An Overview of Generic Dyazide

Dyazide® (triamterene-HCTZ) is a prescription medication that has been licensed to treat high blood pressure (hypertension) and water retention (edema). It is a combination of two diuretic medications: triamterene and hydrochlorothiazide (HCTZ).
 
Dyazide was first manufactured by GlaxoSmithKline. However, the patent has since expired and generic Dyazide is now available.
