side Effects Center

Medical Editor: John P. Cunha, DO, FACOEP

Dyazide (hydrochlorothiazide and triamterene) is used to treat fluid retention (edema) and high blood pressure (hypertension). It is a combination of hydrochlorothiazide, a thiazide diuretic (water pill), and triamterene, a potassium-sparing diuretic. This medication is available in generic form. Common side effects include dizziness, lightheadedness, headache, or upset stomach as your body adjusts to the medication.

The usual dose of Dyazide is one or two capsules given once daily, with monitoring of serum potassium and of the clinical effect. Dyazide may interact with lithium, amphotericin, methenamine, steroids, blood thinners, insulin or oral diabetes medicine, laxatives, ACE inhibitors, indomethacin or other NSAIDs (non-steroidal anti-inflammatory drugs), or other medicines that make you light-headed (such as cold or allergy medicine, narcotics, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety). Tell your doctor all medications you use. During pregnancy, Dyazide should be used only when prescribed. It is unknown if triamterene passes into breast milk. Hydrochlorothiazide passes into breast milk, but is unlikely to harm a nursing infant. Consult your doctor before breast-feeding.
