How does this medication work? What will it do for me?
Spironolactone and hydrochlorothiazide both belong to the family of medications called diuretics (water pills). This combination medication is used to treat edema (fluid retention) that occurs with congestive heart failure and disorders of the kidney and liver. This combination of medications is also used to treat high blood pressure. It works by making the body lose excess water and salt.
One of the diuretics, spironolactone, is called a potassium-sparing diuretic and helps the body to retain potassium. Hydrochlorothiazide, on the other hand, causes potassium to be lost from the system. Potassium supplements are usually not required with this medication as the effects of the two diuretics balance each other out. This medication is normally used once the best strength of each of the ingredients is determined individually.
