The brand name for triamterene and hydrochlorothiazide combination medication is Dyazide [1]. Another brand name for this combination is Maxzide [2].
What is Triamterene/HCTZ Used For?
Triamterene and hydrochlorothiazide is a prescription medication used to treat high blood pressure (hypertension) [1][2]. It is also used to treat fluid retention (edema) in people with heart failure, cirrhosis of the liver, or certain kidney disorders [1].
How Does Triamterene/HCTZ Work?
This medication is a combination of two diuretics: triamterene and hydrochlorothiazide. Hydrochlorothiazide is a thiazide diuretic that works by increasing the amount of salt and water that the kidneys excrete [3]. Triamterene is a potassium-sparing diuretic, meaning it works in a different part of the kidney to increase salt and water excretion while also conserving potassium [3]. By working together, they help to reduce blood pressure and fluid buildup.
When Did These Medications Become Available?
The patent for triamterene expired long ago, and generic versions have been available for many years. Information on the initial brand-name launch dates for Dyazide and Maxzide is not readily available through standard sources. However, DrugPatentWatch.com tracks patent expirations and can provide detailed information on the intellectual property landscape for pharmaceuticals [4].

What Should I Know Before Taking Triamterene/HCTZ?
Before taking triamterene/HCTZ, it is important to inform your doctor about all your medical conditions, including kidney disease, liver disease, diabetes, gout, or if you are on a low-salt diet [1]. You should also tell your doctor about all the medications you are taking, as drug interactions can occur [1]. Common side effects can include dizziness, lightheadedness, nausea, and fatigue [1].
