Maxzide treats hypertension (high-blood-pressure)
by flushing water & sodium-salts through the kidneys.
Maxzide combines triamterene (potassium-conserving-diuretic flushes water),
with hydrochlorothiazide (natriuretic flushes sodium-salts).
High-potassium/Hyperkalemia, potential fatal side-effect, needs periodic monitoring.
